Packaging and performance of an IGBT-based hybrid electric vehicle

A highly integrated hybrid electric vehicle of the series architecture has been built and tested. The vehicle essentially matches the performance of the stock car on which it is based-including full interior space, range, and dynamic performance. It approaches Federal ULEV targets with the engine in operation, and provides sufficient zero-emission (electric only) range for typical commuting. This is achieved by means of an integrated battery package, an air-cooled traction package, and industrial IGBT drives. The arrangement and package designs are discussed, with an emphasis on the electrical architecture and the power electronic drive trains. Operating results are reported.
