The invention discloses a battery temperature early warning method, device and equipment and a storage medium, and belongs to the technical field of vehicles. The method comprises the steps of firstly determining a target working condition corresponding to a target vehicle, then obtaining a reference feature and a plurality of cooling intervals corresponding to the target working condition, determining a target feature distance between a target feature of the target vehicle and the reference feature, and determining a target cooling interval to which the target feature distance belongs from the plurality of cooling intervals, and when the target cooling interval is the early warning interval, performing early warning. According to the method, the efficiency of the cooling system is estimated by determining the deviation degree between the target feature and the reference feature, the efficiency is compared with the divided cooling intervals, abnormal early warning of the battery temperature is indirectly achieved, and therefore the early warning accuracy is improved.

    本申请公开了一种电池温度预警方法、装置、设备及存储介质,属于车辆技术领域。该方法先确定目标车辆对应的目标工况,然后获取目标工况对应的基准特征和多个降温区间,确定目标车辆的目标特征与基准特征之间的目标特征距离,从多个降温区间中确定目标特征距离所属的目标降温区间,在目标降温区间为预警区间的情况下,进行预警。该方法通过确定目标特征与基准特征之间的偏离程度来预估冷却系统的效率,并与划分的降温区间进行对比,间接实现电池温度的异常预警,从而提高预警的准确性。
