When a Wall Connector or Mobile Connector plugs into the charge port it provides alternating current, also known as AC power, to your vehicle. Batteries store energy as direct current, also known as DC energy.
The onboard charger, which is built in your vehicle, handles this by converting the AC power into DC energy so that it can be stored in the battery.
Different Tesla vehicles have different onboard charger capabilities. Maximum current and power draw, based on the connected power supply below:
|Max Charge Power Based On Vehicle Capabilities And Wall Connector Current Settings
|230 V Single-Phase
|230 V Three-Phase Delta
|400 V Three-Phase Wye
|7.4 kW (32 A)
|11 kW (28 A)
|11 kW (16 A)
We recommend installing a Wall Connector at home and leaving the Mobile Connector in the trunk of the vehicle as a backup option while on the road.
