一、充電時電源指示燈亮，充電指示燈橙色

首先請(qing)檢查一(yi)(yi)下充(chong)電(dian)(dian)(dian)器(qi)(qi)輸(shu)(shu)出(chu)插頭(tou)與電(dian)(dian)(dian)池(chi)盒的(de)(de)充(chong)電(dian)(dian)(dian)插頭(tou)有(you)(you)沒有(you)(you)插緊(jin)。如確定沒有(you)(you)問題，可檢查一(yi)(yi)下電(dian)(dian)(dian)池(chi)盒上面的(de)(de)保險(xian)絲(si)管是否開(kai)(kai)路(lu)或保險(xian)絲(si)座有(you)(you)松動接觸不良(liang)現象。另(ling)外，有(you)(you)的(de)(de)車型要把電(dian)(dian)(dian)池(chi)鎖(suo)打開(kai)(kai)后才能(neng)充(chong)電(dian)(dian)(dian)。如果(guo)以(yi)上故障(zhang)均(jun)排(pai)(pai)除，考慮一(yi)(yi)下充(chong)電(dian)(dian)(dian)器(qi)(qi)輸(shu)(shu)出(chu)線(xian)(xian)是否開(kai)(kai)路(lu)，可用萬(wan)用表(biao)電(dian)(dian)(dian)壓(ya)擋(dang)（200V擋(dang)）測(ce)量一(yi)(yi)下充(chong)電(dian)(dian)(dian)器(qi)(qi)的(de)(de)空載輸(shu)(shu)出(chu)電(dian)(dian)(dian)壓(ya)，應為41-44V（配(pei)36V電(dian)(dian)(dian)池(chi)因(yin)充(chong)電(dian)(dian)(dian)器(qi)(qi)不同(tong)有(you)(you)所不同(tong)），如沒有(you)(you)的(de)(de)話(hua)，可能(neng)是充(chong)電(dian)(dian)(dian)器(qi)(qi)輸(shu)(shu)出(chu)線(xian)(xian)開(kai)(kai)路(lu)，并(bing)將充(chong)電(dian)(dian)(dian)器(qi)(qi)打開(kai)(kai)，換(huan)一(yi)(yi)根輸(shu)(shu)出(chu)線(xian)(xian)，即可排(pai)(pai)除故障(zhang)。注意：在更換(huan)充(chong)電(dian)(dian)(dian)器(qi)(qi)輸(shu)(shu)出(chu)線(xian)(xian)時，一(yi)(yi)定要注意原機的(de)(de)正(zheng)負極不要接反(fan)。

