一、充電時電源指示燈亮，充電指示燈橙色

首先請檢(jian)查(cha)(cha)一(yi)下(xia)(xia)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)器(qi)輸(shu)出(chu)(chu)插(cha)頭與電(dian)(dian)池盒的(de)(de)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)插(cha)頭有(you)(you)(you)沒(mei)(mei)有(you)(you)(you)插(cha)緊。如(ru)確定沒(mei)(mei)有(you)(you)(you)問題(ti)，可(ke)檢(jian)查(cha)(cha)一(yi)下(xia)(xia)電(dian)(dian)池盒上面的(de)(de)保險絲(si)管是否開路或保險絲(si)座有(you)(you)(you)松動接觸不良現象。另外，有(you)(you)(you)的(de)(de)車型(xing)要(yao)(yao)(yao)把電(dian)(dian)池鎖打(da)開后(hou)才能充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)。如(ru)果以上故(gu)障均排(pai)除，考慮一(yi)下(xia)(xia)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)器(qi)輸(shu)出(chu)(chu)線(xian)是否開路，可(ke)用萬用表電(dian)(dian)壓擋（200V擋）測量一(yi)下(xia)(xia)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)器(qi)的(de)(de)空載輸(shu)出(chu)(chu)電(dian)(dian)壓，應為41-44V（配36V電(dian)(dian)池因(yin)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)器(qi)不同有(you)(you)(you)所不同），如(ru)沒(mei)(mei)有(you)(you)(you)的(de)(de)話，可(ke)能是充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)器(qi)輸(shu)出(chu)(chu)線(xian)開路，并(bing)將充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)器(qi)打(da)開，換(huan)一(yi)根輸(shu)出(chu)(chu)線(xian)，即可(ke)排(pai)除故(gu)障。注意(yi)：在更換(huan)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)器(qi)輸(shu)出(chu)(chu)線(xian)時，一(yi)定要(yao)(yao)(yao)注意(yi)原機的(de)(de)正負極不要(yao)(yao)(yao)接反。

二、電源指示燈不亮，充電指示燈也不亮

檢查(cha)(cha)充電(dian)器輸(shu)入電(dian)源(yuan)插頭與市電(dian)有(you)(you)沒有(you)(you)連接好，可(ke)將充電(dian)器輸(shu)入插頭插至(zhi)正常(chang)的(de)(de)(de)電(dian)源(yuan)插座中(zhong)試(shi)一(yi)(yi)(yi)下(xia)，如情況依舊，將充電(dian)器外(wai)殼打開，觀察一(yi)(yi)(yi)下(xia)機內(nei)保險(xian)絲(si)(si)有(you)(you)沒有(you)(you)斷(duan)，如沒有(you)(you)斷(duan)，先檢查(cha)(cha)一(yi)(yi)(yi)下(xia)電(dian)源(yuan)輸(shu)入線是(shi)否(fou)(fou)良(liang)好，在排除電(dian)源(yuan)輸(shu)入線的(de)(de)(de)故障(zhang)后，應(ying)(ying)檢查(cha)(cha)一(yi)(yi)(yi)下(xia)電(dian)路(lu)板上高壓區附近(jin)的(de)(de)(de)元器件是(shi)否(fou)(fou)有(you)(you)虛(xu)焊，保險(xian)絲(si)(si)座是(shi)否(fou)(fou)有(you)(you)接觸不良(liang)現象(xiang)，重點檢查(cha)(cha)變壓器T1、三極管V1、V2等是(shi)否(fou)(fou)有(you)(you)虛(xu)焊現象(xiang)。另外(wai)，R5或R6開路(lu)，也會(hui)引起上述故障(zhang)，如機內(nei)保險(xian)絲(si)(si)已斷(duan)，則千(qian)萬不要(yao)更(geng)換(huan)大安培的(de)(de)(de)保險(xian)絲(si)(si)管（充電(dian)器的(de)(de)(de)保險(xian)絲(si)(si)管一(yi)(yi)(yi)般(ban)為2A），應(ying)(ying)重點檢查(cha)(cha)D1-D4、V1、V2、R4、R7及D15、D21有(you)(you)無損(sun)壞，如有(you)(you)損(sun)壞，可(ke)用(yong)同(tong)類(lei)型的(de)(de)(de)更(geng)換(huan)。請(qing)注意，上述元件損(sun)壞時，可(ke)能(neng)(neng)會(hui)同(tong)時損(sun)壞一(yi)(yi)(yi)到(dao)二個(ge)，有(you)(you)時可(ke)能(neng)(neng)會(hui)同(tong)時損(sun)壞好幾(ji)個(ge)，檢修時需要(yao)逐一(yi)(yi)(yi)檢查(cha)(cha)、更(geng)換(huan)這(zhe)些元件后才能(neng)(neng)通電(dian)。

