The results show that all the synthesized manganese cobalt oxides are composed of cubic spinel MnCo₂O₄. The addition of surfactant leads to the change of the morphology of MnCo₂O₄ from nanoarray to urchin-like nanospheres and increases the specific surface area, which is beneficial to improve the electrochemical performance of the MnCo₂O₄ electrode. The electrochemical test reveals that the urchin-like MnCo₂O₄ nanospheres delivered a high specific capacity of 2019 F/g at a 1 A/g and 1144 F/g at 5 A/g, respectively. The specific capacity of MnCo₂O₄ electrode reaches 512 F/g at 10 A/g and retains 96 % of the initial capacity after 2000 cycles at 10 A/g, which maintains an extraordinary cycling performance.

The second life is an economic and environment-friendly alternative for battery management. The development of fast, low-cost, and reliable diagnostic methodologies makes it possible to increase the economic benefits and reduce the remanufacturing time of second-life batteries (SLBs). In the present work, battery state of health (SOH) distribution analysis, incremental capacity (IC), internal resistance (IR), and electrochemical impedance spectroscopy (EIS) were applied as diagnostic methodologies for two different chemistries of lithium-ion batteries previously used in electric vehicles (EV). In addition, module equalization in batteries was done in order to assess whether the state of module charge (SOC) variation affects the SOH. The results demonstrate that the diagnosis methodology depends on the chemistry of the battery, and that there is no single reliable diagnostic procedure that can be applied to all types of lithium-ion batteries. It was determined that the most adequate diagnostic method for LFP batteries (LiFePO₄ cathode) is the IC method, while for NMC batteries (LiNi_0.33Mn_0.33Co_0.33O₂ cathode) the IR and EIS diagnostic methods are the most appropriate. Similarly, the present work proposed a simple methodology for IC capacity diagnosis and a general expression for SOH determination by IC and incremental voltage diagnosis of LFP batteries. Higher stability of LFP respect to NMC modules was observed during the SLBs performance, retaining &gt;99 % after 500 cycles for LFP, compared with 90.2 % for NMC.

The proposed study aims to utilize the multi-functional capabilities of BUs to minimize the hourly costs of MG and thereby reduce the overall daily operating costs of MG. To achieve this, various potential scenarios are considered within the system policy to efficiently utilize the BUs for performing multiple functions including matching power generation from the renewable energy sources (RESs) with the demand (G/D) and performing energy arbitrage (EA). This work considers several factors, including two modes of MG operation (grid-connected mode and islanded mode), as well as demand-side management (DSM). Furthermore, the study addresses uncertainties associated with various parameters, affecting wind power and solar power, using the Latin Hypercube Sampling (LHS) approach. The metaheuristic technique known as Moth-Flame Optimization (MFO) is utilized to solve the formulated constrained nonlinear optimization problem. To verify the obtained optimal solutions, the Hybrid Firefly and Particle Swarm Optimization (HFPSO) technique is also utilized. Several case studies, considering various operating conditions, are done to investigate the proposed study. Finally, a comparison is made between four case studies to clarify the importance of the multi-functional BUs in achieving the objective of the proposed study.

As energy consumption continues to grow on a global scale, the shift towards renewable energy is crucial for maintaining sustainable development. Solar power, in particular, has emerged as a leading renewable resource due to its widespread availability and the potential to cover a significant portion of global energy demand. Nonetheless, the variability of solar energy poses challenges for ensuring a steady power supply. To overcome this, efficient energy storage systems, such as advanced batteries and thermal energy storage (TES) systems are essential. There is growing attention on solar energy storage, with a particular focus on phase change material (PCM) and TES systems. Here, a compact thermal energy storage (CTES) system with two heat transfer fluid plates and one rib-enhanced PCM plate was investigated to minimize the response time. RT42 was employed as the PCM within the plate. Selected for its suitable melting temperature range of 311.15–315.15 K, RT42 facilitates efficient thermal management, enabling effective storage and release of latent heat. Eight aluminum-made ribs were embedded to allow heat to penetrate deeper into the storage container. According to the several geometric parameters of the ribs such as angle of lower ribs, angle of upper ribs, and the distance between ribs, different configurations of ribbed CTES systems were introduced. Additionally, an artificial neural network-based anticipation model was introduced to predict system's melting performance, facilitating faster and more accurate optimization of design parameters. This innovative approach aids researchers in accelerating their future work on similar energy storage systems. Eventually, an optimal configuration (OC) was derived from the genetic algorithm and the anticipation model. Based on the results, the rib-less specimen took 19,648 s to melt completely, which was 118.2 % longer compared to the OC. This indicated a difference of nearly 3 h between the two systems, underscoring the effectiveness of the optimal configuration in conserving thermal energy throughout the day. Moreover, the rib-less system needed 130.5 % more time to melt 50 % of the PCM and 129.4 % more time to melt 80 % of the material. This stark difference further emphasized the efficiency of the OC in the entire stages of the charging in the CTES system.

This system requires energy management systems that efficiently split the power during real driving cycles. This paper outlines a design methodology for creating a Multilayer Perceptron neural controller that governs the power distribution between the storage system components. In parallel, a Proportional-Integral-Derivative controller was implemented to ensure voltage regulation in the primary DC bus, ensuring stable operation of the entire system and providing flexibility to the neural design. The controller was tuned using particle swarm optimization, hippopotamus optimization, and differential evolution algorithms, designed to minimize the battery root-mean-square current in a comprehensive vehicle simulation. The training was structured into layers to approach the physical problem and controller optimization facets. The controller’s primary goal is to minimize the battery strain, mitigating stress events and prolonging its lifespan. The energy management neural controller was designed using a simple drive cycle and later validated with a realistic cycle. The findings demonstrate the feasibility of achieving a significant reduction in current, both in peak value and on average, especially when compared to basic energy management strategies. The process uncovered a strategy that prioritizes the use of the supercapacitor in power balance, with this effect being more pronounced during critical load events. The main bus voltage remained stable, with no deviations exceeding 5%, owing to the voltage regulator’s stability. Additionally, the particle swarm optimization and the hippopotamus optimization techniques exhibited notable performance compared to the differential evolution algorithm for this problem.
