This paper proposes a hybrid PV-battery/supercapacitor multilayer control strategy to address various issues. The key features are: A power exchange algorithm ensures tight balancing of the battery''s state of charge (SoC). Automatic control maintains the supercapacitor''s SoC at an average value.
Four case studies assess the practical performance of RFOPID control compared with that of other typical linear/nonlinear control strategies. At last, a dSpace based hardware-in-the-loop (HIL) test is performed to verify its effectiveness for practical applications.

Implementation of an estimator-based adaptive sliding mode control strategy for a boost converter based battery/supercapacitor hybrid energy storage system in electric vehicles
With the growing global energy demand and the pressing need for a clean energy transition, supercapacitors (SCs) have demonstrated significant application potential in electric vehicles, wearable electronics, and renewable energy storage systems owing to their rapid charge–discharge capability, exceptional power density, and prolonged cycle life. The
This article investigates the problem of robust tracking control for a fully active hybrid energy storage system (HESS) in electric vehicles (EVs) consisting of battery and supercapacitor (SC) modules.
However, effective control remains a critical aspect. Conventional control methods are reviewed, highlighting their limitations. To overcome these challenges, a novel approach integrating fuzzy logic and rule-based systems is proposed.
In this chapter, the control and energy management of a solar-powered electric vehicle energy storage system is investigated. The proposed system is composed of a photovoltaic system as a renewable energy source, batteries, and supercapacitors as
Some common synonyms of robust are hale, healthy, sound, well, and wholesome. While all these words mean "enjoying or indicative of good health," robust implies the opposite of all that is delicate or sickly.
Abstract This study proposes a robust fractional-order PID (RFOPID) control approach for supercapacitor energy storage (SCES) system applied on distribution network.
In all control methods and strategies for the battery and supercapacitor combined energy storage system, the primary objectives are to divide the power into two components—low frequency and high frequency and regulate the DC link voltage.
Also, a combined supercapacitor and battery energy storage system are considered to control the DC bus voltage, which is connected through a two-way DC-DC converter. In this paper, to increase the controllability, the active structure is used for hybrid storage.
This figure shows that, as expected by using the proposed energy management system, soft power has been drawn from the battery, and the supercapacitor has responded to power changes. The AC network also receives a part of the power that is not compensated by the battery. Fig. 12. Power profile in the case of network power shortage.
Combining batteries and supercapacitors, these systems offer a promising solution for addressing various network challenges, such as power quality enhancement and voltage stabilization. However, effective control remains a critical aspect. Conventional control methods are reviewed, highlighting their limitations.
An enormous variety of energy management strategies (EMS) have been proposed to effectively protect the battery by using a supercapacitor in electric vehicles. These strategies can be categorized into online EMS and offline EMS.
Additionally, the system effectively manages the charging of the battery and supercapacitor within permissible limits, ensuring their longevity. Conversely, in power surplus situations, the controller absorbs excess power to stabilize the bus voltage, maintaining efficient operation even under varying charge levels.
