一、電動車鋰電池充不進去電怎么辦
1、電動車鋰電(dian)(dian)(dian)(dian)池因為(wei)環(huan)境溫度(du)(du)變化大導(dao)致充不進電(dian)(dian)(dian)(dian),這(zhe)種(zhong)情況(kuang)多數是(shi)因為(wei)電(dian)(dian)(dian)(dian)動車(che)電(dian)(dian)(dian)(dian)池自身(shen)不是(shi)低(di)溫電(dian)(dian)(dian)(dian)池,在轉到低(di)溫環(huan)境下使用時,會(hui)因為(wei)溫度(du)(du)過低(di),導(dao)致電(dian)(dian)(dian)(dian)池內部凍結,致使電(dian)(dian)(dian)(dian)池內阻變大和化學活(huo)性(xing)降(jiang)低(di),使得放電(dian)(dian)(dian)(dian)能力急劇(ju)下降(jiang),甚(shen)至不放電(dian)(dian)(dian)(dian)。這(zhe)個可以轉到溫度(du)(du)適宜(yi)的(de)(de)地方,一(yi)段時間(jian)后,電(dian)(dian)(dian)(dian)池會(hui)恢復部分能力,常使用的(de)(de)話,電(dian)(dian)(dian)(dian)池會(hui)因為(wei)低(di)溫析(xi)鋰(li)導(dao)致壽(shou)命嚴重(zhong)衰減或報(bao)廢。
2、電(dian)(dian)(dian)(dian)動車鋰電(dian)(dian)(dian)(dian)池(chi)使用時(shi)經常(chang)完全用完電(dian)(dian)(dian)(dian)量,也(ye)就(jiu)是(shi)常(chang)說(shuo)的過(guo)(guo)多的深度放電(dian)(dian)(dian)(dian),這種行為(wei)造成的電(dian)(dian)(dian)(dian)池(chi)充不進電(dian)(dian)(dian)(dian)。如(ru)果充電(dian)(dian)(dian)(dian)器正常(chang),那么就(jiu)是(shi)電(dian)(dian)(dian)(dian)池(chi)因(yin)為(wei)常(chang)常(chang)處于(yu)高(gao)活躍狀態用電(dian)(dian)(dian)(dian)下,導致電(dian)(dian)(dian)(dian)池(chi)衰減(jian)過(guo)(guo)快,壽命用盡(jin),這個只能(neng)換電(dian)(dian)(dian)(dian)池(chi)了。
3、因為充電(dian)接口出現故(gu)障導致可能(neng)(neng)的(de)短路,使得電(dian)動車鋰電(dian)池(chi)保護(hu)板(ban)自(zi)行觸發保護(hu)功能(neng)(neng)而無法充電(dian),這個(ge)需(xu)要對充電(dian)接口做檢修(xiu)。
4、還有一個問(wen)題就是可能(neng)是電動車鋰電池(chi)的(de)(de)充電器(qi)出了(le)問(wen)題,因(yin)此建議先檢查(cha)充電器(qi)的(de)(de)問(wen)題。
二、電動車鋰電池怎么修復
電動車鋰電池一般壽命在2—3年左右,如果(guo)超過這個時間點就沒有維修(xiu)價值(zhi)了。電(dian)動車鋰電(dian)池一般主要故障有:失(shi)水、硫化(hua)、正極板(ban)軟化(hua)、短路(lu)、開路(lu)、起鼓等故障現象。關(guan)于電(dian)動車鋰電(dian)池修(xiu)復(fu)方(fang)法如下:
1、失(shi)水:需撬開電池上方的(de)(de)蓋板,用滴管吸入蒸(zheng)餾(liu)水由排氣孔注入電池,注意補水的(de)(de)原則是(shi)寧少勿多。
2、硫(liu)酸鹽(yan)化:將硫(liu)化的(de)(de)電池(chi)用修復(fu)儀修復(fu),采(cai)用模糊數字控(kong)制理論,通(tong)過測定(ding)電池(chi)狀態,在充(chong)、放電的(de)(de)同時(shi)(shi)不斷(duan)發出正負變(bian)頻微粒波,用10到(dao)20小時(shi)(shi)的(de)(de)時(shi)(shi)間,去除(chu)電池(chi)里結晶后變(bian)的(de)(de)堅硬的(de)(de)硫(liu)酸鉛。
3、正極板軟化:需(xu)將電(dian)池放(fang)(fang)電(dian)止10.5V后,用燈泡深放(fang)(fang)電(dian)1-5小時。然后用活(huo)(huo)化儀,活(huo)(huo)化修復。
4、短(duan)(duan)(duan)路:水電池(chi),可以打孔(kong)清晰,將短(duan)(duan)(duan)路的鉛粉(fen)弄(nong)出,電動車電池(chi)可以迅速短(duan)(duan)(duan)路正(zheng)負極(ji),將短(duan)(duan)(duan)路的地方燒斷(duan)。
5、開路(lu):100A檢測電池電壓(ya)0V為開路(lu),用單個測量的方(fang)(fang)法(fa),使用萬用表測量出開路(lu)的地(di)方(fang)(fang),焊好即可初步(bu)解決。
6、起(qi)鼓:鼓包的電池(chi)一般沒法修復,建議直接(jie)更(geng)換新電池(chi)來解決。
另外,車主也要平(ping)常注重保(bao)養電(dian)池,電(dian)動自行(xing)車在(zai)起步、載(zai)人、上坡時,最好用(yong)腳(jiao)蹬助力,盡(jin)量(liang)避免瞬間大電(dian)流放電(dian)。每(mei)隔1-3個月,對電(dian)瓶進(jin)行(xing)一次深放電(dian),會(hui)延長電(dian)瓶壽命。
