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)輸(shu)入電(dian)(dian)(dian)源(yuan)插(cha)頭(tou)與市電(dian)(dian)(dian)有沒(mei)有連接好，可(ke)將(jiang)充電(dian)(dian)(dian)器(qi)輸(shu)入插(cha)頭(tou)插(cha)至正常的(de)(de)電(dian)(dian)(dian)源(yuan)插(cha)座(zuo)中試一(yi)(yi)下，如情況依(yi)舊(jiu)，將(jiang)充電(dian)(dian)(dian)器(qi)外殼打(da)開，觀察(cha)一(yi)(yi)下機內保(bao)險(xian)絲(si)有沒(mei)有斷(duan)，如沒(mei)有斷(duan)，先檢(jian)查(cha)一(yi)(yi)下電(dian)(dian)(dian)源(yuan)輸(shu)入線(xian)是否(fou)良好，在排除(chu)電(dian)(dian)(dian)源(yuan)輸(shu)入線(xian)的(de)(de)故障(zhang)后(hou)，應(ying)檢(jian)查(cha)一(yi)(yi)下電(dian)(dian)(dian)路板(ban)上高壓(ya)(ya)區(qu)附近的(de)(de)元器(qi)件(jian)是否(fou)有虛(xu)焊，保(bao)險(xian)絲(si)座(zuo)是否(fou)有接觸不(bu)良現象(xiang)，重(zhong)點(dian)檢(jian)查(cha)變壓(ya)(ya)器(qi)T1、三(san)極管(guan)(guan)V1、V2等(deng)是否(fou)有虛(xu)焊現象(xiang)。另外，R5或R6開路，也(ye)會(hui)(hui)引起上述(shu)故障(zhang)，如機內保(bao)險(xian)絲(si)已斷(duan)，則千萬不(bu)要(yao)更(geng)(geng)換大安(an)培的(de)(de)保(bao)險(xian)絲(si)管(guan)(guan)（充電(dian)(dian)(dian)器(qi)的(de)(de)保(bao)險(xian)絲(si)管(guan)(guan)一(yi)(yi)般為2A），應(ying)重(zhong)點(dian)檢(jian)查(cha)D1-D4、V1、V2、R4、R7及D15、D21有無損(sun)壞，如有損(sun)壞，可(ke)用同(tong)類型的(de)(de)更(geng)(geng)換。請注意，上述(shu)元件(jian)損(sun)壞時，可(ke)能(neng)會(hui)(hui)同(tong)時損(sun)壞一(yi)(yi)到二(er)個，有時可(ke)能(neng)會(hui)(hui)同(tong)時損(sun)壞好幾個，檢(jian)修時需要(yao)逐一(yi)(yi)檢(jian)查(cha)、更(geng)(geng)換這些元件(jian)后(hou)才(cai)能(neng)通電(dian)(dian)(dian)。

三、嚴重發熱，甚至有外殼燒化變形現象

這主(zhu)要(yao)是部分用(yong)戶(hu)經常隨車(che)攜帶造(zao)成(cheng)部分元器(qi)件松(song)動(dong)引起的故障。主(zhu)要(yao)表(biao)現為：C18松(song)動(dong)虛焊時(shi)，會(hui)造(zao)成(cheng)V1、V2工作狀態不正(zheng)常，熱量很大，嚴重時(shi)充(chong)電器(qi)外殼(ke)變(bian)形，電路(lu)板(ban)燒焦，導致V1、V2損(sun)壞，可將(jiang)C18重新焊接好(hao)，檢查(cha)V1、V2、R4、R7。如仍不能排除故障，則(ze)需檢查(cha)D15、D21中(zhong)是否有(you)一只開路(lu)，另外，有(you)些廠家的輸出整流管采用(yong)一只雙二(er)極管，其中(zhong)一只開路(lu)亦造(zao)成(cheng)上述故障，有(you)時(shi)該故障會(hui)造(zao)成(cheng)V1、V2中(zhong)一只損(sun)壞。需同時(shi)檢查(cha)及更換(huan)。

