The application discloses a direct current charging pile comprising an alternating current power supply port used for connecting an alternating current power supply outside the direct current charging pile, and the alternating current power supply is used for providing multi-phase alternating current for the direct current charging pile; the charging module is connected with the alternating current power supply port through a multi-phase alternating current bus, and the charging module is used for converting the multi-phase alternating current into direct current so as to charge an electric vehicle; and the plurality of direct current contactors are arranged on the multi-phase alternating current bus between the charging module and the alternating current power supply port, the plurality of direct current contactors are in one-to-one correspondence with the multi-phase alternating current bus, and the plurality of direct current contactors are used for controlling the on-off of the multi-phase alternating current bus. According to the application, the on-off of the multi-phase alternating current bus is controlled through the plurality of direct current contactors, so that the layout space in the direct current charging pile is saved, and the complexity of a control circuit in the direct current charging pile and the production cost of the direct current charging pile are reduced.

    本申请披露了一种直流充电桩,包括:交流电源端口,用于连接所述直流充电桩外部的交流电源,所述交流电源用于为所述直流充电桩提供多相交流电;充电模块,所述充电模块通过多相交流电母线与所述交流电源端口连接,所述充电模块用于将所述多相交流电转换为直流电,以对电动汽车进行充电;多个直流接触器,设置在所述充电模块与所述交流电源端口之间的所述多相交流电母线上,多个所述直流接触器与所述多相交流电母线一一对应,多个所述直流接触器用于控制所述多相交流电母线的通断。本申请通过多个直流接触器控制多相交流电母线的通断,从而有助于节省直流充电桩内部的布局空间,降低直流充电桩中控制电路的复杂度以及直流充电桩的生产成本。
