很多人(ren)有不(bu)好的(de)習慣，經常人(ren)不(bu)在家將電(dian)(dian)動(dong)車電(dian)(dian)池(chi)放(fang)(fang)車上，空氣開關(guan)也(ye)不(bu)關(guan)掉，放(fang)(fang)幾個月不(bu)騎。幾個月后(hou)再來騎行時(shi)(shi)就發現車子沒電(dian)(dian)而且充(chong)電(dian)(dian)充(chong)不(bu)進(jin)去(qu)。充(chong)電(dian)(dian)器插(cha)上去(qu)，但是(shi)一直是(shi)綠燈，哪怕是(shi)24小時(shi)(shi)插(cha)著它也(ye)還是(shi)綠燈，因(yin)為電(dian)(dian)池(chi)電(dian)(dian)壓過低，與充(chong)電(dian)(dian)器輸出電(dian)(dian)壓相差過大的(de)話充(chong)電(dian)(dian)器是(shi)無法將電(dian)(dian)沖(chong)進(jin)電(dian)(dian)池(chi)的(de)。

這種情況就(jiu)是大家(jia)平(ping)常(chang)說的電(dian)(dian)(dian)池(chi)被“餓死”了。這種電(dian)(dian)(dian)池(chi)塊電(dian)(dian)(dian)池(chi)的電(dian)(dian)(dian)壓一(yi)般(ban)只(zhi)有5.6V左右，不會超過6V。對(dui)于這樣(yang)的電(dian)(dian)(dian)池(chi)，大多數是換(huan)電(dian)(dian)(dian)池(chi)。但換(huan)一(yi)組電(dian)(dian)(dian)池(chi)好幾百，就(jiu)這樣(yang)換(huan)掉有點(dian)可惜，尤其(qi)是剛過保修的電(dian)(dian)(dian)池(chi)。

這(zhe)(zhe)里介紹(shao)五種比較好的(de)方法(fa)，能將大部(bu)分的(de)這(zhe)(zhe)種“餓死”的(de)電(dian)瓶拯救過來(lai)。注意是大部(bu)分不是百(bai)分百(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(jin)行充(chong)(chong)電(dian)(dian)，這(zhe)樣的(de)話(hua)是可以將電(dian)(dian)充(chong)(chong)進(jin)去(qu)的(de)，插上(shang)充(chong)(chong)電(dian)(dian)器(qi)之后(hou)，充(chong)(chong)電(dian)(dian)器(qi)是紅燈，此時可以將電(dian)(dian)充(chong)(chong)進(jin)去(qu)。等充(chong)(chong)電(dian)(dian)器(qi)轉為(wei)綠燈，就把那塊另外(wai)串聯上(shang)去(qu)的(de)電(dian)(dian)池拿掉。然后(hou)再正(zheng)常充(chong)(chong)電(dian)(dian)就可以了。

二(er)、并(bing)聯法(fa)(fa)。這種方法(fa)(fa)稍微麻煩一點(dian)。比如車(che)輛原來是48V-20AH的(de)電(dian)(dian)(dian)池(chi)(chi)，我們另外并(bing)聯一組，48V-20AH的(de)電(dian)(dian)(dian)池(chi)(chi)。大家(jia)知道并(bing)聯電(dian)(dian)(dian)路各處的(de)電(dian)(dian)(dian)壓(ya)是相等的(de)，高的(de)電(dian)(dian)(dian)壓(ya)端會向低的(de)電(dian)(dian)(dian)壓(ya)端流(liu)入。這種方法(fa)(fa)也是很多(duo)電(dian)(dian)(dian)池(chi)(chi)經銷商在(zai)檢測完全(quan)沒(mei)有電(dian)(dian)(dian)的(de)電(dian)(dian)(dian)池(chi)(chi)所使用(yong)的(de)方法(fa)(fa)。然后進行充(chong)電(dian)(dian)(dian)也可以達到(dao)充(chong)電(dian)(dian)(dian)的(de)目的(de)。這個(ge)原理(li)跟到(dao)，串聯一個(ge)電(dian)(dian)(dian)池(chi)(chi)，原理(li)差不(bu)多(duo)。也是將整組的(de)電(dian)(dian)(dian)壓(ya)提升上(shang)去。

