Battery management systems manage these batteries. Typically, battery management systems used to be placed deep within the vehicle architecture, away from external interfaces. However, with increasing connectivity to backend systems, e.g., to improve monitoring battery properties and optimize charging, battery management systems have moved closer to the attack surface, increasing security risks. Also, batteries will soon be reused in so-called second life applications, e.g., as an energy storage system in a private home. While conventional methods involve removing the battery and reusing it with a new battery management system, modern methods retain the original system. Though security controls exist for first and second life applications, there is a lack of research on the transition phase. This paper analyzes the phase of transferring the battery management system from the first to the second life of particular relevance for security, privacy, and intellectual property. We try to close this research gap by analyzing the security aspects of a battery management system life cycle and its altering system environment. We are defining the transition phase, identifying necessary activities, and providing cybersecurity needs for the transitioning of battery management systems from first to second life.}, language = {en} } @article{BluemkeHof2023, author = {Bl{\"u}mke, Julian and Hof, Hans-Joachim}, title = {Binding the Battery to the Pass: An Approach to Trustworthy Product Life Cycle Data by Using Certificates Based on PUFs}, volume = {16}, journal = {International Journal on Advances in Security}, number = {1\&2}, publisher = {IARIA}, address = {[s. l.]}, issn = {1942-2636}, url = {http://www.iariajournals.org/security/tocv16n12.html}, pages = {44 -- 53}, year = {2023}, language = {en} } @inproceedings{BluemkeLavesHof2025, author = {Bl{\"u}mke, Julian and Laves, Claudius and Hof, Hans-Joachim}, title = {Identifying Building Blocks for Second-Life-Enabled Battery Management Systems}, booktitle = {Conference Proceedings: 2025 IEEE International Conference on Environment and Electrical Engineering and 2025 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I\&CPS Europe), 15-18 July 2025, Chania, Crete - Greece}, editor = {Leonowicz, Zbigniew and Stracqualursi, Erika and Jasinski, Michal}, publisher = {IEEE}, address = {Piscataway}, isbn = {979-8-3315-9515-9}, doi = {https://doi.org/10.1109/EEEIC/ICPSEurope64998.2025.11169196}, year = {2025}, language = {en} } @inproceedings{BluemkeHof2022, author = {Bl{\"u}mke, Julian and Hof, Hans-Joachim}, title = {Authentic Batteries: A Concept for a Battery Pass Based on PUF-enabled Certificates}, booktitle = {SECURWARE 2022: The Sixteenth International Conference on Emerging Security Information, Systems and Technologies}, editor = {Yee, George}, publisher = {IARIA}, address = {[s. l.]}, isbn = {978-1-68558-007-0}, url = {https://www.thinkmind.org/index.php?view=article\&articleid=securware_2022_1_120_30051}, pages = {76 -- 81}, year = {2022}, language = {en} }
