What Happened
DENSO CORPORATION has launched the DENSO Digital Product Passport Solution for Battery, a battery passport service designed to help automakers, battery manufacturers, and other businesses comply with the European Battery Regulation and improve battery traceability. The service generates battery passports for individual battery products, based on a data model developed by the Battery Pass-Ready consortium in Europe. Businesses can use the service to collect battery-related information from their enterprise systems and suppliers, while end users can access the information by scanning QR codes attached to products.

DENSO launches the battery passport service
Battery passports become mandatory for EV, LMT, industrial, and other batteries
- Generates battery passports for individual battery products using the Battery Pass-Ready data model
- Collects battery information from enterprise systems and suppliers
- Lets end users scan QR codes on products to access battery information
- Manages information visibility by user type, such as consumers and economic operators
- Uses blockchain technology to create tamper-resistant records
The service includes access control functionality that adjusts information visibility based on the type of user, such as consumers and economic operators, helping organizations achieve regulatory compliance and secure data management while respecting data sovereignty. DENSO has been researching and developing blockchain technologies since 2017. By managing records in a chained structure, any modification to a record would create inconsistencies with related records, making the system theoretically resistant to tampering and helping ensure the reliability of data required for battery passports.
Looking ahead, DENSO plans to expand the service beyond battery passports to support other Digital Product Passports required under the Ecodesign for Sustainable Products Regulation (ESPR). The service adopts a multi-connectable architecture that can interface with multiple data platforms, enabling future expansion to a wider range of product categories beyond batteries. DENSO says it will continue to support regulatory compliance not only in Europe but also across global markets.
Previously from Denso
DENSO has been preparing for the EU Battery Regulation with TÜV Rheinland Japan. In June 2026, the partners jointly validated a battery passport for AESC's energy storage system, confirming compliance with the upcoming EU Battery Regulation. In August 2026, they published a technical white paper explaining the EU Battery Passport rules that take effect in February 2027.

Why this matters
The European Battery Regulation will require battery passports for EV, light transport, industrial, and other batteries starting in February 2027, so automakers and battery manufacturers must track detailed product data. DENSO's new service gives them a way to generate compliant passports and control who sees the data. It also signals a broader move toward digital product passports for many products under EU rules.
