很多人都(dou)反映才剛買不久就出現了一些問題？這(zhe)些問題是真(zhen)的“有問題”嗎？下面充電(dian)器廠家給(gei)大家介紹幾種常識，了解(jie)(jie)之后“問題”就迎刃(ren)而解(jie)(jie)。

 一(yi)、充電(dian)時電(dian)源指(zhi)示燈(deng)亮，充電(dian)指(zhi)示燈(deng)橙色

 首先請(qing)檢(jian)查一(yi)下(xia)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)輸(shu)(shu)(shu)出(chu)插(cha)頭(tou)(tou)與(yu)電(dian)(dian)(dian)(dian)(dian)池(chi)盒的(de)(de)(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)插(cha)頭(tou)(tou)有(you)(you)沒(mei)有(you)(you)插(cha)緊。如確定沒(mei)有(you)(you)問(wen)題，可檢(jian)查一(yi)下(xia)電(dian)(dian)(dian)(dian)(dian)池(chi)盒上面的(de)(de)(de)(de)保險(xian)絲管是否(fou)開路(lu)或保險(xian)絲座有(you)(you)松動(dong)接觸不良(liang)現象(xiang)。另外，有(you)(you)的(de)(de)(de)(de)車型要把電(dian)(dian)(dian)(dian)(dian)池(chi)鎖(suo)打開后(hou)才能充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)。如果(guo)以上故障均排除(chu)(chu)，考慮一(yi)下(xia)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)輸(shu)(shu)(shu)出(chu)線是否(fou)開路(lu)，可用(yong)萬用(yong)表電(dian)(dian)(dian)(dian)(dian)壓(ya)擋（200V擋）測(ce)量一(yi)下(xia)電(dian)(dian)(dian)(dian)(dian)源器(qi)(qi)的(de)(de)(de)(de)空載(zai)輸(shu)(shu)(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)壓(ya)，應為41-44V（配36V電(dian)(dian)(dian)(dian)(dian)池(chi)因充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)不同(tong)有(you)(you)所不同(tong)），如沒(mei)有(you)(you)的(de)(de)(de)(de)話，可能是充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)輸(shu)(shu)(shu)出(chu)線開路(lu)，并將(jiang)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)打開，換(huan)一(yi)根輸(shu)(shu)(shu)出(chu)線，即(ji)可排除(chu)(chu)故障。注意：在更換(huan)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)輸(shu)(shu)(shu)出(chu)線時，一(yi)定要注意原機的(de)(de)(de)(de)正負極不要接反。

 二、電源指(zhi)示(shi)(shi)燈不亮(liang)，充(chong)電指(zhi)示(shi)(shi)燈也不亮(liang)

