“從(cong)外因來說，明火可能(neng)引(yin)(yin)起(qi)(qi)爆炸；從(cong)內因來說，充電(dian)器和電(dian)池(chi)本(ben)身(shen)存在質量問(wen)題(ti)，也可能(neng)引(yin)(yin)起(qi)(qi)爆炸。”太原市(shi)交(jiao)警支隊防火處高級工(gong)程師王祈為介(jie)紹，像電(dian)動車電(dian)池(chi)發生爆炸的情況很少，但也應該引(yin)(yin)起(qi)(qi)市(shi)民(min)足夠重(zhong)視。

　　他介紹，現在許多電動車使用智能充電器，電(dian)(dian)(dian)(dian)池充(chong)(chong)滿電(dian)(dian)(dian)(dian)后有自動斷(duan)電(dian)(dian)(dian)(dian)功(gong)能(neng)。像沒有斷(duan)電(dian)(dian)(dian)(dian)功(gong)能(neng)的充(chong)(chong)電(dian)(dian)(dian)(dian)器，電(dian)(dian)(dian)(dian)池充(chong)(chong)滿后繼(ji)續長(chang)時(shi)間充(chong)(chong)電(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)池可(ke)能(neng)發(fa)生鼓(gu)包爆(bao)炸。一旦爆(bao)炸，充(chong)(chong)電(dian)(dian)(dian)(dian)器內的線路短(duan)路就會出現火花，從而引發(fa)火災。對(dui)于一般(ban)新的蓄電(dian)(dian)(dian)(dian)池，前三次充(chong)(chong)電(dian)(dian)(dian)(dian)最好在8―12小(xiao)時(shi)，以后掌握(wo)在6―8小(xiao)時(shi)即可(ke)。

　　另外，電動車充電器盡量不要放在車上，因為有時候路面顛簸容易導致充電器內部發生短路，再充電時容易引起自燃；充電時應將充電器放置在比較容易散熱的地方，以防止充電時間過長，充電器過(guo)熱引發(fa)火患；車主要盡量(liang)避免(mian)在雨天、積水路段行駛(shi)，以防電機(ji)進水，充(chong)電時短路著(zhu)火。

    一旦電動車發生自燃，車主千萬不要去拿電池，因為電池在燃燒過程中有可能爆炸。應該用衣服、雨衣等用力拍打起火處。如果火災難以控制，不可莽撞行事，要及時撥打119報警電話，等消防部門處置。
