I realize the offer is to a major US automaker which is much different but it just seems like a brilliant billionaire like Elon Musk and an amazing entrepreneur like Shai Agassi (who has raised $900MM+) could pull it off.
Edit: just to be clear, I support people sharing their chargers. But fast charging is overkill.
Anyone who has ever exchanged a propane cylinder for their backyard barbecue should understand why this is the only conceivable way to make electric vehicles work. I can't begin to imagine why I'm the only person who actually thinks that way.
Oh, come on. First World Problem: "My new pollution free cars fills at home, but on the few occasions that I have to go out of my way for energy it takes 10 minutes to refuel instead of 2."
You're ignoring the substantial problems that battery swapping introduces – it introduces issues of standardization, compatibility between cars, more moving parts, more weight, additional vehicle design constraints, and creates enormous inertia in battery technology. It constrains innovation. No company can come out with "The 2021 Leaf, now with 15% denser batteries!" without fragmenting the shared supply of battery packs.
I admire Shai Agassi's business model, everyone seems to be fixating on the battery swapping aspect. It's incidental. The real innovation there is using the cell-phone business model on electric cars.
Imho, an alternative solution with fewer drawbacks would be offering "on-shore" cooling by exchanging a fluid coolant through the charge connector. The charge-rate constraint isn't really the batteries, it's how fast you can cool the batteries. With offboard cooling you could charge a ~300 mile range EV in about 3 minutes without over-sized onboard cooling. You're also more likely to find a use for the waste heat offboard, e.g. melting ice or preheating water.
The down-sides of this system are small – any sufficiently high-current "cable" would already be mounted on a "weightless" articulation rig, or a robotic solution that plugs in automatically when you park (Shai Agassi has been working on this technology).
I.... I just don't know what to say to this.
Except maybe "Good luck."
Once battery capacities reach the point where you only have to charge it at night for a full day's drive, you've solved the problem and you don't need to swap.
And, while the price tag is high, the 300 mile claimed range of the highest trim Model S gets a substantial part of the way to that standard.
Perhaps that's true... once batteries get about 2x as good as they are now, owners of cars like the Tesla won't have to worry so much about whether there will be power available at their destination.
My impression is that the next 2x improvement in battery tech is pretty far over the horizon, though. Plus, we simply do not have the grid capacity to replace most Americans' automobiles with rechargeable EVs. Not even by charging them at night. Once 80% of the houses in your neighborhood plug in an 8-kw load at night, this inconvenient truth will become obvious enough.
Exchangeable batteries could be charged anywhere, anytime, not just where and when they are needed. That's a big win regardless of what happens with the core technology of power storage.
Modern batteries (LiFePO4) can be charged in 10-15 minutes. I know I'm going to want to walk around for 10-15 minutes after driving for 120 miles. Heck, that's even the recommendation to avoid DVT!
High range is one way to solve the problem. Fast-charge is another.
This is not a valid analogy.
Sure, you can. When's the last time the battery display on your laptop or cell phone lied to you? Battery monitoring tech has been reliable since the lead-acid days, and it's only gotten better over the past few years.
There'd be some redundancy in most cases anyway. A sports car might require two or three standard battery units, each of which would consist of numerous individually-monitored cells. An 18-wheeler might require thirty or forty of the same standard battery packages, or perhaps ten of a larger form factor (think 'AA' versus 'C' or 'D'). In both cases the vehicles would be able to limp on half-power or less, in the event of battery failures.
This objection is a complete non-starter, no pun intended.
Edit: By the way, those swappable battery modules are going to last a lot longer since they won't need to be fast-charged.
This is probably the kind of thing that would need to be done by international agreement, if it can be done at all.
I know what a fast-charger does, but you still don't need one at home. You need to sleep, remember?
Do you need a gas station in your garage?
> you're extending the infrastructure of places you can charge Teslas
At $25k/station you're going to need more than "the cause".
> if you monetize it ($15-20 for full, fast charge) then you're making money.
I assumed so. You'll still never make back what you put in.
Current prices are around $7 for a 30 minute charge. Of that, $2 is electricity. You'll also need to pay the electric company extra to have a bigger connection to the grid (>100A at 480V), which usually costs hundreds of $ per month.
Yes, you need sleep. Are the people that you're sharing your charger with going to sleep at your house?
Their goals are:
- High price low volume car.
- Medium price medium volume car.
- Low price high volume car.
They seem to be on their way.
Also the article claims he said 'It's going to be tough.' He has always been pretty straightforward with that. Check out any of his interviews.
Check out his interview after Falcon 1 failed http://www.wired.com/science/space/news/2008/08/musk_qa
An excerpt from that:
"Wired.com: At the end of the day you're still zero for three; you have so far failed to put a rocket into orbit.
