一、純電動汽車容易自燃嗎

純電動汽車不(bu)易(yi)自(zi)燃爆炸。雖(sui)然近年(nian)來不(bu)斷有各種新(xin)(xin)聞報道(dao)某品牌新(xin)(xin)能源電動汽車(che)自(zi)燃，但(dan)根據國家監管平臺安全監管數據顯示，近兩年(nian)新(xin)(xin)能源汽車(che)起火事(shi)故(gu)的概率僅為0.000026%，而傳統燃油車(che)的起火事(shi)故(gu)概率為0.0001-0.0002%。

由此可見，新能(neng)源電動(dong)汽車起火的概率還是比較(jiao)小的。目(mu)前，我國(guo)新能(neng)源汽車保有(you)量(liang)已超過1000萬輛，但(dan)無故發生自燃事故的新能(neng)源汽車屈指(zhi)可數(shu)。

當(dang)然，新能(neng)源(yuan)(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動汽(qi)車(che)(che)不(bu)易自(zi)(zi)燃(ran)并(bing)不(bu)代表車(che)(che)輛(liang)不(bu)會(hui)自(zi)(zi)燃(ran)。純電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動汽(qi)車(che)(che)自(zi)(zi)燃(ran)基本源(yuan)(yuan)于動力電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。起火事故的(de)(de)原因中(zhong)，動力電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)自(zi)(zi)燃(ran)占比為31%。快速充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)時，導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)性不(bu)好(hao)的(de)(de)鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)容易產生(sheng)大(da)量(liang)熱量(liang)，溫度急劇(ju)升高(gao)，導(dao)(dao)致熱失(shi)控。汽(qi)車(che)(che)在充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)過程中(zhong)發生(sheng)自(zi)(zi)燃(ran)，也(ye)有(you)可能(neng)是(shi)車(che)(che)主操作不(bu)當(dang)引(yin)發。車(che)(che)輛(liang)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)控系統出現故障，或者電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)組發生(sheng)碰撞、變形，導(dao)(dao)致電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)內(nei)部元器件損壞及正(zheng)負極(ji)短路，純電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動汽(qi)車(che)(che)仍然存在自(zi)(zi)燃(ran)爆(bao)炸(zha)的(de)(de)風(feng)險。所以(yi)大(da)家在使(shi)用純電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動汽(qi)車(che)(che)汽(qi)車(che)(che)的(de)(de)時候要注意防范。

二、電動汽車如何防自燃

1、一定(ding)要定(ding)期給(gei)電池進行(xing)保(bao)養(yang)。

2、給汽車充電的(de)時候，一定要(yao)確認汽車周(zhou)圍的(de)環境是安全(quan)的(de)，沒有易燃易爆的(de)物(wu)品。

3、汽車充(chong)電的時(shi)候一定要用(yong)標(biao)準的充(chong)電頭，避免長時(shi)間充(chong)電。

4、炎熱的夏(xia)季最(zui)好將(jiang)電動汽車(che)停在通(tong)風(feng)陰涼(liang)的地方(fang)，盡(jin)可能避免(mian)長(chang)時間陽光曝曬。

5、一定要避(bi)免車輛(liang)電池組碰撞的發生。

6、避免長(chang)(chang)時間駕(jia)駛(shi)，長(chang)(chang)時間駕(jia)駛(shi)會(hui)導致電(dian)池負荷(he)增大(da)，適時在服務(wu)區(qu)休息讓電(dian)池降溫。

三、純電動汽車發生自燃怎么處理

1、發現車(che)輛著火，如能切斷(duan)(duan)電(dian)(dian)(dian)源，必(bi)須立即(ji)切斷(duan)(duan)電(dian)(dian)(dian)源，并將鑰匙放(fang)在信號(hao)屏蔽的(de)地方(fang)，最好(hao)放(fang)置到距離車(che)輛10米(mi)以外的(de)地方(fang)。電(dian)(dian)(dian)動汽(qi)車(che)一旦(dan)脫離鑰匙，會自動斷(duan)(duan)電(dian)(dian)(dian)鎖車(che)，降低了電(dian)(dian)(dian)氣系統(tong)帶電(dian)(dian)(dian)引發故(gu)障的(de)可能。

2、動(dong)力電(dian)池(chi)(chi)(chi)著火(huo)后很難撲(pu)滅(mie)，因為大(da)部(bu)分動(dong)力電(dian)池(chi)(chi)(chi)都是鋰電(dian)池(chi)(chi)(chi)，可能需要24小時(shi)才能撲(pu)滅(mie)火(huo)情。如果冒(mao)煙，證明(ming)電(dian)池(chi)(chi)(chi)內部(bu)溫度仍然(ran)很高，隨時(shi)可能有復燃(ran)的情況，此時(shi)一定要密(mi)切關(guan)注電(dian)池(chi)(chi)(chi)情況，并(bing)及時(shi)致電(dian)消防部(bu)門(men)，以便消防部(bu)門(men)盡快撲(pu)滅(mie)火(huo)災(zai)。

3、車輛(liang)著火時(shi)，盡快(kuai)遠(yuan)離車輛(liang)，注(zhu)意(yi)防止高溫和有毒(du)氣體(ti)(ti)，因(yin)為動力電池一(yi)旦著火，會發生彎曲、變(bian)形、損壞，并(bing)伴有大(da)量(liang)有毒(du)氣體(ti)(ti)，如氰化氫(qing)、氟化氫(qing)等，此(ci)時(shi)一(yi)定要注(zhu)意(yi)自(zi)身(shen)安全。

4、行駛(shi)中如(ru)發生碰撞、自燃，應盡(jin)快(kuai)切斷(duan)電源并離開(kai)車(che)輛。如(ru)果(guo)車(che)門變形(xing)打不開(kai)，可(ke)用(yong)車(che)內可(ke)用(yong)的東(dong)西砸碎(sui)車(che)窗(chuang)玻璃，從車(che)窗(chuang)逃生。
