Onboard Charger

When a Wall 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.

Different Tesla cars have different onboard charger capabilities. Open the charging menu from the charge icon on your touchscreen to view your maximum charge rate.

Onboard Charger Recommended circuit breaker for max charge rate with Wall Connector
