一、電動車鋰電池餓死了是什么意思

電(dian)(dian)(dian)動車在(zai)存放(fang)(fang)過程中，電(dian)(dian)(dian)池(chi)會有(you)(you)(you)自放(fang)(fang)電(dian)(dian)(dian)的(de)功能，如果電(dian)(dian)(dian)動車長(chang)時間沒有(you)(you)(you)騎，也(ye)沒有(you)(you)(you)充(chong)(chong)電(dian)(dian)(dian)，并且電(dian)(dian)(dian)動車坐墊底下(xia)的(de)空氣開關也(ye)沒有(you)(you)(you)關，每天自放(fang)(fang)電(dian)(dian)(dian)約有(you)(you)(you)0.3%～0.5%，長(chang)時間沒有(you)(you)(you)充(chong)(chong)電(dian)(dian)(dian)導(dao)致電(dian)(dian)(dian)動車持(chi)續慢性放(fang)(fang)電(dian)(dian)(dian)，當(dang)電(dian)(dian)(dian)動車把(ba)電(dian)(dian)(dian)池(chi)的(de)電(dian)(dian)(dian)完全(quan)放(fang)(fang)完了，這時候電(dian)(dian)(dian)池(chi)就容(rong)易虧電(dian)(dian)(dian)“餓(e)死”了。電(dian)(dian)(dian)池(chi)“餓(e)死”這種情況，一(yi)般(ban)情況下(xia)電(dian)(dian)(dian)動車充(chong)(chong)電(dian)(dian)(dian)器無法(fa)充(chong)(chong)電(dian)(dian)(dian)，顯示狀態為(wei)綠燈，或者不停(ting)地(di)閃爍(shuo)，這種情況都屬于電(dian)(dian)(dian)池(chi)餓(e)死。

二、電動車鋰電池餓死了還能激活嗎

如果(guo)不(bu)嚴重的話是可以激活的，但如果(guo)存放超過3個月以上(shang)的電瓶，一般(ban)比較難激活，超過3個月的建議重新購(gou)買新電池(chi)來解決。

三、電動車鋰電池餓死了怎么激活

下(xia)面介紹六種(zhong)(zhong)比較好的(de)方法，能將大部分的(de)這種(zhong)(zhong)“餓(e)死”的(de)電瓶(ping)拯救過來。注(zhu)意(yi)是(shi)大部分不是(shi)百分百。

1、開大燈充電

首先(xian)打開電(dian)門鑰(yao)匙，再開大(da)燈，開大(da)燈讓大(da)燈亮4-5個(ge)小時(shi)，這樣也(ye)可(ke)以(yi)(yi)激活(huo)電(dian)池(chi)(chi)，堅持(chi)激活(huo)以(yi)(yi)后，把大(da)燈關(guan)掉，然(ran)后顯(xian)示(shi)正常充(chong)(chong)電(dian)，可(ke)以(yi)(yi)繼(ji)續充(chong)(chong)電(dian)池(chi)(chi)充(chong)(chong)滿為(wei)止，如果大(da)燈關(guan)掉以(yi)(yi)后這個(ge)充(chong)(chong)電(dian)器還是(shi)閃爍，那(nei)繼(ji)續把這個(ge)大(da)燈打開繼(ji)續充(chong)(chong)，我(wo)們充(chong)(chong)到什么時(shi)候？大(da)燈關(guan)掉，充(chong)(chong)電(dian)器上面顯(xian)示(shi)正常就可(ke)以(yi)(yi)了(le)。

2、串聯法

在(zai)整(zheng)組(zu)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)上(shang)另(ling)外(wai)串(chuan)聯(lian)(lian)一個正常(chang)電(dian)(dian)(dian)壓的(de)(de)(de)12伏電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)。比(bi)如說(shuo)，原車是(shi)48V-20AH的(de)(de)(de)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，那我們(men)再另(ling)外(wai)串(chuan)聯(lian)(lian)一塊12V-20AH的(de)(de)(de)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)。一塊電(dian)(dian)(dian)量充(chong)(chong)(chong)足的(de)(de)(de)12V電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)電(dian)(dian)(dian)壓有13V左右，串(chuan)聯(lian)(lian)之(zhi)后能夠提升整(zheng)組(zu)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)(de)電(dian)(dian)(dian)壓，然(ran)后再用原來的(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)進(jin)行(xing)充(chong)(chong)(chong)電(dian)(dian)(dian)，這(zhe)樣的(de)(de)(de)話是(shi)可以將電(dian)(dian)(dian)充(chong)(chong)(chong)進(jin)去(qu)的(de)(de)(de)，插上(shang)充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)之(zhi)后，充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)是(shi)紅燈，此時可以將電(dian)(dian)(dian)充(chong)(chong)(chong)進(jin)去(qu)。等充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)轉為綠(lv)燈，就(jiu)把那塊另(ling)外(wai)串(chuan)聯(lian)(lian)上(shang)去(qu)的(de)(de)(de)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)拿掉，然(ran)后再正常(chang)充(chong)(chong)(chong)電(dian)(dian)(dian)就(jiu)可以了。

