The invention is suitable for the technical field of vehicles, and provides a battery charging upper limit value adjusting method and device, a vehicle and a storage medium. The battery charging upper limit value adjusting method comprises the steps that after charging of a vehicle battery is finished, the current charging upper limit value of the battery, the charging amount of the battery, the use power of the battery and a battery flag bit are obtained; if the current charging upper limit value is greater than or equal to a first preset limit value, the charging amount is less than a preset charging amount, the use power is less than a preset power and the battery flag bit is a first flag bit, adding a preset value to the accumulated number of times; and if the accumulated number of times reaches the preset number of times, sending prompt information for reminding the user to reduce the charging upper limit value. After the user receives the prompt information, the charging upper limit value of the battery can be reduced, on the premise that the power requirement of the user is met, it can be avoided that the battery keeps high SOC for a long time, the attenuation speed of the battery is slowed down, the service life of the battery is prolonged, meanwhile, the probability of battery thermal runaway is reduced, and the safety of the vehicle is improved.

    本申请适用于车辆技术领域,提供了一种电池充电上限值调节方法、装置、车辆及存储介质。电池充电上限值调节方法包括:在车辆电池充电结束后,获取电池的当前充电上限值、电池的充电量、电池的使用功率以及电池标志位;若当前充电上限值大于或等于第一预设限值、充电量小于预设充电量、使用功率小于预设功率且电池标志位为第一标志位时,将累计次数增加预设值;若累计次数达到预设次数,发送用于提醒用户降低充电上限值的提示信息。用户接收到提示信息后可以降低电池的充电上限值,在满足用户功率需求的前提下,可以避免电池长期保持高SOC,减缓电池的衰减速度,延迟电池的使用寿命,同时降低电池热失控发生的概率,提高车辆的安全性。
