一、充電時電源指示燈亮，充電指示燈橙色

首(shou)先請檢查一下(xia)(xia)充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)(qi)輸(shu)出(chu)插頭(tou)與電(dian)(dian)(dian)池(chi)盒的(de)充(chong)(chong)電(dian)(dian)(dian)插頭(tou)有(you)(you)(you)沒(mei)有(you)(you)(you)插緊。如(ru)確定沒(mei)有(you)(you)(you)問題，可(ke)檢查一下(xia)(xia)電(dian)(dian)(dian)池(chi)盒上(shang)面的(de)保險絲管是(shi)否開(kai)路或(huo)保險絲座有(you)(you)(you)松動接觸不(bu)良現象。另外(wai)，有(you)(you)(you)的(de)車(che)型要(yao)(yao)把電(dian)(dian)(dian)池(chi)鎖打開(kai)后才(cai)能充(chong)(chong)電(dian)(dian)(dian)。如(ru)果(guo)以上(shang)故障(zhang)均排除(chu)，考慮(lv)一下(xia)(xia)充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)(qi)輸(shu)出(chu)線是(shi)否開(kai)路，可(ke)用萬用表電(dian)(dian)(dian)壓擋(dang)（200V擋(dang)）測量一下(xia)(xia)充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)(qi)的(de)空載輸(shu)出(chu)電(dian)(dian)(dian)壓，應為41-44V（配36V電(dian)(dian)(dian)池(chi)因充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)(qi)不(bu)同有(you)(you)(you)所(suo)不(bu)同），如(ru)沒(mei)有(you)(you)(you)的(de)話(hua)，可(ke)能是(shi)充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)(qi)輸(shu)出(chu)線開(kai)路，并將(jiang)充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)(qi)打開(kai)，換(huan)一根輸(shu)出(chu)線，即可(ke)排除(chu)故障(zhang)。注(zhu)意：在(zai)更換(huan)充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)(qi)輸(shu)出(chu)線時，一定要(yao)(yao)注(zhu)意原機的(de)正負極不(bu)要(yao)(yao)接反(fan)。

二、電源指示燈不亮，充電指示燈也不亮

檢(jian)查(cha)充(chong)電(dian)(dian)器輸(shu)入電(dian)(dian)源(yuan)插頭與市電(dian)(dian)有(you)沒(mei)(mei)有(you)連接好，可將充(chong)電(dian)(dian)器輸(shu)入插頭插至正常的(de)電(dian)(dian)源(yuan)插座(zuo)中試一(yi)(yi)下(xia)，如(ru)情況依舊，將充(chong)電(dian)(dian)器外殼打開，觀察一(yi)(yi)下(xia)機(ji)內(nei)保(bao)險絲(si)有(you)沒(mei)(mei)有(you)斷，如(ru)沒(mei)(mei)有(you)斷，先(xian)檢(jian)查(cha)一(yi)(yi)下(xia)電(dian)(dian)源(yuan)輸(shu)入線是否良(liang)(liang)好，在排除(chu)電(dian)(dian)源(yuan)輸(shu)入線的(de)故障后(hou)，應檢(jian)查(cha)一(yi)(yi)下(xia)電(dian)(dian)路板上高壓(ya)區(qu)附(fu)近的(de)元(yuan)器件是否有(you)虛焊，保(bao)險絲(si)座(zuo)是否有(you)接觸不(bu)良(liang)(liang)現象(xiang)，重點(dian)檢(jian)查(cha)變(bian)壓(ya)器T1、三極(ji)管(guan)V1、V2等是否有(you)虛焊現象(xiang)。另外，R5或(huo)R6開路，也(ye)會(hui)引起上述故障，如(ru)機(ji)內(nei)保(bao)險絲(si)已(yi)斷，則(ze)千萬不(bu)要(yao)(yao)更換大(da)安培的(de)保(bao)險絲(si)管(guan)（充(chong)電(dian)(dian)器的(de)保(bao)險絲(si)管(guan)一(yi)(yi)般為(wei)2A），應重點(dian)檢(jian)查(cha)D1-D4、V1、V2、R4、R7及D15、D21有(you)無損(sun)壞(huai)，如(ru)有(you)損(sun)壞(huai)，可用(yong)同(tong)類型(xing)的(de)更換。請注意，上述元(yuan)件損(sun)壞(huai)時(shi)，可能(neng)會(hui)同(tong)時(shi)損(sun)壞(huai)一(yi)(yi)到二個，有(you)時(shi)可能(neng)會(hui)同(tong)時(shi)損(sun)壞(huai)好幾個，檢(jian)修時(shi)需要(yao)(yao)逐一(yi)(yi)檢(jian)查(cha)、更換這些元(yuan)件后(hou)才能(neng)通電(dian)(dian)。

