一、充電時電源指示燈亮，充電指示燈橙色

首先(xian)請檢查一(yi)(yi)下充(chong)電(dian)(dian)(dian)器(qi)輸(shu)出插(cha)頭(tou)(tou)與電(dian)(dian)(dian)池(chi)盒(he)的充(chong)電(dian)(dian)(dian)插(cha)頭(tou)(tou)有(you)沒有(you)插(cha)緊(jin)。如確定沒有(you)問題，可(ke)檢查一(yi)(yi)下電(dian)(dian)(dian)池(chi)盒(he)上(shang)(shang)面(mian)的保險(xian)絲管是(shi)(shi)(shi)否(fou)開(kai)路(lu)(lu)或保險(xian)絲座有(you)松動接觸不(bu)(bu)良現(xian)象。另外，有(you)的車型要把電(dian)(dian)(dian)池(chi)鎖打(da)開(kai)后才能充(chong)電(dian)(dian)(dian)。如果以上(shang)(shang)故(gu)(gu)障(zhang)均排除，考慮一(yi)(yi)下充(chong)電(dian)(dian)(dian)器(qi)輸(shu)出線是(shi)(shi)(shi)否(fou)開(kai)路(lu)(lu)，可(ke)用萬用表電(dian)(dian)(dian)壓擋(dang)（200V擋(dang)）測量一(yi)(yi)下充(chong)電(dian)(dian)(dian)器(qi)的空(kong)載輸(shu)出電(dian)(dian)(dian)壓，應為41-44V（配36V電(dian)(dian)(dian)池(chi)因充(chong)電(dian)(dian)(dian)器(qi)不(bu)(bu)同有(you)所不(bu)(bu)同），如沒有(you)的話，可(ke)能是(shi)(shi)(shi)充(chong)電(dian)(dian)(dian)器(qi)輸(shu)出線開(kai)路(lu)(lu)，并(bing)將充(chong)電(dian)(dian)(dian)器(qi)打(da)開(kai)，換一(yi)(yi)根輸(shu)出線，即可(ke)排除故(gu)(gu)障(zhang)。注意(yi)：在更換充(chong)電(dian)(dian)(dian)器(qi)輸(shu)出線時，一(yi)(yi)定要注意(yi)原機的正負極不(bu)(bu)要接反。

二、電源指示燈不亮，充電指示燈也不亮

檢(jian)查(cha)充電(dian)(dian)(dian)器(qi)(qi)輸入(ru)(ru)電(dian)(dian)(dian)源(yuan)插(cha)(cha)頭(tou)與市電(dian)(dian)(dian)有(you)(you)沒有(you)(you)連接好(hao)，可(ke)將充電(dian)(dian)(dian)器(qi)(qi)輸入(ru)(ru)插(cha)(cha)頭(tou)插(cha)(cha)至正常的(de)(de)(de)電(dian)(dian)(dian)源(yuan)插(cha)(cha)座(zuo)中試一(yi)下，如(ru)情(qing)況(kuang)依舊，將充電(dian)(dian)(dian)器(qi)(qi)外殼打開(kai)，觀察一(yi)下機內保(bao)險絲(si)有(you)(you)沒有(you)(you)斷(duan)，如(ru)沒有(you)(you)斷(duan)，先檢(jian)查(cha)一(yi)下電(dian)(dian)(dian)源(yuan)輸入(ru)(ru)線(xian)是(shi)(shi)否良(liang)好(hao)，在排除電(dian)(dian)(dian)源(yuan)輸入(ru)(ru)線(xian)的(de)(de)(de)故障后，應(ying)檢(jian)查(cha)一(yi)下電(dian)(dian)(dian)路板上(shang)高(gao)壓區附(fu)近的(de)(de)(de)元器(qi)(qi)件是(shi)(shi)否有(you)(you)虛(xu)焊，保(bao)險絲(si)座(zuo)是(shi)(shi)否有(you)(you)接觸(chu)不良(liang)現象，重點檢(jian)查(cha)變(bian)壓器(qi)(qi)T1、三極管V1、V2等(deng)是(shi)(shi)否有(you)(you)虛(xu)焊現象。另外，R5或R6開(kai)路，也會(hui)引起上(shang)述故障，如(ru)機內保(bao)險絲(si)已斷(duan)，則千萬不要更(geng)換大安培的(de)(de)(de)保(bao)險絲(si)管（充電(dian)(dian)(dian)器(qi)(qi)的(de)(de)(de)保(bao)險絲(si)管一(yi)般(ban)為(wei)2A），應(ying)重點檢(jian)查(cha)D1-D4、V1、V2、R4、R7及D15、D21有(you)(you)無損(sun)壞(huai)(huai)，如(ru)有(you)(you)損(sun)壞(huai)(huai)，可(ke)用同類型的(de)(de)(de)更(geng)換。請注意，上(shang)述元件損(sun)壞(huai)(huai)時，可(ke)能會(hui)同時損(sun)壞(huai)(huai)一(yi)到(dao)二個，有(you)(you)時可(ke)能會(hui)同時損(sun)壞(huai)(huai)好(hao)幾個，檢(jian)修(xiu)時需要逐一(yi)檢(jian)查(cha)、更(geng)換這些元件后才能通(tong)電(dian)(dian)(dian)。