三、嚴重發熱，甚至有外殼燒化變形現象

這主要(yao)是部分用(yong)戶(hu)經常隨車攜(xie)帶造成(cheng)部分元器件松(song)動引(yin)起(qi)的故(gu)障。主要(yao)表現為：C18松(song)動虛焊時(shi)，會造成(cheng)V1、V2工作狀態不正常，熱量很大，嚴重時(shi)充電(dian)器外(wai)殼變形，電(dian)路(lu)板燒焦(jiao)，導(dao)致V1、V2損壞(huai)，可將C18重新焊接好，檢查V1、V2、R4、R7。如仍不能排除故(gu)障，則需檢查D15、D21中是否有(you)一(yi)只(zhi)(zhi)(zhi)開路(lu)，另(ling)外(wai)，有(you)些(xie)廠(chang)家(jia)的輸出整流管(guan)采(cai)用(yong)一(yi)只(zhi)(zhi)(zhi)雙二極管(guan)，其中一(yi)只(zhi)(zhi)(zhi)開路(lu)亦造成(cheng)上述故(gu)障，有(you)時(shi)該(gai)故(gu)障會造成(cheng)V1、V2中一(yi)只(zhi)(zhi)(zhi)損壞(huai)。需同時(shi)檢查及(ji)更換。

四、發熱量大且伴有異常響聲

故障原因是輸(shu)出級消振阻(zu)容R31、C17損壞(huai)所致。另外，C12開(kai)路或虛焊(han)也(ye)會引(yin)起上述故障。

五、工作時有異常響聲，充不進電

檢查電路(lu)板上C8是(shi)否有虛(xu)焊或損(sun)壞，一般更換C8均能(neng)解(jie)決(jue)。

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(zhang)原因是IC1損壞，更換(huan)時務必小心，不(bu)要將印制板銅箔(bo)損壞，更換(huan)正常后(hou)，需調整R28使充電器輸出(chu)電壓在正常工(gong)作范圍內。

七、輸出電壓很高

輸出電壓(ya)很高（大于50V），其故障原因是C15短路或R26開路，具體判(pan)斷時可測量IC1集成電路的“1”腳電壓(ya)。

注：更換R26后，應重(zhong)新調整(zheng)R28使充電器輸出電壓保持正(zheng)常(chang)。

八、輸出電壓正常，但充電電流很小

檢查R30、R11、R13是否接觸不良或損壞，如正常請更(geng)換(huan)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

通常是由于IC2損壞(huai)或LED2損壞(huai)，可更換。

十、輸出部分銅箔燒斷

打開充(chong)電(dian)(dian)器(qi)(qi)后發現充(chong)電(dian)(dian)器(qi)(qi)輸出部(bu)分銅箔燒斷，這通常是將(jiang)電(dian)(dian)池(chi)正負極反接的(de)(de)結果(guo)，由(you)此而(er)引(yin)起(qi)的(de)(de)故障將(jiang)會(hui)導致充(chong)電(dian)(dian)器(qi)(qi)許多(duo)元件(jian)損壞(huai)。如(ru)果(guo)充(chong)電(dian)(dian)器(qi)(qi)保險絲沒有壞(huai)，則通常更(geng)換R30、IC1、IC2后將(jiang)斷銅箔連(lian)上即可恢復正常。如(ru)果(guo)充(chong)電(dian)(dian)器(qi)(qi)的(de)(de)保險絲已斷，則故障較嚴重D1-D4、V1-V2、R4、R7等均有可能損壞(huai)，需測量后逐一更(geng)換。

1、電(dian)(dian)(dian)源(yuan)(yuan)不啟(qi)(qi)動：插(cha)電(dian)(dian)(dian)源(yuan)(yuan)，大(da)電(dian)(dian)(dian)容有300V電(dian)(dian)(dian)壓(ya)、拔(ba)掉(diao)電(dian)(dian)(dian)源(yuan)(yuan)再(zai)次(ci)測量大(da)電(dian)(dian)(dian)容2端還是300V電(dian)(dian)(dian)壓(ya)不下降(jiang)。給電(dian)(dian)(dian)容放電(dian)(dian)(dian)后，將(jiang)啟(qi)(qi)動電(dian)(dian)(dian)阻換(huan)掉(diao)即可。啟(qi)(qi)動電(dian)(dian)(dian)阻在電(dian)(dian)(dian)源(yuan)(yuan)輸入部分(fen)，阻值150K，功率2W。

