一、電動車鋰電池餓死了是什么意思

電(dian)(dian)(dian)動(dong)(dong)車在存放過程(cheng)中，電(dian)(dian)(dian)池(chi)(chi)會有(you)自(zi)放電(dian)(dian)(dian)的功能，如(ru)果電(dian)(dian)(dian)動(dong)(dong)車長時(shi)(shi)間沒(mei)有(you)騎，也沒(mei)有(you)充(chong)電(dian)(dian)(dian)，并且電(dian)(dian)(dian)動(dong)(dong)車坐墊(dian)底下(xia)的空(kong)氣開關(guan)也沒(mei)有(you)關(guan)，每天自(zi)放電(dian)(dian)(dian)約有(you)0.3%～0.5%，長時(shi)(shi)間沒(mei)有(you)充(chong)電(dian)(dian)(dian)導致電(dian)(dian)(dian)動(dong)(dong)車持續慢性放電(dian)(dian)(dian)，當電(dian)(dian)(dian)動(dong)(dong)車把電(dian)(dian)(dian)池(chi)(chi)的電(dian)(dian)(dian)完全放完了(le)，這(zhe)時(shi)(shi)候(hou)電(dian)(dian)(dian)池(chi)(chi)就容易虧電(dian)(dian)(dian)“餓死(si)”了(le)。電(dian)(dian)(dian)池(chi)(chi)“餓死(si)”這(zhe)種(zhong)情(qing)況(kuang)，一般情(qing)況(kuang)下(xia)電(dian)(dian)(dian)動(dong)(dong)車充(chong)電(dian)(dian)(dian)器無法充(chong)電(dian)(dian)(dian)，顯示狀(zhuang)態為綠燈，或者不(bu)停地閃爍，這(zhe)種(zhong)情(qing)況(kuang)都屬于電(dian)(dian)(dian)池(chi)(chi)餓死(si)。

二、電動車鋰電池餓死了還能激活嗎

如果(guo)不嚴重的話是可以(yi)激活(huo)的，但(dan)如果(guo)存放超(chao)過3個月以(yi)上(shang)的電(dian)瓶，一般比較難激活(huo)，超(chao)過3個月的建議重新(xin)購買(mai)新(xin)電(dian)池來(lai)解決。

三、電動車鋰電池餓死了怎么激活

下(xia)面(mian)介(jie)紹(shao)六種比較好的(de)方法，能將大部分(fen)的(de)這種“餓死”的(de)電瓶拯救過來。注意是大部分(fen)不是百分(fen)百。

1、開大燈充電

首(shou)先打開電門(men)鑰(yao)匙，再開大(da)(da)燈(deng)，開大(da)(da)燈(deng)讓大(da)(da)燈(deng)亮4-5個小時，這(zhe)樣(yang)也可(ke)以(yi)激活(huo)電池(chi)，堅持(chi)激活(huo)以(yi)后(hou)(hou)，把大(da)(da)燈(deng)關(guan)掉，然后(hou)(hou)顯示(shi)正常充(chong)電，可(ke)以(yi)繼續(xu)充(chong)電池(chi)充(chong)滿為止，如果大(da)(da)燈(deng)關(guan)掉以(yi)后(hou)(hou)這(zhe)個充(chong)電器還(huan)是閃爍，那繼續(xu)把這(zhe)個大(da)(da)燈(deng)打開繼續(xu)充(chong)，我們(men)充(chong)到什(shen)么時候(hou)？大(da)(da)燈(deng)關(guan)掉，充(chong)電器上面顯示(shi)正常就可(ke)以(yi)了(le)。