三、嚴重發熱，甚至有外殼燒化變形現象

這主要是(shi)部(bu)分(fen)用戶經常(chang)隨車攜(xie)帶造(zao)(zao)(zao)(zao)成(cheng)部(bu)分(fen)元(yuan)器(qi)件松(song)(song)動引起(qi)的(de)故障。主要表現為：C18松(song)(song)動虛焊時，會造(zao)(zao)(zao)(zao)成(cheng)V1、V2工作狀態不正常(chang)，熱量很大(da)，嚴重(zhong)時充電器(qi)外殼變形，電路板(ban)燒焦，導致V1、V2損壞，可將C18重(zhong)新焊接好，檢(jian)(jian)查(cha)V1、V2、R4、R7。如仍不能排除故障，則需檢(jian)(jian)查(cha)D15、D21中是(shi)否有(you)一(yi)只開路，另外，有(you)些廠家的(de)輸出整流(liu)管采用一(yi)只雙二極管，其(qi)中一(yi)只開路亦造(zao)(zao)(zao)(zao)成(cheng)上述(shu)故障，有(you)時該故障會造(zao)(zao)(zao)(zao)成(cheng)V1、V2中一(yi)只損壞。需同時檢(jian)(jian)查(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(chu)級(ji)消振阻容(rong)R31、C17損壞所致。另外，C12開路或虛焊也會引起(qi)上述(shu)故障(zhang)。

五、工作時有異常響聲，充不進電

檢查電(dian)路板上C8是否有虛焊(han)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

故障原因是(shi)IC1損壞(huai)，更換(huan)(huan)時(shi)務必小心，不要將(jiang)印制板銅(tong)箔損壞(huai)，更換(huan)(huan)正常后，需調整R28使充(chong)電器輸出電壓在正常工作范(fan)圍(wei)內(nei)。

七、輸出電壓很高

輸(shu)出電壓很高(gao)（大于50V），其故(gu)障原因是C15短路(lu)或R26開路(lu)，具體判斷時可測量IC1集成電路(lu)的“1”腳電壓。

注：更換(huan)R26后，應(ying)重新調(diao)整R28使充電(dian)器輸出電(dian)壓保持正常(chang)。

八、輸出電壓正常，但充電電流很小

檢(jian)查R30、R11、R13是(shi)否接觸不良(liang)或(huo)損壞，如正常請(qing)更換(huan)IC1即(ji)可排除故障(zhang)。

九、輸出電壓正常，充電指示燈無指示或指示不正確

通常是由于IC2損(sun)壞或LED2損(sun)壞，可更換(huan)。

十、輸出部分銅箔燒斷

打開充電器后(hou)發現充電器輸(shu)出部分銅箔(bo)燒斷，這通(tong)常(chang)是將(jiang)電池正負極反接(jie)的(de)結果，由此而引(yin)起(qi)的(de)故障(zhang)將(jiang)會導致充電器許(xu)多元件損壞。如(ru)果充電器保險絲沒有壞，則通(tong)常(chang)更(geng)換R30、IC1、IC2后(hou)將(jiang)斷銅箔(bo)連上即可恢復正常(chang)。如(ru)果充電器的(de)保險絲已斷，則故障(zhang)較嚴重D1-D4、V1-V2、R4、R7等均(jun)有可能損壞，需測(ce)量后(hou)逐(zhu)一更(geng)換。

