Current Phase Of Performance Evaluation To Focus On Operating Characteristics In Harsh Winter Conditions


FREDERICK, COLORADO, January 22, 2003… UQM TECHNOLOGIES, INC. (AMEX: UQM), a developer of alternative energy technologies, announced today that one of the U.S. Army technology demonstration hybrid electric High Mobility Multipurpose Wheeled Vehicles (HMMWV pronounced HUMVEE®), developed and produced by IDT-PEI Electronics, a unit of Integrated Defense Technologies, Inc. (NYSE:IDE) and powered by UQM® propulsion motors, power electronic inverters and a generator, has begun cold weather evaluation testing at the Cold Regions Test Center at Fort Greeley, Alaska. The hybrid electric HMMWV incorporates one 75 kW UQM® generator and two 75 kW UQM® propulsion motors, one per axle. Each UQM® motor or generator is controlled by a UQM® electronic inverter which manages the operating characteristics of the motor or generator.  The Cold Regions Test Center, a subordinate command of Yuma Proving Ground and the winter test element of the Army Test and Evaluation Command, has the mission to plan, conduct and report the results of winter, mountain and northern environment phases of developmental testing.

The hybrid electric HMMWV is one of four hybrid electric HMMWVs delivered to the U. S. Army for performance testing and evaluation at Aberdeen and Yuma Proving Grounds. AM General, the manufacturer of the HMMWV, is the Prime Contractor. IDT-PEI Electronics is responsible for the complete hybrid drive system design and integration, electronics component design and the energy management system for the vehicles. UQM Technologies provides the propulsion motors, generators and power electronic inverters under subcontract to IDT-PEI Electronics.

During earlier programs, two hybrid electric HMMWVs were developed for proof of concept demonstration of hybrid electric technology. One prototype was configured as a tactical model incorporating a UQM® 55kW generator and four UQM® 75 kW propulsion motors, one per wheel, delivering acceleration from zero to 50 M.P.H. in 8 seconds.  The second was configured as a utility; model incorporating a UQM® 75 kW generator and two UQM® 75 kW propulsion motors, one per axle. This vehicle successfully completed a cross-country trip from Washington D.C. to San Francisco in 2000 to demonstrate vehicle performance and test readiness.

William G. Rankin, UQM Technologies’ President and Chief Executive Officer said, “The initiation of cold weather evaluation marks another milestone in the potential application of hybrid electric propulsion to this class of military vehicle. Successful cold weather and harsh terrain operations is crucial to achieving the HMMWVs mission objectives and we are confident that our hybrid electric propulsion systems will perform well in this demanding round of evaluation testing.”

The Company recently delivered electric propulsion motors, generators and power electronic inverters for two additional hybrid electric HMMWVs capable of submersible operations at a depth of 60 inches below water. By providing submersible operating capability, fording operations are now available in addition to the other benefits of hybrid electric propulsion including stealth operation, reduced fuel consumption and the availability of significant on-board electric power.
