Temperature fluctuations pose a critical challenge for infrastructure, necessitating functional concrete to protect structures and promote sustainability. Self-heating concrete and phase change material (PCM) concrete are closely linked to thermal energy, with the former focused on heat generation and the latter on heat storage. This study aims to explore the self-heating performance of modified PCM concrete. Carbon-based materials, chosen for their low electrical resistance and high thermal conductivity, are incorporated to enhance the PCM concrete. Carbon black (CB), carbon nanotubes (CNT), and carbon fibres (CF) with various dimensions and scales, are combined to achieve optimal performance. Materials below a threshold yield minimal change, as they fail to establish the crucial conductive circuit. The self-heating behaviour becomes pronounced with increased in materials, reaching an optimal temperature rise up to 31.2 °C in one hour. However, the group with the highest content of materials experiences a reduced final temperature of 23.9 °C and an increased electrical conductivity of 40 Ω. CB and CNT show different efficiency improvements, and the ideal combination is proposed as 0.3 % CNT and 0.75 % CB. Inorganic hydrated salt-based PCM reduces electrical conductivity by 12 % – 35 % in its liquid state due to free ions, potentially enhancing self-heating capability, though its impact is less significant compared to carbon materials. Overall, the optimum group demonstrates significant self-heating behaviour, high efficiency, and low material cost. Models and electrical impedance results validate these observations and provide novel insight into the self-heating performance of PCM mortar with hybrid carbon-based materials.

温度波动对基础设施提出了严峻挑战，需要功能性混凝土来保护结构并促进可持续性。自加热混凝土和相变材料（PCM）混凝土与热能密切相关，前者侧重于发热，后者侧重于储热。本研究旨在探索改性 PCM 混凝土的自加热性能。碳基材料具有低电阻和高导热性，可用于增强 PCM 混凝土的性能。碳黑（CB）、碳纳米管（CNT）和碳纤维（CF）以不同的尺寸和尺度组合在一起，以达到最佳性能。低于临界值的材料产生的变化极小，因为它们无法建立关键的导电回路。随着材料含量的增加，自热行为变得明显，在一小时内达到最佳温升，最高可达 31.2 °C。然而，材料含量最高的一组的最终温度降低了 23.9 °C，导电率提高了 40 Ω。CB 和 CNT 显示出不同的效率改进，理想的组合是 0.3 % CNT 和 0.75 % CB。无机水合盐基 PCM 在液态下会因游离离子而使导电率降低 12% - 35%，从而有可能增强自加热能力，但与碳材料相比，其影响并不显著。总体而言，最优组显示出显著的自加热性能、高效率和低材料成本。模型和电阻抗结果验证了这些观察结果，并为使用混合碳基材料的 PCM 砂浆的自加热性能提供了新的见解。

An efficient battery thermal management system is essential for ensuring the safety and stability of lithium-ion batteries in electric vehicles (EVs). As a novel battery thermal management system (BTMS), refrigerant evaporation cooling has been widely studied due to superior heat transfer efficiency and more compact circuit design. A comprehensive understanding of the operating conditions and structural parameters is essential for system performance. In this study, a refrigerant evaporative cooling system option was proposed and analyzed. A thermal model of lithium-ion batteries was developed and validated experimentally. The impact of different operating conditions on the thermal and power consumption performance was analyzed. Based on traditional cold plates, several novel designs were proposed and compared to improve performance. The system's effectiveness at high discharge rates is validated by flow rate matching. The results showed that the inlet velocity had a more significant impact on the thermal and power consumption performance than the inlet gas-phase volume fraction and saturated evaporation temperature. Besides, the proposed design can reduce the maximum temperature from 34.24 to 28.91 °C and the temperature difference from 5.7 to 2.4 °C at 1C discharge rate. Moreover, the thermal performance can be ensured under 3C discharge rate. This study is helpful for the development of BTMS based on refrigerant evaporative cooling in EVs.

