BAE Systems introduces next generation hybrid propulsion system

摘要

USA - BAE Systems of Johnson City, New York, USA used the American Public Transportation Association's Annual Meeting and Exposition (APIA 2008) in San Diego, California, to introduce an improved, yet mechanically simpler version, of its hybrid propulsion system. It also used the show to introduce an optional power system package that can meet all ancillary electrical power requirements and offer zero emission transport for a limited distance. Thomas Webb, for BEA Systems, explained that the new system, which is based on the company's series diesel-electric HybriDrive propulsion system that is already in use by transit agencies across North America, could now be configured with the diesel engine and generator arranged both in-line, or as previously, transversely, making it adaptable to a wider range of bus models. The system consists of a generator, an electric motor, and an energy storage system managed by computerized controls. An engine that turns the generator operates independently of the electric drive motor, thus allowing it to run at nearly consistent speeds for optimum efficiency and minimum stress and wear. The system also uses no mechanical transmission.
