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(che)和其他交(jiao)通工具(ju)相比(bi)，電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)車(che)不會(hui)(hui)排出有毒(du)的氣(qi)體、造成空(kong)氣(qi)污染(ran),這是(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)車(che)的最大(da)優點(dian)。但是(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)車(che)在使用過程中(zhong)沒(mei)電(dian)(dian)(dian)(dian)(dian)也是(shi)(shi)(shi)很頭疼(teng)的，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)過程漫長(chang)，而且(qie)如果選到質量(liang)(liang)差的電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)車(che)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器又(you)常(chang)常(chang)會(hui)(hui)出現問題。那(nei)什(shen)么牌子的電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)車(che)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器好呢(ni)？在小編看來，質量(liang)(liang)好、科技含量(liang)(liang)高、功能(neng)強(qiang)大(da)的電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)車(che)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器價格是(shi)(shi)(shi)不會(hui)(hui)太低(di)的，那(nei)種(zhong)低(di)價劣質的產品(pin)最好敬而遠之，真的，選擇一(yi)個優質的電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)車(che)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器的確能(neng)省下不少麻煩。
