The invention discloses a storage battery charging method and device, a vehicle and a storage medium, and the method comprises the steps: detecting the current environment temperature of the environment where a storage battery is located, and the current voltage and the current charge state of the storage battery according to a charging detection instruction, and judging whether the current is smaller than or equal to a first preset threshold value matched with the current environment temperature and the current voltage; and when the current environment temperature is less than or equal to the first preset threshold value, calculating a target charging duration of the storage battery from the current charging to a second preset threshold value according to the current environment temperature, and continuously charging the storage battery for the target charging duration. The problems that charging and consumption of the storage battery cannot be balanced due to the influence of the environment temperature on the storage battery, the standing time of the whole vehicle does not reach the intelligent charging purpose and the like are solved, the real-time cost of the charging method is reduced, and power voltage electric quantity loss caused by long-time charging when the storage battery is quickly charged under the normal temperature condition is avoided; and when the storage battery is charged slowly at a low temperature, the capacity of the storage battery is not supplemented to a target value due to insufficient charging time.

    本申请一种蓄电池的补电方法、装置、车辆及存储介质,包括:根据补电检测指令检测蓄电池所处环境的当前环境温度和蓄电池的当前电压和当前荷电状态,判断当前是否小于或等于由当前环境温度和当前电压匹配的第一预设阈值;在当前小于或等于第一预设阈值时,根据当前环境温度计算蓄电池由当前补电至第二预设阈值的目标补电时长,为蓄电池补电持续目标补电时长。解决由于环境温度对蓄电池的影响,导致蓄电池的补电和消耗无法平衡,整车静置时间没有达到智能补电目等问题,降低了补电方法实时成本,避免了常温情况蓄电池充电快时因长时间充电导致动力电压电量损耗,低温情况蓄电池充电慢时因充电时间不够导致蓄电池容量没有补充到目标值的情况。
