Most studies of the effects of V2G on battery life show that slower V2G discharge rates lessen degradation, while one study suggested that using vehicles for grid storage could improve longevity. Hydrogen fuel cell vehicles (FCV) with tanks containing 5.6 kg of hydrogen can deliver more than 90 kWh of electricity. Vehicle batteries may hold 100 kWh or more .

1534-486: Is potentially a cheaper alternative. In addition, EV power can facilitate ancillary services such as load-balancing and frequency control, including primary frequency regulation and secondary reserve. V2G requires specialized hardware (such as bidirectional inverters ), has significant energy losses and limited round-trip efficiency, and the charge/discharge cycling may shorten battery life. A 2016 V2G project in California
1593-456: Is sometimes used to refer to the process of buying and selling power stored in a vehicle. Electric vehicles can generally store more than an average home's daily energy demand, and supply emergency power to a home for several days, using vehicle-to-home (V2H) transmission. Though the concept of V2H charging is simple, putting it into action requires a technologically complex system. Charging stations must integrate software that communicates with
1652-440: Is technically simpler than delivering power from an EV battery, which many PEVs are not equipped to do. As of 2024 , most EVs require a separate inverter than the one used to power the propulsion motors in order to output AC power from the battery. UV2G can be extended by throttling other activities such as air heating and cooling. V2G began as vehicle-to-vehicle (V2V) charging, as introduced by California company AC Propulsion in

1888-493: The AC phase is not synchronised with the grid, so the power is only available to "off-grid" load. Plug-in electric vehicles include battery electric vehicles (BEVs), plug-in hybrids (PHEVs), and hydrogen vehicles . They share the ability to generate electricity which is typically used to power the vehicle. However, because cars spend most of the time parked, their energy remains stored. V2G allows some of this stored power to be sent to
1947-535: The Battery Storage and Grid Integration Project initiative. In 2022 the first V2G charger became available to purchase in Australia, but delays in rolling them out occurred due to regulatory processes, each State Power Authority needing to certify them as compliant (following Australian government approval). There has also been limited uptake due to high prices and very few EVs being approved to use V2G (at 2023, only
2006-611: The Danish Energy Association. It explored how to balance the unpredictable electricity loads generated by Denmark's wind farms, then generating approximately 20 percent of the country's electricity, by using PEVs and their accumulators. The aim of the project was to develop necessary infrastructure. At least one rebuilt V2G-capable Toyota Scion will be used in the project. The project was important in Denmark's efforts to expand its wind-power generation to 50% by 2020. According to

Most energy losses are from system components other than

California's grid operator, CAISO , defines four levels of Vehicle-Grid Interface (VGI): V1G involves varying the time and rate at which an electric vehicle is charged.

By 2022, V2X had not yet reached market deployment, except in Japan where commercial V2H solutions have been available since 2012. In 2022, Utrecht was installing thousands of bidirectional chargers in anticipation of the arrival of vehicles that support bidirectional energy flows. By 2023, several vehicles supporting V2X energy transfer had come onto
2596-442: The duck curve. Uncontrolled vehicle charging was shown to exacerbate the duck curve. V2G-Sim reported that, assuming daily V2G service from 7pm to 9pm at a charging rate of 1.440 kW over ten years, V2G would have minor battery degradation impacts on PEVs compared with cycling losses and calendar aging, incremental capacity losses being 2.68%, 2.66%, and 2.62% respectively. In May 2016, Nissan and Enel power company announced
2655-647: The early 1990s. Their two-seater Tzero car featured two-way charging. V2G allows charging and discharging between vehicle and grid. V2G vehicles can provide power to help balance grid loads by "valley filling" (charging at night when demand is low) and " peak shaving " (sending power to the grid when demand is high; see duck curve ). Peak load leveling supports regulation services (keeping voltage and frequency stable) and provides spinning reserves (to meet sudden demands for power). Coupling these services with "smart meters" enables V2G. V2G could buffer variable power sources by storing excess energy and providing it to
2714-652: The economic and technical impacts of the applications on the power system and markets. The project started in August 2016 and ended in September 2018. Starting in January 2011, programs and strategies to assist in PEV adoption were implemented. In 2018, EDF Energy announced a partnership with Nuvve, to install up to 1,500 V2G chargers. The chargers were to be offered to EDF Energy's business customers and at its own sites to provide up to 15 MW of energy storage capacity. In October 2019,
2773-508: The electricity grid, lessen the need for power plants, and reduce gas and particulate pollution and carbon dioxide from exhaust emissions. In 2017, at the University of California San Diego , V2G technology provider Nuvve launched a pilot program called INVENT, funded by the California Energy Commission , with the installation of 50 V2G bidirectional charging stations around the campus. The program expanded in 2018 to include
2832-399: The grid during high-load periods. It has been proposed that public utilities would not have to build as many coal-fired and gas-fired power plants to meet peak demand or as an insurance policy against power outages . Local demand is easily measured, so dynamic load leveling can be provided as needed on a highly local basis. Carbitrage, a portmanteau of 'car' and ' arbitrage ',
2891-459: The grid, and reduces the need to take power from the grid. A 2015 report found that vehicle owners could receive significant payments by charging their EVs at off-peak times when electricity is cheaper, storing it in their car battery, and selling it back to the grid at peak times when electricity prices are higher. Batteries have a finite number of charging cycles, as well as a limited shelf-life, so V2G can reduce battery longevity. Battery capacity
2950-457: The market. The Ford F-150 Lightning supports 9.6 kW of V2L or V2H power. Tesla began deliveries of a new light truck Cybertruck offering 11.5 kW of V2H or V2L capability. V2G allows vehicles to supply electricity to the grid, with energy paid for by the operator of the utility or transmission system. In many jurisdictions meeting power demands during periods of peak demand is much more expensive than at other times. Power from EVs
3009-468: The strain on US power grids by as much as 38% by 2050. Coping with this heightened demand presents a significant challenge for both power companies and government agencies. In July 2022, eight electric school buses in the San Diego Gas & Electric (SDG&E) service territory were part of a five-year pilot V2G project to boost reliability during electricity failures. Using V2G software from Nuvve,
