很多人都反(fan)映才剛買不久就(jiu)(jiu)出現(xian)了一(yi)些問題？這(zhe)些問題是真的“有問題”嗎？下(xia)面(mian)充電器廠(chang)家(jia)給大家(jia)介(jie)紹幾種常識，了解之后“問題”就(jiu)(jiu)迎刃(ren)而解。

 一(yi)、充電時電源(yuan)指(zhi)示燈(deng)亮，充電指(zhi)示燈(deng)橙色

 首先請檢查一(yi)下(xia)充(chong)電(dian)器(qi)(qi)輸(shu)(shu)(shu)出(chu)插(cha)頭與(yu)電(dian)池盒的充(chong)電(dian)插(cha)頭有沒有插(cha)緊。如確定(ding)沒有問題，可檢查一(yi)下(xia)電(dian)池盒上面的保(bao)險絲(si)管是(shi)否開(kai)路(lu)或保(bao)險絲(si)座有松動接觸不良現象。另外，有的車型要把電(dian)池鎖打開(kai)后才能充(chong)電(dian)。如果以上故(gu)障(zhang)均排除，考慮一(yi)下(xia)充(chong)電(dian)器(qi)(qi)輸(shu)(shu)(shu)出(chu)線(xian)是(shi)否開(kai)路(lu)，可用(yong)萬用(yong)表電(dian)壓擋(dang)（200V擋(dang)）測量一(yi)下(xia)電(dian)源(yuan)器(qi)(qi)的空載輸(shu)(shu)(shu)出(chu)電(dian)壓，應為41-44V（配36V電(dian)池因充(chong)電(dian)器(qi)(qi)不同(tong)有所不同(tong)），如沒有的話，可能是(shi)充(chong)電(dian)器(qi)(qi)輸(shu)(shu)(shu)出(chu)線(xian)開(kai)路(lu)，并將充(chong)電(dian)器(qi)(qi)打開(kai)，換(huan)一(yi)根輸(shu)(shu)(shu)出(chu)線(xian)，即(ji)可排除故(gu)障(zhang)。注(zhu)意(yi)：在(zai)更(geng)換(huan)充(chong)電(dian)器(qi)(qi)輸(shu)(shu)(shu)出(chu)線(xian)時，一(yi)定(ding)要注(zhu)意(yi)原機的正負極不要接反。

 二、電源指示燈不亮，充電指示燈也不亮

 檢查(cha)電(dian)(dian)(dian)源(yuan)適配器(qi)(qi)輸(shu)(shu)入電(dian)(dian)(dian)源(yuan)插頭與市電(dian)(dian)(dian)有(you)(you)沒(mei)(mei)有(you)(you)連接好(hao)，可(ke)將充(chong)電(dian)(dian)(dian)器(qi)(qi)輸(shu)(shu)入插頭插至正常的電(dian)(dian)(dian)源(yuan)插座(zuo)中試一(yi)下(xia)，如(ru)情況(kuang)依舊，將充(chong)電(dian)(dian)(dian)器(qi)(qi)外殼打(da)開，觀察一(yi)下(xia)機內保(bao)(bao)險絲(si)有(you)(you)沒(mei)(mei)有(you)(you)斷，如(ru)沒(mei)(mei)有(you)(you)斷，先檢查(cha)一(yi)下(xia)電(dian)(dian)(dian)源(yuan)輸(shu)(shu)入線是(shi)否(fou)良(liang)好(hao)，在(zai)排(pai)除電(dian)(dian)(dian)源(yuan)輸(shu)(shu)入線的故(gu)障后，應檢查(cha)一(yi)下(xia)電(dian)(dian)(dian)路板上高(gao)壓(ya)區附近的元器(qi)(qi)件(jian)是(shi)否(fou)有(you)(you)虛(xu)焊，保(bao)(bao)險絲(si)座(zuo)是(shi)否(fou)有(you)(you)接觸不良(liang)現象(xiang)，重點檢查(cha)變(bian)壓(ya)器(qi)(qi)T1、三(san)極管(guan)(guan)V1、V2等是(shi)否(fou)有(you)(you)虛(xu)焊現象(xiang)。另外，R5或R6開路，也會引起上述故(gu)障，如(ru)機內保(bao)(bao)險絲(si)已斷，則(ze)千萬不要(yao)更換(huan)大(da)安培的保(bao)(bao)險絲(si)管(guan)(guan)（充(chong)電(dian)(dian)(dian)器(qi)(qi)的保(bao)(bao)險絲(si)管(guan)(guan)一(yi)般為2A），應重點檢查(cha)D1-D4、V1、V2、R4、R7及D15、D21 有(you)(you)無(wu)損壞，如(ru)有(you)(you)損壞，可(ke)用同(tong)類型(xing)的更換(huan)。請注(zhu)意，上述元件(jian)損壞時(shi)(shi)(shi)，可(ke)能(neng)(neng)會同(tong)時(shi)(shi)(shi)損壞一(yi)到(dao)二個，有(you)(you)時(shi)(shi)(shi)可(ke)能(neng)(neng)會同(tong)時(shi)(shi)(shi)損壞好(hao)幾(ji)個，檢修時(shi)(shi)(shi)需(xu)要(yao)逐一(yi)檢查(cha)、更換(huan)這(zhe)些元件(jian)后才(cai)能(neng)(neng)通電(dian)(dian)(dian)。

 三、嚴重發(fa)熱，甚至有外(wai)殼燒(shao)化變(bian)形現(xian)象(xiang)

 這主要是部(bu)分用戶經常隨車攜帶造(zao)(zao)成(cheng)(cheng)部(bu)分元器件松(song)動引起的故障。主要表現(xian)為：C18松(song)動虛焊時，會(hui)造(zao)(zao)成(cheng)(cheng)V1、V2工(gong)作(zuo)狀態不正常，熱量很大，嚴重時充電(dian)器外殼變形，電(dian)路板燒焦，導致V1、V2損(sun)壞，可將(jiang)C18重新(xin)焊接好，檢查V1、V2、R4、R7。如仍(reng)不能排除故障，則(ze)需(xu)檢查D15、D21中是否有一(yi)(yi)只(zhi)開路，另外，有些廠家的輸出(chu)整流管采用一(yi)(yi)只(zhi)雙二極管，其中一(yi)(yi)只(zhi)開路亦造(zao)(zao)成(cheng)(cheng)上述故障，有時該故障會(hui)造(zao)(zao)成(cheng)(cheng) V1、V2中一(yi)(yi)只(zhi)損(sun)壞。需(xu)同時檢查及更(geng)換。

 四、發熱量大且伴有異常響聲

 故障原因是輸出級消(xiao)振阻容R31、C17損壞所致。另外，C12開(kai)路或(huo)虛焊也會引起上述(shu)故障。

 五、工作(zuo)時(shi)有(you)異常響聲，充不進電(dian)

 檢查電路板(ban)上(shang)C8是否有虛焊(han)或損壞，一般更換(huan)C8均能解(jie)決(jue)。

 六、工作時有(you)異常(chang)響聲，電源指(zhi)示(shi)燈與充電指(zhi)示(shi)燈暗且(qie)閃爍

 故障原因是IC1損壞，更(geng)換(huan)時務(wu)必(bi)小(xiao)心，不(bu)要將印制板銅箔損壞，更(geng)換(huan)正常后，需調整(zheng)R28使電(dian)源適配器輸出(chu)電(dian)壓在正常工作范圍(wei)內。
