  1. 1. Physics-Based Modelling for SEI and Lithium Plating During Calendar and Cycling Ageing

    University essay from KTH/Kemiteknik

    Author : Oskar Nordlander; [2022]
    Keywords : Lithium-ion Battery; Calendar Ageing; Cycling Ageing; Battery Degradation; Physics-Based Modelling; SEI; Lithium Plating; Litium-jonbatterier; Kalenderåldring; Cykling åldrande; Batteriåldrande; Fysikbaserad Modellering; SEI; Litium Plätering;

    Abstract : Målet med projektet var att undersöka samt implementera en fysikbaserad DFN modell för att simulera kalender samt cyklingåldrande av litiumbatterier som används i elbilar. Den fysikbaserade modellen var konstruerad baserad på ett Python biblioteket vid namn PyBaMM, vilket till skillnad från datadrivna modeller ger essentiell information om de kemiska processerna inuti batteriet.

  4. 3. Ageing of NCA/Graphite-Silicon Cells : Investigating the feasibility of accelerated ageing

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Gustav Giske; [2022]
    Keywords : ;

    Abstract : Reliable test data on cell ageing is important to have when deciding on which cell to use in a vehicle. Accelerated ageing could, if performed in a good way, increase the amount of information about the cell ageing in an early stage of a vehicle project, reducing the risk of costly battery replacements.

  5. 4. Thermo-mechanical Fatigue of Electrical Insulation System in Electrical machine

    University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

    Author : Ahmed Elschich; [2017]
    Keywords : Thermal mechanical fatigue; Thermo-mechanical stress; electrical machine windings; electrical insulation system; slot insulation; slot liner; groundwall insulation; conductor insulation; turn insulation; stator;

    Abstract : Electrical machines in electrified heavy-duty vehicles are subjected to dynamic temperature loadings during normal operation due to the different driving conditions. The Electrical Insulation System (EIS) in a stator winding is aged as an effect of these dynamic thermal loads. READ MORE

  6. 5. Finite Element Modeling of an Innovative Headband : A study about the headband design and its safety properties

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Giuliana Mozzi; [2017]
    Keywords : finite element; FEM; headband; innovative; modeling; safety;

    Abstract : One of the most recent challenges faced worldwide is the so-called “ageing population” phenomenon. Besides the disabilities and illnesses that the elderly is prone to, traumatic brain injuries represent a common and potentially fatal factor that greatly affects this population. READ MORE
