一、電動車電池硫化如何修復

1、水療法

對已硫(liu)化(hua)電(dian)(dian)(dian)池(chi)，可(ke)以先將電(dian)(dian)(dian)池(chi)放電(dian)(dian)(dian)，倒出原電(dian)(dian)(dian)解液(ye)并注入密度(du)(du)在1.10g/cm3以下(xia)(xia)較稀(xi)電(dian)(dian)(dian)解液(ye)，即向電(dian)(dian)(dian)池(chi)中加水(shui)稀(xi)釋電(dian)(dian)(dian)解液(ye)，以提高(gao)硫(liu)酸(suan)鉛的溶(rong)解度(du)(du)。采用(yong)(yong)20h率以下(xia)(xia)的電(dian)(dian)(dian)流，在液(ye)溫不超(chao)過20℃～40℃的范圍內較長時間充電(dian)(dian)(dian)，最后(hou)在充足電(dian)(dian)(dian)情(qing)況下(xia)(xia)用(yong)(yong)稍高(gao)電(dian)(dian)(dian)解液(ye)調整電(dian)(dian)(dian)池(chi)內電(dian)(dian)(dian)解液(ye)密度(du)(du)至(zhi)標(biao)準溶(rong)液(ye)濃(nong)度(du)(du)，一般硫(liu)化(hua)現象(xiang)可(ke)解除，容量恢復至(zhi)80%以上可(ke)認為修復成功。

2、淺循環大電(dian)流(liu)充電(dian)法

對已硫化電(dian)池，采用大電(dian)流5h率以內電(dian)流，對電(dian)池充電(dian)至稍過(guo)(guo)充狀態控(kong)制液溫不(bu)超(chao)過(guo)(guo)40度為(wei)宜，然(ran)后放電(dian)30%，如此(ci)反(fan)復數(shu)次可(ke)減輕(qing)和(he)消除硫化現象(xiang)。

3、化學修復法

對已硫(liu)化電(dian)(dian)池，倒(dao)(dao)掉原(yuan)電(dian)(dian)解(jie)液，加(jia)入(ru)純水與硫(liu)酸鈉、硫(liu)酸鉀(jia)、酒石酸等物質混合液，采取(qu)正常充放電(dian)(dian)幾次，然(ran)后倒(dao)(dao)出純水加(jia)入(ru)稍(shao)高密度酸液調整電(dian)(dian)池內酸液至標準液濃度，容(rong)量恢復至80%以(yi)上可(ke)認為(wei)修(xiu)復成功。

4、脈沖修復

對(dui)(dui)于硫化電池(chi)，可(ke)用一些專用的脈沖修復儀對(dui)(dui)電池(chi)充(chong)放電數次來消除硫化。

二、電動車電池壽命一般幾年

蓄(xu)(xu)電(dian)(dian)池(chi)(chi)(chi)使(shi)(shi)用(yong)(yong)時(shi)(shi)間(jian)遠遠超過正常使(shi)(shi)用(yong)(yong)時(shi)(shi)間(jian)。蓄(xu)(xu)電(dian)(dian)池(chi)(chi)(chi)正常可(ke)以(yi)使(shi)(shi)用(yong)(yong)1年(nian)(nian)多，用(yong)(yong)戶應根據(ju)使(shi)(shi)用(yong)(yong)的(de)(de)具體條件及運行狀況確定是否(fou)報廢，一般情況下(xia)，放電(dian)(dian)深度(du)較大的(de)(de)使(shi)(shi)用(yong)(yong)壽(shou)命(ming)(ming)在(zai)1年(nian)(nian)左右(you)，放電(dian)(dian)深度(du)在(zai)50%-70%的(de)(de)蓄(xu)(xu)電(dian)(dian)池(chi)(chi)(chi)壽(shou)命(ming)(ming)在(zai)1年(nian)(nian)半左右(you)。個別廠(chang)家生產的(de)(de)蓄(xu)(xu)電(dian)(dian)池(chi)(chi)(chi)可(ke)以(yi)達到2年(nian)(nian)以(yi)上。 當出(chu)現以(yi)下(xia)現象(xiang)時(shi)(shi)，也(ye)可(ke)以(yi)判斷為蓄(xu)(xu)電(dian)(dian)池(chi)(chi)(chi)壽(shou)命(ming)(ming)終(zhong)止：電(dian)(dian)池(chi)(chi)(chi)實際放電(dian)(dian)容量低(di)于額定容量的(de)(de)60%左右(you)；蓄(xu)(xu)電(dian)(dian)池(chi)(chi)(chi)充電(dian)(dian)時(shi)(shi)，發熱嚴(yan)重；性(xing)能不穩定。

三、電動車電池48v多少錢

一組48V的電動車電池大概需要600-1000元，其中價格差異在于電動車電池品牌不同(tong)，48v電池安數(shu)不同(tong)（10A400-500元(yuan)(yuan)；12A600-750元(yuan)(yuan)；15A750-900元(yuan)(yuan)；20A一千元(yuan)(yuan)以上）。