2、電(dian)(dian)(dian)源(yuan)不啟動：插電(dian)(dian)(dian)，大(da)電(dian)(dian)(dian)容2端(duan)有300V電(dian)(dian)(dian)壓，拔掉電(dian)(dian)(dian)源(yuan)，大(da)電(dian)(dian)(dian)容電(dian)(dian)(dian)壓慢慢下降，將電(dian)(dian)(dian)路板全部(bu)檢(jian)查是否有脫焊的現象(xiang)，補焊完(wan)成(cheng)后，將3842換成(cheng)新的，通電(dian)(dian)(dian)試機即可。

3、閃燈：先(xian)將電(dian)(dian)路板補焊(han)一遍，再次試機，如果(guo)還是閃燈，請檢查輸出(chu)端(duan)取樣電(dian)(dian)阻(zu)。0.1歐(ou)。3W功率。接在輸出(chu)線(xian)的負極端(duan)，將此電(dian)(dian)阻(zu)換新(xin)即可。

4、輸出(chu)(chu)電(dian)(dian)(dian)壓(ya)高(gao)，通電(dian)(dian)(dian)，電(dian)(dian)(dian)壓(ya)高(gao)于70多(duo)V，充電(dian)(dian)(dian)不轉燈，先將電(dian)(dian)(dian)路板補焊(han)一遍，再次(ci)試(shi)機，如(ru)果還(huan)(huan)是電(dian)(dian)(dian)壓(ya)高(gao)，請更換光電(dian)(dian)(dian)耦合器、再次(ci)試(shi)機、還(huan)(huan)是輸出(chu)(chu)高(gao)，更換431基準穩壓(ya)器，再次(ci)試(shi)機。

5、吱(zhi)吱(zhi)叫，發熱，充電(dian)(dian)(dian)不足：通電(dian)(dian)(dian)測(ce)量大(da)電(dian)(dian)(dian)容電(dian)(dian)(dian)壓，只要低(di)于(yu)300V，一般電(dian)(dian)(dian)容失(shi)效，更(geng)換即(ji)可。

6、嚴重發熱，請將(jiang)風扇(shan)換新即可。

7、輸(shu)出電(dian)(dian)壓(ya)不穩(wen)定(ding)，先將(jiang)電(dian)(dian)路板補焊(han)一(yi)遍(bian)，后試(shi)機，然后將(jiang)輸(shu)出端電(dian)(dian)容(rong)63V470UF電(dian)(dian)容(rong)換新試(shi)機即可。

8、充電不轉燈，用檢(jian)測儀(yi)測試各項數據，然(ran)后(hou)將(jiang)358或者324換新試機。

9、充電(dian)不(bu)穩定，有時候(hou)能(neng)充，有時候(hou)不(bu)能(neng)沖，用測試(shi)儀檢測各(ge)項數據，然后(hou)將輸(shu)入輸(shu)出電(dian)源(yuan)線，全部(bu)換新，補焊線路板試(shi)機(ji)。

10、通電燒(shao)保(bao)險：先(xian)檢測功率管(guan)擊穿沒(mei)有，沒(mei)有的(de)話(hua)將(jiang)4個整流二極管(guan)全部換新，試(shi)機。

11、通(tong)電(dian)無輸(shu)出，通(tong)電(dian)試(shi)機(ji)(ji)，大電(dian)容2端有300V電(dian)壓，且慢慢下降，首先檢測輸(shu)出端大二極管擊穿(chuan)沒有，補焊(han)，再次試(shi)機(ji)(ji)。

12、通(tong)(tong)電(dian)(dian)亮2個紅燈(deng)：通(tong)(tong)電(dian)(dian)試(shi)機(ji)，空載電(dian)(dian)壓是否(fou)正常，然(ran)后將358或(huo)324換新試(shi)機(ji)。

13、通電無輸出(chu)，能正(zheng)常啟動(dong)，指(zhi)示燈正(zheng)常，先將輸出(chu)線換(huan)新，對(dui)于有繼電器(qi)的充電器(qi)直(zhi)接短(duan)路繼電器(qi)試(shi)機。

14、通電閃燈(deng)，請補焊變壓器各(ge)引腳，然后試(shi)機(ji)，如(ru)果依舊，請檢查(cha)431、光電耦合器、輸出部(bu)分(fen)各(ge)二極管是(shi)否(fou)短路，變壓器磁(ci)芯是(shi)否(fou)松動，電源輸入(ru)部(bu)分(fen)10歐小電阻是(shi)否(fou)開(kai)路。或代(dai)換3842再次(ci)試(shi)機(ji)。

