Every bidirectional EV charger put in might pay for itself in three years, and earn as much as $15,000 over 10 years, in response to projections from a agency that gives such tools.
Chargers put in for vehicle-to-grid (V2G) operation, permitting EVs to discharge energy again into the grid, have related upfront prices to traditional chargers. However additionally they have the potential to earn cash, Melissa Chan, director of grid options and strategic partnerships at Fermata Power, a tech agency that is developed a V2G platform, stated in a current presentation for the CHAdeMO Affiliation commerce group.
Compared, a traditional unidirectional charger might incur as much as $30,000 over a projected 10-year life span from upkeep prices, in response to Fermata. It underscores how, within the close to future, small fleets—and finally residential customers—might be able to reap the benefits of this expertise to cut back their power and driving prices.
Revel and Fermata Power V2G pilot program utilizing Nissan Leaf EVs.
Fermata not too long ago participated in a V2G pilot program with Revel, which operates moped, scooter, and trip share companies in New York Metropolis. Revel makes use of a fleet of electrical automobiles for its trip share service, and put in Fermata bidirectional chargers at its upkeep and restore depot in New York’s Brooklyn borough for the mission.
The mission concerned three of those chargers and three Nissan Leaf hatchbacks. Below an settlement with native utility Con Edison, the automobiles discharged energy from their battery packs again into the grid from 2:00 p.m. to six:00 p.m. on summer season weekdays—when power demand peaked. Revel earned cash from this, but additionally had the choice to unplug the automobiles in the event that they had been wanted.
The three chargers might ship as much as 45 kw of energy into the grid. By discharging throughout afternoons Monday via Friday, the setup might ship as much as 3 megawatt-hours of energy month-to-month, in response to Fermata. That is with nightly charging of EVs as wanted.

The pilot reveals how V2G infrastructure may very well be enticing to fleet operators, however it’s not essentially relevant but on a big scale. Fermata and Revel had a good settlement with Con Edison, however agreements with native utilities are going to differ broadly as particular person V2G customers negotiate with every utility.
Some progress has been made on enhancing V2G viability not too long ago.
Nissan formally authorized Fermata’s charger as the primary U.S. bidirectional charger for the Leaf earlier in 2022, and California has began to think about V2G charging tech at scale, for grid stability. Though a variety of automakers have confirmed future bidirectional charging, a 2020 rumor that Tesla may attempt to sneak V2G functionality into the Mannequin Y proved to be false, nonetheless.
