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).

Mobilize launching first commercial V2G service starting in 2024 with Renault 5; France, Germany and UK initially

Green Car Congress

In addition to reinjecting electricity into the power grid, the bidirectional charger supports a vehicle-to-load (V2L) function for powering electrical appliances directly from the car. Mobilize V2G will also be available on future Renault electric vehicles.

DOE awards $200k to support NCSU project on extreme fast charging for EVs

Green Car Congress

The XFC charger this project seeks to develop and demonstrate will be an ultra-low cost, all-silicon carbide modular power converter for direct current charging equipment which can connect directly to a medium-voltage distribution system. This approach eliminates the 60 hertz transformer that normally steps the grid voltage down to 480 volts.

Continental to launch 3rd generation of power electronics for hybrids and EVs in August

Green Car Congress

The system is a key component in every electrified drive, as it supplies both the electric motor as well as the high-volt battery with electricity—when the electric motor works as a generator and feeds electricity into the battery (recuperation). The two central components in the power electronics are the inverter and the DC converter.
