一、電動車鋰電池餓死了是什么意思

電(dian)(dian)動(dong)(dong)車(che)在存(cun)放(fang)(fang)過程中，電(dian)(dian)池(chi)會有(you)自放(fang)(fang)電(dian)(dian)的(de)功能，如(ru)果電(dian)(dian)動(dong)(dong)車(che)長(chang)時間(jian)沒(mei)(mei)有(you)騎，也沒(mei)(mei)有(you)充(chong)電(dian)(dian)，并且電(dian)(dian)動(dong)(dong)車(che)坐墊(dian)底(di)下的(de)空氣開關也沒(mei)(mei)有(you)關，每天自放(fang)(fang)電(dian)(dian)約(yue)有(you)0.3%～0.5%，長(chang)時間(jian)沒(mei)(mei)有(you)充(chong)電(dian)(dian)導致電(dian)(dian)動(dong)(dong)車(che)持續(xu)慢性放(fang)(fang)電(dian)(dian)，當電(dian)(dian)動(dong)(dong)車(che)把電(dian)(dian)池(chi)的(de)電(dian)(dian)完全放(fang)(fang)完了，這(zhe)時候電(dian)(dian)池(chi)就容(rong)易虧電(dian)(dian)“餓死”了。電(dian)(dian)池(chi)“餓死”這(zhe)種情(qing)況，一般(ban)情(qing)況下電(dian)(dian)動(dong)(dong)車(che)充(chong)電(dian)(dian)器無(wu)法充(chong)電(dian)(dian)，顯示狀(zhuang)態為綠(lv)燈，或(huo)者不(bu)停地閃爍，這(zhe)種情(qing)況都(dou)屬(shu)于電(dian)(dian)池(chi)餓死。

二、電動車鋰電池餓死了還能激活嗎

如果不嚴重的(de)(de)(de)話(hua)是可以激活(huo)(huo)的(de)(de)(de)，但如果存(cun)放超過(guo)3個月(yue)(yue)以上的(de)(de)(de)電瓶，一般比較難激活(huo)(huo)，超過(guo)3個月(yue)(yue)的(de)(de)(de)建議重新購買新電池來解決。

三、電動車鋰電池餓死了怎么激活

下面介紹六種比較好的方法，能將(jiang)大部分的這種“餓死”的電瓶拯救過來。注意是(shi)大部分不(bu)是(shi)百分百。

1、開大燈充電

首先打(da)開(kai)電(dian)門(men)鑰匙，再開(kai)大(da)燈(deng)(deng)，開(kai)大(da)燈(deng)(deng)讓大(da)燈(deng)(deng)亮4-5個小時，這(zhe)樣也可以激(ji)活電(dian)池(chi)，堅持激(ji)活以后，把大(da)燈(deng)(deng)關(guan)(guan)掉(diao)，然后顯示正常(chang)充(chong)電(dian)，可以繼續充(chong)電(dian)池(chi)充(chong)滿(man)為(wei)止，如果(guo)大(da)燈(deng)(deng)關(guan)(guan)掉(diao)以后這(zhe)個充(chong)電(dian)器(qi)還(huan)是閃爍，那繼續把這(zhe)個大(da)燈(deng)(deng)打(da)開(kai)繼續充(chong)，我們(men)充(chong)到什么(me)時候？大(da)燈(deng)(deng)關(guan)(guan)掉(diao)，充(chong)電(dian)器(qi)上面(mian)顯示正常(chang)就可以了。

2、串聯法

在整(zheng)組(zu)電(dian)(dian)(dian)(dian)池(chi)(chi)上(shang)另(ling)外(wai)串聯(lian)一個正常電(dian)(dian)(dian)(dian)壓的(de)12伏電(dian)(dian)(dian)(dian)池(chi)(chi)。比如說，原(yuan)車是(shi)48V-20AH的(de)電(dian)(dian)(dian)(dian)池(chi)(chi)，那(nei)我(wo)們再另(ling)外(wai)串聯(lian)一塊12V-20AH的(de)電(dian)(dian)(dian)(dian)池(chi)(chi)。一塊電(dian)(dian)(dian)(dian)量充足的(de)12V電(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)壓有13V左右，串聯(lian)之后能夠提升整(zheng)組(zu)電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)電(dian)(dian)(dian)(dian)壓，然(ran)后再用原(yuan)來的(de)充電(dian)(dian)(dian)(dian)器(qi)進(jin)(jin)行(xing)充電(dian)(dian)(dian)(dian)，這(zhe)樣的(de)話是(shi)可以(yi)將(jiang)電(dian)(dian)(dian)(dian)充進(jin)(jin)去(qu)的(de)，插上(shang)充電(dian)(dian)(dian)(dian)器(qi)之后，充電(dian)(dian)(dian)(dian)器(qi)是(shi)紅(hong)燈(deng)，此時可以(yi)將(jiang)電(dian)(dian)(dian)(dian)充進(jin)(jin)去(qu)。等充電(dian)(dian)(dian)(dian)器(qi)轉為綠(lv)燈(deng)，就把那(nei)塊另(ling)外(wai)串聯(lian)上(shang)去(qu)的(de)電(dian)(dian)(dian)(dian)池(chi)(chi)拿掉，然(ran)后再正常充電(dian)(dian)(dian)(dian)就可以(yi)了。

