Hmmm. To charge an electric car in a few minutes, how many hundreds of amps will be required to do that?
The Leaf has a 24 kwh battery.
So, if I remember my numbers correctly, it would take 104 amps to charge it in an hour using 230 volts. 208 amps in 30 minutes. 416 amps in 15, which is about the longest you can call “a few minutes.”
Getting some pretty high level juice going there.
Actually, these theoretical numbers wouldn’t work at all due to efficiency losses in charging. Also likely to be a LOT of heat generated in any charging process that rapid. Which is, of course, where the waste energy is going.
From the way it sounds....exactly what the charger puts out. The battery is sponge-like. But your point is valid. If there isn't some limiting circuitry in these new batteries. If not, they'll suck whatever a charger will throw them and the charger will fry.
