Super capacitor bank operating characteristics have an important impact on the energy conversion efficiency and the construction cost of the hybrid energy storage system. To research the parameters and control properties of super capacitor in energy storage system, to establish a practical mathematical model and to propose the optimal design is important to improve the overall performance of the hybrid energy storage system. This paper presents the mathematical modeling of battery super capacitor hybrid energy storage system, studies the target parameters setting of hybrid energy storage system and the capacity configurations of super capacitor, and proposes an optimized design of the super capacitor bank. Finally, based on EMR verifies the theory.
