  1. 26. Power-to-Gas and zero-emission buses in Uppsala : challenges and Opportunities from a techno-economic perspective

    University essay from SLU/Dept. of Energy and Technology

    Author : Mårten Rosell; [2021]
    Keywords : Power-to-gas; bränsleceller; medicinsk syrgas; modellering; lönsamhet;

    Abstract : This thesis has explored the use of power-to-gas technology as a means to produce hydrogen for fuel cell electric buses. The municipal council of Uppsala are looking at options to electrify the local city and regional bus fleet but have been faced with power capacity constraints on the local electrical grid. READ MORE

  3. 27. Smart Charging and Electric Vehicle Grid Integration

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Pradeep Vanamala; Andreas Blom; [2021]
    Keywords : ;

    Abstract : Electric vehicles (EV) in the transportation sector will play a major role in achieving low-carbon emissions from the mobility of vehicles. With a future increase in electric vehicles and autonomous electric vehicles, the demand for charging increases and this comes with new problems that require modern solutions. READ MORE

  4. 28. Braking with a Directional Control Valve in a Hydraulic Open-Loop Transmission

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : Jonathan Karlborg; Emil Sten; [2021]
    Keywords : Directional Control Valve DCV ; Open-loop Hydraulic Transmission; Brake function;

    Abstract : This project presents an investigation if natural braking characteristics could be achieved on an open-loop hydraulic transmission without a brake valve. The goal with the simplified system was to utilize the directional control valve to achieve similar functionality as the brake valve does in the conventional system. READ MORE

  5. 29. Active and semi-active suspensions for articulated vehicles to minimise tyre wear

    University essay from KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Author : Haoran Zhang; [2021]
    Keywords : Articulated vehicle; tyre wear; quarter car model; semi-active and active suspension; Ledat fordon; däckslitage; kvartsbilsmodell; semiaktiv och aktiv fjädring;

    Abstract : Tyre wear is a vital problem in vehicles, especially in articulated vehicles because of their heavier axle loads. Tyre wear can not only do harm to vehicle dynamics but also cause tyre particle emissions. Therefore, solutions that can minimise tyre wear are where this thesis work focuses. READ MORE

  6. 30. Enhancement of evaluation method of journal bearings’ performance in heavy-duty diesel engines

    University essay from KTH/Skolan för industriell teknik och management (ITM)
