The ProMoBiS joint project aims to develop and optimize an advanced, scalable multicell system for lithium-ion batteries. This system will be validated through application-oriented testing and supported by modeling and simulation. To maximize performance, external sensors will be fully integrated into the system, allowing for a precise assessment of their added value. Additionally, the effectiveness of the battery management system (BMS), which leverages innovative algorithms, will be demonstrated. This combination of integrated sensors, cost-effective microelectronics, and intelligent algorithms is a unique feature in the market, offering improvements in battery performance, cost-efficiency, safety, and sustainability.

To achieve these goals, the project involves designing and building a testable multicell system in hardware. This includes functional components such as assembly and connection technology, external cell sensors, data communication systems, and cooling mechanisms. The system will be managed by a BMS with advanced temperature management capabilities.

Forschungszentrum Jülich (FZJ) focuses on simulation and modeling efforts, including the development, parameterization, and validation of impedance-based diagnostic methods for cells and battery packs. FZJ is also working on the development, parameterization, and validation of aging models and predicting aging effects at the battery pack level. FZJ contributes to other modeling and simulation tasks as well.
