  1. 1. State of Health measuring of NiMH batteries using simple electronic components.

    University essay from Linköpings universitet/Fordonssystem

    Author : Linus Classon; [2024]
    Keywords : SoH; NiMH; State of Health; Batteries;

    Abstract : The possibility of measuring the state of health of a NiMH battery without doing it in a lab is evaluated, the goal was to see if it was possible to perceive any differences between batteries of different states of health and whether it’s worth further exploring this solution in a more detailed manner. In order to try and extract and analyze the state of health of the batteries a series of tests consisting of discharging batteries at different lengths of times and different resistive loads were made, the voltage of the batteries being captured by a multimeter.

  3. 2. 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

  4. 3. 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.

  5. 4. 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.

  6. 5. Pre-Study for a Battery Storage for a Kinetic Energy Storage System

    University essay from Uppsala universitet/Elektricitetslära

    Author : Henrik Svensson; [2015]
    Keywords : Batteries; Battery systems; Lithium-Ion; Li-ion; Battery Management Systems; BMS; Flywheel; Batterier; Batterisystem; Litiumjon; li-jon; Battery Management Systems; BMS; Svänghjul;

    Abstract : This bachelor thesis investigates what kind of battery system that is suitable for an electric driveline equipped with a mechanical fly wheel, focusing on a battery with high specific energy capacity. Basic battery theory such as the principle of an electrochemical cell, limitations and C-rate is explained as well as the different major battery systems that are available. READ MORE
