一、電動車鋰電池充電大概需要多久

電動車鋰電池充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)時(shi)(shi)間(jian)一般充(chong)(chong)(chong)(chong)多長(chang)為(wei)好，電(dian)(dian)(dian)動車(che)鋰(li)電(dian)(dian)(dian)池正確的充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)方法，需(xu)要(yao)按(an)照標準的時(shi)(shi)間(jian)和程(cheng)序充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)，即(ji)使(shi)是前三次(ci)也(ye)必須如此進行。充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器指(zhi)示燈轉綠(lv)燈后，再充(chong)(chong)(chong)(chong)1-2小(xiao)時(shi)(shi)左右(you)，即(ji)可(ke)停止充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)工作(zuo)。注(zhu)意，不要(yao)進行超過12個(ge)小(xiao)時(shi)(shi)的超長(chang)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)，一般充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)時(shi)(shi)間(jian)控制在3-5小(xiao)時(shi)(shi)左右(you)。

電(dian)(dian)動車(che)鋰電(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)器都是(shi)三段(duan)式充(chong)電(dian)(dian)，即分為恒(heng)壓階(jie)(jie)段(duan)、恒(heng)流階(jie)(jie)段(duan)、涓流階(jie)(jie)段(duan)。前兩階(jie)(jie)段(duan)是(shi)充(chong)電(dian)(dian)的主要(yao)階(jie)(jie)段(duan)，完成后電(dian)(dian)池(chi)(chi)基本充(chong)滿，燈會(hui)變綠(lv)，進入涓流階(jie)(jie)段(duan)，保護電(dian)(dian)池(chi)(chi)。這時(shi)不(bu)要(yao)拔下電(dian)(dian)源，繼續充(chong)電(dian)(dian)1-2小時(shi)，可以有(you)效增加電(dian)(dian)池(chi)(chi)壽命(ming)，但變綠(lv)后不(bu)要(yao)超過8小時(shi)。

一(yi)(yi)般電動(dong)車鋰電池充(chong)(chong)電，最好按規格(ge)說明書上(shang)面的(de)要求來充(chong)(chong)，如果沒有了，要看鋰電池的(de)容量和充(chong)(chong)電器(qi)的(de)電流是多大，比如48V/20A的(de)鋰電池，充(chong)(chong)電器(qi)是5A的(de)，就(jiu)要充(chong)(chong)4個(ge)小時多一(yi)(yi)點(dian)，而10A的(de)充(chong)(chong)電器(qi)充(chong)(chong)兩個(ge)小時多一(yi)(yi)點(dian)，20A的(de)充(chong)(chong)電器(qi)就(jiu)充(chong)(chong)一(yi)(yi)個(ge)小時。

一般(ban)給電(dian)(dian)(dian)(dian)動車的(de)(de)鋰(li)電(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)的(de)(de)充(chong)電(dian)(dian)(dian)(dian)器，都是采用三段(duan)式(shi)充(chong)電(dian)(dian)(dian)(dian)模式(shi)，當100%用完電(dian)(dian)(dian)(dian)的(de)(de)情(qing)況下，一般(ban)充(chong)電(dian)(dian)(dian)(dian)時(shi)間會在8~10小時(shi)，不要超過12小時(shi)（對電(dian)(dian)(dian)(dian)池壽命會有影響(xiang)）。也不建議(yi)每次使(shi)用都把電(dian)(dian)(dian)(dian)用完，一般(ban)建議(yi)用電(dian)(dian)(dian)(dian)量在70%左右就要進行充(chong)電(dian)(dian)(dian)(dian)了，這時(shi)充(chong)電(dian)(dian)(dian)(dian)時(shi)間一般(ban)在6~8小時(shi)。

二、電動車鋰電池第一次充電要充多久

電(dian)(dian)動車(che)使(shi)用的(de)鋰(li)(li)電(dian)(dian)池(chi)主(zhu)要(yao)分(fen)為三(san)(san)大類，一(yi)種(zhong)是三(san)(san)元鋰(li)(li)，這也是目前使(shi)用最多的(de)一(yi)種(zhong)鋰(li)(li)電(dian)(dian)池(chi)；二是磷酸鐵鋰(li)(li)；三(san)(san)是鈦酸鋰(li)(li)，鈦酸鋰(li)(li)使(shi)用的(de)人(ren)很少。一(yi)般(ban)新買的(de)電(dian)(dian)動車(che)第(di)一(yi)次充(chong)電(dian)(dian)時間(jian)需要(yao)8至10小時左(zuo)右(you)，第(di)二次、第(di)三(san)(san)次充(chong)電(dian)(dian)時間(jian)需要(yao)6至8小時左(zuo)右(you)。

通常(chang)情況下電(dian)(dian)動車(che)前3-5次(ci)電(dian)(dian)量過(guo)(guo)低時(shi)(shi)最好(hao)連續充電(dian)(dian)5小(xiao)時(shi)(shi)以上，但不要超過(guo)(guo)12小(xiao)時(shi)(shi)。當聽到電(dian)(dian)量過(guo)(guo)低提示時(shi)(shi)應盡量及時(shi)(shi)充電(dian)(dian)，如(ru)果新電(dian)(dian)池電(dian)(dian)量過(guo)(guo)低還持續使(shi)用(yong)的(de)話，對電(dian)(dian)池的(de)傷害比較嚴重(zhong)。日常(chang)使(shi)用(yong)電(dian)(dian)動車(che)時(shi)(shi)建議充電(dian)(dian)方式：

1、每天的用電量在10%時，可以(yi)一周充一次電；

2、每天的用電(dian)量在20%時，可(ke)以三天充一次電(dian)；

3、每天(tian)的(de)用電(dian)量(liang)在30%時，可以(yi)兩天(tian)充一(yi)次電(dian)；

4、每天(tian)的(de)用電量(liang)在40%以上時(shi)(shi)，可以一(yi)天(tian)充一(yi)次電，每次在6小(xiao)時(shi)(shi)左右。
