The invention relates to the technical field of new energy automobiles, in particular to a storage battery charging method and device, a vehicle and a storage medium, and the method comprises the steps that whether the vehicle enters a storage battery charging mode or not is recognized; if the vehicle enters the storage battery charging mode, the ambient temperature around the vehicle is detected, and charging starting time and charging allowing conditions of a storage battery are matched according to the ambient temperature; if the current time is the charging starting time and the storage battery meets the charging allowing condition, a power battery of the vehicle is controlled to charge the storage battery, and when the vehicle meets the charging exiting condition, the power battery is controlled to stop charging the storage battery so as to end charging. Therefore, the limitation caused by additional installation of an external sensor in the related technology is solved, and the problem that the vehicle storage battery is possibly fed due to the fact that the charging entering and exiting time is not accurately judged based on the environment temperature and the storage battery monitoring state, so that the service life of the storage battery is shortened, and the service life of the vehicle storage battery is prolonged is solved. And the user experience feeling is poor.

    本申请涉及新能源汽车技术领域,特别涉及一种蓄电池补电方法、装置、车辆及存储介质,其中,包括:识别车辆是否进入蓄电池补电模式;若车辆进入蓄电池补电模式,则检测车辆周围的环境温度,根据环境温度匹配蓄电池的补电开始时间和补电允许条件;若当前时间为补电开始时间,且蓄电池满足补电允许条件,则控制车辆的动力电池对蓄电池进行充电,并在车辆满足补电退出条件时,控制动力电池停止对蓄电池进行充电以结束补电。由此,解决了相关技术中加装外部传感器导致的局限性,以及并未基于环境温度和蓄电池监控状态准确判断出补电进入和退出时机导致车辆蓄电池可能由于未及时补电而出现馈电的情况,从而缩短了蓄电池的寿命,用户体验感较差等问题。
