Backend, Roaming, and Plug&Charge ReadinessG&C has focused on making its backend V2G-ready. This includes working on the transition from OCPP 1.x to OCPP 2.x, with OCPP 2.0.1 already implemented and used as the foundation for further OCPP 2.1 development. The core of OCPP 2.1 has already been implemented, while the remaining modules are planned for the coming months. Certificate handling in ISO 15118-20, a key building block for Plug&Charge, has also been successfully deployed. Testing is scheduled to be conducted at the Hubject testing facility; preparations are currently underway, though live testing has not yet started. In parallel, partners are defining system interfaces and protocols for data exchange, including user preferences, contract data for roaming, charge detail record generation for the token award system, and API support for user application development. Meanwhile, Hubject has been working on the overall system architecture, as well as the functional and non-functional requirements for roaming, Plug&Charge, and smart charging platform components. This includes an analysis of OCPI 2.2.1 and its support for smart charging and bidirectional power transfer services. Further work will focus on OCPI-based requirements engineering, partner interfaces, technical and contractual business flows, and assessing the feasibility and scope of early V2G testing with Ambibox for the Berlin site.
Charging Hardware and DC Microgrid DevelopmentTEKNIKER has advanced the design of the charging infrastructure and hardware. The conceptual design is finalized, commercial components have been selected, and PCB routing is underway. For the DC microgrid, the conceptual diagram has been prepared, commercial components have been chosen, and detailed design work is in progress. Individual commercial converter elements are currently being tested, giving the team access to the internal technical data needed for further design and integration stages. STANSOL has purchased bidirectional DC/DC converters for the Spanish pilot. The team has also been working alongside Mobility Lab and TEKNIKER at the Technology Park to review site conditions, drainage channels, meter room access, electrical requirements, mounting options, cooling approaches, and canopy material suppliers. Next steps include completing supplier selection for canopy materials, executing installation and electrical works, preparing the project proposal for permits from Iberdrola, and purchasing two commercial EV chargers. V2G Manager, Forecasting, and OptimisationIREC has developed the initial V2G manager software architecture, which coordinates virtual charging session generation, grid analysis, and optimisation. The optimal V2G scheduling problem has been implemented as a mixed-integer linear programme, providing a structured way to optimise charging and discharging behaviour while respecting operational constraints. Additionally, an initial grid analyser has been developed to evaluate charging power limits based on distribution grid conditions. IREC has also defined the interaction between the grid planner and grid analyser for long-term planning studies.
Forecasting work has progressed on two fronts:
| • | EV charging session forecasting using boosting models such as XGBoost. |
| • | PV generation forecasting using a combination of boosting models and sequence models, such as Long Short-Term Memory (LSTM) networks. |
IREC has also prepared a draft graphical user interface for presentation purposes, completed a study on the arbitrage value of V2G in public charging infrastructure, and established data exchange features with G&C. Tokenisation and Award SystemThe NEVERFLAT award system has officially entered the implementation phase. The system will allow users to earn tokens for eligible charging and energy-positive behaviours, with token transactions secured on the Polygon blockchain. Smart contracts have been designed and deployed, with the treasury wallet securely holding 100,000 tokens. Backend implementation has also commenced, including award logic, spend logic, a demonstration user interface, and an admin interface for managing the system. This work directly supports the wider NEVERFLAT objective of developing value-added services and incentive mechanisms linked to smart charging, V2G participation, and user engagement. |

Pilot-site preparation
In Berlin: TUB has received an official commercial offer for V2G chargers from Ambibox. A potential final installation site for Phase 1 testing has been identified at ringberlin. Technical implementation discussions have covered grid connections, civil works, and responsibilities for installation and operation. TUB is also clarifying the leasing and operation model for a V2G-capable vehicle.
In Bucharest: BEIA is working on obtaining construction permits for a 350 kW medium-voltage transformer for the Mennekes charging station. BEIA has installed an Elecq Home charging station and is currently collecting data through the Home Assistant platform. The site is also preparing for the NEVERFLAT prototype, which is expected to include an AC/DC converter, a DC/DC adapter, and a prototype 7 kW charging station supporting V1G and V2G use cases.
In Alba Iulia: The pilot location at Dorin Pavel Technical College has undergone preparatory upgrades. Defective components from older photovoltaic systems have been removed, the system phases have been balanced, a new 20 kW photovoltaic system with a 13.8 kWh storage battery has been installed, and two new 11 kW systems are in final testing. A 7 kW AC slow charger has also been installed to support a baseline comparison with the future NEVERFLAT station. The Alba Iulia site is preparing technical documentation for a complete energy monitoring system to capture local electricity production and consumption data. As the site does not feature a DC microgrid, the NEVERFLAT configuration will include an AC/DC converter, a DC/DC adapter, and a prototype 7 kW DC station supporting V1G and V2G use cases.
In Vitoria-Gasteiz: Mobility Lab reported ongoing design work with TEKNIKER and STANSOL, alongside continued permit preparation with the Technology Park for installation around project month 24. A user survey has been launched, receiving a high number of responses, and a workshop with potential end users has been planned. Across the Spanish pilot, STANSOL, Mobility Lab, and TEKNIKER are closely coordinating on infrastructure design, permitting, supplier selection, and practical installation requirements-including canopy materials, electrical work, mounting, and cooling.

User workshops at pilot sitesNEVERFLAT has started running user workshops at pilot sites to gather early feedback from potential users before full pilot activities begin. These sessions are designed to understand how users perceive smart and bidirectional charging, including what factors drive acceptance, what concerns may arise, and what could create resistance in real-life contexts. A recent workshop was hosted by Mobility LAB Vitoria-Gasteiz together with Ingartek, engaging potential users linked to the Álava pilot environment. The session focused on user perceptions of smart and bidirectional charging, collecting practical input on expectations, barriers, and everyday mobility needs. This activity supports the project’s user-centred approach by ensuring technical development is informed not only by infrastructure and system requirements, but also by the views of the people who will interact with the solutions. The feedback gathered will contribute directly to pilot preparation, user acceptance analysis, and the refinement of future demonstration activities across all NEVERFLAT pilot sites. |
