驚嘆號故障

1、故障原因

一般(ban)這個故障在排除硬件(jian)(jian)問題(ti)以后，大(da)多(duo)是軟件(jian)(jian)和系統標定的問題(ti)。大(da)致原因是系統檢(jian)測(ce)到(dao)電池溫度超(chao)過預設(she)的安全值，或者(zhe)系統檢(jian)測(ce)到(dao)偶(ou)發故障信號(hao)，自作(zuo)主(zhu)張的限制了車輛(liang)的部分功能。

2、應對方案

和解決電(dian)腦死(si)機(ji)，手(shou)機(ji)卡頓的方法(fa)一(yi)(yi)樣，重啟就能(neng)解決大部分問題。純電(dian)動(dong)汽車(che)其實也可以看做一(yi)(yi)個大個頭的電(dian)子產品，所(suo)有電(dian)子系統和主機(ji)的供電(dian)都由(you)發動(dong)機(ji)艙內的小電(dian)瓶負(fu)責。

此時只要用扳手擰下小電瓶的負(fu)極接(jie)線并(bing)保持斷(duan)開5分鐘左(zuo)右，讓車(che)輛車(che)載系統處于徹底(di)斷(duan)電狀態，之后再(zai)將小電瓶負(fu)極線擰緊恢(hui)復。

此時車輛的系統經過斷電處理后，可(ke)視為“重(zhong)啟(qi)”，所有(you)標定和檢(jian)測都恢復初始值，此時再啟(qi)動車輛，幾(ji)乎都可(ke)以順利成功。

動力電池絕緣故障

可能原因：電動汽車電池箱或插件進水，電芯漏液，環境濕度大，絕(jue)緣(yuan)誤報，整車其他高壓部件(控制器、壓縮機等(deng))絕(jue)緣(yuan)不過。

處理方法：正極對地，如果有電壓或絕緣阻值小于規定值，則判處負極電路漏電；負極對地，如(ru)果有(you)電(dian)(dian)(dian)壓(ya)(ya)或絕緣阻(zu)值小于規(gui)定值，則判處(chu)正極電(dian)(dian)(dian)路(lu)漏(lou)電(dian)(dian)(dian)。根據(ju)(ju)其漏(lou)電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)(ya)大小除以此時(shi)的單串電(dian)(dian)(dian)壓(ya)(ya)值就可以計算出漏(lou)電(dian)(dian)(dian)點(dian)位，然后根據(ju)(ju)不同情況(kuang)分析處(chu)理。

功率限制燈亮

這是車(che)(che)主常(chang)見的“烏龜燈”亮(liang)了，故障(zhang)現象(xiang)是車(che)(che)輛的輸(shu)出功率受到限制，車(che)(che)輛只能在40公(gong)里/小(xiao)時的限速下行駛。

1、故障原因

出現(xian)這種(zhong)現(xian)象有幾個原因(yin)，其中除去動力電池即將耗盡，車輛進入保(bao)護(hu)狀態這個非故障原因(yin)之外，最重要的就是系(xi)統檢測車輛在電路系(xi)統有故障，或動力電池溫度超過(guo)安全范圍，需要降低(di)功率(lv)以保(bao)證(zheng)車輛相(xiang)關部件的安全。

2、應對方案

如果是(shi)因為動(dong)力電池(chi)虧電出現烏龜燈(deng)，那么(me)只要盡(jin)快找地方(fang)充電就能解決(jue)；如果是(shi)電池(chi)溫度(du)過高，建議找地方(fang)暫時(shi)停車熄火，等電池(chi)恢復安全溫度(du)后再繼續行(xing)駛；如果急著趕路，車主(zhu)又(you)能自行(xing)確認車輛沒有其他故障(zhang)，那么(me)可以臨時(shi)停車，斷掉發動(dong)機艙內(nei)小電瓶的負極，讓(rang)車輛重啟并“沖(chong)掉”之前(qian)的故障(zhang)警告(gao)記錄。

如果在重(zhong)啟(qi)以及長時間冷卻都無法讓烏龜燈熄(xi)滅，而且(qie)確認動力電池電量充沛，那就還是趕緊聯系(xi)修車吧。

動力電池溫度故障

1、電池溫差過大

可能原因(yin)：散(san)熱風扇插頭松動，散(san)熱風扇故障。

故障排除：重新拔插風(feng)扇(shan)(shan)(shan)插頭(tou)線(xian);給風(feng)扇(shan)(shan)(shan)單獨供(gong)電，檢查(cha)風(feng)扇(shan)(shan)(shan)是否正常。

2、電池溫度過高或過低

可能原因：散熱(re)風扇插頭松動，散熱(re)風扇故障，溫度探頭損壞。

故障排除：重新拔(ba)插風扇插頭線;給風扇單獨供電(dian)，檢查(cha)風扇是否正常(chang);檢查(cha)電(dian)池(chi)實際(ji)溫(wen)度是否過高(gao)或過低(di);測量(liang)溫(wen)度探頭內阻。

3、電動機產生大量火花，局部過熱、抖動

可能原因：

電動機(ji)進水造成短路把電動機(ji)燒壞;

電動機超負載(zai)運(yun)行使換向(xiang)器短路燒壞(huai)，現象是換向(xiang)器變黑(hei)。

電動機異響

可能原因：

電動(dong)機和后(hou)橋連接同心度達不到標(biao)準;

電刷和換向器(qi)接合(he)不好，需校正調整;

