很多(duo)人(ren)有不好(hao)的習慣，經常(chang)人(ren)不在(zai)家將電(dian)(dian)(dian)動車(che)(che)電(dian)(dian)(dian)池放(fang)車(che)(che)上，空氣開關也不關掉，放(fang)幾(ji)個(ge)月不騎(qi)。幾(ji)個(ge)月后再來騎(qi)行時就發現車(che)(che)子沒(mei)電(dian)(dian)(dian)而且充電(dian)(dian)(dian)充不進去。充電(dian)(dian)(dian)器(qi)插上去，但是(shi)一直是(shi)綠燈，哪怕(pa)是(shi)24小時插著(zhu)它也還是(shi)綠燈，因為電(dian)(dian)(dian)池電(dian)(dian)(dian)壓(ya)過(guo)低，與充電(dian)(dian)(dian)器(qi)輸出電(dian)(dian)(dian)壓(ya)相差過(guo)大(da)的話(hua)充電(dian)(dian)(dian)器(qi)是(shi)無(wu)法將電(dian)(dian)(dian)沖進電(dian)(dian)(dian)池的。

這種情況就是大家(jia)平常說的電(dian)池(chi)被“餓死”了。這種電(dian)池(chi)塊電(dian)池(chi)的電(dian)壓一(yi)般只有(you)5.6V左(zuo)右，不會超(chao)過(guo)6V。對于這樣(yang)的電(dian)池(chi)，大多數是換電(dian)池(chi)。但(dan)換一(yi)組電(dian)池(chi)好幾百，就這樣(yang)換掉有(you)點可惜(xi)，尤其是剛過(guo)保修的電(dian)池(chi)。

這里介紹五種(zhong)比(bi)較好的方(fang)法，能將大部(bu)分(fen)(fen)的這種(zhong)“餓死”的電瓶拯救過來。注意是大部(bu)分(fen)(fen)不是百(bai)分(fen)(fen)百(bai)。

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行(xing)充(chong)電(dian)，這(zhe)樣的話是可以(yi)(yi)將電(dian)充(chong)進去的，插(cha)上(shang)(shang)充(chong)電(dian)器(qi)之后，充(chong)電(dian)器(qi)是紅燈，此時可以(yi)(yi)將電(dian)充(chong)進去。等充(chong)電(dian)器(qi)轉為綠燈，就把那(nei)塊另外串聯上(shang)(shang)去的電(dian)池(chi)拿掉。然后再正常(chang)充(chong)電(dian)就可以(yi)(yi)了。

二、并(bing)聯法(fa)。這種方法(fa)稍微(wei)麻煩一點(dian)。比如車輛原來是48V-20AH的電(dian)(dian)(dian)池(chi)，我(wo)們另外并(bing)聯一組，48V-20AH的電(dian)(dian)(dian)池(chi)。大家(jia)知道并(bing)聯電(dian)(dian)(dian)路各處的電(dian)(dian)(dian)壓是相等的，高的電(dian)(dian)(dian)壓端會向低的電(dian)(dian)(dian)壓端流入。這種方法(fa)也(ye)(ye)是很多(duo)電(dian)(dian)(dian)池(chi)經銷商在檢測完(wan)全沒(mei)有電(dian)(dian)(dian)的電(dian)(dian)(dian)池(chi)所使用的方法(fa)。然后進行(xing)充(chong)電(dian)(dian)(dian)也(ye)(ye)可(ke)以(yi)達到充(chong)電(dian)(dian)(dian)的目的。這個原理跟到，串聯一個電(dian)(dian)(dian)池(chi)，原理差不多(duo)。也(ye)(ye)是將整組的電(dian)(dian)(dian)壓提升上去(qu)。

