一、充電時電源指示燈亮，充電指示燈橙色

首先請檢查一(yi)下(xia)(xia)充(chong)(chong)電(dian)(dian)(dian)(dian)器輸(shu)出(chu)(chu)插(cha)頭(tou)與電(dian)(dian)(dian)(dian)池(chi)盒的(de)充(chong)(chong)電(dian)(dian)(dian)(dian)插(cha)頭(tou)有沒(mei)有插(cha)緊(jin)。如確定沒(mei)有問(wen)題(ti)，可檢查一(yi)下(xia)(xia)電(dian)(dian)(dian)(dian)池(chi)盒上(shang)面的(de)保險絲管是(shi)否(fou)開(kai)路(lu)或保險絲座有松動接觸不(bu)(bu)良(liang)現(xian)象。另(ling)外，有的(de)車型要把電(dian)(dian)(dian)(dian)池(chi)鎖打(da)開(kai)后才能(neng)充(chong)(chong)電(dian)(dian)(dian)(dian)。如果以上(shang)故障均排(pai)除，考慮一(yi)下(xia)(xia)充(chong)(chong)電(dian)(dian)(dian)(dian)器輸(shu)出(chu)(chu)線(xian)是(shi)否(fou)開(kai)路(lu)，可用(yong)萬用(yong)表電(dian)(dian)(dian)(dian)壓擋（200V擋）測(ce)量一(yi)下(xia)(xia)充(chong)(chong)電(dian)(dian)(dian)(dian)器的(de)空載(zai)輸(shu)出(chu)(chu)電(dian)(dian)(dian)(dian)壓，應為41-44V（配36V電(dian)(dian)(dian)(dian)池(chi)因充(chong)(chong)電(dian)(dian)(dian)(dian)器不(bu)(bu)同有所不(bu)(bu)同），如沒(mei)有的(de)話，可能(neng)是(shi)充(chong)(chong)電(dian)(dian)(dian)(dian)器輸(shu)出(chu)(chu)線(xian)開(kai)路(lu)，并將充(chong)(chong)電(dian)(dian)(dian)(dian)器打(da)開(kai)，換一(yi)根輸(shu)出(chu)(chu)線(xian)，即可排(pai)除故障。注意：在更換充(chong)(chong)電(dian)(dian)(dian)(dian)器輸(shu)出(chu)(chu)線(xian)時，一(yi)定要注意原機(ji)的(de)正(zheng)負(fu)極不(bu)(bu)要接反。

二、電源指示燈不亮，充電指示燈也不亮

檢(jian)查(cha)充電(dian)器(qi)輸入(ru)電(dian)源(yuan)(yuan)插(cha)頭與市電(dian)有(you)(you)(you)(you)沒(mei)有(you)(you)(you)(you)連接好(hao)，可(ke)將(jiang)(jiang)充電(dian)器(qi)輸入(ru)插(cha)頭插(cha)至正常的電(dian)源(yuan)(yuan)插(cha)座中試一(yi)(yi)(yi)下，如(ru)情(qing)況(kuang)依(yi)舊，將(jiang)(jiang)充電(dian)器(qi)外殼打開(kai)，觀察一(yi)(yi)(yi)下機內(nei)保險(xian)(xian)絲(si)有(you)(you)(you)(you)沒(mei)有(you)(you)(you)(you)斷，如(ru)沒(mei)有(you)(you)(you)(you)斷，先(xian)檢(jian)查(cha)一(yi)(yi)(yi)下電(dian)源(yuan)(yuan)輸入(ru)線(xian)是否(fou)(fou)良好(hao)，在排除電(dian)源(yuan)(yuan)輸入(ru)線(xian)的故障后(hou)，應(ying)(ying)檢(jian)查(cha)一(yi)(yi)(yi)下電(dian)路板上高(gao)壓區附近的元(yuan)器(qi)件(jian)(jian)是否(fou)(fou)有(you)(you)(you)(you)虛焊，保險(xian)(xian)絲(si)座是否(fou)(fou)有(you)(you)(you)(you)接觸不(bu)(bu)良現象，重點(dian)(dian)檢(jian)查(cha)變壓器(qi)T1、三(san)極管V1、V2等(deng)是否(fou)(fou)有(you)(you)(you)(you)虛焊現象。另外，R5或R6開(kai)路，也會引起上述故障，如(ru)機內(nei)保險(xian)(xian)絲(si)已斷，則千(qian)萬不(bu)(bu)要更換(huan)大安培的保險(xian)(xian)絲(si)管（充電(dian)器(qi)的保險(xian)(xian)絲(si)管一(yi)(yi)(yi)般為2A），應(ying)(ying)重點(dian)(dian)檢(jian)查(cha)D1-D4、V1、V2、R4、R7及D15、D21有(you)(you)(you)(you)無(wu)損(sun)壞(huai)，如(ru)有(you)(you)(you)(you)損(sun)壞(huai)，可(ke)用同類型的更換(huan)。請注意，上述元(yuan)件(jian)(jian)損(sun)壞(huai)時(shi)，可(ke)能(neng)會同時(shi)損(sun)壞(huai)一(yi)(yi)(yi)到二個，有(you)(you)(you)(you)時(shi)可(ke)能(neng)會同時(shi)損(sun)壞(huai)好(hao)幾個，檢(jian)修時(shi)需要逐一(yi)(yi)(yi)檢(jian)查(cha)、更換(huan)這些(xie)元(yuan)件(jian)(jian)后(hou)才能(neng)通電(dian)。

