The Cell-Manager project, which stands for “Cell level integration of power electronics and sensing for enhanced controllability, reliability and performance of future batteries”, recently held its final meeting, marking its successful completion of its mission to develop an intelligent hybrid battery storage system (H-BESS) that addresses the challenges of increasing renewable energy penetration and diversified demand from electric vehicles. By combining high-energy Nickel Manganese Cobalt (NMC) and high-power Lithium Titanium Oxide (LTO) cells at the cell level and controlling them through innovative power electronics and a specialized battery management system, the project achieved significant advancements in efficiency, cost reduction, and system reliability.

Key outcomes include a reduction in costs through optimized cell capacity, an increase in battery lifespan thanks to degradation-aware control algorithms, and an improvement in energy efficiency. The system’s flexibility allows it to adapt to varying demands, from EV applications to grid stabilization, while its modular design enhances fault tolerance. Additionally, the H-BESS reduces environmental impact compared to conventional systems, minimizing reliance on critical raw materials.

These achievements demonstrate the project’s success in creating a scalable, multi-service energy storage solution that supports renewable integration and accelerates the energy transition. Overall, the Cell-Manager project, led by Lluis Trilla from the Power Systems department, has laid a strong foundation for future deployments of cost-effective, high-performance hybrid battery technologies.
