Characterization of Supercapacitors in Thermally Controlled Conditions

This work presents the electrical characterization of commercial supercapacitor cells under controlled thermal conditions. Based on a previously introduced model, the study aims to evaluate the thermal dependence of the model parameters. To this end, a specific software toll was designed and used on a customized test bench. The experimental results obtained in steady-state thermal conditions are then analyzed and compared with those obtained without thermal control, showing how the main parameters of the model vary with the temperature of the cell.