三、嚴重發熱，甚至有外殼燒化變形現象

這主要是部分用(yong)戶經常隨車攜(xie)帶造成(cheng)部分元器件松動引起的(de)故(gu)障(zhang)。主要表現為：C18松動虛焊時，會造成(cheng)V1、V2工作狀(zhuang)態(tai)不(bu)正常，熱量(liang)很大(da)，嚴(yan)重時充電(dian)器外殼(ke)變(bian)形(xing)，電(dian)路(lu)板燒焦，導致V1、V2損壞，可將C18重新焊接好，檢查V1、V2、R4、R7。如仍不(bu)能排(pai)除故(gu)障(zhang)，則需(xu)檢查D15、D21中(zhong)是否有一(yi)只開路(lu)，另外，有些廠家的(de)輸出整流管(guan)采(cai)用(yong)一(yi)只雙二極管(guan)，其中(zhong)一(yi)只開路(lu)亦造成(cheng)上述(shu)故(gu)障(zhang)，有時該故(gu)障(zhang)會造成(cheng)V1、V2中(zhong)一(yi)只損壞。需(xu)同時檢查及更換。

四、發熱量大且伴有異常響聲

故障原(yuan)因是(shi)輸出(chu)級消振阻(zu)容R31、C17損壞所致。另外，C12開路(lu)或虛焊(han)也會引起上(shang)述故障。

五、工作時有異常響聲，充不進電

檢查電路板上C8是否有(you)虛焊或損壞，一(yi)般更換C8均(jun)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)因是(shi)IC1損壞，更(geng)換時(shi)務必小心，不(bu)要(yao)將印制(zhi)板銅箔損壞，更(geng)換正常后(hou)，需(xu)調整R28使充電器輸出(chu)電壓在正常工作范圍內(nei)。

七、輸出電壓很高

輸出(chu)電(dian)(dian)壓很高（大于50V），其故(gu)障原因(yin)是C15短路或R26開路，具體判斷時可測量IC1集成電(dian)(dian)路的(de)“1”腳電(dian)(dian)壓。

注：更(geng)換R26后，應重新調整R28使充電器(qi)輸出電壓(ya)保持(chi)正常(chang)。

八、輸出電壓正常，但充電電流很小

檢查R30、R11、R13是否(fou)接(jie)觸不良(liang)或損壞(huai)，如正常請更換IC1即(ji)可排除故(gu)障。

九、輸出電壓正常，充電指示燈無指示或指示不正確

通常是(shi)由于IC2損壞或LED2損壞，可更換。

十、輸出部分銅箔燒斷

打(da)開充電器(qi)(qi)(qi)后(hou)發現(xian)充電器(qi)(qi)(qi)輸出(chu)部分銅(tong)箔燒斷，這通(tong)常是將電池正負極反接的結果，由此(ci)而引起的故障(zhang)將會導致充電器(qi)(qi)(qi)許(xu)多(duo)元件損(sun)(sun)壞。如果充電器(qi)(qi)(qi)保(bao)險絲(si)沒有壞，則通(tong)常更(geng)換(huan)R30、IC1、IC2后(hou)將斷銅(tong)箔連(lian)上即(ji)可(ke)恢復正常。如果充電器(qi)(qi)(qi)的保(bao)險絲(si)已斷，則故障(zhang)較(jiao)嚴重D1-D4、V1-V2、R4、R7等(deng)均有可(ke)能損(sun)(sun)壞，需測量后(hou)逐(zhu)一更(geng)換(huan)。

