Back of the envelope calculation to charge 100KWh battery in 10 minutes is about 750A [1] assuming 100% efficiency at 800V (back of the envelope optimism). Tesla Superchargers are already capable of 800A and Porsche is already using 800V. So it doesn't seem that much crazier than what we're already doing.
[1] 100KWh * 1000(W/Kw) / 800V * 6 (10min/hr) = 750A
