摘　　要：锂离子电池的高比能量、大输出功率以及低自放电率等一系列独有优势使其迅速成为电动汽车的重要核心。但是锂电池具有较高的温度敏感性,电池热管理系统对提高电池的效率、可靠性和安全性有着重要的作用。本文综述了近年来国内外主流的电池包热管理形式,包括自然冷却、强制风冷、液冷和相变冷却等。阐述了各种冷却散热方式的优缺点,针对电池热管理提出初步的分析讨论,为电池热管理系统的完善提出优化意见。Lithium-ion battery has a series of unique advantages such as high specific energy, large output power and low self-discharge rate, which makes it become an important core of electric vehicles. However, because of the high temperature sensitivity of lithium batteries, the battery thermal management system plays an important role in improving the efficiency, reliability and safety of batteries. In this paper, the main thermal management methods of battery pack in recent years, in-cluding natural cooling, forced air cooling, liquid cooling and phase change cooling, are reviewed. The advantages and disadvantages of various cooling methods are expounded, and the preliminary analysis and discussion are put forward for the battery thermal management system, and the opti-mization opinions are put forward for the improvement of the battery thermal management sys-tem.
