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)(dian)時間一般充(chong)多長為(wei)好,電(dian)(dian)動車鋰電(dian)(dian)池正(zheng)確的(de)充(chong)電(dian)(dian)方法,需(xu)要(yao)按照標準的(de)時間和程序充(chong)電(dian)(dian),即使是前三(san)次也必須如此進行(xing)(xing)。充(chong)電(dian)(dian)器指示燈(deng)轉(zhuan)綠燈(deng)后,再(zai)充(chong)1-2小時左右,即可停(ting)止充(chong)電(dian)(dian)工作。注(zhu)意,不(bu)要(yao)進行(xing)(xing)超過12個小時的(de)超長充(chong)電(dian)(dian),一般充(chong)電(dian)(dian)時間控(kong)制在3-5小時左右。
電(dian)動車鋰電(dian)池(chi)充(chong)電(dian)器都是(shi)三(san)段(duan)(duan)式充(chong)電(dian),即分為恒壓階(jie)段(duan)(duan)、恒流階(jie)段(duan)(duan)、涓流階(jie)段(duan)(duan)。前兩階(jie)段(duan)(duan)是(shi)充(chong)電(dian)的主要(yao)(yao)階(jie)段(duan)(duan),完成(cheng)后電(dian)池(chi)基本充(chong)滿,燈會變(bian)綠,進入涓流階(jie)段(duan)(duan),保護電(dian)池(chi)。這時不(bu)要(yao)(yao)拔(ba)下(xia)電(dian)源(yuan),繼續充(chong)電(dian)1-2小時,可以有效增加(jia)電(dian)池(chi)壽命(ming),但變(bian)綠后不(bu)要(yao)(yao)超過(guo)8小時。
一般電(dian)(dian)(dian)動車(che)鋰(li)電(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian),最好(hao)按(an)規格說明書(shu)上面(mian)的(de)(de)(de)要(yao)求來充(chong)(chong)(chong),如(ru)果沒(mei)有了,要(yao)看鋰(li)電(dian)(dian)(dian)池的(de)(de)(de)容(rong)量(liang)和(he)充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)的(de)(de)(de)電(dian)(dian)(dian)流是多(duo)大(da),比(bi)如(ru)48V/20A的(de)(de)(de)鋰(li)電(dian)(dian)(dian)池,充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)是5A的(de)(de)(de),就要(yao)充(chong)(chong)(chong)4個小(xiao)(xiao)時多(duo)一點,而(er)10A的(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)充(chong)(chong)(chong)兩個小(xiao)(xiao)時多(duo)一點,20A的(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)就充(chong)(chong)(chong)一個小(xiao)(xiao)時。
一(yi)般(ban)給電(dian)(dian)動車的鋰電(dian)(dian)池充(chong)電(dian)(dian)的充(chong)電(dian)(dian)器(qi),都(dou)是采用(yong)三段(duan)式充(chong)電(dian)(dian)模式,當100%用(yong)完電(dian)(dian)的情況下(xia),一(yi)般(ban)充(chong)電(dian)(dian)時(shi)間會(hui)(hui)在(zai)8~10小時(shi),不要超過12小時(shi)(對電(dian)(dian)池壽命會(hui)(hui)有影響)。也不建(jian)(jian)議(yi)每(mei)次使用(yong)都(dou)把電(dian)(dian)用(yong)完,一(yi)般(ban)建(jian)(jian)議(yi)用(yong)電(dian)(dian)量(liang)在(zai)70%左右就要進(jin)行(xing)充(chong)電(dian)(dian)了,這時(shi)充(chong)電(dian)(dian)時(shi)間一(yi)般(ban)在(zai)6~8小時(shi)。
二、電動車鋰電池第一次充電要充多久
電(dian)動車使用的鋰電(dian)池主要(yao)分為三大(da)類(lei),一(yi)種是(shi)(shi)三元(yuan)鋰,這也是(shi)(shi)目前使用最(zui)多(duo)的一(yi)種鋰電(dian)池;二(er)是(shi)(shi)磷(lin)酸(suan)鐵鋰;三是(shi)(shi)鈦酸(suan)鋰,鈦酸(suan)鋰使用的人很少。一(yi)般新買的電(dian)動車第(di)一(yi)次充電(dian)時(shi)間(jian)需要(yao)8至10小時(shi)左右,第(di)二(er)次、第(di)三次充電(dian)時(shi)間(jian)需要(yao)6至8小時(shi)左右。
通常(chang)情況下電(dian)動(dong)車(che)前3-5次(ci)電(dian)量過低(di)時(shi)最好連續(xu)充電(dian)5小時(shi)以上,但(dan)不要超過12小時(shi)。當聽到電(dian)量過低(di)提示時(shi)應盡(jin)量及時(shi)充電(dian),如果新電(dian)池電(dian)量過低(di)還持續(xu)使用的(de)話(hua),對電(dian)池的(de)傷害比較嚴重。日常(chang)使用電(dian)動(dong)車(che)時(shi)建議充電(dian)方式(shi):
1、每天的(de)用電量(liang)在10%時,可(ke)以(yi)一(yi)周充一(yi)次電;
2、每(mei)天的用(yong)電量在20%時,可以三天充(chong)一次電;
3、每(mei)天(tian)的用電量(liang)在(zai)30%時,可以(yi)兩天(tian)充(chong)一次電;
4、每天的用電量在(zai)40%以(yi)上時(shi),可以(yi)一天充一次電,每次在(zai)6小時(shi)左(zuo)右。
