The invention belongs to a topological structure, and provides a charging pile power distribution topology, a cabinet combination system, a control method of the cabinet combination system and a controller aiming at the technical problems that the expandability is limited, the calling logic is complex and the number of switches is large in a current group charging direct current charging pile power distribution scheme. Comprising at least one output contactor, a plurality of power modules and a plurality of parallel contactors. The power modules are connected with the charging gun, the output contactors are arranged between the power modules and the charging gun, the power of the power modules is equal, the power modules are connected in sequence, and the parallel contactors are arranged between the adjacent power modules to form an outer ring structure. In the outer ring structure, every three power modules are connected to form at least one triangular inner ring structure; or every four power modules are connected to form at least one square inner ring structure; or every six power modules are connected to form at least one hexagonal inner ring structure.
本申请属于一种拓扑结构,针对当前群充直流充电桩的功率分配方案,存在可扩展性受限、调用逻辑复杂和开关数量多的技术问题,提供一种充电桩功率分配拓扑、并柜系统及其控制方法、控制器,包括至少一个输出接触器、多个功率模块和多个并联接触器。功率模块与充电枪相连,输出接触器设置于功率模块与充电枪之间,各功率模块的功率相等,多个功率模块依次相连,相邻功率模块之间均设置有并联接触器,形成外环结构。在外环结构内,每三个功率模块相连,形成至少一个三角形内环结构;或者每四个功率模块相连,形成至少一个正方形内环结构;或者每六个功率模块相连,形成至少一个六边形内环结构。
