The invention relates to a storage battery charging method, device and equipment and a storage medium, and relates to the technical field of automobiles. The method comprises the steps that when a first preset duration is passed after the whole vehicle is powered off, the first environment temperature T1 and the first voltage U1 of a low-voltage storage battery of the vehicle are obtained through a battery detection unit of the vehicle; according to the first environment temperature T1 and the first voltage U1 of the low-voltage storage battery, the state of charge SOC of the low-voltage storage battery is determined through a vehicle body control unit BCM of the vehicle; when it is determined that the SOC of the low-voltage storage battery is smaller than a first preset electric quantity threshold value, the high-voltage storage battery charges the low-voltage storage battery through a direct-current converter DCDC, and the first preset electric quantity threshold value is the SOC of the to-be-charged state corresponding to the low-voltage storage battery. Therefore, the low-voltage storage battery can be charged, the requirement for long-term storage of the whole vehicle is met, and the situation that the SOC of the low-voltage storage battery is determined through storage battery sensors which are high in cost and not configured for many vehicles is avoided.

    本申请涉及一种蓄电池补电方法、装置、设备及存储介质,涉及汽车技术领域。该方法包括:在车辆整车下电后经过第一预设时长时,通过车辆的电池检测单元获取车辆的低压蓄电池的第一环境温度T1和第一电压U1;根据低压蓄电池的第一环境温度T1和第一电压U1,通过车辆的车身控制单元BCM确定低压蓄电池的荷电状态SOC;当确定低压蓄电池的SOC小于第一预设电量阈值时,高压蓄电池通过直流变换器DCDC对低压蓄电池进行补电,第一预设电量阈值为低压蓄电池对应的待补电状态的SOC。由此,可以对低压蓄电池补电,满足整车的长期存放,避免通过成本较高、并且许多车辆未配置的蓄电池传感器确定低压蓄电池的SOC。
