Re: Toyota’s advanced battery technology roadmap

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.

How often are you driving 1800 miles in a day.

Supposedly, V4 chargers are still currently capped at 250kW output (same as current L3 chargers), but are capable of upwards of 615 amps once more cars are capable of charging at 800 volts.

I don't know what building 100,000 of them will take, but it'll be a lot of metal for sure.

932 miles is suspiciously specific.

It is 1500 km translated for US readers.

1500km is suspiciously specific. What next, I'll go to the shops and buy EXACTLY two litres of milk? 12 eggs??

Never, but I’m trying to understand what the experience would be like. If you charge at home then you are looking at like 2 days to fully charge at 240v. What I’m wondering is if these ranges are necessary or realistic for electric cars even if the storage tech is there. Maybe 4-500 miles is the max anyone would want regardless of how long charging could theoretically take if you were connected directly to a nuclear generator or something.

But why would you need to fully charge? What matters is charging enough in a day to cover your daily needs.