15、充電(dian)(dian)不轉燈，先用測試(shi)儀檢測各項數(shu)據，一般充新電(dian)(dian)池(chi)電(dian)(dian)壓不高(gao)于59.5，充半(ban)年左右電(dian)(dian)池(chi)不高(gao)于58.8，為正常，高(gao)于此電(dian)(dian)壓可能不轉燈。

16、輸(shu)出(chu)電(dian)(dian)壓低：補(bu)焊(han)線(xian)路板。試(shi)機，然后將(jiang)輸(shu)入輸(shu)出(chu)大電(dian)(dian)容換新再(zai)次(ci)試(shi)機。

17、輸出低(di)，發燙(tang)，如果輸出電(dian)壓(ya)低(di)于40多V，且功率管，變壓(ya)器(qi)(qi)發燙(tang)，一般為變壓(ya)器(qi)(qi)有問題。

18、啟動(dong)困難，有時(shi)候能起(qi)到有時(shi)候不能啟動(dong)，補焊線路板，后試機，如果依舊(jiu)請將輸入部分(fen)小電容換新再(zai)次試機，50V47UF。

19、燒(shao)3842,3842換新后試機插電(dian)(dian)(dian)聽(ting)到一(yi)聲喀的一(yi)聲響，這是測量大(da)電(dian)(dian)(dian)容(rong)2端電(dian)(dian)(dian)壓300V慢(man)(man)慢(man)(man)將(jiang)，說明3842又(you)擊穿了，先補(bu)焊(han)線(xian)路(lu)板(ban)，檢查變壓器(qi)引(yin)腳是否松動或者引(yin)線(xian)是否斷開，輸出(chu)部(bu)分大(da)二極管(guan)是否開路(lu)，線(xian)路(lu)板(ban)是否斷裂。

20、以(yi)上(shang)故(gu)障適合于(yu)市場上(shang)大部分單管電(dian)路充電(dian)器常見故(gu)障，操作過程中可隨時咨(zi)詢技術人員。

如48V充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器，最高電(dian)(dian)(dian)(dian)壓(ya)(ya)不(bu)大(da)于(yu)59.6V，大(da)于(yu)此電(dian)(dian)(dian)(dian)壓(ya)(ya)，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)可能(neng)不(bu)轉燈，低(di)(di)電(dian)(dian)(dian)(dian)壓(ya)(ya)不(bu)低(di)(di)于(yu)55V，低(di)(di)于(yu)此電(dian)(dian)(dian)(dian)壓(ya)(ya)造(zao)成(cheng)(cheng)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)不(bu)足，長(chang)時間容易對電(dian)(dian)(dian)(dian)池虧電(dian)(dian)(dian)(dian)。 電(dian)(dian)(dian)(dian)流，如48V20A充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器，最大(da)電(dian)(dian)(dian)(dian)流不(bu)大(da)于(yu)3A。大(da)于(yu)3A可能(neng)造(zao)成(cheng)(cheng)電(dian)(dian)(dian)(dian)池失水較早，最低(di)(di)不(bu)低(di)(di)于(yu)2.1A。低(di)(di)壓(ya)(ya)此電(dian)(dian)(dian)(dian)流造(zao)成(cheng)(cheng)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)不(bu)足。

1、48V新電池要求充(chong)(chong)電器參數，最(zui)高電壓58.5---59.7，不(bu)低于58V，低于58V造成充(chong)(chong)電不(bu)足，高于59.7V可能造成充(chong)(chong)電不(bu)轉(zhuan)燈。轉(zhuan)燈電流約(yue)0.4---0.7A，實際電壓約(yue)55.5V，低于50V造成充(chong)(chong)電不(bu)足，長時間(jian)充(chong)(chong)電電池虧電。

2、4820電(dian)池(chi)要(yao)求(qiu)充電(dian)最大(da)電(dian)流2.4----3.3A，低于2.2A充電(dian)慢，充電(dian)效果差(cha)。

3、市場上低(di)于30元的充電器實際功率小，參數(shu)設計不精確，請注(zhu)意(yi)區分。

4、充(chong)電(dian)器(qi)穩(wen)壓電(dian)路失效會(hui)造(zao)成輸出電(dian)壓75---130V，充(chong)電(dian)電(dian)池滾燙不轉(zhuan)燈。

5、當新電池(chi)出現，續航里程20A電池(chi)低于(yu)30公(gong)里，12A電池(chi)低于(yu)25公(gong)里請(qing)檢查充電器各項參數，如果無法判斷是，請(qing)更(geng)換優質充電器再次使用，即(ji)可解決問(wen)題。

