Plug-in hybrids are the perfect car for most people - I won't repeat myself but a previous post on the topic: https://news.ycombinator.com/item?id=38863491
Literally none of the problems pointed out in this article apply to people with plugins, and you still get 95% of the benefit of having an EV.
Hybrids by the way are not new at all. They have been used in shipping for ages in situations where the electric load was about the same or higher as the mechanical load, which happens in cruise ships for example. It worked in ships because of the high electric load and because weight doesn’t matter too much. This all doesn’t hold for cars. If it would have worked great, we would all be driving Priuses by now.
Good news, millions are! Millions more drive non-Prius hybrids, because people thought the shape of a car that cut through the air more efficiently than most was "unmanly"
That's a common refrain, but in my personal experience I don't think it really holds water because of the additional savings you get:
1. The battery can be much, much smaller. This results in huge savings in cost, weight and environmental impact that offsets a lot of the cost of needing a gas engine.
2. You will end up utilizing much more of the battery. That is, the only reason you need a big battery in EVs in the first place is those thoughts of "what about longer trips", even if you only take longer trips 3% of the time. Plus, I would frequently drive my Volt's EV charge to near zero or zero (but still only use something like 0.1 gallons of gas), but with my current EV I never take it below ~30 miles of charge for fear of getting stranded.
Your other examples don't really hold for plug-in hybrid vehicles. I think the big reason they were largely passed over in the marketplace is they were often "bolted on" to existing ICE models, so people saw them as just an additional expense with marginal benefit. Perhaps a good marketing guru will market them instead as "All the best parts of an EV, but with all the things that you hate/that scare you are fixed!"
But, to be clear, a plugin hybrid is lighter than a comparable all-electric car because the battery is so much smaller. E.g. a Chevy Volt weighs about 3500 lbs vs. about 3800-4000 lbs for a Model 3.
2. so you have much more parts, more expensive to be produced and assembled just to wear out an expensive component quickly, UAU, that's a nice ideas... For the car OEMs...
Is this suggesting there is a connection between "led by Musk" and "made a hug mistake".
But, good news! EVs with 24/7 heat pumps keeping the batteries alive are a thing and work out pretty well in within-the-Arctic-circle locations such as Greenland, where previously "keep your diesel engine running at all times during winter to prevent the fuel from freezing" was the norm.
So, no, keeping the planet alive and getting to the Supermarket or your Job or your Dying Grandparents are not necessarily mutually exclusive, even in cold climates! Exclusions apply, not everyone may qualify for the technological advances mentioned, see dealer for details.
That's not true. There are battery recycling plants going bankrupt because the expected surge of dead EV's didn't materialize. EV's are staying on the road longer than expected, and the batteries are being reused rather than recycled or thrown out.
This is a very real problem - especially because, imagine the heat pumps you just mentioned. You go to the grocery store. There's no heat pump at the grocery store. You are quite limited in your travel by how long you need to be at your destination for - which sucks.
I mean, real scenario here: It's the Yukon, it's -30C outside in January. You run in for groceries and the battery is low. You get haggled a bit. You come back outside, your battery is dead because it's cold. You can't run your heat pump either, because the battery is dead. You can't use, say, a fire or a blowtorch either. Time for hundreds of feet of extension cords.
Most people won’t drive when it’s this cold anyway
And, because it is running, your batteries will not reach a temperature where they start degrading. And, yes, this means your driving range is reduced slightly, but because heat pumps are so efficient, and because the alternative is, as you so eloquently observe, "car is dead", it's... sort-of worth it?
And the wonderful thing is: this works in both extreme cold and extreme heat, because heat pumps are reversible! So, for a little bit of battery power/range reduction (let's call it 20%?), you keep your EV (and the planet!) alive a little while longer.
Now, I don't have any experience with 'the Yukon', but I can tell you from personal experience that: a Volkswagen Transporter, used for staff and goods movement in Greenland (so, short distances only: all serious travel is done by plane or boat), that in its fossil-powered incarnation would need to run 24/7 on diesel for a good 90 days a year, works perfectly fine year-round in its heat-pump-upgraded EV life.

My expectation was also that switching to electric cars would involve some sacrifice but for my use cases it has been net more convenient.
For daily commuting I plug in at the office garage where they have dozens of L1 and about twenty L2 chargers. This has been more convenient than remembering to stop at a gas pump a couple times a month.
I initially kept a gasolene car for long trips because I assumed it would be inconvenient to schedule a ~30m stop every ~4 hours or so. In practice it turns out I need to stop about that frequently for family members to stretch, use the restroom, and grab a bite, etc. The major difference has been that it constrains where we stop rather than when we stop.
However, if you are regularly doing 5+ hour trips in rural or remote areas, then a gasolene or diesel vehicle is a more convenient choice. As they build out a more comprehensive charging infrastructure the difference may lessen.
I cannot speak to reliability as we've only had them for a year now.