4、輸出(chu)電(dian)壓(ya)(ya)高，通電(dian)，電(dian)壓(ya)(ya)高于70多(duo)V，充電(dian)不轉燈(deng)，先將電(dian)路板補(bu)焊(han)一遍，再次試機，如果還(huan)是電(dian)壓(ya)(ya)高，請更(geng)換(huan)光電(dian)耦合器(qi)(qi)、再次試機、還(huan)是輸出(chu)高，更(geng)換(huan)431基準穩壓(ya)(ya)器(qi)(qi)，再次試機。

5、吱吱叫(jiao)，發熱，充電(dian)(dian)不(bu)足：通電(dian)(dian)測量大電(dian)(dian)容電(dian)(dian)壓，只要(yao)低于300V，一般(ban)電(dian)(dian)容失效(xiao)，更換即可。

6、嚴重發熱，請將風扇換新即(ji)可。

20、以上故(gu)障適(shi)合于市場上大部(bu)分單管電(dian)路充(chong)電(dian)器常見(jian)故(gu)障，操作過程中可隨時咨(zi)詢技術人(ren)員。

如(ru)(ru)48V充(chong)電(dian)器，最高電(dian)壓(ya)不(bu)(bu)大于(yu)59.6V，大于(yu)此電(dian)壓(ya)，充(chong)電(dian)可能(neng)不(bu)(bu)轉燈，低(di)(di)(di)電(dian)壓(ya)不(bu)(bu)低(di)(di)(di)于(yu)55V，低(di)(di)(di)于(yu)此電(dian)壓(ya)造(zao)成充(chong)電(dian)不(bu)(bu)足(zu)，長時間(jian)容(rong)易對(dui)電(dian)池(chi)(chi)虧電(dian)。 電(dian)流(liu)(liu)，如(ru)(ru)48V20A充(chong)電(dian)器，最大電(dian)流(liu)(liu)不(bu)(bu)大于(yu)3A。大于(yu)3A可能(neng)造(zao)成電(dian)池(chi)(chi)失(shi)水較早，最低(di)(di)(di)不(bu)(bu)低(di)(di)(di)于(yu)2.1A。低(di)(di)(di)壓(ya)此電(dian)流(liu)(liu)造(zao)成充(chong)電(dian)不(bu)(bu)足(zu)。

1、48V新(xin)電(dian)(dian)池要求充(chong)電(dian)(dian)器(qi)參數(shu)，最高電(dian)(dian)壓58.5---59.7，不低于58V，低于58V造(zao)成充(chong)電(dian)(dian)不足(zu)，高于59.7V可能造(zao)成充(chong)電(dian)(dian)不轉燈。轉燈電(dian)(dian)流約0.4---0.7A，實(shi)際電(dian)(dian)壓約55.5V，低于50V造(zao)成充(chong)電(dian)(dian)不足(zu)，長時間充(chong)電(dian)(dian)電(dian)(dian)池虧電(dian)(dian)。

2、4820電池要求(qiu)充(chong)(chong)電最大(da)電流2.4----3.3A，低于2.2A充(chong)(chong)電慢，充(chong)(chong)電效(xiao)果差。

3、市場(chang)上低于30元(yuan)的充(chong)電器(qi)實(shi)際功率小(xiao)，參數設(she)計不精確，請(qing)注意區分(fen)。

4、充電(dian)(dian)器穩(wen)壓電(dian)(dian)路失效會(hui)造成輸(shu)出(chu)電(dian)(dian)壓75---130V，充電(dian)(dian)電(dian)(dian)池滾燙不轉燈。

