Silicon Carbide Meets Power V2G Demands in EV Fast-Charger Market

This paper explores how silicon carbide (SiC) technology continues to be a leading solution for power and vehicle-to-grid (V2G) demands in the fast growing fast-charger market. V2G is gradually developing as companies innovate compelling business models for powerful energy storage systems (ESS) on wheels. While solar power and stationary ESS will certainly have an important place in the electrified future, V2G is being looked at for dealing with load peaks.
