一、電動車鋰電池餓死了是什么意思

電(dian)(dian)動(dong)車在存放(fang)(fang)過程(cheng)中，電(dian)(dian)池(chi)會(hui)有(you)(you)(you)(you)自放(fang)(fang)電(dian)(dian)的功能，如果電(dian)(dian)動(dong)車長時間沒(mei)有(you)(you)(you)(you)騎(qi)，也(ye)沒(mei)有(you)(you)(you)(you)充電(dian)(dian)，并且電(dian)(dian)動(dong)車坐墊底下的空氣開關(guan)(guan)也(ye)沒(mei)有(you)(you)(you)(you)關(guan)(guan)，每(mei)天(tian)自放(fang)(fang)電(dian)(dian)約有(you)(you)(you)(you)0.3%～0.5%，長時間沒(mei)有(you)(you)(you)(you)充電(dian)(dian)導致電(dian)(dian)動(dong)車持續慢性放(fang)(fang)電(dian)(dian)，當電(dian)(dian)動(dong)車把電(dian)(dian)池(chi)的電(dian)(dian)完全放(fang)(fang)完了，這時候電(dian)(dian)池(chi)就容易虧電(dian)(dian)“餓(e)死”了。電(dian)(dian)池(chi)“餓(e)死”這種情(qing)況(kuang)，一般情(qing)況(kuang)下電(dian)(dian)動(dong)車充電(dian)(dian)器無法(fa)充電(dian)(dian)，顯示狀態(tai)為綠燈(deng)，或者不停地(di)閃爍，這種情(qing)況(kuang)都屬于電(dian)(dian)池(chi)餓(e)死。

二、電動車鋰電池餓死了還能激活嗎

如(ru)果(guo)不嚴重的話是可以激活(huo)的，但如(ru)果(guo)存放超過3個月以上的電瓶，一般比較(jiao)難激活(huo)，超過3個月的建議重新購買新電池來(lai)解(jie)決。

三、電動車鋰電池餓死了怎么激活

下面介紹六種(zhong)比較好的(de)方(fang)法，能將大部(bu)分(fen)(fen)的(de)這種(zhong)“餓(e)死”的(de)電(dian)瓶拯(zheng)救過來(lai)。注(zhu)意是(shi)大部(bu)分(fen)(fen)不是(shi)百(bai)分(fen)(fen)百(bai)。

1、開大燈充電

首先打開電(dian)門鑰(yao)匙，再開大(da)燈，開大(da)燈讓(rang)大(da)燈亮4-5個(ge)小時，這(zhe)樣也可(ke)(ke)以激(ji)活電(dian)池(chi)，堅(jian)持激(ji)活以后(hou)，把大(da)燈關掉，然(ran)后(hou)顯(xian)示正常(chang)充(chong)電(dian)，可(ke)(ke)以繼續(xu)充(chong)電(dian)池(chi)充(chong)滿為止，如(ru)果大(da)燈關掉以后(hou)這(zhe)個(ge)充(chong)電(dian)器(qi)還是(shi)閃爍，那繼續(xu)把這(zhe)個(ge)大(da)燈打開繼續(xu)充(chong)，我們(men)充(chong)到什么時候？大(da)燈關掉，充(chong)電(dian)器(qi)上面顯(xian)示正常(chang)就可(ke)(ke)以了。

2、串聯法

在整組電(dian)(dian)(dian)(dian)池(chi)(chi)上另外串聯(lian)(lian)一個正常電(dian)(dian)(dian)(dian)壓的(de)(de)12伏電(dian)(dian)(dian)(dian)池(chi)(chi)。比如說，原車(che)是48V-20AH的(de)(de)電(dian)(dian)(dian)(dian)池(chi)(chi)，那(nei)我們(men)再(zai)另外串聯(lian)(lian)一塊12V-20AH的(de)(de)電(dian)(dian)(dian)(dian)池(chi)(chi)。一塊電(dian)(dian)(dian)(dian)量充(chong)足(zu)的(de)(de)12V電(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)壓有13V左右，串聯(lian)(lian)之(zhi)后(hou)能(neng)夠提(ti)升整組電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)電(dian)(dian)(dian)(dian)壓，然后(hou)再(zai)用原來的(de)(de)充(chong)電(dian)(dian)(dian)(dian)器(qi)進行充(chong)電(dian)(dian)(dian)(dian)，這樣的(de)(de)話(hua)是可(ke)以(yi)將電(dian)(dian)(dian)(dian)充(chong)進去的(de)(de)，插(cha)上充(chong)電(dian)(dian)(dian)(dian)器(qi)之(zhi)后(hou)，充(chong)電(dian)(dian)(dian)(dian)器(qi)是紅燈，此時可(ke)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(lv)燈，就把那(nei)塊另外串聯(lian)(lian)上去的(de)(de)電(dian)(dian)(dian)(dian)池(chi)(chi)拿(na)掉，然后(hou)再(zai)正常充(chong)電(dian)(dian)(dian)(dian)就可(ke)以(yi)了。

