With electric vehicles entering the mass market and stationary energy storages becoming relevant for energy grids with volatile renewable sources, the pace of their introduction depends on the progress of battery pack development. In this context, Battery Management Systems (BMSs) form the critical component from the electronics and software perspective, significantly influencing safety, efficiency and cost of packs. In contrast to the state of the art determined by centrally controlled BMSs, the Smart Cells introduced in this talk are fully decentralized autonomous systems at the cell level, which is the smallest level of granularity possible. Smart Cells combine each battery cell with a dedicated cell management unit and manage themselves individually. For pack-level functions, such as charge equalization between cells, the Smart Cells collaborate by coordinating actions via a communication interface. This novel embedded architecture enables maximum scalability, high efficiency and reduced cost, but poses challenges from the system design perspective. Consequently, for the design of Smart Cells, aspects of self-organizing software systems, communication security and hardware design have to be considered. For this purpose, design automation tools and frameworks for verification, simulation and security have been specifically developed for the Smart Cell architecture and are presented in this talk.


Dr. Sebastian Steinhorst leads the Embedded Systems Group at TUM CREATE Ltd. in Singapore as Principal Investigator. His research centers around hardware-software architecture co-design and design automation of distributed embedded systems in the application areas of smart energy storages, Internet of Things and automotive. Before assuming the Principal Investigator position in 2015, he held Senior Research Fellow and Research Fellow positions at TUM CREATE since 2011. Dr. Steinhorst received his Ph.D. degree in Computer Science with "summa cum laude" (with highest distinction) from the Goethe-University of Frankfurt am Main/Germany in 2011, where he was a Research Associate with the Electronic Design Methodology Group from 2006 to 2011.
