What are Digital Product Passports?
A digital product passport is a regulatory framework under the European Union’s Green Deal. Its purpose is to give every product sold in the EU a standardized digital identity that makes its environmental impact and lifecycle information transparent.
Think of the DPP as a blueprint for transparency rather than a single piece of software. It establishes rules that require:
- Data Collection: Manufacturers must capture defined sustainability and circularity data for their products.
- Data Accessibility: This information should be easily available to regulators, businesses, and consumers (often via a QR code).
- Empowered Decisions: By making this data visible, the DPP supports recycling, repair, and more sustainable purchasing choices.
While the framework applies broadly to sectors like textiles, electronics, and construction, batteries have been chosen as the first test case.
Are Digital Product Passports and Battery Passports the Same?
No. The difference is best described as general vs. specific:
- Digital Product Passport: The overarching regulatory framework.
- Battery Passport: The first concrete implementation of the DPP, tailored to batteries.
Under the EU Battery Regulation, the Battery Passport takes DPP principles and turns them into legally binding requirements for what data must be included, how it should be shared, and when. In practice, the Battery Passport sets the precedent for how DPPs will be applied to other industries.
Core Principles That Battery Passport Software Must Follow
Any Battery Passport solution must align with the foundational rules of the DPP framework. These principles are non-negotiable:
- Data Sovereignty: The data owner (e.g., manufacturer) must control who can see which information. A consumer might only access recycling guidance, while a recycler can view detailed chemical data.
- Interoperability: The system must integrate smoothly with other platforms, using shared standards (like those being advanced by Catena-X) to connect suppliers, manufacturers, and recyclers.
- Verifiability & Data Integrity: Data must be trustworthy. Blockchain and cryptographic methods ensure that key records are immutable and independently verifiable.
Skipping any of these principles risks building software that won’t survive regulatory or industry expectations.
What is Battery Passport Software?
Battery Passport Software is like the brain behind battery transparency; it creates a secure digital record that follows a battery through every stage of its life. From mining to manufacturing, daily use, and recycling, it keeps the data accurate, trusted, and always up to date. This way, businesses and consumers can finally see the full story of what powers their world.
It goes far beyond being a simple digital document. This software is responsible for:
- Aggregates information from suppliers, ERP systems, and IoT sensors.
- Standardizes it into a consistent format.
- Secures it with tamper-proof technology.
- Provides role-based access to different stakeholders.
- Generates insights and compliance reports automatically.
In short, it turns regulatory compliance into actionable business intelligence.

How Does Battery Passport Softwares Works?
Battery passport software works by first gathering both static data from manufacturing systems and live performance data from the battery itself. It then standardizes and secures this information, often using blockchain for integrity and cloud storage for protection.
Finally, it delivers tailored insights to stakeholders, whether that’s a consumer checking recycling details, a regulator reviewing compliance, or a recycler accessing disassembly instructions.
Phase 1: The Data Ingestion Engine
The foundation of a battery passport begins with comprehensive data collection across the value chain. The software connects to multiple systems to capture both static and dynamic information.
Static Data – The Battery’s Birth Certificate
This data is created at the design and manufacturing stage and forms the battery’s core identity. Through APIs, the software integrates with enterprise systems to capture:
- From ERP & PLM Systems: details such as material chemistry, supplier identity, production date, factory location, and associated carbon footprint.
- From Supplier Portals: verified records on raw material origins, recycled content, and due diligence compliance.
Dynamic Data – The Battery’s Live Health Monitor
Beyond its birth data, the passport tracks the battery’s real-world performance. The software establishes secure IoT connections to the Battery Management System (BMS), streaming live metrics including:
- State of Health (SoH)
- State of Charge (SoC)
- Temperature and charge cycles
- Long-term performance history
Lightweight IoT protocols like MQTT enable this continuous data flow. Together, static and dynamic data create a digital twin—an evolving digital identity of the physical battery.
Phase 2: The Data Core
Data is only valuable if it’s consistent, reliable, and trustworthy. The data core ensures this by transforming raw inputs into a structured, secure source of truth.
Standardization – Building a Common Language
Suppliers and systems provide data in different formats. The software processes these inputs through a standardized data model, often aligned with frameworks like Catena-X. This guarantees uniformity, for instance, that carbon footprint data carries the same meaning across all suppliers.
Security – Protecting Trust and Integrity
Credibility relies on tamper-proof data. To achieve this, the system applies multiple safeguards:
- Blockchain/DLT: Key records—such as carbon footprint declarations or ownership transfers—are hashed and stored on distributed ledgers like Hyperledger Fabric, creating an immutable audit trail.
- Cloud Security: All information is encrypted both in transit and at rest, ensuring protection against unauthorized access.
Phase 3: The Access Layer
The final step ensures stakeholders access only the information relevant to them, delivered securely and on demand.
Role-Based Access Control
A single QR code can act as the gateway, but permissions differ by role using frameworks like OAuth 2.0 and OpenID Connect:
| Stakeholder | Access / Insights |
| Consumers | Safety guidance, recycling steps, battery’s carbon footprint |
| Regulators | Full compliance data for verification |
| Authorized Recyclers | Detailed chemical composition, disassembly instructions |
| Second-Life Marketplaces | Certified feeds on State of Health (SoH) to evaluate resale potential |
Turning Data into Action
The battery passport does more than store data, it turns it into action. On the backend, it automatically generates compliance reports, tracks real-time ESG metrics, and uses predictive models to forecast the battery’s remaining life.
