電動車以其出行便捷、低碳環保的優勢迅速進入我們的生活,但它的充電器故障率較高,非常令人頭疼。因充電器價格不算太高且維修復雜,所以有不少車主就直接丟棄,不去維修。其實維修電動車充電器也不是很難,本文將簡單介紹一下電動自行車充電器故障維修方法,以及電動車充電器常見故障如何處理,給大家提供參考。
電動車充電器故障維修方法

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(yi)下(xia)(xia)(xia)充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)輸出(chu)插(cha)頭(tou)與電(dian)(dian)(dian)池(chi)盒(he)的(de)充(chong)(chong)(chong)電(dian)(dian)(dian)插(cha)頭(tou)有(you)沒(mei)(mei)有(you)插(cha)緊(jin)。如(ru)確(que)定沒(mei)(mei)有(you)問題,可(ke)檢(jian)查(cha)一(yi)下(xia)(xia)(xia)電(dian)(dian)(dian)池(chi)盒(he)上面的(de)保險絲管(guan)是否(fou)開(kai)路或(huo)保險絲座有(you)松動接(jie)(jie)觸不(bu)良現象。另外,有(you)的(de)車型要把電(dian)(dian)(dian)池(chi)鎖(suo)打(da)開(kai)后才(cai)能充(chong)(chong)(chong)電(dian)(dian)(dian)。如(ru)果以上故障(zhang)均排除,考慮一(yi)下(xia)(xia)(xia)充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)輸出(chu)線(xian)(xian)是否(fou)開(kai)路,可(ke)用(yong)萬用(yong)表電(dian)(dian)(dian)壓(ya)擋(dang)(200V擋(dang))測量一(yi)下(xia)(xia)(xia)充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)的(de)空(kong)載輸出(chu)電(dian)(dian)(dian)壓(ya),應為(wei)41-44V(配36V電(dian)(dian)(dian)池(chi)因充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)不(bu)同有(you)所不(bu)同),如(ru)沒(mei)(mei)有(you)的(de)話,可(ke)能是充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)輸出(chu)線(xian)(xian)開(kai)路,并將充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)打(da)開(kai),換一(yi)根輸出(chu)線(xian)(xian),即可(ke)排除故障(zhang)。注意:在(zai)更換充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)輸出(chu)線(xian)(xian)時(shi),一(yi)定要注意原機(ji)的(de)正負極不(bu)要接(jie)(jie)反(fan)。

