一、充電時電源指示燈亮，充電指示燈橙色

首先請檢(jian)查(cha)一下充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)輸(shu)出(chu)(chu)插頭與電(dian)(dian)(dian)(dian)(dian)(dian)池盒的充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)插頭有(you)(you)(you)沒有(you)(you)(you)插緊(jin)。如(ru)確定(ding)沒有(you)(you)(you)問(wen)題，可(ke)檢(jian)查(cha)一下電(dian)(dian)(dian)(dian)(dian)(dian)池盒上面的保(bao)險絲管(guan)是(shi)否開(kai)(kai)路(lu)或保(bao)險絲座有(you)(you)(you)松動接(jie)觸不(bu)(bu)良(liang)現象。另外，有(you)(you)(you)的車型要把電(dian)(dian)(dian)(dian)(dian)(dian)池鎖(suo)打開(kai)(kai)后才能充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。如(ru)果以上故障均排除，考慮一下充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)輸(shu)出(chu)(chu)線(xian)是(shi)否開(kai)(kai)路(lu)，可(ke)用(yong)萬用(yong)表電(dian)(dian)(dian)(dian)(dian)(dian)壓擋(dang)(dang)（200V擋(dang)(dang)）測量一下充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)的空載(zai)輸(shu)出(chu)(chu)電(dian)(dian)(dian)(dian)(dian)(dian)壓，應為41-44V（配(pei)36V電(dian)(dian)(dian)(dian)(dian)(dian)池因充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)不(bu)(bu)同有(you)(you)(you)所不(bu)(bu)同），如(ru)沒有(you)(you)(you)的話，可(ke)能是(shi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)輸(shu)出(chu)(chu)線(xian)開(kai)(kai)路(lu)，并將充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)打開(kai)(kai)，換(huan)一根輸(shu)出(chu)(chu)線(xian)，即可(ke)排除故障。注意：在更換(huan)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)輸(shu)出(chu)(chu)線(xian)時，一定(ding)要注意原機的正負極不(bu)(bu)要接(jie)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)(qi)輸(shu)入(ru)(ru)電(dian)源插(cha)頭與(yu)市電(dian)有(you)(you)(you)(you)沒有(you)(you)(you)(you)連(lian)接(jie)(jie)好(hao)(hao)，可(ke)將充電(dian)器(qi)(qi)輸(shu)入(ru)(ru)插(cha)頭插(cha)至正常的電(dian)源插(cha)座中(zhong)試一(yi)下(xia)，如(ru)情(qing)況依(yi)舊，將充電(dian)器(qi)(qi)外(wai)殼打開，觀察(cha)一(yi)下(xia)機(ji)內保(bao)(bao)險(xian)絲(si)有(you)(you)(you)(you)沒有(you)(you)(you)(you)斷，如(ru)沒有(you)(you)(you)(you)斷，先檢(jian)查(cha)一(yi)下(xia)電(dian)源輸(shu)入(ru)(ru)線(xian)是(shi)否良(liang)好(hao)(hao)，在(zai)排除電(dian)源輸(shu)入(ru)(ru)線(xian)的故障(zhang)后，應(ying)檢(jian)查(cha)一(yi)下(xia)電(dian)路板(ban)上高壓(ya)區附(fu)近的元(yuan)(yuan)器(qi)(qi)件是(shi)否有(you)(you)(you)(you)虛(xu)焊，保(bao)(bao)險(xian)絲(si)座是(shi)否有(you)(you)(you)(you)接(jie)(jie)觸不(bu)良(liang)現(xian)象，重點檢(jian)查(cha)變壓(ya)器(qi)(qi)T1、三極管V1、V2等是(shi)否有(you)(you)(you)(you)虛(xu)焊現(xian)象。另(ling)外(wai)，R5或(huo)R6開路，也(ye)會引(yin)起上述故障(zhang)，如(ru)機(ji)內保(bao)(bao)險(xian)絲(si)已斷，則千萬不(bu)要(yao)更(geng)換(huan)大安培的保(bao)(bao)險(xian)絲(si)管（充電(dian)器(qi)(qi)的保(bao)(bao)險(xian)絲(si)管一(yi)般為2A），應(ying)重點檢(jian)查(cha)D1-D4、V1、V2、R4、R7及(ji)D15、D21有(you)(you)(you)(you)無損(sun)(sun)(sun)壞(huai)(huai)，如(ru)有(you)(you)(you)(you)損(sun)(sun)(sun)壞(huai)(huai)，可(ke)用同類(lei)型的更(geng)換(huan)。請注意(yi)，上述元(yuan)(yuan)件損(sun)(sun)(sun)壞(huai)(huai)時(shi)(shi)，可(ke)能會同時(shi)(shi)損(sun)(sun)(sun)壞(huai)(huai)一(yi)到二個，有(you)(you)(you)(you)時(shi)(shi)可(ke)能會同時(shi)(shi)損(sun)(sun)(sun)壞(huai)(huai)好(hao)(hao)幾個，檢(jian)修時(shi)(shi)需要(yao)逐一(yi)檢(jian)查(cha)、更(geng)換(huan)這些元(yuan)(yuan)件后才能通(tong)電(dian)。

