The Problem with Electric Vehicles

- switching all cars to electrical would increase the total electricity consumption by 20%, while currently we export about 10% of our production. All the changes are going to happen over a timeframe of more than 20 years, because that is how long it takes to replace the cars at minimum, a long time to make any necessary adjustments to the grid.
- in general, electrical cars should be rather beneficial to the grid. There is no reason to charge them at dinner time. Electrical cars have timers and current control, it is very easy to have them charge at times where the grid is underloaded. Many power companies have rebates at night anyway to get rid of excess electricity. (Assuming a car with a reasonably sized battery, like the Model 3)
- long term, the speed of charging could be controlled remotely by the power company (for a rebate) so they could use this further to stabilize the grid.
- The Model X is available with a tow hitch, and it seems that the Model 3 might have one too (Elon tweeted something to that extend)
- Most Tesla owners seem to be happy with the combination of range and the Supercharger network, and the range is going to improve by about 5% per year.

For areas without the rebates in place they can track the carbon content of your local grid and charge only when wind turbines are producing strongly.
My main issue is with your notion that the cars should, somehow, be limited to only charging at certain times. The issue becomes, "OMG I CUT OFF MY FINGER". "Oh, sorry, cars not charged yet." "Oh, I want to go to Walmart and grab some chips." "Sorry, cars not charged yet." "Oh man! I forgot about a meeting I had with my realtor!" "Sorry, cars not charged yet"
> "There's no reason to recharge them at dinner time."
The issue is that this could be a problem now. Instead of me just being able to put fuel in my car whenever, now I have to be like "Oh yeah, it's dinner time and I'm home. Can't recharge my car yet!"
AND, when everyone has an electric car, it will very quickly become like a busy cable network in your neighborhood. "Well, it's estimating 18 days until the ~download~ charge is done."
Refueling with an ICE takes no time at all and can be done anywhere. Even if the car is out of gas in my driveway, I have a chance to walk and get a can of fuel and put fuel in my car (in probably less time than it would take to recharge it).
I would bet that the "power company's night time rebates" would go away really fast when they were struggling to meet the sudden demand of charging everyone's cars.
> Most Tesla owners are happy with their range and it will improve by 5%/year.
Even if their current range is 300 miles, that's 15 miles the first year. That's not really significant.
Lastly, your disagreements all seem to be either flawed or they seem to be with the less important issues (tow hitch, range) and ignore the more important (charge time, accessibility, cost, cost of infrastructure, etc).
Very few people will use the entirety of 200+ miles every day, and as such, their car will not be empty. It will then simply recharge every night. Also, nobody is saying you can't recharge when you want. It's just that 95% of people won't care when exactly in the day their car recharges the 50 odd miles they drove, and so that will then happen at a useful (for the grid) time.
So right.
It is truly amazing that more people don't realize the disconnect here between current motor fuels and electricity. The average gallon of gasoline contains 33 kWh of energy. You can pump about 15-20 gallons in 5 minutes or so. That's equivalent to around 6 MWh or 21,000 MJ of energy, every hour. Less if you allow for the time between cars. The average household electrical supply in the US is 200A at 240V which can supply a paltry 48 kWh or 172 MJ each hour. And that's if one were able to use the supply at full capacity.
Electric cars require 1/4 to 1/3 of the energy as typical ICE counterparts, but the fuel delivery systems are separated by factor of over 100. We're still well over an order of magnitude apart on the fueling convenience factor. Installing three phase 480V 400A (1.2 MJ per hour) service to homes would help solve this, but would be much more dangerous to work with - even if the charging systems on the EVs could use it.
The comparison about the energy transfer speed between gasoline and electricity is misleading. First of all, an electric vehicle is about 3x as effective, so you would need only a third of the energy transfer speed.
Then, with a gasoline vehicle, you have always to drive to a fuel station and wait for it to be filled up - there speed matters. With an electric vehicle, the common case should be overnight recharge, so charge speed does not matter much there. This also means, that you are likely to start with a completely filled battery every morning. So unless you are doing long distance travel, you never have to recharge except over night (or, if your work parking facilities offer electrical outlets, during work time). And for long distance travel, there are Superchargers. Yes, those do take longer than refueling gasoline, but unless you travel long distance every day, this might be a good tradeoff.
I stated that in my original reply.
> With an electric vehicle, the common case should be overnight recharge, so charge speed does not matter much there.
I know here in the DC metro people have 100 mile per day commutes - and more. That is 1/3 to 1/2 (all in some cases) of the battery capacity of most EVs. A regular 20A wall charger has no chance of replenishing that overnight, and at 85% charging efficiency, a level 2 charger or whatever would struggle to supply 40+ kWh over night as well.
Slow charging EVs may work for some, maybe even most - but definitely not everyone. Especially in the rural United States.
In Europe you're unlikely to be travelling vast distances on a regular basis, whereas it's much more common in the US, so the range problems become much more important in the US than they are in Europe.
In Germany they have 3-phase wiring right into homes, so even faster home charging is possible there.
(The CCS plug standard has been future-proofed to support these kinds of speeds)
All of this is only a concern, of course, for long-distance road trips. Which for most drivers are relatively rare events.
I find Jacques' concerns to be well thought out, showing that he has actually dug into the numbers. However, I'm interested to know what you see are even more significant problems.
Oddly enough for HN, its a scalability problem (LOL). If you turned the entire known planetary stock of economically useful lithium ore into present gen batteries with 100% efficiency (LOL) and eliminated all competing uses (LOL), depending who's goofy numbers you use, you could give every human on the planet roughly one electric car. Once. There on its relying on recycling, or the market absorbing dramatically more expensive sources of lithium, or income inequality making a car lifestyle unavailable to most people, etc.
Its a kin to the argument of take the amount of copper in the infrastructure of the USA and divide it by the number of people in the USA and multiply that by the population of the undeveloped world, and you end up with more than the worlds known copper reserves. Africa, for example, will never be electrified at least as we in the west understand electrification. Perhaps new technologies or new ways of looking at things... but just picking up the plans for the TVA and dropping them in the 3rd world is literally not physically possible with existing known metal reserves.
Universal EVs are no problem for every status signalling coastal yuppie, theres just not that many of them. If the developed world retains hegemony we MIGHT be able to switch as a culture completely to EVs. But "the world" is not switching to EVs unless the global population shrinks to fit the global resource limits or ... ?
Note that my numbers assume 100% of the world supply is mined AND 100% efficiency (LOL) and there are no limits. I'm not claiming that 1% of that is realistic, but I am claiming its the very hard upper bound is too low even in some kind of star trek post singularity magical handwave world. Maybe you could fuse hydrogen atoms into lithium in a fusion reactor for a hundred years to make the worlds most expensive battery...
I'm not even sure we can pull it off with low range lead acid batteries in low range cars. When discussing infrastructure type stuff, there are only so many pounds of "stuff" currently economically available given current refining technology per human being. There IS enough iron to give us all cars (maybe not crude oil, but at least iron won't be the limiting factor) but there is literally not enough economically lithium recoverable on this planet, at the current technology level.
Also, 1 car per person is probably more than is necessary.
How much is "economically useful or available" lithium is interesting as what makes sense to access now with current technologies changes as demand increases. More expensive techniques get pioneered and then the access cost drops for the technique as it gets optimized - much like the recent fracking boom.
Right now there is very little demand for lithium compared to the economically recoverable reserves. But the way mineral discovery works, as demand increases more money and effort is invested in finding new resources. There is absolutely no danger that ever-expanding lithium reserves will ever be exhausted by any reasonable vehicle production numbers. It's not even a given that per-pound prices would have to increase, as shown by the success of enhanced oil recovery having a break-even in the $30/bbl range now.
Lithium is also just about the least expensive part of battery production. The cost of lithium in the market could increase by an order of magnitude and only affect battery cost by perhaps 10-20%.
