  1. 1. Optimization of Thermal Comfort on Electric Buses : A Comprehensive Study on Passenger Satisfaction in Stockholm, Sweden

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Ellinor Hambraeus; Maxwell Minotta Cuervo; [2023]
    Nyckelord :Electric bus; Bus temperature; Thermal comfort; Energy efficiency; Predicted Mean Vote; Equivalent temperature v; Elbuss; busstemperatur; termisk komfort; energieffektivisering; Predicted Mean Vote; Ekvivalent temperatur vii;

    Sammanfattning : The transition towards electrification in the bus sector is necessary to achieve the global climate goals and has gained significant traction in recent years. However, there are critical challenges associated with this transition, one of them being the absence of excess heat that traditional combustion engines provided to warm the bus cabin. LÄS MER

  3. 2. Optimizing the mechanicalpackaging of drivetraincomponents in Formula Studentbattery electric vehicles : Development of electric drivetrains for student engineering competition

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Eric Johansson; [2023]
    Nyckelord :;

    Sammanfattning : The world has seen a rapid increase in the development of electric vehicles. This development is made possible by competent engineers. LÄS MER

  4. 3. Alternative traction system for road-rail vehicles

    Master-uppsats, Lunds universitet/Innovation

    Författare :Jakob Runevad; [2023]
    Nyckelord :Product development; electric traction; construction equipment; road-rail vehicles.; Technology and Engineering;

    Sammanfattning : Excavators have traditionally been diesel driven with hydraulic actuators, but with the ongoing electrification of vehicles, smaller electric excavators are getting more common. Larger electrical excavators are still in a prototyping or early production stage but can be expected to grow. LÄS MER

  5. 4. Integrated DC fast charger in an electric vehicle

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Christoffer Johansson; Axel von Keyserlingk; [2022]
    Nyckelord :Boost converter; DC charging; Electric machine; Inverter; Electric vehicle; Technology and Engineering;

    Sammanfattning : More and more electric vehicles are emerging with a nominal battery voltage higher than what most older DC fast chargers are capable of charging. This requires the vehicle manufacturers to include a high power DC to DC converter in order to be able to charge at these stations, adding cost and complexity. LÄS MER

  7. 5. Heat-pipes in electric machines : Heat management in electric traction motors

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

    Författare :Anton Olofsson; [2022]
    Nyckelord :Heat-pipe; Heat pipe; FEM; LPM; Traction motors; Induction motor; Heat management;

    Sammanfattning : The world is continually changing towards more energy efficient alternatives and less pollution. For the traction market, electric powertrains have become the go-to method, superior to both steam and diesel-electric hybrid systems. LÄS MER
