  1. 1. Mäta HRR från Li-jonbatterier med hjälp av OCC (oxygen consumption calometry) och andra metoder

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Olof Skyllberg; [2023]
    Nyckelord :Litium-jon batteri; Termisk rusning; Oxygen consumption calorimetry OCC ; Sensible enthalpy rise approach SERA ; effektutveckling. Lithium-ion batteries; Thermal runaway; Heat release rate.; Technology and Engineering;

    Sammanfattning : One of the most important parameters to measure in the fire discipline is the heat release rate (HRR). Therefore it is very important that these measurements are accurate and as correct as possible. The most common method for measuring heat release rate of fires is the OCC method (oxygen consumption calorimetry). LÄS MER

  3. 2. Modeling of Battery Degradation in Electrified Vehicles

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Olof Juhlin; [2016]
    Nyckelord :Li-Ion batteries; State of Health; Electrified vehicles; Battery degradation; EV; BEV; PHEV;

    Sammanfattning : This thesis provides an insight into battery modeling in electric vehicles which includes degradation mechanisms as in automotive operation in electric vehicles. As electric vehicles with lithium ion batteries increase in popularity there is an increased need to study and model the capacity losses in such batteries. LÄS MER

  4. 3. Grid Capacity Issues with Distributed Generation

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

    Författare :Nofel Dakhel; Olof Bohgard; [2014]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Climate change is more evident than ever as reflected in The European union's environmental directives which say that the carbon emission must be reduced by 20% and 20% of the used energy must come from renewable energy sources until 2020. In Germany political decision has been made that the nuclear power will be replaced by renewable energy in long term. LÄS MER
