UQM Technologies Inc, a developer of alternative energy technologies, has been awarded a contract from Eaton Corp under a United States Department of Energy (DOE) contract with Eaton's Truck Business to develop hybrid propulsion components for trucks and other heavy duty vehicles.

Eaton is partnering with International Truck & Engine Corp to develop an integrated, next-generation heavy hybrid propulsion system. UQM's contract is for the development and application of a UQM motor and controller in an International truck with an Eaton hybrid electric propulsion system.

Eaton and International's DOE program provides matching funds for research and development aimed at doubling the fuel efficiency of conventional trucks, while maintaining reliability and durability of components and meeting future federal emissions standards for 2007 and beyond.

Most heavy vehicles currently have diesel engines. Hybrid propulsion systems generally consist of a smaller internal combustion engine augmented by an electric drive, an energy storage system, and regenerative braking or other energy recapture systems. Reliability demands are crucial, as heavy vehicles typically can be driven as much as one million miles over a 10-year period.

The project is part of the 21st Century Truck Partnership, managed by the DOE's Office of FreedomCar and Vehicle Technologies. Information on this and other heavy vehicle technology programs can be found at www.trucks.doe.gov/ and www.ctts.nrel.gov/heavyhybrids/.
