很多(duo)人有不(bu)(bu)好的(de)習慣，經常人不(bu)(bu)在家將電動車電池放(fang)(fang)車上(shang)，空氣(qi)開(kai)關也不(bu)(bu)關掉(diao)，放(fang)(fang)幾個月不(bu)(bu)騎。幾個月后(hou)再(zai)來騎行(xing)時(shi)就發現車子沒(mei)電而(er)且充(chong)電充(chong)不(bu)(bu)進(jin)去。充(chong)電器插上(shang)去，但是(shi)一(yi)直是(shi)綠(lv)燈，哪怕是(shi)24小時(shi)插著它也還是(shi)綠(lv)燈，因為(wei)電池電壓(ya)過低，與充(chong)電器輸(shu)出電壓(ya)相差過大的(de)話充(chong)電器是(shi)無法將電沖進(jin)電池的(de)。

這種(zhong)(zhong)情況(kuang)就是(shi)大家(jia)平常說的電(dian)(dian)池(chi)(chi)(chi)被“餓死”了。這種(zhong)(zhong)電(dian)(dian)池(chi)(chi)(chi)塊電(dian)(dian)池(chi)(chi)(chi)的電(dian)(dian)壓一(yi)般只(zhi)有(you)5.6V左右，不會(hui)超(chao)過6V。對于這樣的電(dian)(dian)池(chi)(chi)(chi)，大多數(shu)是(shi)換(huan)電(dian)(dian)池(chi)(chi)(chi)。但換(huan)一(yi)組電(dian)(dian)池(chi)(chi)(chi)好(hao)幾百(bai)，就這樣換(huan)掉有(you)點可惜，尤其是(shi)剛過保修的電(dian)(dian)池(chi)(chi)(chi)。

這(zhe)里介(jie)紹五種比(bi)較好(hao)的(de)方法，能(neng)將大(da)部(bu)分的(de)這(zhe)種“餓死(si)”的(de)電瓶拯救過來。注(zhu)意是大(da)部(bu)分不(bu)是百分百。

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(jin)行充(chong)(chong)電(dian)，這(zhe)樣的話是可(ke)以(yi)將(jiang)電(dian)充(chong)(chong)進(jin)去的，插(cha)上充(chong)(chong)電(dian)器(qi)之后(hou)(hou)，充(chong)(chong)電(dian)器(qi)是紅(hong)燈，此時可(ke)以(yi)將(jiang)電(dian)充(chong)(chong)進(jin)去。等充(chong)(chong)電(dian)器(qi)轉為綠燈，就把那塊另(ling)外(wai)串聯上去的電(dian)池拿掉。然后(hou)(hou)再正常充(chong)(chong)電(dian)就可(ke)以(yi)了。

二、并(bing)聯(lian)法。這種(zhong)(zhong)方法稍(shao)微麻煩一點。比如車輛(liang)原(yuan)來是(shi)48V-20AH的(de)(de)電(dian)(dian)池(chi)(chi)，我們(men)另外(wai)并(bing)聯(lian)一組，48V-20AH的(de)(de)電(dian)(dian)池(chi)(chi)。大家(jia)知道并(bing)聯(lian)電(dian)(dian)路各處的(de)(de)電(dian)(dian)壓(ya)是(shi)相等(deng)的(de)(de)，高的(de)(de)電(dian)(dian)壓(ya)端會(hui)向低的(de)(de)電(dian)(dian)壓(ya)端流入(ru)。這種(zhong)(zhong)方法也是(shi)很多電(dian)(dian)池(chi)(chi)經(jing)銷商在檢測完全沒有(you)電(dian)(dian)的(de)(de)電(dian)(dian)池(chi)(chi)所使(shi)用的(de)(de)方法。然(ran)后進(jin)行充(chong)電(dian)(dian)也可以(yi)達到充(chong)電(dian)(dian)的(de)(de)目的(de)(de)。這個(ge)原(yuan)理跟到，串聯(lian)一個(ge)電(dian)(dian)池(chi)(chi)，原(yuan)理差不多。也是(shi)將整組的(de)(de)電(dian)(dian)壓(ya)提升上去。

三、低壓充(chong)(chong)電(dian)(dian)法。選用小(xiao)一(yi)型號的(de)充(chong)(chong)電(dian)(dian)器進(jin)(jin)行(xing)充(chong)(chong)電(dian)(dian)。比如說是一(yi)組60V-20AH的(de)電(dian)(dian)池(chi)，那么我們(men)是用48V-20AH的(de)充(chong)(chong)電(dian)(dian)器進(jin)(jin)行(xing)充(chong)(chong)電(dian)(dian)。這樣大部分的(de)情況下(xia)，也是可以(yi)充(chong)(chong)進(jin)(jin)去的(de)。原理也是類似于(yu)第一(yi)種，將充(chong)(chong)電(dian)(dian)電(dian)(dian)壓與電(dian)(dian)池(chi)的(de)兩端電(dian)(dian)壓更接近。

四(si)、單塊電(dian)(dian)池(chi)充(chong)電(dian)(dian)法。將單塊電(dian)(dian)池(chi)用12伏(fu)的摩托(tuo)車充(chong)電(dian)(dian)器(qi)進行充(chong)電(dian)(dian)，可以將電(dian)(dian)池(chi)激活，但這種充(chong)電(dian)(dian)比較慢，一般要充(chong)7個小時以上，電(dian)(dian)池(chi)電(dian)(dian)壓才會緩慢回升到12V左右。如果全部單塊充(chong)很耗時間。

