UQM Technologies Announces INTETS Availability

April 23, 2002 by Jeff Shepard

UQM Technologies Inc. (Golden, CO) announced that it has successfully completed testing and launched the commercial availability of its integrated electric traction system (INTETS), an advanced propulsion system for battery, hybrid and fuel cell electric vehicles. The INTETS system is the electrical equivalent of a conventional powertrain consisting of an internal combustion engine, transmission and differential.

The INTETS measures 15in x 11in (380mm x 280mm); incorporates internal, epicyclic, single-stage gearing and off-the-shelf internal differential components; features continuous power of 30kW, peak power of 75kW and peak torque of 1,700N-m; includes a brushless permanent magnet motor, inverter/controller and gearing; and registers a peak efficiency exceeding 91 percent. Development funding for the system was provided by the US Department of Energy.

"We're very excited to report these breakthrough results," stated William Rankin, president and CEO of UQM Technologies. "We believe that no other system can match INTETS in overall power density and product efficiency, and we look forward to working with vehicle OEMs worldwide in its application. In addition to this mid-size version, the company has plans for a smaller 25kW unit to power neighborhood electric vehicles and material-handling equipment. A larger, more powerful 125kW version for light trucks and SUVs is also under consideration. The three versions of INTETS will cover the power range that most manufacturers of battery, hybrid and fuel cell electric vehicles are planning to engineer and introduce."
