[0002] New energy vehicles refer to vehicles powered by on-vehicle power sources and driven by motors. Since they have relatively less impact on the environment compared to traditional vehicles, their prospects are widely optimistic. New energy vehicles usually use charging piles for charging. The input end of the charging pile is directly connected to the power grid, and the output end is equipped with a charging gun for charging new energy vehicles.

[0003] Currently, with the popularization of new energy electric vehicles, the development of fast charging technology is becoming increasingly important. In order to improve the charging speed, make the charging time shorter, and provide a better user experience, the charging current and power of the charging gun for the load are bound to become larger and larger.
