  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.

  3. 2. Predicting Lithium-Ion Battery State of Health using Linear Regression

    Kandidat-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Niklas Sundberg; [2024]
    Nyckelord :Lithium-Ion; Multiple Linear Regression; State of Health; Voltage Deviation;

    Sammanfattning : Knowledge of battery health is very important. It provides insight into the capacity of a given system and allows the operators to plan ahead more efficiently. But measuring state of health (SoH) of a battery is difficult, and takes time. More importantly, the battery needs to be taken out of operation to be analysed correctly. LÄS MER

  4. 3. Battery Degradation and Health Monitoring in Lithium-Ion Batteries: An Evaluation of Parameterization and Sensor Fusion Strategies

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Simon Saber; [2024]
    Nyckelord :model-based diagnostics; modellbaserad diagnostik;

    Sammanfattning : The purpose of this project was to perform model-based diagnosis on Li-ion batteries using real-world data and sensor fusion algorithms. The data used in this project was collected and distributed by NASA and mainly consists of voltage and current measurements collected on numerous batteries that were repeatedly charged and discharged from their beginning of life, and until surpassing their end of life.

  5. 4. Hardware Subsystem Proposal of an Off-Vehicle Battery Analyzer from a Charging/Discharging Perspective

    Kandidat-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

    Författare :Rinor Gashi; Tim Johansson; [2023]
    Nyckelord :battery electric vehicles; power conversion module; off-vehicle battery packs;

    Sammanfattning : Electric Vehicles (EVs) are seen as one of the solutions to some of the world’s global current problems, such as global warming and air pollution, due to non-existent operational emissions and increased efficiency. There are multiple types of EVs, one of them being Battery Electric Vehicles (BEVs) which in most cases utilizes a Li-Ion battery pack as energy storage. LÄS MER

  7. 5. Hälsofaktorer och upplevda hälsotillstånd bland elever i Båstad kommun

    M1-uppsats, Malmö universitet/Fakulteten för lärande och samhälle (LS)

    Författare :Kristina Gustafsson; [2023]
    Nyckelord :Barn och unga; Fysisk aktivitet; Hälsa; Idrott och hälsa; Psykisk hälsa; Psykisk ohälsa; Skola Skolstress; Sociala medier; Sociala relationer och Socioekonomiska Förhållanden;

    Sammanfattning : Problem: Barn och ungas psykiska hälsa har fått stor uppmärksamhet, då forskningen tyder på att den blir allt sämre. Forskningen tar upp faktorer som ökad ångest, depression och psykisk obalans bland barn och unga men också ungas brist på fysisk aktivitet samt att användningen av sociala medier har ökat. LÄS MER
