如何平衡聚合物软包锂电池

2022-04-19

聚合物软包锂电池

在有(you)多个电(dian)(dian)(dian)池单元的(de)(de)聚(ju)合(he)(he)物(wu)软包(bao)锂(li)电(dian)(dian)(dian)池中(zhong)(zhong)(zhong),平(ping)衡(heng)仅仅是使电(dian)(dian)(dian)池组中(zhong)(zhong)(zhong)电(dian)(dian)(dian)池单元的(de)(de)电(dian)(dian)(dian)压均衡(heng)的(de)(de)过程(cheng)。我们为什么(me)(me)(me)要这么(me)(me)(me)做?如(ru)(ru)果(guo)电(dian)(dian)(dian)池不平(ping)衡(heng)会(hui)发生什么(me)(me)(me)?例如(ru)(ru),在充电(dian)(dian)(dian)的(de)(de)2S电(dian)(dian)(dian)池中(zhong)(zhong)(zhong),如(ru)(ru)果(guo)一(yi)个电(dian)(dian)(dian)池的(de)(de)电(dian)(dian)(dian)压为4.1V,另一(yi)个为4.2V,则表示不平(ping)衡(heng)。简而言之,聚(ju)合(he)(he)物(wu)软包(bao)锂(li)电(dian)(dian)(dian)池中(zhong)(zhong)(zhong)的(de)(de)不平(ping)衡(heng)电(dian)(dian)(dian)池会(hui)显著降低其(qi)预期寿命。平(ping)衡(heng)很简单,为什么(me)(me)(me)要扔掉(diao)聚(ju)合(he)(he)物(wu)软包(bao)锂(li)电(dian)(dian)(dian)池呢?

实际的(de)聚合(he)物(wu)软(ruan)包锂电(dian)(dian)池(chi)(chi)平(ping)(ping)衡,这(zhei)比你(ni)想象(xiang)的(de)要容易,需要一个能(neng)够平(ping)(ping)衡充(chong)电(dian)(dian)的(de)充(chong)电(dian)(dian)器(qi),主要是聚合(he)物(wu)软(ruan)包锂电(dian)(dian)池(chi)(chi)充(chong)电(dian)(dian)器(qi)。这(zhei)很简单,将(jiang)平(ping)(ping)衡连接器(qi)(从较小的(de)电(dian)(dian)线)插入平(ping)(ping)衡充(chong)电(dian)(dian)器(qi),设(she)置适当的(de)电(dian)(dian)压,容量和平(ping)(ping)衡充(chong)电(dian)(dian)器(qi)上的(de)设(she)置。那么如何(he)检查聚合(he)物(wu)软(ruan)包锂电(dian)(dian)池(chi)(chi)是否(fou)平(ping)(ping)衡呢?

购买一(yi)个万用表(biao)(biao)。大多数的(de)万用表(biao)(biao)不只是检(jian)查电(dian)(dian)池(chi)电(dian)(dian)压(ya)。其中一(yi)些可以充(chong)当(dang)充(chong)放电(dian)(dian)器,检(jian)查电(dian)(dian)池(chi)的(de)容(rong)量,也可以检(jian)查电(dian)(dian)池(chi)的(de)内(nei)阻。为了确(que)保充(chong)分利用电(dian)(dian)池(chi),必(bi)须(xu)定期检(jian)查电(dian)(dian)池(chi)电(dian)(dian)压(ya),并确(que)保它是平(ping)衡(heng)的(de)。使用电(dian)(dian)池(chi)仪表(biao)(biao)通常就像把平(ping)衡(heng)插(cha)头插(cha)到仪表(biao)(biao)上(shang)一(yi)样(yang)简单。检(jian)查电(dian)(dian)池(chi)的(de)各种电(dian)(dian)压(ya),看看是否平(ping)衡(heng)。