四、發熱量大且伴有異常響聲

故(gu)(gu)障(zhang)原(yuan)因是輸出級消振阻容(rong)R31、C17損壞所(suo)致(zhi)。另外，C12開(kai)路(lu)或虛焊(han)也(ye)會引起上述故(gu)(gu)障(zhang)。

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(han)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

故障原因是IC1損壞，更(geng)換(huan)(huan)時務(wu)必小心，不要(yao)將印制板銅箔損壞，更(geng)換(huan)(huan)正(zheng)常(chang)(chang)后，需調整R28使(shi)充(chong)電器(qi)輸出電壓在(zai)正(zheng)常(chang)(chang)工作范(fan)圍內。

七、輸出電壓很高

輸出電(dian)(dian)壓很高(gao)（大(da)于50V），其故障(zhang)原因(yin)是C15短路(lu)(lu)或R26開路(lu)(lu)，具體(ti)判斷(duan)時(shi)可測量IC1集成電(dian)(dian)路(lu)(lu)的“1”腳電(dian)(dian)壓。

注：更(geng)換(huan)R26后，應(ying)重新調整(zheng)R28使充電器輸出(chu)電壓(ya)保(bao)持正常(chang)。

八、輸出電壓正常，但充電電流很小

檢查R30、R11、R13是否(fou)接觸不(bu)良或損壞，如(ru)正常請(qing)更換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(tong)常(chang)是(shi)由于IC2損(sun)壞或LED2損(sun)壞，可更換。

十、輸出部分銅箔燒斷

打開充(chong)電器(qi)(qi)后發現(xian)充(chong)電器(qi)(qi)輸(shu)出部分(fen)銅(tong)箔(bo)(bo)燒(shao)斷，這通常(chang)是將(jiang)電池正(zheng)負極反接的結果，由此(ci)而引(yin)起的故障將(jiang)會導致充(chong)電器(qi)(qi)許多(duo)元件損壞(huai)。如果充(chong)電器(qi)(qi)保險(xian)絲沒有(you)壞(huai)，則通常(chang)更(geng)換R30、IC1、IC2后將(jiang)斷銅(tong)箔(bo)(bo)連上即可(ke)(ke)恢復正(zheng)常(chang)。如果充(chong)電器(qi)(qi)的保險(xian)絲已斷，則故障較嚴(yan)重D1-D4、V1-V2、R4、R7等(deng)均有(you)可(ke)(ke)能損壞(huai)，需測量后逐(zhu)一更(geng)換。

19、燒3842,3842換新后(hou)試機插電(dian)(dian)聽到一聲喀的一聲響，這(zhe)是(shi)測量大電(dian)(dian)容(rong)2端電(dian)(dian)壓(ya)300V慢慢將，說(shuo)明(ming)3842又擊穿了，先(xian)補(bu)焊(han)線(xian)路(lu)板，檢查變壓(ya)器引腳是(shi)否(fou)(fou)松(song)動或者引線(xian)是(shi)否(fou)(fou)斷(duan)開，輸出部分大二(er)極管是(shi)否(fou)(fou)開路(lu)，線(xian)路(lu)板是(shi)否(fou)(fou)斷(duan)裂。

20、以上故(gu)障適合于市場上大部分單(dan)管電(dian)路充電(dian)器常見故(gu)障，操作過(guo)程中可(ke)隨時咨詢技(ji)術(shu)人員。

