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.
