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)池(chi)，可(ke)(ke)以(yi)(yi)(yi)先將電(dian)(dian)池(chi)放電(dian)(dian)，倒出(chu)原電(dian)(dian)解液并注入密度在1.10g/cm3以(yi)(yi)(yi)下較稀電(dian)(dian)解液，即(ji)向電(dian)(dian)池(chi)中加水稀釋電(dian)(dian)解液，以(yi)(yi)(yi)提高硫(liu)酸鉛的(de)溶解度。采用20h率以(yi)(yi)(yi)下的(de)電(dian)(dian)流，在液溫不超過20℃～40℃的(de)范圍內(nei)較長時間(jian)充(chong)電(dian)(dian)，最(zui)后在充(chong)足電(dian)(dian)情況(kuang)下用稍高電(dian)(dian)解液調整電(dian)(dian)池(chi)內(nei)電(dian)(dian)解液密度至(zhi)標準溶液濃(nong)度，一般硫(liu)化(hua)現象可(ke)(ke)解除，容量恢復(fu)至(zhi)80%以(yi)(yi)(yi)上可(ke)(ke)認為(wei)修復(fu)成(cheng)功。

2、淺循環大電流(liu)充(chong)電法

對已硫(liu)(liu)化電(dian)池(chi)，采(cai)用大電(dian)流5h率以內電(dian)流，對電(dian)池(chi)充電(dian)至稍過充狀態控制液溫不超過40度為宜，然后放電(dian)30%，如(ru)此反復數次可減輕和(he)消(xiao)除硫(liu)(liu)化現象。

3、化學修復法

對已硫(liu)化(hua)電池，倒(dao)掉(diao)原(yuan)電解液，加入純(chun)水與(yu)硫(liu)酸(suan)鈉、硫(liu)酸(suan)鉀、酒石酸(suan)等物質混合液，采(cai)取(qu)正常充(chong)放(fang)電幾次，然后倒(dao)出純(chun)水加入稍(shao)高密度酸(suan)液調整電池內酸(suan)液至標準液濃(nong)度，容量恢復(fu)至80%以(yi)上可認(ren)為修復(fu)成功。

4、脈沖修復

對(dui)于(yu)硫化電(dian)池，可用(yong)一(yi)些專用(yong)的脈沖修(xiu)復儀對(dui)電(dian)池充放電(dian)數次來消除硫化。

二、電動車電池壽命一般幾年

蓄電(dian)(dian)(dian)(dian)(dian)池(chi)使(shi)用(yong)時(shi)(shi)間(jian)遠遠超(chao)過正(zheng)常使(shi)用(yong)時(shi)(shi)間(jian)。蓄電(dian)(dian)(dian)(dian)(dian)池(chi)正(zheng)常可(ke)(ke)以(yi)(yi)使(shi)用(yong)1年(nian)多，用(yong)戶應根據使(shi)用(yong)的(de)(de)具體條(tiao)件及運行狀(zhuang)況確定(ding)(ding)是否報廢，一般情況下，放(fang)電(dian)(dian)(dian)(dian)(dian)深度較(jiao)大(da)的(de)(de)使(shi)用(yong)壽(shou)命(ming)(ming)在(zai)1年(nian)左(zuo)右，放(fang)電(dian)(dian)(dian)(dian)(dian)深度在(zai)50%-70%的(de)(de)蓄電(dian)(dian)(dian)(dian)(dian)池(chi)壽(shou)命(ming)(ming)在(zai)1年(nian)半(ban)左(zuo)右。個別廠家生產(chan)的(de)(de)蓄電(dian)(dian)(dian)(dian)(dian)池(chi)可(ke)(ke)以(yi)(yi)達(da)到(dao)2年(nian)以(yi)(yi)上(shang)。 當出現以(yi)(yi)下現象時(shi)(shi)，也可(ke)(ke)以(yi)(yi)判斷(duan)為蓄電(dian)(dian)(dian)(dian)(dian)池(chi)壽(shou)命(ming)(ming)終止：電(dian)(dian)(dian)(dian)(dian)池(chi)實(shi)際放(fang)電(dian)(dian)(dian)(dian)(dian)容量低于(yu)額定(ding)(ding)容量的(de)(de)60%左(zuo)右；蓄電(dian)(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)(dian)時(shi)(shi)，發(fa)熱嚴重；性能不(bu)穩(wen)定(ding)(ding)。

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(chi)安數不(bu)同（10A400-500元；12A600-750元；15A750-900元；20A一(yi)千元以上）。
