Abstract
Thepaperpresentsaproposalofusingadditionalstatisticalparameterssuchas:standarddeviation,variance, maximum and minimum increases of the observed value that were determined during measurements of temperature fields created on the surface of the tested electrochemical capacitor. The measurements were carriedoutusingthermographicmethodsinordertosupportassessmentoftheconditionofelectrochemical capacitorunderclassicdurabilitytestsbasedonmethodsofdeterminationofcapacityandequivalentseries resistance.Thepossibilityofusingsomestatisticalparametersinassessmentoftheelectrochemicalcapacitor quality was illustrated. The applied measurement methodology and the results of research associated with the classic methods of supercapacitors’ assessment are presented. The obtained results indicate that the variabilityofsomestatisticalparametersoftemperaturefieldscanbedirectlyrelatedtochangingthevalues of standard parameters describing electrochemical capacitor, which are capacitance and equivalent series resistance.