It's not reasonable to project 1 vehicle per person globally for many reasons. Economics, geography, the built infrastructure, and demographics affect vehicle ownership. The techno-society changes such a massive increase in vehicles would bring are enormous and unlikely to evolve soon. Transport paradigms that work in one area, say the US, aren't likely to work in all others. Using US vehicle numbers as a world-wide projection just isn't reasonable.
A more reasonable thought exercise would be to replace all the vehicles in existence with electrics. At about 1 billion vehicles on the road today, there's plenty of lithium to do so, even at current known reserves.
Every EV that replaces a regularly driven ICE vehicle is a net win on its own (less pollution in cities, less energy use, works well with renewables etc.) The more the better.
EVs have lots of benefits for developing nations too, EV scooters and electric bikes seem to be big business in certain areas.
It's not exactly as if I started looking at EVs only recently, I've spent quite a bit of time on keeping up with industry publications, owned one of the first hybrids when they first rolled off the line and try very hard not to spout nonsense. Tech curves definitely will play an important role in mitigating these issues but are in and of themselves probably not enough to allow for a complete electrification of our transport needs.
> the true problems are going to be far different.
Such as?
Maybe more interesting angles could have been supplying the gigantic increase in demand for metals required to produce EV batteries, or the regulatory/industrial battle the EV industry faces with the traditional auto and oil industries (notably the Koch brothers).
We are all interested in how technology will change our lives and solve problems but many folks aren't willing to consider that actually solving some problems requires living in a way which is intrinsically different. It might very well be possible that "tech curves" will eventually solve the problem of transitioning everyone now driving gasoline cars to electric but that is perhaps a localized optimization.
Maybe to _REALLY_ solve the problem requires us to re-consider the way we're living. Is it really sane to live 20-50 miles away from where one works and drive a car in bumper-to-bumper traffic as a daily commute? Sure, if the cars were electric, a larger fraction of the energy wasted doing this would be "renewable" or at least "greener" but what about the wasted time, erosion of well-being, and the continued waste of space. Yes, even electric cars need highways, parking lots, and cities which force themselves to be car-scaled rather than human-scaled. How much would we really solve by the transition to electric cars?
These are not considerations which are easy to talk about, but they're the "true problems" which are being swept under the rug by techno-optimists.
Certainly lifestyle transitions will require decades, after all, it took decades to cities to become car-centric. But can happen even within a generation. Many millennials eschew car ownership and are moving back to cities, whereas for baby boomers the car was a rite of passage as well as its concomitant house in the 'burbs.
Transitioning entirely to electric vehicles will also take decades (admittedly it would be less time because car-years are much quicker than people-years).
What will happen is some mixture of both of these along with random jags of reactionary fascination with the happy-motoring era and who knows what else.
Ultimately, we only have a finite quantity of fossil fuels and there is no "free-refill" for the planet. At some point, lifestyles will have to change drastically to accommodate this limitation as population continues to grow.
Even though my commute is quite pleasant: a 20-minute drive on quiet country roads then a 30-minute bus trip followed by a 10-minute walk to the office, I think about this quite a lot. Especially during the "drive on country roads" bit.
I live in a rural area and I really like it where I live, for any number of reasons. I have absolutely no desire to move back to the city that I work in, even though when I was living there I had a lot of fun.
Life is better when it's simpler and one way I can make it simpler is by either working remotely (not a possibility with my current employer), or becoming self-employed. Wasting time commuting, no matter how enjoyable the commute, is still wasting time.
Are EVs the endgame? I suspect not. Apart from anything else I think it's going to prove far, far harder to replace trucks than buses and cars with EVs.
Would we be better investing in public transport that's convenient and reliable enough people want to use? Certainly. But we like personal vehicles. They're not going to go away easily.
In fact just like horses and steam trains became a leisure pursuit, I suspect ICEs will also become something for play. The old v8 classic, the motorbike, the quad. You might have increasing difficulty getting fuel, so start lugging 5g jerry cans around in your EV to fuel the Mustang weekend toy. EVs can't beat the soul and sound of a v8 or Triumph triple.
As you said, I doubt ICE cars will go away completely. There's too much hobby/enthusiasm behind them for that to happen.
Trucks, buses, and planes will take much, much longer to phase out because of their extreme needs; e.g. light, compact power with a huge range.
Any other problems outside the vehicles themselves will be solved very quickly as they gain more market share.
If you need something to haul a big caravan for holiday, or trailer for a move. Just rent - the rental shops will expand to fit nicely. Probably a nice big diesel.
The v8 offroader that actually works offroad, the truck, and shipping are on diesel for the forseeable.
I don't even see the space requirements to cater for EVs charging needs as much of an issue. We already have service areas on motorways in Europe. Huge spaces with a petrol station in the far corner. We'll have to adjust to 500 mile journeys including a couple of rest/coffee breaks. If you have young kids they already do. Only difference is plug the car in before going inside.
We might have to resurrect a few diners (with charging) along the way on rural or non motorway roads. I think I like that.
Unfortunately, my commute is a bit further (almost 50 miles), which left almost nothing in the slightly aged battery, and caused a "non linear" increase in charge time (without getting a 220 V upgrade charger)
The car (Leaf) was plenty peppy, but the range dropped considerably when going 65 to 70 MPH on the freeway, vs 30 to 50 MPH through town. The maintenance schedule was something like "check the break system every 6 months; get new tires every 3 years; replace the battery every 8 years" (or something along that line).
Still, if you have a short commute, or, as a "mom-mobile", getting a used EV is a no brainer (especially if you have cheap electricity like under Sac's SMUD utility). Just rent the vacation car twice a year. When we fly, that's what we do, anyway.
If you had a 220 at your destination then its a no brainer. My parents and in laws are 47 and 42 miles apart respectively. I installed 220v outlets so I can bring my charger with me.
There's an interesting synergy with other technologies. For example, its pretty trivial to prove you'd have to cover the surface of the earth with a ridiculous number of sunflowers to grow enough oil to power the world with biodiesel using existing vehicles.
However, if 99.9% of car miles driven were solar electric, if not more, then its quite realistic to power every rental truck in the world off biodiesel.
My lifetime driving so far is around 200K miles, and I've driven the home depot truck, enterprise rent a car, and u-haul trucks a total of perhaps 200 miles, so a thousandth of miles driven being biodiesel powered doesn't sound terribly unrealistic on average.
The economics don't stack up today for long-distance EV trucking, but it's quite possible that they will in a decade or so, with ongoing incremental improvements in battery costs and energy density.
The limitations now are cost and infrastructure, not technology. If we imagine, say, an HGV with a 500kWh battery pack then it should be able to haul a typical load for hundreds of miles between charges. Fast chargers can be installed at existing truck stops.
HGV drivers in Europe are legally required to take rest periods every 4.5 hours (and can drive for a maximum of 9 hours per day), so stopping for charging on a similar schedule would not have much impact on existing work practices.
350kWh packs are already being used today for double-decker busses in London, which can run all day without recharging. So 500kWh (or more?) packs in HGVs are not unrealistic.
The only exceptional case I can think of is extreme long-haul trucking in remote, off-grid locations (think Australian Outback, or Ice Road Truckers). Those may be the last hold-outs for fossil fuelled vehicles.
An EV light truck is perfect for the final delivery to home or shop, and doubly so in congested inner cities with pollution charges, like London.
I could be wrong, but I thought the London Routemasters were hybrids?
HGV delivery might evolve to a combination of more rail, longhaul diesel HGVs and EV light trucks, or even full EV HGVs where the range is lower. Like making several supermarket drops in a city. Whatever way you look at it, we're already making excellent, and suprisingly quick, progress.
http://www.independent.co.uk/life-style/gadgets-and-tech/wor...