二、電源指示燈不亮，充電指示燈也不亮

檢(jian)(jian)查充電(dian)(dian)(dian)(dian)(dian)器輸(shu)入(ru)電(dian)(dian)(dian)(dian)(dian)源(yuan)插(cha)頭與(yu)市(shi)電(dian)(dian)(dian)(dian)(dian)有(you)沒(mei)有(you)連(lian)接好(hao)，可(ke)將充電(dian)(dian)(dian)(dian)(dian)器輸(shu)入(ru)插(cha)頭插(cha)至正常的(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)插(cha)座中試一(yi)(yi)(yi)(yi)下，如(ru)情況依舊，將充電(dian)(dian)(dian)(dian)(dian)器外(wai)殼打開，觀察一(yi)(yi)(yi)(yi)下機內保(bao)險(xian)絲有(you)沒(mei)有(you)斷(duan)，如(ru)沒(mei)有(you)斷(duan)，先(xian)檢(jian)(jian)查一(yi)(yi)(yi)(yi)下電(dian)(dian)(dian)(dian)(dian)源(yuan)輸(shu)入(ru)線是否(fou)良好(hao)，在排除電(dian)(dian)(dian)(dian)(dian)源(yuan)輸(shu)入(ru)線的(de)(de)故障后(hou)，應(ying)檢(jian)(jian)查一(yi)(yi)(yi)(yi)下電(dian)(dian)(dian)(dian)(dian)路(lu)板上高壓(ya)區附近(jin)的(de)(de)元器件(jian)是否(fou)有(you)虛(xu)焊(han)，保(bao)險(xian)絲座是否(fou)有(you)接觸(chu)不(bu)良現(xian)象，重(zhong)點檢(jian)(jian)查變(bian)壓(ya)器T1、三極管V1、V2等是否(fou)有(you)虛(xu)焊(han)現(xian)象。另(ling)外(wai)，R5或R6開路(lu)，也(ye)會(hui)引(yin)起(qi)上述故障，如(ru)機內保(bao)險(xian)絲已(yi)斷(duan)，則(ze)千萬(wan)不(bu)要(yao)更(geng)換大安培的(de)(de)保(bao)險(xian)絲管（充電(dian)(dian)(dian)(dian)(dian)器的(de)(de)保(bao)險(xian)絲管一(yi)(yi)(yi)(yi)般為2A），應(ying)重(zhong)點檢(jian)(jian)查D1-D4、V1、V2、R4、R7及(ji)D15、D21有(you)無損(sun)(sun)壞(huai)(huai)，如(ru)有(you)損(sun)(sun)壞(huai)(huai)，可(ke)用同(tong)類型(xing)的(de)(de)更(geng)換。請注(zhu)意，上述元件(jian)損(sun)(sun)壞(huai)(huai)時(shi)，可(ke)能會(hui)同(tong)時(shi)損(sun)(sun)壞(huai)(huai)一(yi)(yi)(yi)(yi)到(dao)二(er)個，有(you)時(shi)可(ke)能會(hui)同(tong)時(shi)損(sun)(sun)壞(huai)(huai)好(hao)幾個，檢(jian)(jian)修時(shi)需要(yao)逐(zhu)一(yi)(yi)(yi)(yi)檢(jian)(jian)查、更(geng)換這些元件(jian)后(hou)才能通電(dian)(dian)(dian)(dian)(dian)。

三、嚴重發熱，甚至有外殼燒化變形現象

這主要是(shi)部分(fen)用(yong)戶(hu)經常隨車(che)攜帶造成部分(fen)元器(qi)件松動引起的故障。主要表現為：C18松動虛(xu)焊時，會(hui)(hui)造成V1、V2工(gong)作狀態不正常，熱量很大(da)，嚴(yan)重(zhong)時充電器(qi)外(wai)殼變形，電路板(ban)燒(shao)焦(jiao)，導致V1、V2損壞(huai)，可將(jiang)C18重(zhong)新焊接(jie)好，檢(jian)查V1、V2、R4、R7。如仍不能排除故障，則需檢(jian)查D15、D21中(zhong)是(shi)否(fou)有一只(zhi)開路，另(ling)外(wai)，有些廠家的輸出整(zheng)流管采(cai)用(yong)一只(zhi)雙二極管，其中(zhong)一只(zhi)開路亦(yi)造成上述故障，有時該故障會(hui)(hui)造成V1、V2中(zhong)一只(zhi)損壞(huai)。需同時檢(jian)查及(ji)更換。

四、發熱量大且伴有異常響聲

故障(zhang)原因是輸出級消振阻(zu)容R31、C17損壞所致。另外，C12開路或(huo)虛焊也會(hui)引起上述故障(zhang)。

五、工作時有異常響聲，充不進電

檢查(cha)電路板(ban)上C8是否有虛焊或(huo)損(sun)壞，一般更(geng)換C8均能解(jie)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IC1損(sun)壞(huai)，更(geng)換(huan)時務必(bi)小(xiao)心，不要將印制板銅箔損(sun)壞(huai)，更(geng)換(huan)正常后，需調整R28使充電器輸出電壓在正常工作范(fan)圍內。

