DENSO and TÜV Rheinland Japan Validate Battery Passport for AESC

In a significant advancement for energy storage solutions, DENSO CORPORATION and TÜV Rheinland Japan have announced the successful validation of the Battery Passport for an energy storage product developed by AESC Group Ltd. This collaboration marks an important step in ensuring compliance with the upcoming EU Battery Regulation, which aims to enhance sustainability and accountability in the battery market.

Background of the Initiative

In recent years, global attention on carbon neutrality and the transition towards a circular economy has intensified. With the implementation of the EU Battery Regulation approaching in February 2027, a digital tool known as the Digital Product Passport (DPP) is being introduced to manage the traceability of products digitally. This digital passport will offer crucial information regarding production, materials used, recyclability, and more.

To tackle the complexities associated with this regulation, DENSO and TÜV Rheinland Japan signed a memorandum of understanding in September 2025 to develop the DPP. Using real-time data from AESC’s energy storage system (ESS), the companies aimed to verify the practicality and compliance of the Battery Passport under real-world conditions.

The Validation Process

DENSO's role was integral in creating and establishing the technological foundation necessary for the Battery Passport. TÜV Rheinland Japan, acting as an independent certifying body, verified that the product adheres to the EU Battery Regulation, ensuring it is both practical and suitable for real-world use. This partnership has enabled a thorough validation process that relies on actual operational data, pinpointing challenges associated with data preparation, system operations, and regulatory compliance.

AESC, responsible for supplying the necessary data, prepared for the Battery Passport initiative by implementing extensive sustainability measures throughout its supply chain. Their efforts extend beyond the immediate scope of this validation and include systematic monitoring to ensure compliance and quality control within operations.

Results of the Validation

The validation has been groundbreaking, leading to the identification of challenges in data management and operational efficiency related to the EU Battery Regulation. The results showed that DENSO’s Battery Passport Service surpasses mere regulatory compliance, offering a comprehensive solution that can be seamlessly integrated into existing business processes.

TÜV Rheinland Japan has confirmed that DENSO's service is effective in maintaining compliance and ensuring data reliability. The findings highlight the service's capacity to align with strict regulations while promoting transparency and accountability in data management.

With the conclusion of this validation, both DENSO and TÜV Rheinland Japan are poised to broaden their efforts to include AESC’s drive batteries, facilitating the Battery Passport's implementation across a wider range of applications. This initiative supports not only compliance within European markets but also strengthens the global positioning of energy storage solutions, thereby contributing to a sustainable society and a thriving resource circular economy.

Conclusion

The collaboration between DENSO, TÜV Rheinland Japan, and AESC represents a crucial milestone in the realm of sustainable energy solutions. As markets shift towards enhanced transparency and compliance, the Battery Passport will play an instrumental role in guiding the energy storage industry toward a responsible future, fulfilling both consumer expectations and regulatory demands.