三、嚴重發熱，甚至有外殼燒化變形現象

這(zhe)主要(yao)是部分用戶經常隨車攜(xie)帶造(zao)成(cheng)部分元器(qi)件松動引(yin)起(qi)的(de)故障。主要(yao)表現為：C18松動虛焊時，會(hui)造(zao)成(cheng)V1、V2工(gong)作狀態(tai)不正常，熱量很(hen)大，嚴(yan)重(zhong)時充(chong)電(dian)器(qi)外(wai)殼變形(xing)，電(dian)路板燒焦，導致(zhi)V1、V2損壞(huai)，可將C18重(zhong)新焊接好(hao)，檢(jian)查V1、V2、R4、R7。如仍不能排(pai)除故障，則需檢(jian)查D15、D21中(zhong)是否有一(yi)(yi)只開(kai)路，另外(wai)，有些廠家的(de)輸(shu)出整流管采(cai)用一(yi)(yi)只雙二極管，其(qi)中(zhong)一(yi)(yi)只開(kai)路亦造(zao)成(cheng)上述故障，有時該(gai)故障會(hui)造(zao)成(cheng)V1、V2中(zhong)一(yi)(yi)只損壞(huai)。需同時檢(jian)查及更換。

四、發熱量大且伴有異常響聲

故障原因是(shi)輸出級(ji)消振阻容(rong)R31、C17損壞所致(zhi)。另外，C12開路(lu)或(huo)虛焊也(ye)會引起上述故障。

五、工作時有異常響聲，充不進電

檢查電路板上C8是(shi)否有虛焊或損壞，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(gu)障原因是IC1損壞(huai)，更換時務(wu)必小心，不要將(jiang)印制板銅(tong)箔損壞(huai)，更換正常(chang)后，需調整R28使充電(dian)器輸出電(dian)壓在正常(chang)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(yuan)因是C15短路(lu)或R26開路(lu)，具體判斷時可測量IC1集成(cheng)電路(lu)的(de)“1”腳電壓(ya)。

注：更換R26后(hou)，應重(zhong)新調整R28使充電(dian)(dian)器輸出(chu)電(dian)(dian)壓(ya)保持(chi)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(huo)損壞，如正常請(qing)更換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損壞或LED2損壞，可(ke)更換。

十、輸出部分銅箔燒斷

打開(kai)充(chong)(chong)電(dian)器后(hou)發現充(chong)(chong)電(dian)器輸(shu)出部分銅(tong)箔燒(shao)斷，這通常(chang)是將(jiang)電(dian)池正負極反接的結(jie)果，由(you)此而(er)引起(qi)的故(gu)障將(jiang)會導致充(chong)(chong)電(dian)器許多(duo)元件損壞(huai)(huai)。如果充(chong)(chong)電(dian)器保(bao)險(xian)(xian)絲(si)沒(mei)有壞(huai)(huai)，則通常(chang)更(geng)換(huan)R30、IC1、IC2后(hou)將(jiang)斷銅(tong)箔連上即可恢復正常(chang)。如果充(chong)(chong)電(dian)器的保(bao)險(xian)(xian)絲(si)已斷，則故(gu)障較嚴重D1-D4、V1-V2、R4、R7等均有可能(neng)損壞(huai)(huai)，需(xu)測量后(hou)逐一更(geng)換(huan)。