3、并聯法

這種方(fang)法稍微麻煩一(yi)點。比(bi)如車輛原來是48V-20AH的(de)(de)(de)電(dian)(dian)(dian)(dian)池，我們(men)另外并(bing)聯一(yi)組，48V-20AH的(de)(de)(de)電(dian)(dian)(dian)(dian)池。大家知道并(bing)聯電(dian)(dian)(dian)(dian)路各處的(de)(de)(de)電(dian)(dian)(dian)(dian)壓(ya)是相等的(de)(de)(de)，高的(de)(de)(de)電(dian)(dian)(dian)(dian)壓(ya)端會向低的(de)(de)(de)電(dian)(dian)(dian)(dian)壓(ya)端流入。這種方(fang)法也是很多電(dian)(dian)(dian)(dian)池經銷商在檢(jian)測完全沒(mei)有電(dian)(dian)(dian)(dian)的(de)(de)(de)電(dian)(dian)(dian)(dian)池所(suo)使(shi)用的(de)(de)(de)方(fang)法。然(ran)后進行充(chong)電(dian)(dian)(dian)(dian)也可以達到充(chong)電(dian)(dian)(dian)(dian)的(de)(de)(de)目的(de)(de)(de)。這個原理跟串聯一(yi)個電(dian)(dian)(dian)(dian)池原理差不多，也是將(jiang)整組的(de)(de)(de)電(dian)(dian)(dian)(dian)壓(ya)提升上去(qu)。

4、低壓充電法

選(xuan)用小(xiao)一型號(hao)的(de)(de)充電(dian)(dian)器(qi)進行充電(dian)(dian)。比如說是一組(zu)60V-20AH的(de)(de)電(dian)(dian)池，那么我們(men)使用48V-20AH的(de)(de)充電(dian)(dian)器(qi)進行充電(dian)(dian)。這樣大部分(fen)的(de)(de)情況下，也(ye)是可以充進去的(de)(de)。待電(dian)(dian)池充電(dian)(dian)最少(shao)兩小(xiao)時后工作電(dian)(dian)壓升高顯著，再換為60V-20AH的(de)(de)充電(dian)(dian)頭做好電(dian)(dian)池充電(dian)(dian)。

5、單塊電池充電法

將單塊電(dian)(dian)池用12伏(fu)的(de)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)池激活(huo)，但這(zhe)種充(chong)電(dian)(dian)比較慢，一(yi)般要充(chong)7個小時以上，電(dian)(dian)池電(dian)(dian)壓才會(hui)緩慢回(hui)升到(dao)12V左(zuo)右(you)。如果全(quan)部(bu)單塊充(chong)很耗時間(jian)。

6、特殊充電器法

有的(de)(de)充電(dian)(dian)器(qi)它是自動識別電(dian)(dian)池(chi)電(dian)(dian)壓(ya)的(de)(de)，不(bu)管(guan)一組電(dian)(dian)池(chi)電(dian)(dian)壓(ya)有多(duo)少伏，都(dou)可以自動識別電(dian)(dian)壓(ya)，都(dou)可以充電(dian)(dian)進去。比如(ru)原車是60V-20AH的(de)(de)電(dian)(dian)池(chi)，現在(zai)只有30V不(bu)到，它照樣可以往里面充電(dian)(dian)的(de)(de)。隨(sui)著電(dian)(dian)壓(ya)的(de)(de)升(sheng)高(gao)，又全適應更(geng)高(gao)一階的(de)(de)電(dian)(dian)壓(ya)，再(zai)給電(dian)(dian)池(chi)充電(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。
