很(hen)多(duo)人(ren)有不好的(de)(de)習慣，經常(chang)人(ren)不在家將(jiang)電(dian)(dian)(dian)動(dong)車電(dian)(dian)(dian)池放(fang)車上(shang)(shang)，空氣(qi)開關也(ye)不關掉(diao)，放(fang)幾個(ge)月不騎。幾個(ge)月后(hou)再來騎行時就發現車子沒電(dian)(dian)(dian)而且(qie)充(chong)電(dian)(dian)(dian)充(chong)不進去(qu)。充(chong)電(dian)(dian)(dian)器插(cha)上(shang)(shang)去(qu)，但是一(yi)直是綠燈，哪怕(pa)是24小時插(cha)著它(ta)也(ye)還(huan)是綠燈，因為電(dian)(dian)(dian)池電(dian)(dian)(dian)壓過低，與充(chong)電(dian)(dian)(dian)器輸出電(dian)(dian)(dian)壓相差過大的(de)(de)話充(chong)電(dian)(dian)(dian)器是無法將(jiang)電(dian)(dian)(dian)沖進電(dian)(dian)(dian)池的(de)(de)。

這(zhe)種情況(kuang)就是(shi)大家平(ping)常說的(de)電(dian)池(chi)(chi)被“餓死”了。這(zhe)種電(dian)池(chi)(chi)塊電(dian)池(chi)(chi)的(de)電(dian)壓一(yi)般(ban)只(zhi)有(you)5.6V左右，不會超過(guo)6V。對于這(zhe)樣的(de)電(dian)池(chi)(chi)，大多(duo)數(shu)是(shi)換電(dian)池(chi)(chi)。但(dan)換一(yi)組電(dian)池(chi)(chi)好幾百，就這(zhe)樣換掉有(you)點可惜，尤其是(shi)剛過(guo)保修的(de)電(dian)池(chi)(chi)。

這里介(jie)紹五(wu)種比較好的方法，能將大(da)部(bu)分(fen)的這種“餓死(si)”的電瓶拯救過來。注意(yi)是(shi)大(da)部(bu)分(fen)不(bu)是(shi)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行充電(dian)(dian)，這樣的(de)話是(shi)可(ke)(ke)以(yi)將電(dian)(dian)充進去(qu)的(de)，插上充電(dian)(dian)器(qi)之后(hou)，充電(dian)(dian)器(qi)是(shi)紅燈(deng)，此(ci)時可(ke)(ke)以(yi)將電(dian)(dian)充進去(qu)。等充電(dian)(dian)器(qi)轉(zhuan)為綠燈(deng)，就(jiu)把那塊(kuai)另外串(chuan)聯上去(qu)的(de)電(dian)(dian)池拿掉。然(ran)后(hou)再(zai)正常充電(dian)(dian)就(jiu)可(ke)(ke)以(yi)了。

二、并(bing)聯法(fa)。這種方法(fa)稍微麻煩一點。比如車輛原(yuan)(yuan)來是48V-20AH的(de)電(dian)(dian)池(chi)(chi)，我們(men)另外并(bing)聯一組，48V-20AH的(de)電(dian)(dian)池(chi)(chi)。大家知道并(bing)聯電(dian)(dian)路各處(chu)的(de)電(dian)(dian)壓是相等的(de)，高的(de)電(dian)(dian)壓端(duan)會向低的(de)電(dian)(dian)壓端(duan)流入。這種方法(fa)也是很多電(dian)(dian)池(chi)(chi)經銷商在檢測完全(quan)沒有電(dian)(dian)的(de)電(dian)(dian)池(chi)(chi)所使用(yong)的(de)方法(fa)。然后(hou)進(jin)行(xing)充(chong)電(dian)(dian)也可以達到充(chong)電(dian)(dian)的(de)目(mu)的(de)。這個(ge)原(yuan)(yuan)理跟到，串聯一個(ge)電(dian)(dian)池(chi)(chi)，原(yuan)(yuan)理差不多。也是將整組的(de)電(dian)(dian)壓提升上去。

