This example shows how to model a battery pack stacked with 20 prismatic battery cells. A heat transfer analysis will be conducted for the model where it is assumed that one of the battery cells is faulty resulting in significantly increased heat generation in the cell.
Two different cases will be studied, one where the pack is perfectly insulated, except for the front and back faces which are cooled through natural convection with the surrounding air. And also a second case study with added increased cooling at the bottom of the battery pack.
The example tutorial highlights the following features:
- 3D CAD STEP geometry import
- Heat transfer simulation with convective cooling
- Anisotropic material coefficients (thermal conductivity) and using different material properties in different subdomains
- Solution restart (using a previously computed data)
- Evaluation and analysis in given evaluation points
This model is available as an automated tutorial by selecting Model
