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)電(dian)時(shi)(shi)間(jian)(jian)一(yi)般充(chong)(chong)(chong)多(duo)長(chang)為(wei)好(hao)，電(dian)動車鋰(li)電(dian)池正確的充(chong)(chong)(chong)電(dian)方法(fa)，需(xu)要按(an)照(zhao)標準的時(shi)(shi)間(jian)(jian)和程序充(chong)(chong)(chong)電(dian)，即使是前三次也必(bi)須(xu)如此進行(xing)。充(chong)(chong)(chong)電(dian)器指(zhi)示燈轉綠燈后，再充(chong)(chong)(chong)1-2小時(shi)(shi)左右(you)，即可(ke)停止充(chong)(chong)(chong)電(dian)工(gong)作。注意，不要進行(xing)超過12個(ge)小時(shi)(shi)的超長(chang)充(chong)(chong)(chong)電(dian)，一(yi)般充(chong)(chong)(chong)電(dian)時(shi)(shi)間(jian)(jian)控(kong)制在3-5小時(shi)(shi)左右(you)。

電(dian)(dian)動(dong)車鋰電(dian)(dian)池(chi)充(chong)電(dian)(dian)器都是三段(duan)式(shi)充(chong)電(dian)(dian)，即分為恒(heng)壓(ya)階(jie)段(duan)、恒(heng)流(liu)階(jie)段(duan)、涓(juan)流(liu)階(jie)段(duan)。前兩階(jie)段(duan)是充(chong)電(dian)(dian)的(de)主要(yao)(yao)階(jie)段(duan)，完成(cheng)后電(dian)(dian)池(chi)基本充(chong)滿，燈會變綠，進入涓(juan)流(liu)階(jie)段(duan)，保護電(dian)(dian)池(chi)。這時不要(yao)(yao)拔下(xia)電(dian)(dian)源，繼續充(chong)電(dian)(dian)1-2小時，可(ke)以有效增加(jia)電(dian)(dian)池(chi)壽命，但變綠后不要(yao)(yao)超(chao)過8小時。

一般(ban)電(dian)(dian)(dian)動車(che)鋰(li)電(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)，最好按規(gui)格說明書上面的(de)要求(qiu)來充(chong)(chong)(chong)(chong)，如(ru)果沒(mei)有了，要看鋰(li)電(dian)(dian)(dian)池(chi)(chi)的(de)容量和(he)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)的(de)電(dian)(dian)(dian)流是多(duo)大(da)，比(bi)如(ru)48V/20A的(de)鋰(li)電(dian)(dian)(dian)池(chi)(chi)，充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)是5A的(de)，就要充(chong)(chong)(chong)(chong)4個(ge)小(xiao)時多(duo)一點，而10A的(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)充(chong)(chong)(chong)(chong)兩個(ge)小(xiao)時多(duo)一點，20A的(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)就充(chong)(chong)(chong)(chong)一個(ge)小(xiao)時。

一(yi)般給(gei)電(dian)(dian)(dian)動車(che)的(de)鋰電(dian)(dian)(dian)池充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)的(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器，都是采用三段(duan)式充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)模(mo)式，當100%用完電(dian)(dian)(dian)的(de)情況(kuang)下(xia)，一(yi)般充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)時(shi)間(jian)會在8~10小時(shi)，不要超(chao)過12小時(shi)（對電(dian)(dian)(dian)池壽命(ming)會有影響）。也不建議每次使用都把電(dian)(dian)(dian)用完，一(yi)般建議用電(dian)(dian)(dian)量(liang)在70%左右就要進行充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)了，這(zhe)時(shi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)時(shi)間(jian)一(yi)般在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(dong)車(che)使(shi)用(yong)(yong)的(de)鋰(li)電(dian)(dian)池(chi)主要(yao)分為三(san)(san)大(da)類(lei)，一(yi)種(zhong)(zhong)是三(san)(san)元鋰(li)，這(zhe)也(ye)是目前(qian)使(shi)用(yong)(yong)最(zui)多的(de)一(yi)種(zhong)(zhong)鋰(li)電(dian)(dian)池(chi)；二(er)是磷酸(suan)鐵鋰(li)；三(san)(san)是鈦(tai)(tai)酸(suan)鋰(li)，鈦(tai)(tai)酸(suan)鋰(li)使(shi)用(yong)(yong)的(de)人很少(shao)。一(yi)般新買的(de)電(dian)(dian)動(dong)車(che)第一(yi)次充(chong)電(dian)(dian)時(shi)間需要(yao)8至10小時(shi)左(zuo)右，第二(er)次、第三(san)(san)次充(chong)電(dian)(dian)時(shi)間需要(yao)6至8小時(shi)左(zuo)右。

通(tong)常情(qing)況下(xia)電(dian)(dian)動車前3-5次電(dian)(dian)量(liang)過(guo)低時最(zui)好連(lian)續充電(dian)(dian)5小(xiao)(xiao)時以上，但不要超過(guo)12小(xiao)(xiao)時。當聽到電(dian)(dian)量(liang)過(guo)低提示時應盡量(liang)及時充電(dian)(dian)，如果新電(dian)(dian)池電(dian)(dian)量(liang)過(guo)低還持(chi)續使用的(de)話，對電(dian)(dian)池的(de)傷害比較嚴(yan)重。日常使用電(dian)(dian)動車時建議充電(dian)(dian)方式(shi)：

1、每天的用(yong)電(dian)量在10%時，可以(yi)一周充一次電(dian)；

2、每天的用電量在20%時，可以三天充一次電；

3、每(mei)天的用電量在30%時，可以兩天充一(yi)次電；

4、每天的(de)用電(dian)(dian)量(liang)在(zai)40%以上時，可以一天充一次電(dian)(dian)，每次在(zai)6小時左(zuo)右。
