很(hen)多人有不好(hao)的(de)習(xi)慣，經常人不在(zai)家將(jiang)電動車電池(chi)放車上(shang)，空氣開關也不關掉，放幾個月(yue)不騎。幾個月(yue)后再來騎行時就(jiu)發現車子沒電而(er)且(qie)充(chong)電充(chong)不進去。充(chong)電器(qi)(qi)插上(shang)去，但是(shi)一直是(shi)綠(lv)燈，哪(na)怕(pa)是(shi)24小時插著它也還是(shi)綠(lv)燈，因為(wei)電池(chi)電壓過低，與充(chong)電器(qi)(qi)輸出電壓相差過大的(de)話充(chong)電器(qi)(qi)是(shi)無法將(jiang)電沖進電池(chi)的(de)。

這(zhe)種情況(kuang)就是大家平常說的電(dian)池(chi)(chi)被“餓死”了(le)。這(zhe)種電(dian)池(chi)(chi)塊(kuai)電(dian)池(chi)(chi)的電(dian)壓一般只(zhi)有5.6V左右(you)，不會超過6V。對于這(zhe)樣(yang)的電(dian)池(chi)(chi)，大多(duo)數(shu)是換電(dian)池(chi)(chi)。但換一組電(dian)池(chi)(chi)好幾百，就這(zhe)樣(yang)換掉(diao)有點可惜(xi)，尤其是剛過保修的電(dian)池(chi)(chi)。

這里介紹(shao)五(wu)種比較好的(de)方法，能將大部分(fen)的(de)這種“餓死”的(de)電瓶拯救(jiu)過來(lai)。注(zhu)意是(shi)大部分(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)，這(zhe)樣的話是可以(yi)(yi)將電(dian)充進去的，插上充電(dian)器(qi)之后，充電(dian)器(qi)是紅(hong)燈，此時可以(yi)(yi)將電(dian)充進去。等充電(dian)器(qi)轉為綠燈，就(jiu)把那塊(kuai)另外(wai)串聯上去的電(dian)池拿掉。然后再正常充電(dian)就(jiu)可以(yi)(yi)了。

二、并聯法(fa)。這種方(fang)(fang)法(fa)稍(shao)微麻煩一(yi)點。比如車輛原(yuan)來是(shi)(shi)48V-20AH的(de)(de)(de)電(dian)(dian)(dian)池，我們另(ling)外并聯一(yi)組，48V-20AH的(de)(de)(de)電(dian)(dian)(dian)池。大家知道并聯電(dian)(dian)(dian)路各(ge)處的(de)(de)(de)電(dian)(dian)(dian)壓是(shi)(shi)相等的(de)(de)(de)，高的(de)(de)(de)電(dian)(dian)(dian)壓端會向低的(de)(de)(de)電(dian)(dian)(dian)壓端流入。這種方(fang)(fang)法(fa)也是(shi)(shi)很多電(dian)(dian)(dian)池經銷商在檢測完全(quan)沒有(you)電(dian)(dian)(dian)的(de)(de)(de)電(dian)(dian)(dian)池所使用(yong)的(de)(de)(de)方(fang)(fang)法(fa)。然后進(jin)行充(chong)電(dian)(dian)(dian)也可以達到充(chong)電(dian)(dian)(dian)的(de)(de)(de)目的(de)(de)(de)。這個(ge)原(yuan)理跟(gen)到，串聯一(yi)個(ge)電(dian)(dian)(dian)池，原(yuan)理差不多。也是(shi)(shi)將整組的(de)(de)(de)電(dian)(dian)(dian)壓提(ti)升上去。

三、低壓充(chong)(chong)電(dian)(dian)法(fa)。選用(yong)(yong)小一型號的(de)充(chong)(chong)電(dian)(dian)器(qi)進行充(chong)(chong)電(dian)(dian)。比如說是一組(zu)60V-20AH的(de)電(dian)(dian)池(chi)，那(nei)么我(wo)們是用(yong)(yong)48V-20AH的(de)充(chong)(chong)電(dian)(dian)器(qi)進行充(chong)(chong)電(dian)(dian)。這(zhe)樣大(da)部(bu)分的(de)情況下，也是可以充(chong)(chong)進去的(de)。原(yuan)理也是類似于第(di)一種，將充(chong)(chong)電(dian)(dian)電(dian)(dian)壓與(yu)電(dian)(dian)池(chi)的(de)兩端電(dian)(dian)壓更接近。

四(si)、單塊電(dian)(dian)池充(chong)(chong)電(dian)(dian)法。將單塊電(dian)(dian)池用12伏的(de)摩托車充(chong)(chong)電(dian)(dian)器(qi)進(jin)行充(chong)(chong)電(dian)(dian)，可以(yi)將電(dian)(dian)池激(ji)活，但這(zhe)種充(chong)(chong)電(dian)(dian)比較(jiao)慢，一般要充(chong)(chong)7個小時(shi)(shi)以(yi)上，電(dian)(dian)池電(dian)(dian)壓才會(hui)緩慢回升到12V左右。如(ru)果全部單塊充(chong)(chong)很耗時(shi)(shi)間。

五、特殊充電器法。鋰電池充電器它是(shi)自動(dong)識(shi)別電(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)壓(ya)的(de)，不管一組電(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)壓(ya)有多少伏，都可以(yi)自動(dong)識(shi)別電(dian)(dian)(dian)壓(ya)，他都可以(yi)充電(dian)(dian)(dian)進去(qu)。比如原車(che)是(shi)60V-20AH的(de)電(dian)(dian)(dian)池(chi)(chi)，現在(zai)只(zhi)有30V不到，它照樣可以(yi)往里面(mian)充電(dian)(dian)(dian)的(de)。隨著電(dian)(dian)(dian)壓(ya)的(de)升高，又全適應更高一階的(de)電(dian)(dian)(dian)壓(ya)，再給(gei)電(dian)(dian)(dian)池(chi)(chi)充電(dian)(dian)(dian)。臺鈴、綠佳電(dian)(dian)(dian)動(dong)車(che)、金彭(peng)三輪車(che)配套過這個品牌的(de)充電(dian)(dian)(dian)器。

