Performance test equipment UL 2596

temperatureautomaticfor battery enclosure

UL 2596 is a test method for thermal and mechanical performance of battery enclosure materials, evaluates electric vehicle (EV) battery enclosure materials. It provides two test methods: • Torch and Grit (TaG) Test The test specimen is exposed to 3kW flame and grit blast generated by a torch burner, in 20 cycles. The temperature and mechanical damage are monitored to determine the material performance. • Battery Enclosure Thermal Runaway Test The test specimen is exposed to the thermal runaway generated by 25 pieces of 18650 battery cells, which 2 of 25 battery cells are tigered by heated film. The temperature, pressure and mechanical damage are monitored to determine the material performance. The test methods simulate the temperatures, pressures and jet flames that may impact to the enclosure material when the battery undergoes thermal runaway. It enables testing of the material with a sheet material instead of an entire battery assembly which can reduce development cost and time. Torch and Grit (TaG) Test Equipment • Integrated test bench, with an opening test platform to reduce heat accumulation. • Test area with a surrounding safety shield, liftable design, convenient for specimen installation and equipment maintenance. • A stainless steel hood mounted above the test platform, collects the combustion gases during the test. Ventilation capacity is adjustable. • USA torch burner, generates jet flame and grit blasting flame. • The burner has a diameter of 28.6mm, with 30 gas supply ports and 78 oxygen supply ports and central grit blasting supply port. • The burner supplies a 3kW test flame and with/without a grit blasting at a speed of 1.5g/s.
