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. Of course, high-voltage and high-power charging facilities must first ensure a safe environment.
In terms of the optional installation of Tesla charging piles, many owners are entangled in 380V or 220V. The 220V voltage charging speed is 50-60km\/h, and the 380V voltage charging speed is 70-80km\/h. If 220V is charged from zero, it may not be full in one night, usually takes about 10 hours, and 380V charging pile can be filled in about 8 hours. From the above data comparison, it can be seen that 380V is better than 220V, and the most obvious advantage is fast charging.
Some consumers will wonder if the 380V will bring a greater risk of fire, and this problem should be paid attention to. However, the 380V charging pile or 220V charging pile produced by regular manufacturers are all qualified tests. There will be no high voltage high risk, low voltage will be a low risk result.
