一、電動車鋰電池充電大概需要多久

電動車鋰電池充(chong)(chong)電(dian)(dian)時(shi)(shi)間(jian)一般(ban)充(chong)(chong)多長(chang)為好，電(dian)(dian)動車鋰電(dian)(dian)池(chi)正(zheng)確(que)的充(chong)(chong)電(dian)(dian)方法，需要按照(zhao)標(biao)準(zhun)的時(shi)(shi)間(jian)和程序充(chong)(chong)電(dian)(dian)，即使是(shi)前三次也(ye)必須如此進(jin)行。充(chong)(chong)電(dian)(dian)器(qi)指示燈轉(zhuan)綠燈后，再充(chong)(chong)1-2小時(shi)(shi)左右，即可停止充(chong)(chong)電(dian)(dian)工(gong)作。注意，不要進(jin)行超(chao)過12個小時(shi)(shi)的超(chao)長(chang)充(chong)(chong)電(dian)(dian)，一般(ban)充(chong)(chong)電(dian)(dian)時(shi)(shi)間(jian)控制(zhi)在3-5小時(shi)(shi)左右。

電(dian)(dian)動車鋰(li)電(dian)(dian)池(chi)充電(dian)(dian)器都(dou)是三段(duan)式充電(dian)(dian)，即分(fen)為恒壓階(jie)段(duan)、恒流階(jie)段(duan)、涓流階(jie)段(duan)。前兩階(jie)段(duan)是充電(dian)(dian)的主要階(jie)段(duan)，完成(cheng)后電(dian)(dian)池(chi)基本充滿，燈會變(bian)綠(lv)，進入涓流階(jie)段(duan)，保護電(dian)(dian)池(chi)。這(zhe)時(shi)不(bu)要拔(ba)下電(dian)(dian)源，繼續充電(dian)(dian)1-2小(xiao)時(shi)，可以有(you)效增加電(dian)(dian)池(chi)壽命，但變(bian)綠(lv)后不(bu)要超過(guo)8小(xiao)時(shi)。

一般電(dian)(dian)動車鋰電(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)，最好按(an)規格說(shuo)明(ming)書上面(mian)的(de)要(yao)求來(lai)充(chong)(chong)，如(ru)果沒有(you)了(le)，要(yao)看鋰電(dian)(dian)池(chi)的(de)容量和充(chong)(chong)電(dian)(dian)器(qi)的(de)電(dian)(dian)流(liu)是(shi)多(duo)大，比如(ru)48V/20A的(de)鋰電(dian)(dian)池(chi)，充(chong)(chong)電(dian)(dian)器(qi)是(shi)5A的(de)，就(jiu)要(yao)充(chong)(chong)4個(ge)(ge)小(xiao)時(shi)(shi)多(duo)一點(dian)，而10A的(de)充(chong)(chong)電(dian)(dian)器(qi)充(chong)(chong)兩(liang)個(ge)(ge)小(xiao)時(shi)(shi)多(duo)一點(dian)，20A的(de)充(chong)(chong)電(dian)(dian)器(qi)就(jiu)充(chong)(chong)一個(ge)(ge)小(xiao)時(shi)(shi)。

一(yi)(yi)般(ban)(ban)給電(dian)(dian)動車的鋰電(dian)(dian)池(chi)充電(dian)(dian)的充電(dian)(dian)器，都(dou)(dou)是采用(yong)三段式(shi)充電(dian)(dian)模式(shi)，當(dang)100%用(yong)完電(dian)(dian)的情況下，一(yi)(yi)般(ban)(ban)充電(dian)(dian)時間會在8~10小時，不要超過(guo)12小時（對電(dian)(dian)池(chi)壽命會有影響）。也不建議每次使用(yong)都(dou)(dou)把電(dian)(dian)用(yong)完，一(yi)(yi)般(ban)(ban)建議用(yong)電(dian)(dian)量在70%左右(you)就要進行充電(dian)(dian)了，這時充電(dian)(dian)時間一(yi)(yi)般(ban)(ban)在6~8小時。

二、電動車鋰電池第一次充電要充多久

電(dian)動車使(shi)用(yong)的鋰(li)(li)電(dian)池(chi)主要分為三(san)(san)大類，一種是(shi)三(san)(san)元鋰(li)(li)，這(zhe)也(ye)是(shi)目前使(shi)用(yong)最多的一種鋰(li)(li)電(dian)池(chi)；二(er)是(shi)磷酸鐵鋰(li)(li)；三(san)(san)是(shi)鈦(tai)(tai)酸鋰(li)(li)，鈦(tai)(tai)酸鋰(li)(li)使(shi)用(yong)的人很少(shao)。一般新(xin)買的電(dian)動車第(di)(di)一次(ci)充電(dian)時(shi)間需要8至10小(xiao)時(shi)左(zuo)右，第(di)(di)二(er)次(ci)、第(di)(di)三(san)(san)次(ci)充電(dian)時(shi)間需要6至8小(xiao)時(shi)左(zuo)右。

通常情況下電(dian)(dian)(dian)動(dong)車前3-5次電(dian)(dian)(dian)量過(guo)低時(shi)(shi)最(zui)好連續充(chong)電(dian)(dian)(dian)5小時(shi)(shi)以上，但不(bu)要超過(guo)12小時(shi)(shi)。當聽到電(dian)(dian)(dian)量過(guo)低提(ti)示(shi)時(shi)(shi)應盡量及時(shi)(shi)充(chong)電(dian)(dian)(dian)，如果(guo)新電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)量過(guo)低還持續使用的話，對電(dian)(dian)(dian)池(chi)的傷(shang)害比較(jiao)嚴重。日常使用電(dian)(dian)(dian)動(dong)車時(shi)(shi)建議充(chong)電(dian)(dian)(dian)方式：

1、每天的用電(dian)量在10%時，可(ke)以一周(zhou)充一次電(dian)；

2、每天(tian)的用電(dian)(dian)量在(zai)20%時，可以三天(tian)充一次電(dian)(dian)；

3、每(mei)天的用電(dian)量在(zai)30%時，可以兩天充(chong)一次電(dian)；

4、每(mei)天(tian)的用電量在40%以上時，可以一(yi)天(tian)充(chong)一(yi)次(ci)(ci)電，每(mei)次(ci)(ci)在6小時左右(you)。
