基于高速工况的电池包散热能力研究

Research on the Cooling Capacity of Battery Pack Based on the Highway Fuel Economy Test

利用Advisor软件搭建纯电动汽车模型,在高速工况(Highway Fuel Economy Test,HWFET)下对纯电动汽车进行动态仿真分析,得出此工况下动力电池的输出电流分布。使用现有的试验条件求得动力电池产热量曲线,并以此作为电池仿真分析的热源模型。利用流体动力学软件STAR-CCM+分析纯电动汽车在HWFET工况下运行时,动力电池包的散热能力。

A model was built and dynamic simulations were conducted by using Advisor for pure electric vehicles under high-speed conditions. The distribution of output current of the battery was obtained. Then the heat production curve of the battery was measured and used as a heat source in the model. Finally,the paper analyzed the cooling capacity of the battery pack by STAR-CCM＋ for pure electric vehicles running under high-speed conditions.
