According to Fortune Business Insights, the global Vehicle-to-Grid (V2G) market size was valued at USD 15.59 million in 2025 and is projected to grow from USD 18.10 million in 2026 to USD 93.77 million by 2034, exhibiting a CAGR of 22.80% during the forecast period of 2026–2034. Vehicle-to-grid technology enables electric vehicles to return stored electricity to the power grid through bidirectional charging systems, allowing EV batteries to function as distributed energy storage resources.

Vehicle-to-Grid (V2G) Market Overview

Vehicle-to-grid technology connects electric vehicles with electricity networks to facilitate two-way energy flows. Unlike conventional EV charging, which transfers electricity only from the grid to the vehicle, V2G systems allow stored battery energy to be supplied back to the grid when required.

V2G systems depend on bidirectional chargers and software capable of communicating with grid operators. These systems can help manage electricity supply and demand, support grid stability, and enable EV batteries to store excess electricity generated from renewable sources. The technology can also provide benefits to EV owners through energy cost management and participation in grid-service programs.

Key Market Growth Drivers

Rising Adoption of Electric Vehicles

The increasing adoption of electric vehicles is a major factor supporting V2G market growth. As the global EV fleet expands, the combined battery capacity available through connected vehicles creates greater opportunities for distributed energy storage and grid-support applications.

The growing penetration of plug-in hybrid electric vehicles and other electrified transportation technologies is also increasing demand for smart charging infrastructure. China's new-energy vehicle sales reached around 12.87 million in 2024, representing a 35.5% increase from 2023.

Growing Need for Grid Flexibility

Power grids are facing increasing requirements for balancing electricity supply and demand, particularly as renewable energy sources become more widely integrated. V2G technology can allow EV batteries to absorb electricity during periods of lower demand and supply energy during peak periods.

This capability can support peak-load management, reduce grid congestion, and improve the utilization of renewable electricity.

Integration With Renewable Energy

One of the prominent trends in the V2G market is the integration of EV batteries with renewable energy and grid services. EVs can store surplus electricity from solar and wind generation and discharge it when electricity demand increases.

In April 2025, China launched V2G pilot projects across nine major cities, including Beijing, Shanghai, and Shenzhen, to explore the integration of EVs with renewable energy systems.

Market Restraints

Limited Availability of V2G-Compatible Vehicles

The availability of vehicles capable of supporting bidirectional energy transfer remains a market constraint. Although automakers are introducing more bidirectional charging capabilities, the range of compatible vehicles is still limited compared with the broader EV market.

Lack of Standardization

Differences in charging standards and bidirectional communication protocols can create interoperability challenges. Fragmented infrastructure may make it difficult for vehicles, chargers, utilities, and energy-management platforms to operate seamlessly across different markets.

Market Opportunities

Efficient Power Distribution and Expanded Storage Capacity

V2G technology provides an opportunity to use EV batteries as distributed energy storage resources. Utilities can potentially use connected vehicles to manage peak electricity demand and improve grid flexibility.

The technology also provides opportunities for fleet operators and consumers to participate in energy markets. In June 2025, MyWheels announced the integration of 500 bidirectional Renault EVs, demonstrating the potential for vehicle fleets to operate as distributed storage assets.

Vehicle-to-Grid Market Trends

Increasing Integration With Grid Services

The integration of V2G technology with grid services is emerging as an important market trend. Applications include time shifting, frequency response, reserve services, distribution services, emergency backup, and arbitrage.

Time shifting is particularly important because EV batteries can be charged during lower-demand periods and discharged during peak-demand periods. The time-shifting segment is projected to account for 55.25% of the market in 2026.

Growing Use of DC Bidirectional Chargers

Technological advancements in DC charging are supporting the adoption of bidirectional charging systems. The DC segment is expected to account for 66.30% of the V2G market in 2026, supported by improvements in efficiency, reliability, and interoperability.

Expansion of Individual V2G Applications

Individual EV owners represent another important application area. V2G systems can allow consumers to use their EV batteries to manage electricity consumption and potentially participate in energy programs.

The individual segment is projected to account for 55.25% of the global market share in 2026.