三、嚴重發熱，甚至有外殼燒化變形現象

這(zhe)主要是(shi)(shi)部分用戶(hu)經常(chang)隨車攜帶造(zao)(zao)成部分元(yuan)器件松動引起的故障(zhang)(zhang)。主要表現為：C18松動虛(xu)焊(han)時，會造(zao)(zao)成V1、V2工作狀態不正常(chang)，熱量很大，嚴重時充電器外(wai)殼變(bian)形，電路(lu)(lu)板燒焦，導致(zhi)V1、V2損壞(huai)，可將C18重新焊(han)接好，檢查(cha)(cha)V1、V2、R4、R7。如仍不能(neng)排除故障(zhang)(zhang)，則需檢查(cha)(cha)D15、D21中(zhong)是(shi)(shi)否(fou)有一只(zhi)開(kai)(kai)路(lu)(lu)，另外(wai)，有些廠家的輸出整流管采(cai)用一只(zhi)雙二極管，其中(zhong)一只(zhi)開(kai)(kai)路(lu)(lu)亦(yi)造(zao)(zao)成上述故障(zhang)(zhang)，有時該故障(zhang)(zhang)會造(zao)(zao)成V1、V2中(zhong)一只(zhi)損壞(huai)。需同時檢查(cha)(cha)及更換。

四、發熱量大且伴有異常響聲

故(gu)障(zhang)原因是輸出級消(xiao)振(zhen)阻容R31、C17損壞所致。另外，C12開路或虛焊也會引起(qi)上述故(gu)障(zhang)。

五、工作時有異常響聲，充不進電

檢(jian)查電路板上C8是否有虛焊或損壞，一(yi)般更換(huan)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，更(geng)換時務必小(xiao)心(xin)，不要將印制板(ban)銅(tong)箔損壞，更(geng)換正(zheng)常后，需調整(zheng)R28使充電(dian)器輸出電(dian)壓在正(zheng)常工作(zuo)范(fan)圍內(nei)。

七、輸出電壓很高

輸(shu)出電(dian)壓(ya)很高（大于50V），其(qi)故(gu)障原因是(shi)C15短路(lu)或R26開路(lu)，具體判(pan)斷時可測量IC1集(ji)成電(dian)路(lu)的(de)“1”腳電(dian)壓(ya)。

注：更換R26后，應(ying)重新調整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(cha)R30、R11、R13是否接觸不良或損壞，如正常請(qing)更(geng)換IC1即(ji)可(ke)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(sun)壞(huai)或(huo)LED2損(sun)壞(huai)，可更換。

十、輸出部分銅箔燒斷

打開充(chong)電器(qi)后(hou)發現(xian)充(chong)電器(qi)輸出(chu)部分銅箔燒斷，這通常(chang)是將(jiang)電池(chi)正(zheng)負極反接的(de)結(jie)果(guo)，由此而引起的(de)故障(zhang)將(jiang)會(hui)導致充(chong)電器(qi)許(xu)多元件損(sun)壞。如果(guo)充(chong)電器(qi)保險(xian)絲沒有(you)壞，則通常(chang)更(geng)(geng)換R30、IC1、IC2后(hou)將(jiang)斷銅箔連上即可恢復正(zheng)常(chang)。如果(guo)充(chong)電器(qi)的(de)保險(xian)絲已(yi)斷，則故障(zhang)較嚴重D1-D4、V1-V2、R4、R7等均有(you)可能損(sun)壞，需測量(liang)后(hou)逐一更(geng)(geng)換。

