How to model a supercapacitor?

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.

Can a simplified electrical circuit model be used for a supercapacitor?

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.

How to provide the parameters of a supercapacitor equivalent circuit?

The experimental method to provide the parameters of the supercapacitor equivalent circuit is described. Based on the proposed method, the supercapacitor model is built in Matlab/ Simulink, and the characteristics of equivalent series resistance (ESR) measurement and cycle life are compared with datasheets.

Can a simplified supercapacitor model be used for short-term energy storage?

The proposed simplified supercapacitor model requires minimal testing to derive parameters from datasheets. This model effectively simulates supercapacitor behavior for short-term energy storage in power applications. Equivalent series resistance (ESR) and cycle life characteristics align well with datasheet data.
