Simulating Battery Pack Cooling System using Ansys Fluent — Lesson 3

The battery pack cooling system is used in electric vehicles to remove heat from the battery pack. Battery packs generate heat during operation, and high temperatures can reduce the lifespan of lithium-ion batteries. Batteries also perform better at lower temperatures, so cooling is desirable to keep batteries operating in an optimal thermal range during high use and fast charging cases where usage is high. Overheating of the battery pack could lead to failure of other components and could result in a loss at the competition. Thankfully, we have simulation technology to help avoid overheating.

In the video demonstration, students will learn how to handle battery pack simulations using a multiscale multidimensional (MSMD) battery model and conjugate heat transfer approach in Ansys Fluent. The video will also go over the MSMD battery simulation using the equivalent circuit model (ECM) and parameter estimation tool, as well as a coupled electrothermal simulation of a battery pack cooling system.
