Battery Data Models
To support rapid and consistent implementation of the EU Battery Passport, Path.Era provides structured battery data models that enable efficient, accurate data exchange across the value chain.
Regulatory Context
Under the EU Battery Passport Regulation, manufacturers placing batteries on the market are required to report detailed information1, including but not limited to:
- Product Carbon Footprint (PCF)
- Battery chemistry and material composition of the cathode, anode, and electrolyte
- Material content and composition
- Recycled and renewable material content
- Battery-specific performance data
To meet these obligations, upstream suppliers within the battery value chain are responsible for providing accurate, timely data to their customers. This enables downstream operators to calculate and report the required information based on their own manufacturing processes, in full compliance with EU regulations2.
Path.Era Battery Data Models
To streamline data exchange across the value chain, Path.Era has developed a structured approach using aspect model files for material-related data transfer from supplier to customer. This structured data models ensure efficient transparency and traceability across the battery lifecycle, in line with the most recent understanding of battery regulation and best practices of Catena-X3:
- Product Carbon Footprint: Battery regulation requires reporting the PCF contributions from four predefined stages of the battery value chain4.
- Declarable Substance: Captures material data as it progresses through various processing stages (e.g., metal refining, precursor production, active material synthesis).
- Secondary Material Content: Reports recycled content using an adapted version of the respective Catena-X aspect model5, ensuring traceability and compliance with circular economy goals.
- Battery Type Information: Consolidates data on battery chemistry and material composition (cathode, anode, electrolyte) along with electrochemical performance for specific battery models6.