二、電源指示燈不亮,充電指示燈也不亮

檢(jian)查(cha)(cha)充(chong)電(dian)(dian)(dian)(dian)器(qi)輸入(ru)電(dian)(dian)(dian)(dian)源(yuan)插(cha)(cha)頭與市(shi)電(dian)(dian)(dian)(dian)有(you)(you)沒有(you)(you)連接(jie)好,可將(jiang)充(chong)電(dian)(dian)(dian)(dian)器(qi)輸入(ru)插(cha)(cha)頭插(cha)(cha)至(zhi)正(zheng)常(chang)的(de)(de)電(dian)(dian)(dian)(dian)源(yuan)插(cha)(cha)座中試一下(xia)(xia),如情況依舊,將(jiang)充(chong)電(dian)(dian)(dian)(dian)器(qi)外(wai)殼(ke)打開(kai),觀察一下(xia)(xia)機內保(bao)(bao)險(xian)(xian)絲(si)有(you)(you)沒有(you)(you)斷,如沒有(you)(you)斷,先(xian)檢(jian)查(cha)(cha)一下(xia)(xia)電(dian)(dian)(dian)(dian)源(yuan)輸入(ru)線是否良好,在排除電(dian)(dian)(dian)(dian)源(yuan)輸入(ru)線的(de)(de)故障后,應檢(jian)查(cha)(cha)一下(xia)(xia)電(dian)(dian)(dian)(dian)路(lu)板上(shang)高壓區附(fu)近的(de)(de)元(yuan)器(qi)件是否有(you)(you)虛(xu)焊,保(bao)(bao)險(xian)(xian)絲(si)座是否有(you)(you)接(jie)觸不良現象(xiang),重點檢(jian)查(cha)(cha)變壓器(qi)T1、三極管V1、V2等(deng)是否有(you)(you)虛(xu)焊現象(xiang)。另外(wai),R5或R6開(kai)路(lu),也會引起上(shang)述(shu)故障,如機內保(bao)(bao)險(xian)(xian)絲(si)已斷,則千萬不要更(geng)換(huan)大安(an)培(pei)的(de)(de)保(bao)(bao)險(xian)(xian)絲(si)管(充(chong)電(dian)(dian)(dian)(dian)器(qi)的(de)(de)保(bao)(bao)險(xian)(xian)絲(si)管一般(ban)為2A),應重點檢(jian)查(cha)(cha)D1-D4、V1、V2、R4、R7及D15、D21有(you)(you)無損(sun)壞(huai),如有(you)(you)損(sun)壞(huai),可用同類型的(de)(de)更(geng)換(huan)。請注意,上(shang)述(shu)元(yuan)件損(sun)壞(huai)時(shi),可能會同時(shi)損(sun)壞(huai)一到二個(ge),有(you)(you)時(shi)可能會同時(shi)損(sun)壞(huai)好幾個(ge),檢(jian)修(xiu)時(shi)需要逐一檢(jian)查(cha)(cha)、更(geng)換(huan)這(zhe)些元(yuan)件后才(cai)能通電(dian)(dian)(dian)(dian)。

三、嚴重發熱,甚至有外殼燒化變形現象

這主要是部(bu)分用戶經常(chang)(chang)隨車攜帶造成(cheng)部(bu)分元器件松動引(yin)起的(de)故(gu)障(zhang)(zhang)(zhang)。主要表(biao)現為:C18松動虛焊(han)時(shi),會造成(cheng)V1、V2工作狀態(tai)不正常(chang)(chang),熱量很大,嚴(yan)重(zhong)時(shi)充電器外殼變(bian)形,電路(lu)板燒焦,導致(zhi)V1、V2損壞,可(ke)將C18重(zhong)新(xin)焊(han)接好(hao),檢查(cha)V1、V2、R4、R7。如仍(reng)不能排除(chu)故(gu)障(zhang)(zhang)(zhang),則需(xu)檢查(cha)D15、D21中是否有(you)一只(zhi)(zhi)開路(lu),另外,有(you)些廠家(jia)的(de)輸出(chu)整流管采用一只(zhi)(zhi)雙(shuang)二極管,其中一只(zhi)(zhi)開路(lu)亦造成(cheng)上(shang)述故(gu)障(zhang)(zhang)(zhang),有(you)時(shi)該故(gu)障(zhang)(zhang)(zhang)會造成(cheng)V1、V2中一只(zhi)(zhi)損壞。需(xu)同時(shi)檢查(cha)及更(geng)換(huan)。

四、發熱量大且伴有異常響聲

故障原因(yin)是輸出級(ji)消振(zhen)阻容R31、C17損壞所致(zhi)。另外,C12開路或虛(xu)焊也會(hui)引起上述故障。

五、工作時有異常響聲,充不進電

檢查電路板(ban)上C8是否有虛焊或損壞,一般更換C8均(jun)能解決(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(gu)障原因(yin)是(shi)IC1損(sun)壞(huai)(huai),更換時(shi)務必小(xiao)心,不要(yao)將印制板銅(tong)箔損(sun)壞(huai)(huai),更換正(zheng)(zheng)常后(hou),需(xu)調整R28使(shi)充(chong)電器輸出電壓在正(zheng)(zheng)常工作范圍內。

七、輸出電壓很高

輸出(chu)電(dian)壓(ya)很高(大于(yu)50V),其故障原因是C15短(duan)路或R26開路,具體判(pan)斷時可(ke)測量IC1集(ji)成電(dian)路的(de)“1”腳電(dian)壓(ya)。

