The invention provides a local flexible power distribution system of a direct current charging pile. The local flexible power distribution system comprises a charging interface, a half-and-half charging module and a flexible charging module, the pair of half charging modules is connected with the charging interfaces in a one-to-one correspondence manner, the flexible charging module is connected with each charging interface, and each pair of half charging modules is connected; the flexible charging module comprises a flexible control module connected with each charging interface and a plurality of first charging modules connected with the flexible control module, and each pair of half charging modules comprises a plurality of second charging modules; when the plurality of charging interfaces work, the plurality of second charging modules of each half-and-half charging module respectively supply power to the corresponding charging interfaces, or the plurality of half-and-half charging modules supply power to one charging interface in a centralized manner, and the flexible charging module distributes the plurality of first charging modules to supply power to the charging interfaces according to the required power of each charging interface. Therefore, the problem of low idle utilization rate of the charging module is solved, and the cost is reduced.

    本申请提供了一种直流充电桩的局部柔性功率分配系统,包括:充电接口、对半充电模组和柔性充电模组;一对半充电模组分别与一充电接口一一对应相连,柔性充电模组分别与每一充电接口相连,且每一对半充电模组之间相连;柔性充电模组包括与每一充电接口相连的柔性控制模块和多个与柔性控制模块相连的第一充电模块,每一对半充电模块均包括多个第二充电模块;当多个充电接口工作时,每一对半充电模组的多个第二充电模块分别为对应的充电接口供电,或多个对半充电模组集中对一充电接口供电,柔性充电模组根据每一充电接口的需求功率大小分配若干第一充电模块为充电接口供电。从而改善了充电模块空闲利用率低的问题和降低了成本问题。
