Onboard Charger

When a Wall Connector or Mobile Connector plugs into the charge port it provides alternating current, also known as AC power, to your car. Batteries store energy as direct current, also known as DC energy.

The onboard charger, which is built in your car, handles this by converting the AC power into DC energy so that it can be stored in the battery.

Each Tesla has different charging capabilities depending on its onboard charger. Open the charging menu from the charge icon on your touchscreen to view your maximum charge rate.

Your Tesla Onboard Charger Rate (kW)* Typical Added Range
Model 3 11 75 kW/h
Model S / Model X 16.5 90-80 km/h
Model S before May 2016 11 or 22
Check vehicle configuration
60 km/h
110 km/h

We recommend installing a Wall Connector at home and leaving the Mobile Connector in the boot of the car as a backup option while on the road.
