In the direct current charging pile, the unit with the largest standby power consumption is arranged in an AC/DC high-frequency power supply module. The charging pile controller is provided with 1I/O port and 1 analog quantity detection port CC +/CC-in a reserved mode and used for controlling an alternating current power supply at a main input end, under the general condition, the main alternating current input power supply is used by matching a main molded case circuit breaker with an alternating current contactor, the rear end of the main molded case circuit breaker is connected with the alternating current contactor, and the rear end of the alternating current contactor is connected with a low-power-consumption AC/DC high-frequency power supply module. And a controller of the direct current pile is connected to the front end of the alternating current contactor, so that the controller is in a long power supply state. The direct current controller has a timing dormancy function, and when the standby time exceeds the set time, the controller enters a low-power-consumption dormancy state.
