一、電動車鋰電池充電方法
1、需在適宜的環境進行充電
鋰電(dian)(dian)(dian)(dian)池(chi)在會充電(dian)(dian)(dian)(dian)時是一個(ge)化(hua)(hua)學反應過程(cheng),鋰離子(zi)電(dian)(dian)(dian)(dian)池(chi)由高(gao)活性的(de)正極材料和(he)有機電(dian)(dian)(dian)(dian)解(jie)液組成,在受(shou)熱(re)(re)條件(jian)下(xia)非常(chang)容(rong)易發生劇烈的(de)化(hua)(hua)學副反應,這(zhe)種反應將(jiang)產生大量的(de)熱(re)(re),甚(shen)至導致的(de)“熱(re)(re)失控”,所以需要有一個(ge)通風透氣(qi)、陰涼、溫(wen)度(du)適宜的(de)環境(jing)下(xia)進行充電(dian)(dian)(dian)(dian)散熱(re)(re)。
2、充電器要配套
充(chong)(chong)電(dian)(dian)器要與(yu)電(dian)(dian)池(chi)規格(ge)參數相(xiang)匹(pi)配(pei),電(dian)(dian)動車一般使(shi)用普遍的三段(duan)式充(chong)(chong)電(dian)(dian)器,第(di)一個(ge)階(jie)(jie)段(duan)叫(jiao)恒(heng)流階(jie)(jie)段(duan),第(di)二個(ge)階(jie)(jie)段(duan)叫(jiao)恒(heng)壓(ya)階(jie)(jie)段(duan),第(di)三個(ge)階(jie)(jie)段(duan)叫(jiao)涓流階(jie)(jie)段(duan)。從大(da)電(dian)(dian)流到小電(dian)(dian)流進行充(chong)(chong)電(dian)(dian),好的充(chong)(chong)電(dian)(dian)器也是會延長電(dian)(dian)池(chi)的使(shi)用壽命,盡(jin)量少用快充(chong)(chong),因為這(zhe)在一定程(cheng)度上會破壞電(dian)(dian)池(chi)的結構性能(neng)。
3、充電時長要控制、要及時充電
當電動車(che)電池(chi)剩余20%左右時,要及時充(chong)電,以免電池(chi)過度放(fang)電,放(fang)電過程也是一個硫(liu)化(hua)反(fan)應(ying)過程,硫(liu)化(hua)結(jie)晶聚積會影響電池(chi)的容(rong)量和性能,充(chong)電時長(chang)(chang)控制在8~10小(xiao)時,因為正(zheng)常情況8小(xiao)時左右應(ying)該就可(ke)以充(chong)滿電了,充(chong)電時長(chang)(chang)不宜過久。
另(ling)外騎行結束后(hou)(hou)不要立即進(jin)行充電(dian)(dian)(dian)(dian),此時電(dian)(dian)(dian)(dian)池還在放(fang)電(dian)(dian)(dian)(dian)狀態(tai),應(ying)冷卻(que)半小時再(zai)進(jin)行充電(dian)(dian)(dian)(dian),充電(dian)(dian)(dian)(dian)時插(cha)頭先(xian)插(cha)入(ru)電(dian)(dian)(dian)(dian)池端,然(ran)后(hou)(hou)再(zai)接通(tong)電(dian)(dian)(dian)(dian)源。長期(qi)不使用的電(dian)(dian)(dian)(dian)池要每(mei)個(ge)月進(jin)行充電(dian)(dian)(dian)(dian)1~2次,盡量有電(dian)(dian)(dian)(dian)狀態(tai)下(xia)放(fang)置存儲。
二、電動車鋰電池充電注意事項
1、首次充電
當我們(men)(men)剛買電(dian)動(dong)車(che)的(de)(de)時(shi)候,需(xu)要對(dui)電(dian)動(dong)車(che)進行首(shou)次(ci)(ci)充(chong)電(dian),首(shou)次(ci)(ci)充(chong)電(dian)的(de)(de)時(shi)間最好在(zai)8到12小時(shi)。因(yin)為從(cong)電(dian)動(dong)車(che)出廠(chang)開(kai)始,到我們(men)(men)手(shou)里中間有一段(duan)時(shi)間,那一段(duan)時(shi)間電(dian)動(dong)車(che)的(de)(de)電(dian)瓶會(hui)自己放電(dian),所以我們(men)(men)在(zai)拿到新電(dian)動(dong)車(che)時(shi),應該對(dui)電(dian)動(dong)車(che)進行首(shou)次(ci)(ci)充(chong)電(dian)。
2、正確把握充電時間
在我們使(shi)用(yong)電(dian)(dian)(dian)動(dong)車的(de)過程中,要根據我們使(shi)用(yong)的(de)實(shi)際情況(kuang),來把握好鋰(li)電(dian)(dian)(dian)池的(de)充電(dian)(dian)(dian)時間和次數。一般情況(kuang)下,如果電(dian)(dian)(dian)量表上的(de)紅(hong)燈(deng)和黃(huang)燈(deng)指(zhi)示亮了,就代表需要充電(dian)(dian)(dian)了,如果只有紅(hong)燈(deng)亮的(de)情況(kuang)下,我們應該立(li)即停車充電(dian)(dian)(dian),否則容易導致電(dian)(dian)(dian)瓶(ping)使(shi)用(yong)壽命減短。
3、充電時避免插頭發熱
如果(guo)插(cha)(cha)頭出現松動等(deng)問題,會導(dao)致(zhi)插(cha)(cha)頭發熱(re)(re),如果(guo)發熱(re)(re)的時間過長,就會導(dao)致(zhi)插(cha)(cha)頭短(duan)路或者是接(jie)觸不良,這是對充(chong)電(dian)器和電(dian)池的雙重傷害,所以(yi)我們在充(chong)電(dian)的時候要注意避免這樣(yang)的問題。
4、部分放電,不能過放電
我們要經常對(dui)鋰電(dian)池進行部分放(fang)(fang)電(dian),但是一(yi)定要注意(yi)不能過放(fang)(fang)電(dian),而且要避免完(wan)全放(fang)(fang)電(dian)的(de)情(qing)況,過放(fang)(fang)電(dian)會給(gei)電(dian)池帶來嚴重的(de)后果,反復的(de)過放(fang)(fang)電(dian)對(dui)電(dian)池的(de)影(ying)響非(fei)常大(da)。
5、充電要規律
在(zai)我們使用(yong)的過(guo)程(cheng)中,最好是每次使用(yong)過(guo)后都對(dui)電動車進行補電,或者(zhe)是充(chong)電,因為規律(lv)地給電池充(chong)電會(hui)使電瓶(ping)的使用(yong)壽命更加的長久。
