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.

LowCVP LCA study finds matching battery size with vehicle use is crucial for the environment

Green Car Congress

For electric and plug-in hybrid vehicles the carbon intensity of the power grid is also a key factor in terms of the vehicle’s full life cycle emissions. However, if a race for bigger and bigger batteries is left unchecked, EVs doing low mileages could undermine some of the potential benefits, the report finds.

New nanoparticle copper compound cathode could enable low-cost, long-life and high-power potassium-ion batteries for grid storage

Green Car Congress

Yi Cui has developed nanoparticle copper hexacyanoferrate (CuHCF) battery cathode materials that demonstrate long cycle life and high power for use in grid storage applications. Short-term transients, including those related to wind and solar sources, present challenges to the electrical grid. A team at Stanford led by Prof.

This Dutch City Is Road-Testing Vehicle-to-Grid Tech

Cars That Think

Unlike those you may have grown accustomed to seeing, many of these stations don’t just charge electric cars—they can also send power from vehicle batteries to the local utility grid for use by homes and businesses. Debates over the feasibility and value of such vehicle-to-grid technology go back decades. Kempton and Letendre’s.
