一、電動車電池硫化如何修復
1、水療法
對已硫化(hua)電(dian)(dian)(dian)(dian)池(chi)(chi),可(ke)以先(xian)將電(dian)(dian)(dian)(dian)池(chi)(chi)放電(dian)(dian)(dian)(dian),倒出原電(dian)(dian)(dian)(dian)解(jie)(jie)液(ye)(ye)并注入(ru)密度(du)(du)在1.10g/cm3以下(xia)較(jiao)稀電(dian)(dian)(dian)(dian)解(jie)(jie)液(ye)(ye),即向電(dian)(dian)(dian)(dian)池(chi)(chi)中(zhong)加水稀釋電(dian)(dian)(dian)(dian)解(jie)(jie)液(ye)(ye),以提(ti)高(gao)硫酸(suan)鉛的(de)溶解(jie)(jie)度(du)(du)。采用20h率以下(xia)的(de)電(dian)(dian)(dian)(dian)流,在液(ye)(ye)溫不超過20℃~40℃的(de)范圍內較(jiao)長時間充(chong)電(dian)(dian)(dian)(dian),最后在充(chong)足電(dian)(dian)(dian)(dian)情況(kuang)下(xia)用稍高(gao)電(dian)(dian)(dian)(dian)解(jie)(jie)液(ye)(ye)調整電(dian)(dian)(dian)(dian)池(chi)(chi)內電(dian)(dian)(dian)(dian)解(jie)(jie)液(ye)(ye)密度(du)(du)至(zhi)標準溶液(ye)(ye)濃度(du)(du),一般(ban)硫化(hua)現(xian)象可(ke)解(jie)(jie)除(chu),容量恢復(fu)至(zhi)80%以上可(ke)認為修復(fu)成功(gong)。
2、淺(qian)循(xun)環(huan)大(da)電流充電法
對(dui)已(yi)硫化電(dian)(dian)池(chi),采用大電(dian)(dian)流(liu)5h率以內(nei)電(dian)(dian)流(liu),對(dui)電(dian)(dian)池(chi)充(chong)電(dian)(dian)至(zhi)稍(shao)過(guo)充(chong)狀態控(kong)制液溫不超過(guo)40度為宜,然后放(fang)電(dian)(dian)30%,如此反復數次可(ke)減輕和(he)消除(chu)硫化現象(xiang)。
3、化學修復法
對已硫(liu)化電池(chi),倒(dao)掉(diao)原電解液,加(jia)入(ru)(ru)純(chun)水與(yu)硫(liu)酸(suan)鈉、硫(liu)酸(suan)鉀、酒(jiu)石酸(suan)等物質混合液,采取正常充放電幾次,然后倒(dao)出純(chun)水加(jia)入(ru)(ru)稍(shao)高密度(du)酸(suan)液調整(zheng)電池(chi)內酸(suan)液至(zhi)標準(zhun)液濃度(du),容(rong)量恢復(fu)至(zhi)80%以上可認為修復(fu)成功。
4、脈沖修復
對于硫化電(dian)池(chi),可用一(yi)些專用的脈(mo)沖修復儀對電(dian)池(chi)充放電(dian)數次來消(xiao)除硫化。
二、電動車電池壽命一般幾年
蓄(xu)(xu)(xu)電(dian)(dian)池使(shi)用(yong)(yong)時(shi)間(jian)遠遠超過正常使(shi)用(yong)(yong)時(shi)間(jian)。蓄(xu)(xu)(xu)電(dian)(dian)池正常可(ke)以(yi)(yi)(yi)使(shi)用(yong)(yong)1年多,用(yong)(yong)戶(hu)應根據使(shi)用(yong)(yong)的(de)具體條件及(ji)運行狀況確定(ding)是否報廢,一(yi)般情況下,放(fang)電(dian)(dian)深度較大的(de)使(shi)用(yong)(yong)壽命在(zai)1年左右,放(fang)電(dian)(dian)深度在(zai)50%-70%的(de)蓄(xu)(xu)(xu)電(dian)(dian)池壽命在(zai)1年半左右。個別廠家生(sheng)產的(de)蓄(xu)(xu)(xu)電(dian)(dian)池可(ke)以(yi)(yi)(yi)達(da)到2年以(yi)(yi)(yi)上。 當(dang)出(chu)現(xian)以(yi)(yi)(yi)下現(xian)象時(shi),也可(ke)以(yi)(yi)(yi)判斷為蓄(xu)(xu)(xu)電(dian)(dian)池壽命終止:電(dian)(dian)池實際放(fang)電(dian)(dian)容量低于額定(ding)容量的(de)60%左右;蓄(xu)(xu)(xu)電(dian)(dian)池充(chong)電(dian)(dian)時(shi),發熱嚴重(zhong);性(xing)能不(bu)穩定(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電池安(an)數不(bu)同(10A400-500元(yuan);12A600-750元(yuan);15A750-900元(yuan);20A一(yi)千元(yuan)以上)。
