Electric cars because of the advantages of energy saving and environmental protection have been in our lives quite universal, but its energy storage devices of storage capacity and service life is a major issue of concern. To address this issue, has been put into use a lot of energy storage devices. In this paper, this new super-capacitor energy devices. Supercapacitor both power density of conventional capacitors, and rechargeable battery of the advantages of high energy density, fast charge-discharge, long life, is energy efficient and practical components, has been widely used.

This paper analyzes the supercapacitor energy storage device of the constant principle of bi-directional power flow, and in accordance with the characteristics of super-capacitors, supercapacitors gives the design method of energy storage devices. Supercapacitor-based equivalent circuit model, the energy storage supercapacitor basic characteristics, the establishment of DC / DC converter m
