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 5 kN

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
