The invention provides a direct-current charging pile parallel-operation charging system. The direct-current charging pile parallel-operation charging system comprises a charging circuit, a charging gun assembly, a BMS communicator and a main control board, wherein the charging circuit is electrically connected with the charging gun assembly and the main control board; the charging gun assembly comprises two charging guns, each charging gun is provided with a BMS communication receiver, and the BMS communication receivers are in communication connection with the BMS controller; and the main control board is in communication connection with the BMS communicator. The invention further provides a direct-current charging pile parallel-operation charging method. The method comprises steps of detecting a connection state of the charging gun and the charging interface of the vehicle, and starting the parallel-operation charging module of the charging pile to start charging after detecting that the charging interface of the charging gun is connected with the charging interface of the target vehicle; receiving BMS communication data returned by the target vehicle, and confirming a charging interface receiving the BMS communication data; and outputting current to the target vehicle by taking the charging gun as a host. By controlling the parallel operation charging mode, the application scene of the charging pile is enriched, and the effects of single-machine charging and parallel operation double-gun simultaneous charging are achieved.

    本发明提供一种直流充电桩并机充电系统,包括充电电路、充电枪组件、BMS通讯器及主控板;充电电路分别与充电枪组件及主控板电连接;充电枪组件包括两个充电枪,且充电枪分别置有BMS通信接收器,BMS通信接收器与BMS控制器通信连接;主控板与BMS通信器通信连接。本发明还提供一种直流充电桩并机充电方法,通过检测充电枪与车辆的充电接口连接状态,并在检测到充电枪的充电接口与目标车辆的充电接口连接后,启用充电桩的并机充电模块开始充电;接收目标车辆返回的BMS通信数据,确认接收BMS通信数据的充电接口;以充电枪为主机向所述目标车辆输出电流。本发明通过控制并机充电模式,丰富了充电桩应用场景,实现了单机充电以及并机双枪同时充电的效果。
