EDLC ModelThis page provides Matlab codes and experimental data described in the paper. The codes are given in the zip file below. Download and save the PDF files as m files to use them. Note that running the same codes in FORTRAN or C++ may be more faster or efficient. The estimation algorithm used may not converge or provide global optima for all the problems. Supercapacitors have a very high power density, which allows them to be charged and discharged in applications that occur on the order of seconds, for example, in regenerative braking in hybrid electric vehicles. vCell.m is a function file of the capacitor model used. It inputs a parameter vector and a time vector and returns the predicted discharge of the capacitor. Vres.m is a function file which calculates and returns the difference between the model predicted curve (from vCell.m) and the experimental data. The m-files are posted as a single pdf file titled EDLC_Simulation.pdf in the zip file below. TempTime.txt is a vector of the experimental times that data is measured. Note that it resets to zero at each experimental step. TempVolt.txt is a vector of experimentally measured voltages. TempStep.txt records the condition under which of each data point was sampled (charge, discharge, or relaxation), while TempNumber.txt lists the cycle numbers.
