The invention discloses a charging system and a charging method, the charging system comprises a plurality of charging modules, and the plurality of charging modules are arranged in parallel; each charging module comprises a plurality of DC output loops; wherein the plurality of charging modules at least comprise a first charging module and a second charging module, the first charging module comprises M first DC output loops, and the second charging module comprises N second DC output loops; the charging system further comprises a parallel switch module, the parallel switch module comprises Pparallel switches, and P is larger than or equal to 1 and smaller than or equal to MIN [M, N]. At least one first direct-current output loop is connected with one second direct-current output loop through one parallel switch. The DC output loops among different charging modules are connected through the parallel switch, so that the relatively flexible power output of different DC output loops is realized, the charging power coordination among different charging modules is realized, and the charging efficiency of the charging system is improved.
本发明公开了一种充电系统和充电方法,充电系统包括多个充电模块,多个充电模块并联设置;每个充电模块包括多个直流输出回路;多个充电模块至少包括第一充电模块和第二充电模块,第一充电模块包括M个第一直流输出回路,第二充电模块包括N个第二直流输出回路;充电系统还包括并联开关模块,并联开关模块包括P个并联开关,其中,1≤P≤MIN[M,N];至少存在一条第一直流输出回路通过一个并联开关与一条第二直流输出回路连接。通过设置不同充电模块之间的直流输出回路通过并联开关连接,实现不同直流输出回路相对灵活的功率输出,同时实现不同充电模块之间的充电功率协调,提升充电系统的充电效率。
