ANN ARBOR, Mich. -- In a packed Stamps Auditorium of the Charles R. Walgreen Jr. Drama Center, University of Michigan students and visitors received a charge from the special appearance of Denise Gray, Director of Hybrid Energy Storage Systems for General Motors.

For just over an hour, Gray addressed the matters of future change and production in an address entitled “GM - Leading the Electrification of the Automobile: Engineering for the 21st Century.” It was during her presentation that Gray discussed in extensive detail a special battery pack that could eventually be put to use by vehicles, such as the new Chevrolet Volt, in the upcoming years.

The product, she said, would be comprised of a lithium-ion combination for the sake of not risking the use of hazardous chemicals, while running on an estimated 300 volts. She added that GM would be the first major automaker to mass produce such batteries in a single facility.


The new batteries will make the GM Hybrid System nearly three times more powerful than the system it replaces. Pictured is 2009 Saturn Vue Green Line with Two-mode hybrid drive.

Dramatic developments in stored-power technology make electric cars more viable than ever. Pictures is Th!nk Global's new Ox crossover vehicle.

Chrysler is looking to develop their next generation of plug-ins to compete directly with GM's upcoming 2010 Volt using GE's 'dual-battery' energy storage system.
