DENSO and TÜV Rheinland Japan Validate Battery Passport Viability

DENSO Corporation, headquartered in Kariya, Japan, alongside TÜV Rheinland Japan, has recently conducted a significant validation confirming the viability of the Battery Passport for AESC Group's energy storage products. This collaborative effort utilizes real business data from AESC's Energy Storage Systems (ESS). The validation aims to ensure compliance with the European Battery Regulation, paving the way for AESC products to enter the EU market effectively.

Background and Challenges

In recent years, the social demand for carbon neutrality and a transition towards a circular economy has intensified. This shift has pushed for accelerated development of sustainable products. Particularly in Europe, the implementation of the Digital Product Passport (DPP) is gaining momentum, aimed at managing and presenting product traceability digitally. Starting February 2027, the Battery Passport will be obligatory for batteries utilized in automotive and industrial applications under the EU Battery Regulation.

However, several challenges arise with this regulation. Companies face hurdles in preparing data derived from actual performance, operating necessary systems, and affirming overall viability and practicality, which includes third-party verification.

Summary of Validation Effort

In light of these factors, DENSO and TÜV Rheinland Japan initiated a Memorandum of Understanding in September 2025 to propel the Digital Product Passport development. This partnership enabled them to validate a Battery Passport using real performance data from AESC for the European market, ensuring compliance with the EU Battery Regulation.

DENSO was responsible for creating and supporting the technological foundation for the Battery Passport while TÜV Rheinland Japan verified the product's compliance as an independent third-party certification body. The process included generating a unique passport for each product, accessible through a QR code affixed to the product, which allows users to view battery information securely while controlling data accessibility based on user roles. This maintains data sovereignty for stakeholders and ensures regulatory compliance.

AESC, as a manufacturer of energy storage products, compiled the essential data necessary to meet forthcoming regulatory requirements regarding Battery Passports, considering future exports to Europe and addressing customer needs. They have also adopted comprehensive sustainability measures and compliance protocols across their value chain, with a systematic monitoring approach to guarantee adherence to standards and stringent quality control.

Validation Results

The validation exercise revealed operational and data preparation challenges related to the EU Battery Regulation within a real business context. Additionally, the results demonstrated that DENSO's Battery Passport service exceeds formal regulatory requirements, representing a practical solution that can be seamlessly integrated into actual business operations.

Moreover, TÜV Rheinland Japan's independent verification confirmed both regulatory compliance and data reliability of the Battery Passport. Building on this validation, DENSO and TÜV Rheinland Japan intend to extend their focus to include AESC's traction batteries for automotive applications and advocate for the practical implementation of the Battery Passport across a broader range of uses.

Through these initiatives, they aim to enhance regulatory compliance not just in Europe but globally, creating value for clients such as automotive manufacturers by facilitating resource circulation and contributing to a sustainable society. The validation of the Battery Passport serves as a stepping stone in redefining product management in the new era of energy storage solutions, promoting both innovation and ecological responsibility.

Conclusion

In conclusion, the collaborative work between DENSO, TÜV Rheinland Japan, and AESC highlights the pivotal role of innovative technologies in meeting regulatory demands while ensuring sustainable practices. As the industry moves towards a future where sustainability is paramount, initiatives like the Battery Passport will undoubtedly play a crucial role in shaping energy storage solutions that align with global environmental objectives.
