  • PNNL Engineer Michael Kintner-Meyer assesses installation of a Smart Charger Controller device into a Toyota Prius plug-in hybrid electric vehicle (PHEV). The Controller tells the car's battery when to start and stop re-charging based upon existing stress in the electric grid.

RICHLAND, Wash. — The Smart Charger Controller was designed to monitor and mitigate peak demand on the grid as many electric vehicles charge at the same time. Developed at Pacific Northwest National Laboratory, the device uses a low-range wireless technology to communicate with the power grid and determine the best and cheapest time to recharge vehicles. The technology inside the controller also senses stress conditions on the grid and can temporarily stop charging the vehicle until the stress subsides, preventing brown-outs and serving as a large-scale shock absorber. Using this technology, America’s existing power grid could meet the needs of about 70 percent of all U.S. light-duty vehicles if battery charging was managed to avoid new peaks in electricity demand.

On Friday, 15 May, Dr. Michael Kintner-Meyer will explain how smart charging technology benefits customers, utilities and the grid at the meeting of the Electric Vehicle Symposium in Stavanger, Norway. Visit PNNL’s YouTube channel to get a sneak peak of the technology in action.
