電動車充電器是專門為電動自行車的電瓶配置的一個充電設備！充電器的分類： 用有、無工頻（50赫茲）變壓器區分，可分為兩大類。貨運三輪充電器一般使用帶工頻變壓器的充電機，體積大、重量大、費電，但是可靠，便宜；電動自行車和電摩則使用所謂開關電源式充電器，省電，效率高，但是易壞。
開關電源式充電器的正確操作是：充電時，先插電池，后加市電；充足后，先切斷市電，后拔電池插頭。如果在充電時先拔電池插頭，特別是充電電流大（紅燈）時，非常容易損壞充電器。常用的開關電源式充電器又分半橋式和單激式兩大類，單激類又分為正激式和反激式兩類。半橋式成本高，性能好，常用于帶負脈沖的充電器；單激式成本低，市場占有率高。

與汽車和其他(ta)交(jiao)通(tong)工具相比，電(dian)(dian)(dian)(dian)(dian)動車不會(hui)(hui)排出有毒(du)的(de)(de)(de)(de)(de)氣體(ti)、造成空氣污染,這是(shi)電(dian)(dian)(dian)(dian)(dian)動車的(de)(de)(de)(de)(de)最大(da)優點。但是(shi)電(dian)(dian)(dian)(dian)(dian)動車在(zai)使用過程(cheng)(cheng)中沒電(dian)(dian)(dian)(dian)(dian)也是(shi)很頭疼的(de)(de)(de)(de)(de)，充(chong)電(dian)(dian)(dian)(dian)(dian)過程(cheng)(cheng)漫(man)長，而且如果選到(dao)質(zhi)(zhi)量差的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)動車充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)又常常會(hui)(hui)出現問題(ti)。那什么牌子的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)動車充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)好(hao)呢(ni)？在(zai)小編看來，質(zhi)(zhi)量好(hao)、科技含量高、功能強大(da)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)動車充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)價(jia)格是(shi)不會(hui)(hui)太低的(de)(de)(de)(de)(de)，那種低價(jia)劣質(zhi)(zhi)的(de)(de)(de)(de)(de)產品最好(hao)敬而遠(yuan)之，真的(de)(de)(de)(de)(de)，選擇(ze)一個優質(zhi)(zhi)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)動車充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)的(de)(de)(de)(de)(de)確能省下不少麻煩。
