Development of a Smart Supercapacitor Energy Storage System for Aircraft Electric Power Systems

Abstract

This paper presents the development of a supercapacitor energy storage system (ESS) aimed to minimize weight, which is very important for aerospace applications, whilst integrating smart functionalities like voltage monitoring, equalization, and overvoltage protection for the cells. The methodology for selecting the supercapacitor cells type/size is detailed to achieve the safest and most energy-dense ESS. Additionally, the development of the interface electronics for cells’ voltage monitoring and overvoltage protection is presented. The proposed design implements a modular distributed architecture coordinated using communication buses to minimize the wirings and associated complexity and to enable system reconfiguration and expansions, as well as fault diagnoses. Validating the proposed ESS functionalities has been done via experimental testing and the results are presented and discussed.

Combined Supercapacitor and Battery Sliding Mode Control for Aeronautic Application

“…As in system (8), the last equation in ( 9) represents the internal dynamics for system (9). Then, for control variables u 1 and u 2 , let α * i ∈ (0, 1] ∩ (0, 3G im /G iM ), i ∈ {1, 2} and…”

“…Furthermore, the installation onboard of supercapacitors has been proved to be instrumental to reduce the stress on the mechanical parts of the aeronautic generator. In fact, as showed in [9], [10], supercapacitors can be employed to provide fast current transient required by Electro-Mechanical Actuators (EMAs) during their operations, thus allowing the main generator to provide only the slow transient component to the EMAs. Finally, another possible strategy that has been investigated to avoid the overload of the aircraft generator relies on loads power partial shedding (see [11] and references therein).…”

Ultra-High Cycling Stability of 3D Flower-like Ce(COOH)3 for Supercapacitor Electrode via a Facile and Scalable Strategy

“…Among various energy storage technologies, supercapacitors have attracted significant attention from academia and industry over the past few decades due to their distinguished properties, including much higher energy density than traditional capacitors and superior power density than batteries [4]. In addition, supercapacitors have also shown great potential in many other applications, such as aerospace, electric vehicles, microsensors, and portable electronics [5][6][7].…”

Electrical and Mathematical Modeling of Supercapacitors: Comparison

“…Research on the development of high-performance technologies and power devices has been extensively pursued by many researchers in recent years due to the global energy crisis and deteriorating pollution [1,2]. Electrochemical energy storage devices are unavoidable parts of a clean energy portfolio [3,4]. Among these devices, supercapacitors (SCs) are electrochemical devices, electrochemical double layer capacitors or ultracapacitors are also common names for energy storage devices, whose storage mechanisms are based on a faradic process [5][6][7][8].…”
