About Supercapacitors Parameters Determination

Abstract

The parameters determination of the supercapacitors is a required stage in the identification process of the supercapacitors with the applications in which they are integrated. After a short overview of the supercapacitor models, an RC model for a pack of supercapacitors is presented. Between the measurement methods for the supercapacitor parameters, the constant charge method and the capacitance-time domain conversion method are presented. Based on the RC model proposed, parameters determination is made, in a case study that proves the viability of the constant charge method determination.
