P CM 2 was demonstrated to be capable of decreasing the average temperature by (10,12,20) % and this was the only one capable of keeping the temperature gradient within the battery lower than 3 • C. The EG is used to increase the thermal conductivity of the PCM and therefore maximising the heat transfer rates. In terms of ageing effect (decrease of capacity with cycles), it can be seen from Figure 35 that the capacity decreases with cycles and this detrimental effect is more important for higher operating temperatures. In fact, with temperatures equal to (25,75) • C the capacity retention after 100 cycles is (94,77)%. ...

On the other hand, lowering the operating temperature of the batteries would result in decreasing the battery autonomy and capacity [1][2][3]. Common coolants used in TMSs of the batteries include air [4][5], liquid [6][7], and PCM among which the PCM cooling provides a more uniform battery temperature and low temperatures during the battery discharge [8].

The present paper deals with 3D numerical analysis of a battery thermal management system (TMS) including the Phase Change Material (PCM). The TSM comprises three annular fins located around the battery considering the tip clearance (TC) space between the fin tips and the alumina enclosure. The calculations were performed for four cases with different TCs (1.5 mm, 1 mm, 0.5 mm, and 0 mm). The entropy generation analysis was performed to determine the locations of the geometry with highest frictional and thermal irreversibilities. The results showed that the application of TC leads to improve the PCM free convection and thereby enhance the heat transfer rate. So that there is an optimum TC (0.5 mm) in which the highest heat transfer rate and lowest PCM melting time is obtained. Moreover, the magnitude of frictional entropy generation rate is much lower than that of the thermal term. For accurate estimation of the liquid fraction, fractional and thermal entropy generation rates, a new ensemble machine learning (ML), namely Gradient Boosting Decision Tree (GBDT), was developed based on the fin tip and flow time parameters as input features. The outcomes of ML-based simulation exhibited promising performance for the precision prediction of three understudy targets.

Poor heat dissipation and thermal runaway are most common in batteries subjected to fast charge or discharge and forced to work in hot or subzero ambient temperatures. For the safe operation of lithium-ion batteries throughout their lifecycle, a reliable battery thermal management system (BTMS) is required. A novel hybrid BTMS with a nickel-titanium (NiTi) shape memory alloy (SMA) actuated smart wire and phase change material (PCM) with expanded graphite (EG) is proposed in this study. A lumped electrochemical-thermal battery model is developed to analyze the efficiency of the proposed hybrid BTMS. The multiphysics BTMS is investigated by discharging at various electrical currents in both off-modes (inactivated SMA) and on-modes (activated SMA). Under on-mode BTMS operation, temperature elevation is reduced by 4.63 °C and 6.102 °C during 3 C and 5 C discharge, respectively. The proposed hybrid BTMS can be considered a competitive alternative for use in electrical vehicles due to its smart, compact, safe, and efficient performance in both cold and hot environments.

Preventing overheating and providing an ideal working temperature for safe operation are also important. Therefore, developing a BTM system that is both safe and reliable has a vital research goal. A comprehensive review of BTM with enhanced safety is presented in this article. The present study introduces the advances in the applications of BTM with cyclic stability served, high energy density, and electrification of automobiles.

Since Lithium-Ion Batteries (LIBs) have been major power sources for Electric Vehicles (EVs) and Energy Storage Devices (ESDs), Battery Thermal Management (BTM) has attracted the attention of numerous investigators. On the other hand, the application of Phase Change Materials (PCMs) in heatsinks (HSs) is an effective technique that has been approved for the electronic device cooling in transient operation in which the PCM melts as it absorbs the heat generated. Loading PCM has two positive effects of stretching the transient operation time (OT) as well as overheating postponement. They spend more time reaching the steady operation and simultaneously their base temperature in the steady-state is less. To improve the PCM-HS effectiveness and consider the low thermal conductivity of PCMs, installing fins, adding low melting alloy, loading nanoparticles, and metal foam was proposed by various researchers. Moreover, it is affirmed that using microencapsulation instead of PCM enlarged the OT by 74.6%. This review describes PCM-based HSs and illustrates their role in battery thermal management systems (BTMS) under different circumstances. The recent progress in this field is summarized and the future expectations are introduced.

This paper presents a novel combination of Phase Change Material (PCM) and fins as Thermal Conductivity Enhancer (TCE) for effective thermal management of battery module. A numerical study of the battery module thermal management system using PCM and internal fins for maintaining the battery temperature below the safe limit of 60 °C for more than one cycle is carried out. Both joule and entropic heat generation is considered for more generality in line with the actual case. An implicit finite volume based numerical methodology is used to solve the governing energy transport equation. Phase change in PCM is modelled using the implicit source based enthalpy method. A two-dimensional model is developed to study the thermal performance of battery module with 4S4P cell structure (16 cells) with PCM filled in between the cells. To improve the heat dissipation more effectively from PCM, metal fins as TCE are inserted in the space filled with PCM. Five fin structures with fin arrangement parallel to the boundary and tilted at an angle of 45° to the boundary are developed and studied to find the best configuration for effective transport of heat from the system to the boundaries and subsequent convection away to the ambient. Results shows more uniformity in temperature distribution within the battery module for better thermal performance for longer period of operation. Using fins embedded in PCM, the battery module temperature is maintained below 60 °C even after two and half discharge-charge cycle of 2C and 3C discharge rates where FS-3 structure is proved to be most efficient.

