Why does a car that supports 7kW single-phase (1 phase) only get 3.6kW from an 11kW charger?
Published · Updated
A4: Because the 11kW charger is a 3-phase system, but the car supports only 1 phase, so it can draw only 1/3 of the total power.

Examples • A 7kW / 1-phase car on an 11kW charger → gets only 3.6kW • A 7kW / 1-phase car on a 7kW charger → gets the full 7.3kW Summary: If your car supports only 1 phase → a 7kW charger will be faster and better value
Which charger can your home take?
The right charger depends on your meter size, your existing electrical panel and the distance from the panel to your parking spot — not just your car model.
