Challenges
- Lack of standardized and trustworthy verification for battery pass data in the Catena-X ecosystem
- Difficulty in securely linking battery data to digital twins and validating them transparently
- Need to assess the feasibility of a secure and scalable architecture for digital signing and authentication of data
Solution
- As part of the technical PoC, TÜV SÜD developed a demo such as Catena-X-compliant certificates for battery pass data that can be digitally signed and verified
- Use of verifiable credentials to test the authenticity and integrity of the certificates in accordance with W3C standards
- T-Systems supported the use case development and ideation with a workshop to analyze feasibility and identify potential challenges at an early stage
Benefits
- The PoC has shown that standardized and automated verification of battery pass data is technically feasible
- The results provide valuable insights for potential further development and scaling in the Catena-X ecosystem
- Thanks to the close cooperation between TÜV SÜD and T-Systems, an initial concept for a possible future solution was developed that supports regulatory requirements and sustainability goals
TÜV SÜD is a leading global provider of safety and sustainability solutions, offering comprehensive testing, inspection, certification and consulting services to add value and inspire confidence across all industries.
T-Systems provided the Build & Operate environment (Catena-X Sandbox) that enables TÜV SÜD to research and develop innovative solutions for more value and more trust in battery passports from the Catena-X network. This partnership helped TÜV SÜD to identify concrete approaches and business value for its ecosystem partners.
