The invention relates to the technical field of computers, and discloses a method and device for identifying an abnormal battery cell, computer equipment and a storage medium, and the method comprises the steps: obtaining the total equalization duration of each battery cell in a plurality of battery cells of a target battery pack in a target time period; determining a reference total equalization duration according to the total equalization duration of each battery cell in the target time period, and calculating a difference value between the total equalization duration of each battery cell in the target time period and the reference total equalization duration; when the difference value between the total equalization duration of a target battery cell in the multiple battery cells in the target time period and the reference total equalization duration is larger than a total equalization duration deviation threshold value, the target battery cell is determined as an abnormal battery cell, and the target battery cell is any one battery cell in the multiple battery cells.

    本公开涉及计算机技术领域,公开了识别异常电芯的方法、装置、计算机设备及存储介质,该方法包括:获取目标电池包的多个电芯中每个电芯的在目标时间段的总均衡时长;根据所述每个电芯的在目标时间段的总均衡时长,确定参考总均衡时长,以及计算所述每个电芯的在目标时间段的总均衡时长与所述参考总均衡时长的差值;当所述多个电芯中目标电芯的在目标时间段的总均衡时长与所述参考总均衡时长的差值大于总均衡时长偏差阈值时,将目标电芯确定为异常电芯,其中,所述目标电芯为所述多个电芯中任意一个电芯。
