Battery grouping with time series clustering based on features

Battery grouping is important to the performance of the whole battery pack. In this paper, we use time series clustering algorithm for battery grouping. The proposed method uses the battery discharge curve to complete the grouping. First, we extract several kinds of characteristics of the discharge sequence. The similarities between batteries are then computed according to these features. Finally, a fast search and find of the density peak is utilized to cluster these features to accomplish the battery grouping. Experimental results show that the proposed battery grouping method is effective.