3、并聯法

這種方(fang)(fang)法稍微麻煩一點。比如車輛原(yuan)來是(shi)48V-20AH的電(dian)(dian)(dian)(dian)(dian)池(chi)，我們另外并聯一組，48V-20AH的電(dian)(dian)(dian)(dian)(dian)池(chi)。大家知(zhi)道并聯電(dian)(dian)(dian)(dian)(dian)路各處的電(dian)(dian)(dian)(dian)(dian)壓(ya)是(shi)相等的，高的電(dian)(dian)(dian)(dian)(dian)壓(ya)端會(hui)向低的電(dian)(dian)(dian)(dian)(dian)壓(ya)端流(liu)入。這種方(fang)(fang)法也是(shi)很多電(dian)(dian)(dian)(dian)(dian)池(chi)經(jing)銷(xiao)商在檢測完全沒(mei)有電(dian)(dian)(dian)(dian)(dian)的電(dian)(dian)(dian)(dian)(dian)池(chi)所使(shi)用的方(fang)(fang)法。然(ran)后進行(xing)充(chong)電(dian)(dian)(dian)(dian)(dian)也可以(yi)達到充(chong)電(dian)(dian)(dian)(dian)(dian)的目的。這個(ge)原(yuan)理跟串聯一個(ge)電(dian)(dian)(dian)(dian)(dian)池(chi)原(yuan)理差不多，也是(shi)將整組的電(dian)(dian)(dian)(dian)(dian)壓(ya)提升上去(qu)。

4、低壓充電法

選用(yong)小一型號(hao)的充(chong)電(dian)(dian)器(qi)(qi)進(jin)行(xing)充(chong)電(dian)(dian)。比如(ru)說是一組60V-20AH的電(dian)(dian)池，那么我們使用(yong)48V-20AH的充(chong)電(dian)(dian)器(qi)(qi)進(jin)行(xing)充(chong)電(dian)(dian)。這(zhe)樣(yang)大部分的情況下，也是可(ke)以(yi)充(chong)進(jin)去的。待電(dian)(dian)池充(chong)電(dian)(dian)最(zui)少兩小時(shi)后工作電(dian)(dian)壓升高顯著，再換(huan)為60V-20AH的充(chong)電(dian)(dian)頭做(zuo)好電(dian)(dian)池充(chong)電(dian)(dian)。

5、單塊電池充電法

將單(dan)塊(kuai)電(dian)(dian)池用(yong)12伏的電(dian)(dian)動車充電(dian)(dian)器進行充電(dian)(dian)，可以(yi)將電(dian)(dian)池激(ji)活(huo)，但這種充電(dian)(dian)比(bi)較慢，一(yi)般要充7個小時(shi)以(yi)上，電(dian)(dian)池電(dian)(dian)壓才會(hui)緩慢回(hui)升(sheng)到12V左(zuo)右。如果全部單(dan)塊(kuai)充很耗時(shi)間。

6、特殊充電器法

有的(de)充(chong)(chong)電(dian)(dian)(dian)器它是自動識別(bie)電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)壓(ya)的(de)，不(bu)管一組電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)壓(ya)有多少伏，都(dou)可以(yi)(yi)自動識別(bie)電(dian)(dian)(dian)壓(ya)，都(dou)可以(yi)(yi)充(chong)(chong)電(dian)(dian)(dian)進去(qu)。比(bi)如原車是60V-20AH的(de)電(dian)(dian)(dian)池(chi)，現在(zai)只有30V不(bu)到，它照樣可以(yi)(yi)往里(li)面充(chong)(chong)電(dian)(dian)(dian)的(de)。隨著(zhu)電(dian)(dian)(dian)壓(ya)的(de)升(sheng)高，又全(quan)適應更高一階的(de)電(dian)(dian)(dian)壓(ya)，再給電(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。
