DPP Hero: DIN SPEC 99100 Battery Passports

I built DPP Hero around a simple constraint: battery passport creation shouldn’t require an IT project just to get to a publishable Digital Product Passport.

DIN SPEC 99100 has a specific data structure, and the work isn’t just “collect fields”—it’s making sure master data, materials, CO₂ footprint, due diligence, circularity, performance, and labeling are captured in the right order and can be exported for documentation.

The result is a guided 7-step workflow where manufacturers, importers, and distributors can capture required data and then publish a passport for each product with a QR code and a public product page.

Instead of forcing suppliers to build their own portals, DPP Hero uses share-links so suppliers can enter their data without an account. That keeps the process self-service while still being traceable.

I also focused on standards alignment (DIN SPEC 99100, BatteryPass Data Model, GS1 Digital Link, JSON-LD) so the outputs are not just “human readable,” but also usable for downstream compliance and audit needs.

Finally, because regulation timelines matter for operators, DPP Hero is designed to help prepare for the EU Battery Regulation that becomes mandatory from February 2027. The workflow, exports, and publishing steps are built to support that kind of operational ramp-up.

As of 2026, DPP Hero is available with a free tier and paid plans that scale by product volume, so teams can start without committing to a full implementation.

Battery passport requirements are not just a single document. They’re a structured set of data clusters that must be captured, validated, and then published as a Digital Product Passport.

Teams often underestimate the “data plumbing” work: master data needs to connect to materials and chemistry details; CO₂ footprint needs to be aligned with lifecycle phases; due diligence must be documented in a way that can stand up to audits.

Even when companies already have ERP fields, mapping them into the DIN SPEC 99100 structure can become a project. That’s where manual spreadsheets and internal workflows tend to break down—especially when suppliers must contribute their own inputs.

Supplier onboarding is another bottleneck. If suppliers have to create accounts or follow complex processes, you lose time and you increase the chance of inconsistent data entry.

Finally, compliance work has to produce artifacts you can actually use: exports for audits and documentation, and a published passport that includes a QR code and a stable public product page.

For EU operators, the timing matters. The EU Battery Regulation is mandatory from February 2027, so teams need a workflow that supports ongoing data capture and publication rather than a one-time scramble.

DPP Hero addresses these problems by turning the DIN SPEC 99100 data structure into a guided workflow, with outputs that are designed for publishing and documentation—not just internal notes.

DPP Hero is self-service software for creating digital battery passports based on DIN SPEC 99100. Manufacturers, importers, and distributors capture all required product data in a guided 7-step workflow and publish a Digital Product Passport without IT projects.

The workflow covers the full set of DIN SPEC 99100 data clusters: identification, materials, CO₂ footprint, due diligence, circularity, performance, and labeling. Each step is structured so you can move from drafting to publishing without losing context.

Once the data is captured, DPP Hero generates QR codes and public product pages for each published product, so your supply chain can reference the passport consistently.

To involve suppliers efficiently, DPP Hero provides share-links so suppliers can enter their data without having an account of their own.

For teams that need system-level workflows, DPP Hero supports ERP integration and bulk import through a REST API and CSV import. That means you can onboard product data at scale rather than retyping it manually.

For documentation and audit trails, DPP Hero offers JSON and PDF export, aligning with standards such as JSON-LD for standards-based outputs.

Operational risk is reduced with EU hosting (Frankfurt, eu-central-1) and GDPR-compliant handling.

DPP Hero is available in German, English, and 中文, which helps multi-region teams and suppliers collaborate in the language they use day-to-day.
