聚合物鋰電池發生(sheng)(sheng)過充(chong)有很(hen)多(duo)(duo)原因(yin)，但是一般來說是不會(hui)發生(sheng)(sheng)過充(chong)的(de)，因(yin)為現在(zai)大多(duo)(duo)數電(dian)(dian)(dian)池都會(hui)配有電(dian)(dian)(dian)池保(bao)(bao)護板，比如手機、筆記本電(dian)(dian)(dian)腦等使(shi)用(yong)鋰聚(ju)合物電(dian)(dian)(dian)池時，為了防止過充(chong)電(dian)(dian)(dian)，經常(chang)是用(yong)電(dian)(dian)(dian)池保(bao)(bao)護板檢測電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)狀況，它的(de)功能是一旦發現異常(chang)，立即停止充(chong)電(dian)(dian)(dian)。因(yin)此，使(shi)用(yong)這(zhe)類機器充(chong)電(dian)(dian)(dian)的(de)鋰聚(ju)合物電(dian)(dian)(dian)池不會(hui)發生(sheng)(sheng)過充(chong)電(dian)(dian)(dian)情況。

但也有部分應用情況下，聚合物鋰電池是沒有配有電池保護板的，比如說車模電池、航模飛機(ji)電(dian)池(chi)、fpv無人機(ji)電(dian)池(chi)等(deng)這些，用的鋰(li)聚合物(wu)電(dian)池(chi)因(yin)為實際使用環境要(yao)求電(dian)池(chi)要(yao)更輕便化，因(yin)此，在(zai)電(dian)池(chi)上并(bing)未安裝具備(bei)上述功能的電(dian)池(chi)保護(hu)板，而是安裝在(zai)充(chong)電(dian)器上。

車模電池、航模飛機電池、fpv無人機電池等這些等用的(de)鋰(li)聚(ju)合物電(dian)(dian)(dian)池(chi)(chi)根(gen)據電(dian)(dian)(dian)池(chi)(chi)的(de)構成(cheng)有各(ge)種容(rong)(rong)量( 單位(wei)時間可使(shi)(shi)用的(de)電(dian)(dian)(dian)流量，單位(wei):mAh) 、充(chong)放電(dian)(dian)(dian)容(rong)(rong)許量( 單位(wei):CmA，C) 等不同產(chan)品，因此(ci)或者改變(bian)與之相(xiang)應的(de)充(chong)電(dian)(dian)(dian)器設定，或者使(shi)(shi)用各(ge)種電(dian)(dian)(dian)池(chi)(chi)的(de)專用充(chong)電(dian)(dian)(dian)器。否(fou)則(ze)，充(chong)電(dian)(dian)(dian)器附帶的(de)功(gong)能不發(fa)揮作用，有時難免發(fa)生過充(chong)電(dian)(dian)(dian)情況。

另外，注意充電時(shi)周邊(bian)沒有可燃物，放入(ru)不燃性專用袋(dai)中，同時(shi)整個充電過(guo)程中經常查看，預防電池是否發(fa)熱”膨脹等異(yi)常情(qing)況，如(ru)果忽略(lve)了這些使用上應注意的(de)問(wen)題進行充電的(de)話(hua)，就會過(guo)充電并著火。

( 1) 將鋰聚合物(wu)電(dian)池設定為鎳鉻電(dian)池( 鎳氫充(chong)(chong)(chong)電(dian)池) 充(chong)(chong)(chong)電(dian)時(shi)。當鎳鎘電(dian)池充(chong)(chong)(chong)電(dian)完(wan)成(cheng)時(shi)，會發生特有的電(dian)壓變化。電(dian)池檢測出這種變化，即停止充(chong)(chong)(chong)電(dian)。而鋰 聚合物(wu)電(dian)池沒有這方(fang)面功(gong)能，因此(ci)容(rong)易過(guo)充(chong)(chong)(chong)電(dian)。

(2) 當(dang)構成(cheng)鋰(li)聚(ju)合(he)物(wu)電(dian)(dian)池(chi)(chi)的各(ge)電(dian)(dian)池(chi)(chi)電(dian)(dian)壓(ya)(ya)失衡(heng)(heng)，并(bing)且充(chong)(chong)(chong)電(dian)(dian)時設定的不(bu)合(he)適時。鋰(li)聚(ju)合(he)物(wu)電(dian)(dian)池(chi)(chi)是將(jiang)幾個(ge)(ge)(ge)電(dian)(dian)池(chi)(chi)排列組合(he)在一起，因長年(nian)使(shi)用或使(shi)用條(tiao)件不(bu)同(tong)，各(ge)電(dian)(dian)池(chi)(chi)電(dian)(dian)壓(ya)(ya)平衡(heng)(heng)有(you)時產生(sheng)差異。為了改善這種狀(zhuang)態，準備能夠觀(guan)測(ce)各(ge)電(dian)(dian)池(chi)(chi)的充(chong)(chong)(chong)電(dian)(dian)狀(zhuang)況，并(bing)分別表示每(mei)個(ge)(ge)(ge)電(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)完成(cheng)的充(chong)(chong)(chong)電(dian)(dian)器，我們將(jiang)這種充(chong)(chong)(chong)電(dian)(dian)方法(fa)叫做平衡(heng)(heng)充(chong)(chong)(chong)電(dian)(dian)，當(dang)給各(ge)電(dian)(dian)池(chi)(chi)電(dian)(dian)壓(ya)(ya)產生(sheng)了差異的鋰(li)聚(ju)合(he)物(wu)電(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)時，如果未做平衡(heng)(heng)充(chong)(chong)(chong)電(dian)(dian)，排列的電(dian)(dian)池(chi)(chi)將(jiang)作為一個(ge)(ge)(ge)整體(ti)被觀(guan)測(ce)，即便整體(ti)電(dian)(dian)壓(ya)(ya)正常，其(qi)中(zhong)的單個(ge)(ge)(ge)電(dian)(dian)池(chi)(chi)也(ye)會出現過充(chong)(chong)(chong)電(dian)(dian)情況。

(3) 設定不(bu)對的情況下(xia)充(chong)電(dian)(dian)(dian)時。充(chong)電(dian)(dian)(dian)的鋰(li)聚合物電(dian)(dian)(dian)池數及充(chong)電(dian)(dian)(dian)方(fang)法”電(dian)(dian)(dian)壓(ya)”電(dian)(dian)(dian)流不(bu)正確時將出現過充(chong)電(dian)(dian)(dian)情況。
