The proposed BMS facilitates constant current and constant voltage charging to maintain optimal battery performance during normal operation. This BMS is designed for effective control, monitoring and protection of two lead-acid battery units to form battery energy storage system (BESS). Furthermore, it is capable of isolating batteries in abnormal conditions and operates them independently to provide reliable supply at output terminals with full capacity. The system utilizes a 30 V DC source derived from AC mains or solar photovoltaic system. This supply is used to charge the BESS and also supply to the load. In the event of failure of 30 V supply, it seamlessly transits to BESS mode to supply power to boost converter to maintain constant 48 V DC output at load terminal. The proposed system architecture not only enhances power reliability but also improves overall system efficiency, making it well-suited for critical applications require continuous and stable power supply. Simulation studies using Matlab/Simulink and analytical results using TINA (Tool kit for Interactive Network Analysis) are presented to show that 48 V DC supply is maintained at output terminals during failure of input 30 V DC source or failure of one battery unit.","PeriodicalId":11765,"journal":{"name":"Energy Storage","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141488782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On a shell-tube type heat storage system, computational and experimental research was done to determine how to charge a heat storage system using honeybee wax-biodegradable phase change material. This paper examines the impact of single, double, and triple inner heat transfer fluid tubes on the melting properties of bee wax in relation to vertical and horizontal eccentricity. Through the experimental examination of a lab-scale prototype, the computational model was verified. A computational model was used to investigate the impact of eccentricity on different configurations for the melting process. Utilizing multiple tubes significantly shortened the charging time, according to the system analysis. In a vertically downward direction, melting time reduced as eccentricity increased. Compared to the single tube concentric case, the maximum melting time reduction for the single-, double-, and triple-tube cases was 63.7%, 67.0%, and 68.34%, respectively.","PeriodicalId":11765,"journal":{"name":"Energy Storage","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141435623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Carbon electrode material derived from biomass is used for energy storage (ES) because it has distinct qualities in porosity, a large specific surface area, and excellent conductivity. Furthermore, these materials' homogeneous, flawless biological structures can be used as models to create electrode materials with accurate geometries. The ES devices, known as SCs, also known as ultra-capacitors, serve as a link between a capacitor and a battery. Due to their charge storage, SCs can produce a much higher density than batteries. Several factors, including the electrode's potential window, the electrode materials characteristics, and the electrolyte choice, have a major effect on SC performance. Therefore, all efforts have been made to develop SC electrode materials. This paper explains the different types of SCs and how they work. The various available biomass resources, as well as the methods for producing them, are outlined. In addition, the different types of electrode materials, activation methods, heteroatom functionalization, and electrolyte types are all thoroughly examined. The application and research advancement of biomass-derived carbon used in SCs over the past 3 years are highlighted. Furthermore, this research outlines the benefits of SCs for the environment and the economy, as well as present challenges and future recommendations for advancing biomass-derived carbon applications. This article aims to give an in-depth knowledge of carbon-based biomass materials that are used in SCs.","PeriodicalId":11765,"journal":{"name":"Energy Storage","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141435639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At a temperature of 23°C with natural convection, the thermal performance of a cylindrical (LFP) battery is experimentally studied. In this study, the battery is fully charged. After reaching 14.6 V, the battery is charged at a current of 4.8 A for 10 min to allow for stabilization. The battery is then depleted at 4.8 A until its voltage hits 10.5 V, followed by an additional 10-min resting time. The processes reached their highest and lowest temperatures, respectively, were 29°C and 22°C. The battery is charged for a total of 46.877 Ampere-hours (Ah) during the course of the 10-h operation at a constant current of 4.8 A. Similar to this, a 10-h discharge operation is carried out with a constant current of 4.8 A, yielding a discharge of 47.207 Ah. The processes reached their highest and lowest temperatures, respectively, were 36°C and 24°C. Another possibility is to charge the battery at a steady 24 A until the voltage reaches 14.6 V, then let it rest for 10 min, a further 10-min rest period is added after it is discharged at 24 A until its voltage hits 10.5 V. After 5 h of charging at 24 A, the capacity is 46.958 Ah, and after 5 h and 47.51 min of discharging at 24 A, the capacity is 47 Ah.

Results were taken for the two systems: The photovoltaic solar chimney which contains phase change material (SCPV-PCM), and the photovoltaic solar chimney which does not contain phase change material (SCPV). The finding demonstrated that the PCM affects the SCPV electrical and thermal performance; the results were as follows: The electrical power for the SCPV-PCM system increased during the day and its highest value at noon was 384.34 W, and then it began to decrease. The SCPV system had a higher power at the end of the test, 73.24 W, due to the lower temperature of the PV panel. The highest electrical efficiency was for the SCPV-PCM system at the beginning of the test, reaching the highest value of 13.12%, then it decreased at the end of the test to be less than the SCPV system at 5:00 pm. The thermal efficiency of the SCPV-PCM arrangement is lesser than the arrangement that does not contain PCM, reaching its highest value at noon, which was 57.1% for the SCPV system.

They are an efficient alternative to existing energy sources due to their synergistic contribution from individual element. We demonstrate the development of nanostructured HEA (FeCoNiCuMn) as a cathode material with specific capacitance (Cs) of ~388 F g−1 (5 mV s−1). As anode material, green graphene (rice straw biochar) synthesized using pyrolysis shows a maximum Cs of ~560 F g−1 at similar scan rate (5 mV s−1). A hybrid asymmetric liquid state device was assembled using the FeCoNiCuMn nanostructured HEA and green graphene as electrodes. Utilizing the green source, the device provided a high Cs of 83.22 F g−1 at 2 A g−1. The specific energy of the device was 33.4 Wh kg−1 and specific power of 1.7 kW kg−1. The electrochemical behavior of each element in the high entropy composition was studied through post X-ray photoelectron spectroscopy and scanning electron microscopic analysis. The chemical behavior of FeCoNiCuMn is further investigated using DFT studies. The enhanced electrochemical properties and synergistic contribution of each element of the HEA is studied via d-band theory.
