The invention discloses an early warning method and device for a vehicle and a power battery of the vehicle and a storage medium, and the method comprises the steps: dividing the vehicle into a plurality of vehicle types according to the throughput capacity of the power battery and the geographic position of the vehicle, and determining the reference average temperature slope of the power battery according to the vehicle types, and obtaining the average temperature slope of the power battery of the target vehicle in the first preset interval, and determining early warning information of the target vehicle according to the average temperature slope of the target vehicle in the first preset interval and the reference average temperature slope of the vehicle type of the target vehicle in the first preset interval. According to the early warning method, the battery operation state and the geographic position of the vehicle are combined to be divided into multiple vehicle types, the change rule of the vehicle operation state is judged according to the average temperature slope and the vehicle type of the target vehicle and the reference average temperature slope corresponding to the target vehicle, the abnormal condition of the battery can be recognized in advance, and the early warning accuracy is improved. And safety early warning of the battery is realized.

    本发明公开了一种车辆及其动力电池的预警方法、预警装置以及存储介质,方法包括:根据动力电池的吞吐容量和车辆所处地理位置划分为多个车辆类型,根据车辆类型确定动力电池的参考平均温度斜率,获取目标车辆的动力电池在第一预设区间内的平均温度斜率,根据目标车辆在第一预设区间内的平均温度斜率与目标车辆所属车辆类型在第一预设区间内的参考平均温度斜率确定目标车辆的预警信息。本发明的预警方法,结合电池运行状态以及车辆所处地理位置划分为多个车辆类型,根据目标车辆的平均温度斜率和所属车辆类型以及目标车辆对应的参考平均温度斜率,判断车辆运行状态的变化规律,能够提前识别电池的异常情况,实现电池的安全预警。
