如今電動車已經成為大家上下班的重要工具，而且幾年之后就要更換。因此遺留了不少電動車充電器。那這(zhe)些(xie)電(dian)(dian)動車充(chong)電(dian)(dian)器能(neng)否(fou)混用(yong)?如果有電(dian)(dian)動車標稱(cheng)電(dian)(dian)壓為48V的(de)電(dian)(dian)池(chi)組(zu)所配(pei)的(de)充(chong)電(dian)(dian)器，這(zhe)能(neng)否(fou)對標稱(cheng)電(dian)(dian)壓為60V的(de)電(dian)(dian)池(chi)組(zu)充(chong)電(dian)(dian)?這(zhe)是要(yao)分情況(kuang)討論(lun)的(de)：

　　1、如果標稱(cheng)電(dian)壓為60V的(de)(de)鉛(qian)酸(suan)蓄電(dian)池(chi)(chi)(chi)組完全放電(dian)、且手(shou)頭一時找不到配套的(de)(de)充電(dian)器，只有(you)48V的(de)(de)鉛(qian)酸(suan)蓄電(dian)池(chi)(chi)(chi)充電(dian)器，在(zai)輸出插頭和60V電(dian)池(chi)(chi)(chi)組充電(dian)孔插座極性一致(zhi)的(de)(de)條件下，是可以(yi)用來(lai)對60V電(dian)池(chi)(chi)(chi)組充電(dian)的(de)(de)。

　　因為(wei)60V電池組放電完(wan)畢后，電壓為(wei)10.5x5=52.5V，而48V充電器的(de)最高(gao)(gao)輸(shu)出電壓為(wei)14.4x4V，要比52.5V高(gao)(gao)。因此可以少(shao)量補充一些電的(de)。待電池組電壓上(shang)升到14.4x4V時，充電結(jie)束。

　　有(you)人說(shuo)(shuo)了，這還沒有(you)充滿嘛!有(you)什(shen)么用?這就說(shuo)(shuo)錯了：對于鉛(qian)(qian)酸(suan)蓄電池(chi)而言，放光電之(zhi)后如果不(bu)及時充電，正(zheng)、負極板上的(de)硫(liu)酸(suan)鉛(qian)(qian)就開(kai)始結晶——這就是鉛(qian)(qian)酸(suan)蓄電池(chi)的(de)癌癥(zheng)病灶!稱為(wei)硫(liu)化。隨著硫(liu)化的(de)不(bu)斷發展(zhan)，鉛(qian)(qian)酸(suan)蓄電池(chi)的(de)容量不(bu)斷下降，最終死(si)亡——報廢了。能在(zai)第一時間阻擊癌癥(zheng)，為(wei)什(shen)么不(bu)干?

　　2、如果60V電(dian)(dian)(dian)(dian)池(chi)組(zu)的(de)(de)兩(liang)端(duan)電(dian)(dian)(dian)(dian)壓(ya)，要大于(yu)等于(yu)48V充(chong)電(dian)(dian)(dian)(dian)器(qi)最高(gao)輸出(chu)電(dian)(dian)(dian)(dian)壓(ya)，用(yong)48V充(chong)電(dian)(dian)(dian)(dian)器(qi)，是不(bu)能(neng)對60V電(dian)(dian)(dian)(dian)池(chi)組(zu)充(chong)電(dian)(dian)(dian)(dian)的(de)(de)。因為充(chong)電(dian)(dian)(dian)(dian)是需要電(dian)(dian)(dian)(dian)位差的(de)(de)，電(dian)(dian)(dian)(dian)壓(ya)高(gao)的(de)(de)向電(dian)(dian)(dian)(dian)壓(ya)低(di)的(de)(de)才(cai)能(neng)充(chong)電(dian)(dian)(dian)(dian)的(de)(de)。不(bu)過(guo)你也不(bu)用(yong)擔心(xin)，電(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)壓(ya)高(gao)于(yu)充(chong)電(dian)(dian)(dian)(dian)器(qi)電(dian)(dian)(dian)(dian)壓(ya)時，電(dian)(dian)(dian)(dian)能(neng)會倒灌——充(chong)電(dian)(dian)(dian)(dian)器(qi)電(dian)(dian)(dian)(dian)路中，都(dou)設有防(fang)反接(jie)和倒充(chong)的(de)(de)二極管。

　　3、如果你有(you)動手能力的(de)話，可以(yi)拆(chai)開48V充(chong)電(dian)器(qi)，找到調整輸出電(dian)壓(ya)的(de)元件(如384x類(lei)充(chong)電(dian)器(qi)接光耦(ou)的(de)那個431)，調節431上的(de)分壓(ya)電(dian)阻阻值，就可以(yi)使充(chong)電(dian)器(qi)輸出電(dian)壓(ya)上升(sheng)或下降。

　　可(ke)以(yi)調節它，使(shi)(shi)輸出(chu)電壓為14Vx5左右，即可(ke)應急使(shi)(shi)用。不過(guo)需(xu)要注意，充(chong)電器(qi)次(ci)級濾(lv)波(bo)(bo)電容的耐壓值(48V充(chong)電器(qi)次(ci)級濾(lv)波(bo)(bo)電容的耐壓值多(duo)為63V)是否能承受了。最好更換為耐壓100V的。

　　另外還(huan)得(de)注意場效應管的(de)散熱問題和最大功耗問題(48V充電器多(duo)用(yong)8N60及以下的(de)，60V充電器多(duo)用(yong)12N60及以上(shang)的(de))。
