The embodiment of the invention provides a vehicle-mounted battery management system and method. The vehicle-mounted battery management system comprises a vehicle-mounted battery, a battery managementmodule connected with the vehicle-mounted battery and a generator connected with the vehicle-mounted battery, the vehicle-mounted battery is used for supplying power to a vehicle starter and/or a vehicle-mounted electric appliance; the battery management module is used for acquiring the battery capacity of the vehicle-mounted battery; and a vehicle engine is started to drive the generator to charge the vehicle-mounted battery under the condition that the vehicle engine is not in a working state and the difference value between the battery electric quantity and the starting electric quantity of the vehicle starter is not greater than a starting threshold value. By means of the vehicle-mounted battery management system and method, the generator can be started to supplement power to the vehicle-mounted battery when the electric quantity of the vehicle-mounted battery is low, and the situation that the vehicle starter cannot be started due to the fact that the electric quantity of the vehicle-mounted battery is exhausted is avoided.

    本说明书实施例提供一种车载电池管理系统及方法。其中,所述车载电池管理系统包括车载电池、连接所述车载电池的电池管理模块和连接所述车载电池的发电机;所述车载电池,用于向车辆起动机和/或车载电器供电;所述电池管理模块,用于获取所述车载电池的电池电量;在汽车发动机未处于工作状态且所述电池电量与所述车辆起动机的启动电量的差值不大于启动阈值的情况下,启动汽车发动机以使所述汽车发动机带动所述发电机向所述车载电池充电。通过上述车载电池管理系统及方法,可以在车载电池的电量较低时启动发电机为车载电池补电,避免车载电池电量消耗殆尽而无法启动汽车起动机的情况。
