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 | Typical Effort | One-Time / Ongoing |
|---|---|---|
| Data Collection | High (initial effort) | One-time + updates |
| Software | Low to Medium | Ongoing (subscription) |
| Personnel | Medium | Ongoing |
| External Consulting | Optional | One-time |
| Ongoing Maintenance | Low | Ongoing |
Cost Factor 1: Data Collection
The largest cost block is almost always the initial data collection. The DIN SPEC 99100 defines over 90 data attributes that can be captured in a battery passport — approximately 40 of which are mandatory.
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 already covers all requirements of DIN SPEC 99100 — without you having to work through the 300-page standard 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. Punctual 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
| In-House Development | SaaS Solution | |
|---|---|---|
| Setup Time | 6-18 months | Ready immediately |
| Initial Costs | High (6 figures+) | Low (monthly subscription) |
| Maintenance | Own team required | By the provider |
| Standard Updates | Own tracking | Included in subscription |
| DIN SPEC 99100 | Implement yourself | Already built in |
| Risk | High (deadline 02/2027) | Low |
What Does Non-Compliance Cost?
The most important cost comparison is not software A vs. software B — it is investment vs. non-compliance. From February 18, 2027, no battery without a valid battery passport may be placed on the EU market.
The consequences:
- Market access ban — Your products cannot be sold. Production standstill, storage costs, lost revenue.
- Fines — Depending on the EU member state, five- to six-figure amounts.
- 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.
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.
