The invention relates to the technical field of charging control, and discloses a direct-current charger bus preprocessing charging control method and electronic equipment, and the method comprises the steps: a charger receives a preprocessing message sent by a vehicle BMS, and starts timing; the air conditioner is started, and the charger enters a pretreatment charging process after 10 min; the pre-processing charging process comprises the following steps: detecting the single voltage Vc and the residual charging duration of the battery; obtaining a single upper limit cut-off voltage Vs; if the single voltage is Vclt; when the voltage is 3.56 V, charging is carried out according to the BMS requirement of the vehicle; when Vc is greater than or equal to 3.56 V, entering a dynamic output adjustment strategy based on single battery voltage rise rate control, and controlling the charging current so as to control the charging time; when a vehicle BMS charging stopping command is received, output is stopped, or when the departure time Td is reached, the charger stops output when receiving a charging stopping command of the cloud platform, and the charging process is completed. According to the method, charging in the preprocessing process is achieved in the mode that the charger dynamically controls the charging current, it is guaranteed that the battery is 100% SOC during departure, and the method is more intelligent and reliable.

    本发明涉及充电控制技术领域,公开了一种直流充电机大巴车预处理充电控制方法及电子设备,包括:充电机收到车辆BMS发送的预处理消息,开始计时;空调开启,10min后充电机进入预处理充电流程;预处理充电流程包括:检测电池的单体电压Vc和剩余充电时长;获取单体上限截止电压Vs;若单体电压Vc<3.56V时,按车辆BMS需求进行充电;当Vc≥3.56V时,进入基于电池单体电压上升率控制的动态输出调整策略,控制充电电流从而控制充电时间;当收到车辆BMS停止充电命令时停止输出,或者在到达发车时间Td时,充电机收到云平台停止充电命令时停止输出,完成充电过程。本发明由充电机动态控制充电电流的方式来实现预处理过程的补电,保证发车时电池为100%SOC,更加智能和可靠。
