Our house has a bunch of exterior 110v outlets, but they are all on the same 20A circuit. Our level 1 charger takes many hours to charge our small EV battery, and draws 16A. There's no way for it to politely ask the circuit breaker how much amperage is left on the circuit.

If I was wiring a parking garage, I'd likely run level 2 charges, since you get twice the charge rate for the same amount of copper.
