The transition toward electric mobility and renewable energy storage requires increasingly stringent sustainability standards. In this context, the Battery Passport was born: a digital registry that will become mandatory in the European Union starting in February 2027 for electric vehicle (EV) batteries, light means of transport (LMT) batteries, and industrial batteries with a capacity over 2 kWh.

In line with EU Regulation 2023/1542 and the DIN DKE SPEC 99100 technical specifications, this tool acts as a Digital Product Passport (DPP). Its purpose is to securely, transparently, and immutably store crucial data on the device’s entire lifecycle: from the origin of raw materials and the carbon footprint to dynamic data on the state of health (SoH) and state of charge (SoC).

Leading certification services companies like ECM are already offering integrated digital solutions to meet this upcoming deadline. Through scalable cloud platforms and the use of secure APIs, manufacturers can centralize static and dynamic data, ensuring regulated, role-based access for authorities, recycling operators, and consumers (via QR codes).

The benefits are systemic: manufacturers reduce compliance risks, fleet managers optimize the residual value of used vehicles, and recyclers obtain precise information to recover valuable materials such as lithium, cobalt, and nickel. Therefore, the passport is not a mere bureaucratic requirement, but the key infrastructure for a truly circular economy.
