Abstract [en]
The batteries that power electric vehicles have grown to be a crucial part of their operation. The battery pack joining method plays a critical role in determining the battery pack's overall performance and environmental impact. This thesis aims to conduct a comparative environmental impact analysis of EV battery pack joining methods to identify the most sustainable method.
The three joining methods considered in this study are welding, mechanical joints, and adhesives. Each joining method's environmental effect is assessed using the Life Cycle Assessment (LCA) technique. The LCA includes the production, use, and disposal phases of the battery pack.
The results show that the mechanical joint method has the lowest environmental impact, followed by adhesive and welding methods, respectively. The mechanical joining method also has many advantages like being economical, consistent and less maintenance. This study contributes to the knowledge of EV battery pack joining methods and their impact on the environment.
