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, converts power from AC to DC so that it can be stored in the battery.
Different Tesla cars have different onboard charger capabilities. Maximum current and power draw, based on the connected power supply below:
|Vehicle||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|
|Model S, Model 3, Model X, Model Y||7.4 kW (32 A)||11 kW (28 A)||11 kW (16 A)|
