The invention relates to a direct-current charging pile and a direct-current charging system thereof. The direct-current charging pile comprises a controller, a plurality of direct-current output loops used for being connected with charging guns and a bus contactor wiring board. Bus contactor contacts and corresponding bus contactor control coils are connected in series between corresponding terminals of the bus contactor wiring board; each DC output loop is connected to a bus contactor contact through a corresponding terminal of a bus contactor wiring board, and the corresponding bus contactor is used for controlling the on-off of the corresponding charging loop; the controller is in control connection with a bus contactor control coil through a corresponding terminal of a bus contactor wiring board; and the controller sends a control instruction to a bus contactor coil through the bus contactor wiring board so as to control the closing of a contact of the bus contactor, so that the direct-current output loop is switched on through the bus contactor wiring board, and charging current is output.

    本发明涉及一种直流充电桩及其直流充电系统,包括控制器、若干个用于连接充电枪的直流输出回路和母线接触器接线板;所述母线接触器接线板对应端子之间串接有母线接触器触点和对应的母线接触器控制线圈;各个直流输出回路中通过母线接触器接线板对应端子接入母线接触器触点,对应的母线接触器用于控制对应充电回路的通断;所述控制器通过母线接触器接线板对应端子控制连接母线接触器控制线圈;所述控制器通过母线接触器接线板将控制指令发送给母线接触器线圈,以控制母线接触器触点闭合,实现直流输出回路通过母线接触器接线板接通,输出充电电流。
