Periodic Reporting for period 1 - X-Verter (X-Verter®: Cell-level Controlled Battery System enabling software defined power)

Période du rapport: 2024-12-01 au 2025-11-30

Résumé du contexte et des objectifs généraux du projet

Energy storage is a vital enabler of Europe’s energy transition, supporting renewable energy integration, grid reliability, and environmental sustainability. Battery Energy Storage Systems (BESS) can act as generation, transmission, or distribution assets, enabling cost savings and uninterrupted power supply during grid disturbances. However, conventional BESS architectures face fundamental limitations that reduce efficiency, flexibility, and lifetime.

The objective of the X-Verter project is to industrialise a cell-level controlled power conversion and storage technology that enables direct AC generation from batteries. Beyond efficiency gains, X-Verter is designed as a programmable and adaptable platform that can be configured through software to meet the requirements of diverse users, applications, and implementation areas. The project aims to mature the prototype into a market-ready product aligned with EU priorities on decarbonisation, grid modernisation, and energy resilience.

Travail effectué depuis le début du projet jusqu’à la fin de la période considérée dans le rapport et principaux résultats atteints jusqu’à présent

During the reporting period, the project focused on advancing X-Verter from lab test-bed towards a prototype for on-site customer demonstrations. Key activities included optimisation of hardware design, development of advanced control algorithms, and integration of digital control enabling flexible system configuration.

Functional prototypes were developed and tested to demonstrate step-wise sine wave generation directly from battery cells, validating the elimination of external power conversion stages.

Pre-compliance activities were initiated to set a certification strategy for the product. In parallel, early user feedback was implemented in the development plan to meet the requirements from the market. These activities significantly increased technology maturity and validated the feasibility of a flexible, software-defined BESS solution.

Progrès au-delà de l’état des connaissances et impact potentiel prévu (y compris l’impact socio-économique et les conséquences sociétales plus larges du projet jusqu’à présent)

The X-Verter advances the state of the art by combining cell-level battery control with a highly programmable and adaptable power conversion architecture. Unlike conventional BESS, the technology enables direct AC generation with minimal conversion losses, improved fault tolerance, and dynamic configuration through software.

The results indicate strong potential to reduce energy losses, extend battery lifetime, and lower total cost of ownership. The adaptability of the system allows a single platform to serve multiple applications, including industrial power systems, microgrids, backup power, and renewable energy integration.

Further steps towards large-scale uptake include extended pilot deployments, full certification for selected applications, industrialisation, and access to scale-up financing. The project establishes a solid foundation for commercialisation in a rapidly growing global BESS market.
