On 7 October 2026, the CEI-Sphere workshop “Integration of charging stations in fleet management for V2G Services” will bring together experts in Brussels to examine how charging infrastructure can evolve from a simple energy supply system into an intelligent component of the energy ecosystem. The event will take place from 11:00 to 15:00 at the Regus Brussels Louise Centre and will focus on depot charging, smart charging, V2G/V2X, charging station management systems and the role of digital platforms in coordinating fleets and energy resources.
A key contribution will come from O-CEI Pilot 3, with Martin Engelbrecht from AVL List GmbH presenting the pilot’s work on advanced charging management and V2X functionalities. The presentation will introduce the system architecture developed to coordinate charging stations, electric vehicles, renewable generation, battery storage, and grid-connected energy systems. It will also highlight practical implementation scenarios involving photovoltaic generation and battery energy storage, alongside the evolution towards software-defined charging stations, interoperable communication interfaces and cloud-edge-based energy management.
From charging infrastructure to flexible energy assets
The workshop will address a broader shift taking place across electric mobility. Depot-based fleets, particularly when vehicles are parked for extended periods, can become significant sources of flexibility for the electricity system. Smart charging (V1G), V2G, V2B, and V2X can allow fleets to respond to grid conditions while still meeting operational requirements and ensuring that vehicles are ready when needed. With more than 80% of charging taking place outside public charging infrastructure, fleet depots represent an important environment for this transition.
The CEI-Sphere workshop will explore the digital infrastructure needed to make this possible. At the centre is the development of charging station management systems and digital platforms capable of coordinating real-time information on vehicles, charging infrastructure, renewable generation, batteries, grid constraints and flexibility services. The programme will also examine software-defined charging stations, open interfaces and the hourglass model as foundations for interoperable platforms and stronger cooperation across the European Cloud-Edge-IoT ecosystem.
These topics closely reflect the objectives of O-CEI Pilot 3, which is developing intelligent charging strategies for electric fleet operations in Austria. Led by AVL in collaboration with the Österreichische Post AG and Energie Steiermark AG, the pilot explores how EVs can become mobile energy storage assets, while combining smart charging, V2G, renewable energy and energy management to improve efficiency, reduce emissions and support grid stability.

The workshop is organised in the context of CEI-Sphere, bringing together European initiatives and stakeholders working on the deployment and adoption of Cloud-Edge-IoT technologies. O-CEI’s contribution will provide a concrete pilot perspective on how these technologies can support the integration of electric mobility with increasingly flexible and decentralised energy systems.
