一、電動車鋰電池充電大概需要多久

電動車鋰電池充(chong)電(dian)(dian)時(shi)(shi)間一(yi)般充(chong)多(duo)長為好，電(dian)(dian)動(dong)車鋰電(dian)(dian)池正確的(de)充(chong)電(dian)(dian)方法，需要按照標(biao)準的(de)時(shi)(shi)間和程序充(chong)電(dian)(dian)，即使是前三次也(ye)必須如此進行。充(chong)電(dian)(dian)器指示燈轉綠燈后，再充(chong)1-2小(xiao)時(shi)(shi)左(zuo)右(you)，即可停止充(chong)電(dian)(dian)工作。注意，不要進行超(chao)過(guo)12個小(xiao)時(shi)(shi)的(de)超(chao)長充(chong)電(dian)(dian)，一(yi)般充(chong)電(dian)(dian)時(shi)(shi)間控制在(zai)3-5小(xiao)時(shi)(shi)左(zuo)右(you)。

電(dian)動車鋰電(dian)池(chi)(chi)(chi)充電(dian)器都是三段(duan)(duan)式充電(dian)，即分為恒壓階(jie)(jie)(jie)段(duan)(duan)、恒流(liu)階(jie)(jie)(jie)段(duan)(duan)、涓(juan)流(liu)階(jie)(jie)(jie)段(duan)(duan)。前兩階(jie)(jie)(jie)段(duan)(duan)是充電(dian)的主要(yao)階(jie)(jie)(jie)段(duan)(duan)，完成后電(dian)池(chi)(chi)(chi)基本充滿，燈會變(bian)綠(lv)，進入涓(juan)流(liu)階(jie)(jie)(jie)段(duan)(duan)，保護電(dian)池(chi)(chi)(chi)。這(zhe)時(shi)(shi)不要(yao)拔下(xia)電(dian)源，繼(ji)續充電(dian)1-2小(xiao)時(shi)(shi)，可以有效增(zeng)加電(dian)池(chi)(chi)(chi)壽命，但變(bian)綠(lv)后不要(yao)超過8小(xiao)時(shi)(shi)。

一般電(dian)(dian)(dian)動車鋰電(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)，最(zui)好按規格說(shuo)明書上面的要(yao)求(qiu)來(lai)充(chong)(chong)，如果沒(mei)有了，要(yao)看鋰電(dian)(dian)(dian)池的容量和充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)(qi)的電(dian)(dian)(dian)流是(shi)多(duo)大，比(bi)如48V/20A的鋰電(dian)(dian)(dian)池，充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)(qi)是(shi)5A的，就要(yao)充(chong)(chong)4個小(xiao)時(shi)多(duo)一點，而10A的充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)(qi)充(chong)(chong)兩(liang)個小(xiao)時(shi)多(duo)一點，20A的充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)(qi)就充(chong)(chong)一個小(xiao)時(shi)。

一(yi)般給電(dian)(dian)(dian)動(dong)車的鋰電(dian)(dian)(dian)池充電(dian)(dian)(dian)的充電(dian)(dian)(dian)器，都(dou)是采用(yong)三段式充電(dian)(dian)(dian)模式，當100%用(yong)完電(dian)(dian)(dian)的情(qing)況下(xia)，一(yi)般充電(dian)(dian)(dian)時(shi)間(jian)會在(zai)8~10小時(shi)，不要超過12小時(shi)（對電(dian)(dian)(dian)池壽命會有影響）。也不建議(yi)每(mei)次使用(yong)都(dou)把電(dian)(dian)(dian)用(yong)完，一(yi)般建議(yi)用(yong)電(dian)(dian)(dian)量(liang)在(zai)70%左右就要進行(xing)充電(dian)(dian)(dian)了(le)，這時(shi)充電(dian)(dian)(dian)時(shi)間(jian)一(yi)般在(zai)6~8小時(shi)。

二、電動車鋰電池第一次充電要充多久

電(dian)(dian)(dian)動車使用(yong)(yong)的鋰(li)(li)電(dian)(dian)(dian)池(chi)主要分為三(san)(san)大(da)類(lei)，一(yi)(yi)種(zhong)是三(san)(san)元鋰(li)(li)，這也(ye)是目前使用(yong)(yong)最多的一(yi)(yi)種(zhong)鋰(li)(li)電(dian)(dian)(dian)池(chi)；二是磷酸(suan)鐵鋰(li)(li)；三(san)(san)是鈦(tai)酸(suan)鋰(li)(li)，鈦(tai)酸(suan)鋰(li)(li)使用(yong)(yong)的人很(hen)少。一(yi)(yi)般新買的電(dian)(dian)(dian)動車第(di)一(yi)(yi)次(ci)充(chong)電(dian)(dian)(dian)時(shi)間需要8至10小時(shi)左(zuo)(zuo)右，第(di)二次(ci)、第(di)三(san)(san)次(ci)充(chong)電(dian)(dian)(dian)時(shi)間需要6至8小時(shi)左(zuo)(zuo)右。

通(tong)常情況下電(dian)動車前(qian)3-5次電(dian)量(liang)(liang)過(guo)低時(shi)(shi)(shi)最好連續(xu)充(chong)(chong)(chong)電(dian)5小(xiao)時(shi)(shi)(shi)以上，但不要超過(guo)12小(xiao)時(shi)(shi)(shi)。當聽到(dao)電(dian)量(liang)(liang)過(guo)低提示(shi)時(shi)(shi)(shi)應(ying)盡(jin)量(liang)(liang)及(ji)時(shi)(shi)(shi)充(chong)(chong)(chong)電(dian)，如(ru)果新電(dian)池電(dian)量(liang)(liang)過(guo)低還持續(xu)使用的(de)話，對電(dian)池的(de)傷害比(bi)較嚴重(zhong)。日常使用電(dian)動車時(shi)(shi)(shi)建議充(chong)(chong)(chong)電(dian)方式：

1、每(mei)天的(de)用電(dian)量在10%時，可以一周充一次電(dian)；

2、每天的用電量在20%時(shi)，可以三天充(chong)一(yi)次電；

3、每(mei)天的(de)用電量在30%時(shi)，可以(yi)兩天充一次電；

4、每天的用(yong)電(dian)量(liang)在40%以上時(shi)，可以一(yi)天充一(yi)次(ci)(ci)電(dian)，每次(ci)(ci)在6小時(shi)左右。
