  4. 3. Nanocellulose and Polypyrrole Composites for Electrical Energy Storage

    Författare :Gustav Nyström; Maria Strömme; Leif Nyholm; Petr Novák; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; conducting polymer; polypyrrole; cellulose; nanocellulose; porosity; composite; energy storage; battery; supercapacitor; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Sammanfattning : To meet the predicted increase in demand for energy storage in tomorrow's society, the development of inexpensive, flexible, lightweight and sustainable energy-storage materials is essential. In this respect, devices based on electroactive organic molecules, such as conducting polymers, are highly interesting. LÄS MER

  5. 4. Optimal Energy Scheduling of Grid-connected Microgrids with Battery Energy Storage

    Författare :Kyriaki Antoniadou-Plytaria; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy management; Battery energy storage; distribution network; optimization; energy scheduling; microgrids;

    Sammanfattning : The coupling of small-scale renewable-based energy sources, such as photovoltaic systems, with residential battery energy storages forms clusters of local energy resources and customers, which can be represented as controllable entities to the main distribution grid. The operation of these clusters is similar to that of grid-connected microgrids. LÄS MER

  7. 5. Data-driven lead-acid battery lifetime prognostics

    Författare :Sergii Voronov; Erik Frisk; Mattias Krysander; Jonas Biteus; Thorsteinn Rögnvaldsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : To efficiently transport goods by heavy-duty trucks, it is important that vehicles have a high degree of availability and in particular avoid becoming standing by the road unable to continue the transport mission. An unplanned stop by the road does not only cost due to the delay in delivery, but can also lead to a damaged cargo. LÄS MER
