我們都知道電動車電池(chi)一般有兩種(zhong)(zhong)，一種(zhong)(zhong)是鉛酸電池(chi)，一種(zhong)(zhong)就是鋰電池(chi)，那么這兩種(zhong)(zhong)電池(chi)的可以混用嗎(ma)？如果用鉛酸電池的充電器給(gei)鋰電池充電，可以嗎(ma)？

首先(xian)我們一般不(bu)建(jian)議這樣(yang)用(yong)，有(you)點危險，雖然沒有(you)脈沖功能的(de)(de)(de)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器，理論是(shi)可(ke)以(yi)給(gei)鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)，但是(shi)依然可(ke)能會傷(shang)害鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，雖然鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)有(you)保護板(ban)(ban)，理論過充(chong)或者(zhe)過放時(shi)候能起到保護作(zuo)用(yong)，如果充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)經常(chang)觸(chu)發過充(chong)保護電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，那(nei)(nei)這個充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器的(de)(de)(de)輸出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)設置就(jiu)不(bu)正(zheng)確(que)。發生這樣(yang)的(de)(de)(de)現象后，那(nei)(nei)落后的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)永遠落后。有(you)保護板(ban)(ban)也盡量不(bu)要高。因為電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)盒里(li)使用(yong)，平時(shi)是(shi)看不(bu)到電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)一致(zhi)(zhi)性(xing)(xing)狀態的(de)(de)(de)，不(bu)知什么時(shi)候，萬(wan)一它的(de)(de)(de)一致(zhi)(zhi)性(xing)(xing)出問題了，這時(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)又高了幾V。那(nei)(nei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)就(jiu)要倒大霉了。

實際上(shang)，鉛酸(suan)(suan)電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)器為了克(ke)服鉛酸(suan)(suan)的(de)(de)大內阻,在恒(heng)(heng)流(liu)充(chong)電(dian)(dian)(dian)時把(ba)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓提高(gao)了5%左右(you),也就是(shi)說就是(shi)你選(xuan)用(yong)了一(yi)樣(yang)電(dian)(dian)(dian)壓充(chong)電(dian)(dian)(dian)器，給鋰電(dian)(dian)(dian)池供電(dian)(dian)(dian)時候(hou)，電(dian)(dian)(dian)壓會(hui)高(gao)出來一(yi)點的(de)(de)，因為鉛酸(suan)(suan)的(de)(de)內阻大，恒(heng)(heng)流(liu)充(chong)電(dian)(dian)(dian)為了達到效(xiao)率(lv)都是(shi)在恒(heng)(heng)流(liu)時把(ba)恒(heng)(heng)壓電(dian)(dian)(dian)壓升高(gao)，這(zhe)樣(yang)對鋰電(dian)(dian)(dian)池是(shi)很不利的(de)(de)。

當(dang)然，鉛(qian)酸電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)如果改(gai)進一下是可(ke)(ke)以(yi)(yi)給鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)，比如去(qu)掉(diao)低恒壓階段(duan)電(dian)(dian)(dian)(dian)(dian)(dian)路和脈沖電(dian)(dian)(dian)(dian)(dian)(dian)路，是可(ke)(ke)以(yi)(yi)用的(de)(de)。如果你如果觀察鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)曲線，可(ke)(ke)以(yi)(yi)發現在恒流階段(duan)充(chong)(chong)(chong)(chong)入約(yue)為96%的(de)(de)總容量(liang)；恒壓減流階段(duan)只充(chong)(chong)(chong)(chong)入4%的(de)(de)容量(liang)，如果轉燈就拔時，那鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)已經充(chong)(chong)(chong)(chong)入了(le)99.5%的(de)(de)容量(liang)了(le)。所以(yi)(yi)鉛(qian)酸充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器充(chong)(chong)(chong)(chong)鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)，也就是少(shao)了(le)最后的(de)(de)均(jun)衡和浮充(chong)(chong)(chong)(chong)那0.5%的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)而(er)已。將鉛(qian)充(chong)(chong)(chong)(chong)的(de)(de)高(gao)低恒壓都低調點，就都可(ke)(ke)以(yi)(yi)給鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)了(le)，只不(bu)過充(chong)(chong)(chong)(chong)不(bu)滿而(er)已。不(bu)過鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)又不(bu)會硫(liu)化，充(chong)(chong)(chong)(chong)不(bu)滿就充(chong)(chong)(chong)(chong)不(bu)滿吧(ba)，又不(bu)影(ying)響使用，壽命(ming)還會延長呀。
