基于特性曲线的锂离子电池分类新方法

A New Method to Classify Lithium-ion Battery based on Characteristic Curve

提出一种基于特性曲线的电池新分类方法，通过分析列放电特性曲线上的特征，解释各特征点的物理意义，并说明特征点的提取方法，同时提出了通过增长容量分析（ICA）法分析电池内部材料相变过程的思想，再采用FCM聚类算法对电池进行分类筛选。通过电池组循环寿命实验验证新方法的有效性。

A new battery characteristic curve based classification method, by analyzing the charge and discharge characteristics curve characteristics to explain the physical meaning of the feature points, and describes the feature point extraction method, and proposed increased capacity analysis through （ICA） analysis phase change material inside the battery idea, then using FCM clustering algorithm to classify the battery screening. Battery cycle life through experiments validate the new method.