如48V充(chong)電(dian)(dian)(dian)(dian)器(qi)，最高電(dian)(dian)(dian)(dian)壓(ya)不(bu)(bu)(bu)大(da)(da)于(yu)(yu)59.6V，大(da)(da)于(yu)(yu)此電(dian)(dian)(dian)(dian)壓(ya)，充(chong)電(dian)(dian)(dian)(dian)可能不(bu)(bu)(bu)轉燈，低(di)(di)(di)電(dian)(dian)(dian)(dian)壓(ya)不(bu)(bu)(bu)低(di)(di)(di)于(yu)(yu)55V，低(di)(di)(di)于(yu)(yu)此電(dian)(dian)(dian)(dian)壓(ya)造(zao)(zao)成充(chong)電(dian)(dian)(dian)(dian)不(bu)(bu)(bu)足，長時(shi)間容易對電(dian)(dian)(dian)(dian)池(chi)虧電(dian)(dian)(dian)(dian)。 電(dian)(dian)(dian)(dian)流(liu)，如48V20A充(chong)電(dian)(dian)(dian)(dian)器(qi)，最大(da)(da)電(dian)(dian)(dian)(dian)流(liu)不(bu)(bu)(bu)大(da)(da)于(yu)(yu)3A。大(da)(da)于(yu)(yu)3A可能造(zao)(zao)成電(dian)(dian)(dian)(dian)池(chi)失水較早，最低(di)(di)(di)不(bu)(bu)(bu)低(di)(di)(di)于(yu)(yu)2.1A。低(di)(di)(di)壓(ya)此電(dian)(dian)(dian)(dian)流(liu)造(zao)(zao)成充(chong)電(dian)(dian)(dian)(dian)不(bu)(bu)(bu)足。

1、48V新電(dian)(dian)池(chi)(chi)要求充(chong)電(dian)(dian)器參數(shu)，最(zui)高(gao)電(dian)(dian)壓(ya)58.5---59.7，不低于58V，低于58V造(zao)(zao)成(cheng)(cheng)(cheng)充(chong)電(dian)(dian)不足，高(gao)于59.7V可能造(zao)(zao)成(cheng)(cheng)(cheng)充(chong)電(dian)(dian)不轉燈。轉燈電(dian)(dian)流約(yue)0.4---0.7A，實際電(dian)(dian)壓(ya)約(yue)55.5V，低于50V造(zao)(zao)成(cheng)(cheng)(cheng)充(chong)電(dian)(dian)不足，長(chang)時間充(chong)電(dian)(dian)電(dian)(dian)池(chi)(chi)虧電(dian)(dian)。

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

3、市場上低于30元的充電器實際功(gong)率(lv)小(xiao)，參數設計不精(jing)確(que)，請注(zhu)意(yi)區分。

4、充電(dian)(dian)器穩(wen)壓(ya)(ya)電(dian)(dian)路失效(xiao)會(hui)造成輸出電(dian)(dian)壓(ya)(ya)75---130V，充電(dian)(dian)電(dian)(dian)池(chi)滾(gun)燙不轉燈。

5、當新電池出現，續航里程20A電池低于30公(gong)里，12A電池低于25公(gong)里請檢(jian)查充電器(qi)各項參數，如果無法判(pan)斷是，請更換優質充電器(qi)再(zai)次使用，即(ji)可(ke)解決(jue)問題。

6、新電池遇(yu)到不(bu)轉燈時(shi)，請(qing)更換另外(wai)一個(ge)優質充電器試機(ji)。

7、正常情況下。4820新電池充(chong)(chong)電時(shi)間約10小時(shi)左右，續航里(li)程40---60公(gong)里(li)，4812新電池充(chong)(chong)電時(shi)間約10小時(shi)內，里(li)程達(da)到25---40公(gong)里(li)，如果正常充(chong)(chong)電時(shi)間超過(guo)以(yi)上(shang)，請更換優(you)質充(chong)(chong)電器再次使(shi)用。

8、有(you)很多充(chong)(chong)電器(qi)(qi)內部(bu)電路(lu)、輸入輸出(chu)連線老化，造(zao)成，有(you)時候(hou)能充(chong)(chong)、有(you)時候(hou)不能沖。嚴(yan)重(zhong)影響電池(chi)，或者充(chong)(chong)電過(guo)程中電路(lu)失效，造(zao)成充(chong)(chong)鼓包，如果出(chu)現這種(zhong)情況(kuang)，請直接更換優質充(chong)(chong)電器(qi)(qi)再次使(shi)用。

