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

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

    Författare :Gustav Giske; [2022]
    Nyckelord :;

    Sammanfattning : 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.

  3. 2. Investigation of Battery Parameters for Li-ion Battery State of Health Estimation

    Master-uppsats, KTH/Kemiteknik

    Författare :Camilla Söderhielm; [2021]
    Nyckelord :Lithium-ion battery; State of Health; low-temperature ageing; high-temperature ageing; ageing mechanisms; Litiumjonbatteri; hälsotillstånd; lågtemperaturåldring; högtemperaturåldring; åldringsmekanismer;

    Sammanfattning : Miljöpåverkan från konventionella förbränningsmotorer har bidragit till en övergång till elmotorer. I denna övergång spelar litiumjonbatterier en viktig roll som energilagringssystem, men på grund av sin reaktiva kemi kan de utgöra en säkerhetsrisk. LÄS MER

  4. 3. Key Performance Indicators for the monitoring of large-scale battery storage systems

    Master-uppsats, KTH/Energiteknik

    Författare :Emeric Brun; [2019]
    Nyckelord :;

    Sammanfattning : In the context of the fight against climate change, the electricity sector is experiencing a complete renewal. Power grids are undergoing a transformation from centralized and unidirectional systems to multilevel and more integrated networks with, among others, the insertion of intermittent Renewable Energy Sources (RES) on the production side and with the emergence of new consumer behaviors on the demand side.

  5. 4. Low temperature Li-ion battery ageing

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för kemi - Ångström

    Författare :Johan Fredrik Nilsson; [2014]
    Nyckelord :Li-ion battery ageing; Li-ion battery aging; LFP graphite;

    Sammanfattning : Different kinds of batteries suit different applications, and consequently several different chemistries exist. In order to better understand the limitations of low temperature performance, a Li-ion battery chemistry normally intended for room temperature use, graphite-Lithium Iron Phosphate, with 1 M LiPF6 ethylene carbonate:diethylene carbonate electrolyte, is here put under testing at -10°C and compared with room temperature cycling performance.

  7. 5. Correlation between different impedancemeasurement methods for battery cells

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Andreas Blidberg; [2012]
    Nyckelord :Batteries; Li-ion; HPPC; EIS; Hybrid;

    Sammanfattning : Stricter regulations concerning emissions from road traffic and increasing fuel prices has lead to an interest in hybrid electric vehicles (HEVs). Today even manufacturers of heavy duty vehicles are introducing hybrid alternatives. LÄS MER
