  • from cell to module level
  • cylindric, prismatic and pouch cells
  • electrical testing:
    • external short circuit test
    • overcharge test
    • overdischarge test
  • mechanical testing:
    • nail penetration test
    • shock test
    • drop test
    • crush test
  • thermal testing:
    • thermal propagation
    • overheat test
    • thermal shock test
    • fire test
example thermal runaway testing

battery simulation

multiphysics simulation using LS-DYNA®
  • identification of mechanical, thermal and electrical properties
  • generation of multiphysical battery model:
    • mechanical and thermal properties
    • Randle's circuit
    • simulation of internal short circuit and exothermic reaction (thermal runaway)

safety, performance and pack optimization

  • interaction with component groups
  • characterization of battery pack materials
  • testing of interaction with battery pack components
  • simulation of thermal propagation
  • optimization of safety and performance
