  1. 1. Customizable Contraction Hierarchies for Mixed Fleet Vehicle Routing : Fast weight customization when not adhering to triangle inequality

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Martin Larsson; [2023]
    Nyckelord :Contraction Hierarchies; Customizable Contraction Hierarchies; Vehicle Routing Problem; Battery Electric Vehicles; Mixed Fleet; Kontraktionshierarkier; Anpassningsbara Kontraktionshierarkier; Ruttplanering; Batteridrivna elfordon; Blandad fordonsflotta;

    Sammanfattning : As the transport industry shifts towards Battery Electric Vehicles (BEVs) the need for accurate route planning rises. BEVs have reduced range compared to traditional fuel based vehicles, and the range can vary greatly depending on ambient conditions and vehicle load. LÄS MER

  3. 2. Route Planning of Battery Electric Heavy-Duty Commercial Vehicles : Using Contraction Hierarchies and Mixed Integer Programming

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Datalogi

    Författare :Olle Delborg; Elias Insulander; [2023]
    Nyckelord :route planning; route optimization; contraction hierarchies; mixed integer programming; vehicle routing problem; electric trucks; electric vehicles; battery; openstreetmap; shortest path; Dijkstra;

    Sammanfattning : This thesis addresses route planning of Battery Electric Heavy-Duty Commercial Vehicles to enhance the reliability of electric vehicle transport. Collaborating with Scania, a Swedish truck manufacturing company, the goal is to develop a pipeline that uses open source data from OpenStreetMap and performs a modified Contraction Hierarchy in order to create a graph that can be used as input to a modified Vehicle Routing Problem formulation using Mixed Integer Programming.

  4. 3. Thermal Modelling of Permanent Magnet Synchronous Motor Windings in Heavy-Duty Electric Vehicles

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Ken Dahl; [2023]
    Nyckelord :PMSM; permanent magnet synchronous motor; synchronous motor; black-box modelling; black-box models; thermal modelling; lumped parameter thermal network; LPTN; electric machine; EM; EV; electric vehicle; winding;

    Sammanfattning : A significant challenge with permanent magnet synchronous motors (PMSMs) is thermal management. Thermal stress can lead to irreversible damage to components, and to enable efficient cooling, a thermal model is needed. LÄS MER

  5. 4. The application of financial analysis in business modelling : A case study of a public fast-charging station for electric heavy-duty vehicles in Sweden

    Magister-uppsats, Blekinge Tekniska Högskola/Institutionen för industriell ekonomi

    Författare :Ghaith Arfaoui; Thomas Leffler; [2023]
    Nyckelord :Financial analysis; Business model; Public fast-charging station; Electric heavy-duty vehicles;

    Sammanfattning : Background: Climate changes and global warming call for behaviour changes from mankind and for new business models to introduce sustainable innovations. Financial analysis plays an important role in guiding the choice of these business models. LÄS MER

  7. 5. Techno-economic analysis and design of the charging infrastructure for Electric Heavy Vehicles in Oskarshamn

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Joan Cassany Espinosa; [2023]
    Nyckelord :Electrification; decarbonization; freight transport; heavy duty vehicle; battery electric truck; charging infrastructure; business model assessment; Elektrifiering; avkolning; godstransport; tunga fordon; batterielektrisk lastbil; laddinfrastruktur; affärsmodellsbedömning;

    Sammanfattning : Within the most pollutants industries, the energy sector is the most significant contributor to climate change, representing two-thirds of the total Greenhouse Gas (GHG) emissions. One of the main responsible for these emissions is transportation, which accounts for 26% of the world’s energy consumption, with crude oil-derived products providing more than 90% of this energy.
