The invention provides a system and a method for charging an automobile storage battery, the system comprises a storage battery, a vehicle controller, a power supply loop and a charging device, and the charging device comprises an auxiliary power supply. The method comprises the steps that a charging device and a vehicle controller are electrically connected, an auxiliary power source of the charging device starts to output power to the vehicle controller, meanwhile, the power is output to a storage battery through a power supply loop, the vehicle controller judges whether a charging triggering condition is met or not, and when the charging triggering condition is met, the charging process of the storage battery is started; and after the charging process is finished, the vehicle controller informs the charging device of stopping the output of the auxiliary power supply, and charging of the storage battery is stopped. The problem of power shortage of the vehicle storage battery is solved, external power connection is not needed, and risks of short circuit and reverse connection are avoided.

    本发明提供一种为汽车蓄电池补电的系统和方法,系统包括:蓄电池、车辆控制器、供电回路和充电装置,充电装置包括辅助电源。方法为:电性连接充电装置与车辆控制器,充电装置的辅助电源开始输出给车辆控制器供电,同时通过供电回路输出至蓄电池,车辆控制器判断是否满足补电触发条件,当补电触发条件成立则进入蓄电池的补电流程,补电流程结束后车辆控制器通知充电装置停止辅助电源的输出,停止对蓄电池的补电。本发明解决车辆蓄电池亏电问题,无需外部搭电,且无短路和反接的风险。
