The real question is how do you pump that many kwhrs that fast without creating massive heat and electrical spikes?

Probably with 10 or 20 thousand volts. With 20kV you would need 60 amps to deliver 1200kW for the five minute charge. Those are very dangerous voltages and currents however.

Yes! That would be quite a load under the circumstance. Maybe they'll add a load of gold to the design to lower the resistance.
