一、電動車鋰電池餓死了是什么意思

電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)車(che)在存放過程中，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池會有(you)自放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的功能，如果電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)車(che)長時間沒有(you)騎(qi)，也沒有(you)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，并且電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)車(che)坐墊(dian)底下的空氣開關也沒有(you)關，每天自放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)約有(you)0.3%～0.5%，長時間沒有(you)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)導致電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)車(che)持續慢性放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，當電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)車(che)把電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)完(wan)(wan)全放完(wan)(wan)了，這(zhe)時候電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池就容易虧(kui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)“餓死”了。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池“餓死”這(zhe)種情況，一(yi)般情況下電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)車(che)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)無法充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，顯示狀(zhuang)態為綠(lv)燈，或(huo)者(zhe)不停地閃爍，這(zhe)種情況都屬于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池餓死。

二、電動車鋰電池餓死了還能激活嗎

如(ru)果(guo)不(bu)嚴重的(de)(de)話是可以激(ji)活的(de)(de)，但如(ru)果(guo)存放(fang)超(chao)過3個月以上的(de)(de)電瓶，一般比較難(nan)激(ji)活，超(chao)過3個月的(de)(de)建議重新(xin)購買新(xin)電池來解(jie)決。

三、電動車鋰電池餓死了怎么激活

下面介(jie)紹六(liu)種(zhong)(zhong)比較好的方(fang)法(fa)，能將(jiang)大部分的這種(zhong)(zhong)“餓(e)死”的電瓶拯救過來。注意是(shi)大部分不是(shi)百(bai)分百(bai)。

1、開大燈充電

首先打(da)開電(dian)門鑰匙，再開大(da)(da)(da)燈(deng)，開大(da)(da)(da)燈(deng)讓(rang)大(da)(da)(da)燈(deng)亮4-5個小時，這(zhe)樣也可(ke)以激(ji)(ji)活電(dian)池(chi)，堅持激(ji)(ji)活以后，把(ba)大(da)(da)(da)燈(deng)關(guan)掉(diao)(diao)，然后顯示(shi)正(zheng)常充電(dian)，可(ke)以繼續(xu)充電(dian)池(chi)充滿為(wei)止，如果大(da)(da)(da)燈(deng)關(guan)掉(diao)(diao)以后這(zhe)個充電(dian)器還是閃爍(shuo)，那繼續(xu)把(ba)這(zhe)個大(da)(da)(da)燈(deng)打(da)開繼續(xu)充，我們充到(dao)什么時候？大(da)(da)(da)燈(deng)關(guan)掉(diao)(diao)，充電(dian)器上(shang)面顯示(shi)正(zheng)常就可(ke)以了。

2、串聯法

在整組電(dian)(dian)(dian)池(chi)上(shang)(shang)另外(wai)(wai)(wai)串(chuan)(chuan)聯(lian)(lian)一(yi)個正常(chang)電(dian)(dian)(dian)壓的(de)12伏電(dian)(dian)(dian)池(chi)。比如說，原車(che)是48V-20AH的(de)電(dian)(dian)(dian)池(chi)，那我們再(zai)另外(wai)(wai)(wai)串(chuan)(chuan)聯(lian)(lian)一(yi)塊(kuai)(kuai)12V-20AH的(de)電(dian)(dian)(dian)池(chi)。一(yi)塊(kuai)(kuai)電(dian)(dian)(dian)量充(chong)(chong)(chong)足的(de)12V電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)壓有13V左右，串(chuan)(chuan)聯(lian)(lian)之后能(neng)夠提升整組電(dian)(dian)(dian)池(chi)的(de)電(dian)(dian)(dian)壓，然后再(zai)用原來的(de)充(chong)(chong)(chong)電(dian)(dian)(dian)器進(jin)行(xing)充(chong)(chong)(chong)電(dian)(dian)(dian)，這樣的(de)話是可(ke)以(yi)將電(dian)(dian)(dian)充(chong)(chong)(chong)進(jin)去的(de)，插上(shang)(shang)充(chong)(chong)(chong)電(dian)(dian)(dian)器之后，充(chong)(chong)(chong)電(dian)(dian)(dian)器是紅燈(deng)，此時可(ke)以(yi)將電(dian)(dian)(dian)充(chong)(chong)(chong)進(jin)去。等充(chong)(chong)(chong)電(dian)(dian)(dian)器轉為(wei)綠燈(deng)，就(jiu)把(ba)那塊(kuai)(kuai)另外(wai)(wai)(wai)串(chuan)(chuan)聯(lian)(lian)上(shang)(shang)去的(de)電(dian)(dian)(dian)池(chi)拿掉(diao)，然后再(zai)正常(chang)充(chong)(chong)(chong)電(dian)(dian)(dian)就(jiu)可(ke)以(yi)了。

