The invention discloses a high-power over-charging and fast-charging dual-purpose direct-current charging system which comprises a plurality of charging terminals, a plurality of power supply modules, a plurality of first switching assemblies, a second switching assembly and a charging control module. Wherein the second switching assembly comprises parallel buses, a plurality of first switches and at least one second switch, wherein the number of the parallel buses is consistent with that of the overcharge terminals; each parallel bus is connected to an output bus of at least one power supply unit in the plurality of power supply modules through a first switch, and the output bus of each power supply unit is only connected to one parallel bus; any two parallel buses are connected through a second switch; the power supply unit connected with each overcharge terminal and the power supply units which are not connected with other overcharge terminals share a parallel bus; the charging system can reduce the number of direct current switches and simplify the control logic on the premise of meeting the charging requirement.

    本发明公开了一种大功率超充快充双用直流充电系统,其包括多个充电终端、若干供电模组、若干第一投切组件、一第二投切组件和一充电控制模块,其中第二投切组件包括与超充终端数量一致的并联总线、若干第一开关和至少一个第二开关;每一并联总线均通过第一开关分别连接至多个供电模组中的至少一个供电单元的输出总线,且每一供电单元的输出总线仅连接至一并联总线;任意两个并联总线之间通过第二开关连接;每一超充终端连接的供电单元,不与其他超充终端连接的供电单元共用一并联总线;该充电系统可在满足充电需求的前提下,减少直流开关数量,简化控制逻辑。
