In September 2025, DENSO and TÜV Rheinland Japan signed a Memorandum of Understanding to advertise Digital Product Passports, leveraging their mixed experience to develop the white paper. This doc is meant to help financial operators, together with automotive and battery producers, in understanding the necessities for compliance with the EU Battery Regulation.
The white paper provides an outline of world developments associated to Battery Passports and descriptions key regulatory necessities underneath the EU Battery Regulation and the Ecodesign Regulation. It addresses knowledge definitions and IT structure necessities essential for compliance.
DENSO and TÜV Rheinland Japan goal to foster a typical understanding of Battery Passport implementation via this white paper, offering insights into regulatory developments, standardization efforts, data-space interoperability, and sensible implementation challenges. The doc serves as a useful resource for companies chargeable for Battery Passport compliance and people required to offer associated knowledge.
The detailed specs and standardization actions for Battery Passports are anticipated to evolve over the approaching years. The white paper is out there upon request, topic to evaluation of the offered data.
