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)動(dong)車充(chong)電(dian)(dian)器能否混用?如果有電(dian)(dian)動(dong)車標稱(cheng)電(dian)(dian)壓為48V的(de)(de)電(dian)(dian)池組(zu)所配的(de)(de)充(chong)電(dian)(dian)器，這能否對標稱(cheng)電(dian)(dian)壓為60V的(de)(de)電(dian)(dian)池組(zu)充(chong)電(dian)(dian)?這是要分(fen)情況討(tao)論(lun)的(de)(de)：

　　1、如(ru)果標稱(cheng)電(dian)(dian)(dian)壓為(wei)60V的(de)鉛酸蓄(xu)電(dian)(dian)(dian)池(chi)組完全放電(dian)(dian)(dian)、且手頭一(yi)時找不到(dao)配套的(de)充(chong)(chong)電(dian)(dian)(dian)器(qi)，只有48V的(de)鉛酸蓄(xu)電(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)器(qi)，在輸(shu)出插頭和(he)60V電(dian)(dian)(dian)池(chi)組充(chong)(chong)電(dian)(dian)(dian)孔插座(zuo)極性一(yi)致的(de)條件下，是可以用來(lai)對60V電(dian)(dian)(dian)池(chi)組充(chong)(chong)電(dian)(dian)(dian)的(de)。

　　因(yin)為(wei)60V電(dian)(dian)(dian)池組放電(dian)(dian)(dian)完畢后(hou)，電(dian)(dian)(dian)壓為(wei)10.5x5=52.5V，而48V充電(dian)(dian)(dian)器的最高(gao)輸出電(dian)(dian)(dian)壓為(wei)14.4x4V，要比(bi)52.5V高(gao)。因(yin)此可(ke)以少量補(bu)充一(yi)些電(dian)(dian)(dian)的。待電(dian)(dian)(dian)池組電(dian)(dian)(dian)壓上升到14.4x4V時，充電(dian)(dian)(dian)結束。

　　有人說了(le)，這還沒有充滿嘛!有什(shen)么用?這就(jiu)說錯了(le)：對于鉛(qian)酸(suan)蓄電(dian)池而言，放光電(dian)之(zhi)后如果不(bu)及時充電(dian)，正、負極板上的硫酸(suan)鉛(qian)就(jiu)開始(shi)結晶——這就(jiu)是鉛(qian)酸(suan)蓄電(dian)池的癌癥病灶!稱為(wei)硫化(hua)。隨著硫化(hua)的不(bu)斷發展，鉛(qian)酸(suan)蓄電(dian)池的容量不(bu)斷下降，最終死亡(wang)——報廢了(le)。能(neng)在(zai)第一(yi)時間阻(zu)擊癌癥，為(wei)什(shen)么不(bu)干?

　　2、如果60V電(dian)(dian)(dian)(dian)池(chi)(chi)組(zu)(zu)的兩端電(dian)(dian)(dian)(dian)壓(ya)，要大于等于48V充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)最高(gao)輸出電(dian)(dian)(dian)(dian)壓(ya)，用48V充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)，是不(bu)能對60V電(dian)(dian)(dian)(dian)池(chi)(chi)組(zu)(zu)充(chong)(chong)電(dian)(dian)(dian)(dian)的。因為(wei)充(chong)(chong)電(dian)(dian)(dian)(dian)是需要電(dian)(dian)(dian)(dian)位差的，電(dian)(dian)(dian)(dian)壓(ya)高(gao)的向電(dian)(dian)(dian)(dian)壓(ya)低的才能充(chong)(chong)電(dian)(dian)(dian)(dian)的。不(bu)過你(ni)也不(bu)用擔心，電(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)壓(ya)高(gao)于充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)電(dian)(dian)(dian)(dian)壓(ya)時，電(dian)(dian)(dian)(dian)能會倒灌——充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)電(dian)(dian)(dian)(dian)路中(zhong)，都設有防(fang)反接和倒充(chong)(chong)的二極管。

　　3、如(ru)果(guo)你有動手能力(li)的(de)話，可以拆開48V充電(dian)器，找到(dao)調整(zheng)輸出(chu)電(dian)壓的(de)元件(如(ru)384x類充電(dian)器接光(guang)耦的(de)那個431)，調節431上(shang)的(de)分壓電(dian)阻阻值，就可以使充電(dian)器輸出(chu)電(dian)壓上(shang)升或下降。

　　可以(yi)調節它(ta)，使輸出(chu)電(dian)(dian)壓(ya)為(wei)14Vx5左(zuo)右(you)，即(ji)可應急(ji)使用。不過(guo)需要注意，充電(dian)(dian)器次(ci)級濾(lv)波(bo)電(dian)(dian)容的(de)耐壓(ya)值(zhi)(48V充電(dian)(dian)器次(ci)級濾(lv)波(bo)電(dian)(dian)容的(de)耐壓(ya)值(zhi)多為(wei)63V)是否能(neng)承受了。最好(hao)更換(huan)為(wei)耐壓(ya)100V的(de)。

　　另(ling)外還得注意(yi)場效應管的散熱問題和最(zui)大(da)功耗(hao)問題(48V充(chong)電(dian)器多用8N60及(ji)以(yi)下的，60V充(chong)電(dian)器多用12N60及(ji)以(yi)上的)。
