一、電動車電池硫化如何修復

1、水療法

對已(yi)硫化電(dian)池(chi)，可(ke)以(yi)(yi)先將電(dian)池(chi)放電(dian)，倒出原電(dian)解液(ye)并注入密度(du)(du)(du)在(zai)(zai)1.10g/cm3以(yi)(yi)下較(jiao)稀(xi)電(dian)解液(ye)，即向電(dian)池(chi)中(zhong)加(jia)水(shui)稀(xi)釋電(dian)解液(ye)，以(yi)(yi)提高(gao)硫酸鉛的(de)溶解度(du)(du)(du)。采(cai)用20h率以(yi)(yi)下的(de)電(dian)流，在(zai)(zai)液(ye)溫不超過20℃～40℃的(de)范圍內(nei)較(jiao)長時間充(chong)電(dian)，最后在(zai)(zai)充(chong)足電(dian)情況下用稍高(gao)電(dian)解液(ye)調整電(dian)池(chi)內(nei)電(dian)解液(ye)密度(du)(du)(du)至標準溶液(ye)濃度(du)(du)(du)，一般硫化現象可(ke)解除(chu)，容量恢復至80%以(yi)(yi)上可(ke)認為修復成功。

2、淺循環大(da)電流(liu)充電法(fa)

對已硫化(hua)電(dian)池，采(cai)用大電(dian)流5h率以(yi)內電(dian)流，對電(dian)池充電(dian)至稍過充狀(zhuang)態控(kong)制液溫不超過40度為宜(yi)，然(ran)后放電(dian)30%，如(ru)此反復(fu)數次可減(jian)輕和消除硫化(hua)現(xian)象。

3、化學修復法

對已硫化(hua)電池，倒(dao)掉原電解液(ye)，加入(ru)純水與(yu)硫酸(suan)(suan)鈉、硫酸(suan)(suan)鉀、酒石酸(suan)(suan)等物質混合液(ye)，采取正常充放電幾次，然后倒(dao)出(chu)純水加入(ru)稍高密度酸(suan)(suan)液(ye)調整電池內酸(suan)(suan)液(ye)至標(biao)準液(ye)濃度，容量恢復(fu)至80%以上可認(ren)為修復(fu)成功(gong)。

4、脈沖修復

對(dui)于硫化(hua)電池，可用一些專用的脈沖修復儀對(dui)電池充放電數次來消除硫化(hua)。

二、電動車電池壽命一般幾年

蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)使(shi)(shi)用(yong)(yong)(yong)(yong)時(shi)(shi)(shi)(shi)間(jian)遠(yuan)遠(yuan)超過正常(chang)使(shi)(shi)用(yong)(yong)(yong)(yong)時(shi)(shi)(shi)(shi)間(jian)。蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)正常(chang)可以使(shi)(shi)用(yong)(yong)(yong)(yong)1年多，用(yong)(yong)(yong)(yong)戶應根據使(shi)(shi)用(yong)(yong)(yong)(yong)的(de)具(ju)體條件(jian)及運(yun)行狀況(kuang)確定是否報廢，一般情況(kuang)下(xia)(xia)，放(fang)電(dian)(dian)(dian)(dian)(dian)深度較大的(de)使(shi)(shi)用(yong)(yong)(yong)(yong)壽(shou)命在1年左右(you)，放(fang)電(dian)(dian)(dian)(dian)(dian)深度在50%-70%的(de)蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)壽(shou)命在1年半左右(you)。個別廠(chang)家生產的(de)蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)可以達(da)到2年以上。 當出現(xian)以下(xia)(xia)現(xian)象時(shi)(shi)(shi)(shi)，也可以判斷為蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)壽(shou)命終止：電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)實際(ji)放(fang)電(dian)(dian)(dian)(dian)(dian)容(rong)量低于額定容(rong)量的(de)60%左右(you)；蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)時(shi)(shi)(shi)(shi)，發(fa)熱嚴重；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電池安數不同(tong)（10A400-500元(yuan)；12A600-750元(yuan)；15A750-900元(yuan)；20A一千元(yuan)以上）。
