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)器(qi)輸出(chu)插(cha)(cha)頭與電(dian)(dian)池(chi)(chi)(chi)盒的(de)充(chong)電(dian)(dian)插(cha)(cha)頭有沒有插(cha)(cha)緊。如(ru)確(que)定(ding)沒有問(wen)題，可檢查一(yi)(yi)下電(dian)(dian)池(chi)(chi)(chi)盒上面(mian)的(de)保險(xian)(xian)絲(si)管是(shi)(shi)否開路或(huo)保險(xian)(xian)絲(si)座有松動接(jie)觸(chu)不(bu)良現象(xiang)。另(ling)外，有的(de)車型要把電(dian)(dian)池(chi)(chi)(chi)鎖打開后才能(neng)充(chong)電(dian)(dian)。如(ru)果以上故障(zhang)均排除(chu)，考慮一(yi)(yi)下充(chong)電(dian)(dian)器(qi)輸出(chu)線是(shi)(shi)否開路，可用(yong)萬(wan)用(yong)表電(dian)(dian)壓擋（200V擋）測量(liang)一(yi)(yi)下充(chong)電(dian)(dian)器(qi)的(de)空載輸出(chu)電(dian)(dian)壓，應為41-44V（配36V電(dian)(dian)池(chi)(chi)(chi)因充(chong)電(dian)(dian)器(qi)不(bu)同有所不(bu)同），如(ru)沒有的(de)話，可能(neng)是(shi)(shi)充(chong)電(dian)(dian)器(qi)輸出(chu)線開路，并將充(chong)電(dian)(dian)器(qi)打開，換(huan)(huan)一(yi)(yi)根輸出(chu)線，即可排除(chu)故障(zhang)。注(zhu)意：在更換(huan)(huan)充(chong)電(dian)(dian)器(qi)輸出(chu)線時，一(yi)(yi)定(ding)要注(zhu)意原機的(de)正負(fu)極不(bu)要接(jie)反(fan)。

二、電源指示燈不亮，充電指示燈也不亮

檢(jian)(jian)(jian)(jian)查充(chong)電(dian)器(qi)(qi)(qi)輸(shu)(shu)入(ru)(ru)電(dian)源插頭與市(shi)電(dian)有(you)沒有(you)連接好，可(ke)將(jiang)充(chong)電(dian)器(qi)(qi)(qi)輸(shu)(shu)入(ru)(ru)插頭插至正常的電(dian)源插座中試一下，如情況依舊，將(jiang)充(chong)電(dian)器(qi)(qi)(qi)外殼(ke)打開(kai)，觀察一下機內保(bao)險絲(si)有(you)沒有(you)斷，如沒有(you)斷，先檢(jian)(jian)(jian)(jian)查一下電(dian)源輸(shu)(shu)入(ru)(ru)線(xian)是(shi)否(fou)良好，在(zai)排除(chu)電(dian)源輸(shu)(shu)入(ru)(ru)線(xian)的故障(zhang)后，應檢(jian)(jian)(jian)(jian)查一下電(dian)路板上(shang)高壓區附(fu)近的元(yuan)(yuan)器(qi)(qi)(qi)件(jian)是(shi)否(fou)有(you)虛焊(han)，保(bao)險絲(si)座是(shi)否(fou)有(you)接觸不良現象，重點(dian)檢(jian)(jian)(jian)(jian)查變(bian)壓器(qi)(qi)(qi)T1、三(san)極管V1、V2等是(shi)否(fou)有(you)虛焊(han)現象。另外，R5或R6開(kai)路，也會引起(qi)上(shang)述(shu)故障(zhang)，如機內保(bao)險絲(si)已斷，則千萬不要(yao)更(geng)(geng)換(huan)大安培(pei)的保(bao)險絲(si)管（充(chong)電(dian)器(qi)(qi)(qi)的保(bao)險絲(si)管一般(ban)為2A），應重點(dian)檢(jian)(jian)(jian)(jian)查D1-D4、V1、V2、R4、R7及D15、D21有(you)無損壞(huai)(huai)，如有(you)損壞(huai)(huai)，可(ke)用同類型的更(geng)(geng)換(huan)。請注意，上(shang)述(shu)元(yuan)(yuan)件(jian)損壞(huai)(huai)時(shi)，可(ke)能會同時(shi)損壞(huai)(huai)一到二個，有(you)時(shi)可(ke)能會同時(shi)損壞(huai)(huai)好幾個，檢(jian)(jian)(jian)(jian)修時(shi)需要(yao)逐一檢(jian)(jian)(jian)(jian)查、更(geng)(geng)換(huan)這些元(yuan)(yuan)件(jian)后才能通(tong)電(dian)。

