The invention provides a method and device for detecting abnormity of a vehicle battery, electronic equipment and a medium, and the method comprises the steps: determining a theoretical voltage difference between a current single battery cell and each remaining single battery cell for any current single battery cell in a battery pack; determining an actual voltage difference between the current single cell and each residual single cell; detecting the current single battery cell according to each theoretical voltage difference and each actual voltage difference; therefore, the characteristics of the single battery cells are considered, so that when the voltage difference between the current single battery cell and each residual single battery cell is determined, the difference between all the single battery cells in the battery pack is found, and the abnormal battery cells are detected by comparing a plurality of theoretical voltage differences with a plurality of actual voltage differences; the big data detection mode can accurately identify the battery cell with abnormal discharge, timely early warning is realized, and the driving safety can be improved.

    本发明提供了一种检测车辆电池异常的方法、装置、电子设备及介质,方法包括:针对电池包中的任一当前单体电芯,确定所述当前单体电芯与每个剩余单体电芯之间的理论电压差;确定所述当前单体电芯与所述每个剩余单体电芯之间的实际电压差;根据各所述理论电压差和各所述实际电压差对所述当前单体电芯进行检测;如此,本发明考虑到单体电芯各自的特性,因此当确定出当前单体电芯与每个剩余单体电芯之间的电压差异,相当于是找出了电池包中所有单体电芯之间的差异,通过比较多个理论电压差和多个实际电压差对异常电芯进行检测,这种大数据的检测方式可准确识别出具有异常放电的电芯,及时预警,有助于提高行车安全。
