  1. 1. Techno-economic analysis of commercial battery storage systems in Northern Europe

    University essay from Uppsala universitet/Elektricitetslära

    Author : Albert Bergström; [2020]
    Keywords : ;

    Abstract : As the world looks to lower its need for fossil fuels, photovoltaics has been put forward as one of the proposed solutions. There is, however, one major drawback with the electricity production coming from photovoltaics – it is intermittent and rarely matches the electricity demand profile of society. READ MORE

  3. 2. Power peak reduction and control of automatic sliding doors

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Nicklas Norborg Persson; Per Josefsson; [2019]
    Keywords : Technology and Engineering;

    Abstract : When a sliding door is opened there is a sudden current peak that the electric network is subjected to. As a result of this it is difficult to design a power supply that operates the door with adequate performance while still maintaining a low power rating. READ MORE

  4. 3. Characterization of the gas composition inside NiMH batteries during charge using GC-MS

    University essay from Uppsala universitet/Oorganisk kemi

    Author : Lovisa Niklasson; [2018]
    Keywords : NiMH batteries; Batteries; Nickel-metal hydride; Nickel hydroxide; Metalhydride; Gas evolution; Oxygen; Hydrogen; Electochemistry; Gas Chromatography; NiMH-batterier; Batterier; Nickel-metalhydrid; Nickelhydroxid; Metalhydride; Gasutveckling; Syrgas; Vätgas; Elektrokemi; Gaskromatografi;

    Abstract : The aim of the project was to develop a method to measure and studythe degree of activation of the negative electrode (MH) in a NiMH battery.This was done by characterization of the gases produced during charge of a battery – O2 and H2 – using a Gas Chromatograph. READ MORE

  5. 4. Failure Prediction of NiMH Batteries

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Markus Hägnefelt; Filip Dahlberg; [2018]
    Keywords : Technology and Engineering;

    Abstract : This master thesis has been carried out to investigate the possibility to predict battery failure of Nickel-Metal Hydride (NiMH) batteries. Assa Abloy use these batteries as a back-up in their door solution systems in case there is a power loss. The main function is to be able to open doors that are part of an emergency exit route.

  6. 5. Recovery of valuable metals from spent HEV NiMH battery leach solutions

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Jonas Ricknell; [2017]
    Keywords : Recycling; Hydrometallurgy; NiMH; Supported liquid membrane; Mixed metal hydroxide;

    Abstract : As the demand on resources is increasing worldwide, the process of recycling material has become more important. The specific recycling of metals used in car batteries, and more specifically in the large batteries used in hybrid electric vehicles, is a rising concern where the industrially implemented recycling processes concerning these batteries that exist today are often highly pollutant and energy consuming.