We already see a few EV delivery vans around (Nissan have one based on the Leaf technology). They need to get a bit bigger and have longer range before they'll start replacing all the diesel vans, but we are indeed making progress.
There's various problems with using intermodal rail for things like supermarket deliveries, though, at least in the UK. It's not really compatible with the just-in-time model that supermarkets and other retailers operate, where the supermarket places an order every day based on their real-time sales data which is fulfilled overnight from their large regional distribution centres.
Consider a shift from truckloads of goods to intermodal container loads: you'd be going truck-rail-truck, with all the inefficiencies of transferring between modes. You'd need intermodal freight depots on the outskirts of cities, shunting yards, etc which just don't exist any more. You wouldn't actually be cutting down on city traffic, since the same number of local trips would need to be made anyway.
And the distances involved from distribution centre to supermarket are usually relatively short, so there just isn't a huge fuel saving to be made in using rail.
I would not be surprised to see something on a small scale for u-haul type rental where a rental trailer would come with a small gas generator and a SAE J1772 charger connector on a cord giving you infinite moderate speed range, or at least infinite until 100 miles after you run out of gas. Possibly people would rent those trailers to travel long distances even if they have nothing to actually carry, just to get infinite range. For most of the population, traveling very long distances is very unusual.
Renting trailers is a COTS business model, ditto renting generators, and even the business model of renting medium size building contractor generators mounted on a trailer. Other than adding a weather proof fairing, a larger gas tank, and a COTS plug in EV charger, there's nothing obscure about this fairly obvious future business model.
You might need a software update for the car, so the car understands its safe to drive away with the charger cord still attached.
Let's take a more realistic scenario: That tomorrow all of the existing two car households have one electric car.
> 1. Your average town does not have the power infrastructure to deal with an extra draw of a whole bunch of commuters arriving home roughly around the same time (say, between 5:30 and 7 pm) and all of them plugging their cars in to recharge.
This has easy solutions, e.g. you tell the charging station what time you need the battery charged by and in 95% of cases it ends up doing the charging from 10PM to 6AM, which makes the power grid very happy.
> Rapid charging is actually not so rapid, highway re-charging stations will have to be much larger than current gas stations
But you will also need fewer of them because you can't currently buy gas at home but you can charge your car there. So you're really only talking about the gas stations on major highways, i.e. truck stops, which are already quite large because it's typical for people to stop and eat there already.
And in the one out of two cars scenario, for long trips you could take the gasoline powered car.
> Every highway would be more or less automatically accompanied by a bunch of power infrastructure
Most of the existing high voltage power infrastructure already follows the highways because both go to population centers and are installed in places which are cheap and efficient to claim with eminent domain.
And needing to build infrastructure is only a problem if we build electric cars faster than we can build power infrastructure, which we probably won't.
> Re-charging will not work nearly as well when vehicle utilization goes up due to sharing
Which is only a problem for the subset of vehicles used for sharing and there is no reason they can't be hybrids instead of pure electric.
Alternatively the people who purchase cars for this purpose could use cars with swappable batteries and leave one charging while the other is on the road and then swap them as needed.
> If a substantial chunk of our energy consumption due to transportation needs is going to shift from being directly petroleum based to being mostly based on the timely delivery of electrons in vast quantities and to a very large number of locations then we will have to invest massively in both generating capacity and grid capacity.
That isn't necessarily true. If most electric vehicles are charged at night then they'll be using the idle capacity of the existing grid rather than requiring new capacity to be built.
Of course some new capacity may be necessary, but that doesn't seem like any kind of insurmountable problem. We already know how to do that.
> Range
This is a problem exactly where it's a problem. Future electric cars may or may not solve it, but in the meantime you know what kind of driving you do. If you take long trips for business, buy a hybrid. If you have a two car household, buy one electric car and one hybrid and take the hybrid on long trips. There is no law that says 100% of cars have to be electric; they can work where they work.
> Trailers
Range when towing a trailer is generally not that important because even if a lot of people do it periodically, they don't do it very often. And this is again solved by having a family buy one EV and one hybrid and using the hybrid for what the EV is bad at.
> Service
This is clearly a problem exclusive to early adopters. If electric cars were half of all cars it wouldn't exist.
> Tax Breaks
I'm not sure how this one is even supposed to be a problem. All else equal, tax credits increase tax rates because the money has to come from somewhere. If everybody buys an EV then everybody gets the credit and the government raises the tax rate so that everybody ends up paying what they would have without it. If half of everybody buys an EV then the government raises the tax rate half that much and there is a significant tax advantage if you buy an EV, which was the whole idea. The credit can never bankrupt the government because the government also sets the base rate.
I live in sunny MA, where in the winter we average 15kWh generated to the summer we average 50kWh. My commute is 60 miles per day which is around 6-8kW depending in traffic and weather.
Also, my local power is a mixture of nuclear and wind.
So. Can we please stop rolling coal burning power plants into the electric car equation as if it is universally applicable.
The car was affordable: $12k second hand. The solar was $0 down and half the national grid per kW. My commute is at the edge of viable for a first gen electric car (really looking forward to the 200mile range of 2nd gen).
I do the vast majority of my charging is at home. My only issue is that the current system (sic) takes DC power converts to to AC only rectify it back to DC in the car. There is still a need for charging stations, but for rare 100 mile journeys. Drive 80 miles charge for 20 minutes, drive 80 miles. 2nd gen it's 160 miles, charge for 40 minutes. We have family in Western MA, which is 150 miles away. With a 200 mile range we'd do it in a single charge and recharge at their house. The use of a charging station is really rare, not part of the routine of ownership, like it is with ICE.
We don't have the infrastructure? We don't need the infrastructure. You can run an electric car almost entirely from energy reclaimed from the environment around your house. It will even store it for you in those handy, replaceable lion batteries it has, solving some of renewable energies gnarlier problems.
Whilst I understand that electric cars don't work well for people who travel more than 100 miles without a 20 minute break, that number is about to shift to 200miles... and that is virtually nobody. The infrastructure problems are solved by local generation (either municipal renewables or home solar). The recharging problem, even at 100mile range isn't a problem, you just charge it at the end of your journey.
It really doesn't take that long to charge the car after the commute. In winter, chances are that it's from municipal power, summer it's probably from my solar. Either way I'm offsetting my car use with clean, local power.
I think the country/world can accommodate BOTH types of car, ICE and EV. And "none" is also a good choice, in some areas.
It could be done, with right incentives.
I live in a "green" (LEED certified at some level) high-end apartment complex built in 2014 just south of downtown Denver, CO. There are zero electric car charging stations in the gated, enclosed garage. If my apartment complex didn't have the foresight to build at least a few charging stations I can't imagine the hope of retrofitting on some 10, 20, or 30 year old building. Nevermind the vast number of apartment complexes that simply don't have the garage space.
Whilst you may get electricity from renewable sources, and that is good for you, when you look at the country as a whole, renewable sources make up a small percentage of the total electricity produced.
The electric cars problems are mostly magnified by American urbanites. Boston is no exception. It might help if zip cars were predominantly EV, although my urbite friends have mostly replaced Zip with Uber
Why? As the grand-parent post mentioned, it's definitely not applicable everywhere, and transportation is the sector where we are the most closely tied to petroleum as an energy source.
Just decoupling that, even if there aren't any gains for the environment in gas-powered regions, is a win in my book. Once we're decoupled, we can start looking at these problematic power plants, and replacing them with greener alternatives.
Also, in regions like Canada, we're all mostly hydro-powered anyway, so the gain would be immediate. Even then, a gas power plant would probably pollute way less than the equivalent fleet of cars, due to the fact that we're always running our engines cold in the winter, which pollutes a lot more than an engine running at the proper temperature.
