The invention provides a low-power-consumption control system of a direct-current charging pile. An I/O interface of a controller of the direct-current charging pile is connected with an alternating-current contactor through an intermediate relay, the output end of the alternating-current contactor is connected with a low-power-consumption AC/DC high-frequency power module, the AC/DC high-frequency power module is connected with a charging plug through the direct-current contactor, and the charging plug is connected with a battery through a vehicle charging socket. The controller of the direct-current charging pile is provided with an analog quantity detection port, the analog quantity detection port is connected with a charging gun communication line interface through a communication line, a direct-current charging gun communication line is connected with a vehicle BMS, and the vehicle BMS is connected with the battery. According to the charging pile, whether a charging task exists or not is detected through the analog quantity detection port of the controller, when the charging pile does not have the charging task, the controller directly controls the alternating current contactor to be powered off through the Y point of the I/O port or controls the alternating current contactor to be powered off through the intermediate relay, under the standby condition, the AC/DC module of the direct current charging pile is in the powered-off state, and the low-energy-consumption controller is in a dormant state, so that the whole direct-current charging pile is in a low-energy-consumption state.

    一种直流充电桩低功耗控制系统,直流充电桩的控制器的I/O接口通过中间继电器连接交流接触器,交流接触器输出端连接低功耗AC/DC高频电源模块,AC/DC高频电源模块通过直流接触器连接充电插头,充电插头通过车辆充电插座连接至电池。直流充电桩的控制器设有模拟量检测口,模拟量检测口通过通讯线连接充电枪通讯线接口,直流充电枪通讯线连接车辆BMS,车辆BMS连接电池。本发明充电桩通过控制器的模拟量检测口检测是否有充电任务,充电桩没有充电任务时,控制器通过I/O口的Y点直接控制或者通过中间继电器控制交流接触器断电,实现了在待机的情况下,直流充电桩的AC/DC模块处于断电状态,低能耗的控制器处于休眠状态,从而达到了整个直流充电桩处于低能耗状态。
