Battery Passport QR Code: Understanding the Result

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.

Read a QR code step by step

Use the camera, import an image or paste the link. The QR is decoded locally; only its link is sent to the server to retrieve public data. A QR need not contain the actual passport data.

Why might a link fail?

An error may identify a Wi-Fi QR, an ordinary page, an unsupported format, an unavailable source or protected access. None of these cases generates a substitute demonstration battery.