Unfortunately most of US citizens power comes from non-renewable energy sources. So, I think rolling power plants into the electric car equation is more applicable than not.
"In 2015, renewable energy sources accounted for about 10% of total U.S. energy consumption and about 13% of electricity generation" [0]
But, in my opinion, the best thing to do is to move to a big city and use the trains, or campaign for a good train system in your city, which obviously can't work for everyone.
In case anyone's interested, here's a fairly good and simple explanation of the 3-clutch system which allows the petrol motor to provide some power to the wheels when in the correct scenario: http://www.youtube.com/watch?v=80E1fOp95rA
Emphasis my own.
Using a gas engine just to generate electricity, and then running that through some conversions and battery storage before using it to run drive motors just isn't as efficient as using the ICE to drive the wheels directly. Or maybe GM does a crappy job of it, but the fuel economy figures speak for themselves.
There's graphs of average driving distance, the idea would be to get 90+% of those miles (daily commutes etc.) done with grid-supplied electricity, and the gas engine to be a once in a while thing (assuming you even need one, it is after all an optional extra that you need to pay for on the i3).
At that point you can start to save on the engine expenses too (I think the i3 one is repurposed from a motorbike?)
Yes, but a parallel hybrid powertrain like Toyota's shouldn't be any worse here. The Prius also has a plug-in version which can run on battery alone for a certain distance, and it only spins up the engine when needed for more power or because the battery is too low. Of course, the Prius doesn't have the Volt's all-electric range, but it also has a much smaller battery (and lower price).
— available end-to-end (no waiting for the train and changing lines) — allowing for some privacy (in a car, I am always in good company; not so much in trains) — protect from the elements (riding a bike uphill in cold rain is less than pleasant)
Trains, buses and bicycles are quite inferior options in this regard. Only Uber provides a tolerable alternative (but owning a car is still way cheaper).
But generally speaking, I agree. To convince the average person of a public transit/driverless/generic-alternative-to-driving, privacy and end-to-end-ey-ness is probably important.
"A Texas Utility Offers a Nighttime Special: Free Electricity"
"The women are just three of the thousands of TXU Energy customers who are at the vanguard of a bold attempt by the utility to change how people consume energy. TXU’s free overnight plan, which is coupled with slightly higher daytime rates, is one of dozens that have been offered by more than 50 retail electricity companies in Texas over the last three years with a simple goal: for customers to turn down the dials when wholesale prices are highest and turn them back up when prices are lowest.
It is possible because Texas has more wind power than any other state, accounting for roughly 10 percent of the state’s generation. Alone among the 48 contiguous states, Texas runs its own electricity grid that barely connects to the rest of the country, so the abundance of nightly wind power generated here must be consumed here."
I guess that doesn't compare favorably to $600 (~200*$3) per year for fuel, but it isn't real far out either.
http://www.macrotrends.net/1369/crude-oil-price-history-char...
How do I collect?
There's an implicit requirement for a useful prediction of the price in the GP comment.
But yes who knows...coming regulations may change that number significantly.
www.breitbart.com/big-government/2016/01/12/crude-oil-price-still-crashing-toward-25-breakeven/
I would certainly factor the different cost structures in if I was doing the calculation for real (gas could be $4 in a couple years, who knows).
I still think the bigger bottleneck will be the installation of chargers, though, even though it shouldn't be because they aren't that expensive. But Tesla is just one small car maker installing its own, and the other manufacturers don't seem all that interested in building them for the same reason they've been rather slow in pushing EVs on the market, too. I think governments should have a bigger role in building EV infrastructure.
Consider that wind and solar installations are accelerating (and that wind is so cheap in parts of Texas, its free at night!) and I can assure you, there is no electrical grid burden.

"The UK Department of Transport and teh Royal Academy of Engineering (2010) have both estimated that if the UK switched to battery electric vehicles, electricity demand (kWh) would rise about 16%. The US Electric Power Research Institute modeled 60% of US vehicle use being electric and found a 9% increase in electricity demand. As can be seen from the graphs above, this need not increase the system's peak capacity if most charging is off-peak, thereby greatly increasing the proportion of total generating capacity supplied by base-load plant – see below. A study conducted by the Pacific Northwest National Laboratory for the US Department of Energy in 2006 found that the idle off-peak grid capacity in the USA would be sufficient to power 84% of all vehicles in the USA if they all were immediately replaced with electric vehicles. Areva has calculated that if 10% of cars in France were electric it would increase base-load demand by more than 6000 MWe ("four EPRs", or 10% of nuclear capacity). In the above diagrams, assuming significant move to electric cars mostly charged off-peak, the base-load demand is increased by about 35%."
I won't use the word 'extraordinary', but that's at least a strong claim, so needs strong evidence to back it. Why wouldn't 77% of vehicles mean 77% of the load?
Cars that are 5 years old can have anywhere from 20K to 300K km on them. It all depends on the usage.
Lots of good data here:
http://www.solarjourneyusa.com/EVdistanceAnalysis7.php
People using their cars for 50K to 70K km per year are not exceptional (professional use), private individuals using their cars for < 5K km per year are not exceptional either.
Recharging a drained car battery would use as much power as running a large AC unit for 15 hours, but if the car has driven only a small distance it will use much less power. It all depends on the distance the car needs to drive (logically...).
Deep eye roll at stuff like this.
I hope the author realizes that at some point there wasn't a network of gas stations across the country, there wasn't much of an electrical grid, or a highway system for that matter.
Some of the solutions to these potential challenges are related to public investment, many can be solved by private investment and there is a profit opportunity, thus solutions will come. Better solutions in my mind.
Here's the most missed point I see in all this infrastructure discussion. The most costly piece to next-generation recharge infrastructure already exists, and it is the natural gas "grid". It's massive and empowers much cleaner (than coal) local electricity generation. Today you can buy a small plot of land alongside the highway, pour a concrete pad, install a natural gas generator, purchase gas at bulk rates, and charge EV's for $$$. Even the smallest towns in America have NG lines running near or through them. The highest cost I've seen to have a bulk gas line brought on to a business' property was in the low tens of thousands. You can spreadsheet this, there's profit in this model and it requires NO improvements to the electrical grid and suffers practically no energy loss.
Most of what the author sees as problems others will see as investment opportunities and solve. In fact I think I'm going to go take a look at the map of supercharging stations right now...
Not much of an argument. The ICE won out over electric drivetrains for the express reason that liquid fuels are far easier to provide logistics for than batteries. Most electric car makers stopped production at some point in the 1910s. It's not that electric vehicles were never tried out. They were. Gasoline was just a way better fit.
Right now and for the foreseeable future, EVs are a promising alternative to regular cars, but if everyone hops on board, the logistics will murder us.
EVs won't work until they're actually better than ICEs in every way. Not just some of the ways, all of them. Because only that will make the economics of replacing our entire gasoline-based infrastructure work.
I'm guessing you haven't spent much time behind the wheel of a Tesla. You're making a sweeping and unsupported assertion there.
Was.
See: my argument re: small scale localized electricity production for EV charging thanks to our glorious NG infrastructure.
It was purely logistics, not that energy density of early batteries was logarithmically worse than hydrocarbons?
So EVs at 30% are about 2X as efficient as ICE.
It is inevitable that Tesla (or someone else) will implement Grid-tied battery backup as a standard option on these vehicles.
When that happens -- the Grid gets "free" multi-GWh battery-based load shedding.
Why is this not considered an inevitability? Am I missing something obvious here?
This is also when industrial consumption/ac use peaks, so why would you over produce and feed a battery rather than run a plant/keep places cool...
edit: I do not mean, Purist in any disparaging way, the actual cost of roads (and their maintenance) is enormous. Please read Purist as one who sees the Core or Central problem.
