摘要
采用强制风冷的方案,对世博燃料电池插电式混合动力微型车40A.h磷酸铁锂动力电池系统进行了热管理的结构设计和性能研究.详细分析了动力蓄电池的散热需求,在此基础上,结合整车布置,完成了热管理系统的结构设计,并对设计结果进行了数值模拟.将设计方案制作成实体样品,分别在不同的环境温度下,以一定的电流工况对电池加载,测试电池系统的温升情况.最后,对世博运营过程中具有代表性的两日测试数据进行了分析.仿真计算结果、测试试验结果以及实车数据分析结果均表明,设计方案在电池系统温升控制和电池单体温度一致性控制方面都达到了预期的需求.
This paper focuses on the structural design and performance study of the thermal management of 40 Ah LiFeP04 battery systems for Expo plug-in fuel cell vehicles by using the forced air cooling. Based on a detailed analysis on the thermal requirements of battery, and consideration of the layout of the vehicle, this paper presents a structural design and a simulation of the thermal management system. Then the tests on the temperature rise of the battery system sample based on the structural design were done under certain current cycle in different temperatures. Finally, an analysis was made of a two-day testing data, the most typical of Expo.Simulation and experiment results and road data analysis indicate that the design meet the expected requirements on temperature-rising control of battery system and the uniformity of cells temperature.
