At the same time, hybridization of SCs with EV batteries, such as valve-regulated lead-acid (VRLA), nickel-metal hydride (Ni-MH), lithium-ion (Li-ion), and PbA batteries, has been proposed [31; 32; 33; 34]. Researchers have stated that SCs may appear as an alternative to replace existing storage batteries, as energy density is less important than power density for vehicle acceleration [35; 36; 34; 37]. It has also been stated that a successful energy storage system should provide more power by improving the vehicle's performance; the storage system should have a longer operating life, stable performance at low temperatures, and be lighter and smaller in size [37]. However, the ultimate use of this application will depend on the development of this system and consumer demand. Recent studies have shown that consumers are reluctant to choose EVs unless they can be used for transportation over longer distances without range anxiety [38]. Although SCs are not suitable for use as a stand-alone storage source in EVs, they are a very suitable storage source for the hybrid storage option. Due to the high cost of SCs, battery-SC hybrid systems have not been widely adopted or used compared with Li-ion batteries [39]. The most important reason for this is that the price of a SC with the same energy capacity as a Li-ion battery is 275% higher [40]. However, studies have shown that the price difference between the lifecycle of SCs and Li-ion batteriesis a false issue when the entire lifetime of the EV is considered [41; 42; 43]. Studies have shown that hybrid energy storage systems (HESS) with SCs increase the cost by about 25% but reduce the operating costs by 10% to 27% by extending the battery life [42]. In addition to all these advantages, an important advantage of SCs compared to Li-ion batteries is that they have a wide operating temperature range (\(-20\)\({}^{\circ}\)C to \(+80\)\({}^{\circ}\)C) [44; 45]. This provides an advantage in the use of battery-SC hybrid storage systems in EVs. Thus, using SCs outside the temperature limits of Li-ion batteries can help extend the lifetime of energy sources. A wider temperature range can facilitate fast charging. The management of HESS is important and needs to be compatible with the air and liquid thermal management systems. Another advantage of battery-SC HESSs for EVs is that they do not pose a risk of ignition and combustion in the event of a traffic accident [46]. The main objective of this study is to increase the battery life by reducing the negative effects of regenerative braking on the battery in EVs. Since the battery is one of the most costly components of EVs, a SC was first used to reduce the charge/discharge cycles. The limitations between these storage components were determined by a fuzzy logic controller. In the study, battery tests were performed using two different simulation programs to demonstrate the effect of this method on the battery. The ADVISOR and Siemens Simcenter Flomaster programs were used to perform the tests in the NEDC cycle. In this way, the effect of the HESS with a SC on battery aging was determined. A review of the existing literature shows that while the studies generally focus on how the regenerative braking system works and how the energy is collected, there are limited studies on how to store the energy obtained and how to use it later [46; 47]. This study focuses on the existing gap in the literature and highlights the innovative approach of the regenerative braking system to reduce the negative effects on the battery and improve battery life. The simulations clearly demonstrate the positive impact of the hybrid storage system with a SC on battery life. This study will be an important step towards the sustainability of EV technology. The remainder of this paper is organized in the following sections.
