電動車電池行業簡介

一、電動車電池硫化如何修復

1、水療法

對(dui)已硫化電(dian)(dian)(dian)池，可以(yi)先將(jiang)電(dian)(dian)(dian)池放電(dian)(dian)(dian)，倒出原電(dian)(dian)(dian)解(jie)液(ye)(ye)并注入密度在(zai)1.10g/cm3以(yi)下(xia)較(jiao)稀(xi)電(dian)(dian)(dian)解(jie)液(ye)(ye)，即(ji)向電(dian)(dian)(dian)池中(zhong)加水稀(xi)釋(shi)電(dian)(dian)(dian)解(jie)液(ye)(ye)，以(yi)提高(gao)硫酸鉛(qian)的溶(rong)解(jie)度。采用20h率以(yi)下(xia)的電(dian)(dian)(dian)流，在(zai)液(ye)(ye)溫不超過20℃～40℃的范(fan)圍內較(jiao)長時間充電(dian)(dian)(dian)，最后在(zai)充足電(dian)(dian)(dian)情況(kuang)下(xia)用稍高(gao)電(dian)(dian)(dian)解(jie)液(ye)(ye)調(diao)整電(dian)(dian)(dian)池內電(dian)(dian)(dian)解(jie)液(ye)(ye)密度至標準溶(rong)液(ye)(ye)濃度，一(yi)般(ban)硫化現象可解(jie)除，容量恢復至80%以(yi)上可認為修復成功。

2、淺(qian)循環大電流充電法

對已硫(liu)化電(dian)池(chi)，采(cai)用大電(dian)流5h率以(yi)內電(dian)流，對電(dian)池(chi)充(chong)電(dian)至稍過充(chong)狀態控制液(ye)溫不超過40度為(wei)宜，然后放(fang)電(dian)30%，如此反復數次可(ke)減輕和消除硫(liu)化現象(xiang)。

3、化學修復法

對已(yi)硫(liu)(liu)化電池(chi)，倒掉(diao)原電解(jie)液(ye)(ye)(ye)，加(jia)入純水(shui)(shui)與硫(liu)(liu)酸(suan)鈉(na)、硫(liu)(liu)酸(suan)鉀、酒石酸(suan)等物質混合液(ye)(ye)(ye)，采取(qu)正常(chang)充放電幾次，然后(hou)倒出純水(shui)(shui)加(jia)入稍高密度(du)(du)酸(suan)液(ye)(ye)(ye)調整電池(chi)內酸(suan)液(ye)(ye)(ye)至(zhi)標準液(ye)(ye)(ye)濃度(du)(du)，容量(liang)恢復至(zhi)80%以(yi)上可認為修(xiu)復成(cheng)功。

4、脈沖修復

對于硫(liu)化(hua)(hua)電(dian)池，可用一些專用的脈沖修復儀對電(dian)池充放電(dian)數次(ci)來(lai)消除硫(liu)化(hua)(hua)。

二、電動車電池壽命一般幾年

蓄(xu)電(dian)(dian)(dian)池(chi)(chi)使(shi)用(yong)(yong)(yong)時間遠遠超(chao)過正常使(shi)用(yong)(yong)(yong)時間。蓄(xu)電(dian)(dian)(dian)池(chi)(chi)正常可(ke)以使(shi)用(yong)(yong)(yong)1年多，用(yong)(yong)(yong)戶(hu)應根(gen)據使(shi)用(yong)(yong)(yong)的(de)具(ju)體條件及運行狀況(kuang)確定是否(fou)報廢，一般(ban)情況(kuang)下，放電(dian)(dian)(dian)深(shen)度(du)(du)較大(da)的(de)使(shi)用(yong)(yong)(yong)壽(shou)命在(zai)1年左(zuo)(zuo)右，放電(dian)(dian)(dian)深(shen)度(du)(du)在(zai)50%-70%的(de)蓄(xu)電(dian)(dian)(dian)池(chi)(chi)壽(shou)命在(zai)1年半左(zuo)(zuo)右。個別廠家生產(chan)的(de)蓄(xu)電(dian)(dian)(dian)池(chi)(chi)可(ke)以達(da)到2年以上。 當出現以下現象時，也可(ke)以判斷為蓄(xu)電(dian)(dian)(dian)池(chi)(chi)壽(shou)命終止：電(dian)(dian)(dian)池(chi)(chi)實際(ji)放電(dian)(dian)(dian)容量低于額(e)定容量的(de)60%左(zuo)(zuo)右；蓄(xu)電(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)時，發熱嚴重(zhong)；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)；12A600-750元(yuan)；15A750-900元(yuan)；20A一千元(yuan)以(yi)上）。
