The invention discloses a power distribution support module used in a direct-current charging pile. The power distribution support module can distribute any charging module in an idle state in the direct-current charging pile to any charging gun on the charging pile according to charging requirements. Each charging module is independently connected with a plurality of charging guns through a switching matrix circuit which comprises a plurality of groups of switch branch circuits and corresponds to the charging module. Each group of switch branch circuit consists of a positive path and a negative path, the input end and the output end of the positive path are respectively connected with the positive output end of the charging module and the positive input end of the corresponding charging gun, the input end and the output end of the negative path are connected with the negative output end of the corresponding charging gun and the negative input end of the charging module respectively, and connection or disconnection of each group of switch branch circuit is controlled by an upper computer of the charging pile. The equipment cost of the charging pile is reduced, the driving speed ishigh, the utilization rate of each charging module can be fully improved, the internal space of the direct-current charging pile is reduced, and the charging speed under power support application is increased.
一种可将直流充电桩内处于空闲状态的任一充电模组依据充电需求分配给该充电桩上任一充电枪的用于直流充电桩内的功率分配支援模块。其中,每个充电模组都通过与其对应的一个包含多组开关分电路的切换矩阵电路分别与多个充电枪单独相接,每组开关分电路由正、负极通路组成,正极通路的输入端和输出端分别与该充电模组的正输出端和对应的充电枪的正输入端相接,负极通路的输入端和输出端分别与对应的充电枪的负输出端和该充电模组的负输入端相接,每组开关分电路的导通或断开由该充电桩的上位机控制。其不仅使充电桩的设备成本降低、驱动速度快,而且还可充分提高各充电模组的利用率,减少直流充电桩的内部空间,加快功率支援应用下的充电速度。
