摘要:
为了探究电动汽车火灾危险性,利用FDS软件建立锂离子电池火灾模型,并对电动汽车锂离子电池组火灾进行数值模拟研究,分析火灾过程中的热释放速率、烟气、能见度、温度、CO和CO2浓度变化规律。研究结果表明:电动汽车内锂离子电池组火灾发展迅速,其烟气、高温、CO等危害影响车内人员的安全;车辆内部锂离子电池组的数量决定其火灾危险性的大小,大电池容量电动汽车火灾风险较高;当电动大巴车后端电池组发生火灾时,人员后门逃离的安全性系数高于前门;电动汽车火灾可能发生蔓延,增大车辆密集型区域的消防安全难度。该模拟结果可为电动汽车消防提供参考。
Abstract:
In order to enhance the understanding of the fire hazard of electric vehicles,a model on the fire of lithiumion battery was established by using the FDS software,then the numerical simulation study on the fire of lithiumion battery pack in the electric vehicle was conducted,and the change laws of heat release rate (HRR),smoke,visibility,temperature,CO concentration and CO2 concentration during the fire were analyzed.The results showed that the fire of lithiumion battery pack in the electric vehicle developed rapidly,and the smoke,high temperature,CO and other hazards affected the safety of people in the vehicle.The number of lithiumion battery pack inside the vehicle determined the size of fire risk,and the electric vehicle with large battery capacity had higher fire risk.When the fire occurred at the battery pack in the rear of electric bus,the safety coefficient of people escape from the rear door was higher than that from the front door.The fire of electric vehicle might spread,which increased the difficulty of fire safety in the vehicleintensive areas.The simulation results can provide reference for the fire protection of electric vehicle.
