摘　　要：锂电池由于其出色的电化学性能被广泛应用于纯电动汽车,温度是影响锂电池储电和安全的主要因素,在温度过高下工作导致电池性能快速衰退,甚至引发热失控。文章基于锂电池储电机理,分析了温度及其他影响因素,对比研究电池散热管理各方式特点,为电动汽车散热系统的选择和研发工作提供参考。Lithium batteries are widely used in pure electric vehicles due to their excellent electrochemical performance. Temperature is the main factor affecting the storage and safety of lithium batteries. Working at high temperatures leads to rapid decline in battery performance and even thermal runaway. This article analyzes the temperature and other influencing factors based on the principle of lithium battery storage motors, and compares and analyzes the characteristics of various methods of battery heat management to provide a reference for the selection and research and development of heat dissipation systems for electric vehicles.
