 Lithium ion batteries, LIBs, are an important energy source for new energy vehicles, NEVs. However, they are highly sensitive to temperature, making it difficult to manage their thermal performance. A high-performance battery thermal management system, BTMS, is necessary to ensure efficient and secure operation. This paper reviews the effects of temperature on the performance of individual batteries and battery systems, as well as the current state of the art in liquid dash, PCM dash, and air-based BTMS. It also explores the integration of these systems with the vehicle thermal management system, VTMS, to maximize the use of the heat generated by the vehicle. Finally, the challenges and potential future developments of BTMS are discussed. This article was authored by Wenzhou Li, Yuhang Zhou, Haonan Zhang, and others.
