很(hen)多(duo)人有(you)不(bu)好的(de)習慣，經(jing)常人不(bu)在(zai)家(jia)將電(dian)動車電(dian)池放(fang)車上，空氣開關也不(bu)關掉，放(fang)幾個月(yue)不(bu)騎(qi)。幾個月(yue)后(hou)再來騎(qi)行時就發現(xian)車子沒電(dian)而且充(chong)(chong)電(dian)充(chong)(chong)不(bu)進去(qu)。充(chong)(chong)電(dian)器插(cha)上去(qu)，但是(shi)一直是(shi)綠燈，哪怕是(shi)24小時插(cha)著它也還是(shi)綠燈，因(yin)為(wei)電(dian)池電(dian)壓過(guo)低，與(yu)充(chong)(chong)電(dian)器輸出電(dian)壓相差過(guo)大的(de)話充(chong)(chong)電(dian)器是(shi)無(wu)法將電(dian)沖進電(dian)池的(de)。

這種情況就(jiu)是(shi)(shi)大家平常說的電(dian)池(chi)(chi)被“餓死”了(le)。這種電(dian)池(chi)(chi)塊電(dian)池(chi)(chi)的電(dian)壓一般只有5.6V左右，不(bu)會(hui)超過6V。對(dui)于這樣的電(dian)池(chi)(chi)，大多數是(shi)(shi)換(huan)(huan)電(dian)池(chi)(chi)。但換(huan)(huan)一組電(dian)池(chi)(chi)好幾百(bai)，就(jiu)這樣換(huan)(huan)掉有點(dian)可(ke)惜，尤(you)其是(shi)(shi)剛過保修的電(dian)池(chi)(chi)。

這里介紹五(wu)種比較好的方(fang)法，能將大部分(fen)的這種“餓死”的電瓶(ping)拯(zheng)救過來。注(zhu)意是大部分(fen)不是百分(fen)百。

一、串聯法。在整組電池上另外串聯一個正常電壓的12伏電池。比如說，原車是48V-20AH的電池，那我們再另外串聯一塊12V-20AH的電池。一塊電量充足的12V電池電壓有13V左右，串聯之后能夠提升整組電池的電壓，然后再用他原來的電池充電器進(jin)行(xing)充電(dian)，這樣(yang)的話是可(ke)(ke)以(yi)(yi)將電(dian)充進(jin)去(qu)的，插上充電(dian)器(qi)之后(hou)，充電(dian)器(qi)是紅(hong)燈，此時可(ke)(ke)以(yi)(yi)將電(dian)充進(jin)去(qu)。等充電(dian)器(qi)轉為綠(lv)燈，就把那塊(kuai)另外串聯(lian)上去(qu)的電(dian)池拿(na)掉。然后(hou)再正常充電(dian)就可(ke)(ke)以(yi)(yi)了。

二、并聯法(fa)。這種方法(fa)稍微麻煩一點。比如車輛(liang)原來是48V-20AH的(de)(de)(de)電(dian)(dian)池，我們(men)另外并聯一組，48V-20AH的(de)(de)(de)電(dian)(dian)池。大家知道并聯電(dian)(dian)路各處(chu)的(de)(de)(de)電(dian)(dian)壓是相等的(de)(de)(de)，高(gao)的(de)(de)(de)電(dian)(dian)壓端(duan)會(hui)向低的(de)(de)(de)電(dian)(dian)壓端(duan)流入。這種方法(fa)也是很多(duo)電(dian)(dian)池經銷商在檢測完全(quan)沒有電(dian)(dian)的(de)(de)(de)電(dian)(dian)池所使用的(de)(de)(de)方法(fa)。然(ran)后(hou)進行(xing)充電(dian)(dian)也可以達到充電(dian)(dian)的(de)(de)(de)目的(de)(de)(de)。這個原理(li)跟到，串聯一個電(dian)(dian)池，原理(li)差不多(duo)。也是將整組的(de)(de)(de)電(dian)(dian)壓提(ti)升上去。

