摘要： 本文通过对车库环境进行单车和并排双车实体燃烧试验，采用124路热电偶和两侧对称热流计探究火灾演变和蔓延特征，观察烟气蔓延和燃烧痕迹特征，研究多种火灾抑制技术对电动汽车火灾的抑制效果。结果表明,热失控引发的电动汽车火灾由起火电池沿底盘向四周蔓延，烟气在天花板形成厚厚的烟层；按传统车库设置的各种水灭火设施只能抑制火灾蔓延，无法扑灭火灾；电池单体的总体烧毁率为49％。

Abstract: In this paper, entity combustion tests of single vehicle and two vehicle side by side are carried out in the garage environment. The fire evolution and propagation characteristics were explored by using 124—channel thermocouples and symmetrical heat flux meters on both sides, and the characteristics of smoke propagation and combustion traces were observed, and the suppression effect of various fire suppression technologies on electric vehicle fires was studied. The results show that the combustion process of electric vehicle fire caused by thermal runaway spreads from the igniting battery along the chassis to the surrounding areas, and the smoke forms a thick layer of smoke in the ceiling. A variety of water fire extinguishing facilities according to the traditional garage set up can only inhibit the spread of fire, but cannot extinguish the fire. The overall burnout rate of the battery cells is 49%.
