【Abstract】 In the application of an electrochemical supercapacitor,a model to simulate its characteristics is established,and to measure the parameters is an important aspect.A model of equivalent circuit is presented with two RC branches for tractive carbonsupercapacitor,and the procedure and methodology to determinate the model parameters are probed.As an example,a supercapacitor with nominal electrostatic capacitance of 0.5MF was measured by the constantcurrent chargedischarge cycle,and the model parameters were determined.The results show that the simulation model of supercapacitor and the procedure of parameters determination are valid.更多还原
