很多人有不(bu)好的(de)習慣，經常人不(bu)在家(jia)將(jiang)電(dian)動車電(dian)池放(fang)車上，空氣開關也不(bu)關掉，放(fang)幾個月不(bu)騎。幾個月后再來騎行時(shi)就發現車子沒電(dian)而且充(chong)(chong)電(dian)充(chong)(chong)不(bu)進去(qu)。充(chong)(chong)電(dian)器插上去(qu)，但是(shi)(shi)一直是(shi)(shi)綠燈(deng)(deng)，哪怕(pa)是(shi)(shi)24小時(shi)插著(zhu)它也還(huan)是(shi)(shi)綠燈(deng)(deng)，因(yin)為電(dian)池電(dian)壓過低，與充(chong)(chong)電(dian)器輸出電(dian)壓相差過大的(de)話(hua)充(chong)(chong)電(dian)器是(shi)(shi)無法(fa)將(jiang)電(dian)沖進電(dian)池的(de)。

這(zhe)種情況就是大家平常說的電池(chi)被(bei)“餓死(si)”了。這(zhe)種電池(chi)塊(kuai)電池(chi)的電壓一(yi)般(ban)只有5.6V左右，不(bu)會(hui)超過(guo)6V。對于這(zhe)樣(yang)的電池(chi)，大多(duo)數是換電池(chi)。但換一(yi)組電池(chi)好幾百，就這(zhe)樣(yang)換掉有點(dian)可惜，尤其是剛(gang)過(guo)保修的電池(chi)。

這里介紹五種(zhong)比較好的方法(fa)，能將(jiang)大部分(fen)的這種(zhong)“餓(e)死”的電瓶拯救過來。注(zhu)意是大部分(fen)不(bu)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行(xing)充(chong)(chong)電(dian)(dian)(dian)，這樣(yang)的話是(shi)可(ke)以將(jiang)電(dian)(dian)(dian)充(chong)(chong)進去的，插上(shang)充(chong)(chong)電(dian)(dian)(dian)器(qi)之后(hou)，充(chong)(chong)電(dian)(dian)(dian)器(qi)是(shi)紅燈(deng)，此時可(ke)以將(jiang)電(dian)(dian)(dian)充(chong)(chong)進去。等充(chong)(chong)電(dian)(dian)(dian)器(qi)轉為綠燈(deng)，就把那塊另外串聯上(shang)去的電(dian)(dian)(dian)池拿掉(diao)。然(ran)后(hou)再正常充(chong)(chong)電(dian)(dian)(dian)就可(ke)以了。

二、并(bing)聯(lian)法(fa)。這種(zhong)方(fang)法(fa)稍微麻煩(fan)一點。比(bi)如(ru)車輛原來是48V-20AH的(de)(de)(de)電(dian)(dian)(dian)池(chi)，我們另外并(bing)聯(lian)一組，48V-20AH的(de)(de)(de)電(dian)(dian)(dian)池(chi)。大家知道(dao)并(bing)聯(lian)電(dian)(dian)(dian)路各處(chu)的(de)(de)(de)電(dian)(dian)(dian)壓(ya)是相等的(de)(de)(de)，高的(de)(de)(de)電(dian)(dian)(dian)壓(ya)端(duan)會向低的(de)(de)(de)電(dian)(dian)(dian)壓(ya)端(duan)流入。這種(zhong)方(fang)法(fa)也(ye)是很多電(dian)(dian)(dian)池(chi)經銷商在檢測完全沒有(you)電(dian)(dian)(dian)的(de)(de)(de)電(dian)(dian)(dian)池(chi)所使用的(de)(de)(de)方(fang)法(fa)。然(ran)后(hou)進(jin)行充電(dian)(dian)(dian)也(ye)可以達到(dao)充電(dian)(dian)(dian)的(de)(de)(de)目的(de)(de)(de)。這個原理跟到(dao)，串聯(lian)一個電(dian)(dian)(dian)池(chi)，原理差不多。也(ye)是將整組的(de)(de)(de)電(dian)(dian)(dian)壓(ya)提(ti)升(sheng)上去。

三(san)、低壓充(chong)(chong)(chong)電(dian)(dian)法。選(xuan)用小一(yi)型號的充(chong)(chong)(chong)電(dian)(dian)器進(jin)行充(chong)(chong)(chong)電(dian)(dian)。比如說是(shi)一(yi)組60V-20AH的電(dian)(dian)池，那(nei)么(me)我們(men)是(shi)用48V-20AH的充(chong)(chong)(chong)電(dian)(dian)器進(jin)行充(chong)(chong)(chong)電(dian)(dian)。這樣大(da)部分的情(qing)況下(xia)，也是(shi)可以充(chong)(chong)(chong)進(jin)去的。原理(li)也是(shi)類(lei)似于第一(yi)種，將充(chong)(chong)(chong)電(dian)(dian)電(dian)(dian)壓與電(dian)(dian)池的兩端電(dian)(dian)壓更接近(jin)。

四、單塊電(dian)(dian)池充(chong)(chong)電(dian)(dian)法。將(jiang)單塊電(dian)(dian)池用12伏的摩托車充(chong)(chong)電(dian)(dian)器進行充(chong)(chong)電(dian)(dian)，可以(yi)將(jiang)電(dian)(dian)池激(ji)活，但這種(zhong)充(chong)(chong)電(dian)(dian)比較慢，一般要充(chong)(chong)7個(ge)小時以(yi)上，電(dian)(dian)池電(dian)(dian)壓才(cai)會緩(huan)慢回升到12V左右。如果全部單塊充(chong)(chong)很耗(hao)時間。

