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(dong)車(che)充(chong)(chong)電(dian)(dian)器(qi)能(neng)否(fou)混用(yong)?如果有電(dian)(dian)動(dong)車(che)標稱電(dian)(dian)壓為(wei)48V的(de)(de)電(dian)(dian)池(chi)組(zu)所配的(de)(de)充(chong)(chong)電(dian)(dian)器(qi)，這(zhe)能(neng)否(fou)對(dui)標稱電(dian)(dian)壓為(wei)60V的(de)(de)電(dian)(dian)池(chi)組(zu)充(chong)(chong)電(dian)(dian)?這(zhe)是(shi)要分(fen)情(qing)況(kuang)討(tao)論的(de)(de)：

　　1、如果標稱電(dian)(dian)壓為60V的(de)鉛(qian)酸蓄電(dian)(dian)池(chi)(chi)組(zu)完全放電(dian)(dian)、且手頭(tou)一時(shi)找(zhao)不到配套的(de)充(chong)(chong)電(dian)(dian)器，只有48V的(de)鉛(qian)酸蓄電(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)器，在輸出插頭(tou)和60V電(dian)(dian)池(chi)(chi)組(zu)充(chong)(chong)電(dian)(dian)孔插座(zuo)極性(xing)一致的(de)條件下，是可以用來對60V電(dian)(dian)池(chi)(chi)組(zu)充(chong)(chong)電(dian)(dian)的(de)。

　　因為60V電(dian)池組放電(dian)完畢(bi)后，電(dian)壓為10.5x5=52.5V，而48V充(chong)電(dian)器的最高輸(shu)出電(dian)壓為14.4x4V，要(yao)比52.5V高。因此可以少量補充(chong)一些電(dian)的。待電(dian)池組電(dian)壓上升到14.4x4V時(shi)，充(chong)電(dian)結束。

　　有人(ren)說了(le)，這(zhe)還沒有充(chong)滿嘛!有什么用?這(zhe)就說錯了(le)：對(dui)于(yu)鉛酸(suan)蓄電池(chi)而(er)言(yan)，放光電之后如果不(bu)及時充(chong)電，正(zheng)、負極板(ban)上的(de)硫(liu)酸(suan)鉛就開(kai)始結晶(jing)——這(zhe)就是鉛酸(suan)蓄電池(chi)的(de)癌癥(zheng)病(bing)灶!稱(cheng)為(wei)硫(liu)化(hua)。隨著硫(liu)化(hua)的(de)不(bu)斷發(fa)展，鉛酸(suan)蓄電池(chi)的(de)容(rong)量不(bu)斷下降(jiang)，最終死亡——報(bao)廢(fei)了(le)。能在第(di)一時間阻擊癌癥(zheng)，為(wei)什么不(bu)干?

　　2、如(ru)果60V電(dian)(dian)(dian)(dian)池(chi)組的(de)(de)(de)兩端電(dian)(dian)(dian)(dian)壓(ya)，要(yao)大于等于48V充(chong)電(dian)(dian)(dian)(dian)器(qi)最高輸出電(dian)(dian)(dian)(dian)壓(ya)，用48V充(chong)電(dian)(dian)(dian)(dian)器(qi)，是不能(neng)對(dui)60V電(dian)(dian)(dian)(dian)池(chi)組充(chong)電(dian)(dian)(dian)(dian)的(de)(de)(de)。因為充(chong)電(dian)(dian)(dian)(dian)是需要(yao)電(dian)(dian)(dian)(dian)位(wei)差(cha)的(de)(de)(de)，電(dian)(dian)(dian)(dian)壓(ya)高的(de)(de)(de)向電(dian)(dian)(dian)(dian)壓(ya)低的(de)(de)(de)才能(neng)充(chong)電(dian)(dian)(dian)(dian)的(de)(de)(de)。不過(guo)你(ni)也不用擔心，電(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)壓(ya)高于充(chong)電(dian)(dian)(dian)(dian)器(qi)電(dian)(dian)(dian)(dian)壓(ya)時(shi)，電(dian)(dian)(dian)(dian)能(neng)會倒(dao)灌——充(chong)電(dian)(dian)(dian)(dian)器(qi)電(dian)(dian)(dian)(dian)路中，都設有防反(fan)接和倒(dao)充(chong)的(de)(de)(de)二極管。

　　3、如果(guo)你有(you)動手(shou)能(neng)力的話(hua)，可(ke)以(yi)(yi)拆開48V充(chong)電(dian)器，找到調(diao)整(zheng)輸出電(dian)壓(ya)的元件(如384x類充(chong)電(dian)器接光耦的那個431)，調(diao)節431上的分壓(ya)電(dian)阻阻值，就可(ke)以(yi)(yi)使充(chong)電(dian)器輸出電(dian)壓(ya)上升或下降。

　　可以調(diao)節(jie)它，使輸出(chu)電(dian)壓(ya)為(wei)14Vx5左右，即可應急使用。不過需要注意，充電(dian)器次(ci)級濾波電(dian)容的耐(nai)壓(ya)值(48V充電(dian)器次(ci)級濾波電(dian)容的耐(nai)壓(ya)值多為(wei)63V)是否(fou)能(neng)承受了(le)。最好更(geng)換為(wei)耐(nai)壓(ya)100V的。

　　另(ling)外還得(de)注意(yi)場效應管的散熱問題和最大功耗問題(48V充電器多(duo)用8N60及以下的，60V充電器多(duo)用12N60及以上(shang)的)。
