Battery Passport supplier data: find the missing information before the deadline

The economic operator responsible for the finished battery passport may depend on data distributed across suppliers. The highest-value preparation step is therefore not the QR code — it is a controlled supplier-data inventory with owners and evidence.

Map Battery Passport gaps

Operational readiness

1. List the passport data points relevant to the battery category.

2. For each field, identify whether the responsible operator already controls the data.

3. Where a supplier controls it, record supplier, contact, requested format and evidence expectation.

4. Track missing/uncertain values separately from confirmed values.

5. Set internal cut-off dates ahead of the 18 February 2027 application date.

6. Keep legal-source references with each request so suppliers understand why the information is needed.

Important distinction

The Commission states that the battery passport obligation lies with the economic operator placing the finished battery on the market, while preparation can require data from the wider value chain.