三、低壓充(chong)電法。選用小(xiao)一(yi)型號的充(chong)電器(qi)進(jin)行充(chong)電。比如說是一(yi)組60V-20AH的電池，那么我們是用48V-20AH的充(chong)電器(qi)進(jin)行充(chong)電。這樣(yang)大部分的情況下，也(ye)是可以充(chong)進(jin)去(qu)的。原理也(ye)是類似于第一(yi)種，將(jiang)充(chong)電電壓與電池的兩(liang)端電壓更接近(jin)。

四、單(dan)塊電(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)法。將(jiang)單(dan)塊電(dian)(dian)(dian)(dian)池(chi)用12伏的摩托車充(chong)(chong)電(dian)(dian)(dian)(dian)器進行充(chong)(chong)電(dian)(dian)(dian)(dian)，可以(yi)將(jiang)電(dian)(dian)(dian)(dian)池(chi)激活，但這種充(chong)(chong)電(dian)(dian)(dian)(dian)比較慢，一般要充(chong)(chong)7個小時(shi)以(yi)上，電(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)壓(ya)才(cai)會緩(huan)慢回升到12V左右。如果全部單(dan)塊充(chong)(chong)很耗時(shi)間。

五、特殊充電器法。鋰電池充電器它是(shi)自(zi)動識別電(dian)(dian)池電(dian)(dian)壓(ya)(ya)(ya)的，不(bu)管一組電(dian)(dian)池電(dian)(dian)壓(ya)(ya)(ya)有多少伏，都可(ke)以自(zi)動識別電(dian)(dian)壓(ya)(ya)(ya)，他都可(ke)以充電(dian)(dian)進(jin)去。比(bi)如原(yuan)車是(shi)60V-20AH的電(dian)(dian)池，現在只有30V不(bu)到，它照樣可(ke)以往里面充電(dian)(dian)的。隨著電(dian)(dian)壓(ya)(ya)(ya)的升高(gao)，又全適應更(geng)高(gao)一階(jie)的電(dian)(dian)壓(ya)(ya)(ya)，再給電(dian)(dian)池充電(dian)(dian)。臺鈴(ling)、綠佳(jia)電(dian)(dian)動車、金彭(peng)三輪(lun)車配套(tao)過這個品牌的充電(dian)(dian)器。

另外普及下(xia)鋰電池(chi)(chi)“餓死(si)了(le)”怎么激活？筆記本電池(chi)(chi)或者(zhe)手機電池(chi)(chi)

電(dian)(dian)池(chi)(chi)激(ji)活(huo)在聯想(xiang)電(dian)(dian)源(yuan)管理(li)(li)軟件上(shang)面叫做“電(dian)(dian)源(yuan)標尺校(xiao)準”。在PC端用Everest檢測電(dian)(dian)源(yuan)的(de)時(shi)候，有(you)(you)一(yi)個(ge)“設計容量”，底下緊(jin)跟(gen)著(zhu)“完(wan)(wan)(wan)全充(chong)(chong)電(dian)(dian)容量”，如果(guo)兩項的(de)數(shu)值相同(tong)，則會(hui)看(kan)到(dao)再下邊的(de)“電(dian)(dian)池(chi)(chi)損耗"項為0%；一(yi)般來說剛剛出廠的(de)或者長時(shi)間(jian)(jian)放(fang)(fang)置(zhi)未及時(shi)保(bao)養的(de)電(dian)(dian)池(chi)(chi)”完(wan)(wan)(wan)全充(chong)(chong)電(dian)(dian)容量“會(hui)小(xiao)于”設計容量“，此時(shi)就(jiu)會(hui)看(kan)到(dao)電(dian)(dian)池(chi)(chi)損耗是1%。也就(jiu)意味著(zhu)電(dian)(dian)池(chi)(chi)沒有(you)(you)“完(wan)(wan)(wan)全充(chong)(chong)滿”，我(wo)們(men)需要進(jin)行(xing)“完(wan)(wan)(wan)全充(chong)(chong)放(fang)(fang)電(dian)(dian)”（完(wan)(wan)(wan)全放(fang)(fang)電(dian)(dian)之后(hou)不間(jian)(jian)斷充(chong)(chong)12小(xiao)時(shi)至以上(shang)）益(yi)完(wan)(wan)(wan)全“開發”電(dian)(dian)池(chi)(chi)的(de)“潛(qian)能(neng)”。這個(ge)完(wan)(wan)(wan)全充(chong)(chong)放(fang)(fang)電(dian)(dian)的(de)過(guo)程即稱為“激(ji)活(huo)電(dian)(dian)池(chi)(chi)”，聯想(xiang)Thinkpad等的(de)電(dian)(dian)源(yuan)管理(li)(li)軟件有(you)(you)一(yi)個(ge)“電(dian)(dian)源(yuan)標尺校(xiao)準”功能(neng)原理(li)(li)類似。

