Method of Identifying the Electrical Characteristics of Super Capacitor based Energy Storages

Super capacitor energy storages have very high power density and low energy density in comparison with battery energy storages. In this case, it is impartment to well configure the super capacitor energy storage as peak power unit in each particular application (e.g. hybrid electric vehicle). Therefore, the simple and accurate model of super capacitors is required. In this paper, the methods of identifying and modeling their electrical characteristics are presented. Based on the detected parameters, the modeling of super capacitors is evaluated both in simulation system and in the test setup of a dedicated passenger car in ECE15 cycle.
