The invention discloses a single or multiple charging unit distribution system for a high-power DC charger, each charging unit comprises a charging gun module, a series switch module and a charging module, a plurality of charging modules are connected in series, a series switch module is arranged on a line between two adjacent charging modules, and the series switch module is connected with the charging gun module. Each charging module is connected with one charging gun module; the controller is used for detecting the charging demand power of one or more charging gun modules in the charging unit and automatically connecting or disconnecting one or more charging modules according to the detection result. In the invention, when the charging power demand at a certain charging gun module is relatively high, the power access of other charging modules can be automatically completed, and the accessed charging module is cut off after the charging power is reduced, so that the use of all the charging modules is coordinated, the charging effect when the charging power is changed is ensured, and the charging efficiency is improved. And the idle charging module can enter a standby state so as to save electric power resources.
本发明公开了一种大功率直流充电机用单个或多个充电单元分配系统,所述充电单元包括充电枪模块、串联开关模块和充电模块,多个充电模块串联连接,相邻的两个充电模块之间的线路上设置有一个串联开关模块,每个充电模块分别连接一个充电枪模块;控制器用于检测充电单元中的一个或多个充电枪模块的充电需求功率并根据检测结果自动接入或切除一个或多个充电模块。本发明中,当某个充电枪模块处的充电功率需求较高时,可以自动完成其他充电模块的功率接入,并在充电功率降低后切除上述接入的充电模块,由此协调所有的充电模块的使用,既保证了充电功率变化时的充电效果,还使空闲的充电模块能够进入待机状态以节省电力资源。