三、低壓充(chong)(chong)電(dian)(dian)法。選用(yong)小一(yi)型號的(de)充(chong)(chong)電(dian)(dian)器進(jin)行充(chong)(chong)電(dian)(dian)。比如說是一(yi)組(zu)60V-20AH的(de)電(dian)(dian)池，那么我們是用(yong)48V-20AH的(de)充(chong)(chong)電(dian)(dian)器進(jin)行充(chong)(chong)電(dian)(dian)。這(zhe)樣大部分(fen)的(de)情況(kuang)下，也是可以充(chong)(chong)進(jin)去(qu)的(de)。原理(li)也是類似(si)于第一(yi)種，將充(chong)(chong)電(dian)(dian)電(dian)(dian)壓與(yu)電(dian)(dian)池的(de)兩端電(dian)(dian)壓更接近。

四、單(dan)(dan)塊電(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)法。將單(dan)(dan)塊電(dian)(dian)(dian)(dian)池(chi)用12伏的摩托車充(chong)電(dian)(dian)(dian)(dian)器進行充(chong)電(dian)(dian)(dian)(dian)，可以將電(dian)(dian)(dian)(dian)池(chi)激活，但(dan)這種充(chong)電(dian)(dian)(dian)(dian)比較(jiao)慢(man)，一(yi)般要充(chong)7個小時以上，電(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)壓才會緩慢(man)回(hui)升到(dao)12V左右。如果全部單(dan)(dan)塊充(chong)很耗(hao)時間(jian)。

五、特殊充電器法。鋰電池充電器它是(shi)自動識別(bie)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)的，不管(guan)一組電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)有(you)多(duo)少伏，都(dou)可(ke)以(yi)自動識別(bie)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，他都(dou)可(ke)以(yi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)進(jin)去。比如原車是(shi)60V-20AH的電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)，現在(zai)只有(you)30V不到，它照樣可(ke)以(yi)往里(li)面充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)的。隨著電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)的升高，又全適應(ying)更高一階的電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，再給電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。臺(tai)鈴、綠佳電(dian)(dian)(dian)(dian)(dian)(dian)動車、金彭三輪(lun)車配套過這個品(pin)牌的充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器。

另外普及下(xia)鋰電(dian)池“餓死了”怎么激活？筆記本電(dian)池或者手(shou)機電(dian)池

電(dian)(dian)(dian)池(chi)激活在(zai)聯(lian)想電(dian)(dian)(dian)源(yuan)(yuan)(yuan)管理軟件上面(mian)叫做“電(dian)(dian)(dian)源(yuan)(yuan)(yuan)標尺(chi)校準(zhun)”。在(zai)PC端用Everest檢測電(dian)(dian)(dian)源(yuan)(yuan)(yuan)的(de)時(shi)(shi)(shi)候，有(you)一(yi)(yi)個“設計容量”，底下緊跟(gen)著(zhu)“完(wan)(wan)(wan)全(quan)(quan)(quan)充(chong)(chong)電(dian)(dian)(dian)容量”，如(ru)果兩項的(de)數值(zhi)相(xiang)同，則會看到(dao)再下邊(bian)的(de)“電(dian)(dian)(dian)池(chi)損耗(hao)"項為(wei)0%；一(yi)(yi)般來說(shuo)剛剛出廠的(de)或者(zhe)長(chang)時(shi)(shi)(shi)間放(fang)置未及時(shi)(shi)(shi)保養的(de)電(dian)(dian)(dian)池(chi)”完(wan)(wan)(wan)全(quan)(quan)(quan)充(chong)(chong)電(dian)(dian)(dian)容量“會小(xiao)于”設計容量“，此時(shi)(shi)(shi)就會看到(dao)電(dian)(dian)(dian)池(chi)損耗(hao)是1%。也就意(yi)味著(zhu)電(dian)(dian)(dian)池(chi)沒有(you)“完(wan)(wan)(wan)全(quan)(quan)(quan)充(chong)(chong)滿”，我們(men)需(xu)要進行“完(wan)(wan)(wan)全(quan)(quan)(quan)充(chong)(chong)放(fang)電(dian)(dian)(dian)”（完(wan)(wan)(wan)全(quan)(quan)(quan)放(fang)電(dian)(dian)(dian)之后(hou)不間斷(duan)充(chong)(chong)12小(xiao)時(shi)(shi)(shi)至以上）益完(wan)(wan)(wan)全(quan)(quan)(quan)“開(kai)發”電(dian)(dian)(dian)池(chi)的(de)“潛能”。這個完(wan)(wan)(wan)全(quan)(quan)(quan)充(chong)(chong)放(fang)電(dian)(dian)(dian)的(de)過程(cheng)即稱為(wei)“激活電(dian)(dian)(dian)池(chi)”，聯(lian)想Thinkpad等的(de)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)管理軟件有(you)一(yi)(yi)個“電(dian)(dian)(dian)源(yuan)(yuan)(yuan)標尺(chi)校準(zhun)”功能原(yuan)理類似。

