“…However, a more detailed study also shows that for almost the same cooling performances, the zig-zag profile causes about 3 times larger pressure drops, proving it not to be the ideal solution to be implemented in the analyzed BTMS. Shen et al [79] propose a conventional cold plate structure beneath the prismatic batteries, but using refrigerant as coolant medium, and investigated the effects of different flow structures of the cold plate, presented in Figure 4b. The numerical calculations show that although the longer flow paths have a better cooling effect, the increase of the refrigerant's pressure drop is far more significant.…”

In the current context of transition from the powertrains of cars equipped with internal combustion engines to powertrains based on electricity, there is a need to intensify studies and research related to the command-and-control systems of electric vehicles. One of the important systems in the construction of an electric vehicle is the thermal management system of the battery with the role of optimizing the operation of the battery in terms of performance and life. The article aims to critically analyze the studies and research conducted so far related to the type, design and operating principles of battery thermal management systems (BTMSs) used in the construction of various shaped Li-ion batteries, with focus on cooling technologies. The advantages and disadvantages of the individual components, as well as of the proposed BTM solutions, are extensively investigated, with regard also to the adaptability of these systems to the different Li-ion battery shapes. The information thus synthesized provides the necessary and important information and proposes future directions in research to those interested in this topic to be used to increase the efficiency of the thermal management systems of the battery (and with it the global efficiency of the electric vehicle).

The paper presents the numerical optimization of an innovative radiator for use in electric buses in terms of energy consumption and noise emission. Computational fluid dynamics simulations were performed. The flow of the cooling medium was modeled using the RANS method. The two-equation k-ɛ turbulence model, the heat transfer model and the acoustic model were used. According to the research results, the separation of the air stream in individual fan sections con-tributes to the improvement of energy efficiency and reduces noise emissions. As a result of the simulation, it was found that the best solution in terms of noise emission as well as the occurring flow phenomena caused about a 2 dB decrease of maximum values of the noise level and allowed the equalization of the cooling medium velocity (prevailing velocity range between 4 and 9 m/s). The results of the simulations were verified under laboratory and field conditions, showing a very good convergence of the model with the results of the experiments (i.e. the maximum noise level was estimated at 57 dB, under measurement conditions for the same operating point at 59 dB) while maintaining the baseline energy demand, which indicates a new approach in the method of shaping internal elements of electric vehicle coolers.

The dynamic development of electromobility poses challenges to designers regarding not only the efficiency of energy transformation but also the battery life, which is influenced by the stability of its operating temperature. Designing cooling systems is connected not only with the optimization of energy management but also with other environmental parameters, such as noise emission. The paper presents the numerical optimization of an innovative radiator for use in electric buses in terms of energy consumption and noise emission. The results of the numerical studies were verified in laboratory and field conditions, showing a very good convergence of the model with the results of the experiments.