三(san)、低壓(ya)充(chong)電(dian)(dian)(dian)法。選用小一型號(hao)的(de)(de)充(chong)電(dian)(dian)(dian)器(qi)(qi)進行充(chong)電(dian)(dian)(dian)。比如說是(shi)一組60V-20AH的(de)(de)電(dian)(dian)(dian)池，那么(me)我們是(shi)用48V-20AH的(de)(de)充(chong)電(dian)(dian)(dian)器(qi)(qi)進行充(chong)電(dian)(dian)(dian)。這樣大部分(fen)的(de)(de)情況下，也是(shi)可以充(chong)進去(qu)的(de)(de)。原(yuan)理也是(shi)類似于第一種，將充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)與電(dian)(dian)(dian)池的(de)(de)兩端(duan)電(dian)(dian)(dian)壓(ya)更接近。

四(si)、單(dan)塊(kuai)(kuai)電(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)法。將(jiang)單(dan)塊(kuai)(kuai)電(dian)(dian)(dian)池(chi)(chi)(chi)用12伏的摩托車充(chong)(chong)電(dian)(dian)(dian)器進行充(chong)(chong)電(dian)(dian)(dian)，可以將(jiang)電(dian)(dian)(dian)池(chi)(chi)(chi)激活(huo)，但這種(zhong)充(chong)(chong)電(dian)(dian)(dian)比較(jiao)慢(man)，一般(ban)要充(chong)(chong)7個(ge)小(xiao)時(shi)以上，電(dian)(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)(dian)壓才會(hui)緩(huan)慢(man)回(hui)升到12V左右。如果全部單(dan)塊(kuai)(kuai)充(chong)(chong)很(hen)耗時(shi)間。

五、特殊充電器法。鋰電池充電器它(ta)是(shi)自動(dong)識(shi)別電(dian)(dian)池(chi)電(dian)(dian)壓的(de)(de)，不(bu)管一(yi)組電(dian)(dian)池(chi)電(dian)(dian)壓有多少伏，都(dou)可以(yi)自動(dong)識(shi)別電(dian)(dian)壓，他都(dou)可以(yi)充(chong)(chong)電(dian)(dian)進去(qu)。比如原車(che)是(shi)60V-20AH的(de)(de)電(dian)(dian)池(chi)，現在只有30V不(bu)到，它(ta)照樣可以(yi)往里面(mian)充(chong)(chong)電(dian)(dian)的(de)(de)。隨(sui)著電(dian)(dian)壓的(de)(de)升高，又全適應更高一(yi)階的(de)(de)電(dian)(dian)壓，再給電(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)。臺鈴、綠佳電(dian)(dian)動(dong)車(che)、金彭三(san)輪車(che)配套過這(zhe)個品牌(pai)的(de)(de)充(chong)(chong)電(dian)(dian)器(qi)。

另外普及下鋰電(dian)池(chi)“餓死了”怎么激活？筆(bi)記本電(dian)池(chi)或者(zhe)手機(ji)電(dian)池(chi)

