一、電動車電池硫化如何修復
1、水療法
對已硫(liu)化電(dian)(dian)(dian)池(chi),可以先(xian)將電(dian)(dian)(dian)池(chi)放電(dian)(dian)(dian),倒出原電(dian)(dian)(dian)解(jie)液(ye)(ye)并注(zhu)入密度(du)在(zai)1.10g/cm3以下(xia)較稀(xi)電(dian)(dian)(dian)解(jie)液(ye)(ye),即(ji)向(xiang)電(dian)(dian)(dian)池(chi)中(zhong)加水稀(xi)釋電(dian)(dian)(dian)解(jie)液(ye)(ye),以提(ti)高(gao)硫(liu)酸(suan)鉛的溶(rong)(rong)解(jie)度(du)。采用20h率以下(xia)的電(dian)(dian)(dian)流,在(zai)液(ye)(ye)溫不(bu)超過20℃~40℃的范圍內較長時間充(chong)電(dian)(dian)(dian),最后在(zai)充(chong)足(zu)電(dian)(dian)(dian)情(qing)況下(xia)用稍(shao)高(gao)電(dian)(dian)(dian)解(jie)液(ye)(ye)調(diao)整電(dian)(dian)(dian)池(chi)內電(dian)(dian)(dian)解(jie)液(ye)(ye)密度(du)至(zhi)標準溶(rong)(rong)液(ye)(ye)濃度(du),一般硫(liu)化現象(xiang)可解(jie)除(chu),容量恢復至(zhi)80%以上可認為修(xiu)復成功(gong)。
2、淺循環大電流(liu)充(chong)電法(fa)
對已硫化電(dian)(dian)池,采用大(da)電(dian)(dian)流5h率(lv)以內電(dian)(dian)流,對電(dian)(dian)池充(chong)電(dian)(dian)至稍過充(chong)狀態控制液溫不超過40度(du)為(wei)宜,然后放電(dian)(dian)30%,如此反復數(shu)次可(ke)減輕和(he)消除硫化現象(xiang)。
3、化學修復法
對已硫(liu)化(hua)電(dian)池(chi),倒掉(diao)原電(dian)解液(ye),加(jia)入(ru)純水與硫(liu)酸(suan)(suan)(suan)鈉、硫(liu)酸(suan)(suan)(suan)鉀、酒石酸(suan)(suan)(suan)等物(wu)質混合液(ye),采取正常充放電(dian)幾次(ci),然(ran)后倒出純水加(jia)入(ru)稍高(gao)密度(du)酸(suan)(suan)(suan)液(ye)調整電(dian)池(chi)內酸(suan)(suan)(suan)液(ye)至標準液(ye)濃度(du),容(rong)量恢復(fu)至80%以上可認為修復(fu)成功。
4、脈沖修復
對于硫化(hua)電(dian)(dian)池(chi),可用一些專用的脈沖修復儀(yi)對電(dian)(dian)池(chi)充放電(dian)(dian)數次來消(xiao)除(chu)硫化(hua)。
二、電動車電池壽命一般幾年
蓄(xu)電(dian)池使(shi)(shi)用(yong)時間(jian)遠(yuan)遠(yuan)超過(guo)正(zheng)常使(shi)(shi)用(yong)時間(jian)。蓄(xu)電(dian)池正(zheng)常可以使(shi)(shi)用(yong)1年多,用(yong)戶應根據使(shi)(shi)用(yong)的(de)(de)具(ju)體條件(jian)及運行(xing)狀(zhuang)況確定(ding)是否報廢,一(yi)般情況下,放電(dian)深度較大的(de)(de)使(shi)(shi)用(yong)壽(shou)命(ming)在1年左(zuo)右(you),放電(dian)深度在50%-70%的(de)(de)蓄(xu)電(dian)池壽(shou)命(ming)在1年半左(zuo)右(you)。個別廠家生產的(de)(de)蓄(xu)電(dian)池可以達到2年以上。 當出現以下現象時,也可以判斷為蓄(xu)電(dian)池壽(shou)命(ming)終止:電(dian)池實際(ji)放電(dian)容量(liang)低(di)于額定(ding)容量(liang)的(de)(de)60%左(zuo)右(you);蓄(xu)電(dian)池充電(dian)時,發熱(re)嚴重;性能不穩定(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同(tong),48v電池(chi)安數不同(tong)(10A400-500元(yuan);12A600-750元(yuan);15A750-900元(yuan);20A一千元(yuan)以上)。