另(ling)外普及下鋰電(dian)(dian)池(chi)“餓死了(le)”怎么激活？筆記(ji)本電(dian)(dian)池(chi)或者手機電(dian)(dian)池(chi)

電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)激活在聯想(xiang)電(dian)(dian)(dian)(dian)源(yuan)管理(li)(li)軟件(jian)上(shang)面(mian)叫做“電(dian)(dian)(dian)(dian)源(yuan)標尺校(xiao)準(zhun)”。在PC端用Everest檢測電(dian)(dian)(dian)(dian)源(yuan)的(de)時(shi)候，有一個(ge)“設計(ji)(ji)容量”，底(di)下緊跟著“完全(quan)(quan)充電(dian)(dian)(dian)(dian)容量”，如(ru)果兩項(xiang)的(de)數(shu)值相同，則會(hui)看到(dao)再(zai)下邊的(de)“電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)損(sun)(sun)耗"項(xiang)為0%；一般(ban)來(lai)說剛剛出(chu)廠的(de)或者長時(shi)間(jian)放(fang)置未及時(shi)保養(yang)的(de)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)”完全(quan)(quan)充電(dian)(dian)(dian)(dian)容量“會(hui)小(xiao)于”設計(ji)(ji)容量“，此時(shi)就會(hui)看到(dao)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)損(sun)(sun)耗是1%。也就意味著電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)沒有“完全(quan)(quan)充滿”，我們需要進行(xing)“完全(quan)(quan)充放(fang)電(dian)(dian)(dian)(dian)”（完全(quan)(quan)放(fang)電(dian)(dian)(dian)(dian)之后(hou)不間(jian)斷充12小(xiao)時(shi)至以上(shang)）益(yi)完全(quan)(quan)“開發”電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)“潛能”。這個(ge)完全(quan)(quan)充放(fang)電(dian)(dian)(dian)(dian)的(de)過(guo)程(cheng)即(ji)稱為“激活電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)”，聯想(xiang)Thinkpad等的(de)電(dian)(dian)(dian)(dian)源(yuan)管理(li)(li)軟件(jian)有一個(ge)“電(dian)(dian)(dian)(dian)源(yuan)標尺校(xiao)準(zhun)”功能原理(li)(li)類似。

個人(ren)覺得(de)(de)一些老科(ke)技的(de)(de)電(dian)池(chi)(chi)比如(ru)NiMH需要(yao)激活。鋰電(dian)池(chi)(chi)理論(lun)是需要(yao)激化因(yin)為需要(yao)在(zai)負極形成(cheng)一層SEI的(de)(de)保護層。但是這個過程實際上已經在(zai)生產測(ce)試階段已經完成(cheng)啦(la)。個人(ren)覺得(de)(de)消費者對電(dian)池(chi)(chi)的(de)(de)誤區造成(cheng)有(you)這樣的(de)(de)服務。

你的(de)手機電(dian)(dian)(dian)(dian)池“餓”死(si)了，開不(bu)了機充(chong)(chong)不(bu)進(jin)電(dian)(dian)(dian)(dian)，這(zhe)時需要激(ji)(ji)活！首先所(suo)謂(wei)餓死(si)就(jiu)是(shi)(shi)電(dian)(dian)(dian)(dian)池一直沒電(dian)(dian)(dian)(dian)或者電(dian)(dian)(dian)(dian)量很低時導致的(de)電(dian)(dian)(dian)(dian)池無(wu)法(fa)再充(chong)(chong)電(dian)(dian)(dian)(dian)的(de)現象。然后(hou)所(suo)謂(wei)激(ji)(ji)活目前有兩個辦法(fa):一是(shi)(shi)使(shi)用萬能充(chong)(chong)充(chong)(chong)個20分鐘左右就(jiu)可以(yi)激(ji)(ji)活。二是(shi)(shi)給(gei)手機維修(xiu)店有較(jiao)為專業(ye)的(de)電(dian)(dian)(dian)(dian)壓稍微高(gao)點的(de)比(bi)如12伏的(de)電(dian)(dian)(dian)(dian)源來激(ji)(ji)活，具體就(jiu)是(shi)(shi)把電(dian)(dian)(dian)(dian)源正負極放(fang)在電(dian)(dian)(dian)(dian)池正負極幾十秒甚(shen)至幾分鐘給(gei)它通(tong)通(tong)電(dian)(dian)(dian)(dian)，打(da)通(tong)它！最后(hou)，激(ji)(ji)活后(hou)就(jiu)可以(yi)和(he)原來一樣用直充(chong)(chong)充(chong)(chong)電(dian)(dian)(dian)(dian)了，會不(bu)會對壽命有明顯影(ying)響還不(bu)知道。

用儀(yi)器充(chong)電(dian)。（如果上(shang)述方式不行，電(dian)池(chi)也無故障，就需要用‘穩壓電(dian)源‘激活，黑色(se)的(de)線連電(dian)池(chi)負極(ji)，紅(hong)色(se)的(de)連電(dian)池(chi)正(zheng)極(ji)，充(chong)電(dian)電(dian)壓達到3.8V，即可）使用鋰電(dian)池(chi)的(de)裝置，第一次(ci)使用不用充(chong)電(dian)12小時，這是(shi)沒必要的(de)！