七、輸出電壓很高

輸出(chu)電(dian)壓很(hen)高（大于(yu)50V），其故(gu)障原因是C15短路或(huo)R26開路，具體(ti)判斷時可(ke)測量IC1集成(cheng)電(dian)路的“1”腳(jiao)電(dian)壓。

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

八、輸出電壓正常，但充電電流很小

檢查R30、R11、R13是(shi)否接觸不良或損(sun)壞，如正常請更換(huan)IC1即可排除故障(zhang)。

九、輸出電壓正常，充電指示燈無指示或指示不正確

通(tong)常(chang)是由于IC2損壞或LED2損壞，可更換(huan)。

十、輸出部分銅箔燒斷

打開充(chong)電器(qi)后發現(xian)充(chong)電器(qi)輸出部分銅(tong)箔燒斷(duan)，這(zhe)通常(chang)(chang)是(shi)將電池(chi)正(zheng)負極(ji)反接(jie)的(de)結果(guo)(guo)，由此而引起的(de)故(gu)障將會導(dao)致充(chong)電器(qi)許多元(yuan)件(jian)損壞。如果(guo)(guo)充(chong)電器(qi)保(bao)險(xian)絲(si)沒有壞，則通常(chang)(chang)更(geng)(geng)換R30、IC1、IC2后將斷(duan)銅(tong)箔連上即可(ke)恢(hui)復正(zheng)常(chang)(chang)。如果(guo)(guo)充(chong)電器(qi)的(de)保(bao)險(xian)絲(si)已斷(duan)，則故(gu)障較嚴重D1-D4、V1-V2、R4、R7等均有可(ke)能損壞，需測量后逐一更(geng)(geng)換。

1、電(dian)(dian)(dian)源(yuan)(yuan)不(bu)啟動(dong)：插電(dian)(dian)(dian)源(yuan)(yuan)，大電(dian)(dian)(dian)容(rong)(rong)有(you)300V電(dian)(dian)(dian)壓(ya)、拔掉(diao)電(dian)(dian)(dian)源(yuan)(yuan)再次測量大電(dian)(dian)(dian)容(rong)(rong)2端還是(shi)300V電(dian)(dian)(dian)壓(ya)不(bu)下降(jiang)。給電(dian)(dian)(dian)容(rong)(rong)放電(dian)(dian)(dian)后，將(jiang)啟動(dong)電(dian)(dian)(dian)阻換掉(diao)即可。啟動(dong)電(dian)(dian)(dian)阻在電(dian)(dian)(dian)源(yuan)(yuan)輸入部分，阻值(zhi)150K，功率2W。

2、電(dian)(dian)(dian)源不啟動：插電(dian)(dian)(dian)，大電(dian)(dian)(dian)容2端有(you)300V電(dian)(dian)(dian)壓，拔(ba)掉電(dian)(dian)(dian)源，大電(dian)(dian)(dian)容電(dian)(dian)(dian)壓慢慢下降(jiang)，將(jiang)電(dian)(dian)(dian)路板全部檢查(cha)是否有(you)脫焊的現象，補焊完成(cheng)后，將(jiang)3842換成(cheng)新的，通電(dian)(dian)(dian)試機(ji)即可。

3、閃燈：先(xian)將(jiang)電路板補焊一遍，再次試機，如果還是閃燈，請檢查輸(shu)出端取(qu)樣電阻。0.1歐(ou)。3W功率。接在輸(shu)出線的負極(ji)端，將(jiang)此電阻換新即可。

4、輸出(chu)電(dian)(dian)壓(ya)(ya)(ya)高(gao)，通電(dian)(dian)，電(dian)(dian)壓(ya)(ya)(ya)高(gao)于70多V，充電(dian)(dian)不轉燈，先將電(dian)(dian)路(lu)板(ban)補焊(han)一(yi)遍，再次(ci)試機，如果還是電(dian)(dian)壓(ya)(ya)(ya)高(gao)，請更換(huan)光電(dian)(dian)耦合器、再次(ci)試機、還是輸出(chu)高(gao)，更換(huan)431基準穩壓(ya)(ya)(ya)器，再次(ci)試機。

