Project overview
The Visegrad group for Vehicle to X
The transformation of our energy systems to renewable energies poses many challenges. One challenge is that renewable energy fluctuates largely over time and needs to be balanced to match demand. The Vehicle-to-Everything (V2X) technology offers a solution by allowing cars to draw energy from the grid to recharge their battery. Or send it back to the grid. The V4Grid project addresses regulatory challenges and a lack of understanding of this technology. The partners pilot V2X chargers in seven regions and develop policy recommendations to inform public authorities about V2X potentials.

About the project
The V4Grid project explores several key use cases of V2X technology, including Vehicle-to-Home (V2H), Vehicle-to-Building (V2B), and Vehicle-to-Grid (V2G). In these use cases, energy stored in EVs will be used to provide power back during outages or peak demand.
Tested under various real-world circumstances, these use cases are expected to deliver significant benefits, including providing backup power, reducing costs, optimizing energy management, supporting grid stability, and facilitating the integration of renewable energy sources.
The results from these tests will contribute to the development of policies that encourage the adoption of V2X technologies, advancing the transition to a more sustainable, decentralized energy system.

Outputs
Vehicle-to-Grid use case
While defining the third key use case, Vehicle-to-Grid (V2G), we focused on how EVs can actively support the grid. Unlike traditional charging, V2G enables vehicles to return electricity back to the grid, helping to balance fluctuations in supply and demand, enhance grid stability, and optimize the use of renewable energy. This approach not only reduces reliance on fossil fuels but also creates new opportunities for more flexible energy management. Within our project, we will explore how V2G can transform EVs into dynamic energy assets, benefiting both grid operators and EV owners while driving the transition to a more sustainable power system.

Vehicle-to-Building use case
Another key use case we defined is Vehicle-to-Building (V2B), which will be tested in various commercial and public buildings. This technology enables a bidirectional energy flow between EVs and buildings, allowing vehicles to store excess energy and discharge it when demand is high. By integrating V2B into energy management systems, businesses can lower electricity costs, reduce grid dependence, maximize renewable energy use, enhance energy flexibility, and provide backup power through EVs. In V4Grid, we aim to explore how V2B can contribute to more efficient and resilient building operations.

Vehicle-to-Home use case
In activities 1.1 and 1.2, we defined three use cases, including Vehicle-to-Home (V2H), which will be tested at five pilot sites. This technology transforms EVs into mobile energy hubs, enabling them to power homes, store excess solar energy, and reduce grid dependence. Key KPIs include lower peak energy consumption, reduced grid capacity demand, and overall energy cost savings. Additionally, where solar PV is available, we will assess how V2H maximizes self-consumption of renewable energy, making home energy use even more efficient and sustainable.

Collaboration Across Borders
Thanks to the collaboration of partners from Poland, Hungary, the Czech Republic, and Slovakia, the project incorporates a comprehensive approach to implementing V2X solutions. The involved partners met in person at the kickoff meeting and have since stayed in touch through regular status updates. By sharing expertise, aligning regulatory policies, and adapting to diverse conditions, this partnership is developing solutions that go beyond national borders.

Defining Key Benefits and Goals
By identifying specific use-cases like Vehicle-to-Home (V2H), Vehicle-to-Building (V2B), and Vehicle-to-Grid (V2G), the project offers tangible benefits to consumers, businesses as well as the grid. The V2H model helps EV owners reduce energy costs, V2B optimizes energy use in buildings, and V2G improves grid stability. All of these models support the use of clean energy, reduce emissions, and contribute to a sustainable energy future.

First Period Completed: Strategic Path for V2X Adoption
The first phase of the V4Grid project involved everything from setting clear goals to designing technical solutions. Our efforts during the first few months have laid the foundation for meaningful collaboration, which is essential for driving innovation to a sustainable energy future. Creating a strong, clear, and transparent strategy was a crucial step for this project and formed the foundation for all subsequent activities. Based on an analysis of the current market, trends, models, stakeholders, as well as limitations and regulations, we were able to define the applications of V2X concepts. Equally important was clarifying the chargers themselves — their specifications, use cases, and their role within the larger energy system.