Musk: We haven't gotten into orbit, true, but we've made considerable progress. If it's an all-or-nothing proposition then we've failed. But it's not all or nothing. We must get to orbit eventually, and we will. It might take us one, two or three more tries, but we will. We will make it work.
Wired.com: How do you maintain your optimism?
Musk: Do I sound optimistic?
Wired.com: Yeah, you always do.
Musk: Optimism, pessimism, fuck that; we're going to make it happen. As God is my bloody witness, I'm hell-bent on making it work."
For a discontinued car (or, a car made by a defunct company) to still be drivable, there needs to be a sufficiently large community of enthusiasts around it that have figured out how to fabricate the parts that are no longer available.
Now, this has certainly happened. Lots of cars from the 1920s and on are still on the road, and a cottage industry has sprung up around keeping them running. However, the defining feature of these cars is that a substantial amount were sold.
Getting parts made in the future for a very unusual and technologically advanced car like a Tesla if the company is no longer around is going to be very expensive indeed. It will cross from being a daily driver to being a project car, and the owner will need to be very dedicated to the project.
What fraction of the parts on a car do you think that a 3d printer can produce?
For example, they can't produce any of the electronics. They can't produce any of the load bearing parts. They can't produce any of the sheet metal.
> Heck I'd love for mandatory escrow of every component's 3D models
Lack of 3d models is rarely the problem. (In most cases, you can use an existing part as a template.)
Today? None, or next to none. In 5, 10, 20, 30 years?
As I pointed out, 3D models help with a minor problem, a problem that has other solutions. They can't make much difference.
I also expect the man whose other company sends stuff into space to be able to lead this one to overcoming those challenges.
The big open question (which Tesla doesn't want to set as the benchmark for success) is selling a mass-market car (the next one). I'm confident Tesla can do a 50-100k unit/yr high end product ($40-100k) on its own, eventually, but building a $20k car and shipping hundreds of thousands is a different matter.
To sell units beyond their first adopters they need to address key issues with electric cars (and I am all for EVs). What they need to do is license their technology to Ford and GM to get mass market appeal and to help build/develop EVs in the $20k range. As the article states, "It projects selling 20,000 cars next year, which is a relatively high number among luxury brands."
This is really what is going to happen: the will be acquired by a larger brand.
Actually this is quite low. BMW sells around 110K units a year in the US alone - http://online.wsj.com/mdc/public/page/2_3022-autosales.html
Although I do agree the best bet for the survival of the technology is to get bought by a larger brand.
I could be wrong about this, but I suspect the median selling price of a BMW in the U.S. is about $10,000 less than the cheapest Model S. Selling 20,000 cars that start at $50K would be a feat.
Great. So American taxpayers are essentially subsidizing luxury automobiles.
http://en.wikipedia.org/wiki/Government_incentives_for_plug-...
The tax credit isn't paying for people to get nice cars, it's paying for people to get electric cars.
What we're actually subsidizing is R&D on electric vehicles. The problems that Tesla is struggling with (battery longevity, battery cost, charging cycle times) are fundamental problems of all electric vehicles. If a government subsidy for their luxury vehicles helps them improve the state of the art even incrementally then it will be a huge win for the public.

The hard part starts when all that is past: when they build enough cars to have them sitting at dealerships, either being bought or not.
(For that matter, if they really want revenue, why not keep churning out the Roadster? Surely there would be a few thousand more people willing and able to buy one.)
The next six months are critical because it determines whether or not Tesla can be a profitable venture. Can they make a profit with full production? If they have any unforeseen expenditures they are screwed. If there are any recalls, they are screwed. However, I am pretty confident Tesla will be able to pull through given their track record.
The reason I appreciate tesla, is because it doesnt have all the legacy and baggage a traditional car manufacturer has, and thus they have the ability to try bold things. On top of it, they are doing it all in america.
The land and power are cheap, the wages are reasonable and there is not a lot of union activity.
All this depends on charge/discharge rate, temperature, etc. The Roadster's complicated battery system is required because they used LiCoO2 batteries. :\
PS: The real issue is it's not a smooth transition, but if you assume the 2nd battery pack is not worth it you get 250,000 miles including 1 replacement pack.
We should also consider the depreciation of components in a conventional car that the electric drivetrain replaces. They should depreciate faster because they are less efficient and must deal with the additional heat they dissipate. They require an intake and exhaust system, complicated transmission, pumps, valves, lubricants...
A Tesla with a failed battery is $20k away from being a useful vehicle. A depreciated Jaguar is a driveable vehicle.
And, even with a new battery, a 3-5 year-old Tesla isn't worth as much as a new Tesla (even if we ignore the likely advances in 3-5 years).

Also: lol at the price. I get why it's that expensive (tariff, taxes) but wow, I can't see them moving many.
