It has important effect of decreasing development costs and shortening project development cycle. This paper proposed a supercapacitor model establishment method with the nominal parameter and electrical e-quivalent model as the basic framework, which by using electronic circuit simulation software Pspice, is significant in function and easy to implement. The results show that this model has fine goodness of fit and the deviation of charging voltage curve between time domain simulation and actual measurement is less than 10% during the constant current part. It can fully simulate the supercapacitor equivalent performance and energy storage characteristics to provide the reliable data support for the practical application of various types of supercapacitors.
