    Author : Bojana Petrovic; Ola Eriksson; Marita Wallhagen; Xingxing Zhang; Åsa Wahlström; Högskolan i Gävle; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building; carbon-dioxide equivalent emissions; global warming potential; primary energy use; life cycle assessment; life cycle cost; Byggnad; koldioxidekvivalenta utsläpp; global uppvärmningspotential; pri-märenergianvändning; livscykelbedömning; livscykelkostnad; Hållbar stadsutveckling; Sustainable Urban Development;

    Abstract : The building industry is responsible for 35% of final energy use and 38% of CO2 emissions at a global level. The European Union aims to reduce CO2 emissions in the building industry by up to 90% by the year 2050. Therefore, it is important to consider the environmental impacts buildings have. READ MORE

  5. 13. Methods for Testing and Analyzing Lithium-Ion Battery Cells intended for Heavy-Duty Hybrid Electric Vehicles

    Author : Pontus Svens; Göran Lindbergh; Mårten Behm; Søren Juhl Andreasen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Li-ion; battery; hybrid electric vehicle; Chemical Engineering; Kemiteknik;

    Abstract : Lithium-ion batteries designed for use in heavy-duty hybrid vehicles are continuously improved in terms of performance and longevity, but they still have limitations that need to be considered when developing new hybrid vehicles.               The aim of this thesis has been to study and evaluate potential test and analysis methods suitable for being used in the design process when maximizing lifetime and utilization of batteries in heavy-duty hybrid vehicles.

  6. 14. Development of a Novel Method for Lithium-Ion Battery Testing on Heavy-Duty Vehicles

    Author : Pontus Svens; Mårten Behm; Göran Lindbergh; Per Alvfors; Anders Malmqvist; KTH; []
    Keywords : Lithium-ion battery; HEV; field testing; heavy-duty vehicles;

    Abstract : Increasing demands for lower environmental impact from vehicles, including heavy-duty vehicles, have driven several vehicle manufacturers to consider adding hybrid electrical vehicles (HEV’s) to the product portfolio. Present research on batteries for HEV’s is mainly focused on lithium-ion battery chemistries, since lithium-ion batteries has the most promising technical potential compared to other types of batteries.
