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)電時(shi)間(jian)一般充(chong)(chong)(chong)多(duo)長為好,電動車鋰電池(chi)正確的充(chong)(chong)(chong)電方法,需要按照標準的時(shi)間(jian)和(he)程序充(chong)(chong)(chong)電,即(ji)使是前三次也(ye)必須如此進行(xing)。充(chong)(chong)(chong)電器(qi)指(zhi)示燈(deng)轉綠燈(deng)后,再充(chong)(chong)(chong)1-2小(xiao)時(shi)左右,即(ji)可停止充(chong)(chong)(chong)電工作。注意,不要進行(xing)超過12個小(xiao)時(shi)的超長充(chong)(chong)(chong)電,一般充(chong)(chong)(chong)電時(shi)間(jian)控制在3-5小(xiao)時(shi)左右。
電(dian)動車鋰電(dian)池充(chong)電(dian)器都是(shi)三(san)段式(shi)充(chong)電(dian),即(ji)分為恒壓(ya)階(jie)(jie)段、恒流階(jie)(jie)段、涓流階(jie)(jie)段。前(qian)兩階(jie)(jie)段是(shi)充(chong)電(dian)的主要(yao)階(jie)(jie)段,完(wan)成后電(dian)池基本充(chong)滿(man),燈會變(bian)綠,進入涓流階(jie)(jie)段,保(bao)護電(dian)池。這時不要(yao)拔下電(dian)源,繼續充(chong)電(dian)1-2小時,可以有效增加電(dian)池壽命(ming),但(dan)變(bian)綠后不要(yao)超過8小時。
一(yi)般(ban)電動車鋰電池充(chong)(chong)(chong)電,最好按(an)規格說(shuo)明書(shu)上面(mian)的(de)(de)要求來充(chong)(chong)(chong),如果(guo)沒有(you)了,要看鋰電池的(de)(de)容量和充(chong)(chong)(chong)電器的(de)(de)電流是多大,比如48V/20A的(de)(de)鋰電池,充(chong)(chong)(chong)電器是5A的(de)(de),就(jiu)要充(chong)(chong)(chong)4個(ge)(ge)小時多一(yi)點,而10A的(de)(de)充(chong)(chong)(chong)電器充(chong)(chong)(chong)兩個(ge)(ge)小時多一(yi)點,20A的(de)(de)充(chong)(chong)(chong)電器就(jiu)充(chong)(chong)(chong)一(yi)個(ge)(ge)小時。
一(yi)般(ban)給(gei)電(dian)動(dong)車的鋰電(dian)池充(chong)電(dian)的充(chong)電(dian)器,都是采用(yong)(yong)(yong)三段式(shi)充(chong)電(dian)模式(shi),當100%用(yong)(yong)(yong)完電(dian)的情況下,一(yi)般(ban)充(chong)電(dian)時(shi)(shi)間會(hui)在(zai)8~10小(xiao)時(shi)(shi),不要超過(guo)12小(xiao)時(shi)(shi)(對電(dian)池壽命會(hui)有影響)。也(ye)不建議每次(ci)使用(yong)(yong)(yong)都把電(dian)用(yong)(yong)(yong)完,一(yi)般(ban)建議用(yong)(yong)(yong)電(dian)量在(zai)70%左(zuo)右就要進行充(chong)電(dian)了,這時(shi)(shi)充(chong)電(dian)時(shi)(shi)間一(yi)般(ban)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(dian)(dian)(dian)動(dong)車(che)使(shi)用的(de)鋰(li)電(dian)(dian)(dian)池(chi)主要(yao)分為三(san)(san)大(da)類,一(yi)(yi)種是(shi)(shi)三(san)(san)元(yuan)鋰(li),這也是(shi)(shi)目(mu)前使(shi)用最多的(de)一(yi)(yi)種鋰(li)電(dian)(dian)(dian)池(chi);二(er)(er)是(shi)(shi)磷酸鐵鋰(li);三(san)(san)是(shi)(shi)鈦酸鋰(li),鈦酸鋰(li)使(shi)用的(de)人(ren)很少。一(yi)(yi)般(ban)新買的(de)電(dian)(dian)(dian)動(dong)車(che)第(di)一(yi)(yi)次(ci)充電(dian)(dian)(dian)時間需(xu)要(yao)8至10小時左右,第(di)二(er)(er)次(ci)、第(di)三(san)(san)次(ci)充電(dian)(dian)(dian)時間需(xu)要(yao)6至8小時左右。
通常情況(kuang)下電(dian)動車前(qian)3-5次電(dian)量過(guo)低時(shi)(shi)最好連續(xu)充電(dian)5小時(shi)(shi)以上,但不要超過(guo)12小時(shi)(shi)。當聽到電(dian)量過(guo)低提示(shi)時(shi)(shi)應盡(jin)量及時(shi)(shi)充電(dian),如果(guo)新電(dian)池(chi)電(dian)量過(guo)低還持續(xu)使用(yong)的(de)話,對電(dian)池(chi)的(de)傷害(hai)比較嚴重。日(ri)常使用(yong)電(dian)動車時(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)的用電量在20%時,可(ke)以三(san)天(tian)充一次電;
3、每天的用電(dian)量在30%時(shi),可以兩天充一次(ci)電(dian);
4、每天的用電量(liang)在40%以上時(shi),可以一(yi)天充一(yi)次(ci)電,每次(ci)在6小時(shi)左(zuo)右。
