Purpose and goal
The overall aim for the project is to increase circularity and sustainability in the automotive industry by ensuring high quality electrical joints subjected to thermal- and mechanical fatigue. The project aims to decrease the use of raw materials, decreased number of failures in battery systems and enabling 2nd life opportunities for battery packs. The project will create a new, improved method for design and testing, and a guideline for optimized properties in electrical joints.
Expected effects and result
The project will lead to increased knowledge regarding design and testing of electrical joints, which in turn will lead to increased capacity of electrical vehicles, decreased use of raw materials, improved ability to reuse battery packs and a more efficient design- and production process for new EVs.
Planned approach and implementation
The project is divided into six work packages: AP1 Modern busbar design and implementation AP2 Resistance measurements AP3 Welding concepts AP4 FEM simulations AP5 Fatigue testing and method development AP6 Project management and dissemination
