  1. 1. 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

  3. 2. 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.

  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. Migrering av en State of Charge-algoritm : Migrering och optimering av State of Charge algoritmen för Nickel-metallhydridbatterier

    M1-uppsats, Högskolan i Gävle/Avdelningen för datavetenskap och samhällsbyggnad

    Författare :Christoffer Jansson; Malte Pettersson; [2023]
    Nyckelord :State of Charge; Battery Management System; Nickel-metal hydride battery; Migration; Optimization; Execution time; C; CODESYS; LU Factorization; State of Charge; Battery Management System; Nickel-Metallhydridbatteri; Migrering; Optimering; Exekveringstid; C; CODESYS; LU-faktorisering;

    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
