EU Guidance on Digital Battery Passport Data Point

The European Commission has published a guidance document presenting the data points expected in the Digital Battery Passport under the EU Battery Regulation.

The requirement to provide a Digital Battery Passport will apply from 18 February 2027 to electric-vehicle batteries, light means of transport batteries and industrial batteries with a capacity above 2 kWh.

The Commission’s document provides an overview of 71 aggregate data points. It is intended to help companies understand which information may need to be collected, managed and made available through the passport.

Five main data areas

The data points can be grouped into five broad areas:

• Identification and manufacturing: manufacturer details, battery identifiers, serial numbers, manufacturing location and date.
• Materials and circularity: critical raw materials, recycled content, substances of concern and information relevant to collection, reuse and recycling.
• Performance and durability: battery capacity, energy efficiency, expected lifetime, warranty and performance characteristics.
• Compliance and repairability: declaration of conformity, applicable labels, spare-part information, dismantling instructions and safety information.
• Usage information: state of charge, state of health, remaining capacity, performance loss and other dynamic battery data.

Different data-point statuses

The guidance categorises each data point according to whether it is mandatory, optional, applicable only in specific cases, or not required to be completed or displayed.

This distinction is important because not every data point will apply to every battery or every economic operator. Companies should therefore assess the guidance against the battery categories they place on the EU market and the role they have in the supply chain.

What this means for companies

The document is not legally binding and does not replace the requirements of the EU Battery Regulation. However, it provides a practical reference for a more consistent approach to preparing battery information for the Digital Battery Passport.

The Commission describes the guidance as a living document. It may therefore be updated as the Digital Battery Passport framework, technical standards and implementation measures develop.

Manufacturers, importers and other relevant operators should use the guidance to map available data, identify gaps across suppliers and internal systems, and distinguish static product information from data that may need to be updated during the battery’s use phase.