Jute is a cheap, eco-friendly, widely available material well-known for its cooling properties. In electric vehicles (EVs), dissipating a huge amount of the heat generated from lithium-ion batteries with an efficient, light, and low-power consumption battery thermal management system (BTMS) is required. In our previous study, jute fibers were proposed and investigated as a novel medium to enhance the cooling efficiency of air-based battery thermal management systems. In this paper, as the first attempt, jute was integrated with a phase change material (PCM) passive cooling system, and the thermal performance of a 50 Ah prismatic battery was studied. Temperature evolution, uniformity, and cooling efficiency were investigated. A comparison between the thermal behavior of the air-based BTMS and PCM-assisted cooling system was performed. The results indicated that adding jute to the BTMS increased the cooling efficiency and especially decreased the temperature development. Furthermore, the temperature difference (ΔT) efficiency was enhanced by 60% when integrating jute with PCM, and temperature uniformity improved by 3% when integrating jute with air-based BTMS. This article compared the integration of jute with active cooling and passive cooling; thus, it shed light on the importance of jute as a novel, eco-friendly, lightweight, cheap, available, and nontoxic material added to two strategies of BTMS. The setup was physically made and experimentally studied for the purpose of BTMS optimization.

Lithium-Ion cell ageing is sensitive to cell temperature. Previous studies have investigated ageing under adiabatic or controlled environmental temperature (i.e., isoperibolic) conditions. Notably, these conditions do not impose a uniform cell surface temperature (i.e., isothermal condition) or a controlled cooling rate, as an active Thermal Management System (TMS) would. This leads to a clear interdependence between charge/discharge rates and cell temperature, due to the uncontrolled cell temperature history. Consequently, the separate influence of these variables on the cell performance cannot be investigated. In this study, the ageing of a 300 mAh Lithium Cobalt Oxide (LCO Li-Ion) pouch cell under isoperibolic and isothermal conditions in the range of 0 °C - 40 °C is investigated. Each cycle comprises a CC-CV (constant current-constant voltage) charge of 1C and a CC discharge of 2C. Similar average ageing rates for isoperibolic and for isothermal conditions but at different reference temperatures were found. For example, an isoperibolic temperature condition of 25 °C yielded a similar degrading rate as an isothermal condition at 30 °C. This is mainly due to the effect of the cell self-heating (Joule heating) which increases the median operating temperature above that of the surroundings. These findings emphasise that uncontrolled cell thermal conditions lead to overall performance strongly dissimilar and randomly dependent on the transient heat transfer coefficient of isoperibolic TMS. Finally, an optimal isothermal condition that maximises the cell electrochemical efficiency and minimises its ageing is identified in the range of 25 °C-35 °C.
... This passive cooling technique is considered an effective and low-cost iso-thermalisation method.

Thesis
This thesis is concerned with the investigation of a novel concept targeting to couple the sectors of power generation and aviation in an ‘energy systems integration’ approach, in line with Europe’s strategic plans for climate neutrality by 2050. The developed approach is based on multi-fidelity computational studies spanning from zero- and one-dimensional models exploring the design space of a hybrid-electric aircraft and its thermal management system, to validated fluid dynamics simulations, as the first phase of component zooming (e.g. on the heat exchangers) development in this type of integrated systems. A set of research questions are posed about the feasibility of the integrated system and, the challenges occurring both in the underlying physics, as well as the models’ suitability are sought and discussed. A theoretical background discussing about advanced thermodynamic cycles and existing commonalities between hybrid, combined cycles is given to demonstrate how these can reduce the propulsion system’s irreversibilities, as representatives of its losses. A description of the multi-fidelity modelling is then given. To account for the hybrid-power generation unit, the work done employs higher fidelity models for the performance evaluation of land based thermal storage units with phase change materials. Two different layouts are examined, based on the selected temperature levels as a function of the power unit’s operating strategy. Three types of heat exchangers are examined, namely a finned shell and tube, a spiral coil, and a macro-encapsulated configuration. Regarding the latter, a novel macro-encapsulated configuration is proposed as a method for thermal energy storage and management, as part of a cooling/heating system intended for power generation. To account for the hybrid-propulsion unit, the work done employs lower fidelity models for the design space exploration of a hybrid electric aircraft, with electrical energy storage. Furthermore, a thermodynamic model is developed for the evaluation of the benefits in using fluids as coolant agents, for thermal management purposes and power augmentation at take-off. The hybrid-electric propulsion configuration is based on a novel series/parallel hybrid concept, with an electrically driven aft fan which takes advantage of the boundary layer ingestion concept. The following part presents the design of the thermal management system for the selected propulsive configuration, by also identifying its performance and overall sizing. It is shown that this part becomes the enabling system to allow for the integration of power and propulsion systems. An architecture is presented, considering the redundancy characteristics, to avoid critical engine failure modes. An error propagation analysis is included, to determine the impact of critical parameters in this system’s design. The final part includes a feasibility study about technical and economic aspects of concepts allowing the integration of a power and propulsion unit, using an on-board thermal energy storage. The main outcome indicates the potential of an on-board thermal storage unit, to save up to 20 kWh of energy for each flight, for the selected propulsive configuration. Moreover, the minimum requirements of this system are determined, to justify an investment for further research and development.
