Customer ServiceThe supercapacitors are being used to regulate the microgrid voltage and to improve the system stability. In recent studies, the supercapacitor provides the error component of the battery current in the proposed control scheme.
The development of supercapacitors started in the 50 s of the 20th century. First experiments started between 50 s and 70 s and were conducted by US companies General Electric (GE) and Standard Oil of Ohio (SOHIO). These first electrochemical supercapacitors reached the capacity around 1F. This type of supercapacitors was patented in 1971 by SOHIO.
In supercapacitor, the conductors have been replaced by the porous electrode, which provides efficient surface areas for the adsorption of ions. Also, the separation between two opposite charges is in the nanometer range, which further contributes to high capacitance than the conventional capacitor.
Basically, the supercapacitor is classified by two types of charge storage mechanisms, where pure electrostatic, non-Faradic processes are called electric double-layer capacitor (EDLC). The other includes the Faradaic process, where a reversible redox reaction is involved and known as pseudocapacitor.
As a result, supercapacitors may become an attractive power solution for an increasing number of applications. This brief overview focuses on the different types of supercapacitors, the relevant quantitative modeling areas, and the future of supercapacitor research and development.
A device or supercapacitor can be identified as a system consisting of a capacitor in a series arrangement with a resistor. The resistance offered by this resistor is known as ESR which can be found at the start of the discharging process in CCCD measurements .
