BaSiS – Batteriesicherheitssimulation

Funding sponsor: BMWi

Contact partners : Stefan Doose, Clara Sangrós,

Summary of the project:

BaSiS is a BMWi-sponsored project focused on safety research of lithium-ion batteries. In the context of electromobility, new batteries with aimed enhanced energy density are on the spotlight and it is therefore required that their safety is likewise guaranteed. The early safety assessment of battery materials using predictive simulations is designed to avoid overengineering and targets the reduction of manufacturing costs. Within this framework, the main aspect of this project is the development of a coupled physicochemical DEM-FEM simulation for the evaluation of novel battery materials and their validation via small-scale experiments at the cell level.

Goals and tasks of the iPAT

  • Development of DEM simulations regarding the safety assessment of lithium-ion batteries taking into consideration their mechanical, electrical and thermal behavior
  • Parametrization of the model via characterization of single components and manufactured electrodes
  • Calibration and validation of the model under different load cases: internal short circuit, thermal stress and crushing
  • Verification, improvement and construction of the assembling of the cell compartment considering its mechanical structure
