一、電動車電池硫化如何修復

1、水療法

對已硫化電(dian)(dian)(dian)池(chi)，可(ke)以(yi)先將電(dian)(dian)(dian)池(chi)放電(dian)(dian)(dian)，倒出原電(dian)(dian)(dian)解(jie)液并注入密(mi)度在1.10g/cm3以(yi)下較(jiao)稀電(dian)(dian)(dian)解(jie)液，即向電(dian)(dian)(dian)池(chi)中(zhong)加(jia)水稀釋電(dian)(dian)(dian)解(jie)液，以(yi)提(ti)高硫酸鉛的(de)溶解(jie)度。采用20h率以(yi)下的(de)電(dian)(dian)(dian)流，在液溫不超過20℃～40℃的(de)范圍內較(jiao)長時間充(chong)電(dian)(dian)(dian)，最后在充(chong)足電(dian)(dian)(dian)情況下用稍高電(dian)(dian)(dian)解(jie)液調整電(dian)(dian)(dian)池(chi)內電(dian)(dian)(dian)解(jie)液密(mi)度至標(biao)準溶液濃度，一(yi)般硫化現象(xiang)可(ke)解(jie)除，容(rong)量恢復至80%以(yi)上可(ke)認為(wei)修(xiu)復成功。

2、淺循環大電(dian)(dian)流充電(dian)(dian)法

對(dui)(dui)已硫化(hua)電池(chi)，采用大(da)電流5h率以(yi)內電流，對(dui)(dui)電池(chi)充電至稍過充狀態控(kong)制液溫不(bu)超過40度為(wei)宜，然后放電30%，如此(ci)反復數次(ci)可減輕(qing)和(he)消除硫化(hua)現象。

3、化學修復法

對已硫(liu)(liu)化(hua)電池(chi)，倒掉原電解液(ye)，加入純(chun)水與硫(liu)(liu)酸(suan)鈉、硫(liu)(liu)酸(suan)鉀、酒石酸(suan)等物質混合(he)液(ye)，采取(qu)正常充放(fang)電幾次，然后倒出純(chun)水加入稍高密度(du)酸(suan)液(ye)調(diao)整電池(chi)內酸(suan)液(ye)至標(biao)準液(ye)濃(nong)度(du)，容量恢復至80%以上(shang)可認為(wei)修復成功(gong)。

4、脈沖修復

對(dui)(dui)于硫化電(dian)池，可用(yong)一些(xie)專用(yong)的脈沖(chong)修復儀對(dui)(dui)電(dian)池充(chong)放電(dian)數次來消(xiao)除硫化。

二、電動車電池壽命一般幾年

蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)使(shi)(shi)用(yong)時(shi)間(jian)遠(yuan)遠(yuan)超(chao)過(guo)正(zheng)常使(shi)(shi)用(yong)時(shi)間(jian)。蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)正(zheng)常可以使(shi)(shi)用(yong)1年(nian)多(duo)，用(yong)戶(hu)應(ying)根據使(shi)(shi)用(yong)的(de)具體條件及運行狀(zhuang)況確(que)定是(shi)否報廢，一般(ban)情(qing)況下(xia)，放電(dian)(dian)(dian)(dian)深(shen)(shen)度(du)較大(da)的(de)使(shi)(shi)用(yong)壽命(ming)(ming)在1年(nian)左(zuo)右，放電(dian)(dian)(dian)(dian)深(shen)(shen)度(du)在50%-70%的(de)蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)壽命(ming)(ming)在1年(nian)半左(zuo)右。個別廠家(jia)生產的(de)蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)可以達(da)到2年(nian)以上(shang)。 當出現以下(xia)現象時(shi)，也可以判斷為蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)壽命(ming)(ming)終止：電(dian)(dian)(dian)(dian)池(chi)實際放電(dian)(dian)(dian)(dian)容(rong)量(liang)(liang)低于額定容(rong)量(liang)(liang)的(de)60%左(zuo)右；蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)時(shi)，發熱嚴重；性能不穩定。

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(bu)同，48v電(dian)池安數(shu)不(bu)同（10A400-500元；12A600-750元；15A750-900元；20A一千元以上）。
