鋰電池組在市場以及各個領域的應用已經屢見不鮮，給我們的生活，工業等等帶來了很多的益處，當然，鋰電池組在沖放電的過程中最重要的一個環節就是均衡環節，因為你需要保證鋰電池組的輸出以及輸出合理到每一節電池，目前鋰電池組均衡方法最常見的兩種方式，分別是耗能式均衡和轉能式均衡。

鋰電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)組(zu)(zu)耗(hao)能(neng)(neng)(neng)式(shi)均(jun)衡(heng)顧名(ming)思(si)義就(jiu)(jiu)是(shi)把鋰電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)組(zu)(zu)中(zhong)某節電(dian)(dian)(dian)(dian)壓高的(de)(de)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)用電(dian)(dian)(dian)(dian)阻(zu)把多余電(dian)(dian)(dian)(dian)量(liang)耗(hao)盡(jin)。這(zhe)種(zhong)方(fang)式(shi)的(de)(de)均(jun)衡(heng)的(de)(de)成(cheng)本較(jiao)(jiao)(jiao)(jiao)低(di)，設計也是(shi)相(xiang)對(dui)簡單，在鋰電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)組(zu)(zu)中(zhong)單節鋰電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)之(zhi)間(jian)的(de)(de)電(dian)(dian)(dian)(dian)壓不能(neng)(neng)(neng)達到一(yi)(yi)(yi)致時能(neng)(neng)(neng)夠(gou)起到一(yi)(yi)(yi)定的(de)(de)作用，但是(shi)相(xiang)對(dui)的(de)(de)，這(zhe)種(zhong)方(fang)式(shi)的(de)(de)均(jun)衡(heng)也較(jiao)(jiao)(jiao)(jiao)為容(rong)(rong)易出現故障(zhang)，而且(qie)均(jun)衡(heng)時鋰電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)所發出的(de)(de)溫度(du)較(jiao)(jiao)(jiao)(jiao)高。而且(qie)有(you)一(yi)(yi)(yi)點(dian)，因為鋰電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)組(zu)(zu)中(zhong)各個單節電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)電(dian)(dian)(dian)(dian)容(rong)(rong)都(dou)不盡(jin)相(xiang)同，所以每(mei)次充電(dian)(dian)(dian)(dian)，容(rong)(rong)量(liang)較(jiao)(jiao)(jiao)(jiao)小(xiao)的(de)(de)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)(dian)(dian)量(liang)會很快的(de)(de)達到飽和(he)，由于容(rong)(rong)量(liang)較(jiao)(jiao)(jiao)(jiao)大(da)的(de)(de)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)還在充電(dian)(dian)(dian)(dian)中(zhong)，容(rong)(rong)量(liang)較(jiao)(jiao)(jiao)(jiao)小(xiao)的(de)(de)鋰電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)就(jiu)(jiu)會均(jun)衡(heng)，以類似于放電(dian)(dian)(dian)(dian)額形式(shi)去(qu)耗(hao)除電(dian)(dian)(dian)(dian)量(liang)一(yi)(yi)(yi)直循環直到大(da)容(rong)(rong)量(liang)的(de)(de)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)(dian)(dian)量(liang)飽和(he)為止，所以大(da)家可以想(xiang)象(xiang)時間(jian)久了，容(rong)(rong)量(liang)較(jiao)(jiao)(jiao)(jiao)小(xiao)的(de)(de)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)整體性(xing)能(neng)(neng)(neng)就(jiu)(jiu)會大(da)大(da)額下(xia)降，這(zhe)個就(jiu)(jiu)跟(gen)我們手機電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)長時間(jian)用性(xing)能(neng)(neng)(neng)下(xia)降是(shi)一(yi)(yi)(yi)個道理。所以鋰電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)組(zu)(zu)耗(hao)能(neng)(neng)(neng)式(shi)均(jun)衡(heng)存在著很大(da)的(de)(de)弊端。

鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)組能(neng)量(liang)(liang)(liang)(liang)轉移(yi)(yi)式(shi)(shi)均(jun)(jun)衡(heng)(heng)也很好理解，就(jiu)是讓電(dian)(dian)(dian)池(chi)(chi)(chi)組中能(neng)量(liang)(liang)(liang)(liang)較高(gao)額鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)轉移(yi)(yi)到(dao)(dao)能(neng)量(liang)(liang)(liang)(liang)較低的(de)(de)(de)(de)鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)上，這種方(fang)式(shi)(shi)的(de)(de)(de)(de)均(jun)(jun)衡(heng)(heng)乍一聽(ting)確(que)實很實用(yong)，但(dan)是在(zai)實際情況下(xia)，目(mu)前(qian)的(de)(de)(de)(de)能(neng)量(liang)(liang)(liang)(liang)轉移(yi)(yi)式(shi)(shi)均(jun)(jun)衡(heng)(heng)并(bing)不(bu)是很完善，因(yin)(yin)為這種方(fang)式(shi)(shi)的(de)(de)(de)(de)均(jun)(jun)衡(heng)(heng)并(bing)不(bu)能(neng)通過檢測單節電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)(de)電(dian)(dian)(dian)壓來進行能(neng)量(liang)(liang)(liang)(liang)轉移(yi)(yi)的(de)(de)(de)(de)，而(er)是通過電(dian)(dian)(dian)池(chi)(chi)(chi)容(rong)量(liang)(liang)(liang)(liang)來進行能(neng)量(liang)(liang)(liang)(liang)轉移(yi)(yi)的(de)(de)(de)(de)，當高(gao)能(neng)量(liang)(liang)(liang)(liang)的(de)(de)(de)(de)電(dian)(dian)(dian)池(chi)(chi)(chi)向(xiang)低能(neng)量(liang)(liang)(liang)(liang)的(de)(de)(de)(de)電(dian)(dian)(dian)池(chi)(chi)(chi)轉移(yi)(yi)能(neng)量(liang)(liang)(liang)(liang)的(de)(de)(de)(de)時候，因(yin)(yin)為均(jun)(jun)衡(heng)(heng)電(dian)(dian)(dian)流以及充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流時固定的(de)(de)(de)(de)，不(bu)可(ke)控的(de)(de)(de)(de)，所(suo)以在(zai)轉移(yi)(yi)的(de)(de)(de)(de)時候，低容(rong)量(liang)(liang)(liang)(liang)的(de)(de)(de)(de)電(dian)(dian)(dian)池(chi)(chi)(chi)可(ke)能(neng)會(hui)達到(dao)(dao)過充(chong)值(zhi)，鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)保護板就(jiu)會(hui)工作從而(er)停(ting)止充(chong)電(dian)(dian)(dian)，那么整個(ge)循(xun)環就(jiu)會(hui)因(yin)(yin)此(ci)終止。
