Battery Passport Costs: Full Breakdown

The 5 Cost Factors at a Glance

The cost of a battery passport cannot be stated as a flat figure. It depends on battery type, production volume, existing data infrastructure, and the chosen implementation approach. One thing is clear, however: investing in a compliant battery passport is significantly less costly than the consequences of non-compliance.

These five cost factors determine the total effort:

Cost Factor 1: Data Collection

The largest cost block is almost always the initial data collection. DIN SPEC 99100 structures the battery passport into seven data categories. How many of those fields are mandatory depends on the battery type: the Commission guidance “Digital Batteries Passport, data points by category” of 28 July 2026 lists 71 data points and classifies each one individually as mandatory, optional, applicable only in specific cases, or not to be filled in for now.

The challenge: this data rarely exists in one central place. It is distributed across:

• Cell suppliers: Material composition, origin certificates, recycled content shares
• Internal systems: ERP, PLM, lab data, quality assurance
• External partners: CO2 calculations, testing institutes, certifiers

The effort for initial collection depends heavily on how well your existing data infrastructure is set up. Manufacturers who already use a PLM system and have structured supplier data reach their goal faster than companies working with Excel-based processes.

Cost Factor 2: Software and Infrastructure

There are fundamentally three paths for creating and managing battery passports:

• In-house development: Building an internal solution. High initial costs (development team, infrastructure, maintenance), full control. Realistic only for large corporations with their own IT department.
• ERP integration: Extending existing systems (SAP, Oracle). High integration costs, long project timelines, dependency on ERP vendor.
• Specialized SaaS solution: Ready-made software tailored to battery passports according to DIN SPEC 99100. Low entry costs, fast implementation, ongoing updates when standards change.

DPP Hero is such a specialized SaaS solution. The software maps the DIN SPEC 99100 data structure with guided input, validation, and export, so you do not have to work through the specification yourself. A step-by-step guide shows what the creation process looks like in practice.

Cost Factor 3: Personnel Costs

Regardless of the chosen software, internal resources are needed. Typical roles:

• Battery Passport Project Manager: Coordinates data collection, defines processes, manages supplier coordination. Estimated effort: 20-40% of a full-time position (introduction phase), then 10-20%.
• Specialist departments: Quality, procurement, production, and logistics contribute data. Occasional effort, especially during initial collection.
• CO2 expert: For the carbon footprint calculation per PEFCR. Can be staffed internally or sourced externally.

The key factor: the better the software structures the process, the lower the personnel effort. A solution that works with guided input forms and validates data significantly reduces errors and follow-up questions.

Cost Factor 4: External Consulting

Not every company needs external consulting. But in certain cases it makes sense:

• CO2 calculation: When no internal LCA competence exists. Specialized consulting firms calculate the Product Carbon Footprint per PEFCR.
• Supply chain due diligence: Review of due diligence obligations and building a management system. Particularly relevant for complex international supply chains.
• Regulatory consulting: For interpreting the EU Battery Regulation in your specific business context.

Important: external consulting complements the software, it does not replace it. The consultant helps with strategy, the software handles structured data entry and export.

Cost Factor 5: Ongoing Maintenance

A battery passport is not a one-time project. After the initial setup, ongoing tasks arise:

• Data updates: When cell chemistry changes, new suppliers are onboarded, or CO2 values are updated
• New products: Every new battery variant needs its own passport
• Standard updates: When EU Delegated Acts or the DIN SPEC are updated, existing passports may need adjustment
• Recycled content quotas: Recycled content shares must be documented from specific deadlines and increase over time

With a SaaS solution like DPP Hero, standard updates are included in the subscription. You do not need to track changes yourself.

Cost Comparison: In-House vs. Software

What Does Non-Compliance Cost?

The most important cost comparison is not software A vs. software B, it is investment vs. non-compliance. From 18 February 2027, EV batteries, industrial batteries over 2 kWh and LMT batteries cannot be placed on the EU market without a valid battery passport.

The consequences:

• Market access ban: Your products cannot be sold. Production standstill, storage costs, lost revenue.
• Fines: Article 93 of the EU Battery Regulation requires every member state to set effective, proportionate and dissuasive penalties; the amounts are set nationally.
• Contractual penalties: When you cannot fulfill delivery obligations to OEMs.
• Reputational damage: Public reports of violations, loss of trust with business partners.

