UQM Technologies Announces Field Testing of Three Hybrid Electric Vehicles Powered By Its 42 Volt Integrated Starter/Alternator Power Assist System

42 Volt Systems Achieve Design Objectives in Both Large and Small Vehicles

GOLDEN, COLORADO, Nov. 30 -/E-Wire/-- UQM Technologies, Inc. (Amex: UQM) today announced that it has developed a proprietary integrated 42 volt power-assist hybrid electric system that is currently under test in three customer vehicles. Field test results validate the achievement of design objectives including improved vehicle performance, reliability and fuel economy. The system includes a starter/alternator unit mounted directly to the crankshaft of the engine and an intelligent electronic inverter that controls its operation. The system provides 700 Newton-meters of engine starting torque in starting mode and power generation in excess of 10 kW/13 hp over a speed range from idle to full speed in alternator mode.

Power-assist represents the ability to dynamically provide additional power-on-demand to the drivetrain of a vehicle to enhance the performance of the engine and vehicle while reducing fuel consumption. The power assist feature provides up to 15 kW/20 hp of power to the engine for a short duration during high engine load conditions. Additional features of the system include high speed engine start capability, regenerative braking and higher levels of onboard electrical power availability to handle increased electrical loads from accessories.

"The development of a 42 volt power-assist hybrid electric system was driven by customer demand for a low cost system capable of meaningful improvements in vehicle performance and fuel economy,' said William G. Rankin, UQM Technologies' President and Chief Executive Officer. "The fielding of these vehicles further demonstrates our industry leading ability to apply our proprietary motor and power electronic inverter technology in a wide array of hybrid electric configurations for broad classes of vehicles to support the varied needs of our customers and their vehicle duty cycles.'

The demand for 42 volt electrical systems for automobiles and other vehicles is being driven by continually increasing electric power requirements for such features as power windows, seats, brakes, seat heaters, music and phone systems, and global positioning devices, to name only a few. In addition, 42 volt systems provide additional benefits such as improved fuel economy, increased power availability and the means to drive under-the-hood accessories such as power steering, pumps and fans with electricity rather than with engine-driven belts.

Additional applications of UQM's proprietary technology in hybrid electric vehicles and its revolutionary direct drive propulsion system for wheelchairs were recently featured on CNBC's "Squawk Box,' in its "Outside the Box' segment which aired on Friday, November 23, 2001. "Squawk Box' is a daily segment that acts as a "pre-game' jump on the business day with live reports from major investment banks and the floor of the New York Stock Exchange. It also works to give investors a competitive 'edge' by tracking emerging trends in business and the financial markets, delving into new cutting-edge products and technologies. Audio and video replays of the broadcast can be accessed on the Company's website at www.uqm.com .
