 Working closely with Optima Batteries,
AeroVironment, Bipolar Batteries, and Arias, we were able to solve complex battery thermal
management problems for General Motors. We analyzed thermal and fluid flow behavior of hybrid
vehicle battery packs and provided a specific design for the distribution system so that cool
air could be uniformly distributed to the batteries, while meeting the fan power
requirements.
We also designed and fabricated a battery enclosure for temperature
control of sodium sulfur batteries for the U.S. Advanced Battery Consortium (USABC).
Using vacuum insulation, we fabricated and tested enclosures that met and exceeded USABC
requirements.
For Ford Motor Company, we worked hand-in-hand with its lower tier
supplier, Johnson Controls Battery Group, to assess packaging, fluid flow, and thermal
behavior of a battery pack for a "low-storage" hybrid vehicle. We successfully provided
solutions for structural components for staking batteries, battery spacing, and pressure
drop/fan power requirements and fabricated a battery pack enclosure that "fit like a
glove."
