The invention provides a charging module calling method for a direct-current flexible split charging pile, the method is used for a matrix type charging system, the charging pile comprises a charging gun, a control box and a charging module, the charging gun is connected with a vehicle, and the method comprises the following steps: in a starting stage, the charging gun initiates a request instruction for calling the corresponding charging module; insulation detection is carried out on the corresponding charging module, and first pre-charging is carried out on the corresponding charging module and the vehicle battery. In the charging stage, when the required current is greater than the corresponding charging module, performing second pre-charging; in the second pre-charging process, the required number of the charging modules and the idle charging modules are firstly judged according to the required current, and then whether the connection control box corresponding to the required number of the charging modules is idle or not is judged; and closing a contactor of a control box associated with the charging module to charge the vehicle. And in the charging ending stage, the contactor is switched off when it is detected that the vehicle reaches the set SOC value. The service life of the vehicle electrical system and the battery is prolonged through the method.

    本申请提供了一种关于直流柔性分体充电桩调用充电模块的方法,用于矩阵式充电系统,充电桩包括充电枪、控制盒和充电模块,充电枪与车辆连接,方法步骤包括:在启动阶段中,充电枪发起调用对应充电模块的请求指令,对应充电模块进行绝缘检测且对应充电模块和车辆电池进行第一预充。在充电阶段中,在需求电流大于对应充电模块,进行第二预充;在第二预充中,根据需求电流先判断充电模块的需求数量和空闲的充电模块,再判断调用充电模块需求数量对应连接控制盒是否空闲;闭合充电模块相关联控制盒的接触器,对车辆进行充电。在充电结束阶段,检测车辆达到设定的SOC值,断开接触器。通过上述方法提高车辆电气系统和电池的寿命。
