Toyota CEO talks about why he isn’t all-in on EVs

I'd like to see what kind of electrical infra you need to (even partially) charge 20k cars in 5 minutes.

That's about one Tsar Bomba of energy.

This is too high by 4 orders of magnitude. 100 kWh is a larger than average battery capacity for a contemporary BEV [1]. That's 2000 MWh for 20,000 vehicles charging from empty (modulo charging inefficiencies). 1 megaton is 4.18 * 10^15 joules or 1,162,000 MWh [2] while the Tsar Bomba had a yield of at least 50 megatons as tested [3]. So charging 20k electric cars from empty requires about 0.003% as much energy as the Tsar Bomba released.

You're right, I jumped from kWh -> TWh, where it should've been kWh -> GWh.

Still, if you look at power, that much energy moving in 5 minutes is about 24GW. That's massive. Unless I'm wrong with numbers again :P.
