Volkswagen Group of America; the University of Tennessee, Knoxville; the UT Research Foundation; and Oak Ridge National Laboratory today announced a partnership to create Volkswagen’s first innovation hub in North America at the UT Research Park at Cherokee Farm. The partnership is leveraging the expertise of ORNL scientists and several faculty members within the Tickle College of Engineering at UT to develop lighter vehicle components made from composite materials and ... read more

For consumer mobile electronics, wireless power transfer (WPT) promises to revolutionize the way users interact with their devices. Ubiquitous, seamless charging is expected to reduce onboard battery storage requirements, and untether mobile devices from periodic wired charging requirements.  At present, commercial implementations of wireless power transfer are largely limited to low power, low efficiency, and a charging paradigm where each device must be well aligned with a dedicated charg... read more

For Knoxville native Spencer Cochran, staying at UT for graduate school was a given.Cochran began his journey at UT after graduating from Halls High School in 2011. During his undergraduate years, a few things pushed him toward an electrical engineering degree.“I always thought I wanted to work on robotic prosthetics,” Cochran said. “The longer I was in school, the more I began to feel like electrical engineering was just as appropriate, if not more appropriate, for that dream.... read more

Oak Ridge National Laboratory announced Thursday that it had successfully demonstrated a new 20-kilowatt wireless charging system for electric vehicles.The lab said the charging system achieved 90 percent efficiency at three times the rate of the plug-in systems commonly used to recharge electric vehicles."This ability can help accelerate the adoption and convenience of electric vehicles," ORNL said in a release distributed to the news media.The Department of Energy laboratory collaborated on te... read more

Cell phone and laptop chargers, electric cars, medical devices: improvement and development of these and other devices are all done by engineers in power electronics.A new $2.9 million grant from the U.S. Department of Energy is helping the University of Tennessee encourage more students to go to graduate school in that discipline with a new graduate traineeship.UT faculty members are developing the courses and other details, as well as recruiting students for the program, which is expected to s... read more

Electric vehicles (EVs) have become fixtures in the car market, both in the U.S. and abroad, but there are hurdles to mass consumer adoption. In addition to continuing to be cost prohibitive to many, EV technology is still in need of advancements in efficiency, particularly at typical performance levels.As of December 2014, the United States possesses the largest fleet of plug-in electric vehicles in the world, with 291,332 highway capable plug-in electric cars sold since the launch of the Tesla... read more

Members of the US Department of Energy including Anant Agarwal, Senior Advisor for Wide Bandgap Technology in the Energy Efficiency & Renewable Energy division visited the University of Tennessee Knoxville to review the newly-formed PoTenntial traineeship program on Friday.  Dr. Agarwal was accompanied by Pawel Gradzki, and Ziaur Rahman, of DOE; Al Hefner from NIST; Laura Marlino from ORNL; and Steve Walsh from Power America.This visit represented an "opening ceremonies" of sorts for th... read more
