首先(xian)請檢查(cha)一(yi)(yi)(yi)下(xia)充(chong)(chong)(chong)電(dian)(dian)器(qi)輸(shu)出插(cha)頭與電(dian)(dian)池(chi)盒(he)的(de)(de)充(chong)(chong)(chong)電(dian)(dian)插(cha)頭有沒有插(cha)緊。如(ru)確定(ding)沒有問題，可檢查(cha)一(yi)(yi)(yi)下(xia)電(dian)(dian)池(chi)盒(he)上面的(de)(de)保險絲管是(shi)否開(kai)路或保險絲座有松動接觸不(bu)良現(xian)象(xiang)。另(ling)外，有的(de)(de)車(che)型要(yao)把電(dian)(dian)池(chi)鎖打開(kai)后才(cai)能(neng)充(chong)(chong)(chong)電(dian)(dian)。如(ru)果(guo)以上故障均排(pai)(pai)除，考慮一(yi)(yi)(yi)下(xia)充(chong)(chong)(chong)電(dian)(dian)器(qi)輸(shu)出線(xian)是(shi)否開(kai)路，可用萬(wan)用表電(dian)(dian)壓擋(dang)（200V擋(dang)）測量一(yi)(yi)(yi)下(xia)充(chong)(chong)(chong)電(dian)(dian)器(qi)的(de)(de)空載輸(shu)出電(dian)(dian)壓，應(ying)為(wei)41-44V（配(pei)36V電(dian)(dian)池(chi)因充(chong)(chong)(chong)電(dian)(dian)器(qi)不(bu)同有所不(bu)同），如(ru)沒有的(de)(de)話，可能(neng)是(shi)充(chong)(chong)(chong)電(dian)(dian)器(qi)輸(shu)出線(xian)開(kai)路，并將充(chong)(chong)(chong)電(dian)(dian)器(qi)打開(kai)，換一(yi)(yi)(yi)根輸(shu)出線(xian)，即可排(pai)(pai)除故障。注(zhu)意：在更換充(chong)(chong)(chong)電(dian)(dian)器(qi)輸(shu)出線(xian)時，一(yi)(yi)(yi)定(ding)要(yao)注(zhu)意原(yuan)機(ji)的(de)(de)正負(fu)極不(bu)要(yao)接反(fan)。

二、電源指示燈不亮，充電指示燈也不亮

檢(jian)(jian)查(cha)充(chong)(chong)(chong)(chong)電(dian)器(qi)輸(shu)(shu)入(ru)電(dian)源插(cha)(cha)頭(tou)與市電(dian)有(you)沒有(you)連接(jie)好，可將充(chong)(chong)(chong)(chong)電(dian)器(qi)輸(shu)(shu)入(ru)插(cha)(cha)頭(tou)插(cha)(cha)至正常的電(dian)源插(cha)(cha)座中試一(yi)下，如情(qing)況依舊，將充(chong)(chong)(chong)(chong)電(dian)器(qi)外(wai)殼(ke)打開(kai)，觀察(cha)一(yi)下機內(nei)保(bao)險絲(si)(si)有(you)沒有(you)斷，如沒有(you)斷，先檢(jian)(jian)查(cha)一(yi)下電(dian)源輸(shu)(shu)入(ru)線是否(fou)良好，在排除電(dian)源輸(shu)(shu)入(ru)線的故障(zhang)(zhang)后(hou)，應(ying)檢(jian)(jian)查(cha)一(yi)下電(dian)路(lu)板上高壓區附近(jin)的元器(qi)件(jian)是否(fou)有(you)虛焊，保(bao)險絲(si)(si)座是否(fou)有(you)接(jie)觸(chu)不良現象(xiang)，重點檢(jian)(jian)查(cha)變壓器(qi)T1、三極管(guan)V1、V2等是否(fou)有(you)虛焊現象(xiang)。另(ling)外(wai)，R5或R6開(kai)路(lu)，也會引起上述故障(zhang)(zhang)，如機內(nei)保(bao)險絲(si)(si)已斷，則千(qian)萬不要更換(huan)大安(an)培的保(bao)險絲(si)(si)管(guan)（充(chong)(chong)(chong)(chong)電(dian)器(qi)的保(bao)險絲(si)(si)管(guan)一(yi)般(ban)為2A），應(ying)重點檢(jian)(jian)查(cha)D1-D4、V1、V2、R4、R7及D15、D21有(you)無損(sun)壞(huai)，如有(you)損(sun)壞(huai)，可用同(tong)類型的更換(huan)。請注意，上述元件(jian)損(sun)壞(huai)時，可能會同(tong)時損(sun)壞(huai)一(yi)到(dao)二個，有(you)時可能會同(tong)時損(sun)壞(huai)好幾個，檢(jian)(jian)修(xiu)時需要逐一(yi)檢(jian)(jian)查(cha)、更換(huan)這些元件(jian)后(hou)才能通電(dian)。

