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.

JERA and Toyota deploy first large capacity Sweep Energy Storage System with second-life batteries

Green Car Congress

The system was built using batteries reclaimed from electrified vehicles (HEV, PHEV, BEV, FCEV) and is connected to the consumer electrical power grid. JERA and Toyota began discussions in 2018 to establish battery reuse technologies, which eventually led to this large-capacity, grid-connected Sweep Energy Storage System.
