The invention relates to the field of electric vehicle charging, and discloses a charging device for maximizing the charging efficiency of a direct current charger, which comprises charging terminals, charging modules and a direct current contactor, and is characterized in that the charging modules are divided into a plurality of charging modules according to the number of the charging terminals; a charging gun of the charging terminal is connected with a group of charging modules through a direct current contactor, modules in each charging module are arranged in parallel, and adjacent charging modules are connected through a direct current contactor. The method has the effects that the optimal output power interval of the module is set according to the output characteristic curve of the module, and the calling scheme of the module is updated according to the use condition of the charging terminal and the real-time requirement of the vehicle end in the charging process, so that the actual output of the module is always in the optimal output power interval range.

    本发明涉及电动汽车充电领域,公开了一种直流充电机最大化充电效率的充电装置,包括充电终端、充电模块和直流接触器,所述充电模块根据所述充电终端的数量分为多个充电模组,所述充电终端的充电枪与一组充电模组通过直流接触器连接,每个充电模组内的模块并联设置,相邻充电模组间通过直流接触器连接。具有根据模块的输出特性曲线,设定模块最佳输出功率区间,在充电过程中,根据充电终端的使用情况以及车端的实时需求,更新模块调用方案,使模块实际输出始终在其最佳输出功率区间范围内的效果。
