Welcome to the 4th Newsletter of the EV4EU project!

The EV4EU Horizon Europe Programme project involves a consortium of 16 beneficiary partners (+ 6 associated partners) from 4 European countries: Denmark, Greece, Portugal, and Slovenia and demonstration sites are currently installed in all four countries to test the V2X management strategies and tools.

The project has successfully concluded 24 months of activities.

This newsletter highlights the EV4EU activities from December 2023 to the end of May 2024

EV4EU Newsletters are published every six months presenting the activities of the consortium. Subscription form and previous Newsletters are available online on our website

As we wrap up Month 24, we are pleased to present an overview of the project´s latest developments. EV4EU primary mission remains to help shape the future of e-mobility and meet societal needs.

Through the effort of all EV4EU partners, we are committed to contribute to that goal: we have now completed 33 tasks, submitted 61 deliverables, of which 27 have already been approved, published 23 scientific articles, including conference (14) and journal (9) papers, and 8 students have presented their bachelor/master dissertations.

FOLLOW US

During the last 6 months, EV4EU has achieved significant milestones, the 18 months report was

successfully presented with a positive feedback from the PO, the four demonstrator sites are now active and all tasks were initiated.

In April, we reached 1000 followers on LinkedIn and have been growing since then. We have already attended over 40 events and we keep on supporting liaison activities with peer projects to strengthen our joint commitment in developing V2X methodologies to enhance mobility and to support EU energy transition.

Under the EV4EU project we have been able to identify new Business Models and Use Cases to be used in the four demonstration sites, submitted a patent for a of V2X management station, and worked on updates for the charging station management system in parking lots and companies, among other important achievements. Furthermore, all DEMO activities are currently active, and more developments will follow soon including the installation and commissioning og the demos.

The project still has 18 months ahead and we are excited about what is to come.

EV4EU NEWS – Project Progress

The EV4EU project tackles emerging challenges related with the integration of Electric Vehicles (EVs) into the power system, transport sector and society at large. Currently at M24, the project has achieved significant progress and reached important milestones: a patent of the V2X Management Station was submitted, new developments were achieved in the V2X Management platform, EV battery degradation was evaluated under various V2X scenarios and new V2X strategies were tested in Slovenia and Denmark. Below is presented an overview of the project activities undertaken in the last six months. More information about the EV4EU can be found on Cordis and EV4EU website.

PatentofV2Xmanagementstation

The development and patenting of the V2X Management Station was a landmark achievement of the EV4EU project, coordinated by Smart Energy Lab in collaboration with key partners including INESC ID, DTU, NEW, and ABB. The patent application process was focused on creating a replicable and scalable V2X charging infrastructure. The management station's design and functionality align with the broader objectives of the project, including promoting EV adoption, enhancing grid resilience, and the integration of renewable energy sources.

The patent of the cost-effective charging solution has been submitted to Portuguese intellectual property institution.

Characterizationof Batteries degradation considering the participation in V2X services

Led by SEL, EV battery degradation was evaluated considering several aspects such as: battery degradation mechanisms, calendar and cycle aging, and key factors like temperature and state-ofcharge that affect battery life. Using a semi-empirical model (Wang model and the PyBaMM simulation tool) the study simulates battery performance across different grid services. Findings indicate that: frequency regulation demands the most from batteries due to the need for rapid responses, leading to increased cycle aging; afterwards coordination with wind generation avoiding wind curtailment was assessed.

Optimal management of V2X in parking lots

Focusing on demonstration activities led in Denmark regarding the development of V2X strategies, forecast models for predicting EV charging demand and PV system generation were integrated into control models that facilitate coordinated EV charging. These models were tested with real data, ensuring grid compliance and providing demand response services. The structure of the model is shown in Figure 1. A notable result was that reducing the cluster power limit by half during peak hours only slightly decreased the energy fulfilled by EVs. In the summer, 77% of EV energy was sourced from local PV, whereas, in winter, this dropped to 13%.

EV4EU NEWS – Project Progress

Additionally, a distributed control method for frequency regulation demonstrated a 9% faster response than centralized methods. The developed control methods serve as a basis for the upcoming demonstrations in WP9.

Optimal management of EV fleets in companies

V2X smart control strategies were also tailored, under the EV4EU project, to the needs of companies managing their own fleets. The proposed methodology accounts for various EV users, including the company fleet, employees, visitors, and clients. The implemented algorithm will be tested in the Portuguese demonstrator, in São Miguel Island, Azores to evaluate the efficacy of shared charging strategies and the influence of V2X technology within a corporate setting.

Overall, the study demonstrates that strategic management of EV fleets, considering PV integration, V2X technology, and priority levels, can optimize energy use and enhance grid stability.

Impact of mass deployment of V2X in energymarketsandservices

This task outlines the integration of EVs into energy markets, specifically focusing on Slovenian demonstrator.

It reviews services for EV participation in regional electricity markets via a virtual power plant (VPP) and in local flexibility markets. The main aim was to

- analyze market platforms and the current state of the Slovenian flexibility market, identifying key flexibility services and summarizing EV users' perspectives;

- details the development, integration, and benefits of a market platform for the Slovenian demonstrator, including its main functionalities and communication protocols;

- outlines the services to be tested, categorized by their relevance to TSOs, DSOs, and EV users, and discusses their activation and procurement processes;

- review the current status of the energy market and flexibility markets, and relates these to the services for the Slovenian and other EV4EU demonstrators.

OpenV2XManagementPlatform

Details are here introduced focusing on the public charging station management system that has been developed by PPC. Source code was released through the project’s GitHub account. This provides an overview of the platform's backend architecture, covering four levels: the System Context View (stakeholders like EV users and platform managers), the Container View (core and auxiliary services), the Component View (O-V2X-MP Core and OCPP Server), and the Deployment View (microservices). The document emphasizes value-added services such as cybersecurity and data analytics and includes instructions for running and testing the platform, which has been successfully tested with simulators and real EV chargers during live demonstrations. Figure 2 shows the interface of the Database Manager, a webbased GUI that allows the Platform Manager to inspect the contents and administer the relational database, troubleshooting or correcting possible issues and inconsistencies.

Further details about these tasks will soon be shared on EV4EU website under Resources.

EV4EU DEMONSTRATION SITES — Greece

The Greek pilot is based in the Mesogia Area, located in the Attica region of central Greece, which places it at the outskirts of the Athenian metropolis. In this Demo, a more intuitive platform for managing public charging stations will be demonstrated and the impact of electric vehicles on the grid will be investigated.

The main aspects of the Greek demo are the deployment and testing of the Open V2X management platform for public chargers, developed by PPC; the integration and testing of the flexibility algorithms for local and system-wide grid services developed by DTU and INESC-ID, and the investigation of exploitation and marketability strategies for the proposed solutions with the contribution of CITROËN.

To do so, the Demo is being led by HEDNO, with INESC ID, Citroen, PPC and DTU.
