// IKEBA: Algorithms, software and electronics for battery management systems
The central objective of battery system engineering is the development of algorithms, software and electronics for battery management systems (BMS) to monitor and control electrochemical storage systems. Managed by an industrial enterprise, the research department cooperates with partners from industry and research in the project “Integrierte Komponenten und integrierter Entwurf energieeffizienter Batteriesysteme (IKEBA)” (Integrated components and integrated design of energy-efficient battery systems) funded by the German Federal Ministry for Education and Research (BMBF).
The objectives pursued by the consortium include developing a software-based new BMS architecture and providing integrated software-based methods to design these systems and circuits. Requirements management and model-based architecture for the BMS are represented with UML modelling in the Enterprise Architect environment. Modelling and simulation of a complex heterogeneous system comprising a battery model, electronic components, circuits, process controls, communication channels and BMS software take place in the SystemC-based design environment, COSIDE®, which allows for the creation and evaluation of virtual prototypes. In addition to formulating requirements and battery specifications (see the figure), ZSW is working on the simulation of use cases to check whether the defined requirements, specification and objectives are met by the prototype developed. The defined use cases include cell monitoring, balancing, state estimation, performance and energy forecast, charge controllers, fault detection and diagnosis.
