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(nei)這(zhe)(zhe)些(xie)電動車(che)充電器能否混(hun)用?如果有電動車(che)標稱電壓為48V的電池(chi)組所配(pei)的充電器，這(zhe)(zhe)能否對標稱電壓為60V的電池(chi)組充電?這(zhe)(zhe)是要分情(qing)況討(tao)論的：

　　1、如果標稱電(dian)(dian)(dian)壓為(wei)60V的(de)(de)鉛酸蓄電(dian)(dian)(dian)池(chi)組完全放電(dian)(dian)(dian)、且(qie)手頭一(yi)時找不到配套的(de)(de)充(chong)電(dian)(dian)(dian)器，只有48V的(de)(de)鉛酸蓄電(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)器，在輸出插頭和60V電(dian)(dian)(dian)池(chi)組充(chong)電(dian)(dian)(dian)孔插座(zuo)極性一(yi)致的(de)(de)條(tiao)件下，是可以用來對(dui)60V電(dian)(dian)(dian)池(chi)組充(chong)電(dian)(dian)(dian)的(de)(de)。

　　因為(wei)60V電池組放電完畢(bi)后，電壓為(wei)10.5x5=52.5V，而48V充電器的最高輸出電壓為(wei)14.4x4V，要比52.5V高。因此可以(yi)少量(liang)補充一些電的。待(dai)電池組電壓上升到14.4x4V時，充電結束。

　　有(you)人說了，這(zhe)(zhe)還沒有(you)充滿嘛(ma)!有(you)什么用?這(zhe)(zhe)就(jiu)說錯了：對于(yu)鉛酸(suan)蓄(xu)(xu)電(dian)池而言，放(fang)光電(dian)之后(hou)如果不及時(shi)充電(dian)，正(zheng)、負(fu)極板上(shang)的硫酸(suan)鉛就(jiu)開始(shi)結晶——這(zhe)(zhe)就(jiu)是鉛酸(suan)蓄(xu)(xu)電(dian)池的癌癥(zheng)病灶!稱為(wei)硫化。隨著硫化的不斷發展，鉛酸(suan)蓄(xu)(xu)電(dian)池的容量(liang)不斷下降(jiang)，最(zui)終死亡——報廢了。能在第(di)一時(shi)間阻擊癌癥(zheng)，為(wei)什么不干?

　　2、如果60V電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)組(zu)的(de)兩端電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，要(yao)大于等于48V充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器最高輸出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，用(yong)48V充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器，是(shi)不能(neng)對60V電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)組(zu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)。因為(wei)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)是(shi)需(xu)要(yao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)位(wei)差(cha)的(de)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)高的(de)向(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)低的(de)才能(neng)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)。不過(guo)你也不用(yong)擔心，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)高于充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)時，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)會倒灌(guan)——充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)中，都(dou)設(she)有防反接(jie)和倒充(chong)(chong)(chong)(chong)的(de)二(er)極管。

　　3、如果你有動手能力的(de)話，可(ke)以拆開48V充(chong)電(dian)器，找到調(diao)整輸(shu)出(chu)電(dian)壓的(de)元件(如384x類(lei)充(chong)電(dian)器接光(guang)耦的(de)那個431)，調(diao)節431上的(de)分壓電(dian)阻阻值(zhi)，就可(ke)以使(shi)充(chong)電(dian)器輸(shu)出(chu)電(dian)壓上升或下降。

　　可以(yi)調節(jie)它(ta)，使(shi)輸出電壓(ya)為14Vx5左右，即可應急使(shi)用。不過(guo)需要注(zhu)意，充電器次(ci)級濾波(bo)電容的(de)耐(nai)壓(ya)值(48V充電器次(ci)級濾波(bo)電容的(de)耐(nai)壓(ya)值多為63V)是(shi)否能承受了。最好更換為耐(nai)壓(ya)100V的(de)。

　　另(ling)外還得注(zhu)意場效應管的(de)散(san)熱問題和(he)最大功(gong)耗問題(48V充電器(qi)多用8N60及以下的(de)，60V充電器(qi)多用12N60及以上的(de))。
