聚合物鋰電池要做相應的維護保養才能讓其電池性能發揮得更加徹底，同時也可以起到一定的延長使用壽命的目的，可以節約一定的費用支出，那么聚合物鋰電池維護保養方法具體怎么做呢？

1.充電操(cao)作(zuo)時(shi)要(yao)有專(zhuan)業人(ren)員進行看護，充電過程中確保(bao)插頭與插座接觸良好，確保(bao)充電設備工作(zuo)正常，確保(bao)電池組(zu)各(ge)連接點接觸良好。如(ru)果(guo)出現異常，需要(yao)修復(fu)后才能充電；

2.充電和(he)放電前檢查BMS的顯示器上顯示的電池電壓、溫度、壓差(cha)等狀態(tai)，確保所有值都處于正常范圍內；

3.若(ruo)電池組(zu)上蓋與極柱上存在大量灰塵、金(jin)屬屑或(huo)其他雜物，及時使(shi)(shi)用(yong)(yong)壓縮空氣(qi)進(jin)行清理(li)，避免使(shi)(shi)用(yong)(yong)水(shui)或(huo)水(shui)浸濕的物體進(jin)行清潔；

4.充(chong)電(dian)(dian)和(he)放電(dian)(dian)時盡量避(bi)免有水(shui)或其他導電(dian)(dian)物體濺到電(dian)(dian)池(chi)上蓋(gai)與極柱處(chu)，例(li)如暴露在大(da)雨中使(shi)用；

5.根據電(dian)(dian)池或電(dian)(dian)池組(zu)實(shi)際使用(yong)狀態估計電(dian)(dian)池的(de)充電(dian)(dian)時間和(he)放電(dian)(dian)時間，在充電(dian)(dian)末期和(he)放電(dian)(dian)末期注意(yi)觀察(cha)電(dian)(dian)池或電(dian)(dian)池組(zu)是否存在異常，如電(dian)(dian)池的(de)電(dian)(dian)壓(ya)差問題。

8.2定期保養

1.檢查BMS顯示器上(shang)的電(dian)壓(ya)數據與實際電(dian)池電(dian)壓(ya)值，以確保BMS的電(dian)壓(ya)采(cai)集(ji)的準確性，若不一(yi)致則要進行校對(dui)，采(cai)集(ji)的電(dian)壓(ya)與實際電(dian)池電(dian)壓(ya)誤差不超過5mV（1次/月）；

2.檢查BMS的(de)溫度(du)(du)采(cai)集數(shu)據(ju)與實際溫度(du)(du)值，采(cai)集數(shu)據(ju)與實際溫度(du)(du)值的(de)數(shu)據(ju)誤差不(bu)允許(xu)超過3℃，確(que)保電池不(bu)會在溫度(du)(du)過高或溫度(du)(du)過低的(de)時候被充(chong)電或者放電，（1次/月）；

3.檢查BIS的電流采集數據(ju)與實際(ji)電流值，誤差不允許超(chao)過1%，確保電池不會被(bei)過電流充電或者過電流放電（1次/月）；

4.檢查導電帶、電壓采集端子等(deng)節點是否存在松動、脫落、生銹或者變形等(deng)情況，確保電池組使用的串并聯線束(shu)牢固(gu)可(ke)靠(kao)（1次/月）；

5.檢查(cha)電池外殼是否存在裂縫、變形、極(ji)柱(zhu)松動(dong)、鼓脹等異常情況（1次/月）；

6.檢查(cha)充電(dian)設(she)備的(de)可靠(kao)性，確保充電(dian)設(she)備完全按照(zhao)BMS發出的(de)調(diao)壓調(diao)流(liu)信號(hao)執行充電(dian)動作，確保電(dian)池不(bu)會被過充電(dian)（1次/月）；

7.檢查放電保護(hu)設(she)備，例(li)如(ru)快(kuai)速(su)熔斷器、直流接觸器、繼(ji)電器、空氣開關(guan)等，確保若出現短路、過流等危險狀況時電池組(zu)能(neng)被快(kuai)速(su)切斷主回路（1次/月）；

8.測試電(dian)(dian)(dian)機控(kong)制器(qi)、車載空調控(kong)制器(qi)等高壓用電(dian)(dian)(dian)設備的通(tong)訊及執(zhi)行功(gong)能，確(que)保當BMS發出切斷信(xin)號時(shi)，所有高壓用電(dian)(dian)(dian)設備能及時(shi)停止用電(dian)(dian)(dian)，確(que)保電(dian)(dian)(dian)池不被過放(fang)電(dian)(dian)(dian)（1次/月）；

9.檢查電(dian)(dian)池組與車(che)體(ti)的絕緣電(dian)(dian)阻狀態，確保(bao)阻值符合中國國家標準(zhun)（≥500Ω/V），以保(bao)證電(dian)(dian)池不存(cun)在漏(lou)電(dian)(dian)現象（1次/月）；

10.若出現電池組帶(dai)電量不一致(zhi)的情(qing)況(kuang)時，解決的方(fang)法(fa)如下：

A、使用帶有均(jun)衡(heng)功能(neng)且均(jun)衡(heng)功能(neng)效果(guo)非常好的管(guan)理(li)系統(tong)，最好是具(ju)有均(jun)衡(heng)充電功能(neng)的管(guan)理(li)系統(tong)。