The increasing use of renewable energy sources are solving environmental issues, energy shortage problems and result in economic growth. Microgrid can provide a framework for connecting RESs to the utility grid, but high penetration of RESs make it difficult to lower the Rate of Change of Frequency (RoCoF). In this research, a self-adaptive Virtual Inertia Control (VIC) technique is proposed to tackle this instability issue. VIC method simulates virtual inertia, enhancing inertia of the overall system and frequency stability. VIC technique links energy storage systems to the utility and helps with power supply. However, an accurate analysis is necessary to regulate the Virtual Inertia (VI) constant value, which could adequately eradicate the adjustment mistakes & system instability. Fuzzy logic controllers can tackle non-linear problems and provide robustness, and reliability. This research presents a fuzzy based self-adaptive VIC system for stable load frequency regulation in low-inertia microgrid. In addition to this, a fuzzy based secondary frequency control is also proposed in this study. A fuzzy based self-adaptive VIC is developed for VI constant emulation using real power fluctuations of RESs and frequency regulations. The Arithmetic optimization algorithm technique is used to obtain the optimized controller parameters. Efficacy of the proposed self-adaptive VIC with fuzzy based secondary thermal controller is validated against no VIC with integral and fuzzy based secondary frequency controller, standard VIC with integral as well as fuzzy based secondary frequency controller and self-adaptive VIC with integral secondary controller for high/low renewable sources penetrations and system parameter variations. Finally, real time validation of the proposed VIC approach has conducted with the help of OPAL-RT 5700 and the experimental results are compared with conventional VIC method.

可再生能源的使用日益增多，不仅解决了环境问题和能源短缺问题，还带来了经济增长。微电网可以为可再生能源与公用电网的连接提供一个框架，但可再生能源的高渗透率使得降低频率变化率（RoCoF）变得十分困难。本研究提出了一种自适应虚拟惯性控制（VIC）技术来解决这一不稳定问题。VIC 方法可模拟虚拟惯性，增强整个系统的惯性和频率稳定性。VIC 技术将储能系统与电力公司连接起来，有助于电力供应。然而，要调节虚拟惯性（VI）恒定值，必须进行精确的分析，以充分消除调节错误和系统不稳定性。模糊逻辑控制器可以解决非线性问题，并提供鲁棒性和可靠性。本研究提出了一种基于模糊自适应的 VIC 系统，用于低惯量微电网中稳定的负载频率调节。此外，本研究还提出了基于模糊的二次频率控制。利用可再生能源的实际功率波动和频率调节，开发了一种基于模糊自适应的 VIC，用于 VI 恒定模拟。算术优化算法技术用于获得优化的控制器参数。在可再生能源渗透率高/低和系统参数变化的情况下，与不带积分和模糊二次频率控制器的自适应 VIC、带积分和模糊二次频率控制器的标准 VIC 以及带积分二次控制器的自适应 VIC 相比，验证了所提出的带模糊二次热控制器的自适应 VIC 的功效。最后，在 OPAL-RT 5700 的帮助下，对所提出的 VIC 方法进行了实时验证，并将实验结果与传统 VIC 方法进行了比较。

Despite their effectiveness in improving indoor thermal conditions and reducing energy consumption, the performance of phase change materials (PCMs) in buildings is highly dependent on ambient conditions. In desert climates, where summer outdoor temperatures can exceed 40 °C and nighttime temperatures rarely drop below 30 °C, PCM application can be challenging and may lead to undesirable outcomes if not implemented properly. Therefore, an optimization study was conducted to assess the feasibility of using PCMs to enhance thermal performance and reduce the energy consumption of residential buildings in desert climates. The optimization was performed for different seasons and involved PCM's position and transition temperatures, cooling and heating setpoints, and combining mechanical ventilation for cooling. The results indicated that optimization based on summer conditions resulted in the most significant reduction in annual energy consumption (AEC), given the greater demand for cooling energy. The optimum performance was achieved with a cooling setpoint of 25–26 °C, PCM transition temperatures of 30–31 °C for externally applied PCM, 28 °C for internally applied PCM on external walls, and 24–26 °C for internal partitions. Under the investigated conditions, using the optimal PCMs for the cooling setpoints 25 °C and 26 °C achieved maximum AEC reduction of 24.1 % and 30.4 %, respectively, while the annual thermal discomfort (ATD) was 3 % and 30.5 %, respectively. Despite the higher ATD with the optimal PCM based on the cooling setpoint of 26 °C, 96 % of the operative temperature was maintained below 27 °C, indicating an acceptable thermal condition. The findings confirm that optimal PCMs can perform well in desert climates in reducing energy consumption and improving indoor thermal conditions.

