If it is 380V voltage, it is best to reserve 10 square wires.
The 220v power supply of Tesla's household charging pile is about 7kw, and the 380v power supply is about 20kw. Tesla has a household charging pile as standard for its models, which uses 220V voltage and can travel about 40km per hour on a charge. From the third quarter of 2015, Tesla has provided users with the option of high-power home charging piles, which use 380V voltage and can reach about 100km per hour of charging.
Tesla generally uses 5 cores of 10 square mm, and cables over 120 meters are 5 cores of 16 square mm cables. The power of Tesla household charging pile is generally divided into 7kW and 20kW, corresponding to 220V and 380V voltage respectively. Consumers can understand that the greater the power and voltage, the faster the charging speed.
