The EU digital battery passport will be accessible through a QR code. This code will be affixed to the battery itself and will contain a unique identifier that links to the digital record.
The EU regulations specify that some of the data within the passport might be publicly accessible, while other information will be restricted to authorized users only. This ensures transparency for consumers while protecting sensitive details only relevant to specific stakeholders within the battery lifecycle.
A bit more detailed:
The QR code should be able to be read without a special reader and without an additional app; all that is needed is a smartphone or tablet with a camera. According to current knowledge, the QR code could, for example, function as a kind of digital rating plate and be standardized according to IEC 61406. This means that the link (after scanning the code) will take you directly to the corresponding battery passport.