電(dian)(dian)(dian)池(chi)激活(huo)在聯想電(dian)(dian)(dian)源(yuan)管理軟件上(shang)面叫做(zuo)“電(dian)(dian)(dian)源(yuan)標尺校(xiao)準”。在PC端用(yong)Everest檢測電(dian)(dian)(dian)源(yuan)的(de)(de)(de)(de)(de)時(shi)候，有一個(ge)“設計容(rong)量(liang)(liang)”，底下(xia)緊(jin)跟(gen)著“完(wan)(wan)全(quan)(quan)(quan)充(chong)電(dian)(dian)(dian)容(rong)量(liang)(liang)”，如(ru)果兩項的(de)(de)(de)(de)(de)數(shu)值相同(tong)，則會看到再下(xia)邊的(de)(de)(de)(de)(de)“電(dian)(dian)(dian)池(chi)損(sun)耗(hao)"項為0%；一般來(lai)說剛剛出廠(chang)的(de)(de)(de)(de)(de)或者長(chang)時(shi)間放(fang)置未及(ji)時(shi)保(bao)養的(de)(de)(de)(de)(de)電(dian)(dian)(dian)池(chi)”完(wan)(wan)全(quan)(quan)(quan)充(chong)電(dian)(dian)(dian)容(rong)量(liang)(liang)“會小于”設計容(rong)量(liang)(liang)“，此時(shi)就會看到電(dian)(dian)(dian)池(chi)損(sun)耗(hao)是1%。也(ye)就意味(wei)著電(dian)(dian)(dian)池(chi)沒有“完(wan)(wan)全(quan)(quan)(quan)充(chong)滿(man)”，我們需要(yao)進行“完(wan)(wan)全(quan)(quan)(quan)充(chong)放(fang)電(dian)(dian)(dian)”（完(wan)(wan)全(quan)(quan)(quan)放(fang)電(dian)(dian)(dian)之(zhi)后不間斷充(chong)12小時(shi)至(zhi)以上(shang)）益完(wan)(wan)全(quan)(quan)(quan)“開發”電(dian)(dian)(dian)池(chi)的(de)(de)(de)(de)(de)“潛(qian)能(neng)”。這個(ge)完(wan)(wan)全(quan)(quan)(quan)充(chong)放(fang)電(dian)(dian)(dian)的(de)(de)(de)(de)(de)過程即稱為“激活(huo)電(dian)(dian)(dian)池(chi)”，聯想Thinkpad等的(de)(de)(de)(de)(de)電(dian)(dian)(dian)源(yuan)管理軟件有一個(ge)“電(dian)(dian)(dian)源(yuan)標尺校(xiao)準”功能(neng)原理類(lei)似。

個人覺得一(yi)些老(lao)科技的電(dian)池比(bi)如(ru)NiMH需要(yao)激活。鋰電(dian)池理論是需要(yao)激化因為需要(yao)在負極形成(cheng)(cheng)一(yi)層(ceng)SEI的保護(hu)層(ceng)。但是這(zhe)個過程實際上已經在生產測試階(jie)段已經完成(cheng)(cheng)啦。個人覺得消費者對電(dian)池的誤區造成(cheng)(cheng)有這(zhe)樣(yang)的服務。

你的(de)手機(ji)(ji)電(dian)(dian)池“餓”死了(le)，開(kai)不(bu)了(le)機(ji)(ji)充(chong)不(bu)進(jin)電(dian)(dian)，這時需要激(ji)(ji)活(huo)！首(shou)先所(suo)謂餓死就(jiu)是電(dian)(dian)池一直(zhi)沒(mei)電(dian)(dian)或者電(dian)(dian)量(liang)很低(di)時導致的(de)電(dian)(dian)池無法(fa)再充(chong)電(dian)(dian)的(de)現象。然后所(suo)謂激(ji)(ji)活(huo)目前有(you)(you)兩個辦法(fa):一是使用萬能充(chong)充(chong)個20分(fen)鐘(zhong)左右(you)就(jiu)可以激(ji)(ji)活(huo)。二是給(gei)手機(ji)(ji)維修店有(you)(you)較為專(zhuan)業的(de)電(dian)(dian)壓(ya)稍微高點的(de)比如12伏的(de)電(dian)(dian)源來激(ji)(ji)活(huo)，具體就(jiu)是把(ba)電(dian)(dian)源正(zheng)(zheng)負極放(fang)在電(dian)(dian)池正(zheng)(zheng)負極幾十秒(miao)甚至幾分(fen)鐘(zhong)給(gei)它通通電(dian)(dian)，打通它！最(zui)后，激(ji)(ji)活(huo)后就(jiu)可以和(he)原來一樣用直(zhi)充(chong)充(chong)電(dian)(dian)了(le)，會不(bu)會對壽命有(you)(you)明顯影(ying)響還不(bu)知道(dao)。

用(yong)儀器充電(dian)。（如(ru)果(guo)上述方式不行，電(dian)池(chi)也無故障，就需要用(yong)‘穩壓(ya)電(dian)源‘激活，黑色(se)的(de)線連電(dian)池(chi)負極，紅色(se)的(de)連電(dian)池(chi)正極，充電(dian)電(dian)壓(ya)達到3.8V，即可）使用(yong)鋰電(dian)池(chi)的(de)裝置，第一次使用(yong)不用(yong)充電(dian)12小(xiao)時，這(zhe)是沒(mei)必要的(de)！
