Battery Passport & EU Regulation
What exactly is a battery passport?
A battery passport is a digital product passport specifically for batteries that becomes mandatory from February 18, 2027. It makes information on material composition, CO₂ carbon footprint, supply chain due diligence, circularity, performance, and labeling transparent and machine-readable across the entire battery lifecycle. The legal basis is the EU Battery Regulation 2023/1542, Article 77.
What is a Battery Passport? Everything You Need to KnowWhen does the battery passport become mandatory?
From February 18, 2027 under the EU Battery Regulation 2023/1542. This applies to electric vehicle batteries, industrial batteries with a capacity exceeding 2 kWh, and LMT batteries (Light Means of Transport). Since data capture covers seven categories with extensive required fields, early preparation is recommended.
EU Battery Regulation 2027: Timeline and RequirementsWhich battery types require a battery passport?
Three categories: electric vehicle batteries (EV), industrial batteries with a capacity exceeding 2 kWh, and batteries for light means of transport (LMT) — including e-bikes and e-scooters. Portable batteries (e.g., in smartphones) and automotive starter batteries are currently not affected.
What is the difference between a battery passport and a digital product passport?
The battery passport is the first concrete implementation of the digital product passport (DPP). The ESPR (Ecodesign for Sustainable Products Regulation) will gradually extend the DPP to additional product categories. The battery passport has its own legal basis (EU Battery Regulation 2023/1542) and a fixed start date on February 18, 2027 — making it the forerunner for all future digital product passports.
What is DIN SPEC 99100?
DIN DKE SPEC 99100:2025-02 is a German pre-standard that defines the data structure for the digital battery passport. It describes seven data categories: identification, materials and composition, CO₂ carbon footprint, supply chain due diligence, circularity, performance and durability, and labeling and EU declaration of conformity. The specification is widely expected to form the basis for the upcoming EU delegated acts and serves as the reference for DPP Hero's data structure.
DIN SPEC 99100 Explained: The Standard Behind the Battery PassportWho is responsible for creating the battery passport?
The economic operator placing the battery on the EU market is responsible — meaning manufacturers, importers, or authorized representatives. They bear responsibility for the accuracy and completeness of the battery passport data. DPP Hero supports this process as a creation and management tool by structuring data capture according to DIN SPEC 99100.
DPP Hero Platform
How does DPP Hero work?
DPP Hero guides you through all seven data categories of DIN SPEC 99100 in structured steps: identification and master data, materials and composition, CO₂ carbon footprint, supply chain due diligence, circularity, performance and durability, and labeling. Each step clearly indicates which fields are required and which are optional. Once your data is complete, you publish the product and can export the battery passport as PDF or JSON, generate a QR code, and share a public product page.
Do I need technical skills to use DPP Hero?
No. DPP Hero is designed as a self-service tool — create your account, add a product, and you'll be guided step by step through the data entry. No IT project and no demo call required. For companies that want to integrate data programmatically, a REST API with full documentation is available from the Scale plan.
Can I import existing product data?
Yes. From the Business plan, you can import product data via CSV file — including a downloadable template and automatic column mapping. From the Scale plan, a REST API is also available for programmatic integration with ERP or PLM systems, including bulk import of up to 500 products per request.
From Excel to Battery Passport: How to Make the TransitionWhat export formats are available?
DPP Hero offers three export formats: PDF document for internal documentation and sharing, JSON file according to DIN SPEC 99100 for machine processing, and QR codes as PNG (print-ready) or SVG. All exports are available for published products — both via the dashboard and the REST API.
Can I collect data directly from suppliers?
Yes. With the share link feature (from the Business plan), you create a time-limited link for specific data sections — e.g., material composition or manufacturer details. Your supplier opens the link, enters the data, and submits it. The information lands directly in your product without the supplier needing their own account.
Supply Chain Due Diligence: Requirements for Battery ManufacturersWhat exactly is DPP Hero?
DPP Hero is battery passport software based on DIN SPEC 99100 — a creation and management tool that enables economic operators to capture their product data in a structured format, export it as PDF or JSON, and share it via QR code. Responsibility for the accuracy and completeness of the data lies with the user as the economic operator.
Pricing & Subscription
Can I try DPP Hero for free?
Yes. The Free plan lets you create one product and test the entire workflow — all seven steps, PDF and JSON export, QR code, and public product page included. No credit card and no time limit. Features like share links, CSV import, and the REST API are available from the paid plans.
Can I change my plan at any time?
Yes. Upgrades take effect immediately — you can start creating more products and use additional features like share links, CSV import, or the REST API right away. Downgrades take effect at the end of the current billing period. You can manage everything through your billing settings in the dashboard.
Is there a minimum contract period?
No. All plans are billed monthly and can be cancelled at any time. There is no minimum contract period, no setup fees, and no hidden costs. Prices are listed excluding VAT.
What happens to my data if I cancel?
After cancellation, you have 30 days to access your account and export your data as PDF or JSON. After that, data is deleted according to our privacy policy. Published product pages are deactivated at contract end. Previously downloaded exports remain yours, of course.
Data & Security
Where is my data stored?
All data is hosted exclusively in the EU — server location Germany. DPP Hero relies solely on EU data centers. Where US-based service providers are used, they are certified under the EU-US Data Privacy Framework. Details on all sub-processors can be found in our Data Processing Agreement (DPA).
Is DPP Hero GDPR compliant?
Yes. DPP Hero processes personal data exclusively in accordance with the GDPR and the German BDSG. We do not use any tracking or advertising cookies. A Data Processing Agreement (DPA) under Art. 28 GDPR is available and can be accessed via your organization settings or at /dpa.
Who has access to my product data?
Only the members of your organization have access to your product data in the dashboard. Published products are additionally accessible via the public product page and QR code — the scope of publicly visible data follows the DIN SPEC standard. Using the share link feature, you can selectively grant time-limited access to specific data sections for external partners.
Is my data encrypted?
Yes. All data is encrypted in transit via TLS and at rest with AES-256. Passwords are stored hashed and optionally protected by two-factor authentication (2FA). API keys cannot be viewed in plaintext after creation.
