HELIEV participated in the Charging & Battery Summit 2025, held at the Zappeion Megaron on November 29–30, 2025.
Athanasios Tambakos, member of HELIEV’s Board of Directors and scientific associate at CERTH, presented HELIEV’s work for 2025 and also highlighted the latest developments in the fields of electric vehicle charging and batteries. During the presentation, the following topics were analyzed:
• The role of smart charging systems for electric vehicles (V1G)
• The importance of bidirectional charging (Vehicle-to-Grid / V2G) for energy
system stability and flexibility
• The integration of electric vehicles with the power grid and renewable energy
sources
In parallel, application examples from the Netherlands were presented, where bidirectional charging already contributes to balancing the electricity grid, along with research findings from Northern European countries, illustrating user attitudes and behavior regarding:
• Smart charging
• Participation in grid balancing
• Future use of electric vehicles as energy sources
The discussion emphasized that electromobility is no longer just about transportation, it has become a key pillar of the energy transition and a move toward a more sustainable and flexible energy system.
