Application Relevant Fire Test Procedure for Battery Pack Protection
AZL Engineering Service
Material Strength Test
- 3 different temperatures: 800°C, 1000°C, 1200°C
- During exposure to fire: tensile force of 0.5 kN over 10 minutes
- If no failure, increase force up to 5kN
Particle Blast Test
- Equal damage effect of thermal runaway with real battery cell
- Exposure to 1200°C for 80 seconds
- Afterwards 10 seconds blast duration, filling mass 450 g
Test specimen size for both tests is 200 mm x 100 mm, flame exposure along the full specimen width Approx. 10 test specimens required, 2 for each tests and temperature
