The invention provides a system and method for charging an automobile storage battery. According to the system, a charging device is electrically connected with a DCDC, a BECM and a VCU, the charging device supplies power to the VCU, the BECM and the DCDC, the VCU starts the charging process of the storage battery when it is judged that the storage battery is lack of electricity, and the charging device is disconnected after charging is completed. The problems that when the problem of power shortage of the storage battery is solved in an external power connection mode, a power connection wire of the storage battery needs to be led out, the power connection requirement conditions are more, operation is inconvenient, the risks of short circuit and reverse connection exist, and a circuit or vehicle equipment is prone to being burnt down are solved.

    本发明提供一种为汽车蓄电池补电的系统和方法,本发明的系统将充电装置分别与DCDC、BECM和VCU电性连接,充电装置向VCU、BECM和DCDC供电,VCU判断在蓄电池亏电时启动蓄电池的补电流程,补电完成后断开充电装置。本发明解决了以外部搭电的方式解决蓄电池亏电问题时,需引出蓄电池搭电线,搭电要求的条件较多,操作不方便,且存在短接和反接的风险,易烧毁线路或车辆设备的问题。