1、電(dian)源(yuan)不啟動(dong)：插電(dian)源(yuan)，大電(dian)容(rong)有300V電(dian)壓、拔掉(diao)電(dian)源(yuan)再次測(ce)量大電(dian)容(rong)2端還是300V電(dian)壓不下(xia)降。給電(dian)容(rong)放電(dian)后，將啟動(dong)電(dian)阻(zu)換掉(diao)即可。啟動(dong)電(dian)阻(zu)在(zai)電(dian)源(yuan)輸(shu)入部分，阻(zu)值(zhi)150K，功(gong)率(lv)2W。

3、閃(shan)燈(deng)：先將電路板補焊一遍，再次(ci)試機(ji)，如果還是(shi)閃(shan)燈(deng)，請檢查輸出端取樣電阻。0.1歐。3W功率。接在輸出線的負(fu)極(ji)端，將此(ci)電阻換(huan)新即可。

4、輸出電(dian)壓(ya)(ya)高(gao)，通電(dian)，電(dian)壓(ya)(ya)高(gao)于70多V，充電(dian)不轉燈，先將電(dian)路(lu)板補焊一遍，再次(ci)試機，如果還是(shi)電(dian)壓(ya)(ya)高(gao)，請更換(huan)(huan)光電(dian)耦合器(qi)、再次(ci)試機、還是(shi)輸出高(gao)，更換(huan)(huan)431基準穩壓(ya)(ya)器(qi)，再次(ci)試機。

5、吱吱叫(jiao)，發熱，充電(dian)不足：通電(dian)測量大(da)電(dian)容電(dian)壓(ya)，只(zhi)要低于300V，一般(ban)電(dian)容失效，更換(huan)即可。

6、嚴重發熱(re)，請將風扇換(huan)新即(ji)可(ke)。

7、輸出(chu)(chu)電(dian)壓不穩定，先將(jiang)(jiang)電(dian)路板補(bu)焊一(yi)遍，后試機，然(ran)后將(jiang)(jiang)輸出(chu)(chu)端(duan)電(dian)容(rong)63V470UF電(dian)容(rong)換新試機即可(ke)。

8、充電(dian)不轉燈，用檢(jian)測儀測試(shi)各(ge)項數據(ju)，然(ran)后將358或者324換新試(shi)機。

9、充(chong)電不穩定，有時候(hou)能充(chong)，有時候(hou)不能沖，用測試儀檢測各項(xiang)數據，然后將輸(shu)入輸(shu)出(chu)電源線，全部換新(xin)，補焊線路板試機(ji)。

10、通電燒保(bao)險：先檢測功率管(guan)擊(ji)穿沒(mei)有(you)，沒(mei)有(you)的話(hua)將(jiang)4個(ge)整流二極管(guan)全(quan)部換新，試機。

11、通電無輸出，通電試機，大(da)電容2端有(you)300V電壓(ya)，且慢慢下降，首先(xian)檢測輸出端大(da)二極管擊穿沒有(you)，補焊(han)，再次試機。

12、通電(dian)亮(liang)2個紅燈(deng)：通電(dian)試(shi)機，空載電(dian)壓是否正(zheng)常，然后將358或324換新試(shi)機。

13、通電無輸出，能(neng)正(zheng)常(chang)啟動，指示燈(deng)正(zheng)常(chang)，先(xian)將輸出線(xian)換(huan)新，對于有繼電器的充電器直(zhi)接短路繼電器試機。

14、通電閃(shan)燈，請補焊變壓器各(ge)引腳(jiao)，然后試機，如果(guo)依(yi)舊，請檢(jian)查431、光電耦合器、輸(shu)(shu)出部分各(ge)二極管是(shi)(shi)否短路，變壓器磁芯是(shi)(shi)否松(song)動，電源(yuan)輸(shu)(shu)入部分10歐小電阻(zu)是(shi)(shi)否開路。或代換3842再次(ci)試機。

15、充電不(bu)轉(zhuan)燈(deng)(deng)，先用測(ce)試(shi)儀檢測(ce)各項數據，一般充新電池(chi)電壓不(bu)高(gao)于(yu)59.5，充半年左(zuo)右電池(chi)不(bu)高(gao)于(yu)58.8，為(wei)正常(chang)，高(gao)于(yu)此電壓可能(neng)不(bu)轉(zhuan)燈(deng)(deng)。

