The invention discloses a charging device, a charging method based on power matching and a charging pile. The charging device comprises a control unit, a first power distribution unit, a second power distribution unit and M power modules, wherein M is an integer greater than 1; n1 first power modules in the M power modules are connected with the first power distribution unit, N2 second power modules in the M power modules are connected with the second power distribution unit, and charging power provided by the N1 first power modules meets current flow parameters of the first power distribution unit. The charging power provided by the N2 second power modules meets the current through-flow parameter of the second power distribution unit, and the sum of N1 and N2 is smaller than or equal to M; the control unit can determine m target power modules from the M power modules and control the m target power modules to supply power, and the target power distribution unit connected with the m target power modules provides a power supply path for the m target power modules. The charging efficiency of the charging device is improved.

    一种充电装置、基于功率匹配的充电方法以及充电桩。该充电装置包括:控制单元、第一功率分配单元、第二功率分配单元和M个功率模块,M为大于1的整数;M个功率模块中的N1个第一功率模块与第一功率分配单元连接,M个功率模块中的N2个第二功率模块与第二功率分配单元连接,N1个第一功率模块提供的充电功率满足第一功率分配单元的电流通流参数,N2个第二功率模块提供的充电功率满足第二功率分配单元的电流通流参数,N1和N2之和小于或等于M;该控制单元可以从M个功率模块中确定m个目标功率模块,并控制m个目标功率模块供电,m个目标功率模块连接的目标功率分配单元为该m个目标功率模块提供供电通路。提高充电装置的充电效率。
