“…The cooling system's performance is evaluated based on the battery peak temperature and the homogeneity of the temperature distribution within the battery. The most important concluding remarks of this case study can be listed in the following points: The propane based cooling system can maintain the battery temperature within the acceptable operating temperature range, proving that it has effective cooling performance. When 5% of the battery is immersed into the saturated liquid propane at a pressure of 8.5 bar, the maximum battery temperature is kept below 39°C for the charging and discharging cycles. As the cooling propane covers the higher portion of the battery pack, the peak battery temperature gets lower. When 30% of the battery is immersed in the saturated liquid propane, the peak battery temperature is lower than 34°C. When the saturated propane's pressure is increased from 8.5 to 10 bar, the temperature difference across the battery is reduced significantly. On the other hand, increasing the saturated propane pressure from 8.5 to 10 bar increases the peak battery temperature, which is undesirable. …”

With increasing worldwide population and rising standards of living, the global energy consumption is increasing at significant rates. Together with climate change concerns and negative impacts of fossil fuel use, the need for clean and smart energy systems is becoming more obvious. Clean and smart systems provide energy to all types of end‐use applications in an environmentally friendly, affordable, reliable, and efficient manner. Heat losses are recognized as some of the most significant causes of efficiency degradation in energy systems. Therefore, this study overviews and investigates current and future thermal management options for different end‐use purposes for a more sustainable future. In this study, a smart approach is taken when evaluating existing and emerging thermal management systems and smart targets are introduced for better thermal management systems. In addition, some novel thermal management systems for various applications such as electric/hybrid vehicles, power systems, and industrial processes are introduced as case studies and the energy and exergy efficiencies of these case studies are compared. In addition, some key future directions are provided in terms of better thermal management options for a sustainable future. The case study results of this study show that with better thermal management strategies, it is possible to reach energy and exergy efficiencies up to 60% and 50%, respectively in hybrid vehicles, industrial processes, and robotic applications.

“…In addition to the cabin thermal comfort issue, the battery and motor for achieving high energy and high power would generate a large amount of waste heat during EV driving . Without timely removal of waste heat, electronics thermal runaway would occur, and overheat would bring about a fire . Therefore, the waste heat should be removed in time in view of practice and the economy .…”

Summary Electric vehicle thermal management system (EVTMS) is a promising method to solve cabin thermal comfort and electronics waste heat. In this paper, an integrated EVTMS combining heat pump, battery cooling, and motor waste heat recovery was proposed. EVTMS performance tests were firstly carried out in the environment chamber with variations of refrigerant charge, electronic expansion valve (EXV) opening, compressor speed, environmental temperature, and waste heat amount. Moreover, the comprehensive energy, exergy, and thermo‐economy analyses for EVTMS were performed based on the experimental results. The results demonstrate that the optimum refrigerant charge for baseline EVTMS is 810 g, and the optimum EXV opening is in the range of 70% to 90%. Accordingly, the percentage of cooling capacity reduction (PCCR) and the percentage of waste heat recovery (PWHR) are in the range of 26.3% to 32.1% and 18.73% to 45.17%, respectively. The exergy destruction ratio of the scroll compressor and external heat exchanger is more than 80%. With the utilization of the proposed EVTMS, the operation cost per hundred kilometers for heating mode is decreased 20.83% compared with that of positive temperature coefficient heaters.

In this paper, the electrochemical‐thermal characteristics are studied by using 2D (two‐dimensional) axisymmetric multi‐physics model coupled with a 1D (one‐dimension) model to study thermal safety of the 18650 lithium‐ion battery with various cathode materials. LiCoO2 (LCO), LiFePO4 (LFP), LiMn2O4 (LMO), LiNi0.8Co0.15Al0.05O2 (NCA) and LiNi1/3Co1/3Mn1/3O2 (NMC) materials have been modeled about their temperature change in different charge/discharge rates. Also, battery with identical cathode material under various charging and discharging ratio is studied about the temperature safety. The simulation results showed that the temperature roughly increases by 5 degrees with the ratio of each increment of 2C for an identical material. Under the 10C ratio, the highest temperature of LiFePO4 and LiNi0.8Co0.15Al0.05O2 is 63.6 oC and 63.8 oC respectively, which means they have the best thermal stability and thermal safety. Among the five positive electrode materials, the thermal stability of LiFePO4, LiNi0.8Co0.15Al0.05O2, LiMn2O4, LiNi1/3Co1/3Mn1/3O2 and LiCoO2 decreased successively. The influence of different materials and charge/discharge ratio on the thermal behavior of the battery was analyzed and discussed. The simulation results are similar to the prediction results, but it can get the visualized results in principle with the advantage of shorter time, which is instructive to vast researchers.