注:更換(huan)R26后,應重新調整R28使充電(dian)器(qi)輸(shu)出電(dian)壓(ya)保持正常。

八、輸出電壓正常,但充電電流很小

檢查R30、R11、R13是否(fou)接觸不良或損壞(huai),如(ru)正常請更換IC1即可(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(tong)常是(shi)由于IC2損壞或LED2損壞,可更換。

十、輸出部分銅箔燒斷

打開(kai)充(chong)(chong)(chong)電(dian)器后發(fa)現充(chong)(chong)(chong)電(dian)器輸出部分銅箔(bo)燒斷(duan),這通(tong)(tong)常是將電(dian)池正(zheng)負(fu)極反(fan)接的(de)結果(guo),由此而引起的(de)故(gu)障將會導致充(chong)(chong)(chong)電(dian)器許(xu)多元件損(sun)壞(huai)。如(ru)果(guo)充(chong)(chong)(chong)電(dian)器保(bao)(bao)險(xian)絲(si)沒有(you)壞(huai),則通(tong)(tong)常更(geng)換R30、IC1、IC2后將斷(duan)銅箔(bo)連上(shang)即可恢復(fu)正(zheng)常。如(ru)果(guo)充(chong)(chong)(chong)電(dian)器的(de)保(bao)(bao)險(xian)絲(si)已斷(duan),則故(gu)障較(jiao)嚴(yan)重D1-D4、V1-V2、R4、R7等(deng)均有(you)可能損(sun)壞(huai),需測量(liang)后逐一(yi)更(geng)換。

14、通電閃燈,請補焊變壓(ya)(ya)器(qi)各引腳,然后試機(ji),如果依舊(jiu),請檢查431、光電耦合器(qi)、輸出部(bu)分(fen)各二(er)極(ji)管是(shi)否(fou)短路(lu),變壓(ya)(ya)器(qi)磁芯是(shi)否(fou)松動,電源輸入部(bu)分(fen)10歐小電阻是(shi)否(fou)開路(lu)。或代換3842再(zai)次試機(ji)。

15、充(chong)電不(bu)轉燈(deng),先用測(ce)試(shi)儀檢測(ce)各(ge)項(xiang)數據,一般充(chong)新電池電壓不(bu)高(gao)(gao)于59.5,充(chong)半年左右電池不(bu)高(gao)(gao)于58.8,為(wei)正(zheng)常,高(gao)(gao)于此電壓可能不(bu)轉燈(deng)。

2、4820電池要求充電最大電流2.4----3.3A,低于2.2A充電慢,充電效果差。

3、市(shi)場上低于30元的(de)充(chong)電器實(shi)際功率小(xiao),參數設計不精(jing)確,請(qing)注意區分(fen)。

4、充電(dian)(dian)器穩壓電(dian)(dian)路(lu)失效會造(zao)成輸出電(dian)(dian)壓75---130V,充電(dian)(dian)電(dian)(dian)池(chi)滾燙不轉(zhuan)燈(deng)。

5、當新電(dian)(dian)池出(chu)現,續航里程20A電(dian)(dian)池低于(yu)30公里,12A電(dian)(dian)池低于(yu)25公里請檢查充(chong)電(dian)(dian)器各項參數(shu),如果無法判斷(duan)是,請更換優質充(chong)電(dian)(dian)器再次使用(yong),即可解決問(wen)題。

6、新電(dian)池遇到(dao)不轉(zhuan)燈時,請更(geng)換(huan)另外一個優質充電(dian)器試機。

8、有很(hen)多充(chong)(chong)電(dian)(dian)(dian)器(qi)內部電(dian)(dian)(dian)路(lu)、輸(shu)入輸(shu)出連線(xian)老化,造成(cheng),有時候(hou)能充(chong)(chong)、有時候(hou)不(bu)能沖。嚴重影響電(dian)(dian)(dian)池,或(huo)者(zhe)充(chong)(chong)電(dian)(dian)(dian)過程中電(dian)(dian)(dian)路(lu)失(shi)效,造成(cheng)充(chong)(chong)鼓包,如果(guo)出現這種情況,請直(zhi)接(jie)更換(huan)優(you)質充(chong)(chong)電(dian)(dian)(dian)器(qi)再次使用。

