The invention provides a consistency estimation method for a power battery, the power battery is composed of a plurality of battery cells and is used for providing energy for a vehicle, and the estimation method comprises the following steps: detecting the working voltage of each battery cell in the plurality of battery cells in real time during the operation of the vehicle to obtain a first voltage data set of each battery cell; performing first filtering processing on the first voltage data set to retain voltage data corresponding to the working current smaller than a first threshold value so as to obtain a filtered second voltage data set of each battery cell; calculating an energy fraction of each battery cell based on the second voltage data set; and calculating a first consistency score of the power battery based on the calculated energy score of each battery cell. And providing a visual representation of the energy fraction for each cell as a function of a particular variable.
本公开提供一种用于动力电池的一致性的估计方法,该动力电池由多个电芯构成并且用于为车辆提供能量,该估计方法包括:在车辆的运行期间实时地检测多个电芯中的每个电芯的工作电压,以获得每个电芯的第一电压数据集;对第一电压数据集进行第一过滤处理,以保留与小于第一阈值的工作电流相对应的电压数据,从而获得每个电芯的过滤后的第二电压数据集;基于第二电压数据集,计算每个电芯的能量分数;以及基于所计算的每个电芯的能量分数,计算动力电池的第一一致性分数。并且提供每个电芯的能量分数作为特定变量的函数的可视化表示。
