If a Model 3 LR is 75kwh, and this is roughly 3x the range, and that takes roughly 20 minutes to go 10-80% at a supercharger then can anyone tell me what kind of hardware would be required to charge a 225kwh battery in the same time? Is it remotely feasible to build at least 100,000 of those chargers all over the world? Sounds like each one would need a gigantic capacitor or flywheel on site.

Those chargers already exist. Tesla vehicles are limited by their 400v electrical system. Porsche already charges faster for longer via an 800v electrical system. You also have to remember even 10-80 throttles SIGNIFICANTLY over that window as the battery fills. The higher speeds will run for longer on a larger battery assuming it is designed with sufficient cooling - one of the features of solid state batteries is s…

That’s a good point. So an hour long charge vs 30 minute charge with a SS battery could mean a 200 mile difference vs with a current battery it could be like 50 miles or less difference.

The funny thing is that Toyota for years have said they had this technology in development, but they ended up purchasing the tech from another company.

In automotive the OEMs almost exclusively purchase from suppliers like this and develop very little actually in house directly. That said, they can be heavily involved in its development, like it sounds in this case. This is partly done for liability reasons (supplier takes the liability if this battery catches on fire, not Toyota)

I wish articles like this would standardise on W/kg or W/L. Range is meaningless when you don't know the pack size.

It's still quite meaningful. It's the distance you could allegedly drive without recharging.

Drive what though

…why? I get range anxiety is a thing. But no one needs that kind of range in a car. Why not make it 400mi/650km and save a ton of weight? The battery here gives double the range of an Accord. Who needs that? Less battery is less weight. That’s better for tires, roads, charge times, brakes, accidents, acceleration, drivability, cost, and probably more. 250mi is plenty. For most even less. But there’s a psychological f…

I drove across the country for the holidays a couple years ago because I planned to spend a few weeks there and didn’t want to rent a car the whole time at the destination. Plus we had our dog to tow around with us. If I only drove 400 miles a day, it’d have taken me 2 weeks to drive there and back. I have better things to do with my time and paid vacation than spend two weeks driving. No, this is not an every day/we…

However, also you should try to broaden your horizon. Not everyone lives in the US or Australia or Canada. Especially in Europe there‘s other countries and big cities that won‘t require thousands of kilometers to drive to. And of course, there‘s convenient public transport for long distances.

Earlier quoted context omitted.

How often are you driving 1800 miles in a day.

Truly autonomous cars could drive you cross country while you work, eat, sleep and consume entertainment all within the car. With those kinds of efficiencies it's pretty attractive regardless, but very short charging breaks would be even more attractive.

Truly autonomous cars will go on strike and tell you meatbags to take a hike!

In what temperature, gradient, tires, road type, traffic or speed? kWh is better.

>Not everyone lives in the US or Australia or Canada

Hence, segment the market.

>there‘s convenient public transport for long distances.

Public transportation has good use cases, but also terrible use cases. It is good if you don't have stuff and are going to an urban center,which covers a lot of needs. If you want to clean out your mom's house, or go camping with friends,it sucks

How is 250 enough. On roadtrips I can easily go 500 miles in a day. With 900 miles you could go on trip and return home before you need to charge your battery again. With this sort of range it might actually make EV pickups useful. You can now probably tow an RV 400-500 miles in cold weather with this. If this is legit, it’s going to revolutionize everything.

Or could you add extra capacity like drop tanks for fighters in WWII. Use built in 259 mile range normally. Rent a 900 mile range extender pack for your cross country trips.
