    In order to improve the consistency for lithium-ion power battery of electric vehicle, to raise the available power and the utilization ratio of capacity for the battery pack, this paper put forward a battery sorting method based on the inconsistency mechanism analysis of battery. Firstly, the traditional sorting method, the main factor sorting method and the total factor sorting method for battery were completed respectively, and the comparative results show that the total factor sorting method is optimal. Secondly, the dynamic characteristics sorting was carried by fuzzy c-means clustering algorithm based on the total factor sorting results. Finally, the sorting effect was verified through experiments and the result shows that this sorting method can improve the inconsistency for battery pack effectively, and has a certain practical significance.
