一、電動車鋰電池餓死了是什么意思

電(dian)(dian)(dian)動(dong)車(che)(che)在存放(fang)(fang)過(guo)程中，電(dian)(dian)(dian)池(chi)會有(you)(you)自放(fang)(fang)電(dian)(dian)(dian)的功能，如果電(dian)(dian)(dian)動(dong)車(che)(che)長(chang)時間沒有(you)(you)騎，也(ye)沒有(you)(you)充(chong)電(dian)(dian)(dian)，并且(qie)電(dian)(dian)(dian)動(dong)車(che)(che)坐(zuo)墊底下的空氣開(kai)關也(ye)沒有(you)(you)關，每天自放(fang)(fang)電(dian)(dian)(dian)約有(you)(you)0.3%～0.5%，長(chang)時間沒有(you)(you)充(chong)電(dian)(dian)(dian)導致電(dian)(dian)(dian)動(dong)車(che)(che)持續慢性放(fang)(fang)電(dian)(dian)(dian)，當(dang)電(dian)(dian)(dian)動(dong)車(che)(che)把電(dian)(dian)(dian)池(chi)的電(dian)(dian)(dian)完全放(fang)(fang)完了，這(zhe)(zhe)時候電(dian)(dian)(dian)池(chi)就容易虧(kui)電(dian)(dian)(dian)“餓(e)死”了。電(dian)(dian)(dian)池(chi)“餓(e)死”這(zhe)(zhe)種(zhong)情(qing)況(kuang)，一般(ban)情(qing)況(kuang)下電(dian)(dian)(dian)動(dong)車(che)(che)充(chong)電(dian)(dian)(dian)器無法(fa)充(chong)電(dian)(dian)(dian)，顯示狀(zhuang)態為綠燈，或者不(bu)停地閃爍，這(zhe)(zhe)種(zhong)情(qing)況(kuang)都屬(shu)于電(dian)(dian)(dian)池(chi)餓(e)死。

二、電動車鋰電池餓死了還能激活嗎

如果不嚴重(zhong)的(de)話是(shi)可以激活的(de)，但如果存放超過3個月(yue)以上的(de)電瓶，一般比較(jiao)難(nan)激活，超過3個月(yue)的(de)建(jian)議重(zhong)新購買(mai)新電池來解(jie)決。

三、電動車鋰電池餓死了怎么激活

下面(mian)介紹六種比較好的(de)方法，能(neng)將大部(bu)(bu)分(fen)(fen)的(de)這種“餓(e)死”的(de)電瓶拯救過來。注意是(shi)大部(bu)(bu)分(fen)(fen)不是(shi)百分(fen)(fen)百。

1、開大燈充電

首先打開電(dian)(dian)門鑰匙，再開大(da)(da)燈，開大(da)(da)燈讓大(da)(da)燈亮(liang)4-5個(ge)小時(shi)，這樣也可(ke)以激(ji)活電(dian)(dian)池(chi)，堅持激(ji)活以后，把(ba)大(da)(da)燈關掉，然后顯(xian)示正(zheng)常充(chong)電(dian)(dian)，可(ke)以繼(ji)續(xu)充(chong)電(dian)(dian)池(chi)充(chong)滿為止，如果大(da)(da)燈關掉以后這個(ge)充(chong)電(dian)(dian)器還是(shi)閃爍，那繼(ji)續(xu)把(ba)這個(ge)大(da)(da)燈打開繼(ji)續(xu)充(chong)，我(wo)們充(chong)到(dao)什么(me)時(shi)候？大(da)(da)燈關掉，充(chong)電(dian)(dian)器上(shang)面顯(xian)示正(zheng)常就可(ke)以了。

2、串聯法

在整組電(dian)(dian)(dian)(dian)池(chi)上另(ling)外串(chuan)聯一(yi)個正常(chang)電(dian)(dian)(dian)(dian)壓的12伏電(dian)(dian)(dian)(dian)池(chi)。比如說(shuo)，原車是(shi)(shi)48V-20AH的電(dian)(dian)(dian)(dian)池(chi)，那我們(men)再(zai)另(ling)外串(chuan)聯一(yi)塊12V-20AH的電(dian)(dian)(dian)(dian)池(chi)。一(yi)塊電(dian)(dian)(dian)(dian)量充(chong)足的12V電(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)壓有13V左右(you)，串(chuan)聯之后(hou)能(neng)夠提升整組電(dian)(dian)(dian)(dian)池(chi)的電(dian)(dian)(dian)(dian)壓，然(ran)后(hou)再(zai)用原來的充(chong)電(dian)(dian)(dian)(dian)器(qi)進行充(chong)電(dian)(dian)(dian)(dian)，這(zhe)樣的話(hua)是(shi)(shi)可以(yi)將電(dian)(dian)(dian)(dian)充(chong)進去的，插上充(chong)電(dian)(dian)(dian)(dian)器(qi)之后(hou)，充(chong)電(dian)(dian)(dian)(dian)器(qi)是(shi)(shi)紅燈，此時可以(yi)將電(dian)(dian)(dian)(dian)充(chong)進去。等充(chong)電(dian)(dian)(dian)(dian)器(qi)轉為綠燈，就把那塊另(ling)外串(chuan)聯上去的電(dian)(dian)(dian)(dian)池(chi)拿(na)掉，然(ran)后(hou)再(zai)正常(chang)充(chong)電(dian)(dian)(dian)(dian)就可以(yi)了。

