  1. 6. Suppression of Li-ion Battery Fires

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Linfan Cai; [2023]
    Nyckelord :Lithium-ion Battery; Fire Suppression System; Extinguishing Agent; Thermal Runaway; Battery Energy Storage System; Electric Vehicle; Technology and Engineering;

    Sammanfattning : This thesis presents a systematic literature review of fixed fire suppression systems and extinguishing agents for lithium-ion battery (LIB) fires. The review identifies 85 relevant sources published between 2013 and March 2023, and categorises different research experiments into cell-level, module-level, electric vehicle (EV) pack-level, battery energy storage system (BESS) rack-level and warehouse storage experiments, according to LIB configurations.

  3. 7. Hur förhåller sig svenska rederier till avsaknaden av ett regelverk för transport av elbilar som ro-ro last

    Uppsats för yrkesexamina på grundnivå, Linnéuniversitetet/Sjöfartshögskolan (SJÖ)

    Författare :Philip Brehmer; Hjalmar Boestad; [2023]
    Nyckelord :Ro-ro Ro-pax Lithium-ion battery Thermal runway; Ro-ro Ro-pax Litiumjonbatteri Termisk rusning;

    Sammanfattning : Syftet med denna studie är att forska i hur olika rederier och besättningar förhåller sig till avsaknaden av regelverk gällande transport av fordon med litiumjonbatterier. Tidigare forskning visar att bränder i litiumjonbatterier skiljer sig från bränder i konventionella bilar då det finns risk för att termisk rusning initieras i cellerna vilket medför att återantändningsrisken är stor och branden svårsläckt med begränsade mängder vatten.
