  1. 1. Storage System for Harvested Energy in IoT Sensors

    Kandidat-uppsats, Högskolan Kristianstad/Fakulteten för naturvetenskap

    Författare :Saif Alhuttaitawi; [2018]
    Nyckelord :Renewable energy; power management; energy harvesting; energy storage; super capacitor;

    Sammanfattning : This work presents an energy system design for wireless sensor networks (WSNs) after applying our design the WSN should theoretically have an infinite lifetime. Energy harvesting sources can provide suitable energy for WSN nodes and reduce their dependence on battery. In this project, an efficient energy harvesting and storage system is proposed. LÄS MER

  3. 2. Determining the voltage range of a carbon-based supercapacitor

    Master-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Thomas Wells; [2014]
    Nyckelord :Carbon electrodes; aqueous electrolytes; sodium sulphate; lithium sulphate; super capacitor; EDLC; electrochemical double layer capacitor; EDL; graphite; nano porous;

    Sammanfattning : The focus of this thesis has been to determine the usable voltage range of carbon-based supercapacitors (SC). Supercapacitors are a relatively new type of capacitors with a vast increase in capacitance compared to capacitors which utilize a dielectric as charge separator. A SC consists of two electrodes and an electrolyte separating the electrodes. LÄS MER

  4. 3. Optimering av hybriddrift för Aurora

    Kandidat-uppsats, KTH/Maskinkonstruktion (Inst.)

    Sammanfattning : Tävlingen Eco Marathon som årligen arrangeras av Shell har som mål att utnyttja studenters innovations- och kreativitet för att ta fram konceptbilar med minsta möjliga bränsleförbrukning. Målet med projektet har varit att ta fram en optimerad hybriddrift för en framtida version av Aurora som tävlar i Urban Concept klassen. LÄS MER

  5. 4. Efficiency Improvements with Super Capacitors in Mechatronic Systems

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Nicklas Sundberg; [2007]
    Nyckelord :Mechatronics; Super capacitor; Regeneration; Energy consulting; Motor control; Mekatronik; Superkondensatorer; Regenerering; Energibesparing; Motorstyrning;

    Sammanfattning : The production industry is getting more and more automated and that implies higher energy consumption. With the increasing awareness of the earth limited resources and the increasing energy prices, energy conservation grows in relevance, both due to cost reduction and environmental benefits. LÄS MER