1、電(dian)(dian)(dian)源(yuan)不啟動(dong)：插電(dian)(dian)(dian)源(yuan)，大電(dian)(dian)(dian)容(rong)有300V電(dian)(dian)(dian)壓(ya)、拔掉電(dian)(dian)(dian)源(yuan)再次(ci)測量大電(dian)(dian)(dian)容(rong)2端還(huan)是(shi)300V電(dian)(dian)(dian)壓(ya)不下降。給電(dian)(dian)(dian)容(rong)放電(dian)(dian)(dian)后，將(jiang)啟動(dong)電(dian)(dian)(dian)阻換掉即可。啟動(dong)電(dian)(dian)(dian)阻在電(dian)(dian)(dian)源(yuan)輸(shu)入部分，阻值150K，功率2W。

3、閃燈：先(xian)將(jiang)電(dian)路(lu)板(ban)補焊一遍，再次試機，如果還是閃燈，請(qing)檢(jian)查輸出(chu)端取樣電(dian)阻(zu)。0.1歐。3W功率。接在輸出(chu)線的負(fu)極(ji)端，將(jiang)此電(dian)阻(zu)換新即可。

4、輸出(chu)電(dian)壓高(gao)，通電(dian)，電(dian)壓高(gao)于70多V，充電(dian)不轉(zhuan)燈，先將電(dian)路(lu)板補焊(han)一遍，再(zai)(zai)次試機，如果還是電(dian)壓高(gao)，請更換光電(dian)耦合(he)器(qi)、再(zai)(zai)次試機、還是輸出(chu)高(gao)，更換431基準穩壓器(qi)，再(zai)(zai)次試機。

5、吱吱叫，發熱，充電(dian)不(bu)足：通(tong)電(dian)測量大電(dian)容電(dian)壓(ya)，只要(yao)低于300V，一(yi)般電(dian)容失效，更換即可。

6、嚴重發熱，請將風扇換新即可。

7、輸(shu)(shu)出(chu)電壓(ya)不(bu)穩定，先(xian)將(jiang)電路板補焊一遍，后試機，然后將(jiang)輸(shu)(shu)出(chu)端電容(rong)63V470UF電容(rong)換新(xin)試機即可。

9、充電不穩定(ding)，有時(shi)候能充，有時(shi)候不能沖，用測(ce)試儀(yi)檢測(ce)各項數據，然后將(jiang)輸入(ru)輸出(chu)電源線，全部換(huan)新(xin)，補焊(han)線路板試機(ji)。

10、通電燒(shao)保險：先檢測功率管(guan)擊穿沒有，沒有的話將4個整流(liu)二極管(guan)全部(bu)換(huan)新，試(shi)機(ji)。

11、通電(dian)無輸出(chu)，通電(dian)試機(ji)，大電(dian)容2端有(you)300V電(dian)壓，且(qie)慢慢下降，首先檢測輸出(chu)端大二極管擊穿(chuan)沒有(you)，補焊，再次(ci)試機(ji)。

12、通電(dian)(dian)亮2個(ge)紅燈：通電(dian)(dian)試(shi)機(ji)，空載電(dian)(dian)壓(ya)是否正常，然(ran)后將358或324換新試(shi)機(ji)。

13、通電無輸出，能正(zheng)常(chang)啟動，指示燈正(zheng)常(chang)，先將輸出線換新(xin)，對于有繼電器(qi)的(de)充電器(qi)直接(jie)短路繼電器(qi)試(shi)機。

14、通(tong)電(dian)閃燈，請(qing)補(bu)焊變壓器(qi)各引腳(jiao)，然(ran)后試(shi)機，如(ru)果依舊，請(qing)檢(jian)查431、光(guang)電(dian)耦合器(qi)、輸出部分(fen)各二極管是(shi)否(fou)短路，變壓器(qi)磁芯是(shi)否(fou)松動，電(dian)源(yuan)輸入部分(fen)10歐(ou)小電(dian)阻是(shi)否(fou)開路。或(huo)代換3842再次試(shi)機。

15、充電不轉燈，先(xian)用測(ce)試(shi)儀檢(jian)測(ce)各項數(shu)據，一般(ban)充新電池電壓不高(gao)于59.5，充半年左(zuo)右電池不高(gao)于58.8，為正常，高(gao)于此(ci)電壓可(ke)能不轉燈。

