Sandia team develops GaN diode that is significant step toward protecting grid from EMPs

Green Car Congress

Scientists from Sandia National Laboratories have developed a new gallium-nitride (GaN) diode that can shunt excess electricity within a few billionths of a second while operating at a record-breaking 6,400 volts—a significant step towards protecting the nation’s electric grid from an electromagnetic pulse (EMP). —Bob Kaplar.

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.

DOE to fund research to reduce costs of high-voltage direct current (HVDC) transmission

Green Car Congress

Many renewable resources are in remote locations on land, or planned far from shore (e.g. offshore wind), and HVDC transmission provides a solution for renewable integration onto the grid. HVDC transmission requires converters to switch the power from AC to DC and back again to connect to the grid.

ANSI releases for public comment draft roadmap of standards and codes for EVs at scale

Green Car Congress

The roadmap’s primary focus is on light duty, on-road plug-in electric vehicles (PEVs) that are recharged via a connection to the electrical grid, as well as the supporting charging infrastructure needed to power them. Topics covered include standards to address high power DC charging; storage (i.e.,

ANSI to develop roadmap of standards and codes for EVs at scale

Green Car Congress

The priorities of the codes and standards effort will be to identify the most critical standards for EVs at scale, including for standards to address high-power DC charging, storage (i.e., The EVs@Scale lab consortium formed in response committed to develop a 2022 roadmap like the earlier ANSI EV standards roadmap.

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.

The EV Transition Explained: Can the Grid Cope?

Cars That Think

There have been vigorous debates pro and con in the United States and elsewhere over whether electric grids can support EVs at scale. grid, but the rising number of EVs will test the local grid’s reliability at many of the 3,000 electric-distribution utilities in the United States , which themselves own more than 5.5