5、吱(zhi)吱(zhi)叫，發(fa)熱，充電(dian)(dian)不足(zu)：通(tong)電(dian)(dian)測(ce)量大電(dian)(dian)容(rong)電(dian)(dian)壓，只要低(di)于300V，一般(ban)電(dian)(dian)容(rong)失效，更換即可。

12、通(tong)電亮2個紅燈：通(tong)電試機，空載電壓(ya)是否正常，然(ran)后(hou)將358或324換新(xin)試機。

13、通電無輸出，能正(zheng)常啟(qi)動，指示燈(deng)正(zheng)常，先將輸出線換新，對于有繼電器的充電器直接短(duan)路繼電器試機。

14、通電閃燈(deng)，請(qing)補焊變壓器各引腳，然后試機，如果依(yi)舊(jiu)，請(qing)檢查431、光電耦合(he)器、輸出(chu)部分(fen)各二極管是(shi)否短路，變壓器磁芯是(shi)否松動，電源輸入部分(fen)10歐(ou)小電阻是(shi)否開路。或代換3842再次試機。

20、以上故障(zhang)適合于(yu)市場上大(da)部分單管電路(lu)充電器常見(jian)故障(zhang)，操作過程(cheng)中可隨時咨詢技(ji)術人員。

如(ru)48V充電(dian)(dian)(dian)器，最高電(dian)(dian)(dian)壓(ya)不(bu)(bu)大(da)于(yu)59.6V，大(da)于(yu)此電(dian)(dian)(dian)壓(ya)，充電(dian)(dian)(dian)可能不(bu)(bu)轉燈(deng)，低電(dian)(dian)(dian)壓(ya)不(bu)(bu)低于(yu)55V，低于(yu)此電(dian)(dian)(dian)壓(ya)造(zao)成充電(dian)(dian)(dian)不(bu)(bu)足，長(chang)時間容易對電(dian)(dian)(dian)池虧電(dian)(dian)(dian)。 電(dian)(dian)(dian)流，如(ru)48V20A充電(dian)(dian)(dian)器，最大(da)電(dian)(dian)(dian)流不(bu)(bu)大(da)于(yu)3A。大(da)于(yu)3A可能造(zao)成電(dian)(dian)(dian)池失水較(jiao)早，最低不(bu)(bu)低于(yu)2.1A。低壓(ya)此電(dian)(dian)(dian)流造(zao)成充電(dian)(dian)(dian)不(bu)(bu)足。

1、48V新電(dian)(dian)(dian)(dian)池要求充(chong)電(dian)(dian)(dian)(dian)器參數，最高(gao)(gao)電(dian)(dian)(dian)(dian)壓(ya)58.5---59.7，不低于58V，低于58V造成(cheng)充(chong)電(dian)(dian)(dian)(dian)不足，高(gao)(gao)于59.7V可能造成(cheng)充(chong)電(dian)(dian)(dian)(dian)不轉燈。轉燈電(dian)(dian)(dian)(dian)流約0.4---0.7A，實際電(dian)(dian)(dian)(dian)壓(ya)約55.5V，低于50V造成(cheng)充(chong)電(dian)(dian)(dian)(dian)不足，長(chang)時間充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池虧電(dian)(dian)(dian)(dian)。

2、4820電池要求充電最大電流2.4----3.3A，低(di)于2.2A充電慢，充電效果差。

3、市(shi)場上低于30元的充電器實際功率(lv)小(xiao)，參(can)數設計不精確，請(qing)注意(yi)區(qu)分。

4、充電(dian)器穩(wen)壓(ya)(ya)電(dian)路失效會(hui)造成輸出電(dian)壓(ya)(ya)75---130V，充電(dian)電(dian)池滾燙不轉燈。

5、當新電池出現(xian)，續航里(li)程20A電池低(di)于30公(gong)里(li)，12A電池低(di)于25公(gong)里(li)請檢查充(chong)電器(qi)各項(xiang)參數，如果無法判斷是，請更換優質充(chong)電器(qi)再次使用，即可解決問(wen)題。