很多朋友都在問電動車充電器可(ke)(ke)不(bu)可(ke)(ke)以(yi)(yi)(yi)通(tong)用(yong)這個問題。有(you)回答可(ke)(ke)以(yi)(yi)(yi)的(de)，有(you)對答不(bu)可(ke)(ke)以(yi)(yi)(yi)的(de)。那到底聽誰(shui)的(de)呢？買購網建議：最好(hao)用(yong)與電(dian)(dian)(dian)(dian)動(dong)(dong)車(che)電(dian)(dian)(dian)(dian)池(chi)配(pei)(pei)套的(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)。因為一般情(qing)(qing)況(kuang)下，充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)是(shi)(shi)(shi)(shi)(shi)(shi)根據電(dian)(dian)(dian)(dian)動(dong)(dong)車(che)電(dian)(dian)(dian)(dian)池(chi)大小配(pei)(pei)置(zhi)的(de)，也就是(shi)(shi)(shi)(shi)(shi)(shi)說電(dian)(dian)(dian)(dian)流(liu)大小和電(dian)(dian)(dian)(dian)壓(ya)大小的(de)配(pei)(pei)置(zhi)的(de)。正常情(qing)(qing)況(kuang)下電(dian)(dian)(dian)(dian)動(dong)(dong)車(che)，四(si)輪電(dian)(dian)(dian)(dian)動(dong)(dong)車(che)，電(dian)(dian)(dian)(dian)動(dong)(dong)觀光車(che)電(dian)(dian)(dian)(dian)動(dong)(dong)巡邏(luo)車(che)都(dou)是(shi)(shi)(shi)(shi)(shi)(shi)18v或者(zhe)(zhe)72v都(dou)是(shi)(shi)(shi)(shi)(shi)(shi)有(you)一定(ding)規格的(de)。但是(shi)(shi)(shi)(shi)(shi)(shi)電(dian)(dian)(dian)(dian)動(dong)(dong)車(che)電(dian)(dian)(dian)(dian)池(chi)的(de)容量單位不(bu)一定(ding)相同。所以(yi)(yi)(yi)建議大家最好(hao)是(shi)(shi)(shi)(shi)(shi)(shi)使用(yong)配(pei)(pei)套的(de)電(dian)(dian)(dian)(dian)動(dong)(dong)車(che)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)。當然了，我(wo)們知道(dao)電(dian)(dian)(dian)(dian)池(chi)被充(chong)(chong)(chong)(chong)壞(huai)跟充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)電(dian)(dian)(dian)(dian)壓(ya)有(you)關而不(bu)是(shi)(shi)(shi)(shi)(shi)(shi)跟電(dian)(dian)(dian)(dian)流(liu)有(you)關。充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)長(chang)時(shi)間不(bu)轉換或者(zhe)(zhe)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)電(dian)(dian)(dian)(dian)壓(ya)過高會(hui)導致(zhi)電(dian)(dian)(dian)(dian)池(chi)失水，電(dian)(dian)(dian)(dian)池(chi)鼓包(bao)等情(qing)(qing)況(kuang)發(fa)生。電(dian)(dian)(dian)(dian)流(liu)對電(dian)(dian)(dian)(dian)池(chi)的(de)影響是(shi)(shi)(shi)(shi)(shi)(shi)對電(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的(de)快慢而已。但是(shi)(shi)(shi)(shi)(shi)(shi)會(hui)充(chong)(chong)(chong)(chong)壞(huai)電(dian)(dian)(dian)(dian)動(dong)(dong)車(che)電(dian)(dian)(dian)(dian)池(chi)。所以(yi)(yi)(yi)說電(dian)(dian)(dian)(dian)動(dong)(dong)車(che)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)不(bu)是(shi)(shi)(shi)(shi)(shi)(shi)不(bu)可(ke)(ke)以(yi)(yi)(yi)通(tong)用(yong)，而是(shi)(shi)(shi)(shi)(shi)(shi)最好(hao)不(bu)要通(tong)用(yong)。
