During the first reporting period, the project has made substantial progress towards its technical and non-technical objectives, laying the foundation for a fully integrated digital framework for battery testing, modelling, and regulatory compliance. Key achievements include the release of an open, community-driven standard for battery test data and the deployment of BattINFO-based metadata schemas to ensure semantic interoperability and FAIR compliance. These outputs underpin the automated exchange of data between experimental facilities, digital twins, and system-level simulation tools, marking an essential step toward universal interoperability across the battery value chain.
Progress has also been achieved in developing the digital twin framework and associated workflows for real-time parameterization, adaptive test reduction, and lifetime and safety prediction. Novel co-simulation capabilities now allow physical and virtual systems to interact, enabling faster, data-driven decision-making and reducing the experimental burden. First implementations of system-level integration via Functional Mock-up Units (FMUs) confirm the feasibility of plug-and-play digital twin deployment in vehicle and marine powertrain simulations. Together, these achievements set the stage for full validation in the next reporting period, supporting both industrial adoption and alignment with EU battery passport requirements.
