Smart charger for plug-in vehicles developed at Pacific Northwest National Laboratory
Developed by Michael Kintner-Meyer and his team over 15 months, the PNNL Smart Charger Controller receives wireless signals that are broadcast by the utility and contain power prices to tell the car when to charge and when to stop sucking juice from the grid. The controller can also sense "stress condidions" and pause charging if a grid overload situation is imminent. Kintner-Meyer said the devices could save plug-in vehicle owners up tp $150 a year in energy costs by taking advantage of off-peak energy prices.
