Due to its high power density, long cycle life and clean nature supercapacitors are widely used for improving the dynamic

characteristics of the new and renewable energy sources and extending the battery run-time and life. In this paper improved dynamic

model of the supercapacitor is developed by the electrochemical impedance spectroscopy technique. The developed model can be

used to accurately estimate the dynamic behaviour of the supercapacitor and calculate the exact capacitance value at a certain state

of charges. The model of the supercapacitor in the frequency domain is equivalently transformed into that in the time domain for

Matlab/Simulink simulaton. The simulation data shows fine agreements with experimental results, thereby proving the validity and

the accuracy of the developed model.
