The EU Battery Regulation introduces a new way of collecting and sharing information on batteries. The Battery Passport will become mandatory from 18 February 2027 for electric vehicle (EV) batteries, light mobility vehicle (LMT) batteries and industrial batteries with a capacity of over 2 kWh that are placed on the EU market or put into service.
The aim of the battery passport is to improve the traceability and transparency of batteries and to facilitate the use of battery-related information throughout their entire life cycle.
What is a digital battery passport?
A digital battery passport is an electronic record linked to an individual battery, which can be accessed via a QR code on the battery. From 18 February 2027, the battery passport will become mandatory for electric vehicle batteries, batteries for light mobility vehicles (LMTs) and industrial batteries with a capacity of over 2 kWh.
The battery passport brings together information on the battery’s origin, technical characteristics, performance, materials, carbon footprint and recyclability. Information relating to an individual battery may also include data generated during its use, such as the battery’s State of Health (SOH).
Not all the information in the battery passport is public. Some of the information is available to everyone, whilst access to more detailed information is restricted according to its intended use and the user’s role.
Information throughout the battery’s life cycle
The battery passport is designed to improve the traceability and transparency of a battery throughout its life cycle. The information can be utilised during the battery’s use and maintenance, as well as later when assessing options for reuse, second-life applications or recycling.
In August 2026, the European Commission published new guidelines to support the introduction of the Battery Passport. The guidelines summarise the Battery Passport requirements in 71 data points, the applicability of which depends on the battery category. The guidelines may be further updated before the requirements come into force.
Celltech Prepares for Upcoming Requirements
The digital battery passport forms part of the wider EU Battery Regulation, which is gradually introducing new requirements for battery manufacturing, labelling, accountability, traceability and life-cycle management.
Celltech is monitoring developments in the requirements of the Battery Regulation and the digital battery passport, and is preparing for future changes in collaboration with manufacturers, suppliers and other players in the battery supply chain.
