鋰(li)電池(chi)組都會(hui)有保護板(ban)，用(yong)(yong)來保護電池(chi)組的。小編整理搜(sou)集了一些(xie)關于鋰(li)電池(chi)保護板(ban)的作用(yong)(yong)及原理介(jie)紹資(zi)料，希望可以幫到(dao)您參考。

一、鋰電池保護板的構成

保護板通(tong)(tong)常包括(kuo)控制(zhi)(zhi)IC、MOS開關(guan)及輔助器(qi)件NTC、ID、存儲器(qi)等。其(qi)中控制(zhi)(zhi)IC，在(zai)一(yi)切正常的情況下控制(zhi)(zhi)MOS開關(guan)導通(tong)(tong)，使電(dian)芯與外電(dian)路溝通(tong)(tong)，而當電(dian)芯電(dian)壓或回路電(dian)流超過規定值時，它立(li)刻控制(zhi)(zhi)MOS開關(guan)關(guan)斷，保護電(dian)芯的安全。

鋰(li)電(dian)(dian)(dian)(dian)池保(bao)護(hu)(hu)板(ban)是系(xi)列鋰(li)電(dian)(dian)(dian)(dian)池組的(de)充(chong)放電(dian)(dian)(dian)(dian)保(bao)護(hu)(hu)，當完全充(chong)電(dian)(dian)(dian)(dian)時，可(ke)以保(bao)證單(dan)(dan)個電(dian)(dian)(dian)(dian)池之(zhi)間(jian)的(de)電(dian)(dian)(dian)(dian)壓(ya)差小于設定值，實現(xian)電(dian)(dian)(dian)(dian)池組各(ge)電(dian)(dian)(dian)(dian)池的(de)均(jun)衡，從(cong)而有效提高(gao)串聯充(chong)電(dian)(dian)(dian)(dian)模式(shi)下的(de)充(chong)電(dian)(dian)(dian)(dian)效果。同(tong)時檢測電(dian)(dian)(dian)(dian)池組各(ge)單(dan)(dan)體(ti)的(de)過壓(ya)、欠壓(ya)、過流(liu)、短(duan)路和過熱，保(bao)護(hu)(hu)和延(yan)長電(dian)(dian)(dian)(dian)池壽命，保(bao)護(hu)(hu)防止每一(yi)個單(dan)(dan)體(ti)電(dian)(dian)(dian)(dian)池在放電(dian)(dian)(dian)(dian)過程中因過放電(dian)(dian)(dian)(dian)而損(sun)壞。

?二、鋰電池保護板的作用

成品鋰(li)(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)主(zhu)要由(you)鋰(li)(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)和(he)保(bao)護(hu)(hu)板(ban)兩大部(bu)分組(zu)成。鋰(li)(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)芯主(zhu)要由(you)正(zheng)極(ji)(ji)板(ban)、隔(ge)板(ban)、負極(ji)(ji)板(ban)和(he)電(dian)(dian)(dian)解質組(zu)成;將所述正(zheng)極(ji)(ji)板(ban)、隔(ge)膜(mo)和(he)負極(ji)(ji)板(ban)繞繞或疊(die)層、封裝(zhuang)，并注入電(dian)(dian)(dian)解液，封裝(zhuang)后形(xing)成電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)芯。鋰(li)(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)保(bao)護(hu)(hu)板(ban)的(de)(de)作用很多人(ren)并不知道，鋰(li)(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)保(bao)護(hu)(hu)板(ban)，顧名思義就是保(bao)護(hu)(hu)鋰(li)(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)。鋰(li)(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)保(bao)護(hu)(hu)板(ban)的(de)(de)作用是保(bao)護(hu)(hu)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)但不充電(dian)(dian)(dian)，但不流動，并對輸出短路進行保(bao)護(hu)(hu)。對于這個(ge)問題，認為鋰(li)(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)不需要保(bao)護(hu)(hu)板(ban)的(de)(de)人(ren)會(hui)覺得鋰(li)(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)不會(hui)連接到保(bao)護(hu)(hu)板(ban)上，保(bao)護(hu)(hu)板(ban)會(hui)將長期未使用的(de)(de)鋰(li)(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)的(de)(de)點放電(dian)(dian)(dian)。