三、嚴重發熱，甚至有外殼燒化變形現象

這主(zhu)要是(shi)部分用戶經(jing)常隨車攜(xie)帶(dai)造(zao)成(cheng)(cheng)部分元器件(jian)松動引起的(de)故障(zhang)。主(zhu)要表現為：C18松動虛(xu)焊時(shi)(shi)，會造(zao)成(cheng)(cheng)V1、V2工作狀態(tai)不正常，熱量很(hen)大，嚴(yan)重(zhong)時(shi)(shi)充電器外殼變(bian)形，電路(lu)板燒焦，導致V1、V2損壞，可將C18重(zhong)新焊接好，檢查(cha)(cha)V1、V2、R4、R7。如仍不能排除故障(zhang)，則(ze)需(xu)檢查(cha)(cha)D15、D21中(zhong)是(shi)否(fou)有(you)一只(zhi)開(kai)路(lu)，另外，有(you)些(xie)廠(chang)家的(de)輸(shu)出整流管采用一只(zhi)雙(shuang)二極管，其(qi)中(zhong)一只(zhi)開(kai)路(lu)亦造(zao)成(cheng)(cheng)上述(shu)故障(zhang)，有(you)時(shi)(shi)該故障(zhang)會造(zao)成(cheng)(cheng)V1、V2中(zhong)一只(zhi)損壞。需(xu)同時(shi)(shi)檢查(cha)(cha)及更換。

四、發熱量大且伴有異常響聲

故障原因是輸(shu)出(chu)級消振(zhen)阻容R31、C17損壞所致。另外，C12開(kai)路或虛焊也會引起(qi)上(shang)述(shu)故障。

五、工作時有異常響聲，充不進電

檢查電路板上C8是否有虛焊或損壞(huai)，一(yi)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(huai)，更(geng)換時務必小心(xin)，不要將印制板(ban)銅箔損壞(huai)，更(geng)換正常后，需調整R28使充電器(qi)輸(shu)出(chu)電壓在(zai)正常工作范(fan)圍內(nei)。

七、輸出電壓很高

輸出電壓很高（大于50V），其(qi)故障原(yuan)因是C15短路或R26開路，具體判斷時可測量IC1集成電路的“1”腳電壓。

注：更換R26后，應重(zhong)新調(diao)整R28使充電器輸出電壓保持(chi)正常。

八、輸出電壓正常，但充電電流很小

檢查(cha)R30、R11、R13是(shi)否接觸不良或損(sun)壞，如正常請更換(huan)IC1即可排(pai)除故(gu)障。

九、輸出電壓正常，充電指示燈無指示或指示不正確

通常是由于IC2損壞(huai)或(huo)LED2損壞(huai)，可更換。

十、輸出部分銅箔燒斷

打開充(chong)(chong)(chong)電器(qi)(qi)(qi)后(hou)發現(xian)充(chong)(chong)(chong)電器(qi)(qi)(qi)輸出部分銅箔燒斷(duan)，這通(tong)常(chang)是將(jiang)電池正負(fu)極(ji)反接的(de)(de)結果(guo)(guo)，由此而引起(qi)的(de)(de)故(gu)障(zhang)將(jiang)會導致充(chong)(chong)(chong)電器(qi)(qi)(qi)許多元件損壞(huai)。如果(guo)(guo)充(chong)(chong)(chong)電器(qi)(qi)(qi)保險絲(si)沒有(you)壞(huai)，則通(tong)常(chang)更換(huan)R30、IC1、IC2后(hou)將(jiang)斷(duan)銅箔連上(shang)即(ji)可恢復正常(chang)。如果(guo)(guo)充(chong)(chong)(chong)電器(qi)(qi)(qi)的(de)(de)保險絲(si)已斷(duan)，則故(gu)障(zhang)較嚴重D1-D4、V1-V2、R4、R7等均有(you)可能損壞(huai)，需測量后(hou)逐一更換(huan)。

20、以上故障(zhang)適(shi)合于(yu)市(shi)場(chang)上大部分單管電(dian)路充電(dian)器常(chang)見故障(zhang)，操(cao)作過程中可隨時咨詢技術(shu)人員。

如48V充電(dian)器，最(zui)高電(dian)壓(ya)(ya)不(bu)(bu)大(da)于(yu)(yu)59.6V，大(da)于(yu)(yu)此(ci)電(dian)壓(ya)(ya)，充電(dian)可能不(bu)(bu)轉燈，低電(dian)壓(ya)(ya)不(bu)(bu)低于(yu)(yu)55V，低于(yu)(yu)此(ci)電(dian)壓(ya)(ya)造成(cheng)充電(dian)不(bu)(bu)足(zu)，長時間容易對(dui)電(dian)池(chi)虧電(dian)。 電(dian)流，如48V20A充電(dian)器，最(zui)大(da)電(dian)流不(bu)(bu)大(da)于(yu)(yu)3A。大(da)于(yu)(yu)3A可能造成(cheng)電(dian)池(chi)失(shi)水較早，最(zui)低不(bu)(bu)低于(yu)(yu)2.1A。低壓(ya)(ya)此(ci)電(dian)流造成(cheng)充電(dian)不(bu)(bu)足(zu)。

