The determination of the equivalent parameters of a supercapacitor requires the galvanostatic measurement of a charge and self-discharge cycle.

Abstract
The determination of the equivalent parameters of a supercapacitor requires the galvanostatic measurement of a charge and self-discharge cycle. If a more general determination is needed than that on the single cycle, it is necessary to take into account the repeatability of the charging and self-discharging cycles. A cycle for determining the parameters can also extend over a few hours for larger supercapacitors, also considering the time needed to identify the parameters. Therefore, having a large set of dozens of cycles including the parameters determination is definitely a time-consuming procedure. In this work, an efficient method for the repeatability assessment of the equivalent circuit parameters is proposed; this approach relies on a limited set of experimental curves and on a single parameter identification process.File | Dimensione | Formato | |
