Seamlessly integrate battery pass

The integrable battery passport: SecIdent adapts to production, not the other way around.

The EU Battery Regulation (EU) 2023/1542 requires manufacturers to provide a digital battery passport for many types of batteries. This must contain technical, environmental, and manufacturing data in a standardized format and be published via the central EC Registry. For many manufacturers, the greatest effort involved is not in the software, but in obtaining the data from production and the supply chain.

SecIdent does not aim to restructure processes, but rather to integrate seamlessly into existing workflows. After all, a battery passport should not dictate production—the software must reflect the reality of production.

Digital IDs have been our core business for over a decade.

SecIdent was not created as a “battery passport tool,” but has been providing digital identities and serialization solutions for regulated markets for more than ten years. Take the pharmaceutical sector, for example: precise serialization is mandatory under the EU Falsified Medicines Directive. We have been integrating this into complex production lines, printing processes, testing facilities, and ERP/MES systems for years.

This experience is an advantage in the context of battery passports: production facilities often work with tight cycle times, heterogeneous machine parks, and historically grown IT landscapes. A new regulatory requirement must fit into this environment, not the other way around. SecIdent is designed to do just that.

At Battery Manufacturing Day 2025 in Karlsruhe, we presented a live demonstration of how battery passports can be implemented in production.

Collect, enrich, publish data—fully automated

SecIdent queries all necessary attributes, imports data from supply chain, manufacturing, and testing systems, and automatically publishes completed battery passport data records to the EC Registry. Companies retain control at all times via the admin interface: roles and rights, approvals, verification processes, and monitoring can be controlled centrally.

At the same time, SecIdent provides QR codes and unique identifiers and outputs battery passport data in the required formats for each stakeholder – from market surveillance authorities to service partners to end users.

Attribution follows the manufacturing logic

Each battery passport consists of a set of attributes. Much of the information never changes or changes only rarely. SecIdent makes consistent use of meaningful structures: information recorded at the type or batch level does not need to be retransmitted for each battery on the line. Individual batteries often have only a few variable values, such as state of health or test results.

This reduces integration effort, minimizes sources of error, and significantly speeds up implementation.

Flexible battery pass IDs – tailored to production realities

Manufacturers work in very different ways. SecIdent opens up several ways to provide IDs for the battery passport.

  • Maximum automation: Automatic, with the start of a production order – ideal for clearly structured production runs.
  • Maximum robustness: From a larger ID pool – useful for variable quantities or multiple lines.
  • Easiest integration: Transfer of existing serial numbers at the end of production – provided they meet regulatory requirements.

All three variants are fully API-enabled, traceable, and auditable.

Every production environment is different. As part of the onboarding process or our no-obligation battery passport starter package, we work with the customer to analyze existing processes, data flows, and manufacturing conditions. This results in a technical implementation that is robust, quick to integrate, and low-maintenance in the long term—ideally without the need for costly modifications or additional manual steps.

The goal is always the same: if a manufacturer is already making a great effort to collect all the relevant data for the battery passport, then the technical implementation must be as smooth as possible.
