Dana Developed Air And Liquid Battery Cooling Technologies

Thu Jul 21, 2011 8:20 pm

Dana Holding Corporation is a world leader in supplying driveline products and service parts for vehicle manufacturers. Based in Maumee, Ohio, the company supplies parts for nearly every major vehicle manufacturer in the global automotive markets.

Dana has now developed air and liquid battery cooling technologies for a number of electric and hybrid-electric vehicles, including the 2012 Ford Focus Electric, and continues to develop new technologies to advance development of fuel-cell powered vehicles.

"Dana has great capability in the traditional areas of thermal and sealing technology, and we have leveraged that expertise into new and innovative areas such as electric car and fuel cell development," said Roger J. Wood, chief executive officer and president of Dana. "Alternative power generation for automobiles is going to require the collective efforts of the OEM and suppliers to achieve critical mass. We will continue to support these technologies, not only to participate in the market growth, but also to help create a viable market for green power."

Basically, Dana developed a lightweight fin technology that extends battery life that enables the battery to be charged and cooled simultaneously. The air is able to reach the surface of each cell module because of the patent pending system of flexible aluminum fins. This should provide better technology for the 2012 Ford Focus Electric.

"Using our knowledge of thermal technologies, Dana developed a specialized air cooling assembly that works within the limited space between the battery's tightly packed cells," said George T. Constand, Dana's chief technology officer. "Our engineering expertise allowed us to provide a flexible, custom solution to our customer in order to best meet the unique demands of this exciting vehicle."

The advanced battery cooling technologies have been featured on 16 hybrid-electric and electric vehicles, including the Chevrolet Volt, Ford Focus Electric, Ford Transit Connect, and Tesla Roadster Sport.
Dana will also continue to help advance fuel-cell technologies as part of its green power strategy.
