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

    Kandidat-uppsats, Linköpings universitet/Fordonssystem

    Författare :Linus Classon; [2024]
    Nyckelord :SoH; NiMH; State of Health; Batteries;

    Sammanfattning : 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.

    Sammanfattning : Följande studie är utförd på uppdrag av företaget Nilar som tillverkar Nickel-Metallhydridbatterier (NiMH-batterier) vid sin produktionanläggning i Gävle. Den nuvarande beräkningen av State of Charge (SoC) sker på deras Battery Management Unit (BMU) och är implementerad i Structured Text i exekveringsmiljön CODESYS. LÄS MER

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

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Oorganisk kemi

    Författare :Lovisa Niklasson; [2018]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

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

    Sammanfattning : 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.
