Course Goal / Objective
The aim of this course is to provide an understanding of the thermal behavior and thermal management methods of battery systems in hybrid and electric vehicles and to enable their analysis through numerical modeling.
Course Content
This course covers CFD-based numerical analysis of battery thermal management systems used in hybrid and electric vehicles. Creation and simplification of battery cell and module geometry, mesh generation, evaluation of mesh quality, definition of solid and fluid regions, assignment of material properties, and specification of boundary conditions are explained. Air cooling, liquid cooling, systems including phase change materials, and hybrid cooling approaches are examined with an application-oriented perspective. Thermal analysis setup at single cell and battery module levels, heat generation definition, inlet and outlet conditions, solution settings, and evaluation of results are emphasized. The effects of parameters such as flow rate, channel geometry, cell spacing, temperature distribution, temperature difference, and pressure drop on system performance are evaluated through parametric analyses. Comparison of different cooling strategies, interpretation of model results, and engineering evaluations based on case studies are included.
Course Precondition
There are no prerequisites for this course.
