I can get 11kW of 3-phase power to charge my car from the garage of my Grandma's house, that was built in the late 50's. I could do up to 22kW, but pretty much no EV supports 22kW AC charging (weird patent stuff IIRC). I can also charge at 2.7kW from a regular Schuko outlet. The single-phase thing is why electric kettles aren't a thing in the US, you just can't provide enough power for them to be usable. IIRC the maximum for US outlets is around 1.5kW, (most?) European plugs can provide around 2.3-2.7kW.