個(ge)人(ren)覺得(de)一(yi)些(xie)老科(ke)技的(de)電池比如NiMH需要激活。鋰(li)電池理論是需要激化因為需要在(zai)(zai)負極(ji)形(xing)成一(yi)層SEI的(de)保護層。但(dan)是這個(ge)過程實際上已(yi)經(jing)在(zai)(zai)生產測試階段已(yi)經(jing)完成啦。個(ge)人(ren)覺得(de)消費者對電池的(de)誤區造成有(you)這樣的(de)服務。

你的手機(ji)電(dian)(dian)(dian)池(chi)(chi)“餓”死(si)了(le)，開不(bu)了(le)機(ji)充(chong)(chong)不(bu)進電(dian)(dian)(dian)，這時(shi)需要激(ji)(ji)活！首(shou)先所謂(wei)餓死(si)就(jiu)是電(dian)(dian)(dian)池(chi)(chi)一(yi)(yi)直沒電(dian)(dian)(dian)或者(zhe)電(dian)(dian)(dian)量很(hen)低(di)時(shi)導致的電(dian)(dian)(dian)池(chi)(chi)無法再充(chong)(chong)電(dian)(dian)(dian)的現象。然后(hou)所謂(wei)激(ji)(ji)活目前有(you)兩個辦法:一(yi)(yi)是使用(yong)萬能充(chong)(chong)充(chong)(chong)個20分(fen)(fen)鐘左右就(jiu)可(ke)以(yi)激(ji)(ji)活。二是給(gei)手機(ji)維修店有(you)較(jiao)為專業的電(dian)(dian)(dian)壓稍微高(gao)點的比(bi)如12伏的電(dian)(dian)(dian)源(yuan)來激(ji)(ji)活，具體就(jiu)是把(ba)電(dian)(dian)(dian)源(yuan)正(zheng)負極放在電(dian)(dian)(dian)池(chi)(chi)正(zheng)負極幾十(shi)秒甚至幾分(fen)(fen)鐘給(gei)它通通電(dian)(dian)(dian)，打通它！最后(hou)，激(ji)(ji)活后(hou)就(jiu)可(ke)以(yi)和原(yuan)來一(yi)(yi)樣用(yong)直充(chong)(chong)充(chong)(chong)電(dian)(dian)(dian)了(le)，會不(bu)會對壽(shou)命有(you)明顯影響(xiang)還不(bu)知道。

用(yong)儀器充電。（如果上述方式不行，電池也無故障(zhang)，就需要用(yong)‘穩壓電源‘激活，黑色的線連(lian)電池負極，紅色的連(lian)電池正極，充電電壓達到3.8V，即(ji)可）使用(yong)鋰電池的裝置，第(di)一(yi)次使用(yong)不用(yong)充電12小時，這是沒(mei)必要的！
