UQM Technologies Receives $1M Contract Supplement to Continue Development of Controller for Electric Truck

UQM Technologies has been awarded an additional US$1-million contract supplement to an existing US Air Force contract to convert a conventional one-half ton pickup truck to all-electric operation using an optimized configuration of currently available advanced technologies.

The contract supplement provides funding for an additional vehicle testbed and for the continued development of an electronic motor/generator controller that utilizes high operating temperature silicon carbide power switching modules.

The controller is being developed for the USAF Advanced Power Technology Office of the 542nd Combat Sustainment Wing at Robins Air Force Base in cooperation with the US Army National Automotive Center and Mississippi State University. The USAF expects to field test the controller in the all-electric pickup truck testbeds being built by UQM.

The truck is powered by a UQM 120 kW propulsion system and a lithium-ion battery pack from Valence Technology, Inc. The UQM propulsion motor delivers 650 Nm (479 lb-ft) of torque and has a peak energy efficiency of 96%.

The contract supplement increases the total contract value to $2.83 million and extends the expected completion date to November 30, 2008.

Silicon carbide power modules of the type being developed in this program offer the advantage of substantially higher operating temperatures when compared to traditional silicon modules. This funding supplement will allow us to continue our development of a new generation of motor/generator controllers that use silicon carbide modules and are able to operate in harsher environments. This technology is of significant interest to both military and commercial electric propulsion customers, and we are excited that the Air Force has provided substantial additional funding to move this technology toward commercialization.

—Jon Lutz, UQM Technologies’ Director of Engineering

A major UQM emphasis is developing products for the alternative energy technologies sector including propulsion systems for electric, hybrid electric, plug-in hybrid electric and fuel cell electric vehicles, under-the-hood power accessories and other vehicle auxiliaries and distributed power generation applications.



I am glad to see UQM get the contract. We can engineer and design quality motors here in the U.S. Even though this company makes high priced motors for military contracts, it can contribute to finding a solution in other applications as part of this process.


The amazing thing is I’ ve only really just finished Chapter 1 and I feel like I’ ve put my head through a wringer. So I’ d really like it if you can come and visit me at the funny farm after I’ ve done Chapter 5. Visiting hours are 9- 5 and please don’ t shout at the other patients it freaks them out. Anyway, today’ s mind melt is Exercise 2. 5 and it asks us to…

aging with grace

There are many types of skin diseases are now being discovered by modern technology, maybe the cause is the wide range of pollution over the land. Well, if are you having a problem with your skin, don’ t worry because there are lots of people who are having skin problem too and not only you. This is normal today due to different chemical reactions coming from air that we breathe and from ashes that we encountered in our dialy living. If you have sensitive skin too like me then you must use some antiaging...
