The invention relates to the technical field of vehicles, in particular to a vehicle storage battery charging method and device.The method comprises the steps that whether a vehicle is in an engine shutdown working condition or not is detected; when it is detected that the vehicle is in the engine shutdown working condition, the actual voltage of a vehicle storage battery is collected, and the minimum voltage threshold value of the vehicle storage battery is determined according to the environment temperature of the environment where the vehicle is located; whether the actual voltage is lower than the minimum voltage threshold value or not is judged, and if the actual voltage is lower than the minimum voltage threshold value, a power battery of the vehicle is controlled to charge a storage battery of the vehicle. Therefore, the problems that in the prior art, the voltage state of the storage battery can only be detected within the set time, the voltage state of the storage battery cannot be detected in real time, the real-time performance of detection is reduced, the voltage of the storage battery cannot be detected from multiple aspects, the risk of power shortage of the storage battery is increased, and the service life of the storage battery is shortened are solved.

    本申请涉及车辆技术领域,特别涉及一种车辆蓄电池的充电方法及装置,其中,方法包括:检测车辆是否处于发动机停机工况;在检测到车辆处于发动机停机工况时,采集车辆蓄电池的实际电压,并根据车辆所处环境的环境温度确定车辆蓄电池的最小电压阈值;判断实际电压是否低于最小电压阈值,其中,如果实际电压低于最小电压阈值,则控制车辆的动力电池为车辆蓄电池充电。由此,解决了相关技术中仅能在规定时间内检测蓄电池电压状态,无法实时检测蓄电池的电压状态,降低了检测的实时性,并且无法从多方面对蓄电池的电压进行检测,增加蓄电池亏电的风险,降低了蓄电池的使用寿命的问题。
