The invention relates to a battery early warning method and device, equipment and a storage medium. The battery early warning method comprises the steps that the current heat exchange power of a battery system of a vehicle is calculated according to current driving data of the vehicle; determining at least one reference heat exchange power in a pre-constructed heat exchange power library according to the calculated current charge-discharge cycle number of the battery system; and if the current heat exchange power and the at least one reference heat exchange power meet the preset condition, an early warning prompt is generated. According to the method provided by the invention, the current heat exchange power and the determined at least one reference heat exchange power are compared and analyzed, so that the abnormity of the heat management hardware in the battery system of the vehicle can be early warned in time, and a guarantee is provided for the effective work of the battery system to a certain extent; and the safety of the electric automobile in the driving process is further improved.

    本公开涉及一种电池预警方法、装置、设备和存储介质。电池预警方法包括:根据车辆的当前行驶数据计算所述车辆的电池系统的当前换热功率;根据计算的所述电池系统的当前充放电循环次数在预先构建的换热功率库中确定至少一个参考换热功率;若所述当前换热功率与所述至少一个参考换热功率满足预设条件,则生成预警提示。本公开提供的方法通过对当前换热功率和确定的至少一个参考换热功率进行比对分析,能够及时对车辆的电池系统中的热管理硬件异常进行预警,一定程度上为电池系统有效工作提供了保障,进一步提高了电动汽车在行驶过程中的安全性。