 檢(jian)查(cha)電(dian)(dian)源(yuan)適配器(qi)輸(shu)(shu)入電(dian)(dian)源(yuan)插(cha)頭(tou)與市電(dian)(dian)有(you)(you)(you)沒有(you)(you)(you)連接(jie)好(hao)，可(ke)將充電(dian)(dian)器(qi)輸(shu)(shu)入插(cha)頭(tou)插(cha)至正常的(de)(de)電(dian)(dian)源(yuan)插(cha)座(zuo)(zuo)中試(shi)一(yi)(yi)下，如情況依(yi)舊，將充電(dian)(dian)器(qi)外殼打開，觀(guan)察一(yi)(yi)下機(ji)(ji)內保險(xian)(xian)(xian)絲(si)(si)有(you)(you)(you)沒有(you)(you)(you)斷，如沒有(you)(you)(you)斷，先(xian)檢(jian)查(cha)一(yi)(yi)下電(dian)(dian)源(yuan)輸(shu)(shu)入線是否(fou)(fou)良(liang)好(hao)，在排除電(dian)(dian)源(yuan)輸(shu)(shu)入線的(de)(de)故障(zhang)后，應檢(jian)查(cha)一(yi)(yi)下電(dian)(dian)路(lu)板上高壓(ya)區附近的(de)(de)元(yuan)器(qi)件是否(fou)(fou)有(you)(you)(you)虛(xu)焊，保險(xian)(xian)(xian)絲(si)(si)座(zuo)(zuo)是否(fou)(fou)有(you)(you)(you)接(jie)觸不良(liang)現象，重點檢(jian)查(cha)變壓(ya)器(qi)T1、三極管(guan)V1、V2等是否(fou)(fou)有(you)(you)(you)虛(xu)焊現象。另外，R5或R6開路(lu)，也會(hui)(hui)引起上述故障(zhang)，如機(ji)(ji)內保險(xian)(xian)(xian)絲(si)(si)已(yi)斷，則千萬(wan)不要更換(huan)大安培的(de)(de)保險(xian)(xian)(xian)絲(si)(si)管(guan)（充電(dian)(dian)器(qi)的(de)(de)保險(xian)(xian)(xian)絲(si)(si)管(guan)一(yi)(yi)般為2A），應重點檢(jian)查(cha)D1-D4、V1、V2、R4、R7及(ji)D15、D21 有(you)(you)(you)無損(sun)壞(huai)(huai)，如有(you)(you)(you)損(sun)壞(huai)(huai)，可(ke)用同(tong)類型的(de)(de)更換(huan)。請注意，上述元(yuan)件損(sun)壞(huai)(huai)時(shi)，可(ke)能(neng)會(hui)(hui)同(tong)時(shi)損(sun)壞(huai)(huai)一(yi)(yi)到(dao)二個，有(you)(you)(you)時(shi)可(ke)能(neng)會(hui)(hui)同(tong)時(shi)損(sun)壞(huai)(huai)好(hao)幾個，檢(jian)修時(shi)需要逐一(yi)(yi)檢(jian)查(cha)、更換(huan)這(zhe)些元(yuan)件后才能(neng)通電(dian)(dian)。

 三、嚴重發熱，甚至有(you)外殼燒化(hua)變(bian)形(xing)現象

 這主要是部分用戶經常隨車攜帶(dai)造(zao)成(cheng)部分元器(qi)件松動(dong)引起的(de)故(gu)(gu)障。主要表(biao)現為(wei)：C18松動(dong)虛焊時(shi)，會造(zao)成(cheng)V1、V2工作狀態不(bu)正(zheng)常，熱(re)量很(hen)大，嚴重時(shi)充電器(qi)外殼變形，電路(lu)(lu)板燒焦，導致(zhi)V1、V2損壞，可(ke)將C18重新焊接好，檢查(cha)V1、V2、R4、R7。如仍不(bu)能排(pai)除故(gu)(gu)障，則需檢查(cha)D15、D21中(zhong)(zhong)是否有(you)(you)一(yi)只(zhi)開(kai)路(lu)(lu)，另外，有(you)(you)些廠家(jia)的(de)輸出整流管(guan)采用一(yi)只(zhi)雙二(er)極管(guan)，其中(zhong)(zhong)一(yi)只(zhi)開(kai)路(lu)(lu)亦(yi)造(zao)成(cheng)上述故(gu)(gu)障，有(you)(you)時(shi)該故(gu)(gu)障會造(zao)成(cheng) V1、V2中(zhong)(zhong)一(yi)只(zhi)損壞。需同時(shi)檢查(cha)及更(geng)換。

 四、發熱量大且伴(ban)有異常(chang)響(xiang)聲

 故障原因是輸出級消振阻容R31、C17損壞所致。另外，C12開路或虛(xu)焊也會引起上述(shu)故障。

 五、工作時有異(yi)常響聲，充不進(jin)電

 檢查電路板上C8是否(fou)有虛焊或(huo)損(sun)壞，一般更(geng)換C8均能解決。

 六、工作時有異常響聲，電源(yuan)指(zhi)示燈與充電指(zhi)示燈暗(an)且閃(shan)爍

 故障原(yuan)因是IC1損壞，更換時務必小心(xin)，不要(yao)將印制板銅箔損壞，更換正(zheng)常后，需調整R28使電源適配器輸出(chu)電壓在正(zheng)常工作(zuo)范圍內。
