In the US you can use the Mobile Charge Connect or the standard Mobile Charge with a single phase 240V AC 50 A socket to charge at 9.6 kw. The availible plug styles are NEMA 14-50 or NEMA 6-50. 14-50 is common for electric clothes dryers and uses 4 wires: 2 hot, one neutral and one ground. 6-50 is common for shop equipment like welders, and uses 3 wires, 2 hot and one neutral. On either of these chargers the draw is 40 A, because 80% of circuit breaker capacity is the recommended maximum. I have seen YouTube videos showing how to configure the Mobile Charge Connect for 240V circuits with less than 50 A capacity.
I know nothing about 3-phase systems.
My wife’s Audi A3 E-tron has a charger that looks much like the standard Mobile Charge, but while it came with a 6-50 plug, it only draws 16A, and thus is for a circuit with a 20 A breaker.