5、吱吱叫(jiao)，發(fa)熱，充電(dian)(dian)不足：通(tong)電(dian)(dian)測量大電(dian)(dian)容(rong)電(dian)(dian)壓，只要低于300V，一般電(dian)(dian)容(rong)失效，更(geng)換即可(ke)。

6、嚴重發熱，請將風(feng)扇換新即(ji)可。

7、輸(shu)(shu)出電壓(ya)不穩定，先將(jiang)電路板(ban)補焊(han)一(yi)遍，后試機，然后將(jiang)輸(shu)(shu)出端電容(rong)63V470UF電容(rong)換(huan)新試機即(ji)可。

8、充電不轉燈，用檢測儀測試各項數據，然后將(jiang)358或者(zhe)324換新試機。

9、充(chong)電(dian)不穩定(ding)，有(you)時候能充(chong)，有(you)時候不能沖，用測試儀檢(jian)測各項數(shu)據，然(ran)后將輸(shu)入輸(shu)出電(dian)源線，全部換新，補焊線路板試機。

10、通電燒保(bao)險：先檢測功率(lv)管擊穿沒有，沒有的話(hua)將(jiang)4個整(zheng)流二(er)極管全部換新，試機。

11、通(tong)電(dian)(dian)無輸出，通(tong)電(dian)(dian)試機，大電(dian)(dian)容2端(duan)有(you)300V電(dian)(dian)壓，且慢慢下降，首先檢測輸出端(duan)大二(er)極管擊穿沒(mei)有(you)，補焊，再次試機。

12、通電(dian)亮2個紅燈：通電(dian)試機，空(kong)載電(dian)壓是否正常(chang)，然(ran)后將(jiang)358或(huo)324換新試機。

13、通電(dian)(dian)(dian)無(wu)輸出，能正常啟動(dong)，指示燈正常，先將輸出線換新，對于有繼電(dian)(dian)(dian)器(qi)的充電(dian)(dian)(dian)器(qi)直接短路繼電(dian)(dian)(dian)器(qi)試機。

14、通電(dian)(dian)(dian)閃燈，請補焊變壓(ya)器(qi)各(ge)引(yin)腳，然后試機(ji)，如果(guo)依舊，請檢查431、光電(dian)(dian)(dian)耦合(he)器(qi)、輸出部分各(ge)二極管是否(fou)(fou)短路，變壓(ya)器(qi)磁芯是否(fou)(fou)松動(dong)，電(dian)(dian)(dian)源(yuan)輸入(ru)部分10歐(ou)小電(dian)(dian)(dian)阻是否(fou)(fou)開路。或代換3842再(zai)次試機(ji)。

15、充電(dian)不轉(zhuan)燈，先(xian)用測試儀檢測各(ge)項數據，一般充新(xin)電(dian)池電(dian)壓不高(gao)(gao)于(yu)(yu)59.5，充半(ban)年左右電(dian)池不高(gao)(gao)于(yu)(yu)58.8，為正常(chang)，高(gao)(gao)于(yu)(yu)此電(dian)壓可能不轉(zhuan)燈。

16、輸出電(dian)(dian)壓低：補焊線路(lu)板。試(shi)機，然后將輸入輸出大電(dian)(dian)容(rong)換(huan)新再次(ci)試(shi)機。

17、輸出低(di)，發燙，如果(guo)輸出電壓低(di)于40多V，且功率(lv)管(guan)，變壓器發燙，一般為變壓器有問題。

18、啟(qi)動困難(nan)，有時候能(neng)起(qi)到有時候不能(neng)啟(qi)動，補焊線(xian)路板(ban)，后試機，如果依舊(jiu)請將輸入部(bu)分(fen)小電容(rong)換新再次試機，50V47UF。

