Here, it is shown that consistent modelling of a supercapacitor can be done in a straightforward manner by introducing a dynamic equivalent circuit model that naturally allows a large number or a continuous distribution of time constants, both in time and frequency domains.
The paper reviews the modelling techniques like Empirical modelling, Dissipation transmission line models, Continuum models, Atomistic models, Quantum models, Simplified analytical models etc. proposed for the theoretical study of Supercapacitors and discusses their limitations in studying all the aspects of Supercapacitors.
Several models have been proposed in literature to model the supercapacitors, aiming to maximize the model accuracy in the whole frequency spectrum. However, their real-time modeling has been not deeply studied, in particular, considering the real-time simulation constraints, that limit either the model details or the simulation size.
The simulation results have verified that the proposed model can be applied to simulate the behaviour of the supercapacitor in most energy and power applications for a short time of energy storage. A supercapacitor test circuit is given to test the charge and discharge of supercapacitor modules.
Distribution of relaxation times provides an indicator of charge dynamics at the electrodes. Both time dynamics (charging and self-discharging) and impedance spectroscopy can be studied within the model. Supercapacitors are often modelled using electrical equivalent circuits with a limited number of branches.
Among the many models of supercapacitors, the most widely used is the equivalent circuit model. The equivalent circuit model, according to the electrical characteristics of the supercapacitor in the working process, uses various components in the circuit to characterize its internal deterioration mechanism.
