Market share of electrically propelled vehicle is increasing due to high oil prices and environmental concerns. These electrically propelled vehicles demand to ensure high safety of electric energy storage system, high voltage system and mechanical structure which is equivalent to existing ICE vehicle.

Due to these social demands, UN/ECE WP29 GRSP established the Electric Vehicle Safety (EVS) Informal Working Group (IWG) in 2012 and finished phase1 discussion to enact Global Technical Regulation (GTR) for safety issues of electric vehicle by 2016.

Fire resistance test for REESS which is one of the test items of UN R.100 was proposed to EVS GTR. Since Korea proposed the LPG burner fire test of Korea Motor Vehicle Safety Standard (KMVSS) as an alternative to the gasoline pool fire test of UN R.100, this study was carried out to prove the equivalent thermal energy between the gasoline pool fire test and LPG burner test.
