DENSO CORPORATION (Headquarters: Kariya City, Aichi Prefecture; President: Shinnosuke Hayashi, hereinafter described as “DENSO”) and TÜV Rheinland Japan, Ltd. (Headquarters: Yokohama City, Kanagawa Prefecture; President: Kunihiro Okamoto, hereinafter described as “TÜV Rheinland Japan”) have actually carried out a joint recognition of battery passport for an energy storage item of AESC Group Ltd. (Head Office: Yokohama, Kanagawa; CEO: David Wan; hereinafter “AESC”), utilizing real information from AESC’s ESS * 1 organization. In this recognition, DENSO, in partnership with the appropriate celebrations, was accountable for structure and offering the technological structure for battery passport, and TÜV Rheinland Japan, as the independent third-party accreditation body, have actually validated that the item abides by the EU Battery Regulation * 2 and is both useful and possible for real-world usage. This accomplishment lays a strong structure for AESC’s energy storage items to get in the EU market.
– Challenges and Background
Recently, social expectations have actually progressively required accomplishing carbon neutrality and transitioning to a circular economy that allows resources to flow within the financial system. As an outcome, efforts to establish sustainable items have actually sped up. In Europe in specific, Digital Product Passport (DPP)* 3 is being presented to digitally handle and present item traceability info. Under the EU Battery Regulation, a battery passport will end up being necessary from February 2027 for batteries utilized in vehicle, commercial, and other applications.
At the very same time, essential obstacles in resolving the Regulation consist of preparing information originated from real information, running the needed systems, and making sure general functionality and expediency, consisting of third-party confirmation.
– Overview of the Validation
Versus this background, DENSO and TÜV Rheinland Japan got in a memorandum of understanding in September 2025 to advance the Digital Product Passport * 4. Under this collaboration, the 2 business carried out a recognition of a battery passport utilizing real information from AESC’s ESS batteries for the European market, with AESC functioning as the information supplier, to confirm the functionality and regulative compliance of battery passport under the EU Battery Regulation.
DENSO supplied a service to support the generation and management of battery passport in accordance with the EU Battery Regulation. Based upon requirements developed by the Battery Pass Consortium * 5, the service creates a battery passport for each item and makes it possible for access to battery info through a QR code attached to the item. The service likewise consists of an access-rights management function that manages details readily available for seeing depending upon the user’s function, guaranteeing information security while appreciating the information sovereignty of each stakeholder and supporting regulative compliance.
As maker of energy storage items, AESC prepared the required information for compliance with the upcoming battery passport required and offered information from its existing ESS service, while taking into consideration future exports to Europe and consumer requirements.In preparation for complete compliance with the upcoming battery passport required, AESC has actually carried out extensive sustainability and compliance steps throughout its worth chain, extending beyond the particular information scope of this recognition. The business releases organized supply chain oversight to impose certified practices and strenuous quality assurance. To support long-lasting sustainability, AESC has actually estSSablished, through making use of digital battery passport options, a closed-loop circular economy structure for battery recycling and reuse.
As a third-party accreditation body, TÜV Rheinland Japan confirmed the information managed by the battery passport service based upon the EU Battery Regulation and requirements such as DIN DKE SPEC 99100 * 6.
– Results of the Validation
Through recognition utilizing real information, the business recognized the information preparation and functional difficulties connected with the EU Battery Regulation’s requirements in a real-world organization environment. The recognition likewise validated that DENSO’s battery passport service extends beyond conference official regulative requirements and represents an extremely useful option that can be incorporated into real-world company procedures. In addition, the confirmation carried out by TÜV Rheinland Japan, as a third-party accreditation body, confirmed that the battery passport works in both regulative compliance and information dependability.
Based upon this recognition utilizing ESS battery information, DENSO and TÜV Rheinland Japan will broaden their efforts to consist of AESC’s vehicle traction batteries and collectively advance the useful execution of battery passport throughout a more comprehensive series of applications. Through these efforts, they will advance regulative compliance not just in Europe however likewise in worldwide markets, assistance worth development for consumers such as car manufacturers through resource flow and add to the awareness of a sustainable society.
