What does Battery Passport mean?
The Battery Passport is the EU Regulation 2023/1542 digital product passport for batteries.
From 18 February 2027, LMT batteries, industrial batteries above 2 kWh and electric vehicle batteries need an electronic battery passport when placed on the EU market or put into service. The passport contains battery model information and, where applicable, individual battery data from use.
Why does it matter for DPP and compliance?
The Battery Passport is the first major mandatory DPP use case with a fixed date. It requires access layers for public information, authorities, notified bodies and legitimate-interest actors such as repair, second-life and recycling operators.
What should teams prepare?
Manufacturers should prepare battery model, serial number, QR code, carbon footprint, performance data, state of health, dismantling information and test reports as versioned data objects. The key architectural point is separating model-level passport data from individual battery history.
