摘　　要：近年来,由于全球汽车数量的急剧增加,以汽油或柴油作为能源的传统汽车导致了严重的大气污染以及能源枯竭等问题,研发出实用的清洁能源汽车已经迫在眉睫。电动汽车的性能取决于动力电池组,电池组的工作温度对电池的性能影响极大,需要对电池组进行热管理。选取某型锂离子电池为研究对象,以强制风冷散热方式,使用CFD仿真软件对电池组进行2C放电状态下温度场仿真分析,通过比较两种电池组进出风口位置的温度场的最高温度以及温差以选择较优的一种电池组结构。The performance of an electric vehicle depends on the power battery pack. The working temperature of the battery pack has great influence on the performance of the battery,so it is necessary to manage the heat of the battery pack. Taking a kind of lithium-ion battery as the research object,and the forced air cooling method is used to simulate the temperature field of the battery under the condition of 2 C discharge by CFD simulation software. Comparing the maximum temperature and the temperature difference of the temperature field in the inlet and outlet of the two kinds of batteries,a better battery structure is selected.
