Abstract:

The paper concerns the beginning of a modeling study for supercapacitors. A data acquisition (DAQ) based system is presented, where an automated procedure has been implemented for the measurement of frequency characteristics. For a typical range of the supply voltage the characteristics are obtained. A model basing on fractional calculus is recalled and parameters for the model are obtained. The frequency characteristics of the model are compared with those obtained from measurements. Later the tested supercapacitor has its characteristics taken for various amplitudes and offsets of the source voltage. A few remarks are given for a possible expansion of the model when nonlinearity should be considered.
