基于BEYES估计的锂离子电池参数融合分类方法

Classification method of li ionic battery basede on data-fusion theory of beyes estimation

锂离子电池多以组合形式使用,因此使用时要将其分类,以便把性能一致的电池组合在一起。普遍使用的方法是if-then方法,且基于少数一两个参数。但实际情况是,反映锂离子电池性能的参数远不止一两个参数。文中就该问题提出一种新的分类方法。该方法利用电池在充放电时的记录数据,从中提取能反映电池性能的若干特征参数,将这些特征参数进行融合,然后把融合结果用于分类。

Li ionic battery often is used in packs.In order to pack the battery together with the same performance,we must classify them before using it.Now the common classification method adopts the if-then arithmetic,which is based on only few parameters.However,the parameters for-indicating performances of Li ionic battery are far more to from this.In this paper,a classification method of Li ionic battery based on data-fussion theory of Beyes esti-mation was introduced.The method abstracts certain character parameters,which indicates performance of the battery,according to the data recorded during charge and discharge pro-cess,and then divides them consequently.
