Battery Passport: Public Data and Limitations

A digital passport links a battery to model information and, subject to access rights, individual battery information. From 18 February 2027, it applies to electric vehicle batteries, light means of transport batteries and industrial batteries above 2 kWh placed on the market or put into service.

A QR code supplies a link or identifier. Recognizing GS1 syntax and its checksum proves neither that a passport exists nor that the battery is authentic. A QR code can lead to an ordinary page, an authentication screen or an unreachable resource.

Public information includes manufacturer, model, chemistry and some nominal characteristics. It is not a health assessment of a used battery. Individual measurements, actual cycles and certain dismantling details have specific access conditions.

Carbon footprint, recycled materials and due diligence follow their own schedules and conditions. They must not all be described as mandatory on 18 February 2027. Consult the legislation and FAQ for each category and deadline.

What a model passport describes

Manufacturer, chemistry, rated capacity or expected durability describe declared specifications. They do not measure your individual battery’s present performance.

Buying a used battery or vehicle

Ask the seller for a dated individual assessment and pack documents. Expected cycles are not actual cycles completed; a document reference does not prove compliance.
