  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. 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

  5. 4. Minimising Battery Degradation And Energy Cost For Different User Scenarios In V2G Applications : An Integrated Optimisation Model for BEVs

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Jacob Bengtsson; Benjamin Moberg Safaee; [2023]
    Nyckelord :Vehicle-to-Grid; V2G; Battery Electric Vehicle; BEV; State-of-Charge; SoC; State-of-Health; SoH; charging; discharging; degradation; energy cost; optimisation; optimization; Pyomo; Gurobi;

    Sammanfattning : The functionality to both charge and discharge energy from and to the power grid to a Battery Electric Vehicle (BEV) is referred to as Vehicle-to-Grid (V2G). This allows the customer to buy energy when the spot price is low and sell energy when the price is high to make a profit, called energy arbitrage. LÄS MER

  7. 5. Övervakning av blybatterier under långa transporter

    Master-uppsats, Mälardalens universitet/Innovation och produktrealisering

    Författare :Malin Borgedahl; Elias Sporrong; [2023]
    Nyckelord :BMS; SOC; SOH; IoT; Kvalitet; Blybatteri; Batteriövervakning; Logistik 4.0; Industri 4.0; Transport;

    Sammanfattning : Blybatterier är ett uppladdningsbart batteri som har utvecklats i över 100 år och används i ett brett spektrum där det krävs en långvarig och pålitlig strömkälla. Däremot har blybatterier en begränsad livslängd och kapacitet som styrs av underhållet av batteriet. LÄS MER
