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)(dian)時(shi)間一般(ban)充(chong)(chong)(chong)(chong)多長為好，電(dian)(dian)(dian)(dian)動車鋰電(dian)(dian)(dian)(dian)池(chi)正確的充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)方法，需要按照標準的時(shi)間和程序充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)，即使是(shi)前(qian)三(san)次也必(bi)須如此進(jin)行。充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器指示燈轉綠(lv)燈后，再充(chong)(chong)(chong)(chong)1-2小時(shi)左右，即可停(ting)止充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)工作。注意，不要進(jin)行超(chao)(chao)過12個(ge)小時(shi)的超(chao)(chao)長充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)，一般(ban)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時(shi)間控(kong)制在3-5小時(shi)左右。

電(dian)動(dong)車鋰(li)電(dian)池充(chong)電(dian)器(qi)都(dou)是三段式充(chong)電(dian)，即(ji)分為(wei)恒壓(ya)階(jie)(jie)段、恒流階(jie)(jie)段、涓(juan)流階(jie)(jie)段。前兩(liang)階(jie)(jie)段是充(chong)電(dian)的(de)主要階(jie)(jie)段，完成后電(dian)池基本充(chong)滿，燈會(hui)變綠，進入涓(juan)流階(jie)(jie)段，保護電(dian)池。這時(shi)不(bu)要拔下電(dian)源，繼(ji)續充(chong)電(dian)1-2小(xiao)時(shi)，可以有效增加(jia)電(dian)池壽命(ming)，但變綠后不(bu)要超過8小(xiao)時(shi)。

一(yi)般電(dian)(dian)(dian)動車(che)鋰電(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)，最好按規格說明書上面的(de)要求來充，如(ru)果沒有了，要看鋰電(dian)(dian)(dian)池(chi)的(de)容(rong)量和充電(dian)(dian)(dian)器(qi)的(de)電(dian)(dian)(dian)流是(shi)多大，比如(ru)48V/20A的(de)鋰電(dian)(dian)(dian)池(chi)，充電(dian)(dian)(dian)器(qi)是(shi)5A的(de)，就要充4個(ge)小時多一(yi)點，而10A的(de)充電(dian)(dian)(dian)器(qi)充兩個(ge)小時多一(yi)點，20A的(de)充電(dian)(dian)(dian)器(qi)就充一(yi)個(ge)小時。

一般(ban)給(gei)電(dian)(dian)(dian)(dian)動(dong)車的鋰電(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)的充(chong)電(dian)(dian)(dian)(dian)器，都是(shi)采用(yong)(yong)三段式充(chong)電(dian)(dian)(dian)(dian)模(mo)式，當100%用(yong)(yong)完電(dian)(dian)(dian)(dian)的情(qing)況下(xia)，一般(ban)充(chong)電(dian)(dian)(dian)(dian)時(shi)間(jian)會(hui)在8~10小(xiao)時(shi)，不(bu)要(yao)超(chao)過12小(xiao)時(shi)（對電(dian)(dian)(dian)(dian)池(chi)壽命(ming)會(hui)有影響(xiang)）。也不(bu)建議每次使用(yong)(yong)都把電(dian)(dian)(dian)(dian)用(yong)(yong)完，一般(ban)建議用(yong)(yong)電(dian)(dian)(dian)(dian)量(liang)在70%左右就要(yao)進行充(chong)電(dian)(dian)(dian)(dian)了(le)，這(zhe)時(shi)充(chong)電(dian)(dian)(dian)(dian)時(shi)間(jian)一般(ban)在6~8小(xiao)時(shi)。

二、電動車鋰電池第一次充電要充多久

電(dian)動車(che)使用的(de)鋰電(dian)池(chi)(chi)主要分(fen)為三(san)大(da)類，一種是三(san)元(yuan)鋰，這也是目前使用最多的(de)一種鋰電(dian)池(chi)(chi)；二是磷酸(suan)(suan)鐵鋰；三(san)是鈦(tai)酸(suan)(suan)鋰，鈦(tai)酸(suan)(suan)鋰使用的(de)人很(hen)少。一般(ban)新買的(de)電(dian)動車(che)第(di)一次(ci)充(chong)電(dian)時間需要8至10小時左(zuo)右，第(di)二次(ci)、第(di)三(san)次(ci)充(chong)電(dian)時間需要6至8小時左(zuo)右。

通常(chang)情況下電動車前3-5次電量過(guo)低時(shi)(shi)最好連續(xu)充(chong)(chong)電5小(xiao)時(shi)(shi)以上，但不要超過(guo)12小(xiao)時(shi)(shi)。當聽到電量過(guo)低提示時(shi)(shi)應(ying)盡量及時(shi)(shi)充(chong)(chong)電，如果(guo)新電池電量過(guo)低還(huan)持續(xu)使(shi)用的(de)話，對電池的(de)傷害比(bi)較(jiao)嚴(yan)重(zhong)。日常(chang)使(shi)用電動車時(shi)(shi)建議充(chong)(chong)電方(fang)式：

1、每天的用電量在10%時，可(ke)以一(yi)周充一(yi)次電；

2、每(mei)天的用電量在20%時，可(ke)以(yi)三天充一次電；

3、每天(tian)的(de)用電量在(zai)30%時，可(ke)以兩(liang)天(tian)充一(yi)次電；

4、每(mei)天的用電量在40%以上時(shi)，可以一天充一次電，每(mei)次在6小時(shi)左(zuo)右。
