The invention provides charging equipment and a charging system. The charging equipment comprises eight power units, eight switch units, four first switch devices and at least one second switch device, every four power units and every four switch units form a power unit group, in each power unit group, the output ends of the four power units are sequentially connected to form a loop, and in the loop, the output ends of every two adjacent power units are connected or disconnected through one switch unit; the four power units in different power unit groups are in one-to-one correspondence, and the output ends of the two corresponding power units are connected through a first switching device; and the second switching device is connected between the output ends of the two non-corresponding power units, or the second switching device is connected between the output ends of the two non-adjacent power units. By arranging a plurality of power units and a plurality of switching devices, the power distribution flexibility is improved.
本发明提供一种充电设备和充电系统,包括八个功率单元、八个开关单元、四个第一开关装置和至少一个第二开关装置;每四个功率单元和每四个开关单元为一组功率单元组,在各功率单元组中,四个功率单元的输出端依次连接形成环路,在环路中,每相邻两个功率单元的输出端之间通过一个开关单元实现连通或断开;不同功率单元组中的四个功率单元分别一一对应,且两个对应的功率单元的输出端通过一个第一开关装置连接;第二开关装置连接在两个互不对应的功率单元的输出端之间,或者,第二开关装置连接在两个互不相邻的功率单元的输出端之间。通过设置多个功率单元和多个开关器件,提高功率分配灵活性。
