“…In hybrid BTMS, the heat inside battery pack was first transmitted to outside through a heat pipe, while air cooling coupled with intermittent spray cooling further dissipated the heat at the high‐power case. In addition, Jang et al [ 176 ] designed a liquid cooling–heat pipe hybrid BTMS, aiming to improve the heat‐transfer efficiency. They compared the effect of heat pipe type on the cooling performance of BTMS.…”

The performance of lithium‐ion batteries is quite dependent on temperature and a series of investigations on the battery thermal management system (BTMS) have been reported during the past decades. Herein, the recent developments of BTMS are thoroughly summarized. First, the thermal characteristics of the battery caused by different temperature conditions and temperature nonuniformity are described. Then, the thermal models, including electro‐thermal coupled model and electrochemical–thermal coupled model are briefly presented. Subsequently, various traditional strategies like air cooling, liquid cooling, phase change material (PCM) cooling, and heat pipe cooling are elaborated. With the development of battery technology, BTMS based on a single strategy alone cannot meet the growth of thermal requirements, especially under dynamic and high‐power energy conditions. Hence, a hybrid BTMS that integrates two or more cooling strategies begins to be studied and provide a feasible solution for the problem. The related studies on hybrid BTMS are also systematically reviewed from the perspective of combinations, such as air–PCM, liquid–PCM, heat pipe–PCM, and other hybrid strategies. Besides, the current research on battery preheating strategies is also summarized. Finally, insufficient present studies are pointed out, aiming to provide comprehensive guidance toward the development of battery thermal management.

“…The researchers investigated the effects of a hybrid BTM system, which consists of passive cooling using HP and active cooling through the use of liquid. The researchers discovered that by utilizing this hybrid cooling method under optimal conditions, the T max can be reduced by 9.4 °C, and the T max of the battery can be maintained below 42 °C at discharging rate of 4 C. [ 44–47 ] It was also determined that the latent heat of CPCM could be increased by ≈27.5% when using this hybrid cooling method during a discharge rate of 2 C. Figure 15 shows the battery cooling arrangement using a HP with a cold plate. The fluid flows via a cold plate connected to the bottom of the prismatic battery, and HPs are attached along with the battery.…”

The lithium‐ion battery (LiB) is currently an essential part of electric vehicles (EVs). The popularity of LiBs among EV manufacturers is because of their long life, fewer memory effects, high specific energy density, and lightweight. However, temperature affects the LiB life and performance to a great extent. The burden on battery thermal management (BTM) is significantly increased by the need to increase battery capacity and decrease the battery charging time. Hence, reliable and effective BTM is the need of the hour. Herein, the current status of different battery cooling techniques has been discussed along with their merits and demerits. The main objective of this paper is to inform the readers and give them a clear understanding of various cooling techniques and their current status and highlight any novel approaches being used by the researchers to improve these cooling techniques. Future needs and opportunities in this field have also been discussed.

The heat dissipation capability of the battery thermal management system (BTMS) is a prerequisite for the safe and normal work of the battery. Currently, many researchers have designed and studied the structure of BTMS to better control the battery temperature in a specific range and to obtain better temperature uniformity. This allows the battery to work safely and efficiently while extending its life. As a result, BTMS has been a hot topic of research. This work investigates the impact of pin-fins on the heat dissipation capability of the BTMS using the computational fluid dynamics (CFD) approach, designs several BTMS schemes with different pin-fin structures, simulates all schemes for fluid-structure interaction, and examines the impact of different distribution, number, and shape of pin-fins on heat dissipation capability and pressure drop. Analyzing the effect of cooling plates with different pin-fins on the thermal capability of the BTMS can provide a basis for the structural design of this BTMS with pin-fin cooling plates. The findings demonstrate that the distribution and quantity of pin-fin shapes might affect heat dissipation. The square-section pin-fins offer better heat dissipation than other pin-fin shapes. As the pin-fins number increases, the maximum battery temperature decreases, but the pressure drop increases. It has been observed that uniform pin-fin distribution has a superior heat dissipation effect than other pin-fin distribution schemes. In summary, the cooling plate with a uniform distribution of 3 × 6 square section pin-fins has better heat dissipation capability and less power consumption, with a maximum battery temperature of 306.19 K, an average temperature of 304.20 K, a temperature difference of 5.18 K, and a pressure drop of 99.29 Pa.