19、燒(shao)3842,3842換新后(hou)試(shi)機插電聽到(dao)一聲喀的一聲響，這是測量大電容2端電壓(ya)300V慢(man)慢(man)將，說明3842又擊穿(chuan)了，先補焊線路(lu)(lu)板(ban)，檢查變壓(ya)器引腳是否(fou)松動或者(zhe)引線是否(fou)斷開(kai)，輸出部分大二極(ji)管是否(fou)開(kai)路(lu)(lu)，線路(lu)(lu)板(ban)是否(fou)斷裂。

20、以上故障(zhang)適合于市場上大部(bu)分單(dan)管電(dian)(dian)路(lu)充電(dian)(dian)器常見故障(zhang)，操(cao)作過程中可隨(sui)時咨詢技術人員。

如(ru)48V充(chong)(chong)電(dian)器(qi)，最(zui)高電(dian)壓(ya)不大(da)(da)于(yu)(yu)(yu)(yu)59.6V，大(da)(da)于(yu)(yu)(yu)(yu)此(ci)電(dian)壓(ya)，充(chong)(chong)電(dian)可(ke)能不轉燈，低電(dian)壓(ya)不低于(yu)(yu)(yu)(yu)55V，低于(yu)(yu)(yu)(yu)此(ci)電(dian)壓(ya)造(zao)成(cheng)充(chong)(chong)電(dian)不足，長時間(jian)容易(yi)對電(dian)池虧電(dian)。 電(dian)流(liu)，如(ru)48V20A充(chong)(chong)電(dian)器(qi)，最(zui)大(da)(da)電(dian)流(liu)不大(da)(da)于(yu)(yu)(yu)(yu)3A。大(da)(da)于(yu)(yu)(yu)(yu)3A可(ke)能造(zao)成(cheng)電(dian)池失(shi)水較(jiao)早，最(zui)低不低于(yu)(yu)(yu)(yu)2.1A。低壓(ya)此(ci)電(dian)流(liu)造(zao)成(cheng)充(chong)(chong)電(dian)不足。

1、48V新(xin)電(dian)(dian)池(chi)要求充電(dian)(dian)器參(can)數，最高電(dian)(dian)壓(ya)58.5---59.7，不(bu)低于(yu)(yu)58V，低于(yu)(yu)58V造成充電(dian)(dian)不(bu)足，高于(yu)(yu)59.7V可能(neng)造成充電(dian)(dian)不(bu)轉燈。轉燈電(dian)(dian)流約0.4---0.7A，實際電(dian)(dian)壓(ya)約55.5V，低于(yu)(yu)50V造成充電(dian)(dian)不(bu)足，長(chang)時間充電(dian)(dian)電(dian)(dian)池(chi)虧電(dian)(dian)。

2、4820電(dian)池要求充電(dian)最大電(dian)流(liu)2.4----3.3A，低于2.2A充電(dian)慢，充電(dian)效(xiao)果差。

3、市(shi)場(chang)上低于30元的充電器(qi)實際功率小(xiao)，參數設(she)計不精(jing)確，請注意(yi)區(qu)分。

4、充電器穩壓(ya)(ya)電路失效會造成(cheng)輸出電壓(ya)(ya)75---130V，充電電池滾燙不(bu)轉燈。

5、當新電池(chi)(chi)出(chu)現，續航(hang)里(li)程20A電池(chi)(chi)低于30公(gong)里(li)，12A電池(chi)(chi)低于25公(gong)里(li)請檢查充電器各項參(can)數，如果無法判斷是，請更換優質(zhi)充電器再次使(shi)用，即(ji)可解決問(wen)題。