3、并聯法

這(zhe)種方法稍微麻煩一(yi)點。比如車(che)輛原(yuan)(yuan)(yuan)來是(shi)(shi)48V-20AH的(de)(de)電(dian)(dian)池，我們(men)另外并(bing)聯(lian)一(yi)組(zu)，48V-20AH的(de)(de)電(dian)(dian)池。大家(jia)知(zhi)道并(bing)聯(lian)電(dian)(dian)路各處的(de)(de)電(dian)(dian)壓(ya)是(shi)(shi)相等的(de)(de)，高的(de)(de)電(dian)(dian)壓(ya)端(duan)會向(xiang)低(di)的(de)(de)電(dian)(dian)壓(ya)端(duan)流入。這(zhe)種方法也是(shi)(shi)很多(duo)電(dian)(dian)池經銷商在檢(jian)測(ce)完全沒有(you)電(dian)(dian)的(de)(de)電(dian)(dian)池所(suo)使用(yong)的(de)(de)方法。然后進行充(chong)電(dian)(dian)也可以達到充(chong)電(dian)(dian)的(de)(de)目的(de)(de)。這(zhe)個原(yuan)(yuan)(yuan)理跟(gen)串聯(lian)一(yi)個電(dian)(dian)池原(yuan)(yuan)(yuan)理差不多(duo)，也是(shi)(shi)將整組(zu)的(de)(de)電(dian)(dian)壓(ya)提升上去。

4、低壓充電法

選用(yong)小一型號的(de)充電(dian)(dian)器進行充電(dian)(dian)。比(bi)如說(shuo)是一組60V-20AH的(de)電(dian)(dian)池，那么我們使用(yong)48V-20AH的(de)充電(dian)(dian)器進行充電(dian)(dian)。這樣大部(bu)分的(de)情(qing)況下(xia)，也是可以充進去的(de)。待(dai)電(dian)(dian)池充電(dian)(dian)最少兩小時后工作電(dian)(dian)壓升高顯著(zhu)，再換為60V-20AH的(de)充電(dian)(dian)頭做好電(dian)(dian)池充電(dian)(dian)。

5、單塊電池充電法

將(jiang)單塊電池(chi)(chi)用(yong)12伏的電動車充(chong)電器進(jin)行充(chong)電，可以(yi)將(jiang)電池(chi)(chi)激活(huo)，但這種(zhong)充(chong)電比較慢(man)，一般要充(chong)7個小時以(yi)上(shang)，電池(chi)(chi)電壓才會緩慢(man)回升(sheng)到12V左(zuo)右。如果全部(bu)單塊充(chong)很耗時間。

6、特殊充電器法

有的充(chong)電(dian)器它是(shi)自動(dong)識(shi)別電(dian)池(chi)電(dian)壓(ya)的，不管一組電(dian)池(chi)電(dian)壓(ya)有多少伏，都(dou)可以(yi)自動(dong)識(shi)別電(dian)壓(ya)，都(dou)可以(yi)充(chong)電(dian)進去。比(bi)如原車是(shi)60V-20AH的電(dian)池(chi)，現(xian)在只有30V不到，它照樣可以(yi)往里面充(chong)電(dian)的。隨著(zhu)電(dian)壓(ya)的升高，又全適(shi)應更高一階的電(dian)壓(ya)，再給電(dian)池(chi)充(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。
