“…The first step is the determination of the transfer function in a closed form, which is the ratio of Laplace transforms of the output signal and the input signal. These transfer functions are rational functions of fractional order (see, for example, formula (8)). Then, these transfer functions are modeled using the generalized voltage (E-type) or current (G-type) sources, which are available in the analog behavioral modeling mode.…”

“…Experimental studies show that both the frequency characteristics and transient states in such systems differ from the characteristics and waveforms occurring in classic, integer-order RLC circuits [1,5]. For systems containing supercapacitors, these differences are mainly due to their electrochemical construction [8]. Besides supercapacitors, many new practical realizations of the fractional-order capacitor C α have been developed, among others using the equivalent RC ladder structures, some dielectrics (e.g., LiN 2 H 5 SO 4 ), fractal systems [4,14,27] and many others.…”

Results of analysis of transient states in a series circuit of the class RL β C α , supplied by an ideal voltage source, have been described in the paper. This circuit consists of a coil L β and a supercapacitor C α described by fractional-order differential equations. A method for determining the current and voltage waveforms in the analyzed circuit, based on the decomposition of rational functions into partial fractions, has been described. This method allows to determine transient waveform shapes in the system for any kind of voltage excitation. Two cases of the problem solutions have been considered. The first case concerns a situation where poles of rational functions are real, and the second where rational functions have complex poles. Effective relations enabling the determination of transient waveforms in a closed form have been given. Analytical formulae describing transient state waveforms in the system for different types of voltage excitations: constant, monoharmonic, periodic and arbitrary being an element of a Hilbert space, have been determined, too. The obtained results have been illustrated by an example.

“…However, the accuracy of this method is highly dependent on the measurement precision so it is sensitive to measurement noise. Gualous et al [26] used electrochemical impedance spectroscopy (EIS) to characterize a second-order equivalent circuit model for UCs. EIS is a commonly used approach for the measurement of the complex impedances of energy storage devices such as batteries and UCs.…”

Online Parameter Identification of Ultracapacitor Models Using the Extended Kalman Filter

et al. 2014

Ultracapacitors (UCs) are the focus of increasing attention in electric vehicle and renewable energy system applications due to their excellent performance in terms of power density, efficiency, and lifespan. Modeling and parameterization of UCs play an important role in model-based regulation and management for a reliable and safe operation. In this paper, an equivalent circuit model template composed of a bulk capacitor, a second-order capacitance-resistance network, and a series resistance, is employed to represent the dynamics of UCs. The extended Kalman Filter is then used to recursively estimate the model parameters in the Dynamic Stress Test (DST) on a specially established test rig. The DST loading profile is able to emulate the practical power sinking and sourcing of UCs in electric vehicles. In order to examine the accuracy of the identified model, a Hybrid Pulse Power Characterization test is carried out. The validation result demonstrates that the recursively calibrated model can precisely delineate the dynamic voltage behavior of UCs under the discrepant loading condition, and the online identification approach is thus capable of extracting the model parameters in a credible and robust manner.

In this paper, criteria for better selection of a supercapacitor through EIS (Electrochemical Impedance Spectroscopy) experiments are presented. The performance characteristics of a supercapacitor are thoroughly analyzed in terms of losses and available energy to select the optimal product. The validity of the proposed criteria is demonstrated through the computer simulations and experiments on a fuel cell vehicle using a supercapacitor module with the FTP-72 urban dynamometer driving schedule.