Maybe. It depends on exactly where. He cites simultaneous draw from many commuters at once. If the utilities incentivized slower charging overnight through pricing (which is something that they already do for power intensive industries) then this would be greatly ameliorated. Also, in many places, as noted by the op, people will start charging after getting home from work. If charging is delayed by just 3 hours, they will merely be using capacity that already exists for running air conditioners.
Problem 2: Rapid charging is actually not so rapid, highway re-charging stations will have to be much larger than current gas stations
Op is assuming the same structure as gas stations. No need for this. What if the car companies implemented a "charge crawl" feature, where a charging car would slowly inch down a track for a half hour while charging, attached to an overhead suspended cable? Actually, there's no need for that. Just have lots of parking, with each space with a charger. Most road trip rest stops take about 1/2 hour anyhow -- and that's when I'm in drill-sergeant mode with my passengers.
Problem 3: Gas stations are not generally in the neighbourhood of electricity generation stations.
Tesla is already building stations that get power from solar.
Problem 4: Re-charging will not work nearly as well when vehicle utilization goes up due to sharing
Consumers may not want battery swaps yet, but car-share companies might well want it.
These are not insurmountable problems, but they are expensive, or very time-consuming ones.
You also can't just run a power cord from a wall outlet to the street. You'll need to tear up the sidewalks, to connect the charging stations to the grid. In many places, power isn't underground, so you'll have to bring it down from the power lines to the underground - maybe through the buildings?
This quickly starts running to far more then $1000/charging station, and closer to $10,000/charging station.
This is what curbside parking looks like where I live:
https://www.google.com/maps/@47.6236671,-122.3252994,3a,73.2...
It would cost a fortune to wire that up. Better yet, if only half the streets in the area were wired up, due to the saturation of parking spaces, it would be close to worthless.
Replying to your edit: If you're installing them for a whole street at once, then the cost of bringing power down from a pole or digging under the sidewalk gets amortized across them all. We already hook every house up for water, gas, electricity, and communications. Providing power to every parking spot doesn't have to be particularly hard. It's not so easy you can ignore it, but nor is it a particularly big deal, not when looking at a timespan of decades.
Yes, you can slowly convert the whole area to support street-level chargers over the next few decades - but until you do, having chargers on ~20% of the streets would be next-to worthless. There is a dire shortage of street level parking in this neighborhood - if you limit your possible spots to the ones where chargers are available, it's quite unlikely that you'll be able to get a space.
There does seem to be a chicken-and-egg problem as you describe. Making the spots with chargers EV-only would mitigate that, although I'm sure it would be unpopular with the non-EV owners. It would help if cities got out of the business of subsidizing parking for their residents, but that ship sailed long ago.
I don't see that happening any time soon, and if it does the huge capital expenditure will have to be passed down to the consumers, reducing the economic attractiveness of electrical.
That may still sound like a lot, but the parking spot itself typically costs $2,000 or so, and you're saving on the cost of the gas pump that this charger helps to replace.
Yes, you have to account for the cost of charging infrastructure when looking at the total cost of an EV, but it doesn't greatly change the picture.
we have heating blocks for cars that park outside in north america. If you can install a street light, it's not that hard to install a curbside charger
But for long trips, what we'll like see (well, it makes the most sense anyway) is highway rest areas where there's recharging stations and eating areas in one complex. Most people can't go more than a few hours in a car without stopping to go to the bathroom or get something to eat and walk around anyway; it's just screwed up now because we have these different functions separated instead of putting them all in one place together.
This isn't a new idea by any means. There's several of these rest areas on the New Jersey Turnpike now. They have a gas station plus a mini-mall with gift shops, fast-food eateries, bathrooms, etc. It's basically like the "quick-stop" gas station, like Wawa, where you get gas and then go inside and get drinks, sandwiches made-to-order, use the bathroom, etc., except at the Turnpike rest areas, you have the choice of several different shops to go to, all in the same building.
So in a future where many people are driving EVs that need 30 minutes to recharge, I predict we'll see more of these kinds of rest stops, catering specifically to people taking road trips that are beyond the range of a standard EV that gets charged at home.
2 is a problem, but not an insurmountable one. Replacing batteries is something Tesla played with for a while but ultimately abandoned. Super Chargers charge a car in far less than an hour. There are probably other interesting solutions out there. These are all fixes for problem 4 as well.
Problem 3 and 5 seem like the same problem - we need to build more infrastructure as we build more cars.
6 is a non-issue for many people. I drive 15km to work every day, and then 15km home. I'd be happy with a car with a 100 mile range, to be honest.
7 is an interesting one, because most gas cars actually don't allow you to tow a trailer. My Honda Fit stated in the manual that towing a trailer would void all warranties. My Hyundai Sonata says "Towing with this vehicle is not recommended." Lots of larger cars that you think would be able to tow something can't, usually due to undersized cooling for the automatic transmission. Also, adding a trailer to an EV will hurt the range, but adding a trailer to a gas powered car hurts the range too; you just don't care because it's easy to refuel more frequently. See problems 2 and 4.
Problem 8: Service. Yeah. Xerox said they had nothing to worry about when it came to Japanese companies producing cheaper photocopiers, because none of them could match Xerox's humongous service infrastructure. You couldn't get a Canon tech down to your company to fix your Canon photocopier. Who makes your photocopier?
And problem 9 seems like a non-issue to me.
You should cycle if that's an option where you live. That's not a distance that I would consider taking the car for, but then again, nl has excellent bicycle infrastructure.
One of my family members does 30 km to work and back again in the evening, it takes him about an hour but he's in top shape and there are no hills.
Here in WA state the large majority comes from Hydro so an EV is much greener than traditional forms of transportation.
EVs will be very good for places with wind power as they can easily tailor the load to what is being produced so you don't have any more cases where the price of electricity goes negative.
My house has a 100A 240V service which is barely adequate as it is. I’m sure it could handle a single EV if I charge it overnight, but what happens when the rest of my family switches to EVs?
If I remember correctly, a charger for a Tesla requires a 50A 240V dedicated circuit, which would be half the capacity for my entire house just for a single car. Additionally, many homes don’t have such a circuit, so one would need to be installed.
This can be easily solved by upgrading my service, but that’s another cost.
In the end, it’s not a show stopper, but it’s certainly another hurdle that will cause a slowdown in adoption rates.
Perhaps codes should be passed which require the garage of new homes to have such circuits installed by default
The other option is leased batteries which solves a whole host of problems. It would probably cost a bit more, but you would never need to worry about the state of your battery pack. This would require standardisation though, unless everyone drives a Tesla.
In addition to that, home charging is only an issue if everyone decides to do a full charge every single night, which is unlikely. Most people will only need a daily quarter or half charge, city drivers much less.
Even if electricity doubled or tripled in price to compensate for the grid upgrade, it would still be cheaper than gas (at least in this country).
The tone of this article seems to think we will be stuck with current levels of technology.
Some future possibilities with in 20-30 years:
* Battery capacity doubling, tripling, or more.
* Widespread solar panel use for recharging at home (maybe they even come with solar panels as an upgrade?)
* Solar panels integrated into the car itself for continuous trickle charging (on the rooftop, for instance)
* Companies offering free charging while patronizing their retail locations (ala free Wifi)
* Parking lot charging via installed solar panels
Those are just the first few I could think of off the top of my head. I know there will be others as time goes by.
http://www.energyadvocate.com/batts.htm
Good news: metal-air batteries can achieve close to gas efficiencies! If we can only build an efficient portable reactor, and then an efficient fungible way to refuel with metal.
Problem 1: Transportation will load the grid and generating capacity in rather nasty ways
But not in specific times of the day, as A/C does. Granted, we're talking about much more power.
Problem 2: Rapid charging is actually not so rapid [...]
Yet.
