“…Schönleber et al [15] derived the impedance of a LIB electrode from the intercalation reaction of lithium and studied its dependency on SOC, and the results showed that the electrolyte diffusion impedance is independent of the SOC. Huang et al [16] systematically analyzed how different SOCs of 7.5~93.0% can influence battery impedance, and the results indicated that both charge transfer resistance and diffusion resistance increased dramatically when SOC is below 26.5%.…”

“…Simulated battery control strategy development necessitates a plant model representative of real battery behavior. This includes modelling nonlinear dependencies on parameters [1], [2] and a highly dynamic voltage response including a range of time constants spanning several orders of magnitude [2]- [4]. With rapid evolution of cell capabilities, having an easily calibrated model adaptable to different cells is essential for long-term usefulness.…”

“…When using an ECM approach, it is important to consider the underlying causes behind cell resistance. These are complex, being present in both electrodes, electrode surface layers [28], electrolyte [2], [4] and current collectors [29]. These contributions vary significantly in both magnitude and response time to current application [3], [4], and their dependency on usage conditions such as temperature, current and State of Charge (SoC) [1], [4], [21], [30]- [32].…”

“…The EIS provides the frequency-dependent impedance of an electrochemical system by applying a sinusoidal current, measuring the voltage response (galvanostatic EIS) or vice versa (potentiostatic EIS), and applying Ohm's law. The impedance spectra are interpreted regarding their high-frequency inductive behavior [11] caused by geometry, wiring and the test setup, their low-frequency diffusion behavior [12] and mainly their interphase behavior. Numerous studies focus on battery impedance, e.g., correlating aging to changes in the impedance spectrum [13] or explaining the relaxation behavior in graphite anodes [14].…”
