18650鋰電池組包(bao)含大概(gai)三個(ge)部分：18650鋰(li)電(dian)(dian)池(chi)(chi)、電(dian)(dian)池(chi)(chi)保護(hu)板、外(wai)包(bao)裝。把多(duo)個(ge)18650鋰(li)電(dian)(dian)池(chi)(chi)串(chuan)聯(lian)或者并聯(lian)起(qi)來得到所需要的電(dian)(dian)池(chi)(chi)組工(gong)作電(dian)(dian)壓和放電(dian)(dian)電(dian)(dian)流。 那么18650鋰(li)電(dian)(dian)池(chi)(chi)串(chuan)聯(lian)與并聯(lian)有什么不同？下面跟著(zhu)小編一(yi)起(qi)來看(kan)看(kan)18650鋰(li)電(dian)(dian)池(chi)(chi)串(chuan)聯(lian)與并聯(lian)吧！

一、18650鋰電池串聯
把多個(ge)(ge)18650鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)串(chuan)聯(lian)(lian)(lian)(lian)起來(lai)，可以等到得到所(suo)組(zu)合電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)個(ge)(ge)數相加的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)值，但是(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流不(bu)(bu)變，鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)串(chuan)聯(lian)(lian)(lian)(lian)的(de)(de)原理就是(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)增加，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流不(bu)(bu)變。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)串(chuan)聯(lian)(lian)(lian)(lian)帶來(lai)的(de)(de)高電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)也(ye)存在著(zhu)一些嚴重的(de)(de)問題，如(ru)果18650鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)組(zu)串(chuan)聯(lian)(lian)(lian)(lian)起來(lai)工(gong)作時(shi)，當其中有(you)一節(jie)18650鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)失效(xiao)了(le)就會(hui)影(ying)響(xiang)整(zheng)個(ge)(ge)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)組(zu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)下降，使用的(de)(de)時(shi)間急劇縮短，而且(qie)壞(huai)的(de)(de)那一節(jie)18650鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)有(you)很大(da)的(de)(de)內(nei)阻，如(ru)果此時(shi)還(huan)強行工(gong)作的(de)(de)話就會(hui)導致整(zheng)個(ge)(ge)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)組(zu)的(de)(de)輸(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)下降很大(da)。串(chuan)聯(lian)(lian)(lian)(lian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)對于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)基本參數要(yao)求不(bu)(bu)是(shi)(shi)(shi)太(tai)高，但是(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)一致性還(huan)是(shi)(shi)(shi)越高越好，主要(yao)原因是(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)使用有(you)一個(ge)(ge)衰(shuai)減過(guo)程，不(bu)(bu)一致的(de)(de)參數，會(hui)導致電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)某節(jie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)衰(shuai)減速(su)度加快(kuai)，串(chuan)聯(lian)(lian)(lian)(lian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路壞(huai)了(le)一節(jie)，全盤都報廢了(le)，不(bu)(bu)過(guo)好在這(zhe)種效(xiao)果不(bu)(bu)是(shi)(shi)(shi)很強烈，影(ying)響(xiang)不(bu)(bu)大(da)，只要(yao)不(bu)(bu)用不(bu)(bu)同類型，不(bu)(bu)同容量的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)串(chuan)聯(lian)(lian)(lian)(lian)，基本無大(da)礙。

二、18650鋰電池并聯
把多節(jie)18650鋰電(dian)池并聯(lian)組合起(qi)來(lai)，就可以(yi)得到更大的(de)電(dian)量，說的(de)專業一點的(de)是(shi)“容(rong)量”。鋰電(dian)池并聯(lian)是(shi)電(dian)壓不(bu)變，容(rong)量增加。有多少節(jie)鋰電(dian)池并聯(lian)，總容(rong)量就是(shi)所有單節(jie)鋰電(dian)池容(rong)量相加起(qi)來(lai)的(de)總值。

三、18650鋰電串并聯相結合

串并聯組合方法就是先把幾組串聯好的鋰電池組，再進(jin)行(xing)(xing)并聯(lian)，這樣不(bu)僅(jin)僅(jin)提高了(le)電(dian)(dian)(dian)池(chi)組(zu)的輸出電(dian)(dian)(dian)壓，同時也大大提高了(le)18650鋰電(dian)(dian)(dian)池(chi)組(zu)的容量，就(jiu)像我們經常用到的交通(tong)工具電(dian)(dian)(dian)動自行(xing)(xing)車鋰電(dian)(dian)(dian)池(chi)一樣。就(jiu)是用這鐘(zhong)組(zu)合方式來形成 36V/20Ah的高電(dian)(dian)(dian)壓高容量的。單節18650鋰電(dian)(dian)(dian)池(chi)一般都是3.7V ，要(yao)做到36V高電(dian)(dian)(dian)壓那就(jiu)要(yao)10組(zu)串聯(lian)電(dian)(dian)(dian)池(chi)來組(zu)成。

好了，上面幾點就是我(wo)個人平(ping)時積累的(de)一些關于(yu)18650鋰電池組(zu)并聯與串(chuan)聯的(de)區別小知識，很高興(xing)能(neng)分享給大家看到。
