Charging pile group power control method

The invention provides a charging pile group power control method, which comprises a main controller, the main controller is used as a system brain to carry out group management and group control on managed alternating current charging piles, on power, three-phase mains supply is protected by a 3P main circuit breaker and then enters an alternating current charging pile protection micro circuit breaker (1PN micro circuit breaker with electric leakage protection) in six paths, and the three-phase mains supply enters an alternating current charging pile protection micro circuit breaker (1PN micro circuit breaker with electric leakage protection). Then the AC charging pile is connected; the main controller is connected with all the alternating current charging piles through a CAN bus for communication interaction, and the main controller is further in communication interaction with a cloud platform through 4G/5G; in the aspect of power supply, low-voltage power supply parts of all the alternating-current chargin
