Abstract
In this contribution we estimate supercapacitor impedance from temporal measurements from two points of view: i) fitting a predefined model to the temporal data and ii) transform time domain analysis to frequency domain to obtain a generalized impedance. A comparison between both methods is provided. In the temporal analyses we started with an a priori model: data was fitted to a three-model parameter. In the frequency domain, we obtained the impedance after temporal data conversion without an i...
