Since late 2006, Denise Gray has been the director of global battery systems engineering at General Motors and one of the key people working to bring the Chevrolet Volt to fruition. Gray has overseen all of the testing and development of batteries going into plug and non-plug versions of GM hybrids and extended-range electric vehicles. Gray has also worked with battery suppliers to evaluate new cell technologies that may be used in production vehicles in the future. We've also spoken with her on
We've spoken with Denise Gray, GM's director of Hybrid Energy Storage Systems (she's working to get the hybrid taken out of her title, considering the whole E-REV thing), about the Chevy Volt's batteries many times in the last year or so (read our talks from August 2007, November 2007, and January 2008).

Those lithium ion and nanotech batteries aren't going to create themselves, you know.
