一、当聚合物软包锂(li)电池无法(fa)充电时是什么原因？
1）检(jian)查电(dian)池是否为零电(dian)压、高内阻电(dian)池；
2）检(jian)查(cha)保护(hu)电(dian)路(lu)的连接是否(fou)异常；
3）检(jian)查电(dian)池在充(chong)电(dian)状态下是否有异常，如(ru)无充(chong)电(dian)电(dian)压(ya)/电(dian)流输出；
4）环境温(wen)度是否过高导(dao)致充电效率低(di)（佳温(wen)度不(bu)应超过40℃）。
处理方法：
1）了(le)解电池的具体使用情(qing)况；
2）将同型号电(dian)池和(he)万用(yong)表串(chuan)联(lian)到电(dian)路中充(chong)电(dian)，根据(ju)充(chong)电(dian)电(dian)流值判断充(chong)电(dian)装置(zhi)是(shi)否正常。
3）重复单体电池零电压步骤的分析处(chu)理；
4）选择稳定(ding)性较好(hao)的充电设备。
二、聚合(he)物软包(bao)锂电池无法放电是什(shen)么(me)原因(yin)？
1）检查电池/电池组(zu)是否零(ling)电压、高内(nei)阻；
2）检查(cha)电(dian)子(zi)元件和保护电(dian)路是否损坏；
3) 检查设(she)备放(fang)电回路(lu)是否正常。
处理方法：
1）使(shi)用充满电的同(tong)类型电池连接设备，查看设备是(shi)否正常工(gong)作(zuo)；
2）用(yong)万用(yong)表检查(cha)电(dian)池(chi)内(nei)部的(de)电(dian)子(zi)元件和保护电(dian)路是否(fou)正常；
3）对单体电池(chi)的零电压(ya)步骤重复(fu)分(fen)析(xi)处理；
4）电(dian)器(qi)放电(dian)电(dian)路(lu)出现异常(chang)，建议(yi)及时维修更换电(dian)器(qi)。
