That’s 210,000 watts for 10 minutes with 100% charging efficiency - which is very unlikely... Or 875 Amps at 240 Volts... That’ll take another larger battery pack as a charger. Nobodies home or normal business is going to be able to supply that kind of short term demand directly. Typical modern homes have a 200 Amp panel.
I would assume that stations would exist for this, and the options of longer charges would be optional.
The assumption.
