Computational Fluid Dynamic (CFD) analysis was performed using FLUENT to analyze the fluid thermal performance of a Battery cell container for the Ford Fusion Hybrid Electric Vehicle. The objective of the design was to maintain the cells in their desired operating temperature range with a near uniform temperature among the battery cells in the container, while minimizing energy losses associated with the pressure drop. Groupings of multiple such containers were assembled for bench test confirmation. Excellent agreement was obtained for air side pressure drop between the CFD and hardware physical properties. Multiple design iterations were made to improve the baseline design. Ultimately, the thermal gradient within the physical property was reduced to 1.8°C with a minimal increase in system pressure drop.

Students, as members of Team Paradigm, at the University of Wisconsin-Madison have designed a charge regulating, parallel hybrid electric Dodge Intrepid for the 1997 FutureCar Challenge (FCC97). The goals for the Wisconsin “FutureCow” are to achieve an equivalent fuel consumption of 26 km/L (62 mpg) and Tier 2 Federal Emissions levels while maintaining the full passenger/cargo room, appearance, and feel of a stock Intrepid. These goals are realized through drivetrain simulations, a refined vehicle control strategy, decreased engine emissions, and aggressive weight reduction. The vehicle development has been coupled with 8,000 km of reliability and performance testing to ensure Wisconsin will be a strong competitor at the FCC97.
