電動車以其出行便捷、低碳環保的優(you)勢已進入我們的生活(huo)，但它的故障(zhang)率(lv)較(jiao)高本人根據飛天鷹科技多(duo)年的研發生產經驗，總結了電(dian)動自(zi)行車電(dian)源(yuan)適配器故障(zhang)維(wei)修方法，供大家參(can)考。

1、電(dian)(dian)(dian)(dian)源(yuan)不(bu)啟(qi)動(dong)：插(cha)電(dian)(dian)(dian)(dian)源(yuan)，大電(dian)(dian)(dian)(dian)容有300V電(dian)(dian)(dian)(dian)壓、拔掉(diao)(diao)電(dian)(dian)(dian)(dian)源(yuan)再次測量大電(dian)(dian)(dian)(dian)容2端還是(shi)300V電(dian)(dian)(dian)(dian)壓不(bu)下降(jiang)。給(gei)電(dian)(dian)(dian)(dian)容放電(dian)(dian)(dian)(dian)后，將啟(qi)動(dong)電(dian)(dian)(dian)(dian)阻換掉(diao)(diao)即可。啟(qi)動(dong)電(dian)(dian)(dian)(dian)阻在電(dian)(dian)(dian)(dian)源(yuan)輸入部分，阻值150K，功率2W。

2、啟動困難：有時(shi)候能起到有時(shi)候不能啟動，補焊線(xian)路板，后試機，如果依舊請將(jiang)輸入部(bu)分小電容換新再次試機，50V47UF。

3、電(dian)(dian)(dian)動車充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)一(yi)直綠燈：有四種(zhong)情況(kuang)。充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)的轉換器(qi)(qi)損壞(huai)，不能轉換和(he)充(chong)(chong)(chong)電(dian)(dian)(dian)，更(geng)換充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)電(dian)(dian)(dian)阻；電(dian)(dian)(dian)池開焊，用(yong)萬用(yong)表檢查；充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)保險燒壞(huai)，更(geng)換充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)；電(dian)(dian)(dian)源線(xian)與電(dian)(dian)(dian)池插口(kou)處脫落、接觸不良，檢查更(geng)換。

4、輸(shu)出電(dian)壓高：通電(dian)，電(dian)壓高于70多V，充電(dian)不轉燈，先將(jiang)電(dian)路(lu)板補焊一遍，再次試(shi)(shi)機，如(ru)果還是電(dian)壓高，請更換(huan)光電(dian)耦合(he)器、再次試(shi)(shi)機、還是輸(shu)出高，更換(huan)431基準(zhun)穩(wen)壓器，再次試(shi)(shi)機。

5、發熱量大(da)且(qie)伴有異常響聲：故障(zhang)原因是輸出(chu)級消振阻容(rong)R31、C17損壞所致。另外(wai)，C12開路或虛焊也會引起上述故障(zhang)。

6、輸出(chu)電(dian)壓不穩定：先將電(dian)路(lu)板(ban)補焊一遍，后(hou)試(shi)機，然后(hou)將輸出(chu)端電(dian)容63V470UF電(dian)容換新(xin)試(shi)機即可(ke)。

7.輸出低(di)，發燙：如果輸出電壓(ya)(ya)低(di)于40多V，且功率管(guan)，變壓(ya)(ya)器發燙，一般為變壓(ya)(ya)器有問(wen)題。

當你的(de)電動(dong)車電源適配器出現(xian)充電問題時，可(ke)以(yi)(yi)按照(zhao)上(shang)面(mian)的(de)問題對號入座，快速的(de)找到問題，然后就可(ke)以(yi)(yi)迅(xun)速的(de)解決。
