SaaS platform for digital product passports – built directly on the requirements of the EU Battery Regulation and audit-ready from day one

Our challenge

Under the EU Battery Regulation (EU 2023/1542), batteries placed on the European market must carry a digital battery passport from February 2027 – a structured dataset covering everything from material composition and carbon footprint to due diligence and recycling.

For manufacturers, importers, and distributors, the challenge is concrete: the information is scattered across spreadsheets, ERP systems, and suppliers – and generic documentation tools don't match the fields the EU actually requires.

Syntakk – a compliance startup from Odense – wanted to build a platform structured directly around the regulation. Not customized templates, but fields, validation, and compliance status that follow EU 2023/1542 exactly as written.

Our task: to design and develop the core of the platform – where companies create, manage, and share digital product passports, audit-ready from day one.

Our approach

We started by immersing ourselves in the Battery Regulation. The requirements of EU 2023/1542 were translated into concrete data fields in the platform – from battery chemistry and critical raw materials to recycled content, carbon footprint, certifications, and due diligence. The regulation's own requirements and thresholds are built into the fields as guidance, so users are never in doubt about what to fill in, or why.

The entire platform is built around a single shared data model. It ensures that the editing tool and the finished product passport always stay in step, and that new templates can be added without rebuilding the platform.

The business logic – compliance calculation, version history, and change tracking – was developed test-driven, so the rules can be verified and extended without errors.

Finally, the user interface and the backend are kept cleanly separated, making the platform robust in operation and easy to develop further.

The solution

In Syntakk, companies create their digital product passport from a ready-made template covering the Battery Regulation's requirements end to end: product identification, technical specifications, material composition with the EU's list of critical raw materials, carbon footprint, certifications, supply chain and due diligence – all the way to recycling.

Fields automatically validate the information entered – GTIN and EAN numbers, for example – and every field comes pre-marked as public or protected. Syntakk has defined these access levels based on the regulation's requirements, so companies never have to work out which data the entire value chain may see, and which is reserved for authorities and selected partners.

Along the way, the platform shows an overall compliance status, making it clear how far the battery passport is from meeting the requirements. When a passport is published, a locked version with a full change history is stored, so the company can always document what was published, and when. That is exactly what matters in an audit.

Every product passport gets its own web address and QR code, ready to be placed on the battery and shared with the entire value chain.

The user interface is built in Vue.js with Tailwind CSS and shadcn-vue, while a Laravel-based backend forms the foundation of the platform.

Our conclusion

Together with Syntakk, we have built a SaaS platform that turns one of the EU's most complex regulations into something companies can work with every day: battery companies create, manage, and share digital product passports that follow the Battery Regulation from the very first field – without having to interpret the legal text themselves.

For Syntakk, the platform turns their business idea into reality. They can now take on battery companies as customers and guide them all the way to compliance – with templates Syntakk has defined from the regulation's requirements, instead of manual documents and spreadsheets.

The platform is also built to grow. Because everything rests on a single shared foundation, new templates and industries can be added as the EU's upcoming ESPR requirements extend digital product passports to far more product categories – without rebuilding anything.

The result is a thoroughly tested platform that runs solidly in production – ready to grow with both the customers and the legislation.
