PNNL's Team Smart Charger Controller (IMAGE) DOE/Pacific Northwest National Laboratory Caption Engineer Michael Kintner-Meyer (front) and his team at Pacific Northwest National Laboratory (from left: Nathan Tenney, scientist; Frank Tuffner, engineer; Vilayanur Viswanathan, engineer; Richard Pratt, engineer, developed the Smart Charger Controller (pictured) to manage peak demands in the electric grid once a mass of electric vehicles hit the road. The Controller tells an electric vehicle's battery when to start and stop re-charging based upon existing stress in the grid.
