False Starts: The Story of Vehicle-to-Grid Power

Cars That Think

They wanted to see whether an electric vehicle could feed electricity back to the grid. The company’s president, Tom Gage , dubbed the system “vehicle to grid” or V2G. And EV owners would become entrepreneurs, selling electricity back to the grid. And indeed, that’s how promoters of vehicle-to-grid technology perceive the EV.

PHEVLERs are the Zero CO2 Clean Green Machines of the Future

Green Car Congress

The 2016 Chevrolet Volt with an electric range of 53 miles [ 2 ] is the first commercial car that almost qualifies as a PHEVLER. Slow Level 1 charging [ 11 ] should be used to recharge PHEVLER batteries whenever possible. PHEVLERs make our electric grid more efficient. [ PHEVLERs help support the electric grid.