三、低壓(ya)充電(dian)法。選用小(xiao)一型(xing)號的(de)充電(dian)器進(jin)行充電(dian)。比如(ru)說是(shi)一組60V-20AH的(de)電(dian)池，那么(me)我們(men)是(shi)用48V-20AH的(de)充電(dian)器進(jin)行充電(dian)。這樣大部(bu)分的(de)情(qing)況(kuang)下(xia)，也是(shi)可(ke)以充進(jin)去的(de)。原(yuan)理也是(shi)類似于第一種，將充電(dian)電(dian)壓(ya)與電(dian)池的(de)兩(liang)端電(dian)壓(ya)更接近(jin)。

四、單(dan)塊(kuai)電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)法。將單(dan)塊(kuai)電(dian)(dian)(dian)池用12伏(fu)的摩托車充(chong)電(dian)(dian)(dian)器進行充(chong)電(dian)(dian)(dian)，可(ke)以(yi)將電(dian)(dian)(dian)池激活，但這種充(chong)電(dian)(dian)(dian)比較慢，一(yi)般要充(chong)7個小時以(yi)上(shang)，電(dian)(dian)(dian)池電(dian)(dian)(dian)壓才會緩慢回(hui)升到12V左右。如果全部(bu)單(dan)塊(kuai)充(chong)很耗時間。

五、特殊充電器法。鋰電池充電器它(ta)是自動識(shi)別(bie)電(dian)池電(dian)壓(ya)(ya)(ya)的(de)，不(bu)管一組(zu)電(dian)池電(dian)壓(ya)(ya)(ya)有多少伏，都可以(yi)(yi)自動識(shi)別(bie)電(dian)壓(ya)(ya)(ya)，他都可以(yi)(yi)充(chong)電(dian)進去(qu)。比(bi)如原車是60V-20AH的(de)電(dian)池，現在只有30V不(bu)到，它(ta)照樣可以(yi)(yi)往里面充(chong)電(dian)的(de)。隨著電(dian)壓(ya)(ya)(ya)的(de)升高，又全(quan)適應更(geng)高一階的(de)電(dian)壓(ya)(ya)(ya)，再給電(dian)池充(chong)電(dian)。臺鈴、綠佳(jia)電(dian)動車、金彭三輪車配套(tao)過這個品牌(pai)的(de)充(chong)電(dian)器。

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

電(dian)(dian)(dian)(dian)池(chi)(chi)激活在(zai)聯(lian)想(xiang)電(dian)(dian)(dian)(dian)源(yuan)(yuan)管(guan)理(li)軟(ruan)件上面叫做“電(dian)(dian)(dian)(dian)源(yuan)(yuan)標(biao)尺校準(zhun)”。在(zai)PC端用Everest檢測(ce)電(dian)(dian)(dian)(dian)源(yuan)(yuan)的(de)(de)時(shi)候，有(you)一個(ge)“設計(ji)容量(liang)”，底下緊跟(gen)著(zhu)“完(wan)(wan)(wan)全(quan)充(chong)(chong)電(dian)(dian)(dian)(dian)容量(liang)”，如果兩項的(de)(de)數(shu)值相(xiang)同，則會(hui)(hui)看到再下邊的(de)(de)“電(dian)(dian)(dian)(dian)池(chi)(chi)損(sun)耗"項為0%；一般(ban)來(lai)說剛剛出廠(chang)的(de)(de)或(huo)者(zhe)長時(shi)間放置未(wei)及時(shi)保養(yang)的(de)(de)電(dian)(dian)(dian)(dian)池(chi)(chi)”完(wan)(wan)(wan)全(quan)充(chong)(chong)電(dian)(dian)(dian)(dian)容量(liang)“會(hui)(hui)小(xiao)(xiao)于(yu)”設計(ji)容量(liang)“，此(ci)時(shi)就會(hui)(hui)看到電(dian)(dian)(dian)(dian)池(chi)(chi)損(sun)耗是(shi)1%。也(ye)就意味著(zhu)電(dian)(dian)(dian)(dian)池(chi)(chi)沒有(you)“完(wan)(wan)(wan)全(quan)充(chong)(chong)滿”，我們需要進(jin)行“完(wan)(wan)(wan)全(quan)充(chong)(chong)放電(dian)(dian)(dian)(dian)”（完(wan)(wan)(wan)全(quan)放電(dian)(dian)(dian)(dian)之后(hou)不間斷充(chong)(chong)12小(xiao)(xiao)時(shi)至以(yi)上）益完(wan)(wan)(wan)全(quan)“開發”電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)“潛能”。這個(ge)完(wan)(wan)(wan)全(quan)充(chong)(chong)放電(dian)(dian)(dian)(dian)的(de)(de)過程即稱為“激活電(dian)(dian)(dian)(dian)池(chi)(chi)”，聯(lian)想(xiang)Thinkpad等的(de)(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)管(guan)理(li)軟(ruan)件有(you)一個(ge)“電(dian)(dian)(dian)(dian)源(yuan)(yuan)標(biao)尺校準(zhun)”功能原理(li)類似(si)。

