“從(cong)外(wai)因(yin)來說(shuo)，明火(huo)可(ke)(ke)能引(yin)起(qi)爆(bao)炸(zha)；從(cong)內因(yin)來說(shuo)，充電器和電池本身存在質量問題，也可(ke)(ke)能引(yin)起(qi)爆(bao)炸(zha)。”太原(yuan)市交警支隊防(fang)火(huo)處高級(ji)工程師王祈為介紹，像電動(dong)車電池發生爆(bao)炸(zha)的情況很少，但也應該引(yin)起(qi)市民足夠重視(shi)。

　　他介紹，現在許多電動車使用智能充電器，電(dian)(dian)(dian)(dian)(dian)池充(chong)滿電(dian)(dian)(dian)(dian)(dian)后(hou)有(you)自動斷電(dian)(dian)(dian)(dian)(dian)功能。像沒有(you)斷電(dian)(dian)(dian)(dian)(dian)功能的充(chong)電(dian)(dian)(dian)(dian)(dian)器，電(dian)(dian)(dian)(dian)(dian)池充(chong)滿后(hou)繼(ji)續長時(shi)間充(chong)電(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)池可能發生鼓包爆炸(zha)。一旦爆炸(zha)，充(chong)電(dian)(dian)(dian)(dian)(dian)器內的線(xian)路短路就(jiu)會出現(xian)火(huo)花，從而引(yin)發火(huo)災。對(dui)于一般新的蓄(xu)電(dian)(dian)(dian)(dian)(dian)池，前(qian)三次(ci)充(chong)電(dian)(dian)(dian)(dian)(dian)最好在(zai)8―12小時(shi)，以后(hou)掌(zhang)握在(zai)6―8小時(shi)即可。

　　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，充電器過熱引發火患；車主要盡量避免在雨天(tian)、積水(shui)路(lu)段行(xing)駛，以(yi)防電機進(jin)水(shui)，充電時(shi)短路(lu)著火。

    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。
