Experimental design for an enhanced parametric modeling of supercapacitor equivalent circuit model

The modelling of the supercapacitor (SC) plays an important role for industrial application with many model representations such as electrical, chemical, and electrochemical models. Among one those models are equivalent circuit which has been used to describe real-time (charging/discharging) operation characteristics SC. Apart its mathematical complexity, time-consuming experimentally is also a real challenge obtaining internal parameters values Choices test equipment structure design experiment play criteria affect accuracy model. This research emphasis on structured experimental SC by using Neware battery tester. exercise attain described discussed in paper. findings were benchmarked empirical previous researchers. terminal voltage was validated via maximum relative error 0.045%. successfully reproduce dynamic behavior during charge/discharge phase indicates proposed method accuracy.
