The main obstacle in an Electric Vehicle (EV) is the large torque requirement at the start. And in this case, it must be overcome with a battery that is bigger and heavier. However, a large battery will become a burden when moving and braking. The use of supercapacitors can make the vehicle move more powerful at the beginning of the movement because of its very fast energy release. This paper presents a supercapacitor modeling to support battery performance in an energy storage system. This research is focused on modeling the supercapacitor connected to the drive converter circuit by looking for a mathematical model in the form of a state-space equation, the results of which are simulated using the C Mex S function in Matlab / Simulink. From the modeling carried out, it is obtained a system that has a system response that is built and shows the system is working properly, the output voltage can follow the reference results.
