Review of system topologies for hybrid electrical energy storage systems

The global need to solve pollution problems has conducted automotive engineers to promote the development and the use of electric vehicle technologies. This paper focuses on the fuel cell hybrid electric vehicle which uses a proton exchange membrane fuel cell as a main source associated to hybrid storage device: lithium ion battery and ultracapacitors. A common interest in such technology is to spread out the energy flow between its different sources in order to satisfy the power demand for any requested mission. However, the challenging task stills the optimization of this split to reduce hydrogen consumption and respect, at the same time, the system limitations such as admissible limits of storage system capacities and battery current variation. An adaptive filtering-based energy management strategy is proposed in this paper to ensure an optimum distribution of the energy between the sources taking into account dynamic and energetic constraints of each device. For more performance, a fuzzy logic system is used to adapt the frequency of separation with the system state evolution. A sliding mode control is applied to control electric characteristics (voltage and currents) in the considered hybrid power supply. Simulation results, obtained under MATLAB R /SimPowerSystems R for four driving cycles are presented. The proposed strategy achieved good performances by respecting the ultracapacitors state of charge while preserving the battery lifetime under various driving missions.

“…Moreover, with this hybridization of these complementary characteristics the requirements of the system can be decoupled with each hybrid energy storage system (HESS) device performing to its characteristic potential and hence achieve reduced ESS sizing, investment cost and optimize the efficiency of the overall ESS [10,11]. Several remarkable and brilliant reviews and studies have been presented over the last decade or so [20][21][22][23][24][25][26][27], which have meticulously outlined the: (1) descriptive topologies of HESS; (2) critical analytical comparison of HESS topologies; (3) topologies for active wind power suppression; (4) comprehensive critical reviews of HESS control strategies for power quality improvement in microgrids and (5) descriptive reviews on HESS control strategies in EVs. Consequently, there is a need to elucidate and organize these multi-dimensional applications, to highlight the versatile potential as well as the progress achieved by BESS-SCSS HESS in various multi-disciplinary fields.…”

This paper presents a comprehensive categorical review of the recent advances and past research development of the hybrid storage paradigm over the last two decades. The main intent of the study is to provide an application-focused survey where every category and sub-category herein is thoroughly and independently investigated. Implementation of energy storage systems is one of the most interestingly effective options for further progression in the field of alternative energy technology. Apart from a meticulous garnering of the energy resources regulated by the energy storage, the main concern is to optimize the characteristic integrity of the storage devices to achieve a practically techno-economic size and operation. In this paper, hybrid energy storage consisting of batteries and supercapacitors is studied. The fact that the characteristic of batteries is mostly complementary to that of supercapacitors, hybridizing these storage systems enhances their scope of application in various fields. Therefore, the objective of this paper is to present an inclusive review of these applications. Specifically, the application domain includes: (1) regulation of renewable energy sources, (2) contributions to grid regulation (voltage and frequency compensation, contribution to power system inertia), (3) energy storage enhancements (life cycle improvement, and size reduction), (4) regenerative braking in electric vehicles, (5) improvement in wireless power transfer technology. Further, this review also descriptively highlights the control strategies implemented in these domains of applications. The application-oriented review explicates the principle advantages with the hybridization of battery and supercapacitor energy storage systems that can be used as an insight for further development in the field of energy storage technology and its applications.

“…In contrast, the degree of controllability is increased using a fully active HESS, but there are some disadvantages, such as increased system losses, weight, and cost. In addition, efficiency also decreases because of the additional converter [20]. Similarly, a modular multilevel fully active HESS also adds complexity and cost.…”

“…SCs are normally used for high power storage, and LIBs are used as a high-energy-storage unit. The SC is utilized for the high power demand of the powertrain, while the LIB is used in low-power situations [20]. An energy management system (EMS) is required to fully utilize the energy of both storage units effectively [21].…”

Semiactive Hybrid Energy Management System: A Solution for Electric Wheelchairs

Many disabled people use electric wheelchairs (EWs) in their daily lives. EWs take a considerable amount of time to charge and are less efficient in high-power-demand situations. This paper addresses these two problems using a semiactive hybrid energy storage system (SA-HESS) with a smart energy management system (SEMS). The SA-HESS contained a lithium-ion battery (LIB) and supercapacitor (SC) connected to a DC bus via a bidirectional DC–DC converter. The first task of the proposed SEMS was to charge the SA-HESS rapidly using a fuzzy-logic-controlled charging system. The second task was to reduce the stress of the LIB. The proposed SEMS divided the discharging operation into starting-, normal-, medium-, and high-power currents. The LIB was used in normal conditions, while the SC was mostly utilized during medium-power conditions, such as starting and uphill climbing of the EW. The conjunction of LIB and SC was employed to meet the high-power demand for smooth and reliable operation. A prototype was designed to validate the proposed methodology, and a comparison of the passive hybrid energy management system (P-HESS) and SA-HESS was performed under different driving tracks and loading conditions. The experimental results showed that the proposed system required less charging time and effectively utilized the power of the SC compared with P-HESS.
