Commission guidance 2.0 — 15 August 2026 · local readiness tool

Find the battery-passport data you still need to collect

Choose the battery category and mark whether you already hold usable evidence for each data point. The tool applies the Commission guidance category-by-category and keeps your answers in this browser session only.

From 18 February 2027, battery passports are required for EV batteries, LMT batteries and industrial batteries above 2 kWh placed on the EU market or put into service. This mapper is a preparation aid, not a legal opinion, conformity assessment, registry submission or passport issuer.

Scope and sources

The mapper contains all 71 data-point rows from the Commission's version 2.0 guidance dated 15 August 2026 and distinguishes mandatory, optional, conditional and February-2027-not-required/displayed states by battery category. It deliberately does not determine whether a battery is compliant or ready for registration.
