Abstract

Super capacitor energy storages have very high power density and low energy density in comparison with battery energy storages. So it is important to well configure the super capacitor energy storage as peak power unit. In this case, the simple and accurate model of super capacitors is required. Therefore, the methods of modeling and identifying the electrical characteristics of super capacitors are proposed in this paper. 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. Finally the methods of identifying and balancing voltage difference of super capacitor energy storage are also presented, which can ensure high available energy capacity and long life time of super capacitors.
