“…By utilizing a compartment priority control strategy and a series connection, they were able to effectively control the temperature rise of both the battery pack and cabin. Lian et al [38] proposed an integrated architecture of BTMS based on R134a, which included a heatingcooling dual circuit and achieved efficient operation by controlling the refrigerant pressure and superheat level. The authors showed that this system was capable of maintaining the battery temperature below 46 °C, and could reach a battery heating rate of 49.20 °C min À1 during operation.…”

In order to solve the compatibility problem of lithium batteries thermal management and cabin comfort in electric vehicles, a refrigerant direct cooling thermal management system is designed in this article, which is expected to balance the temperature demands of entire vehicle at different driving conditions. A one‐dimensional model is established to investigate the system performance, whose accuracy has been verified by the testing bench of a prototype fixed with a 16‐battery module. By the aid of this model, the thermal characteristics of the battery pack and the passenger cabin are obtained, and the compressor speed as well as the valves are selected as control units by sensitivity analysis of the important components. Subsequently, detailed control strategies around the variable frequency of compress speed and switch regulation for the valves are proposed based on the temperature changes, torque, and operating power consumption of the system in different control modes. Under the test conditions of the global light‐duty vehicle test procedure, it is found that cabin temperature can be quickly stabilized about 26 °C under different ambient temperatures. Additionally, the battery pack can be effectively maintained within the safe operating temperature range of 20–40 °C.

“…They emphasized the need for effective battery management systems to dissipate heat and highlighted methods such as phase change materials and liquid cooling as promising solutions for future research. Currently, various cooling types have been employed in BTMS such as air cooling, [22,23] liquid cooling, [18,21,[24][25][26][27][28] refrigerant cooling, [28,29] heat pipes, [30,31] and phase-change material cooling. [17,[32][33][34] Among these methods, the liquid cooling approach is widely used because of its high specific heat capacity, good thermal conductivity, and low cost.…”

To design an effective battery thermal management system, multiple simulations with different levels of modeling, physics, and details are generally needed. However, complex and high‐resolution models are time‐consuming, both in terms of buildup and in computation time. Especially the fast‐moving early‐stage development phases demand all‐in‐one model approaches allowing for quick and efficient concept evaluations. To meet these requirements, herein, a lumped‐mass modeling approach is proposed and a methodology for evaluating various liquid cooling plate topologies is derived. The framework aims to assist the volatile concept phase of battery system development in providing multidimensionally optimized cooling plate topologies. A novel modeling strategy preselects plate parameters using a reduction procedure that couples the transient models’ accuracy with the steady‐state models’ computation time advantages. The results analyze different initial battery geometries, indicating significant deviations in their optimized cooling plate properties. Plate topologies are varied between their main construction design parameters: tube size and tube‐to‐tube distance. In addition to battery's mean temperature, further meaningful parameters like resulting volume flow are evaluated, compared, and discussed for the entire set of battery geometries. Subsequent sensitivity analyses show geometry‐related optimal plate topologies depending on the cooling circuit performance, stressing the necessity for early‐stage cooling plate investigations.
