  5. 3. Ageing in Commercial Li-ion Batteries: Lifetime Testing and Modelling for Electrified Vehicle Applications

    Author : Evelina Wikner; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Battery lifetime tests; Physics-based modelling; Plug-in Hybrid Electric Vehicle PHEV ; Empiric model; Calendar ageing;

    Abstract : In this thesis, ageing in a commercial pouch cell for vehicle application is investigated through lifetime testing and modelling. The lifetime tests investigate the impact of temperature, current, depth of discharge (DOD) and state of charge (SOC). READ MORE

  6. 4. Hybrid digital twins: A co-creation of data science and physics

    Author : Antonio Galvez; Diego Galar; Uday Kumar; Dammika Seneviratne; Dimitrios Kyritsis; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hybrid modelling; physics-based model; data-driven model; HVAC system; Railway; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : Safety is more important than reliability or efficiency in railway, aerospace, oil & gas, and chemical industries. Regulations are very restrictive in sectors where safety is paramount. READ MORE

  7. 5. Limiting processes in anion-exchange membrane fuel cells

    Author : Henrik Grimler; Göran Lindbergh; Rakel Wreland Lindström; Carina Lagergren; Marc Secanell; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; anion-exchange membrane fuel cell; hydrogen oxidation reaction; oxygen reduction reaction; water transport; physics-based modelling; Chemical Engineering; Kemiteknik;

    Abstract : Fuel cells allow for converting chemical energy stored in hydrogen into electrical energy, with only heat and water as by-products. In a sustainable energy society, hydrogen may play an important role due to its ability to act both as an energy carrier and as a valuable chemical in the process industry. READ MORE