Problem 4: Re-charging will not work nearly as well when vehicle utilization goes up due to sharing
If sharing makes usage of a vehicle go up to ~100%, it will only be a matter of having a few more vehicles. If a vehicle spends even 10% of its time recharging, we'll just need ~10% more shared vehicles. This only drives up production by 10%.
Problem 5: We don’t actually have all this infrastructure yet
Yet. The technology won't be too convenient for the next few years.
Problem 6: Range
That would make adoption easier in more densely populated regions.
Problem 7: Trailers
That's a problem for a small percentage of the population (at least here in Europe).
Load demand will be solved with local and utility scale energy storage, something which is occurring already in Hawaii where solar is so widely deployed that utilities have placed a moratorium on storage-less solar deployments because they can't handle the demand changes when a cloud rolls through town.
The issue with our electric grid is recognized at the highest levels of our nation. President Obama brought this up largely unprompted during his recent interview with Destin Sandlin.
Destin: "These huge technological projects that you're talking about, stuff America builds with our hands; I'm thinking of the Hoover Dam, the Eisenhower interstate system, Kennedy launched Apollo... Am I gonna to see that, ever again, in my generation?"
Obama: "I would like to see it - you know - in that order for us to do that, it requires a common vision of some of these big projects - now, I'll give you an example of an area where we should be investing, and that is creating a smart grid. This is something I've been interested in for a while. The way we link up energy is hugely inefficient in this country ... but the basic electricity grid that we have wastes huge amounts of energy."
This leaves us with only the range/changing issues which will both resolve as battery tech improves. Either of increased range or faster charging batteries will help, and we are seeing both. The demand for the Tesla proves we are already at parity.
Electric cars are charged at home most of the time. Let's assume that it takes 10x as long to charge a car at a supercharger compared to filling it with gas. (3 vs 30 minutes). But if you charge at home 90% of the time, then refueling stations can be the exact same size. And I'm fairly sure that people will be charging at home or at work much more than 90% of the time -- it's probably closer to 99%.
Given that you need invest a couple of 1000$ to install a charger (per parking slot) and also limit yourself to one type of EV (there are competing standards) and also your Employer ("Destination") needs to do the same…
So we're down to a irregular usage of vehicles, like car rental, car sharing or uber, all of which need to be flexible. EVs are not the right thing.
The only useful EV usage I can come up with is for commercial usages in pre-defined distances/routes. E.g. last mile delivery operated in a pool that justify setting up a central maintenance location, battery chargers/or swapping systems and more or less fixed usage time (=> loading batteries/servicing cars during the night or via spare cars)
Fast DC charging has a bit of a standards war going on. There's CCS, CHAdeMO, and Tesla Supercharger, which are all mutually incompatible. But for routine AC charging, you can install one charger and work with every car.
Grid saturation: smart charging to flatten the demand curve (overnight), daylight charging with more chargers in parking spaces at the office, west-facing solar panels and grid storage to smooth the duck curve.
Lack of chargers on the highway: increase in charging speed (15 minutes breaks are recommended after 2h of driving), increased battery range, platooning with autopilot can save 15% of energy [0], very low cost of expanding supercharger networks, auto-pilot to tolerate longer drive, auto-park to accept longer pauses, battery swapping
Energy sources far from charging stations: don't underestimate the predominance of home charging; south-facing solar panels and wind turbines along highways; grid storage; battery swapping
Car sharing: battery swapping again; autonomous fleets to dispatch charged car and auto-park cars (with snake-like charger to auto-plug)
Infrastructure investment: large public program for distributed generation with solar panels and grid storage
Range anxiety: 250 miles might be the average range for EV in 2020, supercharging and battery swapping to the rescue
Trailers: battery swapping again, and battery integrated in the trailer (might turn into a backup battery once at home)
Lack of servcie: EVs require far less maintenance than ICE, Musk intend to make a 1-million miles powertrain and reuse battery for grid storage; also industry-wide standardization
Tax break: they will somehow be extended to balance the externalities of fossil fuels (health, environment); EV will reach cost-parity very soon too.
The article also can't seem to make up its mind about whether EVs are suitable for long distance travel. It talks about how highway charging stations will have to be much larger than gas stations because charging takes longer. Then a few points down, it says that range and recharging time are incompatible with charging while traveling. Which is it? If it's incompatible, then you don't need highway charging stations in the first place....
Seems like the first reaction of most people here is to debate that problems exist in the first place.
I think it's terrific that there is diversity in the energy base for transportation. This is very healthy for the economy and for the country in general.
While it's true, that these new technologies may require adjustments, sometimes these adjustments can be overstated.
The actual energy usage for many appliances and industry is going down. LED light bulbs and other technologies are lowering the load to the grid. It's not a simple equation. It's a very complex equation and I don't think anyone has spent the time to factor that. At least I have not seen any studies on that.
This electric vehicle movement is not just about electric cars. People are rethinking their transportation. That's very healthy. It would be great if we continue to improve mass transit in America, so that less vehicles of all types are needed. I think many Americans would like to see that.
We're still also in the very early stages of electric vehicle's engineering. It's not a good idea to extrapolate out into the future based upon the technology of today. It's likely these electric vehicles become even more efficient in the future. As we see more volume in the industry, third-party players will also come in with unique ideas and improvements.
This mix of electric and internal combustion is really exciting. I think it's terrific that people are being lured from internal combustion to electric vehicles. The whole system seems to be going in a good direction. I don't agree with the naysayers. The outlook looks very promising.
These electric vehicles continued to sell even though the price of fuel for internal combustion's has fallen. The price of electricity is much more stable than the price of gasoline. This may also help people in making their decisions.
I suspect in the future we will see families with both electric cars and internal combustion. It will not be either or.
- gas stations and car dealers to go bankrupt
- price for maintenance and spare parts to jump
- investment in oil extraction to drop (as demand for oil decreases)
- gas prices to increase at the pump, due to diseconomies of scale within the oil industry and carbon tax
This could quickly translate into a vicious circle, and make ICE as luxurious as horse riding.
- spare parts: assuming you're talking about spare parts for the new EVs and not the old gas cars, I don't see why. They'll still need spare parts for crash repair, mechanical wear-out, etc. There's more to a car than the propulsion unit, and things will still need to be repaired. It'll be the same supply-and-demand we have now.
- maintenance: maybe. With less overall maintenance being necessary, there might be fewer mechanics and prices could then be higher. But it's easy to do non-engine-related maintenance on cars anyway, and they still need their tires changed, brake pads replaced (though not as much), etc. Tire shops won't see any change at all, I'm sure.
- car dealers: I don't know about this. People still have to buy cars somewhere, and while they might keep EVs a little longer, people usually replace cars now because the interior is getting old and nasty, the paint looks bad and repaints are expensive, it has dents and dings, new models look nice and have fancier electronics, etc. They could go to buying directly from dealers a la Tesla, but that's really orthogonal to gas vs. EV.
- gas stations: small local ones, yes. Interstate rest stops, no. We'll see more large rest stops with charging stations and restaurants all in one complex, so people can recharge for an hour while going to the bathroom and eating lunch/dinner on their road trip. We already have stuff like this, like on the NJ Turnpike. We'll probably also see other businesses integrating food and recharging in one spot: sit-down restaurants that are popular with travelers will likely add recharging facilities, and will advertise this (you'll see a billboard on the highway that says "next exit: Cracker Barrel now with 30 charging stations!").
For me, this is the "faster-horse" of transportation.
I want more radical changes towards walkable cities with more space for people and less space for vehicles. Roads take up an insane amount of space, and self-driving electric cars don't make things much better.
The car should be more like a family appliance used in weekends for holiday trips.

http://seguingazette.com/news/article_6dd61114-989d-11e1-b79...
