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)池(chi),可(ke)以先將電(dian)(dian)(dian)池(chi)放電(dian)(dian)(dian),倒出原電(dian)(dian)(dian)解(jie)(jie)(jie)液(ye)并注(zhu)入密(mi)度(du)(du)在(zai)1.10g/cm3以下(xia)(xia)較稀電(dian)(dian)(dian)解(jie)(jie)(jie)液(ye),即向電(dian)(dian)(dian)池(chi)中加水稀釋電(dian)(dian)(dian)解(jie)(jie)(jie)液(ye),以提(ti)高硫酸(suan)鉛(qian)的(de)(de)溶解(jie)(jie)(jie)度(du)(du)。采用20h率以下(xia)(xia)的(de)(de)電(dian)(dian)(dian)流,在(zai)液(ye)溫不(bu)超(chao)過20℃~40℃的(de)(de)范圍內(nei)(nei)較長時(shi)間充電(dian)(dian)(dian),最后在(zai)充足電(dian)(dian)(dian)情況下(xia)(xia)用稍(shao)高電(dian)(dian)(dian)解(jie)(jie)(jie)液(ye)調整(zheng)電(dian)(dian)(dian)池(chi)內(nei)(nei)電(dian)(dian)(dian)解(jie)(jie)(jie)液(ye)密(mi)度(du)(du)至(zhi)標準溶液(ye)濃度(du)(du),一般硫化(hua)現象(xiang)可(ke)解(jie)(jie)(jie)除,容量恢(hui)復至(zhi)80%以上可(ke)認為修復成功(gong)。
2、淺循環(huan)大電(dian)流充電(dian)法
對(dui)已硫化(hua)電(dian)池(chi),采用大電(dian)流(liu)5h率(lv)以內電(dian)流(liu),對(dui)電(dian)池(chi)充電(dian)至稍過充狀態控制(zhi)液溫不超(chao)過40度為宜,然后放電(dian)30%,如(ru)此反復數次(ci)可減輕和消除硫化(hua)現象。
3、化學修復法
對已硫化電(dian)池(chi),倒(dao)掉原電(dian)解液,加(jia)入純水與(yu)硫酸(suan)鈉、硫酸(suan)鉀、酒石酸(suan)等物(wu)質混合液,采取(qu)正常(chang)充放電(dian)幾(ji)次(ci),然后倒(dao)出純水加(jia)入稍(shao)高密度(du)酸(suan)液調整電(dian)池(chi)內酸(suan)液至標準液濃度(du),容量恢復(fu)至80%以上可(ke)認為修(xiu)復(fu)成功。
4、脈沖修復
對于硫(liu)化電池,可用(yong)一些(xie)專用(yong)的脈沖修(xiu)復儀對電池充放電數次來(lai)消除硫(liu)化。
二、電動車電池壽命一般幾年
蓄(xu)(xu)電(dian)(dian)池(chi)(chi)(chi)(chi)使用時(shi)間遠(yuan)遠(yuan)超過正常(chang)使用時(shi)間。蓄(xu)(xu)電(dian)(dian)池(chi)(chi)(chi)(chi)正常(chang)可以(yi)使用1年(nian)多(duo),用戶應根據(ju)使用的具體條件及(ji)運行狀況確定(ding)是否報(bao)廢(fei),一(yi)般(ban)情況下,放(fang)電(dian)(dian)深度較大的使用壽命(ming)在(zai)1年(nian)左右,放(fang)電(dian)(dian)深度在(zai)50%-70%的蓄(xu)(xu)電(dian)(dian)池(chi)(chi)(chi)(chi)壽命(ming)在(zai)1年(nian)半左右。個別廠家生產的蓄(xu)(xu)電(dian)(dian)池(chi)(chi)(chi)(chi)可以(yi)達到2年(nian)以(yi)上。 當出現以(yi)下現象時(shi),也可以(yi)判斷為蓄(xu)(xu)電(dian)(dian)池(chi)(chi)(chi)(chi)壽命(ming)終止:電(dian)(dian)池(chi)(chi)(chi)(chi)實際放(fang)電(dian)(dian)容量(liang)(liang)低于額(e)定(ding)容量(liang)(liang)的60%左右;蓄(xu)(xu)電(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)電(dian)(dian)時(shi),發熱嚴重;性能(neng)不穩(wen)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(an)數(shu)不同(tong)(10A400-500元(yuan);12A600-750元(yuan);15A750-900元(yuan);20A一(yi)千(qian)元(yuan)以上(shang))。