2、串聯法

在整組電(dian)(dian)池(chi)上另外串聯(lian)一個正(zheng)常(chang)(chang)電(dian)(dian)壓的(de)12伏電(dian)(dian)池(chi)。比如說，原車(che)是48V-20AH的(de)電(dian)(dian)池(chi)，那(nei)我們再(zai)另外串聯(lian)一塊(kuai)(kuai)12V-20AH的(de)電(dian)(dian)池(chi)。一塊(kuai)(kuai)電(dian)(dian)量充足的(de)12V電(dian)(dian)池(chi)電(dian)(dian)壓有13V左(zuo)右，串聯(lian)之后(hou)能夠提升整組電(dian)(dian)池(chi)的(de)電(dian)(dian)壓，然后(hou)再(zai)用原來(lai)的(de)充電(dian)(dian)器(qi)進(jin)行充電(dian)(dian)，這樣的(de)話是可以將電(dian)(dian)充進(jin)去(qu)的(de)，插上充電(dian)(dian)器(qi)之后(hou)，充電(dian)(dian)器(qi)是紅燈(deng)(deng)，此時可以將電(dian)(dian)充進(jin)去(qu)。等(deng)充電(dian)(dian)器(qi)轉(zhuan)為(wei)綠(lv)燈(deng)(deng)，就把那(nei)塊(kuai)(kuai)另外串聯(lian)上去(qu)的(de)電(dian)(dian)池(chi)拿掉，然后(hou)再(zai)正(zheng)常(chang)(chang)充電(dian)(dian)就可以了。

3、并聯法

這種方(fang)法(fa)稍微麻煩一(yi)點。比(bi)如車輛原(yuan)來是48V-20AH的(de)(de)電(dian)(dian)(dian)池，我們另外并聯(lian)一(yi)組，48V-20AH的(de)(de)電(dian)(dian)(dian)池。大家知道并聯(lian)電(dian)(dian)(dian)路各處的(de)(de)電(dian)(dian)(dian)壓(ya)是相等的(de)(de)，高的(de)(de)電(dian)(dian)(dian)壓(ya)端(duan)會向(xiang)低的(de)(de)電(dian)(dian)(dian)壓(ya)端(duan)流入。這種方(fang)法(fa)也是很多電(dian)(dian)(dian)池經銷商在檢測完全沒有電(dian)(dian)(dian)的(de)(de)電(dian)(dian)(dian)池所使用的(de)(de)方(fang)法(fa)。然后進行充電(dian)(dian)(dian)也可以達到充電(dian)(dian)(dian)的(de)(de)目的(de)(de)。這個原(yuan)理跟串聯(lian)一(yi)個電(dian)(dian)(dian)池原(yuan)理差不多，也是將整組的(de)(de)電(dian)(dian)(dian)壓(ya)提(ti)升(sheng)上去(qu)。

4、低壓充電法

選用小(xiao)(xiao)一(yi)型號的充(chong)(chong)(chong)電(dian)(dian)器(qi)進(jin)行充(chong)(chong)(chong)電(dian)(dian)。比如(ru)說是一(yi)組60V-20AH的電(dian)(dian)池，那么我(wo)們(men)使用48V-20AH的充(chong)(chong)(chong)電(dian)(dian)器(qi)進(jin)行充(chong)(chong)(chong)電(dian)(dian)。這(zhe)樣大部分的情況下，也是可(ke)以充(chong)(chong)(chong)進(jin)去(qu)的。待(dai)電(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)最少兩小(xiao)(xiao)時(shi)后(hou)工作(zuo)電(dian)(dian)壓升(sheng)高顯著，再換為(wei)60V-20AH的充(chong)(chong)(chong)電(dian)(dian)頭做好電(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)。

5、單塊電池充電法

將(jiang)單(dan)塊電(dian)(dian)(dian)池用12伏的電(dian)(dian)(dian)動車充(chong)電(dian)(dian)(dian)器進行充(chong)電(dian)(dian)(dian)，可以將(jiang)電(dian)(dian)(dian)池激(ji)活，但這種充(chong)電(dian)(dian)(dian)比較慢(man)，一般要充(chong)7個小時(shi)以上，電(dian)(dian)(dian)池電(dian)(dian)(dian)壓(ya)才(cai)會緩慢(man)回升到12V左右(you)。如果全部單(dan)塊充(chong)很(hen)耗時(shi)間。

6、特殊充電器法

有的充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器它是自動識別電(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)壓的，不管一組電(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)壓有多少伏，都(dou)可(ke)(ke)以自動識別電(dian)(dian)(dian)(dian)(dian)壓，都(dou)可(ke)(ke)以充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)進去。比如原車是60V-20AH的電(dian)(dian)(dian)(dian)(dian)池(chi)，現在只有30V不到，它照樣可(ke)(ke)以往(wang)里面充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)的。隨著電(dian)(dian)(dian)(dian)(dian)壓的升高，又全適應更高一階的電(dian)(dian)(dian)(dian)(dian)壓，再給電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(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。