五、特殊充電器法。鋰電池充電器它是自動(dong)識(shi)別電(dian)(dian)池電(dian)(dian)壓的，不管一(yi)組電(dian)(dian)池電(dian)(dian)壓有(you)多少伏，都可以(yi)自動(dong)識(shi)別電(dian)(dian)壓，他都可以(yi)充(chong)電(dian)(dian)進去。比如原車(che)是60V-20AH的電(dian)(dian)池，現(xian)在只(zhi)有(you)30V不到(dao)，它照(zhao)樣可以(yi)往里面充(chong)電(dian)(dian)的。隨著電(dian)(dian)壓的升高，又(you)全適應更高一(yi)階(jie)的電(dian)(dian)壓，再給電(dian)(dian)池充(chong)電(dian)(dian)。臺(tai)鈴、綠(lv)佳電(dian)(dian)動(dong)車(che)、金彭三輪車(che)配(pei)套(tao)過這個品(pin)牌的充(chong)電(dian)(dian)器。

另外普及下鋰電(dian)池(chi)“餓死了”怎么激活(huo)？筆記本電(dian)池(chi)或者手機電(dian)池(chi)

電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)激活在(zai)聯(lian)想電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)管(guan)(guan)理軟(ruan)件上(shang)面(mian)叫做“電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)標尺校準”。在(zai)PC端用Everest檢測(ce)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)的(de)(de)(de)時(shi)(shi)候，有(you)一個(ge)“設計(ji)容(rong)量(liang)”，底(di)下(xia)(xia)緊跟著“完(wan)全(quan)(quan)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)量(liang)”，如果(guo)兩(liang)項的(de)(de)(de)數值相同，則會看到(dao)再下(xia)(xia)邊(bian)的(de)(de)(de)“電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)損耗"項為(wei)0%；一般來說(shuo)剛剛出(chu)廠的(de)(de)(de)或者(zhe)長(chang)時(shi)(shi)間放置未及時(shi)(shi)保養(yang)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)”完(wan)全(quan)(quan)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)量(liang)“會小(xiao)于”設計(ji)容(rong)量(liang)“，此時(shi)(shi)就(jiu)會看到(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)損耗是1%。也就(jiu)意味(wei)著電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)沒有(you)“完(wan)全(quan)(quan)充(chong)滿”，我們需(xu)要(yao)進(jin)行“完(wan)全(quan)(quan)充(chong)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)”（完(wan)全(quan)(quan)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)之后不間斷(duan)充(chong)12小(xiao)時(shi)(shi)至以(yi)上(shang)）益(yi)完(wan)全(quan)(quan)“開發”電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)“潛能”。這個(ge)完(wan)全(quan)(quan)充(chong)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)過程即稱為(wei)“激活電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)”，聯(lian)想Thinkpad等的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)管(guan)(guan)理軟(ruan)件有(you)一個(ge)“電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)標尺校準”功能原理類似。

個人覺得一些老科技的(de)(de)電池比(bi)如(ru)NiMH需(xu)(xu)要(yao)激(ji)活(huo)。鋰電池理論(lun)是需(xu)(xu)要(yao)激(ji)化因(yin)為需(xu)(xu)要(yao)在負極形(xing)成(cheng)一層SEI的(de)(de)保護層。但是這(zhe)個過程實際上已(yi)經在生產測試階(jie)段已(yi)經完成(cheng)啦。個人覺得消費者(zhe)對電池的(de)(de)誤區(qu)造成(cheng)有(you)這(zhe)樣的(de)(de)服務(wu)。

你的(de)手(shou)機電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)“餓(e)”死(si)了，開不了機充(chong)不進電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，這時需(xu)要激(ji)(ji)活(huo)！首先所謂餓(e)死(si)就(jiu)是(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)一(yi)直(zhi)沒電(dian)(dian)(dian)(dian)(dian)(dian)(dian)或者電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量很(hen)低時導致的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)無法(fa)再充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)現象。然后(hou)所謂激(ji)(ji)活(huo)目前有兩個辦法(fa):一(yi)是(shi)使(shi)用萬能(neng)充(chong)充(chong)個20分(fen)鐘(zhong)(zhong)左右就(jiu)可以(yi)激(ji)(ji)活(huo)。二是(shi)給手(shou)機維修店有較(jiao)為專業(ye)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓稍微高點的(de)比如12伏的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源來激(ji)(ji)活(huo)，具體(ti)就(jiu)是(shi)把(ba)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源正負極放在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)正負極幾十秒甚至幾分(fen)鐘(zhong)(zhong)給它通通電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，打通它！最后(hou)，激(ji)(ji)活(huo)后(hou)就(jiu)可以(yi)和原來一(yi)樣用直(zhi)充(chong)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)了，會不會對壽命有明顯影響(xiang)還(huan)不知道(dao)。

用儀器充電(dian)(dian)(dian)。（如果上(shang)述(shu)方式不(bu)行，電(dian)(dian)(dian)池(chi)也無故障，就需要用‘穩(wen)壓電(dian)(dian)(dian)源‘激活(huo)，黑色的線連電(dian)(dian)(dian)池(chi)負(fu)極，紅色的連電(dian)(dian)(dian)池(chi)正(zheng)極，充電(dian)(dian)(dian)電(dian)(dian)(dian)壓達(da)到(dao)3.8V，即可）使用鋰電(dian)(dian)(dian)池(chi)的裝置，第(di)一次使用不(bu)用充電(dian)(dian)(dian)12小時，這是沒必要的！
