  1. 1. 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.

  3. 2. State of Health estimation of battery systems

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Carl Spångberg; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This study focuses on estimating the state of health (SoH) of a lithium iron phosphate (LFP) battery system, which is crucial for assessing the value and lifespan of new or used batteries in energy storage, grid support, and electric vehicle applications. A proposed method for determining SoH based on comparing useful and nominal useful capacities in Ah and Wh, as well as total and nominal capacity, has been presented. LÄS MER

  4. 3. Korttidsprognoser av Kalixälvens vattenflöde

    Kandidat-uppsats, Lunds universitet/Statistiska institutionen

    Författare :Mathilda Carlsson; [2023]
    Nyckelord :ARIMA; RecursiveAR; forgetting factor; sliding window; Kalman filter; short-term predictions; water flows; Mathematics and Statistics;

    Sammanfattning : The Kalix River, located in the northern part of Sweden, experiences a slowdown in water flow during cold winters. However, in spring, when snow and ice melt in the mountains, the water flow starts to increase. Towards the end of spring, there is usually a rapid and unpredictable surge in water flow known as the spring flood. LÄS MER

  5. 4. Benchmarking VisualInertial Odometry Filterbased Methods for Vehicles

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Muhammad Zahid; [2021]
    Nyckelord :visual inertial odometry; VIO; sensor fusion; state estimation; recursive filter; navigation; autonomous vehicles; visuell tröghetsodometri; VIO; sensorfusion; tillståndsuppskattning; rekursivt filter; navigering; autonoma fordon;

    Sammanfattning : Autonomous navigation has the opportunity to make roads safer and help perform search and rescue missions by reducing human error. Odometry methods are essential to allow for autonomous navigation because they estimate how the robot will move based on the available sensors. LÄS MER

  7. 5. Simulation of Mechanical Shock with Finite Element Analysis and Estimation of Shock Attenuation

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Cheng Qian; [2021]
    Nyckelord :shock; SRS; FEA; attenuation; chock; SRS; FEA; chockdämpning;

    Sammanfattning : Space equipment is often subjected to mechanical shocks. Some devices like electronics are sensitive to shocks, and they can easily be damaged. To protect these devices, it is important to study shock penetrations in space structures. The Finite Element Method is an effective tool to simulate response to transient excitations. LÄS MER
