The invention relates to a novel sorting method for gradient utilization of power batteries. According to a traditional sorting method, parameter differences serve as sorting indexes, and the sorting effect is difficult to directly evaluate. Based on the parallel shunt characteristic of the module, the relation between the capacity utilization efficiency and the terminal load current is directly established by analyzing the dynamic change process of the current of each branch under the parallel condition, the maximum capacity utilization efficiency and the corresponding working state of the module can be observed, and then the sorting effect is evaluated. According to the sorting method, the battery cells with large parameter differences can be selected for grouping, the distinguishing accuracy is higher, different thoughts are provided for flexible grouping, and meanwhile reference is provided for evaluating the sorting effect through the Pack capacity utilization efficiency. 本发明为一种用于动力电池梯次利用的新型分选方法。传统分选方法以参
