18650鋰電池組包(bao)含大概(gai)三個(ge)部(bu)分：18650鋰(li)電(dian)(dian)池、電(dian)(dian)池保護板、外包(bao)裝。把多個(ge)18650鋰(li)電(dian)(dian)池串聯(lian)或(huo)者并聯(lian)起(qi)(qi)來得(de)到(dao)所(suo)需要的電(dian)(dian)池組工作電(dian)(dian)壓和放電(dian)(dian)電(dian)(dian)流。 那么18650鋰(li)電(dian)(dian)池串聯(lian)與并聯(lian)有什么不同？下面跟著小編一起(qi)(qi)來看看18650鋰(li)電(dian)(dian)池串聯(lian)與并聯(lian)吧！

一、18650鋰電池串聯
把多個18650鋰電(dian)(dian)(dian)池(chi)(chi)(chi)串聯(lian)(lian)起(qi)來，可以等到(dao)得到(dao)所組(zu)合電(dian)(dian)(dian)池(chi)(chi)(chi)個數(shu)相加的(de)(de)(de)(de)電(dian)(dian)(dian)壓(ya)(ya)值，但(dan)是(shi)電(dian)(dian)(dian)流(liu)不(bu)(bu)(bu)(bu)變(bian)，鋰電(dian)(dian)(dian)池(chi)(chi)(chi)串聯(lian)(lian)的(de)(de)(de)(de)原理(li)就是(shi)電(dian)(dian)(dian)壓(ya)(ya)增(zeng)加，電(dian)(dian)(dian)流(liu)不(bu)(bu)(bu)(bu)變(bian)。電(dian)(dian)(dian)池(chi)(chi)(chi)串聯(lian)(lian)帶來的(de)(de)(de)(de)高電(dian)(dian)(dian)壓(ya)(ya)也(ye)存(cun)在(zai)著一(yi)(yi)些嚴重的(de)(de)(de)(de)問題，如果18650鋰電(dian)(dian)(dian)池(chi)(chi)(chi)組(zu)串聯(lian)(lian)起(qi)來工(gong)作(zuo)時(shi)，當其中有一(yi)(yi)節(jie)(jie)18650鋰電(dian)(dian)(dian)池(chi)(chi)(chi)失效(xiao)(xiao)了就會影(ying)響整個電(dian)(dian)(dian)池(chi)(chi)(chi)組(zu)的(de)(de)(de)(de)電(dian)(dian)(dian)壓(ya)(ya)下(xia)降(jiang)，使用的(de)(de)(de)(de)時(shi)間急劇縮(suo)短，而且壞(huai)的(de)(de)(de)(de)那一(yi)(yi)節(jie)(jie)18650鋰電(dian)(dian)(dian)池(chi)(chi)(chi)有很(hen)大的(de)(de)(de)(de)內阻，如果此時(shi)還(huan)強行工(gong)作(zuo)的(de)(de)(de)(de)話就會導致整個電(dian)(dian)(dian)池(chi)(chi)(chi)組(zu)的(de)(de)(de)(de)輸(shu)出電(dian)(dian)(dian)壓(ya)(ya)下(xia)降(jiang)很(hen)大。串聯(lian)(lian)電(dian)(dian)(dian)池(chi)(chi)(chi)對于電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)(de)基本(ben)參(can)數(shu)要(yao)求(qiu)不(bu)(bu)(bu)(bu)是(shi)太高，但(dan)是(shi)電(dian)(dian)(dian)池(chi)(chi)(chi)一(yi)(yi)致性還(huan)是(shi)越(yue)(yue)高越(yue)(yue)好，主要(yao)原因是(shi)電(dian)(dian)(dian)池(chi)(chi)(chi)使用有一(yi)(yi)個衰(shuai)(shuai)減過(guo)程(cheng)，不(bu)(bu)(bu)(bu)一(yi)(yi)致的(de)(de)(de)(de)參(can)數(shu)，會導致電(dian)(dian)(dian)池(chi)(chi)(chi)某節(jie)(jie)電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)(de)衰(shuai)(shuai)減速(su)度加快，串聯(lian)(lian)電(dian)(dian)(dian)路壞(huai)了一(yi)(yi)節(jie)(jie)，全(quan)盤都報廢(fei)了，不(bu)(bu)(bu)(bu)過(guo)好在(zai)這種效(xiao)(xiao)果不(bu)(bu)(bu)(bu)是(shi)很(hen)強烈，影(ying)響不(bu)(bu)(bu)(bu)大，只要(yao)不(bu)(bu)(bu)(bu)用不(bu)(bu)(bu)(bu)同(tong)類型(xing)，不(bu)(bu)(bu)(bu)同(tong)容(rong)量的(de)(de)(de)(de)電(dian)(dian)(dian)池(chi)(chi)(chi)串聯(lian)(lian)，基本(ben)無大礙。

二、18650鋰電池并聯
把多節18650鋰(li)電(dian)池(chi)并聯(lian)組合(he)起來，就可以得(de)到更大的電(dian)量，說的專業一點的是“容量”。鋰(li)電(dian)池(chi)并聯(lian)是電(dian)壓不變，容量增加。有(you)(you)多少(shao)節鋰(li)電(dian)池(chi)并聯(lian)，總(zong)容量就是所有(you)(you)單節鋰(li)電(dian)池(chi)容量相(xiang)加起來的總(zong)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，再進行并聯，這樣(yang)不僅僅提(ti)高(gao)了電(dian)(dian)池組的輸出電(dian)(dian)壓(ya)，同時也大大提(ti)高(gao)了18650鋰(li)電(dian)(dian)池組的容(rong)量，就像我們經常(chang)用到的交(jiao)通工具(ju)電(dian)(dian)動自行車鋰(li)電(dian)(dian)池一(yi)樣(yang)。就是用這鐘組合方(fang)式(shi)來形成 36V/20Ah的高(gao)電(dian)(dian)壓(ya)高(gao)容(rong)量的。單(dan)節18650鋰(li)電(dian)(dian)池一(yi)般(ban)都是3.7V ，要做(zuo)到36V高(gao)電(dian)(dian)壓(ya)那就要10組串聯電(dian)(dian)池來組成。

好(hao)了(le)，上面幾點(dian)就(jiu)是我(wo)個人平(ping)時積累的一(yi)些關于18650鋰(li)電池(chi)組并(bing)聯與串聯的區別小知識，很(hen)高興能分享給大家看到。
