What does the EU digital battery passport require from 18 February 2027?

A QR-linked electronic record under Regulation (EU) 2023/1542 for EV, LMT and industrial batteries above 2 kWh, with lifecycle, carbon, material, circularity and performance data structured per the guidance data points by category and the DPP technical framework.

How many data fields does a battery passport contain?

Around 80 mandatory attributes for EV batteries, organized in seven clusters. Many composition and carbon fields are not to be filled as of February 2027, while performance, dismantling and state-of-health fields are mandatory.

What is the battery passport foundation before the QR?

Product, site, supplier and transactional data connected for mapping, raw material traceability, product-level carbon calculation, completeness monitoring and tiered QR and API access.

Does Hoken Pass replace Carbmee EIS?

No. Carbmee EIS builds the enterprise data foundation for carbon and supplier workflows. Hoken Pass validates the resulting battery data, flags gaps, generates the structured battery passport with JSON-LD and GS1 Digital Link, hosts it versioned, and adds a qualified eIDAS timestamp and blockchain anchor for audit.
