The invention provides a storage battery electric quantity management method and device, a vehicle and a storage medium, and the method comprises the steps: delaying a first preset time to obtain the remaining electric quantity, lower limit electric quantity and power consumption of a storage battery when determining that a charging control unit meets a sleep condition; judging whether the vehicle can be normally started after stopping running for a second preset time or not according to the residual electric quantity, the lower limit electric quantity and the power consumption of the storage battery, and if yes, controlling the charging control unit to enter a dormant state; otherwise, the charging control unit controls the direct-current converter to be started to charge the storage battery. According to the invention, there is no need to additionally add a clock chip or newly add a wake-up signal, the electric quantity management of the storage battery can be realized only through the remaining electric quantity and the lower limit electric quantity of the storage battery and the power consumption during the stop of the vehicle, and the management cost of the storage battery is increased, thereby greatly saving the design cost of a hardware circuit during the energy management of the storage battery. And the problem that the vehicle cannot be started due to power shortage of the storage battery under most conditions is avoided.

    本发明提出一种蓄电池电量管理方法及装置、车辆和存储介质,方法包括:确定充电控制单元满足休眠条件时,延迟第一预设时间获取蓄电池的剩余电量、下限电量及耗电量;根据蓄电池的剩余电量、下限电量及耗电量判断车辆在停止运行第二预设时间后能否正常启动,若是,则控制充电控制单元进入休眠状态;否则,充电控制单元控制直流转换器开启为所述蓄电池充电。本发明无需额外增加时钟芯片,或者,新增唤醒信号,仅通过蓄电池剩余电量、下限电量及车辆停止运行期间的耗电量即可实现对蓄电池的电量管理增加蓄电池管理成本,从而极大的节约了蓄电池能量管理时的硬件电路设计成本,同时,避免了大多数情况下车辆因的蓄电池亏电而无法启动的问题。