電動車充電器最好不要通用

很多朋友都在問電動車充電器可不(bu)(bu)(bu)可以(yi)(yi)(yi)通(tong)用這個問題。有(you)回答(da)(da)可以(yi)(yi)(yi)的(de)(de),有(you)對(dui)答(da)(da)不(bu)(bu)(bu)可以(yi)(yi)(yi)的(de)(de)。那到底聽誰的(de)(de)呢?買(mai)購網建議:最(zui)好用與(yu)電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)車(che)(che)電(dian)(dian)(dian)(dian)池(chi)(chi)配(pei)套(tao)的(de)(de)充(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)。因為(wei)一般情況(kuang)下,充(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)是(shi)(shi)(shi)(shi)根據電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)車(che)(che)電(dian)(dian)(dian)(dian)池(chi)(chi)大小(xiao)配(pei)置的(de)(de),也就是(shi)(shi)(shi)(shi)說電(dian)(dian)(dian)(dian)流大小(xiao)和電(dian)(dian)(dian)(dian)壓(ya)大小(xiao)的(de)(de)配(pei)置的(de)(de)。正(zheng)常情況(kuang)下電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)車(che)(che),四輪(lun)電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)車(che)(che),電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)觀(guan)光車(che)(che)電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)巡邏車(che)(che)都是(shi)(shi)(shi)(shi)18v或者72v都是(shi)(shi)(shi)(shi)有(you)一定規格的(de)(de)。但是(shi)(shi)(shi)(shi)電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)車(che)(che)電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)容量(liang)單位不(bu)(bu)(bu)一定相同。所(suo)以(yi)(yi)(yi)建議大家最(zui)好是(shi)(shi)(shi)(shi)使(shi)用配(pei)套(tao)的(de)(de)電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)車(che)(che)充(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)。當然了(le),我們知道電(dian)(dian)(dian)(dian)池(chi)(chi)被充(chong)壞跟充(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)電(dian)(dian)(dian)(dian)壓(ya)有(you)關(guan)而不(bu)(bu)(bu)是(shi)(shi)(shi)(shi)跟電(dian)(dian)(dian)(dian)流有(you)關(guan)。充(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)長時間不(bu)(bu)(bu)轉(zhuan)換(huan)或者充(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)電(dian)(dian)(dian)(dian)壓(ya)過高(gao)會導致電(dian)(dian)(dian)(dian)池(chi)(chi)失水,電(dian)(dian)(dian)(dian)池(chi)(chi)鼓包等情況(kuang)發生。電(dian)(dian)(dian)(dian)流對(dui)電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)影響是(shi)(shi)(shi)(shi)對(dui)電(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)的(de)(de)快慢而已。但是(shi)(shi)(shi)(shi)會充(chong)壞電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)車(che)(che)電(dian)(dian)(dian)(dian)池(chi)(chi)。所(suo)以(yi)(yi)(yi)說電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)車(che)(che)充(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)不(bu)(bu)(bu)是(shi)(shi)(shi)(shi)不(bu)(bu)(bu)可以(yi)(yi)(yi)通(tong)用,而是(shi)(shi)(shi)(shi)最(zui)好不(bu)(bu)(bu)要通(tong)用。

電源不啟動,插電大電容2端有300V電壓,拔掉電源,大電容電壓慢慢下降,需要將3842換成新的,請問3842是那個元件?

我是72 伏的充電器,充電時燈不亮怎么維修

是只有指示燈不亮,但是正常充電嗎?指示燈僅起到指示作用,如果單單是指示燈壞是沒什么影響的。但指示燈不亮有可能是充電電路故障引起,這種情況就有影響了。一般指示燈不亮但風扇轉的情況正常(充電時轉,充滿電停),就沒有什么影響。
