Electric Vehicle

Electric Vehicle (EV) fire

Difference Between BEV and ICEV Fire

  • Differences in the rate of fire progress due to differences in combustible materials

  • In the case of BEVs, more than one-fifth of the vehicle's weight consists of batteries, which suggests that there are more combustibles than vehicles with internal combustion engines

  • In the case of a vehicle with an internal combustion engine, there is a distance between the engine, which is the fire source, and the fuel tank, which is a combustion product, so that the fire must spread

  • Analyze the difference in the fire development pattern of conventional internal combustion engine vehicles (ICEV) and electric vehicles (EV)

  • In the event of an actual fire, the pattern of fires in tunnels and underground parking lots classified as dangerous spaces is identified and the risk factors necessary for rescue are analyzed
