IDEA project: Data sharing for circular end-of-life EV batteries

New project to strengthen information and data sharing for circular management of electric vehicle batteries

IDEA is a Swedish-funded feasibility project (Nov 2025–Oct 2026) to fix the data gaps that make end-of-life EV batteries risky and hard to keep circular. By mapping today’s information flows and aligning with EU standards and the upcoming battery passport, partners will design a digital concept that links emergency services, workshops, dismantlers, reusers, and recyclers.

A new project, IDEA: Information and Data Sharing for Circular Flows of End-of-Life Electric Vehicle Batteries, has now started. By improving information flows and data sharing between actors such as emergency services, workshops, dismantlers and re-users, the project will create better conditions for safe and circular battery management.

The project is funded by the Swedish Energy Agency through the call Impact Innovation: Net Zero Industry 2025 and runs from November 2025 to October 2026.

Improved information sharing throughout the value chain

The aim of the project is to improve information flows and data sharing between actors who handle electric vehicle batteries when they are no longer used in vehicles. This applies to, for example, emergency services, workshops, dismantlers, logistics companies and actors working with reuse and recycling.

Through a feasibility study, the project will:

map out what information flows look like today and where there are gaps
analyze relevant European initiatives and standards
identify risks that can arise when important information is missing or not shared
develop proposals for how digital tools can support actors throughout the value chain

The work will prepare for the upcoming EU battery passport and contribute to better safety, increased resource efficiency and reduced climate impact.

Foundation for future digital solution

Based on the project’s results, a concept for a digital solution will be developed. The concept will serve as a basis for future implementation on a larger, industrial scale, as well as for upcoming national and European initiatives in circular battery use.

Project partners

The project is implemented by:

Swedish Car Recyclers’ Association (SBR)
Car return
The Swedish Motor Industry Association (MRF)
Swedish automotive industry
Chalmers Industrial Engineering (project manager)
