一、電動車鋰電池餓死了是什么意思

電(dian)(dian)(dian)(dian)動(dong)車在(zai)存(cun)放過程中，電(dian)(dian)(dian)(dian)池(chi)會有(you)自(zi)放電(dian)(dian)(dian)(dian)的(de)功能，如(ru)果電(dian)(dian)(dian)(dian)動(dong)車長時間(jian)沒有(you)騎，也(ye)沒有(you)充(chong)電(dian)(dian)(dian)(dian)，并且電(dian)(dian)(dian)(dian)動(dong)車坐(zuo)墊底下的(de)空氣開關也(ye)沒有(you)關，每天自(zi)放電(dian)(dian)(dian)(dian)約有(you)0.3%～0.5%，長時間(jian)沒有(you)充(chong)電(dian)(dian)(dian)(dian)導致(zhi)電(dian)(dian)(dian)(dian)動(dong)車持續慢(man)性放電(dian)(dian)(dian)(dian)，當電(dian)(dian)(dian)(dian)動(dong)車把電(dian)(dian)(dian)(dian)池(chi)的(de)電(dian)(dian)(dian)(dian)完全放完了(le)(le)，這(zhe)時候電(dian)(dian)(dian)(dian)池(chi)就容易虧電(dian)(dian)(dian)(dian)“餓死(si)”了(le)(le)。電(dian)(dian)(dian)(dian)池(chi)“餓死(si)”這(zhe)種情況(kuang)，一般情況(kuang)下電(dian)(dian)(dian)(dian)動(dong)車充(chong)電(dian)(dian)(dian)(dian)器無法(fa)充(chong)電(dian)(dian)(dian)(dian)，顯示狀態為綠燈，或者不停地閃(shan)爍，這(zhe)種情況(kuang)都屬于電(dian)(dian)(dian)(dian)池(chi)餓死(si)。

二、電動車鋰電池餓死了還能激活嗎

如果不嚴重(zhong)的話是可(ke)以(yi)激活的，但(dan)如果存放超過3個月以(yi)上的電(dian)瓶，一般比較難激活，超過3個月的建(jian)議重(zhong)新購買新電(dian)池來解決。

三、電動車鋰電池餓死了怎么激活

下(xia)面介紹六種比(bi)較好(hao)的方法，能將大部分(fen)的這(zhe)種“餓死(si)”的電(dian)瓶(ping)拯救過來。注意是大部分(fen)不是百(bai)分(fen)百(bai)。

1、開大燈充電

首先打(da)開電門(men)鑰匙，再(zai)開大(da)燈(deng)(deng)，開大(da)燈(deng)(deng)讓大(da)燈(deng)(deng)亮4-5個(ge)小時，這樣也可以(yi)(yi)激(ji)(ji)活電池(chi)，堅持激(ji)(ji)活以(yi)(yi)后(hou)，把(ba)大(da)燈(deng)(deng)關(guan)掉，然后(hou)顯(xian)示(shi)正常充(chong)電，可以(yi)(yi)繼(ji)續(xu)(xu)充(chong)電池(chi)充(chong)滿為(wei)止(zhi)，如(ru)果大(da)燈(deng)(deng)關(guan)掉以(yi)(yi)后(hou)這個(ge)充(chong)電器還是(shi)閃爍(shuo)，那(nei)繼(ji)續(xu)(xu)把(ba)這個(ge)大(da)燈(deng)(deng)打(da)開繼(ji)續(xu)(xu)充(chong)，我(wo)們充(chong)到(dao)什么時候(hou)？大(da)燈(deng)(deng)關(guan)掉，充(chong)電器上面顯(xian)示(shi)正常就(jiu)可以(yi)(yi)了。

2、串聯法

在整組電(dian)(dian)(dian)(dian)(dian)池(chi)上另(ling)外串(chuan)聯(lian)一個正常(chang)電(dian)(dian)(dian)(dian)(dian)壓(ya)的(de)(de)(de)12伏電(dian)(dian)(dian)(dian)(dian)池(chi)。比如說(shuo)，原車是48V-20AH的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)池(chi)，那我(wo)們再另(ling)外串(chuan)聯(lian)一塊(kuai)12V-20AH的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)池(chi)。一塊(kuai)電(dian)(dian)(dian)(dian)(dian)量充(chong)(chong)(chong)足(zu)的(de)(de)(de)12V電(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)壓(ya)有13V左右，串(chuan)聯(lian)之后(hou)(hou)能(neng)夠提升(sheng)整組電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)，然后(hou)(hou)再用原來的(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器進(jin)行充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，這樣(yang)的(de)(de)(de)話(hua)是可以將電(dian)(dian)(dian)(dian)(dian)充(chong)(chong)(chong)進(jin)去的(de)(de)(de)，插上充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器之后(hou)(hou)，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器是紅燈(deng)，此時(shi)可以將電(dian)(dian)(dian)(dian)(dian)充(chong)(chong)(chong)進(jin)去。等充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器轉為綠燈(deng)，就(jiu)把那塊(kuai)另(ling)外串(chuan)聯(lian)上去的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)池(chi)拿掉，然后(hou)(hou)再正常(chang)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)就(jiu)可以了。

