Why look at it by category
A list of data fields is hard to act on. A list of categories, each with an owner, turns into a work plan: you know whom to ask and what evidence to expect. The categories below match how Annex XIII groups the information.
Battery and manufacturer identification
Who made the battery, which model it is, and when and where it was made. This is normally data you hold yourself, but it has to be consistent across your systems, because the passport is linked to the product through a persistent identifier.
Composition and materials
What the battery is made of, including its chemistry and the materials in it. Cell and material suppliers usually hold this, and you need it in a form you can check, such as a datasheet or a certificate.
Performance and durability
Capacity, expected lifetime and the other performance values the regulation lists. This is usually your own test and design data, which means the work is in collecting it from engineering into one record.
Carbon footprint
A declared carbon footprint for the battery, with the study behind it. The study draws on data from the manufacturer and from suppliers, so the quality of supplier input decides the quality of the result.
Supply chain information
Information about where materials come from and the due diligence behind them. Raw material suppliers and their upstream partners hold most of it, and it is often the slowest category to collect.
End of life
Information for dismantling, reuse and recycling. It is mostly your own technical documentation, written for people who will handle the battery after you.
Different readers see different parts
Not everything in the passport is public. Some information is open to anyone who scans the code, some is for parties with a legitimate interest, and some is for authorities. The rules for the access levels are still being completed, so keep each value tagged by who should see it.
What this means in practice
- Give every category a named owner, inside your company or at a supplier.
- Ask for evidence with each value, so a reviewer can check it.
- Record who approved each value and when.
- Track expiry dates for certificates that support the data.