Measured against these risks, the investment costs for a compliant battery passport are minimal.

What the software actually costs

We start with the block we can prove, because it is ours. With DPP Hero you pay monthly, and price plus quota gives a cost per published passport:

That is the floor of the calculation, not the total. Software is the block you know precisely in advance; the others depend on your volume and your supplier structure.

The other cost blocks, and why we do not put figures on them

Ranges for marking, audits and consulting circulate online. We do not copy them, because we have not verified them ourselves and because without your volume they say nothing anyway. What we do instead: tell you which blocks exist and where to ask for the real price.

• GS1 identifiers: you need a GTIN for the model and a GLN for your company. Prices come from your national GS1 organization. Note: a GLN on its own does not include a GTIN.
• Physical marking: under Article 13(7) the QR code has to be printed or engraved indelibly. Stickers, laser and direct printing differ considerably per unit; ask your label or manufacturing partner with your annual volume. An NFC tag does not replace the QR code today: Article 13(8) does allow the Commission to prescribe alternative smart labels alongside or instead of the QR code, but that act does not exist yet. Anyone using NFC pays for it on top, not instead of the code.
• Conformity assessment and verification: the reliability of recycled content and carbon footprint data is verified by a notified body as part of your quality management system. The bodies quote their own prices; which ones are designated for batteries is listed in the European Commission's NANDO database.
• Supply chain data collection: the most expensive and most underestimated block. It depends on how many suppliers have to give you material data and how well your contracts already cover it.

One point only shows up when you lay the items side by side: a large share of them is fixed. The GLN applies per company, the GTIN per model, and conformity assessment under Article 17(1) hangs on the quality management system, not on the number of units. A maker building 200 batteries a year carries the same base amount as one building 200,000 and spreads it over a thousand times fewer units. For small manufacturers the question about the fixed cost block therefore matters more than any per unit price.

What you can work out yourself

Take your annual volume and calculate three figures: software cost per passport from the table above, marking cost per unit from your manufacturing partner's quote, and the one-off cost for identifiers and verification. Those three together are defensible. Anything beyond that, quoted to you by someone who does not know your volume, is guesswork.

Separate year 1 from the following years. Calculate two figures instead of one. Year 1 contains the initial data collection effort, internal coordination, any external consulting and twelve months of software cost. In the steady state, only the software cost, the upkeep of changed data and the effort for new models remain. The difference is substantial, and quoting only the year-1 figure significantly overstates the ongoing burden. The reverse holds too: calculating only the following years understates the entry. For the decision you need both figures, and for a comparison with an in-house build, the same period on both sides.

What conformity assessment costs

One cost block rarely appears in software quotes and still hits you: conformity assessment. Article 17(1) allows two routes for series-produced batteries. Module A, internal production control under Annex VIII Part A, is declared by the producer on their sole responsibility; there are no third-party fees here, only the effort for the technical documentation.

Module D1 under Annex VIII Part B is the more expensive route. There the producer applies to a notified body for assessment of their quality system, and under point 6 that body carries out ongoing surveillance of whether the obligations from the approved system are met; for that it gets access to manufacturing, inspection, testing and storage facilities. So do not budget for a single audit, but for a recurring one.

Frequently Asked Questions

Is there an official price list for the battery passport?

No. The EU Battery Regulation mandates the battery passport but does not prescribe how it must be technically implemented. Costs depend on the chosen implementation approach and the complexity of your products.

Can I create the battery passport for free?

Data entry is theoretically possible in any format, including Excel. But without validation, structuring according to DIN SPEC 99100, and machine-readable export, the decisive added value is missing. Details about the transition are available at From Excel to Battery Passport.

How much does DPP Hero cost?

DPP Hero offers various subscription plans. Current pricing is available on our pricing page.

What costs come after the initial setup?

Ongoing costs include the software subscription, personnel effort for data maintenance with new products, and potentially updated CO2 calculations when the supply chain changes.

Is a battery passport worthwhile for small manufacturers?

Yes, the requirement applies regardless of company size. Small manufacturers especially benefit from SaaS solutions because they do not need to build their own IT infrastructure. Use our checklist to check which steps are relevant for you.
