摘要
近年来,随着动力电池技术的不断发展,越来越多的厂家青睐采用锂电池作为场(厂)内机动车动力源。然而,对场(厂)内机动车用锂电池的安全性能检测一直缺乏相关研究,特别是对故障电池的无损检测,鲜有开展。为此,本文采用高分辨率工业CT对场(厂)内机动车用故障锂电池进行研究,扫描内部结构,并结合充放电情况分析锂电池性能衰减与内部结构之间的关系,为场(厂)内机动车用锂电池无损检测提供解决方案。
In recent years,with the development of power battery technology,an increasing number of manufacturers have favored lithium batteries as forklift power sources.However,there has been a lack of relevant research on the safety performance of lithium batteries for forklifts,especially on the nondestructive inspection of faulty batteries,which is rarely performed.Therefore,this study adopted high-resolution industrial computed tomography(CT)to study faulty lithium batteries for forklifts,scanning the internal structure and analyzing the relationship between the performance attenuation of the lithium battery and the internal structure,thereby combining with the charging and discharging conditions,to provide a solution for the nondestructive inspection of lithium batteries in forklifts.
