In this doctoral thesis, the author focuses on advancing the modeling and design of observers for lithium-ion batteries (LiBs). LiBs play a critical role in the transition to renewable energy and vehicle electrification, but they still present challenges in terms of performance, safety and management. The author develops a multi-particle model with electrolyte dynamics (MPMe) to better represent the behavior of LiBs. Additionally, state observers are designed to estimate the lithium concentration in the electrolyte and the solid lithium concentration. These observers are validated using simulations, demonstrating their effectiveness in real-time monitoring of LiBs. This research aims to improve the performance, safety and reliability of LiBs, thereby contributing to wider adoption of electric vehicles and sustainable electrification of the transport sector.
