Résumé des résultats (Abstract) (Anglais)

REBORN project aims to promote the utility of second life battery packs by engaging sophisticated, safe and cost-efficient software and hardware architectures. Towards achieving this goal, the consortium tends to enhance the assembly and disassembly process by providing solderless mechanical interconnections and wireless RF communications among the cells and the BMS. Also, a cyber-secured and optimal data transfer is achieved with cloud based storage. The data analytics are performed based on novel physics-based and AI algorithms in order to obtain ageing performance unique cell indicators with respect to a battery passport concept. REBORN aims to minimize the post-characterization process on the battery packs received from 1st life, and achieve faster screening and sorting based on smart strategies that combine the cell data identifiers from the cloud and ML sorting algorithms. The project will target to mobility and stationary applications, and it will provide an agnostic and technology neutral, regardless of cell chemistry or form factor, modular design methodology. An end-user demonstrator will be built and evaluated in the relevant environment accounting for reconfigurable battery packs. The consortium will deploy semi-automated robotic dismantling strategy based on virtual reality control of the battery packs, that will enable a safer and rapid process. A prospective LCA method will be carried out to understand and quantify the benefits/impacts of using 2nd life battery with the proposed methodology. Ease of use and adaptivity, cost-effectiveness and accelerated processes along with optimal performance and eco-friendliness are among the major objectives of REBORN project to uptake the second usage market.
