一、充電時電源指示燈亮，充電指示燈橙色

首先請(qing)檢(jian)(jian)查一(yi)下(xia)充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)輸(shu)(shu)出插頭與(yu)電(dian)(dian)(dian)池(chi)盒(he)的(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)插頭有(you)(you)沒(mei)有(you)(you)插緊。如確定沒(mei)有(you)(you)問題，可檢(jian)(jian)查一(yi)下(xia)電(dian)(dian)(dian)池(chi)盒(he)上(shang)面的(de)(de)保險(xian)絲管是(shi)否開(kai)路或保險(xian)絲座有(you)(you)松(song)動接觸不(bu)(bu)良(liang)現象。另外，有(you)(you)的(de)(de)車(che)型(xing)要把電(dian)(dian)(dian)池(chi)鎖打開(kai)后才(cai)能充(chong)(chong)(chong)電(dian)(dian)(dian)。如果(guo)以上(shang)故障均排除(chu)，考慮一(yi)下(xia)充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)輸(shu)(shu)出線是(shi)否開(kai)路，可用萬用表電(dian)(dian)(dian)壓(ya)擋(dang)（200V擋(dang)）測量一(yi)下(xia)充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)的(de)(de)空載輸(shu)(shu)出電(dian)(dian)(dian)壓(ya)，應為41-44V（配(pei)36V電(dian)(dian)(dian)池(chi)因充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)不(bu)(bu)同有(you)(you)所(suo)不(bu)(bu)同），如沒(mei)有(you)(you)的(de)(de)話，可能是(shi)充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)輸(shu)(shu)出線開(kai)路，并將充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)打開(kai)，換一(yi)根輸(shu)(shu)出線，即可排除(chu)故障。注意：在更換充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)輸(shu)(shu)出線時(shi)，一(yi)定要注意原機的(de)(de)正負極不(bu)(bu)要接反。

二、電源指示燈不亮，充電指示燈也不亮

三、嚴重發熱，甚至有外殼燒化變形現象

這主(zhu)要是部(bu)分(fen)用戶(hu)經常(chang)(chang)隨(sui)車攜帶造成(cheng)部(bu)分(fen)元器(qi)件松動引起的(de)故障。主(zhu)要表現為：C18松動虛焊時，會造成(cheng)V1、V2工作狀態不正(zheng)常(chang)(chang)，熱量很大，嚴重(zhong)時充電器(qi)外殼(ke)變形，電路(lu)板(ban)燒焦，導致V1、V2損壞，可將C18重(zhong)新焊接好，檢查(cha)(cha)V1、V2、R4、R7。如仍不能排除故障，則需檢查(cha)(cha)D15、D21中是否有(you)一只開(kai)路(lu)，另外，有(you)些(xie)廠家(jia)的(de)輸(shu)出整(zheng)流(liu)管采用一只雙二(er)極(ji)管，其中一只開(kai)路(lu)亦造成(cheng)上述故障，有(you)時該故障會造成(cheng)V1、V2中一只損壞。需同時檢查(cha)(cha)及更(geng)換。

四、發熱量大且伴有異常響聲

故障(zhang)原因(yin)是輸出級(ji)消(xiao)振阻容(rong)R31、C17損壞所致。另(ling)外，C12開路或虛焊也會引起上述故障(zhang)。

五、工作時有異常響聲，充不進電

檢查電路(lu)板上C8是否(fou)有虛焊或損壞，一般更換C8均能解決。

六、工作時有異常響聲，電源指示燈與充電指示燈暗且閃爍

故障原(yuan)因(yin)是IC1損壞，更換(huan)時務必小心，不要將印制板銅箔損壞，更換(huan)正(zheng)常(chang)后(hou)，需調整R28使充電器輸出電壓在正(zheng)常(chang)工作范圍(wei)內。

七、輸出電壓很高

輸出(chu)電壓很高(gao)（大于50V），其故(gu)障原因是C15短路或(huo)R26開路，具(ju)體判斷時可測量IC1集成電路的“1”腳電壓。

注：更換R26后，應重新調整(zheng)R28使充電器輸(shu)出電壓保持正常。

八、輸出電壓正常，但充電電流很小

檢(jian)查R30、R11、R13是否接觸(chu)不良或損壞，如正常(chang)請(qing)更換IC1即可排除故障。

九、輸出電壓正常，充電指示燈無指示或指示不正確

通常(chang)是由于IC2損壞或LED2損壞，可更換。

十、輸出部分銅箔燒斷

打開充(chong)(chong)電器(qi)后發現充(chong)(chong)電器(qi)輸出部分銅箔燒斷(duan)，這通常是將(jiang)電池正負極反接的(de)結果，由此(ci)而引(yin)起(qi)的(de)故(gu)障將(jiang)會(hui)導致充(chong)(chong)電器(qi)許多元件損壞(huai)(huai)。如果充(chong)(chong)電器(qi)保險絲沒有(you)壞(huai)(huai)，則通常更(geng)換R30、IC1、IC2后將(jiang)斷(duan)銅箔連上即(ji)可恢(hui)復正常。如果充(chong)(chong)電器(qi)的(de)保險絲已斷(duan)，則故(gu)障較嚴重D1-D4、V1-V2、R4、R7等均(jun)有(you)可能(neng)損壞(huai)(huai)，需測量后逐一更(geng)換。

14、通(tong)電(dian)閃燈，請補焊(han)變(bian)壓(ya)器各(ge)引腳，然后試(shi)機，如果(guo)依舊(jiu)，請檢查431、光電(dian)耦合器、輸(shu)出部分各(ge)二極管(guan)是(shi)否(fou)(fou)短路，變(bian)壓(ya)器磁芯是(shi)否(fou)(fou)松(song)動，電(dian)源(yuan)輸(shu)入(ru)部分10歐小電(dian)阻是(shi)否(fou)(fou)開路。或代換3842再(zai)次試(shi)機。

