The invention provides a vehicle battery pack abnormity identification method and a vehicle service platform, and the method comprises the steps: obtaining the charging data of each battery cell in a battery pack under a charging condition, and the charging data comprises the battery cell voltage value and the charge state value of each battery cell; distributing the battery cell voltage value of each battery cell to a corresponding charge state interval according to the charge state; for each charge state interval, calculating a consistency coefficient of the charge state interval according to the voltage values of all the battery cells in the charge state interval; and for each state-of-charge interval, according to a comparison result of the consistency coefficient of the state-of-charge interval and a preset consistency threshold value corresponding to the state-of-charge interval, identifying that the consistency of the battery cells of the battery pack is abnormal. According to the invention, the method achieves the precise recognition of the consistency abnormality of the cells in the battery pack, and reduces the risk probability of the battery pack.

    本申请提供了一种车辆电池包的异常识别方法及车辆服务平台,其中,该方法包括:获取电池包中的每个电芯在充电工况下的充电数据,所述充电数据包括每个电芯的电芯电压值和荷电状态值;将所述每个电芯的电芯电压值按照所述荷电状态分配到对应的荷电状态区间内;针对每个荷电状态区间,根据该荷电状态区间内的所有电芯电压值,计算该荷电状态区间的一致性系数;针对每个荷电状态区间,根据该荷电状态区间的一致性系数与该荷电状态区间对应的预设一致性阈值的比较结果,识别所述电池包的电芯一致性异常。通过本申请,实现了对电池包中电芯一致性异常的精准识别,降低了电池包发生风险的概率。
