The average Tesla home charge is 7kw and 20kw. Corresponding to 220V and 380V voltage respectively. Generally, the greater the power and voltage, the faster the charging speed. Of course, high-voltage and high-power charging facilities must first ensure a safe environment. If the Tesla AC pile is slowly filled, 220V single-phase power supply can be used. If it is a fast filling pile, you need 380V three-phase power input.
Tesla's household charging pile 220V power supply is about 7000 watts. The voltage power of 380V is about 20 kW