個人覺得一(yi)些老科技的電池比如(ru)NiMH需要激活。鋰(li)電池理(li)論(lun)是需要激化因為需要在(zai)負(fu)極形成(cheng)(cheng)一(yi)層SEI的保(bao)護層。但是這個過程實際(ji)上已經(jing)在(zai)生產測試(shi)階段已經(jing)完成(cheng)(cheng)啦(la)。個人覺得消費者對(dui)電池的誤區造成(cheng)(cheng)有(you)這樣的服務。

你的(de)手機電(dian)(dian)池“餓”死了(le)，開(kai)不(bu)(bu)了(le)機充(chong)不(bu)(bu)進(jin)電(dian)(dian)，這時需要激活(huo)！首先(xian)所謂餓死就(jiu)(jiu)是電(dian)(dian)池一直沒電(dian)(dian)或者電(dian)(dian)量很低時導致的(de)電(dian)(dian)池無法再(zai)充(chong)電(dian)(dian)的(de)現象。然后所謂激活(huo)目前有(you)兩個(ge)辦法:一是使用萬能充(chong)充(chong)個(ge)20分鐘(zhong)左右就(jiu)(jiu)可以(yi)激活(huo)。二(er)是給(gei)手機維(wei)修店有(you)較為專(zhuan)業的(de)電(dian)(dian)壓稍(shao)微高點的(de)比如12伏的(de)電(dian)(dian)源(yuan)來激活(huo)，具體就(jiu)(jiu)是把(ba)電(dian)(dian)源(yuan)正(zheng)負(fu)極(ji)放在電(dian)(dian)池正(zheng)負(fu)極(ji)幾十秒甚至幾分鐘(zhong)給(gei)它通(tong)通(tong)電(dian)(dian)，打通(tong)它！最后，激活(huo)后就(jiu)(jiu)可以(yi)和原來一樣用直充(chong)充(chong)電(dian)(dian)了(le)，會(hui)不(bu)(bu)會(hui)對壽命有(you)明顯(xian)影響還不(bu)(bu)知道。

用儀器(qi)充電(dian)。（如(ru)果上述(shu)方式不行，電(dian)池(chi)(chi)也無(wu)故障，就(jiu)需要用‘穩壓電(dian)源(yuan)‘激活，黑色的線(xian)連電(dian)池(chi)(chi)負極，紅色的連電(dian)池(chi)(chi)正極，充電(dian)電(dian)壓達到3.8V，即可）使(shi)(shi)用鋰電(dian)池(chi)(chi)的裝(zhuang)置，第(di)一次使(shi)(shi)用不用充電(dian)12小時，這(zhe)是沒必要的！
