1. 1. Bränder i Elektrifierade Truckar

   Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Cecilia Östholm; [2024]
   Nyckelord :Litium-jon batteri bränder; Elektrifierade truckar; Förebyggande åtgärder; Åtgärder under brand; Litteraturstudie; Intervjustudie.; Technology and Engineering;

   Sammanfattning : The aim of this thesis is to quantify the consequences of a fire in Kalmar Globals Heavy Electric Forklifts and Electric Reachstackers as well as what actions can be taken to reduce the effects of an ongoing fire and what preventing measures can be made by Kalmar Globals customers to create a safe environment and reduce the probability of a fire breaking out. This thesis builds on information gathered during a literature study and a complementary interview study. LÄS MER

3. 2. 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.

4. 3. 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

5. 4. Inductive fast charging of IoT devices : An in-depth analysis of short-range wireless charging technologies based on induction

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

   Författare :Franz Wikner; [2024]
   Nyckelord :Electromagnetic power transfer; Inductive power transfer; Short distance WPT;

   Sammanfattning : In the era of Internet of things (IoT), sensor-equipped devices exchange data over networks. In battery powered IoT devices, the lifespan of the devices is often much longer than the battery life, leading to multiple costly and environmentally hazardous battery replacements during the operational life of the devices.

7. 5. 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.
