  1. 26. 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

  3. 27. Design and Evaluation of Heavy Electric Vehicle DC Charging Overcurrent Protection

    Master-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

    Författare :Daniel Buvarp; [2022]
    Nyckelord :DC charging; overcurrent protection; circuit breaker; simulation; semiconductor;

    Sammanfattning : The vehicle industry must reduce emissions to lessen their environmental impact. Using electric motors for propulsion and batteries for energy storage decreases the pollution and greenhouse gases emitted by heavy commercial vehicles such as trucks and buses. LÄS MER

  4. 28. Hydroacoustic Modelling of Podded Propulsion System : Underwater Radiated Noise Prediction Using ANSYS

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Martin Persson; [2022]
    Nyckelord :Fluid Mechanics; Computational Aeroacoustics; Frequency Response; Noise and Vibration; Pod; Propulsion System; ANSYS; Reynolds-Averaged Navier-Stokes Equations; Kongsberg Maritime Sweden AB;

    Sammanfattning : Ocean noise pollution is an invisible but growing threat. There are many sources of sound in the ocean but human underwater radiated noise, in particular from shipping is one of the most prominent one. Ocean noise pollution can interfere or sometimes even directly harm marine life. LÄS MER

  5. 29. Electric Propulsion for a High Altitude Unmanned Aerial Vehicle

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

    Författare :Jacob Hjort Friderichsen; David Jönsson; [2022]
    Nyckelord :Electric Propulsion; UAV; ALPHA; Electronic Speed Controller; BLDC Motor; Propeller;

    Sammanfattning : The catalogue of observational platforms for space and atmospheric research can be expanded by utilising drones equipped with specialised instrumentation and capable of flying at high altitudes. In this project the requirements for an electric propulsion system applicable to the KTH Royal Institute of Technology ALPHA project are evaluated. LÄS MER

  7. 30. Batteridrift på mindre fartyg : Klimatnyttigt eller inte?

    M1-uppsats, Linnéuniversitetet/Sjöfartshögskolan (SJÖ)

    Författare :Erik Nordborg; Amadeus Ide; [2022]
    Nyckelord :electrification; emissions from carbon dioxide; production of batteries; electric power; diesel power; ships; elektrifiering; Koldioxidutsläpp; batteriframställning; eldrift; dieseldrift; fartyg;

    Sammanfattning : De europeiska klimatmålen gällande utsläpp av växthusgaser blir allt tuffare, och man börjar tänka i banorna att elektrifiera sina fordon och fartyg. Detta innebär en mer omfattande batteridrift och produktion av litium-jon batterier. LÄS MER
