大容量電池怎么組裝？
大容量電池怎么組裝，想知道嗎？那就要先學習了解電芯咯。因為大容量電池一般是由一個個鋰電池電芯組合組裝成的哦。要想知道大容量鋰電池怎么組裝，要先明白一個原理：電芯的串聯只提高電壓，不增容；電芯的并聯只增容，不提高電壓。
下面就來了解(jie)一下怎么(me)增大(da)鋰(li)電(dian)池容量的(de)方法吧：
例如(ru)想要一個(ge)6000mAH,16V的大容量(liang)電(dian)(dian)池。假如(ru)一個(ge)電(dian)(dian)芯(xin)的電(dian)(dian)壓是4V，容量(liang)是1200mAH，那(nei)么你(ni)就(jiu)要20個(ge)電(dian)(dian)芯(xin)。就(jiu)是要4個(ge)電(dian)(dian)芯(xin)組(zu)成(cheng)一個(ge)串(chuan)聯(lian)單元組(zu)，變(bian)成(cheng)一個(ge)16V的電(dian)(dian)池組(zu)，這(zhe)樣(yang)(yang)一個(ge)電(dian)(dian)池組(zu)的容量(liang)就(jiu)是1200mAH，然(ran)后將5個(ge)這(zhe)樣(yang)(yang)的單元電(dian)(dian)池組(zu)并聯(lian)起(qi)來，這(zhe)樣(yang)(yang)就(jiu)可以得到一個(ge)6000mAH，16V的大容量(liang)鋰(li)電(dian)(dian)池了。
12v大容(rong)(rong)量(liang)(liang)(liang)電(dian)(dian)(dian)(dian)池(chi)(chi)是(shi)指電(dian)(dian)(dian)(dian)池(chi)(chi)標(biao)稱電(dian)(dian)(dian)(dian)壓(ya)為(wei)(wei)12V，電(dian)(dian)(dian)(dian)池(chi)(chi)容(rong)(rong)量(liang)(liang)(liang)超過20000mAh的(de)電(dian)(dian)(dian)(dian)池(chi)(chi)。12鋰電(dian)(dian)(dian)(dian)池(chi)(chi)，是(shi)由3個(ge)3.7V的(de)鋰電(dian)(dian)(dian)(dian)池(chi)(chi)串(chuan)(chuan)聯(lian)(lian)組(zu)合，單個(ge)鋰電(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)滿(man)電(dian)(dian)(dian)(dian)后的(de)電(dian)(dian)(dian)(dian)壓(ya)為(wei)(wei)4.2V,一般情況(kuang)下也叫4V，串(chuan)(chuan)聯(lian)(lian)電(dian)(dian)(dian)(dian)池(chi)(chi)的(de) 電(dian)(dian)(dian)(dian)壓(ya)相加，既：4V/個(ge)電(dian)(dian)(dian)(dian)池(chi)(chi)*3個(ge)電(dian)(dian)(dian)(dian)也=12V，就是(shi)我們所說的(de)12V鋰電(dian)(dian)(dian)(dian)池(chi)(chi)。有些電(dian)(dian)(dian)(dian)池(chi)(chi)容(rong)(rong)量(liang)(liang)(liang)可達20AH，或50AH.電(dian)(dian)(dian)(dian)池(chi)(chi)并(bing)聯(lian)(lian)得越(yue)多，容(rong)(rong)量(liang)(liang)(liang)越(yue)大。根據物理(li)學(xue)公(gong)式：并(bing)聯(lian)(lian)電(dian)(dian)(dian)(dian)路中(zhong)：I總(zong)=I1+I2+I3。一般將容(rong)(rong)量(liang)(liang)(liang)超過20000mAh的(de)電(dian)(dian)(dian)(dian)池(chi)(chi)稱作大容(rong)(rong)量(liang)(liang)(liang)電(dian)(dian)(dian)(dian)池(chi)(chi)。
大容量電(dian)池組裝要注意的問題(ti)：
1、使用(yong)的電池(chi)電芯的電壓壓差(cha)不能太大(da)，最好是在20mV以內；
2、不建議使用(yong)不同廠(chang)家的(de)同類型電芯進行組裝(zhuang)，因為廠(chang)家會(hui)因為生產(chan)技(ji)術和電池(chi)材(cai)料(liao)配方(fang)的(de)差(cha)異，會(hui)導致(zhi)電芯之間的(de)工(gong)作效率不一致(zhi)，容易損(sun)害電池(chi)。
3、即使(shi)是使(shi)用同一(yi)個廠家的鋰電池電芯，也不能新舊混用；
4、即使是(shi)同一個廠家的電(dian)芯，建議使用(yong)同一批次生產的電(dian)芯；
