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)些電(dian)(dian)(dian)動(dong)車(che)充(chong)電(dian)(dian)(dian)器能否(fou)混用?如果有(you)電(dian)(dian)(dian)動(dong)車(che)標(biao)稱電(dian)(dian)(dian)壓為48V的(de)電(dian)(dian)(dian)池組所配的(de)充(chong)電(dian)(dian)(dian)器，這(zhe)能否(fou)對標(biao)稱電(dian)(dian)(dian)壓為60V的(de)電(dian)(dian)(dian)池組充(chong)電(dian)(dian)(dian)?這(zhe)是(shi)要分情(qing)況討(tao)論的(de)：

　　1、如果標稱電(dian)(dian)(dian)(dian)壓為60V的鉛酸(suan)蓄(xu)電(dian)(dian)(dian)(dian)池(chi)組(zu)(zu)完(wan)全放(fang)電(dian)(dian)(dian)(dian)、且手頭(tou)一(yi)時(shi)找(zhao)不到(dao)配套的充(chong)電(dian)(dian)(dian)(dian)器(qi)，只有48V的鉛酸(suan)蓄(xu)電(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)器(qi)，在輸出插(cha)頭(tou)和60V電(dian)(dian)(dian)(dian)池(chi)組(zu)(zu)充(chong)電(dian)(dian)(dian)(dian)孔插(cha)座極性一(yi)致的條(tiao)件下，是(shi)可(ke)以用來對60V電(dian)(dian)(dian)(dian)池(chi)組(zu)(zu)充(chong)電(dian)(dian)(dian)(dian)的。

　　因為60V電(dian)池組放(fang)電(dian)完畢后，電(dian)壓(ya)為10.5x5=52.5V，而48V充(chong)電(dian)器的最高(gao)輸出電(dian)壓(ya)為14.4x4V，要比(bi)52.5V高(gao)。因此可(ke)以少量補充(chong)一些電(dian)的。待電(dian)池組電(dian)壓(ya)上升到(dao)14.4x4V時(shi)，充(chong)電(dian)結束。

　　有人說(shuo)了，這(zhe)還(huan)沒有充(chong)滿嘛!有什么用?這(zhe)就說(shuo)錯了：對于鉛酸蓄電(dian)池而言，放光(guang)電(dian)之后如(ru)果不(bu)及(ji)時充(chong)電(dian)，正、負極板上的(de)硫(liu)酸鉛就開(kai)始結晶——這(zhe)就是(shi)鉛酸蓄電(dian)池的(de)癌癥病灶!稱為硫(liu)化。隨著硫(liu)化的(de)不(bu)斷發展，鉛酸蓄電(dian)池的(de)容量不(bu)斷下降，最終死亡——報廢了。能在(zai)第一時間阻擊癌癥，為什么不(bu)干(gan)?

　　2、如(ru)果60V電(dian)(dian)(dian)(dian)池組(zu)的(de)(de)(de)兩端電(dian)(dian)(dian)(dian)壓(ya)(ya)，要(yao)大于(yu)等于(yu)48V充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器最高輸出電(dian)(dian)(dian)(dian)壓(ya)(ya)，用(yong)48V充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器，是(shi)(shi)不(bu)能(neng)對(dui)60V電(dian)(dian)(dian)(dian)池組(zu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的(de)(de)(de)。因為充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)是(shi)(shi)需要(yao)電(dian)(dian)(dian)(dian)位差的(de)(de)(de)，電(dian)(dian)(dian)(dian)壓(ya)(ya)高的(de)(de)(de)向電(dian)(dian)(dian)(dian)壓(ya)(ya)低的(de)(de)(de)才能(neng)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的(de)(de)(de)。不(bu)過你也(ye)不(bu)用(yong)擔心(xin)，電(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)壓(ya)(ya)高于(yu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器電(dian)(dian)(dian)(dian)壓(ya)(ya)時，電(dian)(dian)(dian)(dian)能(neng)會倒(dao)灌(guan)——充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器電(dian)(dian)(dian)(dian)路中，都(dou)設有防反接和(he)倒(dao)充(chong)(chong)(chong)(chong)的(de)(de)(de)二(er)極管。

　　3、如(ru)果你(ni)有動手能(neng)力的話，可(ke)以拆開48V充(chong)電器(qi)(qi)，找到調整輸出(chu)電壓(ya)(ya)的元件(jian)(如(ru)384x類充(chong)電器(qi)(qi)接光耦的那(nei)個431)，調節(jie)431上的分壓(ya)(ya)電阻阻值(zhi)，就可(ke)以使(shi)充(chong)電器(qi)(qi)輸出(chu)電壓(ya)(ya)上升(sheng)或下(xia)降。

　　可(ke)以調節它，使輸出(chu)電(dian)(dian)壓(ya)(ya)為(wei)(wei)14Vx5左(zuo)右，即可(ke)應急(ji)使用。不過(guo)需要注意，充(chong)電(dian)(dian)器(qi)次(ci)級(ji)濾(lv)波電(dian)(dian)容(rong)的耐壓(ya)(ya)值(48V充(chong)電(dian)(dian)器(qi)次(ci)級(ji)濾(lv)波電(dian)(dian)容(rong)的耐壓(ya)(ya)值多(duo)為(wei)(wei)63V)是(shi)否能承受了。最好更換為(wei)(wei)耐壓(ya)(ya)100V的。

　　另外(wai)還得注意(yi)場效應管的(de)散熱問(wen)題(ti)和最大功耗(hao)問(wen)題(ti)(48V充電器(qi)多用8N60及(ji)以下的(de)，60V充電器(qi)多用12N60及(ji)以上的(de))。
