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(yi)硫化電(dian)(dian)(dian)(dian)(dian)池，可以先(xian)將(jiang)電(dian)(dian)(dian)(dian)(dian)池放電(dian)(dian)(dian)(dian)(dian)，倒出原電(dian)(dian)(dian)(dian)(dian)解(jie)液(ye)并注入密度(du)在1.10g/cm3以下較(jiao)稀電(dian)(dian)(dian)(dian)(dian)解(jie)液(ye)，即向電(dian)(dian)(dian)(dian)(dian)池中(zhong)加水稀釋電(dian)(dian)(dian)(dian)(dian)解(jie)液(ye)，以提高硫酸鉛的溶解(jie)度(du)。采用20h率(lv)以下的電(dian)(dian)(dian)(dian)(dian)流，在液(ye)溫不超(chao)過(guo)20℃～40℃的范圍內(nei)較(jiao)長時間充(chong)電(dian)(dian)(dian)(dian)(dian)，最(zui)后在充(chong)足電(dian)(dian)(dian)(dian)(dian)情況下用稍高電(dian)(dian)(dian)(dian)(dian)解(jie)液(ye)調整電(dian)(dian)(dian)(dian)(dian)池內(nei)電(dian)(dian)(dian)(dian)(dian)解(jie)液(ye)密度(du)至(zhi)(zhi)標準(zhun)溶液(ye)濃度(du)，一般(ban)硫化現象可解(jie)除，容量恢復至(zhi)(zhi)80%以上(shang)可認(ren)為修復成功(gong)。

2、淺循環大電(dian)(dian)流充電(dian)(dian)法

對已硫化電池(chi)，采用大電流5h率(lv)以內電流，對電池(chi)充電至稍過(guo)充狀態控制液溫不(bu)超過(guo)40度為宜(yi)，然(ran)后放(fang)電30%，如(ru)此反復(fu)數(shu)次(ci)可減輕和消(xiao)除硫化現象(xiang)。

3、化學修復法

對已硫(liu)化(hua)電(dian)池(chi)，倒掉原電(dian)解(jie)液(ye)(ye)，加入純水與(yu)硫(liu)酸(suan)鈉(na)、硫(liu)酸(suan)鉀、酒石酸(suan)等物質混合(he)液(ye)(ye)，采取正常(chang)充放(fang)電(dian)幾(ji)次，然后倒出純水加入稍高密度酸(suan)液(ye)(ye)調整電(dian)池(chi)內酸(suan)液(ye)(ye)至(zhi)標準(zhun)液(ye)(ye)濃(nong)度，容量(liang)恢復至(zhi)80%以(yi)上可認為修復成功(gong)。

4、脈沖修復

對于硫(liu)化電池(chi)，可用一些專用的脈沖(chong)修復儀對電池(chi)充放電數次來消除硫(liu)化。

二、電動車電池壽命一般幾年

蓄電(dian)(dian)(dian)(dian)池(chi)(chi)使(shi)(shi)用(yong)時間遠遠超過(guo)正常(chang)使(shi)(shi)用(yong)時間。蓄電(dian)(dian)(dian)(dian)池(chi)(chi)正常(chang)可以(yi)(yi)使(shi)(shi)用(yong)1年(nian)多，用(yong)戶應根據使(shi)(shi)用(yong)的(de)具(ju)體條件(jian)及運行狀況確定(ding)是(shi)否報廢(fei)，一般情況下(xia)，放(fang)(fang)電(dian)(dian)(dian)(dian)深(shen)度較大的(de)使(shi)(shi)用(yong)壽(shou)命(ming)在(zai)1年(nian)左(zuo)右，放(fang)(fang)電(dian)(dian)(dian)(dian)深(shen)度在(zai)50%-70%的(de)蓄電(dian)(dian)(dian)(dian)池(chi)(chi)壽(shou)命(ming)在(zai)1年(nian)半左(zuo)右。個別廠家生產的(de)蓄電(dian)(dian)(dian)(dian)池(chi)(chi)可以(yi)(yi)達到2年(nian)以(yi)(yi)上。 當出現以(yi)(yi)下(xia)現象時，也可以(yi)(yi)判(pan)斷為蓄電(dian)(dian)(dian)(dian)池(chi)(chi)壽(shou)命(ming)終止：電(dian)(dian)(dian)(dian)池(chi)(chi)實際放(fang)(fang)電(dian)(dian)(dian)(dian)容量(liang)低于(yu)額定(ding)容量(liang)的(de)60%左(zuo)右；蓄電(dian)(dian)(dian)(dian)池(chi)(chi)充電(dian)(dian)(dian)(dian)時，發熱嚴(yan)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電池安數不同(tong)（10A400-500元；12A600-750元；15A750-900元；20A一千元以上(shang)）。
