According to a multi-gun charging pile and a charging pile circuit, only one AC/DC unit is adopted for rectification, the AC/DC unit is connected with the multiple DC/DC units in a hanging mode at thesame time, and therefore, the number of rectification unit controllers and control circuits is small, that is, the number of passive devices is small, the rectification cost is low, the standby powerconsumption is small, and the reactive power loss is low; moreover, the output end of each DC/DC unit is connected to the corresponding charging gun port through the power distribution unit, and thecontrol unit controls the power distribution unit to act according to the output voltage of each DC/DC unit and the power demand of the corresponding charging gun port, so that at least one DC/DC unitis connected to the corresponding charging gun port, and power distribution of the corresponding charging gun port is realized, that is to say, the multi-gun charging pile circuit is provided with the multiple charging gun ports, power distribution is conducted on the charging gun ports through the control unit and the power distribution unit, and therefore, the charging pile can be used by multiple users at the same time, and the utilization rate of the charging pile is increased.
本发明提供一种多枪的充电桩及充电桩电路,仅采用一个AC/DC单元进行整流,以该AC/DC单元同时挂接多个DC/DC单元,因此,整流单元控制器及控制电路少,即无源器件少,进而整流成本低、待机功耗小且无功损耗低;并且,各DC/DC单元输出端均通过功率分配单元连接至对应的充电枪口,由控制单元根据各DC/DC单元的输出电压以及相应充电枪口的功率需求,控制功率分配单元进行动作,使至少一个DC/DC单元连接至对应充电枪口,实现对相应充电枪口的功率分配;也即该多枪的充电桩电路设置有多个充电枪口,通过控制单元及功率分配单元对各个充电枪口进行功率分配,因而能够同时满足多个用户使用,提高了充电桩的利用率。
