锂离子动力电池单体筛选方法研究
Study on screening method of lithium ion power battery
摘要
Abstract
An efficient and practical cell sieving method on the basis of feature points on the voltage-time curve was discussed.According to curvature,a feature extraction method was proposed to analyze the curve.Then the standard cell voltage-time curve equation was achieved by piecewise linear fitting.By calculating the distance between the non-standard cell feature points and the standard cell voltage-time curve,the similarity between cells was determined.To be exactly,similarity function was established,with certain threshold criteria applied as well,to sieving the voltage-time curves and the consistency of the results were analyzed.关键词
