鋰電池保護板是(shi)對(dui)串聯鋰電池組的(de)充放電保護。

在充(chong)(chong)滿電(dian)(dian)時(shi)(shi)能保(bao)證各單體(ti)電(dian)(dian)池(chi)(chi)(chi)之間的電(dian)(dian)壓(ya)差異小于設定值(一(yi)般±20mV)，實現(xian)電(dian)(dian)池(chi)(chi)(chi)組各單體(ti)電(dian)(dian)池(chi)(chi)(chi)的均充(chong)(chong)，有效地改善了串聯(lian)充(chong)(chong)電(dian)(dian)方式(shi)下的充(chong)(chong)電(dian)(dian)效果;同(tong)時(shi)(shi)檢測電(dian)(dian)池(chi)(chi)(chi)組中各個單體(ti)電(dian)(dian)池(chi)(chi)(chi)的過(guo)(guo)壓(ya)、欠壓(ya)、過(guo)(guo)流、短路、過(guo)(guo)溫(wen)狀(zhuang)態(tai)，保(bao)護(hu)并延長電(dian)(dian)池(chi)(chi)(chi)使用壽命;欠壓(ya)保(bao)護(hu)使每一(yi)單節電(dian)(dian)池(chi)(chi)(chi)在放電(dian)(dian)使用時(shi)(shi)避免電(dian)(dian)池(chi)(chi)(chi)因過(guo)(guo)放電(dian)(dian)而損壞。

成(cheng)品鋰(li)電(dian)池(chi)組成(cheng)主要有兩大(da)部分，鋰(li)電(dian)池(chi)芯(xin)和保護板(ban)，鋰(li)電(dian)池(chi)芯(xin)主要由正(zheng)極板(ban)、隔(ge)膜(mo)、負極板(ban)、電(dian)解液組成(cheng);正(zheng)極板(ban)、隔(ge)膜(mo)、負極板(ban)纏繞(rao)或層疊(die)，包(bao)裝(zhuang)(zhuang)，灌注電(dian)解液，封裝(zhuang)(zhuang)后即制(zhi)成(cheng)電(dian)芯(xin)，鋰(li)電(dian)池(chi)保護板(ban)的(de)作用(yong)很多(duo)人都不知道，鋰(li)電(dian)池(chi)保護板(ban)，顧名思義就是(shi)(shi)保護鋰(li)電(dian)池(chi)用(yong)的(de)，鋰(li)電(dian)池(chi)保護板(ban)的(de)作用(yong)是(shi)(shi)保護電(dian)池(chi)不過(guo)放、不過(guo)充(chong)、不過(guo)流，還有就是(shi)(shi)輸(shu)出短路保護:
