  5. 9. Assessment of safety characteristics for Li-ion battery cells by abuse testing

    Författare :Carl Fredrik Larsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; overcharge; Lithium-ion; toxic gases; abuse test; thermal runaway; short circuit; safety; battery; fire;

    Sammanfattning : Despite the many advantages with lithium-ion batteries there can be disadvantages in form of safetyissues. In an abuse situation a Li-ion cell can undergo a thermal runaway releasing excessive heat,flammable and toxic gas emissions and eventually accompanied by dissembling/explosion and fire. LÄS MER

  7. 10. Identifying Parameters for Aging-Adaptive Battery Management

    Författare :Moritz Streb; Göran Lindbergh; Matilda Klett; Kandler Smith; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium-ion battery; Parameter estimation; Aging-adaptive usage; Electrochemical battery management; Litiumjonbatteri; Parameteruppskattning; Åldringsmedveten användning; Elektrokemisk batterikontroll; Chemical Engineering; Kemiteknik;

    Sammanfattning : The modern transportation system is largely based on fossil fuels. To reduce this reliance on oil and gas and thereby drastically reduce emissions, a transition to renewable power sources is necessary. Lithium-ion batteries are the most established candidate for electromobility applications, with suitable energy and power densities. LÄS MER
