    Sammanfattning : The recent climate actions to reduce greenhouse gas (GHG) emissions have set the stage for decarbonizing the transportation sector through electrification, which has led to a surge in the deployment of battery electric vehicles (BEV). Trucks are no exception, which has led automakers to shift their focus toward producing Battery Electric Trucks (BET). LÄS MER

  5. 19. INFLUENCE OF COOLING METHODS ON THE ENERGY DENSITY OF BATTERIES : Comparing different cooling methods for Lithium-ion batteries

    Uppsats för yrkesexamina på avancerad nivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Oscar Söderberg; Simon Norberg; [2022]
    Nyckelord :Lithium-ion batteries; Battery thermal management system; NCA; Cylindrical battery cell; C-rates; CFD; Energy density.;

    Sammanfattning : Due to climate change, the energy system needs to change from traditional fossil fuels to be dominated by renewable energy sources. Not only the energy system, but the increasing number of vehicles and emissions from the transport sector are a problem for climate change and that need to be solved. LÄS MER
