The embodiment of the invention discloses a battery charging cut-off charge state determination method and device, electronic equipment and a medium. The battery charging cut-off charge state determination method comprises the steps of obtaining a first real-time temperature of a position environment where a battery is located and a second real-time temperature of a weather forecast of an area where the vehicle is charged in a charging process of the vehicle; calculating the temperature difference value of the vehicle in the charging process according to the first real-time temperature and the second real-time temperature; determining the highest environment temperature and the lowest environment temperature experienced by the battery based on the temperature difference value and an air temperature prediction curve; determining a cut-off state of charge of the battery during this charging based on the highest ambient temperature and the lowest ambient temperature experienced by the battery. According to the technical scheme, attenuation of the service life of the battery can be slowed down, and the service life of the battery is prolonged.

    本发明实施例公开了一种电池充电截止电荷状态确定方法、装置、电子设备及介质。该电池充电截止电荷状态确定方法包括:获取车辆在充电过程中的电池所在位置环境的第一实时温度以及车辆充电所在区域天气预报的第二实时温度;根据第一实时温度以及第二实时温度计算车辆在充电过程中温度差值;基于温度差值以及气温预测曲线确定电池经历的最高环境温度和最低环境温度;基于电池经历的最高环境温度和最低环境温度确定电池在此次充电过程中的截止电荷状态。本发明实施例的技术方案,可以减缓电池寿命的衰减,提高电池的使用寿命。