三、嚴重發熱，甚至有外殼燒化變形現象

這主(zhu)要(yao)(yao)是部分(fen)用戶經常(chang)隨車攜帶(dai)造成(cheng)部分(fen)元器(qi)件松(song)動引起(qi)的故(gu)障(zhang)(zhang)。主(zhu)要(yao)(yao)表現為(wei)：C18松(song)動虛焊時(shi)，會造成(cheng)V1、V2工作狀態不(bu)正(zheng)常(chang)，熱量很(hen)大(da)，嚴(yan)重(zhong)時(shi)充電器(qi)外(wai)殼變形，電路板燒焦，導(dao)致V1、V2損(sun)壞，可將(jiang)C18重(zhong)新焊接好(hao)，檢查(cha)V1、V2、R4、R7。如(ru)仍不(bu)能排除故(gu)障(zhang)(zhang)，則需檢查(cha)D15、D21中是否有(you)一(yi)只開路，另外(wai)，有(you)些廠家的輸出整流管采(cai)用一(yi)只雙二極管，其中一(yi)只開路亦造成(cheng)上述故(gu)障(zhang)(zhang)，有(you)時(shi)該故(gu)障(zhang)(zhang)會造成(cheng)V1、V2中一(yi)只損(sun)壞。需同時(shi)檢查(cha)及更換。

四、發熱量大且伴有異常響聲

故障原因是輸出級消振阻容R31、C17損壞所致。另(ling)外，C12開路或(huo)虛焊也會引起上述(shu)故障。

五、工作時有異常響聲，充不進電

檢查電路板上C8是否有虛(xu)焊或損壞，一般更換C8均能解(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

故障原因是(shi)IC1損壞(huai)，更(geng)換時(shi)務(wu)必小心，不要將(jiang)印(yin)制(zhi)板銅箔損壞(huai)，更(geng)換正常后，需調整R28使充電器輸出電壓在正常工作范圍(wei)內。

七、輸出電壓很高

輸(shu)出電壓很(hen)高（大于(yu)50V），其(qi)故障(zhang)原因是C15短路(lu)或R26開路(lu)，具體(ti)判斷時可測量(liang)IC1集成電路(lu)的(de)“1”腳電壓。

注：更(geng)換R26后，應重新調整R28使充電器(qi)輸出(chu)電壓保(bao)持正常。

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(sun)壞(huai)，如(ru)正常請(qing)更(geng)換IC1即可排除(chu)故(gu)障。

九、輸出電壓正常，充電指示燈無指示或指示不正確

通(tong)常是(shi)由于IC2損壞或LED2損壞，可更換(huan)。

十、輸出部分銅箔燒斷

打開充電(dian)(dian)器(qi)后(hou)發現充電(dian)(dian)器(qi)輸出部分銅箔燒(shao)斷，這通常(chang)是將電(dian)(dian)池正負(fu)極(ji)反接的結果(guo)，由(you)此(ci)而引(yin)起(qi)的故障將會導致(zhi)充電(dian)(dian)器(qi)許多元件損壞(huai)。如果(guo)充電(dian)(dian)器(qi)保險(xian)絲(si)沒有壞(huai)，則通常(chang)更(geng)(geng)換R30、IC1、IC2后(hou)將斷銅箔連上即(ji)可(ke)恢復正常(chang)。如果(guo)充電(dian)(dian)器(qi)的保險(xian)絲(si)已(yi)斷，則故障較嚴重D1-D4、V1-V2、R4、R7等均有可(ke)能損壞(huai)，需(xu)測量后(hou)逐一更(geng)(geng)換。

20、以上(shang)故障適合于市場上(shang)大(da)部分單(dan)管(guan)電(dian)路充電(dian)器常見故障，操作過程中可隨(sui)時咨詢技術人員。

如48V充(chong)(chong)電(dian)(dian)(dian)(dian)器，最高電(dian)(dian)(dian)(dian)壓不(bu)大于(yu)59.6V，大于(yu)此(ci)電(dian)(dian)(dian)(dian)壓，充(chong)(chong)電(dian)(dian)(dian)(dian)可能(neng)不(bu)轉(zhuan)燈，低電(dian)(dian)(dian)(dian)壓不(bu)低于(yu)55V，低于(yu)此(ci)電(dian)(dian)(dian)(dian)壓造成充(chong)(chong)電(dian)(dian)(dian)(dian)不(bu)足，長時(shi)間容(rong)易對(dui)電(dian)(dian)(dian)(dian)池虧電(dian)(dian)(dian)(dian)。 電(dian)(dian)(dian)(dian)流，如48V20A充(chong)(chong)電(dian)(dian)(dian)(dian)器，最大電(dian)(dian)(dian)(dian)流不(bu)大于(yu)3A。大于(yu)3A可能(neng)造成電(dian)(dian)(dian)(dian)池失水較早，最低不(bu)低于(yu)2.1A。低壓此(ci)電(dian)(dian)(dian)(dian)流造成充(chong)(chong)電(dian)(dian)(dian)(dian)不(bu)足。

