Sammanfattning
The transport industry is facing an extensive technological shift towards electrification to build an environmentally sustainable future. Scania, one of the leading players in the field of trucks is also working towards electrification of their vehicles through the use of their modularity. This thesis is aimed towards the modular approach of electrification of trucks from a long-term perspective. The purpose of this thesis thus is to analyze the existing modules of Scania trucks to determine which of these modules are not necessary for an electric truck, the modules that need to be either added or modified in order to satisfy the needs of electrification and to analyze the relations between these modules. This thesis aims to propose a new modular toolbox that can be shared between both Internal Combustion Engine (ICE) powered trucks and electric trucks. This thesis also aims to propose a strategical layout for an electric truck through placing these modules on the vehicle layout on a holistic level. In order to achieve the said purpose, this thesis work is divided into three main chapters, pre study, nodular toolbox analysis and battery layout analysis. Pre study is aimed at getting an in-depth knowledge regarding Scania, modularization, ICE trucks and electric trucks. This was done through a detailed literature review and through conducting various interviews with experts from all the concerned fields. Modular toolbox analysis was aimed at identifying the affected modules while transitioning from ICE powered trucks to electric trucks. This chapter also deals with the relations between these modules and the strategic placements of these modules on a truck. This was done through benchmarking, literature review on recent technological developments, brainstorming and by conducting interviews with experts. Battery layout analysis was aimed at proposing a strategical layout for an electric truck from an energy storage perspective for different scenarios. This was done using CAD modeling and assembly in Catia V5. Additionally, the results from these analyses were compiled and presented in the form of a new modular toolbox for electric trucks, strategical layouts for different scenarios and the amount of energy storage that can be placed on the truck for each scenario. Finally, some recommendations were given for the right way to move forward with electrification from a layout perspective along with some recommendations for future work that will bolster the finding of this thesis and take the research forward. It is hoped that this thesis will provide a guide work towards electrification of vehicles from a modular and layout approach.
