EU Releases Updated Guidance for EUBR Battery Passport
Beginning on February 18, 2027 the EU Battery Passport will become mandatory for electric vehicle (EV), light means of transport (LMT) and industrial batteries above 2 kWh. The battery passport will operate through a decentralised system, with detailed battery information maintained by the responsible economic operator.
Who can access the Battery Passport data?
While some Battery Passport data would be accessible by the public, the Commission launched an open consultation on a draft implementing act to define who may access restricted Battery Passport information and how that information can be used. Feedback on the draft implementing act is open until November 16th, 2026.
What are the 71 data points that must be included in the Battery Passport?
Per the Battery Passport guidance updated on October 19th, the following are the 71 data points required under the EU Battery Passport, with some variations in requirements depending on battery type and use.

For a detailed list of which data points are required by the February 2027 deadline, which are dependent on battery type, and which are only required 'if applicable', refer to the EUBR Battery Passport guidance.
What about batteries excluded from the Battery Passport requirements?
Batteries excluded from Battery Passport requirements will be subject to the EUBR due diligence requirements. QR codes must be added to all battery types subject to the EUBR starting February 2027 - the same deadline as the Battery Passport - however, due diligence requirements and their associated data points are not due until August 2027. The EU has not yet released guidance related to the specific due diligence requirements for batteries subject to EUBR but excluded from the Battery Passport.
