The embodiment of the invention provides a battery early warning method, device and equipment and a readable storage medium. The method comprises the steps of obtaining a preset electric quantity analysis interval of a battery; in the process that the battery is charged to the preset electric quantity analysis interval for the ith time, corresponding charging voltages of the battery at at least two moments are recorded, and i is a positive integer; obtaining the voltage difference of the charging voltage corresponding to at least two moments, and obtaining the charging duration of the battery in a preset electric quantity analysis interval; determining voltage difference change rate data of the battery on the basis of the voltage difference and the charging duration respectively corresponding to the battery in the at least two charging processes; and generating early warning information of the battery under the condition that the differential pressure change rate data meets the early warning requirement. And the accuracy and the reliability of determining the voltage difference are effectively improved.

    本申请实施例提供一种电池预警方法、装置、设备及可读存储介质。该方法包括:获取电池的预设电量分析区间;在电池第i次充电至预设电量分析区间的过程中,记录电池在至少两个时刻对应的充电电压,i为正整数;获取至少两个时刻对应的充电电压的电压压差,以及,获取所述电池在预设电量分析区间的充电时长;基于电池在至少两次充电过程中分别对应的电压压差和充电时长,确定电池的压差变化率数据;在压差变化率数据达到预警要求的情况下,生成电池的预警信息。有效提高确定电压压差的准确性以及可靠性。
