The invention discloses a cluster type alternating-current ordered charger and a charging method, and belongs to the technical field of electric vehicle charging piles. The cluster type alternating current ordered charger comprises a host and a plurality of terminal interfaces, wherein the host comprises a main control unit and a plurality of output units, and each output unit is connected with each terminal interface; the output units comprise alternating current contactors, electric meters and control guide circuits; each alternating current contactor is connected with the corresponding electric meter; each electric meter and the control guide circuit are connected with the corresponding terminal interface. The alternating current contactors, the ammeters and the control guide circuits are respectively in communication connection with the main control unit, and the on-off of the alternating current contactors is controlled through the main control unit, and therefore, a plurality ofterminal interfaces can be uniformly controlled, the output current of each terminal interface can be reasonably distributed, the requirement of each charging interface can be met under the conditionof external power supply shortage, and meanwhile, the average cost of each interface is greatly reduced due to the sharing of the same main control unit.

    本发明公开了一种集群式交流有序充电机及充电方法,属于电动汽车充电桩的技术领域,包括主机和多个终端接口,所述主机包括主控单元和多个输出单元,各所述输出单元分别与各所述终端接口连接;所述输出单元包括交流接触器、电表和控制导引电路,所述交流接触器与电表连接,电表和控制导引电路均与对应的终端接口连接,交流接触器、电表和控制导引电路分别与主控单元通信连接并通过主控单元控制所述交流接触器的通断,以达到多个终端接口的统一控制,可合理分配各个终端接口的输出电流,可在外部供电紧张的情况下,使每个充电接口的需求都能得到满足,同时,由于共用同一主控单元,大大降低了各接口的平均成本。
