UA Researchers Developing the Future of Electric, Hybrid Vehicles


Researchers at the University of Arkansas are developing the next generation of electronics and power modules for electric and hybrid vehicles with help of a $1.5 million grant from the U.S. Department of Energy.

Alan Mantooth, Distinguished Professor of electrical engineering and executive director of the National Center for Reliable Electric Power Transmission (NCREPT), received a five-year award to help build silicon-carbide integrated circuits and incorporate them into advanced power modules for electric- and hybrid-powered vehicles. The project is part of the U.S. Department of Energy’s goal to support research that will lead to the development of efficient and sustainable transportation technologies.

“We’ve had a long partnership with Toyota in its effort to build and refine silicon carbide chargers for the batteries and traction drives in the Prius, perhaps the most popular hybrid car,” Mantooth said. “The Vehicle Technologies Office at DOE, and our collaborators at Oak Ridge National Laboratory, knew about this partnership and understood our pioneering work on solid-state, integrated circuits for this type of equipment. It’s gratifying to be recognized for this work and we’re honored to be part of this bigger project.”

The Vehicle Technologies Office is spearheading an initiative to reduce the cost, weight and volume of the systems that power hybrid and plug-in electric vehicles, while also improving performance, efficiency and reliability. The goal is to encourage consumer demand for these vehicles. The office funds research groups to develop innovative designs for systems that can be easily manufactured and commercialized. The office is part the Energy Department’s Office of Energy Efficiency and Renewable Energy.

Under Mantooth’s direction, NCREPT researchers — including Simon Ang, professor of electrical engineering; Fang Luo, assistant professor of electrical engineering; Yue Zhao, assistant professor of elecrtrical engineering; and Juan Balda, University Professor of electrical engineering — are part of a large team, coordinated by Oak Ridge and Sandia national laboratories.

The team will focus on developing high power-density traction drives as part of the overall engine system. In addition to the electric motor, the power-drive systems of these vehicles include converters and inverters, high-voltage batteries and chargers.
