The invention provides a charging power distribution system and method for a charging pile and the charging pile. The system comprises at least three power output ports, a plurality of charging modules, a plurality of electric control switches and a control unit, each power output port and each charging module are respectively connected to the annular bus, and the annular bus forms a plurality of main edges by taking the power output ports as boundaries; an electric control switch is arranged on the annular bus between the adjacent charging modules in each main side, and an electric control switch is arranged on the annular bus between the adjacent power output ports and the charging modules in each main side; wherein the annular bus corresponding to the position of each electric control switch is a sub-side; a bridge circuit is arranged between every two adjacent main edges; an electric control switch is arranged on the bridge circuit; and the control unit is electrically connected with each electric control switch. By using the system provided by the embodiment of the invention, the bus length and the use number of the electric control switches can be reduced.

    本公开提供一种用于充电桩的充电功率分配系统、方法以及充电桩。其中,系统包括:至少三个功率输出端口、多个充电模块、多个电控开关以及控制单元;每个功率输出端口和每个充电模块分别连接在环形母线上,其中,环形母线以功率输出端口为分界形成多个主边;在每条主边中,相邻的充电模块之间的环形母线上设置一个电控开关,在每条主边中,相邻的功率输出端口与充电模块之间的环形母线上设置一个电控开关;其中,每个电控开关的位置对应的环形母线为一个子边;在相邻的两条主边之间设置有一个桥路;在桥路上设置一个电控开关;控制单元与每个电控开关电连接。利用本公开实施例提供的系统,可以减少母线长度以及电控开关使用数量。
