“…The hybrid optimization based approach was introduced in other works. [13][14][15] In this article, the behavior of an SC is modeled using a basic electrical circuit with an equivalent resistance in parallel (Rp), an equivalent resistance in series (Rs), and a capacitor (C). These three parameters are estimated for five different mathematical approaches by applying interior point optimization and using a set of experimental data.…”

Summary In this paper, we study a supercapacitor model represented by an equivalent RC circuit considering five different types of derivatives: Caputo, Caputo‐Fabrizio, and Atangana‐Baleanu fractional derivatives and the conformable and integer‐order derivatives. A set of experimental data from six commercial supercapacitors are used to estimate the parameter values for each derivative model by applying interior point optimization. The results show that the most accurate approach is achieved with the conformable derivative followed by the Caputo fractional derivative.

The dependence on renewable energy to solve the major energy issues related to global warming and shortage of energy resources is increasing drastically. This has led to high level awareness of proper energy storage and management. In this regard, supercapacitors have evolved as an efficient energy storage solution and hence successfully employed in several applications. This is attributed to its high-power density, superior performance, and extended maintenance-free lifetime. Also, it is known for low equivalent series resistance, that means, only a small amount of energy is lost while its charging/ discharging even at high current. As a result, it has developed a lot of inquisitiveness among the research community of recent past for further exploration of different aspects of supercapacitors, ranging from material science, modeling and characterizations, engineering applications, and so forth. This review article aims at putting forth an exclusive study of their characterization of supercapacitor for different charging methods and applications. Further, the prime focus is given to the efficiency estimation of supercapacitors which is very essential as it denotes the amount of energy loss or the utilizable state of charge. The analysis has been carried out based on different charging methods and applications, which is essential for improving overall system reliability and performance. The purpose is to organize all important research carried out in this domain till date and to stimulate further insights for effective energy storage and management.

“…The fractional-order model is the implementation of fractional calculus that is applied to the circuit theory of the supercapacitor [45]. A fractional-order model is used to estimate the parameters of supercapacitors using data obtained from experiment and operating conditions [46]. The parameter required to be identified using fractional-order is fewer compared to the traditional RC ladder model and has a better efficiency in capturing the dynamic behavior of the supercapacitor [47], [48].…”

Supercapacitor is a relatively new type of electric component used to store energy compared to a battery. Supercapacitor charge and discharge cycle are faster compared to the battery along with higher power density which increase its application in recent years. However, supercapacitors have quite high self-discharge compared to batteries. This makes energy stored in supercapacitor decrease faster over time when not in use. Various study has been done towards the self-discharge behavior of SC which is both experimentally and in simulation. The simulation is done by various methods and models which have been proposed by previous researchers. Most of the methods that have been used were based on the Equivalent Circuit Model as it is the easiest method available. However, there is still another method proposed such as the Fractional-order model. This paper will review some of the methods and models used to study self-discharge behavior.
