  1. 1. Battery profit optimization

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Ebba Helfer; [2023]
    Nyckelord :Battery; 2nd life battery; Ancillary services; BESS; energy storage system; Technology and Engineering;

    Sammanfattning : In the near future, a new market will form full of 2nd life batteries that are no longer suitable to use in electric vehicles. This since their capacity retention is too low after a few years of usage, as a consequence of two aging mechanisms; cycling aging and calendar aging. LÄS MER

  3. 2. Energy in the Transportation System - A comparison of charging infrastructure scenarios

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Judith Lai Jakobsson; [2023]
    Nyckelord :Charging infrastructure; road transport electrification; battery capacity need; electric vehicles; Technology and Engineering;

    Sammanfattning : A functioning charging infrastructure is crucial for achieving full-scale national electrification within the transport sector. The system is likely to consist of different charging technologies, all with the main objective of providing efficient energy replenishment services. LÄS MER

  4. 3. Benchmarking a 1 kW hybrid hydrogen fuel cell system

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Jonathan Envall; [2023]
    Nyckelord :PEMFC; fuel cell; UAV; hybrid; Technology and Engineering;

    Sammanfattning : Unmanned Aerial Vehicles (UAV's) offer great versatility in the tasks that they may perform and they are today used in many sectors. The H24LEO project, administered by the Lund University School of Aviation, aims to develop and demonstrate a hybrid proton-exchange membrane fuel cell-powered UAV to aid in search and rescue operations performed by the Swedish Maritime Administration, and reduce the greenhouse gas emissions compared to similar work performed by helicopters.

    Master-uppsats, Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

    Författare :Rebecka Ståhl; Parvathy Biju; [2023]
    Nyckelord :Alertness; Circadian Entrainment; Clear Sky; Correlated Colour Temperature; Daylighting; Direct Electric Lighting; Direct-Indirect Electric Lighting; Energy-Efficiency; Grasshopper; Integrative Lighting; LARK 2.0; Melanopic Equivalent Daylight Illuminance; Overcast Sky; Photopic Illuminance; Spectral Power Distribution.; Technology and Engineering;

    Sammanfattning : Human beings in modern society spend more than 90% of their time indoors to live, work, and socialize. To improve health, quality of life and task performance, integrative lighting is designed to give the right light at the right time at the eye to stimulate circadian entrainment. LÄS MER

  7. 5. Electrification and implementation of an uninterruptable power supply system at a medical center in the Talara Province, Peru

    Master-uppsats, KTH/Kemiteknik

    Författare :Johnny Hagelin; [2023]
    Nyckelord :Photovoltaic engineering; Minor Field Study; Energy Resilience; UPS system; Energy poverty; Solcellsteknik; fältstudie; energiresiliens; UPS-system; energifattigdom;

    Sammanfattning : Marginalisering gällande tillgång till elektricitet utgör en betydande utmaning i avlägsna områden i Peru. Elnätets stabilitet är låg och detta utgör ett hot mot viktig infrastruktur såsom sjukhus och vårdcentraler. LÄS MER
