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)(dian)(dian)池，可(ke)以先將電(dian)(dian)(dian)(dian)(dian)池放電(dian)(dian)(dian)(dian)(dian)，倒(dao)出原電(dian)(dian)(dian)(dian)(dian)解液并注入密度(du)在1.10g/cm3以下較稀(xi)電(dian)(dian)(dian)(dian)(dian)解液，即(ji)向電(dian)(dian)(dian)(dian)(dian)池中加水稀(xi)釋電(dian)(dian)(dian)(dian)(dian)解液，以提高(gao)硫(liu)酸鉛(qian)的(de)溶解度(du)。采用20h率以下的(de)電(dian)(dian)(dian)(dian)(dian)流，在液溫不超過20℃～40℃的(de)范圍內(nei)較長時間(jian)充電(dian)(dian)(dian)(dian)(dian)，最(zui)后在充足電(dian)(dian)(dian)(dian)(dian)情況下用稍高(gao)電(dian)(dian)(dian)(dian)(dian)解液調(diao)整電(dian)(dian)(dian)(dian)(dian)池內(nei)電(dian)(dian)(dian)(dian)(dian)解液密度(du)至標(biao)準溶液濃度(du)，一般硫(liu)化(hua)現(xian)象可(ke)解除，容量恢復至80%以上(shang)可(ke)認為修復成功。

2、淺循環大電(dian)流充電(dian)法

對(dui)已硫(liu)化電(dian)(dian)池，采用大電(dian)(dian)流5h率以(yi)內電(dian)(dian)流，對(dui)電(dian)(dian)池充電(dian)(dian)至稍過充狀態(tai)控制液溫(wen)不(bu)超(chao)過40度為宜，然后(hou)放電(dian)(dian)30%，如(ru)此反復數次可減輕和消除硫(liu)化現象。

3、化學修復法

對已硫化電池，倒(dao)掉原電解(jie)液(ye)，加入(ru)純水(shui)與硫酸(suan)鈉(na)、硫酸(suan)鉀、酒石酸(suan)等(deng)物質混(hun)合(he)液(ye)，采(cai)取正常(chang)充放電幾次，然(ran)后(hou)倒(dao)出(chu)純水(shui)加入(ru)稍高密度(du)酸(suan)液(ye)調整(zheng)電池內酸(suan)液(ye)至(zhi)(zhi)標(biao)準液(ye)濃度(du)，容量恢復(fu)至(zhi)(zhi)80%以上可認為修復(fu)成功。

4、脈沖修復

對(dui)于硫化(hua)電(dian)池，可用一(yi)些(xie)專用的脈(mo)沖修復儀(yi)對(dui)電(dian)池充放(fang)電(dian)數(shu)次來消除硫化(hua)。

二、電動車電池壽命一般幾年

蓄(xu)電(dian)(dian)池(chi)(chi)使(shi)用(yong)(yong)時(shi)間遠遠超(chao)過正(zheng)常使(shi)用(yong)(yong)時(shi)間。蓄(xu)電(dian)(dian)池(chi)(chi)正(zheng)常可以(yi)使(shi)用(yong)(yong)1年多，用(yong)(yong)戶(hu)應(ying)根據使(shi)用(yong)(yong)的(de)具體條件及運(yun)行狀況確定是否(fou)報(bao)廢，一般情(qing)況下，放電(dian)(dian)深度較大(da)的(de)使(shi)用(yong)(yong)壽命(ming)在(zai)1年左右，放電(dian)(dian)深度在(zai)50%-70%的(de)蓄(xu)電(dian)(dian)池(chi)(chi)壽命(ming)在(zai)1年半左右。個別廠家(jia)生產(chan)的(de)蓄(xu)電(dian)(dian)池(chi)(chi)可以(yi)達到2年以(yi)上。 當出現以(yi)下現象時(shi)，也可以(yi)判斷為蓄(xu)電(dian)(dian)池(chi)(chi)壽命(ming)終(zhong)止：電(dian)(dian)池(chi)(chi)實際放電(dian)(dian)容(rong)(rong)量低于額定容(rong)(rong)量的(de)60%左右；蓄(xu)電(dian)(dian)池(chi)(chi)充電(dian)(dian)時(shi)，發熱嚴重；性(xing)能不(bu)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(chi)安數不同(tong)（10A400-500元(yuan)(yuan)；12A600-750元(yuan)(yuan)；15A750-900元(yuan)(yuan)；20A一(yi)千(qian)元(yuan)(yuan)以上）。