16、輸(shu)(shu)出(chu)電壓低：補(bu)焊線路(lu)板。試機，然(ran)后將輸(shu)(shu)入輸(shu)(shu)出(chu)大電容換新再次試機。

17、輸出低，發(fa)燙，如果輸出電壓(ya)低于40多V，且(qie)功率管，變壓(ya)器發(fa)燙，一(yi)般為變壓(ya)器有問題。

18、啟動(dong)困難，有(you)時候(hou)能起到有(you)時候(hou)不能啟動(dong)，補焊(han)線路板，后(hou)試機(ji)，如果依舊請(qing)將(jiang)輸入部分小電(dian)容換新(xin)再(zai)次試機(ji)，50V47UF。

19、燒3842,3842換新(xin)后試機(ji)插(cha)電(dian)聽到一聲喀(ka)的(de)一聲響，這是測量(liang)大電(dian)容2端(duan)電(dian)壓300V慢慢將，說明3842又擊穿(chuan)了，先補(bu)焊線路板，檢查變壓器引(yin)腳是否(fou)松(song)動或者(zhe)引(yin)線是否(fou)斷(duan)開，輸出部分大二極管是否(fou)開路，線路板是否(fou)斷(duan)裂。

20、以上故(gu)障適合于市場上大部分單管電路(lu)充電器常見(jian)故(gu)障，操作過程中(zhong)可隨時咨詢(xun)技(ji)術人員。

如(ru)48V充電(dian)(dian)器，最高電(dian)(dian)壓(ya)(ya)不大(da)于59.6V，大(da)于此電(dian)(dian)壓(ya)(ya)，充電(dian)(dian)可能(neng)不轉燈，低(di)電(dian)(dian)壓(ya)(ya)不低(di)于55V，低(di)于此電(dian)(dian)壓(ya)(ya)造成充電(dian)(dian)不足，長時間容(rong)易對電(dian)(dian)池虧電(dian)(dian)。 電(dian)(dian)流，如(ru)48V20A充電(dian)(dian)器，最大(da)電(dian)(dian)流不大(da)于3A。大(da)于3A可能(neng)造成電(dian)(dian)池失(shi)水較早，最低(di)不低(di)于2.1A。低(di)壓(ya)(ya)此電(dian)(dian)流造成充電(dian)(dian)不足。

1、48V新電(dian)(dian)池(chi)(chi)要(yao)求(qiu)充(chong)電(dian)(dian)器參(can)數，最(zui)高(gao)電(dian)(dian)壓58.5---59.7，不(bu)低(di)于58V，低(di)于58V造(zao)成充(chong)電(dian)(dian)不(bu)足，高(gao)于59.7V可能造(zao)成充(chong)電(dian)(dian)不(bu)轉(zhuan)燈。轉(zhuan)燈電(dian)(dian)流約(yue)0.4---0.7A，實際電(dian)(dian)壓約(yue)55.5V，低(di)于50V造(zao)成充(chong)電(dian)(dian)不(bu)足，長時間充(chong)電(dian)(dian)電(dian)(dian)池(chi)(chi)虧電(dian)(dian)。

2、4820電(dian)池要求充電(dian)最大(da)電(dian)流2.4----3.3A，低于(yu)2.2A充電(dian)慢，充電(dian)效(xiao)果(guo)差。

3、市場上低于30元(yuan)的充電器實際功率小，參數(shu)設計不精確，請注(zhu)意區分。

4、充(chong)電(dian)(dian)器穩壓電(dian)(dian)路(lu)失效會(hui)造成(cheng)輸出(chu)電(dian)(dian)壓75---130V，充(chong)電(dian)(dian)電(dian)(dian)池(chi)滾燙不(bu)轉燈。

5、當新電(dian)(dian)(dian)(dian)池(chi)出現，續航(hang)里程20A電(dian)(dian)(dian)(dian)池(chi)低于(yu)30公里，12A電(dian)(dian)(dian)(dian)池(chi)低于(yu)25公里請(qing)檢查充(chong)電(dian)(dian)(dian)(dian)器各項(xiang)參數，如果無法判(pan)斷是，請(qing)更(geng)換優質(zhi)充(chong)電(dian)(dian)(dian)(dian)器再次(ci)使用(yong)，即可解(jie)決問題。

