一、電動車鋰電池餓死了是什么意思

電(dian)(dian)(dian)(dian)(dian)動車(che)(che)在存放(fang)(fang)(fang)過(guo)程中(zhong)，電(dian)(dian)(dian)(dian)(dian)池會有(you)自放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)的功能(neng)，如果電(dian)(dian)(dian)(dian)(dian)動車(che)(che)長時(shi)間沒有(you)騎，也沒有(you)充電(dian)(dian)(dian)(dian)(dian)，并且(qie)電(dian)(dian)(dian)(dian)(dian)動車(che)(che)坐墊底下(xia)的空氣開關也沒有(you)關，每天自放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)約有(you)0.3%～0.5%，長時(shi)間沒有(you)充電(dian)(dian)(dian)(dian)(dian)導致電(dian)(dian)(dian)(dian)(dian)動車(che)(che)持(chi)續慢性放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)，當電(dian)(dian)(dian)(dian)(dian)動車(che)(che)把(ba)電(dian)(dian)(dian)(dian)(dian)池的電(dian)(dian)(dian)(dian)(dian)完全(quan)放(fang)(fang)(fang)完了(le)，這(zhe)(zhe)時(shi)候電(dian)(dian)(dian)(dian)(dian)池就容易虧(kui)電(dian)(dian)(dian)(dian)(dian)“餓死”了(le)。電(dian)(dian)(dian)(dian)(dian)池“餓死”這(zhe)(zhe)種情況(kuang)，一般情況(kuang)下(xia)電(dian)(dian)(dian)(dian)(dian)動車(che)(che)充電(dian)(dian)(dian)(dian)(dian)器無法充電(dian)(dian)(dian)(dian)(dian)，顯示(shi)狀態(tai)為綠燈，或者不停地(di)閃爍，這(zhe)(zhe)種情況(kuang)都(dou)屬于(yu)電(dian)(dian)(dian)(dian)(dian)池餓死。

二、電動車鋰電池餓死了還能激活嗎

如果不嚴重的話是可以(yi)激活的，但如果存放(fang)超過3個月以(yi)上的電瓶，一般比(bi)較難激活，超過3個月的建(jian)議重新購買新電池(chi)來解決。

三、電動車鋰電池餓死了怎么激活

下面介(jie)紹六種(zhong)比較好的(de)方法(fa)，能將大部分(fen)的(de)這種(zhong)“餓死”的(de)電瓶拯救過來。注意是(shi)大部分(fen)不(bu)是(shi)百分(fen)百。

1、開大燈充電

首先打(da)開(kai)電門鑰匙，再開(kai)大(da)(da)燈(deng)(deng)，開(kai)大(da)(da)燈(deng)(deng)讓(rang)大(da)(da)燈(deng)(deng)亮4-5個(ge)(ge)小時，這樣也(ye)可以(yi)(yi)激活電池(chi)，堅持激活以(yi)(yi)后，把(ba)大(da)(da)燈(deng)(deng)關(guan)掉，然后顯示正(zheng)常(chang)充(chong)(chong)電，可以(yi)(yi)繼(ji)續(xu)充(chong)(chong)電池(chi)充(chong)(chong)滿為止，如(ru)果大(da)(da)燈(deng)(deng)關(guan)掉以(yi)(yi)后這個(ge)(ge)充(chong)(chong)電器(qi)還是閃爍，那繼(ji)續(xu)把(ba)這個(ge)(ge)大(da)(da)燈(deng)(deng)打(da)開(kai)繼(ji)續(xu)充(chong)(chong)，我們充(chong)(chong)到(dao)什么(me)時候？大(da)(da)燈(deng)(deng)關(guan)掉，充(chong)(chong)電器(qi)上面顯示正(zheng)常(chang)就(jiu)可以(yi)(yi)了。

