  1. 1. DC-DC Converter for Fast Charging with Mobile BESS in a Weak Grid : Enabling remote charging and increased efficiency with less resource intensity

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Alexander Medén; [2023]
    Nyckelord :Battery energy storage systems; Buck-boost; DC DC converter; Dual-active bridge; fast charging; DC charging; Mobile battery systems; Batterienergilagringssystem; Buck-boost; DC DC-omvandlare; Dual-active bridge; snabbladdning; DC-laddning; Mobila batterisystem;

    Sammanfattning : With the increase of electric vehicles (EVs) on the roads the availability of charging infrastructure becomes more important. Today it is relatively straightforward to install fast chargers in areas with strong power grid connections, such as in urban areas. LÄS MER

  3. 2. 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

  4. 3. Design and Evaluation of Heavy Electric Vehicle DC Charging Overcurrent Protection

    Master-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

    Författare :Daniel Buvarp; [2022]
    Nyckelord :DC charging; overcurrent protection; circuit breaker; simulation; semiconductor;

    Sammanfattning : The vehicle industry must reduce emissions to lessen their environmental impact. Using electric motors for propulsion and batteries for energy storage decreases the pollution and greenhouse gases emitted by heavy commercial vehicles such as trucks and buses. LÄS MER

  5. 4. The process of creating an identity : Designing a product series of EV chargers

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Författare :Gustav Hellström; [2022]
    Nyckelord :Design Process; Electric Vehicle Charger; Interaction design; Product Development;

    Sammanfattning : The world is quickly changing and the transition away from fossil fuels is occurring at a rapid pace. The car industry has experienced a radical change in the last years replacing combustion cars with electrical ones. LÄS MER

  7. 5. Techno-economic analysis of retrofitting existing fuel stations with DC fast chargers along with solar PV and energy storage with load flow analysis

    Master-uppsats, KTH/Energiteknik

    Författare :Nilanshu Ghosh; [2020]
    Nyckelord :Electric vehicle charging; DC fast chargers; Load flow analysis; EV charging stations; CIGRE LV networks; Elfordonsladdning; DC-laddare; Lastflödesanalys; EV-laddstationer; CIGRE LV-nätverk;

    Sammanfattning : The increasing number of electric vehicles (EVs) in the transport sector has rendered the conventional fuel-based vehicles obsolete along with the fuel filling stations. With the growth in EVs, there has been an increase in the public charging infrastructure with fast charging equipment being used to charge the EVs in least possible time and also address the issue of ‘range anxiety’ among the EV owners.
