Delta kicks off DOE-sponsored program to develop microgrid-capable solid state transformer-based 400 kW fast chargers for EVs; XFC

Green Car Congress

The proposed XFC design is expected to offer grid-to-vehicle efficiency up to 96.5%—four —four times less weight and half the size of conventional DC fast EV chargers (DCFC), as well as a high voltage direct current (HVDC) port to utilize energy storage and renewable energy systems, minimizing demand on the power grid.

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

Cars That Think

It occurred in the wake of the California electricity crisis of 2000 and 2001, when mismanaged deregulation, market manipulation, and environmental catastrophe combined to unhinge the power grid. Once electricity is generated and passes into the grid, it is typically used almost immediately.
