The invention discloses a vehicle battery monomer consistency evaluation method, device and equipment and a storage medium, and the method comprises the steps: obtaining vehicle operation data, and screening out effective monomer data in the vehicle operation data according to a preset effective data standard; processing the effective monomer data according to a preset monomer consistency index processing method to obtain monomer consistency index data; and determining a total index deviation value of all battery monomers in the current vehicle according to the monomer consistency index data, and if the total index deviation value exceeds a preset deviation threshold, determining that the current vehicle has a consistency risk. According to the method, the consistency indexes of the battery monomers are comprehensively evaluated through the total index deviation value of the battery monomers, and the technical effect of improving the evaluation accuracy of the vehicle battery monomers is achieved.

    本申请公开了一种车辆电池单体一致性评估方法、装置、设备及存储介质,该方法包括:获取车辆运行数据,根据预设的有效数据标准筛选出所述车辆运行数据中的有效单体数据;根据预设的单体一致性指标处理方法对所述有效单体数据进行处理,得到单体一致性指标数据;根据所述单体一致性指标数据确定当前车辆中所有电池单体的总指标偏差值,若所述总指标偏差值超过预设的偏差阈值,则判定所述当前车辆存在一致性风险。本申请通过电池单体的总指标偏差值对电池单体各一致性指标进行综合评估,实现了提高车辆电池单体评估准确度的技术效果。
