現在電動車使用鋰電池和鉛酸蓄電池的都(dou)有，很多朋友在(zai)更換或增加電動車電池(chi)容量的時候，會有鋰(li)電池(chi)與(yu)鉛(qian)(qian)酸電池(chi)可以并(bing)聯(lian)使用嗎，這(zhe)樣(yang)的疑問。小(xiao)編告訴(su)你們(men)，鋰(li)電池(chi)與(yu)鉛(qian)(qian)酸電池(chi)不(bu)管串聯(lian)還是并(bing)聯(lian)都(dou)不(bu)行一起使用；即使是同是鋰(li)電池(chi)或是鉛(qian)(qian)酸電池(chi)，容量不(bu)一樣(yang)的電池(chi)是不(bu)能串并(bing)聯(lian)使用的，具體的原因如下：

鋰電(dian)池和鉛酸(suan)電(dian)池能并聯使用嗎？

小編肯定的(de)回答你們，鐵鋰(li)電(dian)池和鉛(qian)酸電(dian)池不能并聯使用，原因如下：

1、電池放電平(ping)臺不(bu)一(yi)樣

鋰電池(chi)(chi)單支(zhi)的(de)是(shi)(shi)(shi)3.7V，鉛(qian)酸電池(chi)(chi)單節是(shi)(shi)(shi)2*2＝4V，（鉛(qian)酸單格是(shi)(shi)(shi)2V,一(yi)個電池(chi)(chi)可以做(zuo)2-6格，甚(shen)至是(shi)(shi)(shi)8格的(de)，也就是(shi)(shi)(shi)4-16V），,如果并(bing)在(zai)一(yi)起會(hui)出現一(yi)種電用完了，另(ling)一(yi)種還有很多(duo)電，這樣就會(hui)很容(rong)易造成先放完電的(de)電池(chi)(chi)過放，損(sun)害電池(chi)(chi)使用壽命。

2、電(dian)池(chi)充電(dian)方式和電(dian)流(liu)大小(xiao)不一(yi)樣(yang)

鉛(qian)酸電(dian)(dian)(dian)池(chi)(chi)是(shi)均充(chong)方式，就(jiu)(jiu)是(shi)恒流恒壓的(de)充(chong)電(dian)(dian)(dian)，而(er)鋰電(dian)(dian)(dian)池(chi)(chi)是(shi)先恒流再恒壓充(chong)，如果(guo)一開始就(jiu)(jiu)恒壓會將激活鋰電(dian)(dian)(dian)池(chi)(chi)管理板保護功能導致不(bu)充(chong)電(dian)(dian)(dian)。鋰電(dian)(dian)(dian)池(chi)(chi)在充(chong)電(dian)(dian)(dian)的(de)時(shi)候能接受的(de)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流要(yao)比鉛(qian)酸蓄電(dian)(dian)(dian)池(chi)(chi)的(de)要(yao)大，一起充(chong)電(dian)(dian)(dian)的(de)時(shi)候，鉛(qian)酸電(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流過大，損壞(huai)電(dian)(dian)(dian)池(chi)(chi)壽(shou)命，電(dian)(dian)(dian)池(chi)(chi)用不(bu)了50次(ci)。

3、電(dian)(dian)池(chi)放電(dian)(dian)電(dian)(dian)流大小不一樣(yang)

電(dian)池在進(jin)行放(fang)電(dian)的(de)時候，鋰電(dian)池放(fang)電(dian)電(dian)流會比(bi)鉛酸電(dian)池要(yao)大，這樣一(yi)來，鉛酸電(dian)池會因為放(fang)電(dian)電(dian)流過大導致(zhi)電(dian)池發(fa)熱嚴重，影響(xiang)電(dian)池使用壽命(ming)。

