DENSO Corporation and TÜV Rheinland Japan have successfully validated a battery passport for an energy storage product from AESC Group Ltd., marking a significant step towards compliance with the upcoming EU Battery Regulation.
The joint validation used actual data from AESC's Energy Storage System (ESS) business to ensure the product's adherence to the EU Battery Regulation, which will mandate battery passports from February 2027. DENSO provided the technological foundation for the battery passport, while TÜV Rheinland Japan acted as the independent third-party certification body.
Under the EU Battery Regulation, companies must prepare data derived from actual sources, operate necessary systems, and ensure practicality and feasibility, including third-party verification. The regulation aims to promote sustainable battery products as part of Europe's transition to a circular economy.
The partnership between DENSO and TÜV Rheinland Japan began with a memorandum of understanding in September 2025, focusing on advancing the Digital Product Passport. The validation process confirmed that DENSO's battery passport service not only meets regulatory requirements but also offers a practical solution for integration into business processes.
AESC, as the data provider, prepared the necessary compliance data and implemented sustainability measures across its value chain. The company aims to support a closed-loop circular economy framework for battery recycling and reuse, aligning with the EU's sustainability goals.
Through this validation, DENSO and TÜV Rheinland Japan identified challenges associated with the EU Battery Regulation's requirements and verified the battery passport's effectiveness in ensuring regulatory compliance and data reliability.
Following the successful validation, the companies plan to expand their efforts to include automotive traction batteries and further advance the practical implementation of battery passports across a broader range of applications.
These initiatives aim to enhance regulatory compliance not only in Europe but also in global markets, contributing to resource circulation and supporting the realization of a sustainable society.
