Modeling the Thermal Runaway Behavior of Li-ion Batteries upon Mechanical Abused Loading

This presentation demonstrates Altair’s capability of simulating the behavior of a mechanically damaged battery from a cell to a pack integrated in a vehicle, based on collaborative research previously conducted with MIT. An innovative approach of applying electromagnetics loss to predict rising temperature due to short circuit effects during an impact is discussed, along with the development of a software tool, Battery Design, which enables OEMs and suppliers to design battery applications using multiphysics optimization, including mechanical-electrical-electrochemical-thermal behaviors.