6、新電(dian)池遇到(dao)不轉燈(deng)時，請更換另外一個優質(zhi)充電(dian)器試機。

7、正(zheng)常(chang)情(qing)況下。4820新(xin)電(dian)池(chi)(chi)充(chong)(chong)電(dian)時間(jian)約(yue)10小時左(zuo)右，續(xu)航里(li)程40---60公(gong)里(li)，4812新(xin)電(dian)池(chi)(chi)充(chong)(chong)電(dian)時間(jian)約(yue)10小時內，里(li)程達到25---40公(gong)里(li)，如果正(zheng)常(chang)充(chong)(chong)電(dian)時間(jian)超過以上(shang)，請更換優質充(chong)(chong)電(dian)器再次(ci)使(shi)用。

8、有(you)很多充電(dian)器(qi)內部電(dian)路(lu)、輸(shu)入輸(shu)出連(lian)線老化，造成(cheng)，有(you)時候能充、有(you)時候不能沖。嚴重(zhong)影響電(dian)池，或者充電(dian)過程(cheng)中電(dian)路(lu)失效，造成(cheng)充鼓包(bao)，如(ru)果出現(xian)這(zhe)種情況，請直接更換優質(zhi)充電(dian)器(qi)再次(ci)使用。

很多朋友都在問電動車充電器可(ke)(ke)不(bu)(bu)可(ke)(ke)以(yi)通用(yong)(yong)這個問題。有回答(da)可(ke)(ke)以(yi)的(de)(de)，有對答(da)不(bu)(bu)可(ke)(ke)以(yi)的(de)(de)。那到(dao)底聽誰的(de)(de)呢？買購網建(jian)議(yi)：最好用(yong)(yong)與電(dian)(dian)(dian)(dian)(dian)動(dong)車(che)(che)(che)(che)電(dian)(dian)(dian)(dian)(dian)池(chi)配套(tao)的(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)。因(yin)為一般情(qing)況下，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)是根據電(dian)(dian)(dian)(dian)(dian)動(dong)車(che)(che)(che)(che)電(dian)(dian)(dian)(dian)(dian)池(chi)大(da)小配置(zhi)的(de)(de)，也就(jiu)是說(shuo)電(dian)(dian)(dian)(dian)(dian)流大(da)小和電(dian)(dian)(dian)(dian)(dian)壓(ya)大(da)小的(de)(de)配置(zhi)的(de)(de)。正常(chang)情(qing)況下電(dian)(dian)(dian)(dian)(dian)動(dong)車(che)(che)(che)(che)，四輪電(dian)(dian)(dian)(dian)(dian)動(dong)車(che)(che)(che)(che)，電(dian)(dian)(dian)(dian)(dian)動(dong)觀(guan)光車(che)(che)(che)(che)電(dian)(dian)(dian)(dian)(dian)動(dong)巡邏車(che)(che)(che)(che)都是18v或(huo)者(zhe)72v都是有一定(ding)規格的(de)(de)。但是電(dian)(dian)(dian)(dian)(dian)動(dong)車(che)(che)(che)(che)電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)容量單位不(bu)(bu)一定(ding)相(xiang)同。所(suo)以(yi)建(jian)議(yi)大(da)家最好是使用(yong)(yong)配套(tao)的(de)(de)電(dian)(dian)(dian)(dian)(dian)動(dong)車(che)(che)(che)(che)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)。當然了，我們知道電(dian)(dian)(dian)(dian)(dian)池(chi)被充(chong)(chong)壞跟(gen)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)電(dian)(dian)(dian)(dian)(dian)壓(ya)有關而(er)不(bu)(bu)是跟(gen)電(dian)(dian)(dian)(dian)(dian)流有關。充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)長(chang)時間不(bu)(bu)轉換或(huo)者(zhe)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)電(dian)(dian)(dian)(dian)(dian)壓(ya)過高(gao)會導致電(dian)(dian)(dian)(dian)(dian)池(chi)失水，電(dian)(dian)(dian)(dian)(dian)池(chi)鼓(gu)包(bao)等情(qing)況發生。電(dian)(dian)(dian)(dian)(dian)流對電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)影響是對電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)的(de)(de)快慢而(er)已。但是會充(chong)(chong)壞電(dian)(dian)(dian)(dian)(dian)動(dong)車(che)(che)(che)(che)電(dian)(dian)(dian)(dian)(dian)池(chi)。所(suo)以(yi)說(shuo)電(dian)(dian)(dian)(dian)(dian)動(dong)車(che)(che)(che)(che)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)不(bu)(bu)是不(bu)(bu)可(ke)(ke)以(yi)通用(yong)(yong)，而(er)是最好不(bu)(bu)要(yao)通用(yong)(yong)。
