EU Batteries Regulation (Regulation (EU) 2023/1542) Batteries Regulation and ESPR

Both the Batteries Regulation and ESPR are built around persistent product data, access control, traceable updates, and machine readable exchange. For the battery passport, Article 78 already requires open standards, structured and searchable data, and an open interoperable data exchange network without vendor lock in.

That means the core technical services can and should be shared: identifier resolution, schema management, access rights, logging, and long term persistence.

The battery passport is more than a generic product passport. Annex XIII defines battery model fields, restricted fields for persons with a legitimate interest, authority only test report fields, and individual battery fields such as state of health, status, cycles, accidents, and operating conditions.

The battery passport also has battery specific lifecycle rules. A repurposed or remanufactured battery needs a new passport linked to the original passport, and the passport ceases to exist after recycling.

Build one passport platform with a reusable core and product specific schema modules. The core should handle identifier issuance, QR resolution, authentication and authorization, schema versioning, audit logging, and availability. The battery module should implement Annex XIII fields, Article 77 access tiers, and lifecycle update logic.

This avoids the common failure mode where a battery team builds a narrow portal that later cannot satisfy ESPR interoperability expectations or support another product passport category.

The practical rollout is battery first but architecture aware. Start with the battery categories that will need passports from 18 February 2027. Use those early models to harden the resolver, access model, data validation, and supplier onboarding process, then generalize those services for future DPP obligations.

This creates a stronger investment case and avoids rebuilding the same infrastructure twice.
