This article provides a comprehensive summary of the recent developments in Battery Thermal Management System (BTMS), including battery thermal characteristics, thermal models, and various traditional strategies. With the advancement of battery technology, hybrid BTMS has emerged as a feasible solution to meet the increasing thermal requirements. The research on battery preheating strategies is also summarized, as well as the identified shortcomings in current studies.
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.