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

7、正常(chang)情況下。4820新(xin)電(dian)(dian)池充電(dian)(dian)時(shi)間約(yue)10小時(shi)左右，續航里(li)程(cheng)40---60公里(li)，4812新(xin)電(dian)(dian)池充電(dian)(dian)時(shi)間約(yue)10小時(shi)內(nei)，里(li)程(cheng)達到(dao)25---40公里(li)，如果正常(chang)充電(dian)(dian)時(shi)間超過(guo)以上，請更換優質充電(dian)(dian)器再次使用。

8、有很多(duo)充電(dian)(dian)器內部電(dian)(dian)路、輸入輸出連線老化，造成，有時候能(neng)充、有時候不能(neng)沖。嚴重影響電(dian)(dian)池(chi)，或(huo)者充電(dian)(dian)過程(cheng)中電(dian)(dian)路失效，造成充鼓包，如果(guo)出現這種情況，請直(zhi)接(jie)更(geng)換優(you)質(zhi)充電(dian)(dian)器再次使用。

很多朋友都在問電動車充電器可(ke)(ke)不(bu)(bu)(bu)可(ke)(ke)以(yi)通(tong)(tong)用(yong)這個問(wen)題。有回答可(ke)(ke)以(yi)的(de)(de)(de)，有對(dui)答不(bu)(bu)(bu)可(ke)(ke)以(yi)的(de)(de)(de)。那到(dao)底聽誰的(de)(de)(de)呢？買(mai)購(gou)網建(jian)議(yi)：最好(hao)用(yong)與電(dian)(dian)(dian)(dian)(dian)動車(che)(che)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)配套的(de)(de)(de)充電(dian)(dian)(dian)(dian)(dian)器(qi)。因(yin)為(wei)一般情況下，充電(dian)(dian)(dian)(dian)(dian)器(qi)是根據電(dian)(dian)(dian)(dian)(dian)動車(che)(che)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)大(da)小配置(zhi)的(de)(de)(de)，也就(jiu)是說電(dian)(dian)(dian)(dian)(dian)流大(da)小和電(dian)(dian)(dian)(dian)(dian)壓(ya)大(da)小的(de)(de)(de)配置(zhi)的(de)(de)(de)。正常情況下電(dian)(dian)(dian)(dian)(dian)動車(che)(che)，四輪電(dian)(dian)(dian)(dian)(dian)動車(che)(che)，電(dian)(dian)(dian)(dian)(dian)動觀光車(che)(che)電(dian)(dian)(dian)(dian)(dian)動巡邏車(che)(che)都是18v或(huo)者(zhe)72v都是有一定(ding)規格的(de)(de)(de)。但是電(dian)(dian)(dian)(dian)(dian)動車(che)(che)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)容(rong)量單位(wei)不(bu)(bu)(bu)一定(ding)相(xiang)同。所(suo)以(yi)建(jian)議(yi)大(da)家最好(hao)是使(shi)用(yong)配套的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)動車(che)(che)充電(dian)(dian)(dian)(dian)(dian)器(qi)。當然了，我們知(zhi)道(dao)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)被充壞跟充電(dian)(dian)(dian)(dian)(dian)器(qi)電(dian)(dian)(dian)(dian)(dian)壓(ya)有關(guan)而不(bu)(bu)(bu)是跟電(dian)(dian)(dian)(dian)(dian)流有關(guan)。充電(dian)(dian)(dian)(dian)(dian)器(qi)長時間不(bu)(bu)(bu)轉換或(huo)者(zhe)充電(dian)(dian)(dian)(dian)(dian)器(qi)電(dian)(dian)(dian)(dian)(dian)壓(ya)過高會導致電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)失(shi)水，電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)鼓(gu)包等(deng)情況發生。電(dian)(dian)(dian)(dian)(dian)流對(dui)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)影響是對(dui)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)充電(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)快慢而已。但是會充壞電(dian)(dian)(dian)(dian)(dian)動車(che)(che)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)。所(suo)以(yi)說電(dian)(dian)(dian)(dian)(dian)動車(che)(che)充電(dian)(dian)(dian)(dian)(dian)器(qi)不(bu)(bu)(bu)是不(bu)(bu)(bu)可(ke)(ke)以(yi)通(tong)(tong)用(yong)，而是最好(hao)不(bu)(bu)(bu)要(yao)通(tong)(tong)用(yong)。
