D2R
Diagnosis, Repair, Reuse of electric vehicle battery packs and their sub-assemblies
The D2R (Diagnosis, Repair, Reuse) project aims to implement an innovative, multi-brand solution to extend the life of electric vehicle batteries and encourage their reuse.
This project is based on a complementary approach combining diagnostics, repair and reassignment, to meet the technical, economic and environmental challenges posed by the electrification of the vehicle fleet. Faced with the lack of manufacturer data and the absence of standardized tools, D2R is developing solutions for assessing the state of health (SOH) of batteries, repairing them where possible, or reusing them in stationary or soft mobility applications.
The approach is intended to be comprehensive: diagnosis is based on OBD, OTA and off-board methods, combined with experimental models and tools to guarantee robust, reproducible results. Repair is based on standardized procedures and an ecosystem of spare parts, while battery reuse is part of a circular economy approach on a regional scale.

Norauto International is piloting the project and contributing its business and operational expertise. The LAMIH laboratory (CNRS/UPHF) is involved in modeling, diagnostics and assessment of aging. Neo-Eco, as a subcontractor, is responsible for dismantling, traceability and end-of-life management. Together, the partners are implementing an integrated, replicable approach to more sustainable mobility.
The official launch of the project takes place on June 12 in person at the Norauto site in Villeneuve d'Ascq in the presence of the region.
A LAMIH/Norauto research seminar will be held on June 24 in the T. Tison amphitheater of the CISIT building.
