The embodiment of the invention provides a battery pack fault diagnosis method and device, computing equipment and a storage medium. The battery pack fault diagnosis method comprises the following steps: acquiring state characteristic data of a battery cell in a battery pack, wherein the state characteristic data comprises voltage data and temperature data; performing data analysis on the voltage data and the temperature data to determine whether the voltage data and the temperature data are normal data; and under the condition that one of the voltage data and the temperature data is normal data and the other is abnormal data, judging that the flexible circuit board corresponding to the abnormal data is a fault circuit board. By adopting the method provided by the embodiment of the invention, the fault of the flexible circuit board can be identified on the premise of avoiding the disassembly test of each component in the battery pack.

    本公开实施例提供一种电池包故障诊断方法、装置、计算设备和存储介质。电池包故障诊断方法包括:获取电池包中电芯的状态特征数据,状态特征数据包括电压数据和温度数据;对电压数据和温度数据分别进行数据分析,确定二者是否为正常数据;在电压数据和温度数据之一为正常数据并且另一为非正常数据的情况下,判定与非正常数据对应的柔性电路板为故障电路板。采用本实施例提供的方法,可以对避免对电池包中各个部件进行拆解测试的前提下,识别出柔性电路板故障。
