Mitigating Thermal Runaway in Electric Vehicle Battery Packs: The Role of noCnX in Design-Level Predictions through CAE Simulations

Thermal runaway, a phenomenon characterized by uncontrolled temperature escalation within the battery, poses a serious threat to the safety and performance of EVs. Addressing this challenge requires a comprehensive understanding of the intricacies of thermal dynamics within the battery pack, and advanced simulation tools play a pivotal role in achieving this goal.

CAE simulations, particularly 1D and 3D Computational Fluid Dynamics (CFD), offer a powerful solution to predict and mitigate thermal runaway issues at the design stage. noCnX, a leading provider of simulation-based design solutions, has emerged as a key player in this domain.
