Modeling, Evaluation and Simulation of a Supercapacitor Module for Energy Storage Application

This paper presents the electrical and mathematical model of the supercapacitor.The equivalent mathematical model derived from electrical model was used to simulate the voltage response of the supercapacitor.The model has been implemented using Matlab software program.Simulation and experimental results of the voltage charging/discharging of the supercapacitor are compared.It was found out that the results obtained using the model is in good agreement with the experimental one.Moreover a mathematical model for the efficiency as a function of discharge time was developed and presented.The effect of charge/discharge rate on the supercapacitor's temperature is also experimentally considered.Experiments show that during charging the temperature rises more than during discharging.
