Thesis work: 30hp - Feasibility study of LIB starter batteries in heavy vehicles

Introduction and Background: Thesis work provides an opportunity to learn more about Scania and establish professional connections. Many current employees started their careers at Scania by completing their degree project. TRATON is a group that includes brands such as MAN, Scania, Volkswagen Truck & Bus, and International, with a focus on sustainable mobility in transportation. As part of TRATON, participants collaborate with industry professionals and contribute to ongoing projects. Thesis work at TRATON offers experience within the organization and opportunities to participate in innovative projects while developing professional relationships. For more information: www.traton.comObjectiveThe objective of this thesis is to analyse the cost, efficiency, performance, and lifespan trade-offs associated with employing lithium-ion batteries as 24 V starter batteries in commercial vehicles. Currently, lead-acid batteries are recommended and widely regarded as a cost-effective solution for this application. However, the growing market on Lithium ion batteries (LIB) presents opportunities for adopting the technology into the commercial vehicle and seeks to identify the necessary changes in system design when transitioning from the current approach. The objective of this study is to identify a viable solution and to develop an implementation plan for its integration into commercial vehicles.Job DescriptionThe project is intended to analyse the problem using a theoretical framework.Conduct a comprehensive literature review.Examine driving profiles and available historical data.Develop mathematical models for the selected concepts.Construct thermal and electrical models.Carry out cost modelling.To complete the thesis: A comparative analysis and rationale for the chosen concepts will be presented, supported by corresponding cost and mathematical models.Education/program/focusYou are a curious and motivated individual with a solid academic background and a strong interest in sustainable technologies and energy systems.
