The invention belongs to the technical field of charging systems, and particularly relates to a group control charging system and a charging method. The group control charging system comprises a direct-current power bus and a plurality of chargers which are in communication connection with one another, the charger comprises a charging module used for charging the electric vehicle, a charging connector connected with the output end of the charging module and a control unit used for detecting or controlling the use state of the charging module and obtaining the charging requirement of the electric vehicle, and the direct-current power bus is connected with the charging module and used for obtaining electric energy output by the charging module. The direct-current power bus is further connected with the charging connector and used for transmitting electric energy collected by the direct-current power bus to the electric vehicle. According to the group control charging system, other charging modules in an idle state can be called through the direct-current power bus, so that the charging efficiency of the electric vehicle is greatly improved, a flexible charging pile does not need to be independently constructed, and in addition, the group control charging system can be rapidly and conveniently expanded.

    本发明属于充电系统技术领域,具体涉及一种群控充电系统及充电方法。其中的群控充电系统包括直流动力母线以及互相通信连接的多台充电机,充电机包括用于向电动汽车充电的充电模块和与充电模块输出端连接的充电连接器以及用于检测或控制充电模块的使用状态并用于获取电动汽车的充电需求的控制单元,直流动力母线与充电模块连接,用于获取充电模块输出的电能,直流动力母线还与充电连接器连接,用于将直流动力母线收集的电能传输给电动汽车。本发明的群控充电系统可通过直流动力母线借调处于空闲状态的其它充电模块,从而大大提高对电动汽车的充电效率,不需要独立建设柔性充电堆,此外本发明的群控充电系统可快速便捷地扩展。
