One of the problems in putting Electric Vehicles into practical use is the insufficiency of charging and discharging performances of conventional battery. A promising solution for this problem is the hybrid energy storage system (HESS) consisting of capacitor and battery. For its model based design (MBD) and simulation, a precise modeling of capacitor is necessary. We proposed a Lithium-Ion Capacitor (LIC) model with three elements including a variable capacitor. The accurate correspondences are recognized and it is proven that the proposed model of LIC can be used in MBD method.
