Joe Average shouldn't be playing around with these power levels without some serious safety protocols that he can't shortcut.

But you would need need much more than 72kw to refill a 300kw battery in 10 mins like you can refill a gas tank with that kind of range in 10 mins. Obviously you would need 300kw in just 10 mins which would be 6 times 300 or 1800kw or a 30kv feed at 60 amps. That's just to do one car but if 10 wanted to refill at the same time, as is common at the petrol station you would need 10 times the volts or 10 times the amps either way too much.
Bigger batteries for more range just means long charging times and in a home setting that could mean days not hours and certainly never minutes.
