Theories and models of supercapacitors with recent
The different theoretical models namely empirical model, dissipation transmission line model, continuum model, atomistic model, quantum model, simplified analytical model etc.
A simplified electrical circuit model for a supercapacitor (SC) based on the voltage-current equation is proposed in this paper to address this issue. This model doesn't need an intensive test for accuracy.
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.
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 aim of this study was to demonstrate that the dynamic equivalent circuit can be used to model the behaviour of supercapacitors if one allows for an interpretation in terms of a distribution of relaxation times.
