From 18 February 2027, LMT batteries, industrial batteries above 2 kWh and electric-vehicle batteries generally require an electronic battery passport. Companies should test data, responsibilities and technical processes now.

## In brief

- Confirm battery type, capacity and legal scope first.
- Combine data from engineering, purchasing, production and suppliers.
- Separate public information from restricted information technically.

## Determine scope and granularity

Document the battery category, capacity, economic operator and placing-on-the-market date, then decide whether data belongs at model, batch or individual level.


## Build the data inventory

Map every required field to its source, owner, update cycle, access group and supporting evidence, including performance, composition and carbon-footprint information where applicable.


## Pilot and operate

Publish approved records through stable identifiers, test mobile and machine access, consider the EU DPP Registry test environment and define controlled updates over the lifecycle.


## Frequently asked questions

### When does the battery-passport requirement begin?

Article 77 sets 18 February 2027 for LMT, industrial batteries above 2 kWh and EV batteries; individual applicability should still be checked.

### Is all battery-passport data public?

No. The Regulation distinguishes access groups, which the technical solution must enforce.
