The invention discloses a charging system and a charging control method. The charging system comprises a controller, a plurality of charging modules, a plurality of charging guns and a plurality of power switches, the two charging modules are connected through corresponding power switches; the charging gun is connected with the charging module; the number of the charging guns is less than or equal to that of the charging modules; the controller is used for determining the number N of needed charging modules according to the charging demand power, N is larger than or equal to 2, the number of switches passing through the path from each charging module to the charging gun in the N charging modules is obtained, and the charging module combination with the minimum sum of the number of the switches corresponding to the N charging modules is selected for charging. As the power switches need to consume energy and can generate heat when being closed, in order to prolong the service life of the power switches and reduce the loss of the whole charging pile, a path with the fewest power switches is selected as a charging path, and the less the number of the power switches controlled by the controller is, the simpler and more flexible control is.
本申请公开了一种充电系统及充电控制方法,包括:控制器、多个充电模块、多个充电枪和多个功率开关;两个充电模块之间通过对应的功率开关连接;充电枪连接充电模块;充电枪的数量小于等于充电模块的数量;控制器,用于根据充电需求功率确定需要的充电模块的数量N,N大于等于2,获得N个充电模块中每个充电模块到充电枪的路径上经过的开关数量,选择N个充电模块对应的开关数量之和最小的充电模块组合来充电。由于功率开关闭合需要消耗能量,而且会发热,因此,为了提高功率开关的寿命,同时降低整个充电桩的损耗,选择功率开关最少的路径作为充电路径,并且控制器控制的功率开关数量越少,控制越简单灵活。
