| 摘 要： | 大功率锂离子二次电池在贮存过程中通常出现失效数较少但性能退化较普遍的现象,而且测量所得的电池数据不确定和不完整。为评估电池贮存可靠度,该文提出了一种根据正常电池数据建立模糊隶属函数处理不完整数据的方法,通过该方法得到电池的贮存可靠度。通过多组数据计算,证明了该方法的有效性和实用性。

| Abstract: | The high power lithium batteries often display few failures but more energy loss in storage.Their energy pa-rameters and metrical data are indeterminate and incomplete.In order to evaluate the storage reliability of the battery,this paper presents a method,in which a fuzzy membership function is established to estimate the incomplete data of the battery based on normal data.The storage reliability of the battery can be obtained with this method.Comparison of several groups of battery data proved that the me... |
