電(dian)動(dong)車的提(ti)高(gao)，隨之而(er)來(lai)的充電(dian)問題也(ye)日(ri)益突出，由電(dian)動(dong)車充電(dian)惹起的火災也(ye)日(ri)益嚴(yan)重。
據調查(cha)，2010年，我國電(dian)(dian)(dian)動自行(xing)車(che)(che)保(bao)有量接近1.5億輛。據理(li)解，全國電(dian)(dian)(dian)動車(che)(che)產品抽樣合格率根本堅持在(zai)70%至90%之間。抽查(cha)項目(mu)的檢(jian)測結果顯現，電(dian)(dian)(dian)動車(che)(che)觸及電(dian)(dian)(dian)氣平安(an)指標(biao)不合格項目(mu)主要包(bao)括電(dian)(dian)(dian)氣絕緣性(xing)能、電(dian)(dian)(dian)氣線路敷設、欠(qian)壓過流維護、短路保(bao)險安(an)裝等。
電動車火災(zai)有的(de)發(fa)作在(zai)行駛中，但多數發(fa)作在(zai)充電過程(cheng)(cheng)中。主要緣由是車輛電氣線路(lu)超越(yue)負荷、短路(lu)狀況(kuang)下，由于未裝置電氣平安(an)安(an)裝或電氣平安(an)安(an)裝不(bu)合格，不(bu)能及時有效切(qie)斷電源，大電流引燃(ran)絕(jue)緣或其他易燃(ran)可燃(ran)資料(liao)所(suo)致(zhi)。據統計(ji)電動車火災(zai)事故90%均發(fa)作在(zai)充電過程(cheng)(cheng)中，并且(qie)在(zai)充電4個小時以上(shang)時間段。
由于很多小區沒有裝備電(dian)(dian)(dian)動車(che)充(chong)電(dian)(dian)(dian)站，很多業主不得不本人拉線給電(dian)(dian)(dian)動車(che)充(chong)電(dian)(dian)(dian)站，本人拉線給電(dian)(dian)(dian)動車(che)充(chong)電(dian)(dian)(dian)容(rong)(rong)易充(chong)電(dian)(dian)(dian)過(guo)量，充(chong)電(dian)(dian)(dian)器(qi)內因電(dian)(dian)(dian)子元件過(guo)熱很容(rong)(rong)易招(zhao)致線路短路并(bing)呈(cheng)現火(huo)花，從而引發(fa)火(huo)災。
