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)時(shi)(shi)(shi)間(jian)(jian)一(yi)般充(chong)多(duo)長(chang)為好(hao)，電(dian)動(dong)車鋰電(dian)池正確(que)的充(chong)電(dian)方法，需要(yao)按照標(biao)準(zhun)的時(shi)(shi)(shi)間(jian)(jian)和程序充(chong)電(dian)，即(ji)使是前(qian)三(san)次(ci)也必(bi)須如此進行。充(chong)電(dian)器指示(shi)燈轉綠燈后，再充(chong)1-2小(xiao)時(shi)(shi)(shi)左右，即(ji)可停止(zhi)充(chong)電(dian)工作。注意，不要(yao)進行超(chao)過(guo)12個小(xiao)時(shi)(shi)(shi)的超(chao)長(chang)充(chong)電(dian)，一(yi)般充(chong)電(dian)時(shi)(shi)(shi)間(jian)(jian)控制在3-5小(xiao)時(shi)(shi)(shi)左右。

電(dian)(dian)(dian)動車(che)鋰(li)電(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)器都是三(san)段式(shi)充電(dian)(dian)(dian)，即分為(wei)恒(heng)壓階段、恒(heng)流階段、涓流階段。前兩階段是充電(dian)(dian)(dian)的(de)主要(yao)階段，完成后(hou)電(dian)(dian)(dian)池(chi)基本充滿，燈(deng)會變(bian)綠，進入(ru)涓流階段，保護電(dian)(dian)(dian)池(chi)。這時(shi)不要(yao)拔下電(dian)(dian)(dian)源，繼續充電(dian)(dian)(dian)1-2小(xiao)時(shi)，可以(yi)有效增加電(dian)(dian)(dian)池(chi)壽(shou)命(ming)，但(dan)變(bian)綠后(hou)不要(yao)超(chao)過8小(xiao)時(shi)。

一(yi)(yi)般電(dian)(dian)動車鋰(li)(li)(li)電(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)，最好按規格說明書上面的(de)(de)要(yao)求來充(chong)(chong)，如(ru)(ru)果沒有(you)了，要(yao)看鋰(li)(li)(li)電(dian)(dian)池(chi)(chi)的(de)(de)容量和充(chong)(chong)電(dian)(dian)器的(de)(de)電(dian)(dian)流是多大(da)，比如(ru)(ru)48V/20A的(de)(de)鋰(li)(li)(li)電(dian)(dian)池(chi)(chi)，充(chong)(chong)電(dian)(dian)器是5A的(de)(de)，就(jiu)要(yao)充(chong)(chong)4個小(xiao)(xiao)時多一(yi)(yi)點，而10A的(de)(de)充(chong)(chong)電(dian)(dian)器充(chong)(chong)兩(liang)個小(xiao)(xiao)時多一(yi)(yi)點，20A的(de)(de)充(chong)(chong)電(dian)(dian)器就(jiu)充(chong)(chong)一(yi)(yi)個小(xiao)(xiao)時。

一(yi)(yi)般給電(dian)(dian)動車的(de)鋰電(dian)(dian)池充(chong)(chong)電(dian)(dian)的(de)充(chong)(chong)電(dian)(dian)器，都是(shi)采用三(san)段式充(chong)(chong)電(dian)(dian)模式，當100%用完(wan)電(dian)(dian)的(de)情(qing)況下，一(yi)(yi)般充(chong)(chong)電(dian)(dian)時(shi)(shi)間(jian)會在(zai)8~10小(xiao)時(shi)(shi)，不(bu)要超(chao)過12小(xiao)時(shi)(shi)（對電(dian)(dian)池壽命會有影響(xiang)）。也不(bu)建(jian)議每次使用都把(ba)電(dian)(dian)用完(wan)，一(yi)(yi)般建(jian)議用電(dian)(dian)量在(zai)70%左右就要進行充(chong)(chong)電(dian)(dian)了，這時(shi)(shi)充(chong)(chong)電(dian)(dian)時(shi)(shi)間(jian)一(yi)(yi)般在(zai)6~8小(xiao)時(shi)(shi)。

二、電動車鋰電池第一次充電要充多久

電動車使用(yong)(yong)的(de)鋰(li)電池(chi)主要分為三(san)(san)大類，一種是(shi)(shi)三(san)(san)元鋰(li)，這也是(shi)(shi)目前使用(yong)(yong)最多的(de)一種鋰(li)電池(chi)；二是(shi)(shi)磷酸鐵(tie)鋰(li)；三(san)(san)是(shi)(shi)鈦(tai)酸鋰(li)，鈦(tai)酸鋰(li)使用(yong)(yong)的(de)人很少。一般新(xin)買的(de)電動車第(di)一次充電時(shi)(shi)間需(xu)要8至(zhi)10小(xiao)(xiao)時(shi)(shi)左(zuo)(zuo)右，第(di)二次、第(di)三(san)(san)次充電時(shi)(shi)間需(xu)要6至(zhi)8小(xiao)(xiao)時(shi)(shi)左(zuo)(zuo)右。

通常情況下(xia)電(dian)動車前3-5次電(dian)量過低時(shi)(shi)(shi)最(zui)好連續充電(dian)5小時(shi)(shi)(shi)以上，但(dan)不要超過12小時(shi)(shi)(shi)。當聽到(dao)電(dian)量過低提示(shi)時(shi)(shi)(shi)應盡量及時(shi)(shi)(shi)充電(dian)，如果新(xin)電(dian)池電(dian)量過低還持(chi)續使(shi)(shi)用(yong)的(de)話(hua)，對電(dian)池的(de)傷害比較嚴重。日常使(shi)(shi)用(yong)電(dian)動車時(shi)(shi)(shi)建議充電(dian)方式：

1、每天的用電量在10%時(shi)，可以一周充一次電；

2、每天(tian)的用電(dian)量在20%時，可以(yi)三天(tian)充一次電(dian)；

3、每天的用電(dian)量在30%時，可以兩天充一次電(dian)；

4、每天的用電(dian)量在(zai)40%以上時，可以一天充一次(ci)電(dian)，每次(ci)在(zai)6小時左(zuo)右。