6、新電池遇到不轉燈(deng)時，請(qing)更換另(ling)外一個優(you)質充電器試機。

7、正(zheng)常情況(kuang)下。4820新電池充(chong)(chong)電時(shi)間約10小時(shi)左右(you)，續航里程40---60公里，4812新電池充(chong)(chong)電時(shi)間約10小時(shi)內，里程達到25---40公里，如果正(zheng)常充(chong)(chong)電時(shi)間超過以上(shang)，請更換優質充(chong)(chong)電器再次使(shi)用。

8、有(you)(you)很多充(chong)電器(qi)內部電路、輸入輸出連線老(lao)化，造(zao)成，有(you)(you)時(shi)候能充(chong)、有(you)(you)時(shi)候不能沖。嚴(yan)重影響電池，或者充(chong)電過程中電路失(shi)效，造(zao)成充(chong)鼓包(bao)，如果出現(xian)這種(zhong)情況，請直(zhi)接(jie)更換優(you)質充(chong)電器(qi)再(zai)次使(shi)用。

很多朋友都在問電動車充電器可不(bu)可以(yi)(yi)通用(yong)這個問題。有(you)回(hui)答可以(yi)(yi)的(de)，有(you)對(dui)答不(bu)可以(yi)(yi)的(de)。那到底聽誰的(de)呢？買購網建(jian)議：最好用(yong)與電(dian)(dian)(dian)(dian)動(dong)車(che)(che)(che)(che)電(dian)(dian)(dian)(dian)池配套的(de)充(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)。因為一般情(qing)況(kuang)下(xia)，充(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)是(shi)(shi)(shi)根據電(dian)(dian)(dian)(dian)動(dong)車(che)(che)(che)(che)電(dian)(dian)(dian)(dian)池大(da)小(xiao)配置的(de)，也就(jiu)是(shi)(shi)(shi)說電(dian)(dian)(dian)(dian)流(liu)大(da)小(xiao)和電(dian)(dian)(dian)(dian)壓(ya)大(da)小(xiao)的(de)配置的(de)。正常情(qing)況(kuang)下(xia)電(dian)(dian)(dian)(dian)動(dong)車(che)(che)(che)(che)，四輪電(dian)(dian)(dian)(dian)動(dong)車(che)(che)(che)(che)，電(dian)(dian)(dian)(dian)動(dong)觀(guan)光車(che)(che)(che)(che)電(dian)(dian)(dian)(dian)動(dong)巡邏車(che)(che)(che)(che)都(dou)是(shi)(shi)(shi)18v或(huo)者72v都(dou)是(shi)(shi)(shi)有(you)一定規(gui)格的(de)。但是(shi)(shi)(shi)電(dian)(dian)(dian)(dian)動(dong)車(che)(che)(che)(che)電(dian)(dian)(dian)(dian)池的(de)容量單位不(bu)一定相同(tong)。所以(yi)(yi)建(jian)議大(da)家最好是(shi)(shi)(shi)使用(yong)配套的(de)電(dian)(dian)(dian)(dian)動(dong)車(che)(che)(che)(che)充(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)。當然了，我們知道電(dian)(dian)(dian)(dian)池被充(chong)壞跟充(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)電(dian)(dian)(dian)(dian)壓(ya)有(you)關而不(bu)是(shi)(shi)(shi)跟電(dian)(dian)(dian)(dian)流(liu)有(you)關。充(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)長時間不(bu)轉換或(huo)者充(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)電(dian)(dian)(dian)(dian)壓(ya)過高會導(dao)致電(dian)(dian)(dian)(dian)池失(shi)水，電(dian)(dian)(dian)(dian)池鼓包等情(qing)況(kuang)發生。電(dian)(dian)(dian)(dian)流(liu)對(dui)電(dian)(dian)(dian)(dian)池的(de)影響是(shi)(shi)(shi)對(dui)電(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)的(de)快慢而已。但是(shi)(shi)(shi)會充(chong)壞電(dian)(dian)(dian)(dian)動(dong)車(che)(che)(che)(che)電(dian)(dian)(dian)(dian)池。所以(yi)(yi)說電(dian)(dian)(dian)(dian)動(dong)車(che)(che)(che)(che)充(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)不(bu)是(shi)(shi)(shi)不(bu)可以(yi)(yi)通用(yong)，而是(shi)(shi)(shi)最好不(bu)要通用(yong)。
