Challenge
EU Battery Regulation and complex EV supply chains
A European car manufacturer produces its full range of electric vehicles in Europe and China. With all its batteries produced by a key supplier in China, the company faces a significant challenge. The new EU Battery Regulation requires a Digital Battery Passport for all EV batteries placed on the European market, which must include data on materials, carbon footprint, and a verified due diligence report. Their existing, fragmented system of spreadsheets and emails can’t handle the data volume or the strict chain-of-custody requirements, risking market access and brand reputation.
Solution
A secure, scalable platform for Battery Passport traceability
The manufacturer partnered with Kezzler to implement a scalable, compliance-ready solution:
- Cell-to-pack digital ID: Unique identifiers assigned at cell and pack level, ensuring traceability throughout the supply chain.
- Granular traceability: Ability to trace underperforming cells back to exact batches, raw materials and suppliers – paving the way for future circular repair and reuse.
- Seamless system integration: Kezzler’s platform connects with supplier systems to structure data on provenance, carbon footprint and performance.
- Compliant battery passport EU: Automatically generated, QR-accessible passports aligned with battery passport regulation requirements.
Results
Transforming compliance into strategic value
Kezzler’s solution delivered clear, tangible benefits:
- Regulatory compliance: The car manufacturer ensures seamless market access in Europe by meeting all mandatory DBP requirements.
- Enhanced brand trust: The DBP provides transparent, verifiable data, allowing the company to prove its sustainability claims and build trust with eco-conscious consumers.
- Supply chain resilience: The car manufacturer gains granular, real-time visibility into its supply chain, helping to mitigate risks, optimize logistics, and reduce the chance of disruption.