3、并聯法

這(zhe)種方法(fa)稍微(wei)麻煩一(yi)點。比如(ru)車(che)輛原(yuan)來(lai)是(shi)48V-20AH的(de)(de)電(dian)(dian)(dian)(dian)(dian)池，我們另外并聯(lian)一(yi)組，48V-20AH的(de)(de)電(dian)(dian)(dian)(dian)(dian)池。大(da)家知道(dao)并聯(lian)電(dian)(dian)(dian)(dian)(dian)路各處的(de)(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)是(shi)相等的(de)(de)，高的(de)(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)端會向低的(de)(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)端流(liu)入。這(zhe)種方法(fa)也(ye)是(shi)很多電(dian)(dian)(dian)(dian)(dian)池經銷(xiao)商在檢(jian)測完全沒有電(dian)(dian)(dian)(dian)(dian)的(de)(de)電(dian)(dian)(dian)(dian)(dian)池所(suo)使(shi)用的(de)(de)方法(fa)。然后進行充電(dian)(dian)(dian)(dian)(dian)也(ye)可(ke)以達到充電(dian)(dian)(dian)(dian)(dian)的(de)(de)目的(de)(de)。這(zhe)個原(yuan)理(li)跟串聯(lian)一(yi)個電(dian)(dian)(dian)(dian)(dian)池原(yuan)理(li)差(cha)不多，也(ye)是(shi)將整(zheng)組的(de)(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)提(ti)升上(shang)去(qu)。

4、低壓充電法

選用(yong)小一(yi)型號的(de)充(chong)(chong)(chong)電(dian)(dian)(dian)器進行充(chong)(chong)(chong)電(dian)(dian)(dian)。比(bi)如說是一(yi)組60V-20AH的(de)電(dian)(dian)(dian)池(chi)，那么我們使用(yong)48V-20AH的(de)充(chong)(chong)(chong)電(dian)(dian)(dian)器進行充(chong)(chong)(chong)電(dian)(dian)(dian)。這樣大部分的(de)情(qing)況下，也是可(ke)以充(chong)(chong)(chong)進去的(de)。待電(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)最(zui)少(shao)兩(liang)小時后(hou)工(gong)作電(dian)(dian)(dian)壓(ya)升高顯著，再換(huan)為60V-20AH的(de)充(chong)(chong)(chong)電(dian)(dian)(dian)頭做(zuo)好(hao)電(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)。

5、單塊電池充電法

將單塊電(dian)池用(yong)12伏的(de)電(dian)動車充(chong)(chong)電(dian)器進行充(chong)(chong)電(dian)，可以(yi)將電(dian)池激活，但這種充(chong)(chong)電(dian)比較慢，一般要充(chong)(chong)7個小時以(yi)上(shang)，電(dian)池電(dian)壓才會緩慢回升到12V左右。如果全(quan)部單塊充(chong)(chong)很耗時間。

6、特殊充電器法

有(you)的(de)充(chong)電(dian)(dian)器它是自動(dong)識別電(dian)(dian)池(chi)電(dian)(dian)壓(ya)的(de)，不管一(yi)(yi)組電(dian)(dian)池(chi)電(dian)(dian)壓(ya)有(you)多少(shao)伏，都可以(yi)自動(dong)識別電(dian)(dian)壓(ya)，都可以(yi)充(chong)電(dian)(dian)進去。比如原車是60V-20AH的(de)電(dian)(dian)池(chi)，現在只有(you)30V不到，它照樣可以(yi)往(wang)里面(mian)充(chong)電(dian)(dian)的(de)。隨著電(dian)(dian)壓(ya)的(de)升(sheng)高，又全(quan)適(shi)應(ying)更(geng)高一(yi)(yi)階的(de)電(dian)(dian)壓(ya)，再給(gei)電(dian)(dian)池(chi)充(chong)電(dian)(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(li)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。
