The invention provides a battery abnormal self-discharge early warning method and system, electronic equipment and a storage medium, and the method comprises the steps: obtaining a plurality of monomer voltage extreme values, monomer charge state extreme values and adjacent data time intervals in a current working condition period of a vehicle battery system based on the working condition information, structure information and consistency information of the vehicle battery system; calculating the self-discharge capacity, the self-discharge energy and the average self-discharge current value of the vehicle battery system based on the monomer voltage extreme value, the monomer state-of-charge extreme value and the adjacent data time interval; according to the self-discharge capacity, the self-discharge energy and the average self-discharge current value, whether self-discharge occurs in the vehicle battery system or not is judged; and carrying out battery safety early warning based on a judgment result. By calculating the self-discharge capacity, the self-discharge energy and the average self-discharge current value of the vehicle battery system, whether the vehicle is subjected to self-discharge or not is judged, so that the self-discharge condition of the vehicle battery system is pre-warned, and the safety of the vehicle battery system is greatly improved.

    本发明提供的一种电池异常自放电预警方法、系统、电子设备及存储介质,方法包括:基于车辆电池系统的工况信息、结构信息和一致性信息,获取车辆电池系统当前工况周期内多个单体电压极值、单体荷电状态极值和相邻数据时间间隔;基于单体电压极值、单体荷电状态极值和相邻数据时间间隔,计算车辆电池系统的自放电容量、自放电能量和平均自放电电流值;根据自放电容量、自放电能量和平均自放电电流值判断车辆电池系统是否出现自放电;基于判断结果进行电池安全预警。本发明通过计算车辆电池系统的自放电容量、自放电能量和平均自放电电流值,判断车辆是否出现自放电,从而对车辆电池系统自放电情况预警,大大的提高了车辆电池系统的安全性。