16、輸(shu)出(chu)電壓低：補焊線路板(ban)。試機，然后將輸(shu)入(ru)輸(shu)出(chu)大電容換(huan)新再次試機。

17、輸(shu)出低(di)，發燙，如果(guo)輸(shu)出電壓低(di)于40多V，且功率管，變壓器(qi)發燙，一般(ban)為變壓器(qi)有問(wen)題(ti)。

19、燒3842,3842換新后試(shi)機插電聽(ting)到一聲喀的一聲響，這是(shi)測量大(da)電容2端電壓(ya)300V慢(man)慢(man)將，說(shuo)明(ming)3842又擊穿了，先補焊線(xian)路(lu)板(ban)，檢查變壓(ya)器引腳是(shi)否松動或者引線(xian)是(shi)否斷開(kai)，輸(shu)出(chu)部(bu)分大(da)二極管是(shi)否開(kai)路(lu)，線(xian)路(lu)板(ban)是(shi)否斷裂。

20、以上(shang)故障適合于市場上(shang)大部分單(dan)管(guan)電(dian)路充電(dian)器常見故障，操作過程中可隨時咨詢(xun)技術人員。

如48V充(chong)電(dian)(dian)(dian)器(qi)，最(zui)高電(dian)(dian)(dian)壓(ya)(ya)不(bu)(bu)大(da)于(yu)59.6V，大(da)于(yu)此電(dian)(dian)(dian)壓(ya)(ya)，充(chong)電(dian)(dian)(dian)可(ke)能(neng)不(bu)(bu)轉燈，低電(dian)(dian)(dian)壓(ya)(ya)不(bu)(bu)低于(yu)55V，低于(yu)此電(dian)(dian)(dian)壓(ya)(ya)造成(cheng)充(chong)電(dian)(dian)(dian)不(bu)(bu)足，長時(shi)間容易對電(dian)(dian)(dian)池虧電(dian)(dian)(dian)。 電(dian)(dian)(dian)流(liu)，如48V20A充(chong)電(dian)(dian)(dian)器(qi)，最(zui)大(da)電(dian)(dian)(dian)流(liu)不(bu)(bu)大(da)于(yu)3A。大(da)于(yu)3A可(ke)能(neng)造成(cheng)電(dian)(dian)(dian)池失水較早，最(zui)低不(bu)(bu)低于(yu)2.1A。低壓(ya)(ya)此電(dian)(dian)(dian)流(liu)造成(cheng)充(chong)電(dian)(dian)(dian)不(bu)(bu)足。

1、48V新電(dian)(dian)(dian)池要求充(chong)(chong)電(dian)(dian)(dian)器參數，最高(gao)電(dian)(dian)(dian)壓58.5---59.7，不(bu)(bu)低(di)于58V，低(di)于58V造(zao)(zao)成(cheng)(cheng)充(chong)(chong)電(dian)(dian)(dian)不(bu)(bu)足，高(gao)于59.7V可能(neng)造(zao)(zao)成(cheng)(cheng)充(chong)(chong)電(dian)(dian)(dian)不(bu)(bu)轉燈(deng)。轉燈(deng)電(dian)(dian)(dian)流約(yue)0.4---0.7A，實(shi)際電(dian)(dian)(dian)壓約(yue)55.5V，低(di)于50V造(zao)(zao)成(cheng)(cheng)充(chong)(chong)電(dian)(dian)(dian)不(bu)(bu)足，長(chang)時間(jian)充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池虧電(dian)(dian)(dian)。

2、4820電池要求(qiu)充電最大(da)電流2.4----3.3A，低于(yu)2.2A充電慢(man)，充電效果差(cha)。

3、市場(chang)上低于(yu)30元的充電器(qi)實際功率小，參數設計不精確，請(qing)注(zhu)意(yi)區分(fen)。

4、充電(dian)器穩壓(ya)電(dian)路失效會造(zao)成輸出(chu)電(dian)壓(ya)75---130V，充電(dian)電(dian)池滾燙不轉燈(deng)。

5、當新(xin)電池(chi)出現，續(xu)航里程20A電池(chi)低(di)于30公(gong)里，12A電池(chi)低(di)于25公(gong)里請檢查(cha)充電器各(ge)項參數，如果無法(fa)判(pan)斷是，請更換優(you)質充電器再次使用(yong)，即可解決問題(ti)。

6、新電池遇到不(bu)轉(zhuan)燈時(shi)，請(qing)更換另(ling)外一個優質充電器試機。

7、正(zheng)常情況下。4820新電(dian)池(chi)充電(dian)時間(jian)約10小(xiao)時左右(you)，續(xu)航里(li)程40---60公里(li)，4812新電(dian)池(chi)充電(dian)時間(jian)約10小(xiao)時內，里(li)程達到25---40公里(li)，如果正(zheng)常充電(dian)時間(jian)超過以上(shang)，請(qing)更換優質充電(dian)器再次使(shi)用(yong)。

8、有很多充電(dian)器內(nei)部(bu)電(dian)路(lu)、輸(shu)入輸(shu)出連線老化，造(zao)成，有時(shi)候(hou)能充、有時(shi)候(hou)不(bu)能沖。嚴重(zhong)影響電(dian)池，或者充電(dian)過程中(zhong)電(dian)路(lu)失(shi)效(xiao)，造(zao)成充鼓(gu)包，如果出現這種情況，請直接更換優質充電(dian)器再次使用(yong)。
