Abstract

Understanding the cell temperature of batteries while discharging is vital to ensure their safety and prolong their lifespan. Previously, a battery model that utilizes a standard single particle battery model with a coupled 3D heat transfer component has been used to simulate the battery temperature across a 3D space. While this has proven to yield accurate results and be computationally efficient, it lacks the necessary information to describe a battery throughout its life cycle.

Batteries degrade overtime, and this degradation contributes to increased cell temperature. Using the relationship between established battery degradation physics and temperature, accurate heating and cell temperature can be simulated throughout the lifespan of a battery.

These results will be corroborated with a fully 3D model utilizing degradation physics, with the expected outcome being nearly identical cell temperature and electrochemistry but simulated in a fraction of the time.

Biography

Derrick Barger is a mechanical engineering student that is very passionate about reducing our reliance on fossil fuels. After riding his bicycle across the United States over the summer of 2019, he learned about the power of clean energy firsthand and wanted to make a difference. He joined this research project hoping to make a contribution to the field of battery science, and through the guidance of his mentors Dr. Park and Dr. Landers, Derrick has learned about the research process and is focused on designing simulated battery models to be used for experimentation. Derrick plans to pursue graduate school in Norway at the University of Tromso after graduating from Missouri S&T.
