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)動車充電(dian)(dian)(dian)器(qi)能否混用?如果有(you)電(dian)(dian)(dian)動車標稱(cheng)電(dian)(dian)(dian)壓為48V的(de)(de)電(dian)(dian)(dian)池(chi)組所配的(de)(de)充電(dian)(dian)(dian)器(qi)，這能否對標稱(cheng)電(dian)(dian)(dian)壓為60V的(de)(de)電(dian)(dian)(dian)池(chi)組充電(dian)(dian)(dian)?這是要分情況討論的(de)(de)：

　　1、如果(guo)標稱(cheng)電(dian)(dian)(dian)壓為60V的(de)(de)鉛酸蓄電(dian)(dian)(dian)池組完全放電(dian)(dian)(dian)、且手頭一(yi)時(shi)找不到(dao)配套的(de)(de)充(chong)電(dian)(dian)(dian)器，只有(you)48V的(de)(de)鉛酸蓄電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)器，在輸出插(cha)頭和60V電(dian)(dian)(dian)池組充(chong)電(dian)(dian)(dian)孔插(cha)座(zuo)極性一(yi)致的(de)(de)條件下(xia)，是可(ke)以用來對60V電(dian)(dian)(dian)池組充(chong)電(dian)(dian)(dian)的(de)(de)。

　　因為(wei)60V電(dian)(dian)池(chi)組放電(dian)(dian)完(wan)畢后，電(dian)(dian)壓(ya)為(wei)10.5x5=52.5V，而48V充(chong)(chong)(chong)電(dian)(dian)器的(de)最高(gao)輸出電(dian)(dian)壓(ya)為(wei)14.4x4V，要比52.5V高(gao)。因此可以少量補充(chong)(chong)(chong)一些電(dian)(dian)的(de)。待電(dian)(dian)池(chi)組電(dian)(dian)壓(ya)上升到14.4x4V時(shi)，充(chong)(chong)(chong)電(dian)(dian)結束。

　　有(you)人(ren)說了，這(zhe)還(huan)沒有(you)充滿嘛!有(you)什(shen)么(me)用?這(zhe)就說錯了：對于鉛(qian)酸(suan)(suan)蓄電(dian)池而言，放光電(dian)之(zhi)后如果不(bu)及時(shi)充電(dian)，正、負極(ji)板上的硫酸(suan)(suan)鉛(qian)就開始結晶——這(zhe)就是鉛(qian)酸(suan)(suan)蓄電(dian)池的癌癥病灶!稱為(wei)硫化。隨著硫化的不(bu)斷(duan)發展，鉛(qian)酸(suan)(suan)蓄電(dian)池的容量不(bu)斷(duan)下降(jiang)，最終死亡——報廢了。能(neng)在第(di)一(yi)時(shi)間阻(zu)擊癌癥，為(wei)什(shen)么(me)不(bu)干(gan)?

　　2、如(ru)果60V電(dian)(dian)(dian)(dian)(dian)池組的(de)(de)兩端電(dian)(dian)(dian)(dian)(dian)壓(ya)，要大于等于48V充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)最(zui)高輸出電(dian)(dian)(dian)(dian)(dian)壓(ya)，用(yong)48V充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)，是(shi)不(bu)(bu)(bu)能(neng)對60V電(dian)(dian)(dian)(dian)(dian)池組充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)的(de)(de)。因為充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)是(shi)需要電(dian)(dian)(dian)(dian)(dian)位差(cha)的(de)(de)，電(dian)(dian)(dian)(dian)(dian)壓(ya)高的(de)(de)向(xiang)電(dian)(dian)(dian)(dian)(dian)壓(ya)低的(de)(de)才(cai)能(neng)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)的(de)(de)。不(bu)(bu)(bu)過你也不(bu)(bu)(bu)用(yong)擔心，電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)壓(ya)高于充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)電(dian)(dian)(dian)(dian)(dian)壓(ya)時，電(dian)(dian)(dian)(dian)(dian)能(neng)會(hui)倒灌——充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)電(dian)(dian)(dian)(dian)(dian)路中，都設有防反接(jie)和倒充(chong)(chong)(chong)的(de)(de)二極(ji)管。

　　3、如(ru)(ru)果(guo)你有動手能(neng)力的(de)話(hua)，可以(yi)拆(chai)開48V充(chong)電(dian)(dian)器，找(zhao)到(dao)調(diao)整輸出電(dian)(dian)壓(ya)的(de)元件(jian)(如(ru)(ru)384x類充(chong)電(dian)(dian)器接光耦的(de)那(nei)個431)，調(diao)節(jie)431上的(de)分壓(ya)電(dian)(dian)阻(zu)阻(zu)值，就可以(yi)使充(chong)電(dian)(dian)器輸出電(dian)(dian)壓(ya)上升(sheng)或下降。

　　可以調節它(ta)，使(shi)輸出電壓為(wei)14Vx5左右，即可應急(ji)使(shi)用。不過需要注意，充電器(qi)次(ci)級濾(lv)(lv)波電容的耐壓值(48V充電器(qi)次(ci)級濾(lv)(lv)波電容的耐壓值多為(wei)63V)是否能承(cheng)受了。最好(hao)更換為(wei)耐壓100V的。

　　另外(wai)還得注意場效應管的散(san)熱問題和最(zui)大功(gong)耗問題(48V充電器多(duo)(duo)用8N60及以下的，60V充電器多(duo)(duo)用12N60及以上的)。