6、新電(dian)(dian)池遇到不轉燈時，請更(geng)換另外一個優質充電(dian)(dian)器(qi)試機(ji)。

7、正常(chang)情(qing)況下。4820新(xin)電(dian)池充電(dian)時間約(yue)10小時左右，續航里程40---60公里，4812新(xin)電(dian)池充電(dian)時間約(yue)10小時內(nei)，里程達到25---40公里，如(ru)果(guo)正常(chang)充電(dian)時間超(chao)過以上(shang)，請更換優(you)質(zhi)充電(dian)器再次使用(yong)。

8、有很(hen)多充電(dian)(dian)(dian)器內部電(dian)(dian)(dian)路、輸入輸出連線(xian)老化(hua)，造(zao)(zao)成(cheng)，有時(shi)候能(neng)充、有時(shi)候不能(neng)沖。嚴重影響電(dian)(dian)(dian)池，或者充電(dian)(dian)(dian)過程中電(dian)(dian)(dian)路失效，造(zao)(zao)成(cheng)充鼓包，如(ru)果出現這種情況，請直接更換優質(zhi)充電(dian)(dian)(dian)器再次使用。

很多朋友都在問電動車充電器可(ke)(ke)不可(ke)(ke)以(yi)通(tong)用(yong)這(zhe)個問題。有(you)回答可(ke)(ke)以(yi)的(de)(de)(de)，有(you)對(dui)答不可(ke)(ke)以(yi)的(de)(de)(de)。那(nei)到底聽誰的(de)(de)(de)呢？買(mai)購網建議：最好(hao)(hao)用(yong)與電(dian)(dian)(dian)(dian)動(dong)(dong)車電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)配(pei)套的(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)。因為一般情(qing)(qing)(qing)況(kuang)(kuang)下(xia)，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)是(shi)根據電(dian)(dian)(dian)(dian)動(dong)(dong)車電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)大(da)(da)(da)小(xiao)配(pei)置(zhi)的(de)(de)(de)，也就是(shi)說電(dian)(dian)(dian)(dian)流大(da)(da)(da)小(xiao)和電(dian)(dian)(dian)(dian)壓大(da)(da)(da)小(xiao)的(de)(de)(de)配(pei)置(zhi)的(de)(de)(de)。正常(chang)情(qing)(qing)(qing)況(kuang)(kuang)下(xia)電(dian)(dian)(dian)(dian)動(dong)(dong)車，四輪電(dian)(dian)(dian)(dian)動(dong)(dong)車，電(dian)(dian)(dian)(dian)動(dong)(dong)觀光車電(dian)(dian)(dian)(dian)動(dong)(dong)巡邏車都是(shi)18v或(huo)者(zhe)72v都是(shi)有(you)一定規格的(de)(de)(de)。但是(shi)電(dian)(dian)(dian)(dian)動(dong)(dong)車電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)容(rong)量單(dan)位不一定相同。所以(yi)建議大(da)(da)(da)家最好(hao)(hao)是(shi)使用(yong)配(pei)套的(de)(de)(de)電(dian)(dian)(dian)(dian)動(dong)(dong)車充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)。當然了，我們知道電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)被充(chong)(chong)(chong)壞跟充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)電(dian)(dian)(dian)(dian)壓有(you)關而不是(shi)跟電(dian)(dian)(dian)(dian)流有(you)關。充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)長時間不轉換或(huo)者(zhe)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)電(dian)(dian)(dian)(dian)壓過高會導(dao)致(zhi)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)失水，電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)鼓(gu)包等情(qing)(qing)(qing)況(kuang)(kuang)發生。電(dian)(dian)(dian)(dian)流對(dui)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)影響是(shi)對(dui)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的(de)(de)(de)快慢而已。但是(shi)會充(chong)(chong)(chong)壞電(dian)(dian)(dian)(dian)動(dong)(dong)車電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)。所以(yi)說電(dian)(dian)(dian)(dian)動(dong)(dong)車充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)不是(shi)不可(ke)(ke)以(yi)通(tong)用(yong)，而是(shi)最好(hao)(hao)不要通(tong)用(yong)。
