  1. 1. Building Distributed Systems for Fresh and Low-latency Data Delivery for Internet of Things

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Adnan Toutounji Alkallas; [2019]
    Keywords : Edge computing; cloud computing; distributed systems; IoT; Age of Information; Edge computing; molntjänster; distribuerade system; sakernas; Age of Information;

    Abstract : Internet of Things (IoT) is a system of interrelated computing devices with the ability to transfer data over the network and collected by the applications that rely on fresh information, where the freshness of data can be measured by a metric called Age of Information (AoI). Age of Information is the time that is measured by the receiving node from the time the data has generated at the source. READ MORE

  2. 2. Lifetime estimation of lithium-ion batteries for stationary energy storage system

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Joakim Andersson; [2017]
    Keywords : Li-ion battery; State of charge; State of health; Kalman filtering; Energy Storage;

    Abstract : With the continuing transition to renewable inherently intermittent energy sources like solar- and wind power, electrical energy storage will become progressively more important to manage energy production and demand. A key technology in this area is Li-ion batteries. READ MORE

  3. 3. Charging time estimation and study of charging behavior for automotive Li-ion battery cells using a Matlab/Simulink model

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Wenzhuo Wu; [2016]
    Keywords : Charging time estimation; HIL; Li-ion battery; Passive balancing; Hardware-in-the-loop; laddtid; litiumjonbatteri; passiv balansering;

    Abstract : An accurate estimation of the charging time of an automotive traction battery is possible only with the knowledge of different parameters of the battery and the vehicle. If this information is not available to the driver, the full time needed for charging of the battery may have to be assessed only from experience. READ MORE

  4. 4. A behavioral model of solar/diesel/Li-ion hybrid power systems for off-grid applications : Simulation over a lifetime of 10 years in constant use

    University essay from KTH/Kraft- och värmeteknologi

    Author : Gordon Gaudray; [2015]
    Keywords : Hybrid power plant; off-grid; renewable; Li-ion battery; dispatching strategy; battery aging; modelling; Matlab; Simulink;

    Abstract : Remote hybrid power systems (RHPS) serve local off-grid loads or various island grids when no grid extension is possible. They combine renewable resources, conventional generators and energy storage systems in order to balance the load at any moment, while ensuring power quality and energy security similar to large centralized grids.

  5. 5. Synthesis of polycarbonate polymer electrolytes for lithium ion batteries and study of additives to raise the ionic conductivity

    University essay from Uppsala universitet/Strukturkemi

    Author : Jonas Andersson; [2015]
    Keywords : battery materials; polymer electrolyte; PTMC; poly trimethylenecarbonate ; LiTFSI; nanofillers; batterimaterial; polymerelektrolyt; PTMC; polytrimetylkarbonat; LiTFSI; nanofillers;

    Abstract : Polymer electrolyte films based on poly(trimethylene carbonate) (PTMC) mixed with LiTFSI salt in different compositions were synthesized and investigated as electrolytes for lithium ion batteries, where the ionic conductivity is the most interesting material property. Electrochemical impedance spectroscopy (EIS) and DSC were used to measure the ionic conductivity and thermal properties, respectively. READ MORE