2、串聯法

在整組電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)上另(ling)外(wai)串聯(lian)一(yi)個正(zheng)常(chang)(chang)電(dian)(dian)(dian)(dian)壓的(de)(de)(de)12伏電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)。比如說，原車是(shi)48V-20AH的(de)(de)(de)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，那我們再(zai)另(ling)外(wai)串聯(lian)一(yi)塊12V-20AH的(de)(de)(de)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)。一(yi)塊電(dian)(dian)(dian)(dian)量充足的(de)(de)(de)12V電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)電(dian)(dian)(dian)(dian)壓有(you)13V左(zuo)右，串聯(lian)之(zhi)后能夠提升整組電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)(de)電(dian)(dian)(dian)(dian)壓，然后再(zai)用(yong)原來的(de)(de)(de)充電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)進(jin)行充電(dian)(dian)(dian)(dian)，這樣的(de)(de)(de)話(hua)是(shi)可(ke)以將電(dian)(dian)(dian)(dian)充進(jin)去(qu)的(de)(de)(de)，插(cha)上充電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)之(zhi)后，充電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)是(shi)紅燈(deng)，此時可(ke)以將電(dian)(dian)(dian)(dian)充進(jin)去(qu)。等(deng)充電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)轉為綠燈(deng)，就把那塊另(ling)外(wai)串聯(lian)上去(qu)的(de)(de)(de)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)拿掉(diao)，然后再(zai)正(zheng)常(chang)(chang)充電(dian)(dian)(dian)(dian)就可(ke)以了(le)。

3、并聯法

這種(zhong)方法(fa)稍微麻(ma)煩一(yi)點。比如車輛(liang)原來是48V-20AH的(de)(de)(de)(de)電(dian)池(chi)，我們另外并聯(lian)一(yi)組(zu)，48V-20AH的(de)(de)(de)(de)電(dian)池(chi)。大家知道并聯(lian)電(dian)路各處(chu)的(de)(de)(de)(de)電(dian)壓是相等的(de)(de)(de)(de)，高的(de)(de)(de)(de)電(dian)壓端會(hui)向低的(de)(de)(de)(de)電(dian)壓端流入(ru)。這種(zhong)方法(fa)也是很多電(dian)池(chi)經銷商在(zai)檢測完(wan)全沒有電(dian)的(de)(de)(de)(de)電(dian)池(chi)所使用的(de)(de)(de)(de)方法(fa)。然后進(jin)行充(chong)電(dian)也可以達(da)到(dao)充(chong)電(dian)的(de)(de)(de)(de)目(mu)的(de)(de)(de)(de)。這個原理跟串聯(lian)一(yi)個電(dian)池(chi)原理差不多，也是將(jiang)整組(zu)的(de)(de)(de)(de)電(dian)壓提升上去。

4、低壓充電法

選用(yong)小一型號(hao)的(de)充(chong)電(dian)(dian)(dian)器進行(xing)充(chong)電(dian)(dian)(dian)。比如說是(shi)一組60V-20AH的(de)電(dian)(dian)(dian)池(chi)(chi)，那(nei)么我(wo)們使用(yong)48V-20AH的(de)充(chong)電(dian)(dian)(dian)器進行(xing)充(chong)電(dian)(dian)(dian)。這(zhe)樣大(da)部分的(de)情況(kuang)下，也是(shi)可(ke)以(yi)充(chong)進去的(de)。待電(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)最少兩小時后(hou)工(gong)作電(dian)(dian)(dian)壓升(sheng)高顯著，再換為60V-20AH的(de)充(chong)電(dian)(dian)(dian)頭(tou)做好電(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)。

5、單塊電池充電法

將(jiang)單(dan)塊(kuai)電(dian)(dian)(dian)池(chi)用12伏的電(dian)(dian)(dian)動(dong)車充電(dian)(dian)(dian)器進行充電(dian)(dian)(dian)，可以將(jiang)電(dian)(dian)(dian)池(chi)激活(huo)，但這種充電(dian)(dian)(dian)比較慢，一般要充7個小時以上，電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)壓才會(hui)緩慢回升(sheng)到12V左右。如(ru)果全(quan)部單(dan)塊(kuai)充很耗時間。

6、特殊充電器法

有的(de)(de)充(chong)電(dian)(dian)(dian)器它(ta)是自動(dong)識(shi)別電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)壓(ya)的(de)(de)，不管一組電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)壓(ya)有多少(shao)伏(fu)，都可(ke)以(yi)(yi)自動(dong)識(shi)別電(dian)(dian)(dian)壓(ya)，都可(ke)以(yi)(yi)充(chong)電(dian)(dian)(dian)進去。比如原車是60V-20AH的(de)(de)電(dian)(dian)(dian)池(chi)，現(xian)在只有30V不到，它(ta)照樣可(ke)以(yi)(yi)往(wang)里(li)面充(chong)電(dian)(dian)(dian)的(de)(de)。隨(sui)著電(dian)(dian)(dian)壓(ya)的(de)(de)升高，又全適(shi)應更高一階的(de)(de)電(dian)(dian)(dian)壓(ya)，再給電(dian)(dian)(dian)池(chi)充(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(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。
