In this blog we are going to learn how to build a thermal model for an automotive battery module. The tools to be used are Ansys Fluent and TwinBuilder. A reduced order model (ROM) will be utilized to tie detailed 3D thermal information to the system model.

The modeling strategy is shown below.


Ansys has been spending a lot of effort on easy, accurate and efficient modeling of batteries. The chart below shows the workflow for thermal analyses. 

In this particular model, we have covered the Modules inside the red box. The 30-minute webinar video below provides step-by-step instructions to build and execute a thermal model for a 4p1s battery module.
