如何才能選擇到好的充電器呢？
1.充電器殼子要堅實，電源線要比較粗，插頭部分要厚實。
2.相關的質量認證，比如3C、質量監督局的檢測合格號等
3.看充電器廠家名稱、聯系方式、出廠日期等，確定不是三無產品。
如果(guo)以(yi)上條(tiao)件(jian)都符合，那(nei)么這個充電(dian)器基本(ben)上可(ke)以(yi)放(fang)心購買。

其次，要選擇一個與自己愛車電池參數相符合的充電器。
1.要選擇合適的電氣參數，看是36V還是48V ，是12AH還是20AH。
2.要清楚自己車子使用的電池類型，現在市面上的電動車90%以上配套的都是鉛酸蓄電池，與其它類型的電池（如鋰電池）相比，雖然電氣參數可能相同，但不同的電池使用的是不同的充電器，不能混用。
3.要清楚電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)車(che)(che)(che)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器輸(shu)出(chu)(chu)的屬性。看(kan)看(kan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)車(che)(che)(che)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)接(jie)口(kou)是(shi)圓形(xing)還(huan)是(shi)品字形(xing)，因輸(shu)出(chu)(chu)插頭(tou)出(chu)(chu)來(lai)的是(shi)有正(zheng)負(fu)(fu)極(ji)(ji)之分的直(zhi)流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，由于廠家不(bu)(bu)同，有的品字形(xing)插頭(tou)正(zheng)負(fu)(fu)極(ji)(ji)不(bu)(bu)一(yi)樣。不(bu)(bu)過沒(mei)關系，有一(yi)個很簡單的方法，就是(shi)拿一(yi)只萬(wan)用(yong)表量一(yi)下電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)車(che)(che)(che)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)接(jie)口(kou)，找出(chu)(chu)哪個是(shi)正(zheng)極(ji)(ji)哪個是(shi)負(fu)(fu)極(ji)(ji)，只要電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)車(che)(che)(che)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器輸(shu)出(chu)(chu)的跟電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)車(che)(che)(che)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)插口(kou)一(yi)致就可以了，即輸(shu)出(chu)(chu)的正(zheng)極(ji)(ji)對(dui)應電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)車(che)(che)(che)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)接(jie)口(kou)的正(zheng)極(ji)(ji)，輸(shu)出(chu)(chu)的負(fu)(fu)極(ji)(ji)對(dui)應電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)車(che)(che)(che)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)接(jie)口(kou)的負(fu)(fu)極(ji)(ji)，千萬(wan)不(bu)(bu)能搞反(fan)正(zheng)負(fu)(fu)極(ji)(ji)，不(bu)(bu)然會損(sun)壞充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)。

那么，在選擇了一個對應的充電器之后，又該如何對它維護保養呢？
1.使用充電器對蓄電池充電時，請先插上充電器的輸出插頭，后插輸入插頭。充電時，充電器的電源指示燈顯示紅色，充電指示燈也顯示為紅色。充滿后，充電指示燈為綠色。停止充電時，請先拔下充電器的輸入插頭，后拔充電器的輸出插頭。
2.充電器在使用過程中需防潮防濕，因此要放置在通風良好的地方。充電器工作時有一定的溫升，請注意散熱，通常充電時間在7-8小時內，視電池的使用狀態而不同。
3.充電器(qi)屬于較精密的電子(zi)設備，因(yin)此在使用中(zhong)要注意防震動。盡量(liang)不要隨身攜(xie)帶(dai)，如確(que)要攜(xie)帶(dai)，應將充電器(qi)用減(jian)震材料包裝(zhuang)好后(hou)放置在車上工具箱內。
