Recent Developments of Thermal Management Strategies for Lithium‐Ion Batteries: A State‐of‐The‐Art Review

Abstract

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.

Promotion of practical technology of the thermal management system for cylindrical power battery

“…Table 6 illustrates how the composite cooling strategy can create ideal combinations according to specific operational conditions. Through evaluating the pros and cons of four cooling techniques-air cooling, liquid cooling technology, PCM, and heat pipe-a new thermal conductive material was introduced, heat exchanger design was enhanced, and the cooling system's structure and parameters were optimized to achieve efficient heat dissipation (Liu et al 2022).. This approach enables automatic switching of the cooling mode based on battery temperature and load conditions, thereby enhancing system coherence and stability.…”

Optimized Design and Operation Control of Refrigerant Direct Cooling Thermal Management System for Power Battery

“…In recent years, with increasingly stringent greenhouse gas emission regulations being implemented, the development of new energy vehicles, represented by battery electric, plug-in hybrid, and fuel cell vehicles, is advancing. [1][2][3][4] Among these, electric vehicles have gradually gained popularity by their advantages in energy conservation, environmental friendliness, structural simplicity, and low noise levels. Consequently, the sales volume and ownership of electric vehicles are increasing year by year.…”
