  1. 1. Barriers to blockchain adoption in the public electrical vehicle charging market

    Magister-uppsats, Blekinge Tekniska Högskola/Institutionen för industriell ekonomi

    Författare :Erik Westerström; [2020]
    Nyckelord :blockchain; adoption; public; electrical vehicle; charging; market structure; barriers;

    Sammanfattning : The adoption of blockchain in the public electrical vehicle charging market has yet to be realized to its full potential, despite existing proof-of-concept. A positive outlook for blockchain is suggested by contemporary research, as well as the need for empirical studies to fully identify blockchain’s barriers to adoption. LÄS MER

  2. 2. APPLIKATION AV CYKELLADDNING OMBORD PÅ JÄRNVÄGSFORDON : Konceptutveckling av elcykelladdning ombord på Öresundståget Contessa X31 i samarbete med Bombardier Transportation

    Författare :Olivia Nydestedt; Amanda Sylvan; [2020]
    Nyckelord :elcykel; snabbladdning; utsläpp; elmatning; järnvägsfordon;

    Sammanfattning : There is a great need to reduce the use of fossil-fueled road transport. In order to encourage the use of public transport, opportunities for the application of electrical charging stations for e-bikes aboard railway vehicles were analyzed. LÄS MER

  3. 3. Thermomechanical stress analysis of the main insulation system of traction electrical machines

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik; Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Dahman Ismail; Alexis Andrei; [2020]
    Nyckelord :finite element analysis; thermo-mechanical stress; heavy-duty vehicle; electrical machine; insulation system; coupled-temperature displacement analysis; finita element analys; termomekaniska spänningar; lastbilar; elektriska motorer; isolering; termisk kopplingsförbindelse;

    Sammanfattning : More efficiency heavy-duty vehicles are developed with higher range, updated electronic and mechanical parts. The fuel efficiency and pollution of carbon dioxide need to be lower to achieve new EU regulations. The global population increases with an increased number of heavy-duty vehicles. This, in turn, increases the emission. LÄS MER

  4. 4. Integrating planetary boundaries into the life cycle assessment of electric vehicles : A case study on prioritising impact categories through environmental benchmarking in normalisation and weighting methods when assessing electric heavy-duty vehicles

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Ida Pehrson; [2020]
    Nyckelord :Life Cycle Assessment; Heavy-Duty Vehicles; Electric Vehicle; Normalisation; Weighting; Planetary Boundaries; Livscykelanalys; tunga transporter; elektriska fordon; normalisering; viktning; planetära gränser;

    Sammanfattning : The transport sector is facing great challenges for achieving development within the Earth’s boundaries. Currently, LCA studies on heavy- and medium-duty vehicles have mainly assessed the ‘well-to-wheel’ stage and the impact category climate change. LÄS MER

  5. 5. Treatment of a Liquid Al-Si Alloy : Quality Control and Comparison of Two Melt Degassing Processes

    Magister-uppsats, Jönköping University/JTH, Material och tillverkning

    Författare :Badreddin Radwan; [2020]
    Nyckelord :Dissolved Hydrogen; Degassing; Porosity; Grain Refinement; Eutectic Modification; Fluidity; Metallography; Thermal Analysis.;

    Sammanfattning : Products manufactured by aluminium casting have become very popular and already replaced many parts that were once produced by iron and steel casting. This trends upwards especially in the automotive industry as it has become extremely important to reduce vehicle weight due to environmental requirements and economical aspects. LÄS MER
