Novel System Identification Techniques For Battery Management System
… we we present a robust approach to estimate the equivalent circuit model (ECM) parameters of a Li-ion battery that offers several advantages over existing ones. Particularly, (i) The proposed approach depends only on measured voltage across and current through the battery; (ii) We theoretically …

Techno-economic modelling and optimization of second life battery packs, with a particular focus on accommodating inhomogeneities and module-to-module variations
… chemistries and establishing a comprehensive modelling framework. Performance characterization is conducted using Hybrid Pulse Power Characterization (HPPC) tests, with a second-order equivalent circuit model (ECM) achieving a maximum error of 2% and an integrated thermal model with a 15% …

In-depth study and analysis of lithium-ion battery states using battery degradation data from electrochemical impedance spectroscopy
… characterization techniques for designing an equivalent circuit model (ECM) of LIB. The thesis highlights the importance of considering the degradation effects into account for different LIB state estimations including state of charge (SOC), state of health (SOH), state of temperature (SOT), …

Characterisation and prediction of state of health of rechargeable batteries
… real-world usage patterns. This has resulted in equivalent circuit models (ECMs) that are over-complicated, and suboptimal battery management systems. It is logical to measure batteries at frequencies reflecting their daily or weekly charge-discharge cycles, i.e., of the order of microhertz. This …