3、并聯法

這種方法稍(shao)微麻煩一點。比如車(che)輛原(yuan)(yuan)來是48V-20AH的電(dian)池(chi)，我們另外并聯(lian)一組，48V-20AH的電(dian)池(chi)。大家知道并聯(lian)電(dian)路各處的電(dian)壓是相等的，高的電(dian)壓端(duan)會向(xiang)低的電(dian)壓端(duan)流入。這種方法也(ye)(ye)是很(hen)多(duo)電(dian)池(chi)經銷(xiao)商在(zai)檢測完(wan)全沒(mei)有電(dian)的電(dian)池(chi)所使用的方法。然后進行充電(dian)也(ye)(ye)可以達(da)到充電(dian)的目的。這個(ge)(ge)原(yuan)(yuan)理跟串聯(lian)一個(ge)(ge)電(dian)池(chi)原(yuan)(yuan)理差不多(duo)，也(ye)(ye)是將整(zheng)組的電(dian)壓提升上(shang)去(qu)。

4、低壓充電法

選用小一(yi)型號的(de)充(chong)(chong)電(dian)器進(jin)(jin)行充(chong)(chong)電(dian)。比如說是(shi)一(yi)組60V-20AH的(de)電(dian)池(chi)，那么我們(men)使用48V-20AH的(de)充(chong)(chong)電(dian)器進(jin)(jin)行充(chong)(chong)電(dian)。這樣(yang)大部分的(de)情況下，也是(shi)可以(yi)充(chong)(chong)進(jin)(jin)去的(de)。待電(dian)池(chi)充(chong)(chong)電(dian)最少兩小時后工作電(dian)壓升(sheng)高顯著，再換為(wei)60V-20AH的(de)充(chong)(chong)電(dian)頭做好電(dian)池(chi)充(chong)(chong)電(dian)。

5、單塊電池充電法

將單塊電(dian)(dian)池(chi)用12伏的電(dian)(dian)動(dong)車充(chong)電(dian)(dian)器進行(xing)充(chong)電(dian)(dian)，可以將電(dian)(dian)池(chi)激活，但(dan)這種充(chong)電(dian)(dian)比(bi)較慢，一般要充(chong)7個小時(shi)以上，電(dian)(dian)池(chi)電(dian)(dian)壓才(cai)會緩慢回(hui)升到(dao)12V左右。如果全部單塊充(chong)很耗時(shi)間。

6、特殊充電器法

有(you)的充(chong)(chong)電(dian)(dian)(dian)器它是自(zi)動(dong)(dong)識別電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)壓(ya)(ya)的，不管一組(zu)電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)壓(ya)(ya)有(you)多少伏，都可(ke)以(yi)自(zi)動(dong)(dong)識別電(dian)(dian)(dian)壓(ya)(ya)，都可(ke)以(yi)充(chong)(chong)電(dian)(dian)(dian)進去。比如原車是60V-20AH的電(dian)(dian)(dian)池(chi)，現在只有(you)30V不到，它照樣可(ke)以(yi)往里面(mian)充(chong)(chong)電(dian)(dian)(dian)的。隨著電(dian)(dian)(dian)壓(ya)(ya)的升(sheng)高(gao)，又(you)全適應(ying)更高(gao)一階的電(dian)(dian)(dian)壓(ya)(ya)，再給(gei)電(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(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。
