TVA, EPRI Dedicate SMART Charging Station for Electric Vehicles

KNOXVILLE, Tenn. Jan. 25, 2011

The prototype Smart Modal Area Recharge Terminal, or SMART station, developed by TVA and EPRI is among the first public electric vehicle charging stations with all these features. Located at EPRI’s Knoxville Research Laboratory, the station demonstrated its capabilities Tuesday while charging electric vehicles built by General Motors, Mitsubishi and Nissan.

The new charging station features:

  • Six parking spaces (10-space stations are planned for the future), each supplying enough power to charge most electric vehicles in three to eight hours, depending on the make of the vehicle.
  • An electric plug designated as the industry standard by the Society of Automotive Engineers that will accommodate all future plug-in vehicles made for the U.S. market.
  • About 2 kilowatts of solar photovoltaic panels per charging space.
  • About 5 kilowatt-hours of stationary battery storage per charging space to assist vehicle charging and send power to the grid during periods of peak electricity demand. The batteries also will support the local power grid by lessening the effects of charging multiple cars in one location.
  • Advanced measurement and controls that will collect data about charging electric vehicles.

The SMART stations will be used over time to study various aspects of electric vehicle charging, including consumer behavior, the impact on the electricity system, infrastructure design and development, and testing different stationary batteries. TVA and EPRI also will assess electric vehicles’ potential to reduce greenhouse gases and other pollutants.
