The invention provides a low-electric-quantity charging control system and method for a low-voltage storage battery. The control system comprises a battery sensor used for monitoring the residual electric quantity value of the low-voltage storage battery, a judgment module at least used for judging the relation between the residual electric quantity value and a low electric quantity threshold value, a vehicle body controller and a whole vehicle controller used for controlling the power module to charge the low-voltage storage battery. According to the control method, the elements are used for controlling low-power charging of the low-voltage storage battery. According to the invention, the battery sensor is adopted to accurately monitor the residual electric quantity value, the battery precision, the charging current and other signals of the low-voltage storage battery, so that the electric quantity monitoring accuracy and the charging timeliness of the low-voltage storage battery under the conditions of battery aging, external environment change and the like are improved, meanwhile, the static energy consumption of vehicle components can be reduced, and the low-voltage storage battery is protected.

    本发明提供了一种低压蓄电池低电量充电控制系统及控制方法。控制系统包括:用于监测低压蓄电池的剩余电量值的电池传感器、至少用于判断剩余电量值与低电量阈值关系的判断模块和车身控制器以及用于控制电源模块对低压蓄电池进行充电的整车控制器。控制方法利用上述元件实现对低压蓄电池低电量充电的控制。本发明采用了电池传感器来准确监测低压蓄电池的剩余电量值、电池精度、充电电流等信号,提高了在电池老化、外界环境变化等情况下对低压蓄电池的电量监测的准确性以及充电的及时性,同时还能够降低车辆元器件的静态能耗,保护低压蓄电池。
