The embodiment of the invention provides a charging connection device and a charging system. The charging connection device comprises a plurality of direct current interfaces and a switch module. Wherein the first direct current interface and the second direct current interface in the plurality of direct current interfaces are respectively connected with a direct current bus of one charging device, and the direct current bus of each charging device is used for collecting direct current output by the plurality of power conversion devices of each charging device. Wherein the first direct-current interface and the second direct-current interface are connected through the switch module, so that power transmission is carried out between a bus of one charging device connected with the first direct-current interface and a direct-current bus of another charging device connected with the second direct-current interface; therefore, the maximum output power of the whole machine of each charging device connected with the charging connection device can be flexibly adjusted so as to meet different requirements of different charging scenes on the maximum output power of the whole machine of the charging device.
本申请实施例提供了一种充电连接装置和充电系统。充电连接装置包括多个直流接口和开关模组。其中,多个直流接口中的第一直流接口和第二直流接口各连接一个充电设备的直流母线,每个充电设备的直流母线用于汇集每个充电设备的多个功率转换装置输出的直流电。其中,第一直流接口和第二直流接口通过开关模组连接,以使第一直流接口连接的一个充电设备的母线与第二直流接口连接的另一个充电设备的直流母线之间进行功率传输,从而灵活调整与充电连接装置连接的每个充电设备的整机最大输出功率,以满足不同充电场景对充电设备的整机最大输出功率的不同需求。
