Bidirectional Charging: What It Is and How It Works
In this article, we will discuss what bidirectional charging is, how it works, and the benefits it offers for EV owners and the grid.
Federal facilities and their fleets serve critical missions that may be compromised or require backup power in the event of a grid outage. As the federal government moves toward fleet electrification, site decarbonization, and deployment of local distributed energy resources (DERs), agencies should consider both managed and bidirectional charging.
Bidirectional electric vehicles (EV) employed as mobile battery storage can add resilience benefits and demand-response capabilities to a site's building infrastructure.
In contrast to stationary storage and generation which must stay at a selected site, bidirectional EVs employed as mobile storage can be mobilized to a site prior to planned outages or arrive shortly after an unexpected power outage to supplement local generation or serve as an emergency reserve.
Bidirectional vehicles can also power the grid through 'vehicle to grid' (V2G) to provide various grid services, although the programs to incentivize these grid services are not yet widely in place for vehicle applications.
