Powering electric vehicles with sunlight

The two-year project, supported by the South Coast Air Quality Management District and involving a number of public and private partners, will build solar arrays, advanced battery storage, vehicle charging stations, an electric trolley, and a grid management system to provide clean energy to clean vehicles efficiently.

The funding, approved Jan. 6, will allow the university to install up to two megawatts of solar arrays and two megawatt hours of lithium battery storage systems at three locations on and near the UC Riverside campus. The solar energy will be used to charge vehicles directly at several sites on campus and additional sites throughout Riverside.

In partnership with the City of Riverside and Riverside Public Utilities, UC Riverside engineers will design methods to direct the solar energy to electric vehicle charging in a way that minimizes loads on the grid and demands for electricity generated from non-renewable resources. The system will support the growth in manufacturing and demand for plug-in electric vehicles.

Additionally, UC Riverside plans to convert a trolley from diesel to electric power to shuttle students and area residents around UC Riverside.

"This major effort further propels the city of Riverside and UC Riverside to the forefront of green energy technology," said Matthew Barth, the director of the Center for Environmental Research and Technology and the principal investigator on the $2 million grant.

The project is one of eight funded by the South Coast Air Quality Management District. In total, the district is committing more than $12 million to renewable energy generation, distribution, and storage projects throughout Southern California.

"We're pleased that AQMD recognized the benefits of this project," said Reza Abbaschian, dean of the Bourns College of Engineering. "This is yet another example of our commitment to smart-grid energy solutions that integrate solar energy generation, battery storage, and distribution that are at the core of the mission of CE-CERT and our new Winston Chung Global Energy Center."

The Winston Chung Global Energy Center is a new venture funded by Chinese inventor, entrepreneur and Fellow of the College Winston Chung. Chung's company, Winston Global Energy, will donate 2-megawatts of rare earth lithium-ion batteries for the project.

Bourns, Inc., which is adjacent CE-CERT, will provide the property for the solar installation, and SolarMax, a partner with the college in a number of research projects, will provide the solar panels.

Balqon, a manufacturer of heavy duty electric vehicles, will assist in the conversion of the trolley and in the installation of the battery storage, charging and distribution system. A similar 1.1-megawatt system is currently being tested by Balqon and CE-CERT researchers in advance of its being used to help power Winston Chung Hall on the UCR campus.

The AQMD project is a unique collaboration between the CE-CERT, its industry partners and the City of Riverside, Riverside Public Utilities and Riverside Transit Agency.

"This project will allow us to help the City of Riverside make a huge leap toward in realizing its Green Action Plan," Abbaschian said. "Our research capabilities, combined with the expertise and resources of our industry and municipal agency partners, promises to provide clean, renewable energy solutions in the years ahead."