五、特殊充電器法。鋰電池充電器它是自動識別電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)壓的(de)，不管(guan)一組(zu)電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)壓有多(duo)少伏，都可(ke)以自動識別電(dian)(dian)(dian)壓，他(ta)都可(ke)以充(chong)電(dian)(dian)(dian)進去。比如原車(che)是60V-20AH的(de)電(dian)(dian)(dian)池(chi)，現在只有30V不到，它照(zhao)樣可(ke)以往(wang)里面充(chong)電(dian)(dian)(dian)的(de)。隨著電(dian)(dian)(dian)壓的(de)升(sheng)高，又全適應更(geng)高一階(jie)的(de)電(dian)(dian)(dian)壓，再給電(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)。臺鈴、綠(lv)佳電(dian)(dian)(dian)動車(che)、金彭(peng)三輪(lun)車(che)配套過(guo)這個品牌的(de)充(chong)電(dian)(dian)(dian)器。

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

電(dian)(dian)(dian)池(chi)(chi)激活(huo)在聯想電(dian)(dian)(dian)源(yuan)管理軟件(jian)上面叫做“電(dian)(dian)(dian)源(yuan)標尺(chi)校準(zhun)”。在PC端用Everest檢測(ce)電(dian)(dian)(dian)源(yuan)的(de)時(shi)(shi)候，有(you)一(yi)個(ge)“設計容量”，底(di)下緊(jin)跟(gen)著“完(wan)(wan)全充電(dian)(dian)(dian)容量”，如果兩項(xiang)的(de)數(shu)值(zhi)相同，則會看(kan)到(dao)再下邊的(de)“電(dian)(dian)(dian)池(chi)(chi)損耗"項(xiang)為0%；一(yi)般(ban)來(lai)說剛剛出廠的(de)或者(zhe)長時(shi)(shi)間(jian)放置(zhi)未及(ji)時(shi)(shi)保養的(de)電(dian)(dian)(dian)池(chi)(chi)”完(wan)(wan)全充電(dian)(dian)(dian)容量“會小于”設計容量“，此(ci)時(shi)(shi)就(jiu)會看(kan)到(dao)電(dian)(dian)(dian)池(chi)(chi)損耗是1%。也就(jiu)意味著電(dian)(dian)(dian)池(chi)(chi)沒有(you)“完(wan)(wan)全充滿”，我(wo)們需要進行“完(wan)(wan)全充放電(dian)(dian)(dian)”（完(wan)(wan)全放電(dian)(dian)(dian)之后不間(jian)斷(duan)充12小時(shi)(shi)至以(yi)上）益完(wan)(wan)全“開發(fa)”電(dian)(dian)(dian)池(chi)(chi)的(de)“潛能”。這個(ge)完(wan)(wan)全充放電(dian)(dian)(dian)的(de)過程即稱為“激活(huo)電(dian)(dian)(dian)池(chi)(chi)”，聯想Thinkpad等的(de)電(dian)(dian)(dian)源(yuan)管理軟件(jian)有(you)一(yi)個(ge)“電(dian)(dian)(dian)源(yuan)標尺(chi)校準(zhun)”功(gong)能原(yuan)理類(lei)似。

個(ge)人覺(jue)得(de)一(yi)些(xie)老科技的(de)(de)電池(chi)比如NiMH需(xu)要激活。鋰電池(chi)理(li)論是需(xu)要激化因(yin)為(wei)需(xu)要在負極(ji)形成(cheng)一(yi)層(ceng)SEI的(de)(de)保護層(ceng)。但是這個(ge)過(guo)程實(shi)際上已(yi)經在生產測試階(jie)段已(yi)經完成(cheng)啦。個(ge)人覺(jue)得(de)消費者對電池(chi)的(de)(de)誤區造成(cheng)有這樣(yang)的(de)(de)服務。

你的手機電(dian)池(chi)“餓”死了，開不(bu)(bu)了機充(chong)(chong)(chong)不(bu)(bu)進電(dian)，這時需要激(ji)(ji)活！首先所(suo)謂餓死就(jiu)是電(dian)池(chi)一(yi)直沒電(dian)或者電(dian)量很低(di)時導致(zhi)的電(dian)池(chi)無法再充(chong)(chong)(chong)電(dian)的現象。然后所(suo)謂激(ji)(ji)活目前(qian)有(you)(you)兩(liang)個辦法:一(yi)是使用萬能充(chong)(chong)(chong)充(chong)(chong)(chong)個20分鐘左右就(jiu)可以激(ji)(ji)活。二是給(gei)(gei)手機維修店有(you)(you)較為專業的電(dian)壓稍(shao)微高點的比如12伏的電(dian)源來激(ji)(ji)活，具(ju)體就(jiu)是把電(dian)源正負(fu)極放在電(dian)池(chi)正負(fu)極幾(ji)十秒甚至幾(ji)分鐘給(gei)(gei)它通通電(dian)，打通它！最后，激(ji)(ji)活后就(jiu)可以和(he)原來一(yi)樣用直充(chong)(chong)(chong)充(chong)(chong)(chong)電(dian)了，會不(bu)(bu)會對壽命有(you)(you)明顯影響(xiang)還不(bu)(bu)知道。

用(yong)儀器充電(dian)。（如果上述方式不行(xing)，電(dian)池(chi)也無(wu)故障(zhang)，就需要(yao)用(yong)‘穩(wen)壓電(dian)源‘激活(huo)，黑(hei)色的(de)線連(lian)電(dian)池(chi)負極，紅(hong)色的(de)連(lian)電(dian)池(chi)正極，充電(dian)電(dian)壓達到(dao)3.8V，即可(ke)）使用(yong)鋰電(dian)池(chi)的(de)裝置，第一(yi)次使用(yong)不用(yong)充電(dian)12小時，這是沒必要(yao)的(de)！
