一、電動車電池硫化如何修復

1、水療法

對已硫(liu)化(hua)(hua)電(dian)(dian)池(chi)，可(ke)以(yi)(yi)先將電(dian)(dian)池(chi)放(fang)電(dian)(dian)，倒出原(yuan)電(dian)(dian)解(jie)(jie)(jie)液(ye)并注入(ru)密度在(zai)(zai)1.10g/cm3以(yi)(yi)下(xia)較稀電(dian)(dian)解(jie)(jie)(jie)液(ye)，即向電(dian)(dian)池(chi)中加水稀釋(shi)電(dian)(dian)解(jie)(jie)(jie)液(ye)，以(yi)(yi)提(ti)高硫(liu)酸鉛的(de)溶解(jie)(jie)(jie)度。采(cai)用(yong)20h率以(yi)(yi)下(xia)的(de)電(dian)(dian)流，在(zai)(zai)液(ye)溫不超過20℃～40℃的(de)范圍內較長(chang)時間充(chong)電(dian)(dian)，最后在(zai)(zai)充(chong)足電(dian)(dian)情(qing)況下(xia)用(yong)稍高電(dian)(dian)解(jie)(jie)(jie)液(ye)調(diao)整(zheng)電(dian)(dian)池(chi)內電(dian)(dian)解(jie)(jie)(jie)液(ye)密度至標(biao)準(zhun)溶液(ye)濃度，一般硫(liu)化(hua)(hua)現(xian)象可(ke)解(jie)(jie)(jie)除，容量(liang)恢復(fu)至80%以(yi)(yi)上可(ke)認為修復(fu)成功。

2、淺循環大電(dian)流充(chong)電(dian)法

對(dui)(dui)已硫化(hua)電(dian)(dian)池(chi)，采用大(da)電(dian)(dian)流5h率以內電(dian)(dian)流，對(dui)(dui)電(dian)(dian)池(chi)充(chong)電(dian)(dian)至稍過(guo)(guo)充(chong)狀態控制(zhi)液(ye)溫不超過(guo)(guo)40度為宜，然后放電(dian)(dian)30%，如(ru)此反復數次可減輕和消除硫化(hua)現象。

3、化學修復法

對已(yi)硫(liu)化(hua)電(dian)池，倒掉原電(dian)解液(ye)，加入純水(shui)與硫(liu)酸(suan)鈉、硫(liu)酸(suan)鉀、酒(jiu)石(shi)酸(suan)等物(wu)質混(hun)合液(ye)，采取(qu)正常充放電(dian)幾次，然后(hou)倒出純水(shui)加入稍高(gao)密度酸(suan)液(ye)調整電(dian)池內(nei)酸(suan)液(ye)至標準液(ye)濃度，容量恢復(fu)至80%以上可認為(wei)修復(fu)成功。

4、脈沖修復

對于硫化(hua)(hua)電池(chi)，可用(yong)一些專用(yong)的脈沖修復儀對電池(chi)充放電數次(ci)來(lai)消除硫化(hua)(hua)。

二、電動車電池壽命一般幾年

蓄(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)使(shi)用(yong)(yong)時(shi)間遠遠超(chao)過正常使(shi)用(yong)(yong)時(shi)間。蓄(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)正常可以使(shi)用(yong)(yong)1年(nian)(nian)多，用(yong)(yong)戶應(ying)根據(ju)使(shi)用(yong)(yong)的具(ju)體條(tiao)件及(ji)運行狀況確(que)定是否報(bao)廢，一般情況下，放電(dian)(dian)(dian)(dian)深度較大(da)的使(shi)用(yong)(yong)壽命(ming)(ming)在1年(nian)(nian)左(zuo)右，放電(dian)(dian)(dian)(dian)深度在50%-70%的蓄(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)壽命(ming)(ming)在1年(nian)(nian)半左(zuo)右。個別廠家生產(chan)的蓄(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)可以達(da)到2年(nian)(nian)以上。 當出現以下現象時(shi)，也可以判斷為蓄(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)壽命(ming)(ming)終止：電(dian)(dian)(dian)(dian)池(chi)(chi)實際放電(dian)(dian)(dian)(dian)容量低于(yu)額定容量的60%左(zuo)右；蓄(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)充電(dian)(dian)(dian)(dian)時(shi)，發熱嚴(yan)重；性能不(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(bu)同，48v電池安數不(bu)同（10A400-500元(yuan)(yuan)；12A600-750元(yuan)(yuan)；15A750-900元(yuan)(yuan)；20A一千元(yuan)(yuan)以上）。