1. The EV always starts. If it's below -20, our gasoline car may not.
2. The battery is always charged in the morning. OTOH the gasoline car is only filled sporadically. In the winter I try and ensure there's at least half a tank for safety reasons, but sometimes it does get as low as a quarter tank. Even with cold loss, an EV with a full battery has far more range than a gasoline car with a quarter tank.
3. The EV can be preheated in the garage without killing people.
4. An EV battery has enough capacity to run the seat warmers for a month, keeping people alive in an emergency. A gasoline car can only idle for about 24 hours.
5. That's if you keep your exhaust clear. I know people who didn't, and died.
6. A EV that's plugged in, but not inside can be kept warm.
7. Our EV handles a lot better on snow and ice than the gasoline car. Perhaps it's because of weight, perhaps it's because it can do traction control with the motor rather than using the brakes.
When I was planning a trip to Tahoe, during inclement weather, I figured my new RAV4 Prime (a hybrid) would be perfect. I'd drive the whole way on gas and keep the battery fully charged; if I got stuck on Donner Pass, I think the battery can keep the main compartment at a reasonable temperature all night without running the ICE. Fortunately that never came up but it was an interesting thought at a time when folks were getting stuck on Donner for 10+ hours.
About point 4) well... My car suck 20A@400V to run the heating, definitively can't last even few days.
About 6) all BEVs I know do not offer real "keep the battery heated as long as it's cold enough" function, some decide randomly to try heating the battery, but not much is left in users hands. One of the many things those who design ALL modern software do have to learn and refuse: user control first, automation only at a subsequent level...
About 7) well, no. Electric motors spin brutally, witch MIGHT be useful under certain conditions but it's also useful to lose grip in many others, and it's also an issue when parking in tight places...
6) Yah, it's pretty magical, which can be annoying all right. It's the "I want to leave at time X" function on ours.
7) Interesting; not my experience. I'm comparing a Tesla & a Mazda. Top spec winter tires on both. 510 N-m of torque so it'll easily spin if you push too hard on the accelerator, but I find it responds much better to the standard winter driving technique of not too much accelerator...
6) some example: I have an EVC300400300 witch offer also a bad integration with my p.v. (bad, because badly designed by Victron), I do not count how many times my car refuse to charge or by EVC refuse to allow charge because of crappy communications between the two and ZERO control on my side. I have HA who handle as much as I can in the actual crappy state of crapIoT but nothing I can do with anything not made to be integrated. Cars actually are one not made to be integrated, even if they offer also V2L, crapplications for remote control and so on. The are just designed as a rolling data collection device, controlled by the OEM not the formal owner. To came back on topic I simply can't makes my car heat the battery when I want it heated to use it in the early morning, there is no way to do so. The car decide autonomously when to heat and the EVC decide autonomously if allow it or not, so the resulting behavior is NOT MUCH BASED ON ACTUAL TEMP but on random interaction behavior between two badly designed devices. That's is.
7) it's not a matter of mere horsepower or torque, with a mechanic gearbox I can dose the torque, with an EV I can not. It's the same when parking in tight places, arriving slowly to nearly kiss another vehicle bumper is easy with a mechanic gearbox, next to impossible with an electric motor. At least not if I can't both accelerate and break a little bit in absence of something better.
7. The torque an EV puts out is infinitely controllable. Give DC current to an AC motor and you get 0 torque. Give it full current with the appropriate waveforms and I get enough to spin the tires on dry pavement. And anything in between, fully controlled by the accelerator pedal.
Never once have I had to rock the EV back and forth to get it uphill out of my driveway when there's snow on top of ice, I just feather the accelerator. I have to do it quite regularly on my Mazda.
About torque: no doubt that an electric motor can dose, actually the car pedal sensitivity do not allow the same, specially on slippery or steep roads, at least that's my experience with my modest MG ZS and few others EVs I've tried. Of course, someone might add a "parking mode" to help, but who have done that so far?
For my everyday driving, you know, home->work->home, home->store->home, and the like, I NEVER have to think about range or recharging. For me, it is a much better experience than a gas car could provide. I pre-heat my car in the garage, have charging on auto, get in the car, and go. I never even have to scrape ice off the windshield when it's left outside because I'll turn on the heater 20 minutes before I plan on going.
As for reliability... Tesla's aren't well-known for reliability, but I'm still driving my 2014 car; it got a handful of warranty issues fixed, and since it's been out of warranty, I've only had to replace the 12v battery. This car is far less maintenance than any I've previously owned.
Case in point: during summer in Europe, assuming sunny weather, the 15-minute daytime spot price for electricity is generally negative due to the glut of PV supply. In other words: you can charge your car during the day and get paid for doing so. Then, at night, you feed back, like, 50% of your stored energy to the grid.
You get to drive to work in the morning just fine (where you can charge your battery again, for free-or-less), and the (very little) you got paid for half-discharging your car during the night definitely did contribute to lowering prices during that time as well...
Even if we did have EV charging available everywhere, excess of energy during times of peak production is the reason why energy might be cheap or free. As soon as you actually start utilizing that excess, the prices will stabilize around the average market rate.
* EV battery conditioning
* diesel anti-gel
* engine block heaters
Many machines don't like the cold.
