  1. 1. Bränder i Elektrifierade Truckar

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Cecilia Östholm; [2024]
    Nyckelord :Litium-jon batteri bränder; Elektrifierade truckar; Förebyggande åtgärder; Åtgärder under brand; Litteraturstudie; Intervjustudie.; Technology and Engineering;

    Sammanfattning : The aim of this thesis is to quantify the consequences of a fire in Kalmar Globals Heavy Electric Forklifts and Electric Reachstackers as well as what actions can be taken to reduce the effects of an ongoing fire and what preventing measures can be made by Kalmar Globals customers to create a safe environment and reduce the probability of a fire breaking out. This thesis builds on information gathered during a literature study and a complementary interview study. LÄS MER

  3. 2. Aerodynamics simulations of Scania trucks using OpenFOAM

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Ziyi Liu; [2024]
    Nyckelord :Heavy-duty truck; Computational fluid dynamics; Air drag; OpenFOAM;

    Sammanfattning : In the field of heavy-duty vehicles, fuel efficiency and environmental protection are factors that need to be focused on, while the aerodynamic drag generated during vehicle travelling is one of the most influential aspects. This thesis delves into the aerodynamic simulation of Scania trucks using the open-source Computational Fluid Dynamics (CFD) tool, OpenFOAM v2206. LÄS MER

  4. 3. Powering the Future: Unveiling the challenges associated with planning of charging infrastructure for heavy electric vehicles - A master thesis on the future planning of heavy charge infrastructure in Sweden

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Hassan Abbas Cheema; Robin Holmgren; [2023-11-01]
    Nyckelord :heavy charge infrastructure;

    Sammanfattning : The transport sector is currently transitioning into a more sustainable use of fuel. The current aim of the European Commission is to reduce the greenhouse gas net emissions by 55% by 2030 compared to 1990 levels. Electric trucks are considered an important aspect in this transition.

  5. 4. Dynamic axel load estimation for an electrified vehicle : Normalkraftestimering på drivaxeln

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Majd Barakat; [2023]
    Nyckelord :Vehicle dynamics; Suspension systems; Vehicle design; Bounce-Pitch model; Car quarter model; Normal force; Normal force estimation;

    Sammanfattning : The brake system is critical for ensuring safe driving and has been the focus of development for many years. Pneumatic braking technology is commonly used in heavy vehicles,but it results in energy wastage and high service costs. Some countries mandate auxiliarybraking systems to assist in stopping the vehicle in addition to service brakes. LÄS MER

  7. 5. 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
