  1. 1. Hardware Subsystem Proposal of an Off-Vehicle Battery Analyzer from a Charging/Discharging Perspective

    Kandidat-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

    Författare :Rinor Gashi; Tim Johansson; [2023]
    Nyckelord :battery electric vehicles; power conversion module; off-vehicle battery packs;

    Sammanfattning : Electric Vehicles (EVs) are seen as one of the solutions to some of the world’s global current problems, such as global warming and air pollution, due to non-existent operational emissions and increased efficiency. There are multiple types of EVs, one of them being Battery Electric Vehicles (BEVs) which in most cases utilizes a Li-Ion battery pack as energy storage. LÄS MER

  3. 2. Towards a setup for narrowband terahertz generation through difference-frequency mixing of chirped ultrashort pulses

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Isa Clementsson; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Terahertz radiation is a useful tool for inducing lower-energy excitations in matter, where it can be used to cause structural changes through direct interaction with the crystal lattice. Sub-picosecond optical pulses can be used to generate intense broadband terahertz pulses through optical rectification in nonlinear crystals, reaching peak electric fields of several MV/m and conversion efficiencies as high as a few percent.

  4. 3. Reducing cost and CO2 emissions in the gasoline to electric vehicle fleet transition

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Emil Grund Stålvinge; [2023]
    Nyckelord :electric car; electric conversion; bldc; li-ion; lion; lipo; li-po; volvo; elbil; elbilar; elkonvertering; bldc; li-ion; lion; lipo; li-po; volvo;

    Sammanfattning : If you buy a new electric car today it will take on average about ten years for you to start saving money compared to just continue driving your old gasoline car. It will also take about 4 years until you start saving carbon dioxide emissions, both of this is because of new production costs and emissions. LÄS MER
