DOE Lab Develops Smart Charging for Electric Cars
The Pacific Northwest National Laboratory on Thursday said it has developed a smart charger controller designed specifically for charging cars at off-peak times to get the lowest price and ease strain on the grid.
If millions of drivers charged their electric cars during peak times,utilities could strain to meet the demand. In places where there is time-of-day electricity pricing, the PNNL's Smart Charger Controller uses Zigbee wireless networking to get price information and decide on the lowest price for charging.Using smart charging, a car owner could save $150 a year, said PNNL engineer Michael Kintner-Meyer. GM is preparing smart-charging technology to be part of the Chevy Volt electric car due in showrooms in late 2010.