5、當新電池(chi)出(chu)現，續(xu)航(hang)里(li)程20A電池(chi)低(di)于30公里(li)，12A電池(chi)低(di)于25公里(li)請檢查充電器各(ge)項(xiang)參數(shu)，如果無(wu)法(fa)判斷是，請更換優(you)質充電器再(zai)次(ci)使(shi)用(yong)，即可解決問題。

6、新(xin)電池遇(yu)到不轉燈時，請更換另外一個優(you)質充電器試機。

7、正常情況(kuang)下(xia)。4820新(xin)電(dian)(dian)池充(chong)(chong)電(dian)(dian)時(shi)(shi)間約(yue)10小時(shi)(shi)左(zuo)右，續(xu)航里程40---60公(gong)里，4812新(xin)電(dian)(dian)池充(chong)(chong)電(dian)(dian)時(shi)(shi)間約(yue)10小時(shi)(shi)內，里程達到25---40公(gong)里，如果正常充(chong)(chong)電(dian)(dian)時(shi)(shi)間超(chao)過以上，請更換(huan)優質充(chong)(chong)電(dian)(dian)器再次使用(yong)。

8、有(you)很多充(chong)(chong)電(dian)(dian)器內部電(dian)(dian)路、輸入輸出(chu)連(lian)線老(lao)化，造成，有(you)時候能充(chong)(chong)、有(you)時候不能沖。嚴(yan)重影響(xiang)電(dian)(dian)池，或者充(chong)(chong)電(dian)(dian)過程中電(dian)(dian)路失效，造成充(chong)(chong)鼓包，如果出(chu)現這(zhe)種情況(kuang)，請直接更換優質(zhi)充(chong)(chong)電(dian)(dian)器再次使用。

很多朋友都在問電動車充電器可(ke)(ke)(ke)不(bu)可(ke)(ke)(ke)以(yi)(yi)通用(yong)這個問(wen)題(ti)。有回(hui)答可(ke)(ke)(ke)以(yi)(yi)的，有對(dui)答不(bu)可(ke)(ke)(ke)以(yi)(yi)的。那到底(di)聽誰的呢(ni)？買購網建議(yi)：最好用(yong)與電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)車(che)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)配(pei)套(tao)的充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)。因為一般情況下，充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)是(shi)(shi)(shi)根據電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)車(che)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)大(da)小(xiao)配(pei)置(zhi)的，也就(jiu)是(shi)(shi)(shi)說(shuo)電(dian)(dian)(dian)(dian)(dian)(dian)流大(da)小(xiao)和電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)大(da)小(xiao)的配(pei)置(zhi)的。正常情況下電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)車(che)，四輪(lun)電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)車(che)，電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)觀光車(che)電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)巡邏車(che)都(dou)是(shi)(shi)(shi)18v或(huo)者72v都(dou)是(shi)(shi)(shi)有一定規格的。但是(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)車(che)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的容量單位不(bu)一定相同。所以(yi)(yi)建議(yi)大(da)家最好是(shi)(shi)(shi)使用(yong)配(pei)套(tao)的電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)車(che)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)。當(dang)然了，我們知道電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)被充(chong)(chong)(chong)(chong)壞(huai)跟充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)有關而不(bu)是(shi)(shi)(shi)跟電(dian)(dian)(dian)(dian)(dian)(dian)流有關。充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)長時間不(bu)轉(zhuan)換或(huo)者充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)過高(gao)會(hui)導致(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)失水，電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)鼓包(bao)等情況發(fa)生。電(dian)(dian)(dian)(dian)(dian)(dian)流對(dui)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的影(ying)響是(shi)(shi)(shi)對(dui)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)的快慢而已。但是(shi)(shi)(shi)會(hui)充(chong)(chong)(chong)(chong)壞(huai)電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)車(che)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)。所以(yi)(yi)說(shuo)電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)車(che)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)不(bu)是(shi)(shi)(shi)不(bu)可(ke)(ke)(ke)以(yi)(yi)通用(yong)，而是(shi)(shi)(shi)最好不(bu)要通用(yong)。