16、輸(shu)出電(dian)壓低(di)：補焊線路板。試機，然后將輸(shu)入輸(shu)出大電(dian)容(rong)換新再次試機。

17、輸出(chu)低，發燙(tang)，如果輸出(chu)電(dian)壓(ya)低于(yu)40多V，且功率管(guan)，變(bian)壓(ya)器(qi)發燙(tang)，一般為(wei)變(bian)壓(ya)器(qi)有問題。

19、燒3842,3842換新(xin)后試機插(cha)電聽到一聲喀的一聲響(xiang)，這(zhe)是(shi)測量大(da)電容2端電壓(ya)300V慢慢將，說明3842又擊穿了(le)，先補(bu)焊(han)線路(lu)板，檢查變壓(ya)器引(yin)(yin)腳是(shi)否(fou)松動或者引(yin)(yin)線是(shi)否(fou)斷開，輸出部(bu)分大(da)二極管是(shi)否(fou)開路(lu)，線路(lu)板是(shi)否(fou)斷裂。

20、以(yi)上故(gu)障適合于(yu)市場(chang)上大部分單管電路充電器常見故(gu)障，操作過程中可隨(sui)時咨詢技術人員。

如48V充(chong)(chong)電(dian)(dian)器，最(zui)(zui)高(gao)電(dian)(dian)壓(ya)(ya)不(bu)大于(yu)59.6V，大于(yu)此(ci)電(dian)(dian)壓(ya)(ya)，充(chong)(chong)電(dian)(dian)可(ke)(ke)能不(bu)轉燈，低電(dian)(dian)壓(ya)(ya)不(bu)低于(yu)55V，低于(yu)此(ci)電(dian)(dian)壓(ya)(ya)造成充(chong)(chong)電(dian)(dian)不(bu)足，長時間容易對電(dian)(dian)池虧電(dian)(dian)。 電(dian)(dian)流，如48V20A充(chong)(chong)電(dian)(dian)器，最(zui)(zui)大電(dian)(dian)流不(bu)大于(yu)3A。大于(yu)3A可(ke)(ke)能造成電(dian)(dian)池失水較早，最(zui)(zui)低不(bu)低于(yu)2.1A。低壓(ya)(ya)此(ci)電(dian)(dian)流造成充(chong)(chong)電(dian)(dian)不(bu)足。

1、48V新電(dian)池要求充電(dian)器參數，最高(gao)電(dian)壓(ya)58.5---59.7，不低于58V，低于58V造成(cheng)充電(dian)不足，高(gao)于59.7V可能造成(cheng)充電(dian)不轉燈。轉燈電(dian)流約0.4---0.7A，實(shi)際(ji)電(dian)壓(ya)約55.5V，低于50V造成(cheng)充電(dian)不足，長時間(jian)充電(dian)電(dian)池虧(kui)電(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)效果差(cha)。

3、市場上低于30元的充電器(qi)實(shi)際功率(lv)小，參數(shu)設計(ji)不精確，請注意區分。

4、充電(dian)器穩壓(ya)(ya)電(dian)路(lu)失(shi)效會造成輸出(chu)電(dian)壓(ya)(ya)75---130V，充電(dian)電(dian)池滾燙不(bu)轉燈。

5、當新電(dian)(dian)池出現，續航里(li)程20A電(dian)(dian)池低于30公里(li)，12A電(dian)(dian)池低于25公里(li)請(qing)檢(jian)查充電(dian)(dian)器各項(xiang)參數(shu)，如果無法判斷(duan)是(shi)，請(qing)更(geng)換優質充電(dian)(dian)器再(zai)次使用，即可解(jie)決問題。

6、新電(dian)池(chi)遇(yu)到不轉燈時，請(qing)更換另(ling)外一個優質充電(dian)器(qi)試機。

7、正(zheng)常(chang)情況下。4820新(xin)電池充電時間(jian)約(yue)10小(xiao)時左右，續航(hang)里程(cheng)40---60公里，4812新(xin)電池充電時間(jian)約(yue)10小(xiao)時內，里程(cheng)達(da)到25---40公里，如果正(zheng)常(chang)充電時間(jian)超過以上，請更換優質充電器(qi)再次(ci)使用(yong)。

