  1. 1. ANALYS AV HALVLEDARBRYTARE : SIMULERING, MÄTNING OCHBERÄKNING AVVÄRMEUTVECKLING OCH TRANSIENTER

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Erik Nilsson; [2022]
    Nyckelord :;

    Sammanfattning : BAE Systems Hägglunds are using contactors to control the power supply in their vehicle,but a replacer has been developed because the contactors take up a lot of space. The replacer is a self-designed semiconductor switch, which is called Ultra High Power DigitalOutPut or UHPDOP. LÄS MER

  3. 2. Data Logging for Controller Area Network of Autonomous Vehicles : An Investigation of a CAN-Ethernet Gateway

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Daniel Grönås; Fredrik Mazur; [2022]
    Nyckelord :CAN; CAN FD; Ethernet; Gateway; Network; CAN-ETH; CAN-Ethernet; Data Logging; Autonomous Vehicle; CAN; CAN FD; Ethernet; Nätsluss; Nätverk; CAN-ETH; CAN-Ethernet; Dataloggning; Autonoma Fordon;

    Sammanfattning : With the development of autonomous vehicles, more and more technology is introduced into the automotive industry. Ethernet has found its way into the vehicle network, and it is forced to coexist with the well-established CAN bus. LÄS MER

  4. 3. Short-circuit current detection in electric vehicles

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Max Torbjörner; [2022]
    Nyckelord :Electric vehicles; Current measurement; Short-circuit; BEV Trucks; BJB;

    Sammanfattning : In recent years the vehicle industries have been making much efforts to reduce the environmentalimpact by switching from the traditional combustion engine to electrification with battery driven electricvehicles. Producing electric trucks requires more batteries and operates at a higher voltage and currentthan commercial electric cars. LÄS MER

  5. 4. Vägen mot nollutsläpp

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Johan Edholm; [2022]
    Nyckelord :;

    Sammanfattning : The transport sector accounts for one third of Sweden's greenhouse gas emissions. To achieve the goals of Agenda 2030, as well as EU, national, regional, and local goals and contribute to an improved air quality and a better climate, a strategy is needed that shows Örnsköldsvik municipality which vehicles should be given priority to be replaced.

  7. 5. Servicing or Buying New? Estimating the Environmentally Optimal Time for Car Replacement in Sweden – an LCA Approach.

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Larissa Patricia Wissert; [2022]
    Nyckelord :Sustainable Development; Life Cycle Analysis LCA ; Vehicle Replacement; ICEV; BEV; GHG Emissions;

    Sammanfattning : Purpose. Road transportation is one of the major sources of GHG emissions today. Technological improvements in fuel consumption, as well as the electrification of vehicles can reduce emissions from road transportation. This study aims to investigate the optimal time for vehicle replacement in Sweden for an ICEV to minimise GHG emissions. LÄS MER