電動機里(li)面(mian)轉(zhuan)子上的(de)軸承壞，需更換。

電氣設備件不工作

電動汽車(che)主要(yao)電氣(qi)設備有各種燈具(ju)（前組(zu)合(he)燈、測燈、倒車(che)燈、后組(zu)合(he)燈等）、收(shou)音機、頂部風扇、真(zhen)空泵、刮(gua)水器、組(zu)合(he)儀表(biao)、電動助力轉(zhuan)向器、空調(diao)等。現(xian)場調(diao)試過程中，收(shou)音機、真(zhen)空泵、組(zu)合(he)儀表(biao)和刮(gua)水器經常(chang)出現(xian)不(bu)工作故障。?電氣(qi)設備工作不(bu)正常(chang)主要(yao)是指(zhi)工作狀(zhuang)(zhuang)態(tai)與設計狀(zhuang)(zhuang)態(tai)不(bu)一致，如真(zhen)空泵不(bu)停地抽氣(qi)、組(zu)合(he)儀表(biao)顯示不(bu)正常(chang)、收(shou)音機有很大的(de)干擾(rao)等。

電氣設備不工作的故障分析與處理

電(dian)氣設(she)備(bei)工(gong)作需要符合一(yi)定(ding)的條件(jian)，普遍的條件(jian)是需要有(you)電(dian)源供給(gei)、搭(da)鐵。電(dian)氣設(she)備(bei)不工(gong)作多是因(yin)為沒有(you)電(dian)源供給(gei)，首(shou)先使用萬用表確(que)(que)定(ding)有(you)無電(dian)源供給(gei)，確(que)(que)認(ren)線束插接口(kou)有(you)無松動(dong)情況出現，再確(que)(que)認(ren)搭(da)鐵是否正(zheng)常。如果均無上(shang)述情況，則有(you)可能是此(ci)電(dian)氣設(she)備(bei)自身問題，可以換一(yi)個同款設(she)備(bei)接上(shang)嘗試。這類故(gu)障一(yi)般(ban)是線束環節導致(zhi)電(dian)源供給(gei)中斷，可以根據電(dian)氣原理圖往前推確(que)(que)定(ding)故(gu)障點。

電動汽車整車沒電

1、保險絲壞，用(yong)萬(wan)用(yong)表(biao)測量電(dian)池端電(dian)壓如(ru)有電(dian)壓輸(shu)出(chu)則正(zheng)常，如(ru)無(wu)電(dian)壓輸(shu)出(chu)則保險絲壞或電(dian)池接插頭掉或電(dian)池壞。

2、接(jie)線插頭松動(dong)，檢查電源開(kai)關接(jie)插件(jian)。

3、電源(yuan)開關壞，用(yong)萬用(yong)表(biao)測量電源(yuan)開關輸(shu)入、輸(shu)出線兩端電壓(ya)，如有(you)正(zheng)(zheng)常電壓(ya)輸(shu)出則電源(yuan)開關正(zheng)(zheng)

常，如無電壓輸出(chu)。則電源開關壞〔電池有電壓輸出(chu)情況下〕則予以維修或更換。

充電機不充電

1、充電(dian)機(ji)保險絲燒壞，此時充電(dian)機(ji)各指示燈均不亮，須更換(huan)保險絲。

2、電(dian)池組線掉，則把電(dian)池連(lian)接(jie)線接(jie)好。

3、充電機插(cha)頭(tou)和(he)電池插(cha)座接插(cha)不到位，應(ying)重新接插(cha)。

4、充(chong)電(dian)(dian)(dian)機(ji)(ji)壞，此時充(chong)電(dian)(dian)(dian)機(ji)(ji)保險絲正常，用(yong)(yong)萬用(yong)(yong)表測(ce)充(chong)電(dian)(dian)(dian)機(ji)(ji)輸出電(dian)(dian)(dian)壓應為零(ling)。這種情況下，先斷開電(dian)(dian)(dian)源、停止使用(yong)(yong)充(chong)電(dian)(dian)(dian)機(ji)(ji)，過十幾(ji)分種后(hou)重新(xin)使用(yong)(yong)充(chong)電(dian)(dian)(dian)機(ji)(ji)。

電動機不轉

1、保險絲燒(shao)掉，更換。

2、電(dian)(dian)(dian)源(yuan)開關(guan)壞，更換電(dian)(dian)(dian)源(yuan)開關(guan)。判斷(duan)方(fang)法：打開電(dian)(dian)(dian)源(yuan)開關(guan)，用萬用表歐姆(mu)檔測量一下電(dian)(dian)(dian)源(yuan)開關(guan)的(de)輸入端(duan)與輸出端(duan)之間的(de)電(dian)(dian)(dian)阻(zu)，如電(dian)(dian)(dian)阻(zu)值(zhi)為零則正常，如電(dian)(dian)(dian)阻(zu)值(zhi)無窮大，則電(dian)(dian)(dian)源(yuan)開關(guan)壞。

3、加(jia)速器壞(huai)，用萬(wan)用表直流電壓(ya)檔(dang)測(ce)量一下加(jia)速器輸出(chu)端電壓(ya)，如(ru)有電壓(ya)輸出(chu)則(ze)正常，如(ru)無(wu)電壓(ya)輸出(chu)則(ze)不正常，入伍電壓(ya)輸出(chu)則(ze)加(jia)速器壞(huai)，須更換(huan)。

4、控(kong)制器壞(huai)，須更換電控(kong)。用萬用表測量電控(kong)輸(shu)出(chu)(chu)端電壓，有輸(shu)出(chu)(chu)電壓則好，否(fou)則則壞(huai)。

5、電(dian)動機燒壞，更(geng)換電(dian)動機。

6、電動(dong)(dong)機(ji)(ji)各連接線(xian)(xian)線(xian)(xian)頭松(song)動(dong)(dong)，把電動(dong)(dong)機(ji)(ji)各連接線(xian)(xian)頭重(zhong)新檢(jian)查一遍。
