  1. 11. NVH analysis and optimization of electric powertrain

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Anujit Dafle; [2022]
    Nyckelord :Electric powertrain; Gear whine; Noise Vibration Harshness NVH ; Elektrisk drivlina; kuggvin; buller och vibrationer;

    Sammanfattning : With increasing focus on electromobility many companies are developing vehicles powered by an electric energy source. Previously, engines used to be the most prominent source of noise in a traditional Internal Combustion Engine (ICE) vehicle. LÄS MER

  3. 12. Optimal Control and Thermal Managementof Heavy-Duty FCHEV Powertrains : Minimizing hydrogen consumption of an FCHEV using numerical optimal control and an integrated energy and thermal management system

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Daniel Similä; Jonatan Siönäs; [2022]
    Nyckelord :Control Engineering; Powertrain Engineering; FCHEV; Optimal Control; Thermal Management;

    Sammanfattning : The CO2 emissions from road vehicles must be reduced in order to avoid a 1.5 ◦C global warming. To reduce tailpipe emissions, a strong trend is to electrify powertrains to shift away from the use of fossil fuel. Among alternatives, the fuel cellhybrid electric vehicle (FCHEV) is seen as a promising configuration. LÄS MER

  4. 13. SAVINGS OF MATERIAL RESOURCES AND CARBON EMISSIONS WHEN CONVERTING FOSSIL FUEL CAR TO ELECTRIC : A CASE STUDY FOR SWEDEN

    Master-uppsats, KTH/Integrated Transport Research Lab, ITRL; KTH/Elkraftteknik

    Författare :Daniel Hiller; [2022]
    Nyckelord :LCA; carbon emissions; material resources; fossil fuel vehicles; battery electric vehicles; carculator; Sweden; LCA; Kohlenstoffemissionen; Materialressourcen; Fahrzeuge mit fossilen Brennstoffen; batterieelektrische Fahrzeuge; carculator; Schweden;

    Sammanfattning : Transportation in Sweden currently accounts for one-third of domestic GHG emissions. Thereof more than 90 % are allocated to road traffic with passenger cars being the largest contributor. Hence, the Swedish government adopted stringent climate policies to cut transport emissionsby 70 % (compared to 2010) latest until 2030. LÄS MER

  5. 14. Capital and Operational Cost Evaluation of Selected Powertrain configurations in Heavy-duty Fuel Cell Trucks

    Master-uppsats, KTH/Fordonsdynamik

    Nyckelord :Heavy long haulage trucks; Total Cost of Ownership TCO ; Fuel Cell Electric Vehicle FCEV ; Battery Electric Vehicle BEV ; Tunga lastbilar; total ägandekostnad TCO ; elfordon med bränsleceller FCEV ; batterielektriska fordon BEV ;

    Sammanfattning : The automotive and heavy-duty trucking industries are heading towards research and development of alternative powertrain solutions to meet the United Nations sustainability goals and cleaner solutions to aid climate change actions. This thesis project aligns with the vision of finding greener and sustainable modes of transport in the heavy long haulage trucking industry. LÄS MER

  7. 15. Experimental Study of Installation Effects on Cooling Fan Noise

    Master-uppsats, KTH/Marcus Wallenberg Laboratoriet MWL

    Författare :Yu-Yu Lu; [2021]
    Nyckelord :Electric vehicles; Cooling fan noise; Installation effects; Free-space measurement; Wall-mounted measurement; In-vehicle measurement; Spectral decomposition method; Tonality; Broadband noise level.;

    Sammanfattning : Owing to the ever-changing developments of battery and electric powertrain, vehicle electrification is the trend in the future. Without the presence of a combustion engine, masking effect from it reduces and noises from other components become perceivable. Among all, the cooling fan is one of the major noise sources. LÄS MER