I remember getting days off of school as a kid because too many of the school busses wouldn't start due to gelled diesel.

And Tesla should probably take inspiration from those, and power the battery heater from the charging station, so you don't get:
> The solution is to keep the battery warm, but the heat comes from the battery itself, so these stricken Tesla drivers are draining the battery just to be able to charge the battery, and we don't need to explain why that might be inefficient.
Even arctic grade diesel will gel at -45C.
EVs fare better in cold climates than ICE cars. They never fail to start. You don’t need a block heater. You can pre-warm them in your garage. You lose some range, that’s it.
The reason those chargers failed has nothing to do with batteries and does NOT reveal “cold hard truth” about EVs. Half the superchargers across chicago were disabled in unison - could have been due to grid stability reasons.
There are lots of good things about EVs in winter. I definitely like the ability to prewarm the cabin while it’s on the garage.
This article is about a specific problem which is you can't even charge the battery if it's cold enough. That seems like a pretty terrible failure mode that needs a solution.
The general range problem is simpler. Partly it's because the battery chemistry works less efficiently when it's cold. And partly it's because some of the battery is being diverted to heat the cabin. (Another surprise owning an EV; they're hard to heat! No big engine throwing off waste heat. It's no accident most high end EVs have resistive seat heaters.)
It's not rocket science. Thermodynamics, maybe, but not rocket science.
I've seen trucks parked in Iowa in the winter with a heater plugged so the fluids don't freeze (a power cord coming out of the hood).
Turns out extreme cold is bad.
Also this guy was driving something like 1100 km in -40 weather already - if you dont absolutely have to you shouldnt do it at all.
The rule of thumb is that for every 10 degrees celsius increase, chemical reactions double in speed. (Conversely, drop that temperature by 10 degrees and the speed of your chemical reaction will be halved.)
In other words, drop the temperature of that battery by 20 degrees celsius and you quarter the amount of energy you can obtain per unit of time.
Yes you'd need a larger electric motor, but that feels like it should be less expensive than all of the traditional drivetrain components?
no idea if any cars use it. probably not since regenerative braking is one of EV's selling points.
I think if you add a small battery to recycle braking energy you get a https://en.wikipedia.org/wiki/Hybrid_vehicle_drivetrain#Seri... which is pretty rare for some reason https://www.greencarcongress.com/2023/01/20220114-mazda.html
But yeah it's your comment of "pretty rare for some reason" that made me think it was possibly not viable?
Not necessarily. We recently had a customer from the Yukon region in Canada. That customer is farther north of Saint Paul, Minnesota, than Saint Paul is north of Dallas, TX.
your example of someone that lives so far north that their coming hundreds of miles south still means they are further north than most people is proving what? nice story and all, but the point is a bit lost
Convince them to buy an EV. In an area with January average lows of -30C, and historic cold snaps that have sometimes reached as low as -60C.
Only in Texas do things have trouble working correctly when it gets down to 13F. Auto-spec parts are rated for -40C to +105C.
Generally in Minnesota the primary problem with (older) ICE vehicles where the battery is located toward the headlights instead of back toward the firewall is that a battery with low charge will have a cell or two freeze when it's kept outside on a -10F - 30F night facing into the northwest wind, then the engine doesn't start the following morning and the battery needs to be replaced. Very few vehicles have trouble in 13F weather, except maybe in Buffalo, NY when so much lake-effect snow falls that the vehicle can't even drive through it.
that's an absolute gem of a bullshit comment. congratulations. you made my day knowing that there are some morons roaming these parts.
Next iteration could skip batteries and plug electomotors directly into generator.
Some "supercharging" stations are powered by diesel generators. So this is not a joke!
Or maybe some sort of swappable unit for a car, it could contain batteries or small generator. At week I would drive at city on electricity, for holiday trips I would swap power unit for petrol!
Patience...
Trip was OK except for round abouts
Limp mode is one thing, disabling ABS just because no battery, even if alternator is putting out current, seems like a design flaw.
On X (formerly Twitter), conspiracy theories go around that journalists are out to get X because X is taking away readers and advertiser revenue. I'm not sure whether I believe that fully, but I do find it surprising that The Register calls X a "hellsite". Where has journalistic objectivity gone?
* No more third party clients.
* Can't see replies/parents when not logged in.
* Can't see chronological feed of accounts when not logged in.
* Ranking algorithm now favours paid users, not better responses.
Feels like the kind of changes that would happen if a PE firm acquired Twitter and tried to squeeze the userbase for every bit of revenue.
If you have to drive 1100 km in -40 for work and they don't provide you proper transportation, you should refuse or you should rent a non electric car. It's literally a danger to your life to do otherwise.
I see you are unfamiliar with The Register. They've always been snarky.

Twitter users have been affectionately calling Twitter "the hellsite" since long before the ascension of Naughty Old Mr Car. I think it may be via Tumblr, which was sometimes called that even earlier.
Per Google Trends usage of the term peaks, in the recent past, in late 2022 (I suspect due to people eulogising Twitter), and declines thereafter.
