  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. Tekniska lösningar för att hantera laddning av elbussar vid effektbrist : En analys av Uppsalas stadsbussdepå i olika framtidsscenarion

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomi

    Sammanfattning : The city of Uppsala is suffering from power shortage, which is creating issues for Region Uppsala, which manages the new city bus depot. Gamla Uppsala Buss (GUB), the operator of the city busses, has bought 12 electrical busses and is planning to increase that number up to 60, which is a political goal. LÄS MER

  4. 3. Life Cycle Assessment of Electric Road Systems - Climate impact in comparison with battery electric vehicles, biogas vehicles and fuel cell electric vehicles

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystem

    Författare :Ebba Söderström; Emanuel Bengtsson; [2022]
    Nyckelord :Electric road systems; Elonroad; life cycle assessment; rail; feed-in station; pick-up; on-board charger; climate impact; global warming potential; articulated lorry; lower medium car; bus; Technology and Engineering;

    Sammanfattning : One third of Sweden's total annual greenhouse gas emissions originate from the transport sector today and great changes are thus needed in order to reach the net zero emission target by 2045. One of the most important measures discussed is an increased electrification of the transport sector and a solution with potential to contribute to this transition is electric road systems (ERS), where vehicles are charged dynamically.

  5. 4. Optimization of Infrastructure Investment for Decarbonization of Public Buses Through Electricity and Hydrogen : The Case Study of Umeå

    Master-uppsats, KTH/Energiteknik

    Författare :Maria Inês Rocha Jacob; [2022]
    Nyckelord :Electric buses; fuel cell buses; renewable energy sources; green hydrogen; EV charging stations; hydrogen refuelling stations; Sweden; Elbussar; bränslecellsbussar; förnybara energikällor; grön vätgas; laddningsstationer för elfordon; tankstationer för vätgas; Sverige;

    Sammanfattning : Battery electric vehicles and fuel cell vehicles, i.e. hydrogen vehicles, are promising alternatives to internal combustion engine vehicles to reduce GHG emissions from the transport sector. EV charging and hydrogen refuelling infrastructure is crucial to the deployment of alternative fuels in transport. LÄS MER

  7. 5. Elbussar i Örnsköldsvik : En analys över vad som krävs för att elektrifiera bussarna i tätortstrafiken i Örnsköldsvik.

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

    Författare :Max Abrahamsson; [2022]
    Nyckelord :Buss; elbuss; kollektivtrafik; infrastruktur;

    Sammanfattning : For Sweden to achieve its environmental goals by 2045, municipalities need to reducegreenhouse gas emissions, especially from from the transport sector. Recentmeasurements in Örnsköldsvik have shown poor quality air in the built-up environment.Buses are the vehicle classes that emit, proportionally the most carbon dioxide equivalentgases. LÄS MER