First, EV batteries typically have active thermal management. Heat kills lithium ion batteries. When you charge your laptop, the battery gets hot, and this accelerates degradation. When you charge your car, the cooling system engages and keeps the battery at the optimal temperature. (The LEAF doesn't have an active cooling system for its battery. It also suffers much worse battery degradation than other EVs. Coincidence?)
Second, EV batteries are somewhat de-rated from their full capacity. Lithium ion batteries don't like spending time at the ends of their capacity. They want to live in the middle, not be fully charged or fully discharged. Laptop and phone makers tend to view their products as short-lived, disposable items, so they'll optimize for maximum running time on the battery by charging to 100% and draining to 0%, at the cost of battery longevity. A car will wall off some of the capacity so that when you're at 100%, you're really at, say, 90%, and when you're at 0% you're really at, say, 10%. At least some of these cars take it further and let you limit the maximum charge so you only use what you need. For example, I normally charge my Tesla to 90%, which is all I need for 99% of my driving. When I need that last little bit, I can charge it all the way to 100%.
Third, a large portion of degradation comes from the number of actual cycles you use, and deeper cycles are worse. A typical battery might last 300 100%-0% cycles before it degrades beyond usability. If you only use 50% of the capacity each time, then it might last 800 cycles. (Very rough number, totally pulled out of my nether regions, but you get the idea.) Long-range EVs are typically not driven to the limits of their range every day, so the batteries are treated well. Most days, my car might go from 90% to 80%, then get charged back to 90%. My phone, by comparison, goes from 100% to around 20% and back to 100% each day, which degrades the battery far more.
And when they're no good for that they're recyclable. Although currently it's cheaper to dig lithium out of the ground than reclaim it there's other stuff (cobalt particularly) that is reclaimed.
While they may share some aspects, the two were designed for dramatically different a) price points, and b) use cases.
As to points about the grid: The electric companies already manage unexpected peeks/valleys using several techniques. Interruptable power used to cut people's AC off in the summer when the grid is suffering by offering participants a steep discount in electric rates will likely see its first expansion into recharging ports. Off-peek/On-peek rates will change. Even surcharges for vehicle owners charging at certain times could be implemented -- all before the first changes to the grid take place.
Refueling: This fell victim to thinking of EVs as having the same limitations as ICEs. With the current crop of EVs, 99.95% of my travel would eliminate the need for a refueling station. I can charge at home and a look around my area, it's easier to find an EV charging parking space than it is to find someone driving an EV (Metro Detroit). More of these will appear -- the incentive to install these at retail locations is that you'll potentially increase your traffic and those who are there "just to refuel" will be there until they're sufficiently charged giving you ample time to make a few sales in the process. Cities are adding them as well and it's probable that this will become another revenue generator by having the car owner pay a rate above the electric rate/maintenance rate. For long-haul travel, these stations will now have something they never had before: a captive audience stuck there for the duration of the charge and their incentives will be similar to retail locations adding "EV parking spots"
The remaining problems fall under the category of "EVs are new and not as common as ICEs." Service stations will become more familiar with the products as more of them appear on the road. Add in self-driving, which seems to be growing just behind EVs, and you end up with a model where disabled passengers can be met with a new "rental" while their vehicle is towed to a location that can service them.
Because of a simple change to the fuel and engine, EVs don't suffer from some of the pain points of ICEs and require us to think about the similar problems that they share with ICE vehicles very differently.
For longer trips, you still need mass transit or perhaps car pooling services of some sort. But for commuter trips, I think electric bikes or trikes will absolutely replace cars in the near future.
Just some food for thought. Most neighborhoods simply are not wired for overnight charging of a significant number of EVs. I would expect EV interconnect fees or time sensitive tierd electric consumption independent of your net metering deal.
Or hyper-local generating capacity based on natural gas...?
It didn't quite work out as planned:
https://en.wikipedia.org/wiki/Better_Place
http://www.fastcompany.com/3028159/a-broken-place-better-pla...
One day, I guess.
> Problem 1: Transportation will load the grid and generating capacity in rather nasty ways
Electric cars are not a _complete_ solution on their own. They are _part_ of the solution, along side more renewable power sources like solar and wind. I drive an electric car and I charge it almost exclusively with solar panels at a local free charging station provided by the Tennessee Valley Authority. (I live in Chattanooga, TN.)
Also, as for putting load on the electric grid, electric cars actually help with that. Many can be configured to feed power back into the grid, and as a result, they can balance out the grid load throughout the day with their batteries.
> Problem 2: Rapid charging is actually not so rapid, highway re-charging stations will have to be much larger than current gas stations
Shift your thinking! Electric cars won't be charged at gas stations like gas cars of the past. Most electric drivers charge at home in their own garages or driveways. I have neither, but I still manage to charge my car in street parking with an extension cord, an exterior wall outlet, and a few of those little safety mat things so strangers don't trip over my cord.
Charging stations will still be important for cross-country trips, but the average driver doesn't travel that far often enough for it to clog up charging stations across the country.
> Problem 3: Gas stations are not generally in the neighbourhood of electricity generation stations.
See above.
> Problem 4: Re-charging will not work nearly as well when vehicle utilization goes up due to sharing
See above.
> Problem 5: We don’t actually have all this infrastructure yet
Well, duh. That's why we need to build it. That's not an issue with electric cars themselves. That's a problem with our infrastructure that we need to fix.
> Problem 6: Range
This is something we need to work on, but it's not as big of a problem as people realize. More than 90% of US drivers drive far less than 100 miles per day. The few times I do need to travel farther than that, it's actually kind of relaxing to stop at a mall or restaurant with a charger, plug in, and have a 30 minute lunch while I charge.
> Problem 7: Trailers
Really? This is problem for most drivers? This is a niche problem for the few people that actually need to haul trailers. So those people can just use regular cars.
> Problem 8: Service
I drive a Nissan Leaf, and I am very active in the Leaf driver community. I have never heard of a Leaf having major maintenance problems. Chevy Volt's are known for having some issues, but in my opinion, that's your fault for buying something from GM.
> Problem 9: Tax Breaks
How is this a problem? Tax breaks will eventually go away? So what? The whole idea is to make these cars cheaper now until manufacturing gets cheaper and the prices start to go down on their own. This is really grasping at straws.
Shift your thinking! Electric cars won't be charged at gas stations like gas cars of the past. Most electric drivers charge at home in their own garages or driveways. I have neither, but I still manage to charge my car in street parking with an extension cord, an exterior wall outlet, and a few of those little safety mat things so strangers don't trip over my cord.
-> I agree to an extent, however, I think you over estimate the discipline of the average person with respect to them always remembering to charge their car at night. The time it takes to recharge an EV to a significant capacity is still too long for people to easily transition, not to mention the massive current demands that would be required for such a quick charge. In an ideal world, people would plug their EV into an outlet every night when they come home from work, but we all know that the average person isn't as deterministic as that. How many people wake up in the morning and realize that they forgot to plug their cell phone in at night? This is why there's such a push for rapid charging technology in those devices.
In order for people to easily make the switch, I think we would need vehicles capable of charging to a ~100 mile capacity in under 5 minutes; similar to how long a refill for a gas vehicle takes. I’m not up to date on the latest EV news, so maybe we’re already there.
Nonetheless, I find myself many times in the morning on my way to work, glancing down at the gas gauge, realizing that I forgot to refill last night. This forces me to make a quick stop on my way to refill, which only adds about 8 minutes to my total commute. Waiting at an EV charging station for 30 minutes would require a significant change in my lifestyle.
People like the average HN user are generally responsible enough to make appropriate accommodations, but my 68 year old father wouldn’t go through the hassle.
Another hurdle I see with overnight charging is the mess it would cause in cities like Philadelphia where you aren’t guaranteed to end up in the same parking spot every time. The people there can’t even handle shoveling out a parking spot without shooting each other, so I expect a few issues when there are extension cords in front of everyone’s house and you need your specific spot to charge your car. This could easily be solved with a universal charging infrastructure that includes chargers every 10 feet, but that infrastructure will only come when adoption reaches a certain rate where the _massive_ costs can be justified. This is the obvious catch 22.
