Electric Vehicle Battery Pack - Flexible Module Design In the pursuit of cleaner and more sustainable transportation, the electrification of existing vehicles has emerged as a compelling solution. Retrofitting conventional vehicles with electric drive-trains is a promising step forward. However, one of the challenges in this attempt is the development of adaptable battery packs that can conform to the available space within different vehicle models. This thesis embarks on a journey to create the "Electric Vehicle Battery Pack - Flexible Module Design" a cutting-edge solution tailored to the specific needs of electric vehicle retrofits. A Battery Module is essentially a combination of battery cells.
