With a charging cable like a tree trunk, that doubles as a space heater?

IIRC there are water cooled cables that can do 350kW, the charging is generally done at pretty high voltages so you "only" need like 50 amps or something totally reasonable. Obviously the power delivery to a station simultaneously charging 10 of these would be challenging, but it's not outside of the realm of possibility.

But this battery takes in around 384kw assuming 100% efficiency.

400km*16kwh/100km/10minutes

No 350kW charging only needs 50 amps. That would mean charging at 7000V, which no car supports.

The existing 250kW charging from Tesla maxes out at 400V, which is 625 amps. The EA 350kW chargers run at 800V, so they use ~437 amps. The cables are thick, but not that thick honestly.

Oh you're absolutely right, I had meant 500 amps. Thanks for the correction.