Of course, these issues will slowly go away as EVs become a part of everyday life, but I’m specifically talking about the transition period.
It's pretty clear to me that I will be unlikely to ever own a car again. But this Tesla is the one I expect will be my self-driving taxi for many years to come and before the decade is out.
This would cancel out the ecological benefits of running an EV, even if the power station had more efficiency than a combustion engine.
The biggest canard is "If everybody switched to EVs tomorrow our power grid couldn't handle!"
Yes and if everyone went outside right now and pooped in the street we'd all drown in shit. Neither scenario is actually going to happen.
The reality is that EVs are far, far more efficient than ICE vehicles. Not only that, they don't create all the secondary waste products like used engine oil, coolant, etc. LiOn batteries are highly recyclable.
Adoption of EVs has been and will continue to be gradual, and our power grid will continue to expand to handle the load.
Just as a personal anecdote, I currently have a Nissan LEAF and when we got it we expected our power usage to jump dramatically. It did not. But our savings on fuel (not to mention maintenance) did jump. Even with current cheap gas prices, it's still way cheaper to drive the LEAF than our 30mpg CR-V.
Nailed it.
Just wait though, I said the exact same thing above and the author told me to "fuck off", and the HN hivemind is heavily down-modding any comments critical of this guy.
Any more unsubstantiated and bull-shit accusations you'd care to make?
The population of New York City was 1.5 million people in 1890. It's 8.1 million today.
There are only two ecologically sustainable ways of increasing generating capacity: solar and nuclear. Both will be deployed on massive scale.
The new atomic age awaits us!
The implication that simple lifestyle changes would enable most American's to do away with their automobiles is utterly ridiculous and demonstrates complete ignorance to the suburban environment surrounding all cities in the United States and other parts of America. If a large number of people did vacate the suburbs for the city, this would create a housing market crash in the suburbs that would draw just as many people out of the cities into the suburbs. Without revising land use policies in the United States, there's no way to support this. Just look at gun control polices if you need any more evidence of how ridiculous this notion is.
His argument that everyone will be charging their EVs at peak times and will overload the grid is ridiculous and completely ignores the fact that most people today are aware of peak vs off peak electricity rates and specifically charge their EVs during off peak hours to avoid paying higher rates. This is analogous to driving a few extra miles to save $.05/gallon on gas. People are cheap and won't do that for financial reasons.
He then goes on to make a number of points about the lack of charging infrastructure that would make EVs unfeasible but these completely ignore his first assertion that most people will be charging at home. More than 90%* of commuters have a commute of less than 36 miles one-way which means that only 2 EVs on market (i.e. Mitsubishi i-MiEV, Smart Electric Drive) would be unable to cover their daily commute. Which means that in most cases the need for charging stations would be radically diminished. Another thing to consider is that petrol stations exist in their current form because of regulator requirements around the storage of hazardous materials (i.e. petroleum products). There's no such restrictions around EV charging stations and in a world with 90%+ EVs it's not hard to imagine every parking spot having a charge station.
The assertion about vehicle maintenance being an issue is also equally ridiculous. He states that most EV systems will be unservicable at the average garage which is debatable. The power train will probably remain unserviceable but an EV's powertrain is significantly more reliable than your typical ICE. All of the other major and minor systems (i.e. drivetrain, environmental, braking, etc) in an EV are similar to those of an ICE vehicle and thus serviceable at a regular garage. Considering that most EVs will be daily commuters, the likelihood that you'll find yourself with a powertrain failure in a location where your EV can't be serviced is also highly unlikely.

Prob 1 is solved by the death of 9-5 full time work. Its just not relevant to most of the population anymore. The problems of deploying EVs in Levvitown in 1949 are not relevant to 2016+. Also "smart" grid connected battery chargers are more advanced than the typical 1949 "battery rectifier".
Prob 2 insists that what he calls fast charging would in the industry be called medium-slow charging. Also it strawdogs that a significant fraction of people will every require it and be willing to pay the likely "just under the cost of a SUV's tank of gas" they'll charge as a convenience fee. Finally he misses how rest stops along interstates actually work in recreational states like where I live... its just not a practical issue.
Prob 4 overestimates the popularity of sharing. Its kind of like wife sharing, many talk and think about it, only a tiny fraction do it, but its not unusually popular, nor growing, and not a significant population issue. Among certain extremely small subcultures its popular, but much like rurals who commute over 100 miles per trip, they're just going to be ignored and frozen out of the EV market. They can buy hybrids and the remaining 95% of the market will buy EVs. For a gas analogy, the fact that my micro-sub-compact can't tow a 37 foot sailboat turns out not to have eliminated its sales from the market, no matter how important that ability is for owners of 37 foot sailboats, or at least those who aspire.
Prob 5 carefully ignores historical infrastructure growth examples, population shifts in the USA, suburban sprawl, and ignores the slow rate of ramping up EV production. Basically, we have decades of experience building new infrastructure faster than we can possibly build new EV assembly lines. NIMBY areas will suffer, nothing new there, but I couldn't care less about them, and a little suffering might improve their views a bit.
Prob 7 is the great towing conspiracy (google it) where existing gas mfgrs try to protect suv and truck sales by pretending that magically only trucks can tow in the USA. Its pretty crazy, my (gas) car is rated to tow 2000 pounds in Canada and of course 0 in the USA, because they have to protect truck / suv sales. It is true, if you need to tow in the USA you already must buy a truck to do it legally while insured. So not being able to tow with a commuter EV isn't a downgrade from commuter gas cars that already are legally rated as zero (in the USA). Further when I do need to tow, its usually 3 miles to home depot or 5 miles to the lake, not crossing the Rockies in a blizzard.
Prob 8 is absolutely comical, like an anti-hybrid troll from over a decade ago or an anti-import troll from when I was a kid. When that tired argument is the best they can roll out...
Overall its mostly problems that exist primarily in the mind of opponents where 99% of the population won't care no matter how many times the talking points are repeated, much like the tired saw that no EV range is acceptable other than (max_currently_available) + 50 miles for all available ranges from 10 miles (homemade lead acid conversions) on up.
1) Grid strain - By the time EV cars are popular enough for this to be an issue, installed home solar capacity is likely to be large enough that it is likely to look more like this:
2 kW worth of solar panels
1 Battery Pack (possibly interchangeable with the car)
Battery pack is drained when you get home and charge the car.
This will cost you ~$15,000 which is cheaper than the car and will last ~20 years (minus the battery pack which you'll need to replace every 5-10 years). This might go as low as $7.5k depending on technology improvements, incentives, sunny days, etc.
On cloudy days, it'll just charge from the grid over 6-8 hours while people are at work.
You'll want a system like this with 1+ EVs simply because you'll be using enough power it'll start making financial sense in most of the US.
2) EVs are primarily commuter cars so as long as their battery back lasts long enough to return home, it'll work. The rare instances where you'll need to recharge at a station will largely be irrelevant for day-to-day activity. Cars used for long distances ( 180+ miles ) regularly will likely remain hybrids or fossil fuel for decade(s).4) Sharing will largely also be a non-issue since even when utilization goes up, we are talking ~3 hours of drive time to ~1 hour of charge time. You'd need to have greater than 50% utilization before charge time is likely to create issues. Similarly, as tech improves, that ratio will improve.
6) This is largely solved by the fact EVs are primarily going to be local commuter cars. Replacing commuter cars, in and of itself, is a worthy goal as it improves city air quality substantially which is linked to problems like asthma and cancer. I honestly don't care if long distance trucks which largely are spending their time in rural areas remain fossil fueled. I care about city air quality.
