Create a battery passport
in 7 guided steps

The path to your first passport in practice

With DPP Hero, a battery passport is created entirely in the browser: you set up an account, choose the battery type and work through the seven steps of the guided editor until the publish gate gives the green light. This page describes the path as it actually looks inside your account. For the legal side, meaning who needs a passport and from when, see Battery Passport: When Is It Mandatory?

Create an account and choose your battery type

Getting started is self-service: create an account, confirm your email, create your first passport. Then you choose one of five battery types: EV, LMT, industrial, stationary energy storage or battery without BMS. This choice is more than a heading, because the field registry shows the mandatory and visible fields that match each type. A passport for a stationary energy storage system asks for different information than one for an e-bike, and you only see what counts for your type.

The seven steps in the editor

The structure follows DIN SPEC 99100 with its seven data categories: identification, materials, carbon footprint, due diligence, circularity, performance and durability, and labeling. Every field is explained, you do not interpret a specification and you do not map attributes by hand. Whatever you do not know yet can stay open for now: the passport remains a draft for as long as you need it to.

Where an open legal question sits behind a step, the editor shows the current status. Take the carbon footprint: the related obligations have not been triggered yet because the EU's methodology and format legal acts are still missing. You can nevertheless capture the values from your life cycle assessment in structured form today and keep them when the legal acts arrive.

Publish gate, publication and QR code

Publication only happens once the passport is complete. The publish gate checks your organization's mandatory data, the completeness of all seven steps and your GS1 identifiers, including the GTIN check digit and the GLN of the production site. On top of that, a blocking schema validation runs against the Battery Passport Data Model v1.3: whatever the schema does not accept does not go live.

After publishing, the passport exists as a public page, with no login and no cost for the viewer. The address is a GS1 Digital Link, you download the QR code as SVG or PNG, and for series as a ZIP with up to 500 codes. Every published version is signed and versioned, a public verify endpoint recalculates hash and signature live, and the page Battery Passport Software gives an overview of all features. The direct way there: set up an account and start with step 1.

What data you need and where it comes from

The editor is the easy part. What matters is what you feed into it. In practice, three sources cover almost everything: your own company, your suppliers and your GS1 licenses. To tick things off before you start, there is the Battery Passport Checklist

From your own company

Master data, model names and production sites usually live in your ERP or in your data sheets. Performance and durability values such as capacity, voltage, cycle life and temperature ranges are in the technical data sheet. The EU declaration of conformity is something you create and are responsible for yourself; in the passport it is stored as a document. For the carbon footprint step you need your life cycle assessment, for due diligence the report along with its evidence.

From suppliers via share link

Cell chemistry, raw material shares and recycled content rates are often known only to the cell manufacturer. That is what share links are for: you release a single section, the supplier enters their values directly without a login of their own, and restricted values appear to them only as a status, not in plain text. This spares you the usual Excel round by email. If you bring batteries into the EU as an importer, you collect the manufacturer's information the same way.

GS1 identifiers with lead time

For publication, DPP Hero checks your GS1 identifiers, including the GTIN check digit and the GLN of the production site. You do not assign these identifiers yourself, they come from your GS1 licenses. Which license your company needs is something to clarify directly with GS1, and early: applying for it is the one part of the path that no software can speed up. In parallel, your draft can already grow in the editor, the GS1 check only applies when you publish.

What takes time and what does not

The honest answer: it is not the editor that takes time, it is gathering the data. Once the data sheet, life cycle assessment, due diligence report and identifiers are in place, filling in the seven steps is focused work in one sitting, not a project. Auto-save keeps every intermediate state, and a draft can sit as long as needed and grows as soon as new documents arrive.

What does take time are the things outside the editor: an LCA study if none exists yet, answers from cell manufacturers, the internal sign-off of the declaration of conformity and the lead time for GS1 identifiers. These items depend on third parties and internal processes, not on the software. That is exactly why it pays to create the draft early and make the gaps visible instead of waiting for a complete folder: the half-finished passport shows you which requests you need to send today.

Installation and IT, on the other hand, are not a time factor. DPP Hero runs in the browser, with no setup project and no coordination rounds. If you want to create many passports from existing data, you use the CSV import or the REST API aligned with EN 18222; for your first passport you need neither. The 18 February 2027 deadline sounds far away, but the procurement loops with suppliers cannot be compressed. The earlier the first draft exists, the calmer the rest of the path becomes.

Five typical beginner mistakes

These five patterns regularly cost time on a first battery passport, and all five are avoidable:

1. Applying for GS1 identifiers too late Publication checks GS1 identifiers such as the GTIN check digit and the GLN of the production site, and both come from licenses with their own application process. If you sort this out only at the end, you have a finished draft and still have to wait. Clarify early with GS1 which license your company needs.
2. Planning the passport as a PDF collection A battery passport is a structured data set, not a document archive. If you collect values in PDFs and spreadsheets first, you end up retyping them into fields later anyway. Better to capture them directly in the editor; documents such as the declaration of conformity go in as attachments at the place provided for them.
3. Collecting supplier data by email Excel attachments create competing versions, follow-up questions and transcription errors. Share links release exactly one section to the supplier, without a login, and their values land in the right field of the passport with no detour.
4. Waiting for the open CO₂ legal acts The fact that the methodology and format acts for the carbon footprint are still missing does not move the 18 February 2027 deadline. The other categories are independent of this, and a passport can be created and published in full today.
5. Confusing the registry with the passport The EU registry is a directory, it does not replace the passport. Battery registration is still locked there on the EU side, and later only an eIDAS-verified economic operator may register. That verification needs lead time too.

What the EU registry can already do today and what it cannot is covered in EU Battery Passport Registry. The common thread: start everything that depends on third parties early and let the draft grow in the editor in parallel.

Costs and getting started

The first battery passport is free forever, with all core features: seven guided steps, publish gate, public passport page, QR code and exports. You do not need payment details to start, and there are no consulting or onboarding appointments. DPP Hero is self-service, from account to publication.

Paid plans start at EUR49 per month and grow with the number of your passports. All prices and features are listed transparently on the pricing page; for a view of the total costs, including items outside the software such as an LCA study or GS1 licenses, see Battery Passport Costs

Your data stays your data: JSON per Battery Passport Data Model v1.3, DIN SPEC JSON and PDF in German and English can be exported at any time, so no lock-in arises. If you want to cover the basics before you start, the overview What Is a Battery Passport? and the Battery Passport topic page bundle the context. This page here remains the direct way into the editor: create an account, choose your type, create your first passport.
