“…Since the geometry of battery cells has been considered here in a stacked shape, the Aluminum sheet is arranged in between the battery cells of 100 mm × 100 mm × 15 mm with a cooling fin and two flow connector channels both in the inlet and outlet side of cooling fins. The coolant used in this method is water [64]. The coolant is pumped into the channels by a coolant pump from the inlet side and released through the outlet side.…”

The design of an optimized thermal management system for Li-ion batteries has challenges because of their stringent operating temperature limit and thermal runaway, which may lead to an explosion. In this paper, an optimized cooling system is proposed for kW scale Li-ion battery stack. A comparative study of the existing cooling systems; air cooling and liquid cooling respectively, has been carried out on three cell stack 70Ah LiFePO4 battery at a high discharging rate of 2C. It has been found that the liquid cooling is more efficient than air cooling as the peak temperature of the battery stack gets reduced by 30.62% using air cooling whereas using the liquid cooling method it gets reduced by 38.40%. The performance of the liquid cooling system can further be improved if the contact area between the coolant and battery stack is increased. Therefore, in this work, an immersion-based liquid cooling system has been designed to ensure the maximum heat dissipation. The battery stack having a peak temperature of 49.76 °C at 2C discharging rate is reduced by 44.87% to 27.43 °C after using the immersion-based cooling technique. The proposed thermal management scheme is generalized and thus can be very useful for scalable Li-ion battery storage applications also.

“…Compared with the original design, this strategy played a positive part in temperature distribution. Then, Varma et al [ 81 ] numerically analyzed reverse flow direction on battery thermal behavior and found that the Δ T max was reduced by 2.77 °C due to the redistribution of heat. Notably, a reasonable design in a liquid system is beneficial to control battery temperature behavior.…”

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 temperature of high-power lithium-ion batteries has a great influence on their performance, safety, and stability; thus the battery thermal management system (BTMS) is a key component of electric vehicles. In this paper, a novel liquid-cooling BTMS with a thin plate and a slender tube is proposed for prismatic batteries, four different cooling structures of the tube are designed to achieve a high temperature uniformity, and a three-dimensional numerical model is established. The effects of different cooling structures, battery discharge rates, coolant inlet velocities and inner diameters of the slender tube on the thermal performance are investigated. The results indicate that design S3, for which the length of the effective heat transfer tube distributed by each battery increases gradually along the flow direction of the coolant, exhibits the best thermal management performance among the four designed cooling structures, especially in terms of the temperature uniformity. When the inner diameter of the slender tube is 2 mm and the inlet velocity is not less than 0.5 m/s, the maximum temperature difference between the batteries is reduced to 4.23 C at a 2C discharge rate. This study can provide guidance for the structural design of BTMSs for prismatic batteries.