8、有(you)很(hen)多充(chong)電(dian)器(qi)(qi)內(nei)部電(dian)路、輸入輸出連線老(lao)化，造(zao)成(cheng)，有(you)時候能(neng)充(chong)、有(you)時候不能(neng)沖(chong)。嚴重(zhong)影響電(dian)池，或者充(chong)電(dian)過程中(zhong)電(dian)路失效，造(zao)成(cheng)充(chong)鼓包，如果出現這種情況，請直接更換優質充(chong)電(dian)器(qi)(qi)再(zai)次使用。

很多朋友都在問電動車充電器可不(bu)(bu)可以(yi)通用(yong)(yong)這個問題。有回答可以(yi)的(de)，有對(dui)(dui)答不(bu)(bu)可以(yi)的(de)。那到(dao)底聽誰的(de)呢(ni)？買購網(wang)建(jian)議：最(zui)好(hao)用(yong)(yong)與(yu)電(dian)(dian)(dian)(dian)動(dong)(dong)車(che)電(dian)(dian)(dian)(dian)池(chi)配(pei)套的(de)充(chong)電(dian)(dian)(dian)(dian)器(qi)。因為一般(ban)情況(kuang)下，充(chong)電(dian)(dian)(dian)(dian)器(qi)是(shi)(shi)根據電(dian)(dian)(dian)(dian)動(dong)(dong)車(che)電(dian)(dian)(dian)(dian)池(chi)大小(xiao)配(pei)置的(de)，也(ye)就是(shi)(shi)說(shuo)(shuo)電(dian)(dian)(dian)(dian)流(liu)大小(xiao)和電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)大小(xiao)的(de)配(pei)置的(de)。正常情況(kuang)下電(dian)(dian)(dian)(dian)動(dong)(dong)車(che)，四輪電(dian)(dian)(dian)(dian)動(dong)(dong)車(che)，電(dian)(dian)(dian)(dian)動(dong)(dong)觀(guan)光車(che)電(dian)(dian)(dian)(dian)動(dong)(dong)巡邏車(che)都(dou)是(shi)(shi)18v或者72v都(dou)是(shi)(shi)有一定規格的(de)。但(dan)是(shi)(shi)電(dian)(dian)(dian)(dian)動(dong)(dong)車(che)電(dian)(dian)(dian)(dian)池(chi)的(de)容量(liang)單位不(bu)(bu)一定相(xiang)同。所(suo)(suo)以(yi)建(jian)議大家最(zui)好(hao)是(shi)(shi)使用(yong)(yong)配(pei)套的(de)電(dian)(dian)(dian)(dian)動(dong)(dong)車(che)充(chong)電(dian)(dian)(dian)(dian)器(qi)。當(dang)然(ran)了，我們知(zhi)道(dao)電(dian)(dian)(dian)(dian)池(chi)被(bei)充(chong)壞跟充(chong)電(dian)(dian)(dian)(dian)器(qi)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)有關而(er)不(bu)(bu)是(shi)(shi)跟電(dian)(dian)(dian)(dian)流(liu)有關。充(chong)電(dian)(dian)(dian)(dian)器(qi)長時(shi)間不(bu)(bu)轉(zhuan)換或者充(chong)電(dian)(dian)(dian)(dian)器(qi)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)過(guo)高(gao)會導(dao)致電(dian)(dian)(dian)(dian)池(chi)失水，電(dian)(dian)(dian)(dian)池(chi)鼓包等情況(kuang)發生。電(dian)(dian)(dian)(dian)流(liu)對(dui)(dui)電(dian)(dian)(dian)(dian)池(chi)的(de)影響(xiang)是(shi)(shi)對(dui)(dui)電(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)的(de)快慢而(er)已。但(dan)是(shi)(shi)會充(chong)壞電(dian)(dian)(dian)(dian)動(dong)(dong)車(che)電(dian)(dian)(dian)(dian)池(chi)。所(suo)(suo)以(yi)說(shuo)(shuo)電(dian)(dian)(dian)(dian)動(dong)(dong)車(che)充(chong)電(dian)(dian)(dian)(dian)器(qi)不(bu)(bu)是(shi)(shi)不(bu)(bu)可以(yi)通用(yong)(yong)，而(er)是(shi)(shi)最(zui)好(hao)不(bu)(bu)要通用(yong)(yong)。
