The invention discloses a fault battery detection method, device and equipment and a computer storage medium, and relates to the field of computers. The invention can be applied to the field of electric vehicles. According to the specific implementation scheme, the method comprises the following steps: acquiring voltage data of each single battery within a set time length after a fault occurs; carrying out principal component analysis on the voltage data of each single body of the battery in a set duration when a fault occurs to obtain principal component data of each single body of the battery in the set duration; carrying out clustering analysis on the principal component data, meeting the condition within the set duration, of all the single bodies of the battery, and obtaining categories divided for all the single bodies according to the principal component data; and determining whether each single body is a faulty single body or not according to the category.

    本申请公开了故障电池检测方法、装置、设备及计算机存储介质,涉及计算机领域。本申请可应用于电动车辆领域。具体实现方案为:获得电池的各个单体在故障发生后的设定时长内的电压数据;对所述电池的各个单体在故障发生时的设定时长内的电压数据进行主成分分析,获得所述电池的各个单体在所述设定时长内的主成分数据;对所述电池的各个单体在所述设定时长内满足条件的主成分数据进行聚类分析,获得根据所述主成分数据对所述各个单体划分的类别;根据所述类别,确定所述各个单体是否为故障单体。