3、并聯法

這種方法(fa)稍微麻煩一點。比如車輛原(yuan)來是48V-20AH的(de)(de)電(dian)(dian)(dian)池，我們(men)另外并聯一組，48V-20AH的(de)(de)電(dian)(dian)(dian)池。大家知道并聯電(dian)(dian)(dian)路各處的(de)(de)電(dian)(dian)(dian)壓(ya)(ya)是相等的(de)(de)，高(gao)的(de)(de)電(dian)(dian)(dian)壓(ya)(ya)端會向低的(de)(de)電(dian)(dian)(dian)壓(ya)(ya)端流(liu)入。這種方法(fa)也(ye)是很多(duo)電(dian)(dian)(dian)池經銷(xiao)商(shang)在檢測完全(quan)沒有電(dian)(dian)(dian)的(de)(de)電(dian)(dian)(dian)池所(suo)使用的(de)(de)方法(fa)。然后進行充(chong)電(dian)(dian)(dian)也(ye)可以(yi)達到充(chong)電(dian)(dian)(dian)的(de)(de)目的(de)(de)。這個原(yuan)理(li)(li)跟串(chuan)聯一個電(dian)(dian)(dian)池原(yuan)理(li)(li)差不多(duo)，也(ye)是將整組的(de)(de)電(dian)(dian)(dian)壓(ya)(ya)提升上去。

4、低壓充電法

選用小一型號的(de)(de)(de)充(chong)(chong)電(dian)器進行充(chong)(chong)電(dian)。比如說是一組60V-20AH的(de)(de)(de)電(dian)池，那么我們使(shi)用48V-20AH的(de)(de)(de)充(chong)(chong)電(dian)器進行充(chong)(chong)電(dian)。這(zhe)樣大部分的(de)(de)(de)情況下(xia)，也是可以(yi)充(chong)(chong)進去的(de)(de)(de)。待電(dian)池充(chong)(chong)電(dian)最少(shao)兩小時后工(gong)作電(dian)壓升高顯著，再換為60V-20AH的(de)(de)(de)充(chong)(chong)電(dian)頭做好電(dian)池充(chong)(chong)電(dian)。

5、單塊電池充電法

將(jiang)單(dan)(dan)塊電(dian)池(chi)(chi)用12伏(fu)的(de)電(dian)動車(che)充(chong)電(dian)器(qi)進行充(chong)電(dian)，可以(yi)將(jiang)電(dian)池(chi)(chi)激活，但這(zhe)種充(chong)電(dian)比較慢，一般要充(chong)7個(ge)小時以(yi)上，電(dian)池(chi)(chi)電(dian)壓(ya)才會緩慢回升到12V左右。如果(guo)全部單(dan)(dan)塊充(chong)很耗時間。

6、特殊充電器法

有的(de)充(chong)(chong)電(dian)器它(ta)是自動(dong)識別電(dian)池(chi)(chi)電(dian)壓的(de)，不(bu)管一組電(dian)池(chi)(chi)電(dian)壓有多少伏，都可(ke)以自動(dong)識別電(dian)壓，都可(ke)以充(chong)(chong)電(dian)進去(qu)。比(bi)如原車(che)是60V-20AH的(de)電(dian)池(chi)(chi)，現(xian)在只有30V不(bu)到，它(ta)照(zhao)樣可(ke)以往里面(mian)充(chong)(chong)電(dian)的(de)。隨著(zhu)電(dian)壓的(de)升(sheng)高(gao)(gao)，又全適應更高(gao)(gao)一階的(de)電(dian)壓，再給(gei)電(dian)池(chi)(chi)充(chong)(chong)電(dian)。

通過以上的方法就可以達到激活“餓死”的鋰電池的目的了，如果上述方法都行不通的話，還是要到專業的品牌維修店及時修理。最后還是需要提醒廣大電動車主要養成良好的充電習慣，千萬不要長時間不給電動車充電，容易造成電池餓死。鋰電池放著不用時，應每月電池充電一次，以增加鋰電池使用期限。只有養成良好的充電習慣，電池才能用的更久。