1、48V新電(dian)(dian)池要求充(chong)(chong)電(dian)(dian)器參數，最高電(dian)(dian)壓58.5---59.7，不(bu)低于58V，低于58V造成(cheng)充(chong)(chong)電(dian)(dian)不(bu)足，高于59.7V可能(neng)造成(cheng)充(chong)(chong)電(dian)(dian)不(bu)轉燈。轉燈電(dian)(dian)流(liu)約0.4---0.7A，實際電(dian)(dian)壓約55.5V，低于50V造成(cheng)充(chong)(chong)電(dian)(dian)不(bu)足，長(chang)時間充(chong)(chong)電(dian)(dian)電(dian)(dian)池虧電(dian)(dian)。

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

3、市場上低于(yu)30元的(de)充電器(qi)實際功(gong)率小(xiao)，參數(shu)設計不精確(que)，請注意區分。

4、充(chong)電(dian)器穩(wen)壓電(dian)路失效(xiao)會造成輸出電(dian)壓75---130V，充(chong)電(dian)電(dian)池滾燙(tang)不轉(zhuan)燈。

5、當(dang)新(xin)電池(chi)出現，續航里(li)程20A電池(chi)低于30公(gong)里(li)，12A電池(chi)低于25公(gong)里(li)請檢查(cha)充(chong)(chong)電器(qi)各項參數(shu)，如果無法判斷是，請更換優質充(chong)(chong)電器(qi)再次使(shi)用，即(ji)可(ke)解決問(wen)題。

6、新電池遇到不轉燈時(shi)，請更換另外一個優質充電器試機(ji)。

7、正(zheng)常情況下(xia)。4820新電(dian)池充(chong)電(dian)時(shi)間(jian)(jian)約10小時(shi)左右(you)，續航里(li)(li)程40---60公里(li)(li)，4812新電(dian)池充(chong)電(dian)時(shi)間(jian)(jian)約10小時(shi)內(nei)，里(li)(li)程達到25---40公里(li)(li)，如(ru)果正(zheng)常充(chong)電(dian)時(shi)間(jian)(jian)超過以(yi)上，請更換優質充(chong)電(dian)器再次使(shi)用(yong)。

8、有很多(duo)充電(dian)器(qi)內部電(dian)路、輸入輸出連線老化，造(zao)(zao)成，有時候能充、有時候不能沖。嚴重影響電(dian)池，或者(zhe)充電(dian)過程中(zhong)電(dian)路失(shi)效(xiao)，造(zao)(zao)成充鼓包，如(ru)果(guo)出現這種情(qing)況，請直接更換(huan)優質充電(dian)器(qi)再次使用。

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)通用(yong)這個問題。有(you)回答可(ke)(ke)以(yi)(yi)(yi)的(de)(de)(de)(de)，有(you)對答不(bu)可(ke)(ke)以(yi)(yi)(yi)的(de)(de)(de)(de)。那到底聽誰的(de)(de)(de)(de)呢？買(mai)購(gou)網建議(yi)：最好(hao)(hao)用(yong)與電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)車(che)(che)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)配(pei)套的(de)(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器。因(yin)為一(yi)般情況(kuang)下，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器是(shi)(shi)(shi)根(gen)據電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)車(che)(che)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)大小配(pei)置的(de)(de)(de)(de)，也就是(shi)(shi)(shi)說電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流大小和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓大小的(de)(de)(de)(de)配(pei)置的(de)(de)(de)(de)。正常情況(kuang)下電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)車(che)(che)，四輪電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)車(che)(che)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)觀光車(che)(che)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)巡邏車(che)(che)都(dou)是(shi)(shi)(shi)18v或者(zhe)(zhe)72v都(dou)是(shi)(shi)(shi)有(you)一(yi)定規格的(de)(de)(de)(de)。但是(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)車(che)(che)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)(de)容量單位不(bu)一(yi)定相同(tong)。所以(yi)(yi)(yi)建議(yi)大家最好(hao)(hao)是(shi)(shi)(shi)使用(yong)配(pei)套的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)車(che)(che)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器。當然了，我(wo)們知道(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)被充(chong)(chong)(chong)壞跟(gen)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓有(you)關而不(bu)是(shi)(shi)(shi)跟(gen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流有(you)關。充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器長時間不(bu)轉換或者(zhe)(zhe)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓過高會導致電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)失水(shui)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)鼓包等情況(kuang)發(fa)生(sheng)。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流對電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)(de)影(ying)響是(shi)(shi)(shi)對電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)快慢而已。但是(shi)(shi)(shi)會充(chong)(chong)(chong)壞電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)車(che)(che)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。所以(yi)(yi)(yi)說電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)車(che)(che)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器不(bu)是(shi)(shi)(shi)不(bu)可(ke)(ke)以(yi)(yi)(yi)通用(yong)，而是(shi)(shi)(shi)最好(hao)(hao)不(bu)要通用(yong)。
