The invention provides a charging system, a charging control method and a charging pile, and the system comprises a first power module which comprises a plurality of first power units which are sequentially and electrically connected through a power switch module, and form a totally-enclosed or semi-enclosed structure; and the second power module comprises a plurality of second power units which are electrically connected in sequence through the power switch module, and at least part of the second power units are electrically connected with at least one first power unit through the power switch module. According to the invention, the plurality of first power units are electrically connected in sequence to form a totally-enclosed or semi-enclosed structure and form the power output port, and the plurality of second power units are electrically connected in sequence, so that at least part of the second power units are electrically connected with at least one first power unit and form the power output port. Therefore, the requirement of the charging system for increasing the charging power modules can be met, the number of the power switches can be reduced, the cost of the whole charging system is reduced, and the size is reduced.
本申请提供一种充电系统、充电控制方法及充电桩,其中,充电系统包括第一功率模块,包括多个第一功率单元分别通过功率开关模块依次电连接,并围成全封闭或者半封闭的结构;第二功率模块,包括多个第二功率单元分别通过功率开关模块依次电连接,至少部分第二功率单元分别通过功率开关模块与至少一个第一功率单元电连接。本申请将多个第一功率单元依次电连接围成全封闭或者半封闭的结构并形成功率输出端口,将多个第二功率单元依次电连接,使至少部分第二功率单元与至少一个第一功率单元电连接并形成功率输出端口,从而既能满足充电系统对充电功率模块增加的需求,又能减小功率开关数量,同时使整个充电系统降低了成本,减小了体积。
