Using multiphysics to predict and prevent EV battery fire

Electric vehicles (EVs) offer the potential to meet the world’s transportation demands in an environmentally sustainable way. While mass adoption could reduce reliance on fossil fuels, lithium-ion (Li-ion) batteries still present unique challenges to designers and engineers, particularly in ensuring safety against battery fire.

To achieve vehicle manufacturers’ ambitious adoption goals, battery safety must be improved by better understanding the complex, interconnected behavior of batteries under both normal and extreme duty cycles.

Siemens is focused on developing a comprehensive understanding of automotive battery safety by combining innovative design methods and simulation tools to model mechanical damage phenomena as well as thermal and electrochemical runaway. This approach enables accurate computational models and engineer-friendly methods to support safer battery design.
