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。那這些電(dian)(dian)(dian)(dian)動車充電(dian)(dian)(dian)(dian)器(qi)能否混用(yong)?如果有電(dian)(dian)(dian)(dian)動車標稱電(dian)(dian)(dian)(dian)壓(ya)為48V的(de)電(dian)(dian)(dian)(dian)池組(zu)所配的(de)充電(dian)(dian)(dian)(dian)器(qi)，這能否對(dui)標稱電(dian)(dian)(dian)(dian)壓(ya)為60V的(de)電(dian)(dian)(dian)(dian)池組(zu)充電(dian)(dian)(dian)(dian)?這是(shi)要(yao)分情況討論的(de)：

　　1、如(ru)果(guo)標稱電(dian)(dian)壓(ya)為60V的(de)鉛(qian)酸蓄電(dian)(dian)池組(zu)完(wan)全放(fang)電(dian)(dian)、且手頭一(yi)時找不(bu)到配(pei)套(tao)的(de)充(chong)電(dian)(dian)器，只有48V的(de)鉛(qian)酸蓄電(dian)(dian)池充(chong)電(dian)(dian)器，在(zai)輸出插頭和60V電(dian)(dian)池組(zu)充(chong)電(dian)(dian)孔插座極性一(yi)致的(de)條件(jian)下，是可(ke)以用來對60V電(dian)(dian)池組(zu)充(chong)電(dian)(dian)的(de)。

　　因(yin)(yin)為(wei)60V電(dian)池組(zu)放(fang)電(dian)完(wan)畢后，電(dian)壓為(wei)10.5x5=52.5V，而48V充(chong)電(dian)器的最高輸出電(dian)壓為(wei)14.4x4V，要比52.5V高。因(yin)(yin)此可以少量(liang)補充(chong)一些(xie)電(dian)的。待電(dian)池組(zu)電(dian)壓上升到14.4x4V時，充(chong)電(dian)結束。

　　有(you)人(ren)說(shuo)了，這還沒有(you)充滿嘛!有(you)什么(me)用?這就(jiu)說(shuo)錯了：對于鉛(qian)(qian)酸(suan)蓄(xu)電(dian)池而言(yan)，放(fang)光電(dian)之后如(ru)果不及時充電(dian)，正、負(fu)極板上(shang)的硫(liu)酸(suan)鉛(qian)(qian)就(jiu)開始結晶——這就(jiu)是(shi)鉛(qian)(qian)酸(suan)蓄(xu)電(dian)池的癌(ai)癥病灶!稱(cheng)為硫(liu)化。隨著(zhu)硫(liu)化的不斷發展，鉛(qian)(qian)酸(suan)蓄(xu)電(dian)池的容量不斷下(xia)降，最終死(si)亡——報廢了。能在第一(yi)時間阻擊癌(ai)癥，為什么(me)不干?

　　2、如果(guo)60V電(dian)(dian)(dian)(dian)池組的(de)(de)兩(liang)端電(dian)(dian)(dian)(dian)壓(ya)，要(yao)大于(yu)等于(yu)48V充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器最高輸出(chu)電(dian)(dian)(dian)(dian)壓(ya)，用48V充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器，是(shi)不(bu)能(neng)對60V電(dian)(dian)(dian)(dian)池組充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的(de)(de)。因(yin)為充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)是(shi)需(xu)要(yao)電(dian)(dian)(dian)(dian)位差的(de)(de)，電(dian)(dian)(dian)(dian)壓(ya)高的(de)(de)向電(dian)(dian)(dian)(dian)壓(ya)低的(de)(de)才能(neng)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的(de)(de)。不(bu)過(guo)你也不(bu)用擔心(xin)，電(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)壓(ya)高于(yu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器電(dian)(dian)(dian)(dian)壓(ya)時，電(dian)(dian)(dian)(dian)能(neng)會倒灌(guan)——充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器電(dian)(dian)(dian)(dian)路中，都設有防反(fan)接(jie)和倒充(chong)(chong)(chong)(chong)的(de)(de)二極管。

　　3、如(ru)果你有動手(shou)能力(li)的話，可以(yi)拆開48V充電器(qi)，找(zhao)到調整輸出(chu)電壓(ya)的元件(如(ru)384x類充電器(qi)接光(guang)耦的那個431)，調節431上的分(fen)壓(ya)電阻阻值，就可以(yi)使充電器(qi)輸出(chu)電壓(ya)上升(sheng)或下降(jiang)。

　　可(ke)以調(diao)節它(ta)，使輸出電(dian)(dian)(dian)壓(ya)為(wei)14Vx5左(zuo)右，即可(ke)應(ying)急使用。不過需要注(zhu)意(yi)，充電(dian)(dian)(dian)器次級(ji)濾波電(dian)(dian)(dian)容(rong)(rong)的耐(nai)壓(ya)值(48V充電(dian)(dian)(dian)器次級(ji)濾波電(dian)(dian)(dian)容(rong)(rong)的耐(nai)壓(ya)值多為(wei)63V)是(shi)否能承(cheng)受了。最好更換為(wei)耐(nai)壓(ya)100V的。

　　另外還得注(zhu)意場效應管的散熱(re)問題和(he)最大功(gong)耗問題(48V充(chong)電器多(duo)用8N60及以下的，60V充(chong)電器多(duo)用12N60及以上的)。
