The invention discloses a vehicle power shortage control method and system. The method comprises the steps that whether a vehicle is in a dormant state or not is judged; if not, whether the vehicle is in the dormant state or not continues to be judged; if yes, a storage battery controller is awakened at a preset time interval, current storage battery information of the vehicle is obtained through the storage battery controller, and whether the state of the storage battery is abnormal or not is judged accordingly; if yes, state information of a plurality of loads of the vehicle is collected and stored, and operation of the loads is controlled; the storage battery information comprises a quiescent current value and a storage battery state value, and the condition for judging the state abnormity of the storage battery comprises at least one abnormity of the quiescent current value and the storage battery state value; if the static current value is greater than the current threshold value, judging that the static current value is abnormal; and if the storage battery state value is within the preset abnormal threshold range, judging that the storage battery state value is abnormal. When the storage battery is lack of electricity, the electricity lack problem can be positioned, corresponding measures are taken to reduce the risk of electricity lack of the storage battery, and electric energy waste is avoided.

    本发明公开了一种车辆亏电控制方法及系统,方法包括判断车辆是否处于休眠状态;若否,则继续判断车辆是否处于休眠状态;若是,则以预设的时间间隔唤醒蓄电池控制器,通过蓄电池控制器获取车辆当前的蓄电池信息,依此判断蓄电池的状态是否异常;若异常,则采集并存储车辆的多个负载的状态信息,并控制多个负载的运行;蓄电池信息包括静态电流值和蓄电池状态数值,判断蓄电池的状态异常的条件包括静态电流值和蓄电池状态数值中至少一种异常;若静态电流值大于电流阈值,则判断静态电流值异常;若蓄电池状态数值在预设异常阈值范围内,则判断蓄电池状态数值异常。当蓄电池亏电,能够定位亏电问题并采取相应措施降低蓄电池亏电的风险,避免电能浪费。
