Integrated Multiphysics Modeling for Improving Li-Ion Battery Pack Safety

Research output: NRELPresentation


Battery CAE tools are effective on evaluating safety design concepts and identify key design parameters preventing cascading failures among batteries. An integrated multiphysics safety modeling framework is developed for large format lithium-ion batteries and applied to provide insights into battery pack behaviors subject to internal short circuits. The impact of the energy released by failed battery cells in the form of gas and ejecta on pack safety is addressed in this numerical approach.
