The invention relates to a low-voltage storage battery charging method and device, electronic equipment and a storage medium, and the method comprises the steps: detecting the battery state of a low-voltage storage battery once every first preset duration under the condition that a vehicle power supply is in a power-off state; if the battery state of the low-voltage storage battery represents that the electric quantity of the storage battery is smaller than a first preset threshold value, a vehicle body controller is awakened to obtain the environment temperature outside the vehicle; determining a charging strategy according to the ambient temperature outside the vehicle; and controlling a high-voltage battery management system to be powered on according to the charging strategy so as to charge the low-voltage storage battery through a high-voltage battery. According to the method, standby power consumption is saved, the charging strategy is determined according to the obtained external environment temperature, the high-voltage battery management system is controlled to be powered on according to the charging strategy so as to charge the low-voltage storage battery through the high-voltage battery, the problem of timely charging the low-voltage storage battery is solved, it is guaranteed that the power of the low-voltage storage battery meets the use requirement, and the service life of the low-voltage storage battery is prolonged. And the user experience is improved.

    本申请涉及一种低压蓄电池充电方法、装置、电子设备及存储介质,方法包括:在整车电源处于下电状态的情况下,每间隔第一预设时长检测一次低压蓄电池的电池状态;若所述低压蓄电池的电池状态表征蓄电池电量小于第一预设阈值,则唤醒车身控制器,以获取车外环境温度;根据所述车外环境温度确定充电策略;根据所述充电策略控制高压电池管理系统上电,以通过高压电池对所述低压蓄电池进行充电。该方法节省了待机电量消耗,根据获取的车外环境温度确定充电策略,根据充电策略控制高压电池管理系统上电以通过高压电池对低压蓄电池进行充电,解决了对低压蓄电池进行及时充电的问题,保证低压蓄电池电量满足使用需要,提高了用户体验。