尽管相变材料（PCM）在改善室内热条件和降低能耗方面非常有效，但其在建筑物中的性能却在很大程度上取决于环境条件。在沙漠气候条件下，夏季室外温度可超过 40 °C，夜间温度很少低于 30 °C，因此应用相变材料具有挑战性，如果实施不当，可能会导致不良后果。因此，我们开展了一项优化研究，以评估在沙漠气候条件下使用 PCM 提高热性能和降低住宅建筑能耗的可行性。优化针对不同季节进行，涉及 PCM 的位置和过渡温度、冷却和加热设定点，以及结合机械通风进行冷却。结果表明，由于对制冷能源的需求量较大，基于夏季条件的优化能够最显著地降低年能耗（AEC）。在制冷设定点为 25-26 °C、外部应用 PCM 的 PCM 过渡温度为 30-31 °C、外墙内部应用 PCM 的 PCM 过渡温度为 28 °C、内部隔墙的 PCM 过渡温度为 24-26 °C的条件下，实现了最佳性能。在调查条件下，使用最佳 PCM 制冷设定点 25 °C 和 26 °C，最大 AEC 降低率分别为 24.1 % 和 30.4 %，而年热不适度（ATD）分别为 3 % 和 30.5 %。尽管基于 26 °C 制冷设定点的最佳 PCM 的 ATD 较高，但仍有 96% 的工作温度保持在 27 °C 以下，表明热条件可以接受。研究结果证实，在沙漠气候条件下，最佳 PCM 在降低能耗和改善室内热条件方面表现出色。

With global warming on the rise, the push for zero-emission transportation continues to grow. The transportation sector’s solution to increasing climate concerns has been to promote electric vehicles (EVs) as a replacement for traditional internal combustion engine (ICE) vehicles. Although the objective of EVs seems obvious, EVs come with an undeniable problem: battery decommission and disposal. EV batteries are required to deliver power so that the vehicle can accelerate quickly and drive extended distances; the battery has to be at a sufficient state of health (SOH) to deliver satisfactory results. Once a battery reduces to a SOH that is no longer adequate, it must be retired from the EV. The significant increase in the number of EVs and their forecasted exponential growth also comes with an accumulation of retired batteries, the handling of which raises serious concerns.

随着全球变暖的加剧，人们对零排放交通工具的需求不断增加。为了解决日益严重的气候问题，交通部门一直在推广电动汽车（EV），以取代传统的内燃机汽车（ICE）。尽管电动汽车的目标似乎显而易见，但电动汽车也伴随着一个不可否认的问题：电池的退役和处理。电动汽车电池需要提供动力，使车辆能够快速加速和长距离行驶；电池必须处于足够的健康状态（SOH），才能提供令人满意的结果。一旦电池的 SOH 值降低到无法满足要求的程度，就必须从电动汽车中报废。电动汽车数量的大幅增加及其指数级增长的预测也伴随着退役电池的积累，其处理问题引起了人们的严重关切。不过，研究表明，退役电动车电池的再利用前景广阔，可以作为二次电池（SLB）为电动车带来新的生命。目前正在开展研究，以解决在各种条件下的各种应用中与新电池相比在性能和成本方面存在的问题。此外，还在进行环境评估，以证明这项创新技术的合理性。本综述文件概述了与这些主题相关的现有文献和最新研究成果，并提供了 SLB 与新电池的简要比较。

The transportation sector’s solution to increasing climate concerns has been to promote electric vehicles (EVs) as a replacement for traditional internal combustion engine (ICE) vehicles. Although the objective of EVs seems obvious, EVs come with an undeniable problem: battery decommission and disposal. EV batteries are required to deliver power so that the vehicle can accelerate quickly and drive extended distances; the battery has to be at a sufficient state of health (SOH) to deliver satisfactory results. Once a battery reduces to a SOH that is no longer adequate, it must be retired from the EV. The significant increase in the number of EVs and their forecasted exponential growth also comes with an accumulation of retired batteries, the handling of which raises serious concerns.
