A method and a system for modelling an ultracapacitor are disclosed. The method involves modelling the ultracapacitor using measured and simulated charge-discharge plots. Measured plots are obtained from a capacitor modelling apparatus that uses one or more constant currents and/or voltages, while simulated plots are generated by a simulation platform using same constant currents and/or voltages values and an initial set of values for capacitors and resistors in a circuit model employing RC ladder-based electrical equivalent circuit model of the ultracapacitor. An optimization process adjusts the initial values of capacitors and resistors in the circuit model to make the simulated plots converge with the measured plots. The final values of capacitors and resistors are determined based on the converged simulated plots, matching the behaviour of the given ultracapacitor, providing an accurate representation of behaviour of the ultracapacitor.
