Mandatory — do not dispose of with household waste
Battery status
Original (not repurposed)
Below 80% capacity the battery is suitable for a second life as stationary storage — the passport travels with it and its status is updated.
State of health (SoH)
Full charging cycles
Power fade
Negative events / accidents
These values are not filled in once — they come from the battery management system and are updated across the battery's whole life. That is why a battery passport is a register you maintain, not a document you file.
This is the public tier. The full specification is 71 fields.
The European Commission's guidance defines 71 data points for the battery passport — mandatory, conditional, and ones not to be filled until February 2027, different for each of the three battery categories. Our working breakdown by category, counted from the primary source, is available on request. If you are preparing a battery passport, save yourself the counting.