同等電(dian)壓(ya)的鐵鋰電(dian)池和鉛酸電(dian)池并聯使用會怎樣？

鐵鋰電池和鉛酸電池不(bu)管串聯和并聯都不(bu)行(xing)。

串聯：

1、放電(dian)：容量不同的電(dian)池，放電(dian)時，總會有一個先(xian)放完電(dian)，而另一個仍(reng)然電(dian)壓較高；

2、電(dian)池沒電(dian)：壽命縮短80%，甚(shen)至損壞；

3、充(chong)(chong)(chong)電(dian)(dian)：容量不同的(de)電(dian)(dian)池，充(chong)(chong)(chong)電(dian)(dian)時，總會有一個(ge)先充(chong)(chong)(chong)滿電(dian)(dian)，而另一個(ge)仍然電(dian)(dian)壓較低，這(zhe)時，充(chong)(chong)(chong)電(dian)(dian)器會繼續保持充(chong)(chong)(chong)電(dian)(dian)，已經充(chong)(chong)(chong)滿的(de)電(dian)(dian)瓶(ping)存在過充(chong)(chong)(chong)電(dian)(dian)的(de)風(feng)險；

4、電(dian)(dian)池過充電(dian)(dian)：將打破化學平衡，并伴隨(sui)水的電(dian)(dian)解，同樣會損壞電(dian)(dian)池；

并聯：

電(dian)(dian)(dian)池(chi)(chi)之間充(chong)電(dian)(dian)(dian)，當某(mou)一電(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)壓下降時，電(dian)(dian)(dian)壓高(gao)的(de)電(dian)(dian)(dian)瓶就會(hui)向它(ta)充(chong)電(dian)(dian)(dian)，且電(dian)(dian)(dian)流(liu)大小不受控制，如果此(ci)電(dian)(dian)(dian)流(liu)與(yu)來(lai)自發電(dian)(dian)(dian)機的(de)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)疊加，哪怕是瞬(shun)間，對電(dian)(dian)(dian)池(chi)(chi)的(de)損(sun)害也很(hen)大，某(mou)只電(dian)(dian)(dian)池(chi)(chi)損(sun)壞后，好(hao)電(dian)(dian)(dian)池(chi)(chi)會(hui)一直對其(qi)充(chong)電(dian)(dian)(dian)，直到自身的(de)電(dian)(dian)(dian)量耗盡。

綜上所述(shu)，容量不(bu)(bu)一(yi)樣(yang)的鋰電池和鉛酸(suan)電池是不(bu)(bu)能串聯(lian)使(shi)用的，除非你在充(chong)、放電過程中，人(ren)為干預，隨時測量電池電壓，并(bing)能及時處置。電池并(bing)聯(lian)使(shi)用有苛(ke)刻(ke)的條件，要求(qiu)同(tong)廠(chang)、同(tong)型號規格、同(tong)批(pi)次(ci)、同(tong)時接入(ru)電路，使(shi)用環境相同(tong)，否則(ze)，不(bu)(bu)建(jian)議使(shi)用。

鋰電池的串(chuan)聯和并聯注意事項有哪些？

不要(yao)將不同品(pin)牌鋰(li)電池(chi)，不同容量或新舊鋰(li)電池(chi)混在一(yi)起使用，選擇(ze)性能一(yi)致的電池(chi)。

當電(dian)(dian)池的(de)電(dian)(dian)量不足時，更(geng)換所有的(de)電(dian)(dian)池。鋰電(dian)(dian)池串聯使(shi)用時，要用同(tong)一(yi)種類型的(de)電(dian)(dian)池。

一(yi)般鋰(li)電(dian)池(chi)(chi)串并(bing)聯使(shi)用需(xu)要進(jin)行(xing)鋰(li)電(dian)池(chi)(chi)芯(xin)(xin)配(pei)對(dui)，配(pei)對(dui)的標準：鋰(li)電(dian)池(chi)(chi)芯(xin)(xin)電(dian)壓差(cha)≤10mV，鋰(li)電(dian)池(chi)(chi)芯(xin)(xin)內阻差(cha)≤5mΩ，鋰(li)電(dian)池(chi)(chi)芯(xin)(xin)容量差(cha)≤20mA。

總結：雖然說鋰電(dian)池(chi)(chi)與鉛酸電(dian)池(chi)(chi)是(shi)不能并聯在一起(qi)使(shi)(shi)用(yong)的，但是(shi)可以(yi)進(jin)行替換(huan)使(shi)(shi)用(yong)，就(jiu)是(shi)將(jiang)用(yong)電(dian)器(qi)用(yong)的電(dian)池(chi)(chi)全部換(huan)成鋰電(dian)池(chi)(chi)或是(shi)鉛酸電(dian)池(chi)(chi)的形式。
