The dynamic switching system is annular, a plurality of power modules are uniformly distributed on the outermost layer, a charging pile is arranged on the inner layer, and the power modules are connected with the charging pile through a power switch, a change-over switch and a load switch; the switching strategy algorithm module monitors the power demand quantity of the external terminal and the time when a user expects to use the charging pile to charge the external terminal in real time, so that a charging priority list of the external terminal is calculated, grouping of power modules is completed, in addition, the charging priority can be manually adjusted through a charging administrator, and the charging efficiency is improved. And finally, the control module controls the power modules in the same group to be connected to the same charging pile, and simultaneously controls the corresponding power switch, the change-over switch and the load switch in the same group to be switched on so as to charge an external terminal. Therefore, the number of used switches is greatly reduced, the system cost is reduced, and the switching process is simplified.
本发明公开了一种直流充电桩功率模块的动态切换系统呈现环状,最外层均匀分布着若干个功率模块,内层为充电桩,功率模块与充电桩之间通过功率开关、切换开关和负载开关连接;切换策略算法模块实时监测外部终端的功率需求量,以及用户期望使用充电桩对外部终端进行充电的时间,从而计算出外部终端的充电优先级列表并完成功率模块的分组,此外可通过充电管理员人为对充电优先级进行调整,最后控制模块控制同一组别内的功率模块连接到同一充电桩,同时控制同一组别内对应的功率开关、切换开关以及负载开关导通从而为外部终端充电;这样大大减少了开关使用数量,降低系统成本,同时也简化了切换过程。
