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)液(ye)并注入密度(du)在1.10g/cm3以下較稀電(dian)(dian)(dian)解(jie)(jie)液(ye)，即向電(dian)(dian)(dian)池(chi)中加水稀釋電(dian)(dian)(dian)解(jie)(jie)液(ye)，以提高硫酸鉛(qian)的溶解(jie)(jie)度(du)。采(cai)用20h率(lv)以下的電(dian)(dian)(dian)流，在液(ye)溫不超(chao)過20℃～40℃的范圍(wei)內(nei)較長(chang)時間充(chong)電(dian)(dian)(dian)，最后(hou)在充(chong)足電(dian)(dian)(dian)情況下用稍高電(dian)(dian)(dian)解(jie)(jie)液(ye)調(diao)整電(dian)(dian)(dian)池(chi)內(nei)電(dian)(dian)(dian)解(jie)(jie)液(ye)密度(du)至標準溶液(ye)濃度(du)，一般(ban)硫化(hua)現象可(ke)解(jie)(jie)除，容量恢復(fu)至80%以上可(ke)認為(wei)修復(fu)成功。

2、淺循環大電(dian)流充電(dian)法

對(dui)(dui)已(yi)硫化電(dian)(dian)池，采(cai)用大電(dian)(dian)流5h率以內(nei)電(dian)(dian)流，對(dui)(dui)電(dian)(dian)池充電(dian)(dian)至稍(shao)過充狀態控制液溫(wen)不超過40度(du)為宜(yi)，然后(hou)放電(dian)(dian)30%，如此反復數次可減輕和(he)消除(chu)硫化現象。

3、化學修復法

對已硫(liu)化電池，倒掉(diao)原電解液，加入純水(shui)與硫(liu)酸(suan)鈉(na)、硫(liu)酸(suan)鉀、酒石酸(suan)等物質混合液，采取正常充(chong)放電幾次，然后倒出純水(shui)加入稍高密(mi)度酸(suan)液調整電池內酸(suan)液至標準液濃度，容量恢復(fu)至80%以(yi)上(shang)可認(ren)為(wei)修(xiu)復(fu)成功。

4、脈沖修復

對于硫化電(dian)池，可用一些專用的脈(mo)沖修復儀對電(dian)池充(chong)放電(dian)數次來(lai)消除硫化。

二、電動車電池壽命一般幾年

蓄(xu)電(dian)(dian)(dian)池(chi)(chi)(chi)使(shi)用(yong)(yong)(yong)時(shi)間(jian)遠遠超過正常使(shi)用(yong)(yong)(yong)時(shi)間(jian)。蓄(xu)電(dian)(dian)(dian)池(chi)(chi)(chi)正常可以(yi)使(shi)用(yong)(yong)(yong)1年(nian)(nian)多(duo)，用(yong)(yong)(yong)戶應(ying)根據使(shi)用(yong)(yong)(yong)的具體條件及(ji)運行狀況(kuang)確定(ding)是否報(bao)廢(fei)，一般情(qing)況(kuang)下(xia)(xia)，放電(dian)(dian)(dian)深度(du)較大的使(shi)用(yong)(yong)(yong)壽命(ming)(ming)在(zai)1年(nian)(nian)左右(you)，放電(dian)(dian)(dian)深度(du)在(zai)50%-70%的蓄(xu)電(dian)(dian)(dian)池(chi)(chi)(chi)壽命(ming)(ming)在(zai)1年(nian)(nian)半左右(you)。個別(bie)廠家生產的蓄(xu)電(dian)(dian)(dian)池(chi)(chi)(chi)可以(yi)達到2年(nian)(nian)以(yi)上。 當出現(xian)以(yi)下(xia)(xia)現(xian)象時(shi)，也(ye)可以(yi)判斷(duan)為蓄(xu)電(dian)(dian)(dian)池(chi)(chi)(chi)壽命(ming)(ming)終止(zhi)：電(dian)(dian)(dian)池(chi)(chi)(chi)實際放電(dian)(dian)(dian)容量(liang)低于額定(ding)容量(liang)的60%左右(you)；蓄(xu)電(dian)(dian)(dian)池(chi)(chi)(chi)充電(dian)(dian)(dian)時(shi)，發熱嚴重；性(xing)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，48v電池安數(shu)不同（10A400-500元(yuan)；12A600-750元(yuan)；15A750-900元(yuan)；20A一千元(yuan)以上）。
