SeBaPaD 2: Secure Battery Passport Demonstrator 2

SeBaPaD 2 addresses the research challenges that arise when scaling a secure Battery Passport and Battery Management System from module level to a high-voltage battery pack.

The project investigates how battery condition and performance assessment, data aggregation, and security concepts can be preserved when multiple modules are combined into a pack operating at approximately 500 V. This requires research into pack-level system architectures, coordination between module-level and pack-level BMS functions, and consistent aggregation of lifecycle data into a single pack-level Battery Passport.

Security is addressed as a system property. By analyzing how increased system complexity affects data integrity and trust, the project explores how secure hardware elements, protected communication, and software-based checks can be combined to maintain trustworthy Battery Passport data at pack level.

System integration and experimental validation are performed at the battery prototyping and testing facilities of TNO in Helmond, enabling controlled testing of high-voltage packs and BMS behaviour under realistic conditions.

SeBaPaD 2 is a collaboration between TNO and NXP, building on a proven partnership established in SeBaPaD 1.

TNO contributes expertise in battery systems engineering, Battery Management System algorithms, system integration, testing, and the Battery Passport cloud infrastructure. NXP provides Battery Management System hardware platforms, embedded software, and security technologies that are essential for high-voltage battery systems.

By combining complementary expertise, the partners aim to deliver a realistic and scalable reference implementation that reflects both research insights and industrial constraints.
