“…Prior to design and modeling, the parameters of the thermal management system must be determined or optimized. These parameters optimization include air velocity in the forced air cooling, − the ambient temperature in the forced air cooling, the flow rate of the liquid, − and cooling liquid temperature. − Some studies have proposed optimization using the ML method, which is considered to be an excellent tool for optimizing and predicting parameters. − Researchers attempted to implement ML models, such as artificial neural networks (ANNs), convolutional neural networks (CNNs), long short-term memory (LSTM), deep reinforcement learning (DRL), etc., to assist the BTM system for enhanced battery thermal safety and resilience. For example, Jaliliantabar et al developed an ANN model for the prediction of LIB temperature equipped with BTMs and proved the capability of ANN to predict battery temperature in various operating conditions of BTMs.…”

Due to strict regulations and the requirement to reduce greenhouse gas emissions, electric vehicles (BEVs) are a promising mode of transportation. The lithium battery is the most important power source for an electric vehicle, but its performance and life are greatly restricted by temperature. To ensure the safety of automobile operation and alleviate mileage anxiety, it is urgent to understand the current situation and predict the development and challenge of battery thermal management system. This work reviews the existing thermal management research in five areas, including cooling and heating methods, modeling optimization, control methods, and thermal management system integration for lithium batteries. Battery thermal management types include air-based, liquid-based, PCM-based, heatpipe-based, and direct cooling. Designing a better battery thermal management system not only needs to be optimized using algorithms on the model but also it uses intelligent algorithms for precise control to achieve safety and reduce energy consumption. This work also reviews the differences in thermal management systems between square and cylindrical batteries and summarizes the development trend of modularity in battery thermal management systems.

The rated temperature and its uniformity of lithium‐ion (Li‐ion) battery (LIB) pack are the main demands for safe and efficient operation. This paper investigates an air cooling system of a pack of five prismatic LIB's generating considerable heat through discharging energy. The cooling system is a three‐dimensional channel with flexible baffles of different arrangements installed on the walls of the channel to lower and regulate the temperature of the batteries. Three arrangements of these baffles are studied, transverse; L‐shaped and staggered. The study is formulated as turbulent fluid–structure interaction and solved numerically using the finite elements method. The study was conducted for five spaces between batteries, S = 0, 1, 2, 3 and 4 mm and three different inlet air velocities, Uin = 0.5, 1 and 2 m/s. It was found that the flexible baffles guide the coolant towards the batteries smoothly with less pressure drop and this significantly improves the performance of the battery thermal management system due to the reduction of the maximum temperature and temperature variation as well. The staggered arrangement of the baffles shows the most effective configuration, where the maximum temperature difference between batteries is only 1.85°C for S = 1 mm and Uin = 2 m/s.

“…[11] Kausthubharam et al observed that relocating the air inlet and outlet from the central position enhanced temperature uniformity, while air velocity increasing resulted in a decrease in maximum temperature. [12] In comparison to air-cooling systems, liquid-cooling systems exhibit enhanced capacity; however, they may also present potential leakage issues. [13] Sheng et al [14] investigated the thermal management performance (TMP) of BTM using a serpentine-channel liquid-cooling plate heat exchanger.…”

Liquid‐cooling techniques are commonly employed for battery thermal management (BTM) in commercial vehicles and energy storage applications, typically incorporating a cooling plate positioned beneath the casing of the battery pack. However, this heat transfer structural design results in smaller temperature drop in the terminal batteries located distantly from the plate, leading to an increased temperature difference. The integration of supplementary media into BTM systems holds the potential to enhance thermal management performance, thereby offering a viable solution to this issue. Herein, a fan is incorporated into the liquid‐cooling system to induce air circulation and augment convective heat transfer onto the battery surface. In the findings, it is revealed that the implementation of a reverse airflow path beneath the cooling plate result in a temperature decreasing rate of 0.59 K min−1, indicating a notable enhancement of 23% compared to solely employing a liquid‐cooling configuration. In the results, it is demonstrated that 1) reducing the inlet temperature can effectively enhance the rate of temperature reduction and 2) increasing the fan speed can reduce the temperature difference and promote temperature uniformity. In conclusion, in this present study, comprehensive guidelines and references are provided for the future design of BTM.
