Abstract of thesis

This study focuses on making electric vehicle (EV) batteries safer by understanding and predicting thermal runaway, a serious concern. Using GT-SUITE software, we simulated how Li-ion battery cells behave under extreme heat. Our goal was to learn about the stages of thermal runaway and its importance in battery safety.

We created models for the chemical and thermal processes causing thermal runaway and put them into GT-SUITE. This helped us predict when thermal runaway might happen and how quickly it progresses. We also looked at how gases are released during this process.

By doing this, we gained insights into how battery safety can be improved. This research is a step forward in understanding and preventing dangerous situations in EV batteries.
