WeD-3-5 Modeling of Lithium-Ion Capacitor and its Charging and Discharging Circuit in Model Based Design Approach

Abstract

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.
