The invention discloses a charging data consistency determination method and device. The method comprises the following steps: acquiring charging data of a battery pack in the electric vehicle in a sampling period; obtaining a plurality of charging data variations of each single battery; obtaining a first charging data mean value of each single battery; determining a charging data total capacity, and determining a second charging data mean value of the battery pack; determining a statistical index of a first error of the charging data in each single battery; determining a statistical index of a second error of the charging data between the single batteries; determining a charging data statistical value of each single battery, and determining a charging data critical value; and comparing the charging data statistical value with the charging data critical value to determine a charging data consistency evaluation index of the single battery. According to the method and the device, the technical problem that the potential safety hazard of the battery cannot be checked in time due to the fact that the consistency of the charging data cannot be accurately determined based on the charging data of the battery pack in the sampling period in the prior art is solved.

    本申请公开了一种充电数据一致性确定方法及装置。该方法包括:获取电动汽车中的电池组在采样周期内的充电数据;得到每个单体电池的多个充电数据变化量;得到每个单体电池的第一充电数据均值;确定充电数据总容量,确定电池组的第二充电数据均值;确定每个单体电池内部的充电数据的第一误差的统计学指标;确定各个单体电池之间的充电数据的第二误差的统计学指标;确定每个单体电池的充电数据统计值,确定充电数据临界值;比较充电数据统计值与充电数据临界值,以确定单体电池的充电数据一致性评价指标。本申请解决了由于相关技术无法基于电池组在采样周期内的充电数据,精准确定充电数据的一致性,造成的无法及时排查电池的安全隐患的技术问题。