個人覺(jue)得(de)一些老科技的(de)(de)電(dian)池比如NiMH需(xu)(xu)要激(ji)活(huo)。鋰電(dian)池理論(lun)是(shi)需(xu)(xu)要激(ji)化因為需(xu)(xu)要在負極形成(cheng)一層SEI的(de)(de)保護層。但是(shi)這個過(guo)程實際上已經在生(sheng)產測試階段已經完成(cheng)啦。個人覺(jue)得(de)消費者對(dui)電(dian)池的(de)(de)誤(wu)區(qu)造(zao)成(cheng)有這樣的(de)(de)服(fu)務。

你的(de)(de)手機(ji)電(dian)(dian)(dian)池“餓(e)”死了(le)，開不(bu)(bu)了(le)機(ji)充(chong)(chong)(chong)不(bu)(bu)進電(dian)(dian)(dian)，這時(shi)需要(yao)激(ji)(ji)(ji)活(huo)！首先所(suo)謂(wei)餓(e)死就是(shi)電(dian)(dian)(dian)池一(yi)直沒電(dian)(dian)(dian)或(huo)者電(dian)(dian)(dian)量很低時(shi)導致(zhi)的(de)(de)電(dian)(dian)(dian)池無法再充(chong)(chong)(chong)電(dian)(dian)(dian)的(de)(de)現象(xiang)。然后所(suo)謂(wei)激(ji)(ji)(ji)活(huo)目前有兩(liang)個辦法:一(yi)是(shi)使用萬能充(chong)(chong)(chong)充(chong)(chong)(chong)個20分鐘(zhong)左右(you)就可以(yi)(yi)激(ji)(ji)(ji)活(huo)。二是(shi)給手機(ji)維修(xiu)店有較(jiao)為專業(ye)的(de)(de)電(dian)(dian)(dian)壓(ya)稍微高點的(de)(de)比(bi)如(ru)12伏(fu)的(de)(de)電(dian)(dian)(dian)源(yuan)來激(ji)(ji)(ji)活(huo)，具體(ti)就是(shi)把(ba)電(dian)(dian)(dian)源(yuan)正負極放在電(dian)(dian)(dian)池正負極幾十秒(miao)甚(shen)至幾分鐘(zhong)給它(ta)通通電(dian)(dian)(dian)，打通它(ta)！最后，激(ji)(ji)(ji)活(huo)后就可以(yi)(yi)和原來一(yi)樣用直充(chong)(chong)(chong)充(chong)(chong)(chong)電(dian)(dian)(dian)了(le)，會不(bu)(bu)會對壽命有明顯影響還不(bu)(bu)知(zhi)道。

用儀器充(chong)電(dian)。（如(ru)果(guo)上(shang)述方(fang)式不行，電(dian)池(chi)也無(wu)故障(zhang)，就需要用‘穩壓電(dian)源‘激活，黑色的線連(lian)(lian)電(dian)池(chi)負極，紅(hong)色的連(lian)(lian)電(dian)池(chi)正(zheng)極，充(chong)電(dian)電(dian)壓達到(dao)3.8V，即可(ke)）使用鋰電(dian)池(chi)的裝置，第一次使用不用充(chong)電(dian)12小時，這是(shi)沒必要的！
