As Battery Electric Vehicles and both Hybrid and Plug-In Hybrid Electric Vehicles become more and more prevalent on the market, battery temperature control remains a major vehicle thermal management design focus.

This presentation introduces methods and value in performing cooling analysis using fully CAD-Embedded Computational Fluid Dynamics (CFD) to allow earlier thermal performance prediction. Particular applications include initial battery packaging studies and exploring integration with the vehicle structure. An air-cooled battery pack system example is simulated using FloEFD for Siemens NX. The presentation demonstrates time saving studies to determine the effects geometric design changes on cooling capacity for maintaining proper mean temperature and temperature distribution throughout the pack.