1、48V新電(dian)池要求充電(dian)器參數，最高電(dian)壓58.5---59.7，不低于(yu)58V，低于(yu)58V造成(cheng)充電(dian)不足，高于(yu)59.7V可能(neng)造成(cheng)充電(dian)不轉燈。轉燈電(dian)流約0.4---0.7A，實際電(dian)壓約55.5V，低于(yu)50V造成(cheng)充電(dian)不足，長時(shi)間充電(dian)電(dian)池虧電(dian)。

2、4820電(dian)(dian)(dian)池(chi)要求充(chong)(chong)電(dian)(dian)(dian)最大電(dian)(dian)(dian)流2.4----3.3A，低于2.2A充(chong)(chong)電(dian)(dian)(dian)慢，充(chong)(chong)電(dian)(dian)(dian)效果差。

3、市場上低于30元的充(chong)電器實際功率小，參數(shu)設(she)計不(bu)精(jing)確，請注意(yi)區(qu)分。

4、充電(dian)器穩(wen)壓電(dian)路失效會造成輸(shu)出電(dian)壓75---130V，充電(dian)電(dian)池(chi)滾燙不轉(zhuan)燈。

5、當新電(dian)池(chi)出現(xian)，續航里(li)程20A電(dian)池(chi)低(di)于30公里(li)，12A電(dian)池(chi)低(di)于25公里(li)請(qing)檢查(cha)充電(dian)器各(ge)項參數，如果無法判斷是，請(qing)更換優(you)質充電(dian)器再次使用，即可解決問題。

6、新電池遇(yu)到(dao)不轉燈(deng)時(shi)，請更換另(ling)外一個優質充電器試機(ji)。

7、正(zheng)常(chang)情況下(xia)。4820新電池(chi)充(chong)(chong)電時(shi)(shi)(shi)間約(yue)(yue)10小(xiao)(xiao)時(shi)(shi)(shi)左右，續航里程(cheng)40---60公里，4812新電池(chi)充(chong)(chong)電時(shi)(shi)(shi)間約(yue)(yue)10小(xiao)(xiao)時(shi)(shi)(shi)內(nei)，里程(cheng)達(da)到25---40公里，如果正(zheng)常(chang)充(chong)(chong)電時(shi)(shi)(shi)間超過以上，請更換優質充(chong)(chong)電器再次(ci)使用。

8、有(you)很(hen)多充(chong)(chong)(chong)電(dian)器內部電(dian)路、輸入輸出(chu)連線(xian)老化，造(zao)成，有(you)時候(hou)能(neng)充(chong)(chong)(chong)、有(you)時候(hou)不能(neng)沖。嚴重影響電(dian)池，或者(zhe)充(chong)(chong)(chong)電(dian)過程中電(dian)路失效(xiao)，造(zao)成充(chong)(chong)(chong)鼓包(bao)，如果出(chu)現(xian)這種情況(kuang)，請直接更換優質(zhi)充(chong)(chong)(chong)電(dian)器再次使(shi)用。

很多朋友都在問電動車充電器可不(bu)可以(yi)(yi)通用這個問題。有(you)回答可以(yi)(yi)的(de)(de)(de)，有(you)對(dui)答不(bu)可以(yi)(yi)的(de)(de)(de)。那(nei)到底聽誰的(de)(de)(de)呢(ni)？買購網建議(yi)：最(zui)好用與電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)車(che)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池配(pei)套(tao)的(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)。因為一般情況(kuang)(kuang)下(xia)(xia)，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)是(shi)(shi)根據電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)車(che)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池大小配(pei)置的(de)(de)(de)，也就(jiu)是(shi)(shi)說電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流大小和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓大小的(de)(de)(de)配(pei)置的(de)(de)(de)。正常情況(kuang)(kuang)下(xia)(xia)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)車(che)，四輪電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)車(che)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)觀光車(che)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)巡邏(luo)車(che)都是(shi)(shi)18v或者72v都是(shi)(shi)有(you)一定規格的(de)(de)(de)。但是(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)車(che)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池的(de)(de)(de)容量單位不(bu)一定相同。所以(yi)(yi)建議(yi)大家最(zui)好是(shi)(shi)使用配(pei)套(tao)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)車(che)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)。當然了，我(wo)們知道電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池被充(chong)(chong)(chong)壞(huai)(huai)跟充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓有(you)關(guan)而不(bu)是(shi)(shi)跟電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流有(you)關(guan)。充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)長時間不(bu)轉(zhuan)換(huan)或者充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓過高會(hui)導致電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池失(shi)水，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池鼓(gu)包等情況(kuang)(kuang)發生。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流對(dui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池的(de)(de)(de)影響是(shi)(shi)對(dui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)快慢而已。但是(shi)(shi)會(hui)充(chong)(chong)(chong)壞(huai)(huai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)車(che)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池。所以(yi)(yi)說電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)車(che)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)不(bu)是(shi)(shi)不(bu)可以(yi)(yi)通用，而是(shi)(shi)最(zui)好不(bu)要通用。
