一、電動車鋰電池餓死了是什么意思

電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動車在存放(fang)(fang)過程(cheng)中，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)會有自放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)功能，如果電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動車長時間(jian)沒(mei)(mei)有騎，也沒(mei)(mei)有充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，并且(qie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動車坐墊(dian)底下的(de)空氣開關也沒(mei)(mei)有關，每天自放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)約有0.3%～0.5%，長時間(jian)沒(mei)(mei)有充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)導致電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動車持續(xu)慢性放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，當電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動車把電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)完(wan)全(quan)放(fang)(fang)完(wan)了(le)，這(zhe)時候電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)就容易虧電(dian)(dian)(dian)(dian)(dian)(dian)(dian)“餓死(si)(si)”了(le)。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)“餓死(si)(si)”這(zhe)種(zhong)情(qing)況，一般情(qing)況下電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動車充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器無法充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，顯(xian)示狀態為綠燈(deng)，或者(zhe)不(bu)停(ting)地閃爍(shuo)，這(zhe)種(zhong)情(qing)況都屬于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)餓死(si)(si)。

二、電動車鋰電池餓死了還能激活嗎

如果不嚴重的話(hua)是可以(yi)激活(huo)的，但如果存放超過3個月以(yi)上的電(dian)瓶(ping)，一般(ban)比較(jiao)難激活(huo)，超過3個月的建議(yi)重新購(gou)買新電(dian)池來(lai)解決(jue)。

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(bi)較好的方法，能將大部(bu)分的這種(zhong)(zhong)“餓(e)死”的電瓶拯救(jiu)過來。注意是大部(bu)分不(bu)是百分百。

1、開大燈充電

首先打開電(dian)門鑰匙(chi)，再(zai)開大(da)燈(deng)(deng)，開大(da)燈(deng)(deng)讓大(da)燈(deng)(deng)亮(liang)4-5個小時(shi)，這樣(yang)也(ye)可以激(ji)活(huo)電(dian)池，堅持激(ji)活(huo)以后(hou)(hou)，把大(da)燈(deng)(deng)關(guan)掉(diao)，然后(hou)(hou)顯示(shi)正常充(chong)(chong)(chong)電(dian)，可以繼續(xu)充(chong)(chong)(chong)電(dian)池充(chong)(chong)(chong)滿為止(zhi)，如果大(da)燈(deng)(deng)關(guan)掉(diao)以后(hou)(hou)這個充(chong)(chong)(chong)電(dian)器(qi)還是閃爍(shuo)，那(nei)繼續(xu)把這個大(da)燈(deng)(deng)打開繼續(xu)充(chong)(chong)(chong)，我們(men)充(chong)(chong)(chong)到(dao)什么(me)時(shi)候(hou)？大(da)燈(deng)(deng)關(guan)掉(diao)，充(chong)(chong)(chong)電(dian)器(qi)上面顯示(shi)正常就可以了。

2、串聯法

在整(zheng)組電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)上另(ling)外(wai)串聯一(yi)(yi)個(ge)正(zheng)常(chang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓的(de)(de)12伏電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)。比如(ru)說(shuo)，原(yuan)(yuan)車是48V-20AH的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，那我們再(zai)另(ling)外(wai)串聯一(yi)(yi)塊(kuai)12V-20AH的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)。一(yi)(yi)塊(kuai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量充(chong)足的(de)(de)12V電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓有13V左右，串聯之(zhi)后(hou)能夠提升整(zheng)組電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓，然后(hou)再(zai)用原(yuan)(yuan)來的(de)(de)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)進行充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，這樣的(de)(de)話是可(ke)以(yi)將(jiang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)充(chong)進去的(de)(de)，插上充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)之(zhi)后(hou)，充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)是紅燈，此(ci)時可(ke)以(yi)將(jiang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)充(chong)進去。等充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)轉(zhuan)為(wei)綠燈，就(jiu)(jiu)把那塊(kuai)另(ling)外(wai)串聯上去的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)拿(na)掉，然后(hou)再(zai)正(zheng)常(chang)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)就(jiu)(jiu)可(ke)以(yi)了。

3、并聯法

這種方(fang)法(fa)稍(shao)微麻煩一點。比(bi)如車輛原來是48V-20AH的電(dian)(dian)(dian)(dian)池，我們另(ling)外并(bing)聯(lian)一組，48V-20AH的電(dian)(dian)(dian)(dian)池。大(da)家(jia)知道并(bing)聯(lian)電(dian)(dian)(dian)(dian)路各處的電(dian)(dian)(dian)(dian)壓是相等的，高的電(dian)(dian)(dian)(dian)壓端會向低(di)的電(dian)(dian)(dian)(dian)壓端流入。這種方(fang)法(fa)也是很多(duo)電(dian)(dian)(dian)(dian)池經銷商(shang)在檢測完全沒(mei)有電(dian)(dian)(dian)(dian)的電(dian)(dian)(dian)(dian)池所使用的方(fang)法(fa)。然后進行充(chong)電(dian)(dian)(dian)(dian)也可以達到充(chong)電(dian)(dian)(dian)(dian)的目(mu)的。這個(ge)原理跟串聯(lian)一個(ge)電(dian)(dian)(dian)(dian)池原理差不多(duo)，也是將整組的電(dian)(dian)(dian)(dian)壓提(ti)升上(shang)去(qu)。

4、低壓充電法

選用小一型號(hao)的(de)充(chong)(chong)電(dian)器(qi)進行充(chong)(chong)電(dian)。比如說(shuo)是(shi)一組60V-20AH的(de)電(dian)池，那(nei)么(me)我們使用48V-20AH的(de)充(chong)(chong)電(dian)器(qi)進行充(chong)(chong)電(dian)。這樣大部(bu)分的(de)情況下，也是(shi)可以充(chong)(chong)進去(qu)的(de)。待(dai)電(dian)池充(chong)(chong)電(dian)最少兩小時后工(gong)作電(dian)壓升高顯著，再換為60V-20AH的(de)充(chong)(chong)電(dian)頭做(zuo)好電(dian)池充(chong)(chong)電(dian)。

5、單塊電池充電法

將(jiang)單(dan)塊電(dian)(dian)池用12伏的(de)電(dian)(dian)動車充電(dian)(dian)器進行充電(dian)(dian)，可(ke)以將(jiang)電(dian)(dian)池激活(huo)，但這(zhe)種充電(dian)(dian)比(bi)較(jiao)慢，一般要充7個小時以上，電(dian)(dian)池電(dian)(dian)壓(ya)才會緩慢回升到(dao)12V左(zuo)右。如果全部單(dan)塊充很耗時間(jian)。

6、特殊充電器法

有的(de)(de)充電(dian)(dian)器它是(shi)自動識(shi)別電(dian)(dian)池電(dian)(dian)壓(ya)(ya)的(de)(de)，不管(guan)一組電(dian)(dian)池電(dian)(dian)壓(ya)(ya)有多少伏，都(dou)可以(yi)(yi)自動識(shi)別電(dian)(dian)壓(ya)(ya)，都(dou)可以(yi)(yi)充電(dian)(dian)進去(qu)。比如原(yuan)車是(shi)60V-20AH的(de)(de)電(dian)(dian)池，現在只(zhi)有30V不到，它照樣可以(yi)(yi)往里面充電(dian)(dian)的(de)(de)。隨著電(dian)(dian)壓(ya)(ya)的(de)(de)升(sheng)高(gao)，又全適應更高(gao)一階的(de)(de)電(dian)(dian)壓(ya)(ya)，再給電(dian)(dian)池充電(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(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。
