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 after the whole vehicle is powered off, the SOC of a low-voltage storage battery of the vehicle is obtained through a storage battery sensor of the vehicle after a first preset duration, and the power supply voltage of the low-voltage storage battery is lower than a preset voltage value; when it is determined that the SOC of the low-voltage storage battery is larger than a first preset electric quantity threshold value and smaller than a second preset electric quantity threshold value, the high-voltage storage battery charges the low-voltage storage battery through DCDC, the first preset electric quantity threshold value is the lowest SOC when the low-voltage storage battery meets the whole vehicle power-on requirement, and the second 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 problem that the whole vehicle cannot be charged through the low-voltage storage battery, and then the low-voltage storage battery cannot be charged is solved.

    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,通过车辆的蓄电池传感器获取车辆的低压蓄电池的SOC,低压蓄电池的供电电压低于预设电压值;当确定低压蓄电池的SOC大于第一预设电量阈值且小于第二预设电量阈值时,高压蓄电池通过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满足整车上电的最低SOC,第二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,避免无法通过低压蓄电池为整车上电,进而无法对低压蓄电池补电的问题。
