Charging calculator
How long, and how much?
Pick a car and a charger. We apply the car's own charging limit, so a fast charger never looks faster than the car can take.

How this is worked out
Energy needed = battery × (target minus start) ÷ efficiency. Power is the lower of the charger and the car's own limit.
AC charging is close to constant power, so these times are fairly reliable. A wall socket gives around 2.3 kW; a dedicated home charger 7 kW or more.
