摘要: 为保证纯电动汽车在夏季高温情况下,热管理系统可以在合适的温度范围内高效稳定 工作,文章针对某款新能源纯电动汽车进行了不同的冷却方式研究。在实时道路工况的基础 上,采集实时数据,包括环境温度、车速、电池与电机的温度等,通过一维模型进行仿真分 析并通过实验验证。仿真结果表明,空调出风口、电池与电机三个位置最大误差分别为 5.1%、 3.5%与 4.6%。之后对冷却方式进行了优化对比分析,结果发现,主动式冷却方式较被动式冷 却方式可以将电池、电机与电控温度的冷却提升至少 10%以上,对热管理系统的实际研发工 作具有参考价值。

Abstract: In order to ensure that battery electric vehicle can work efficiently and stable within the right temperature range in the case of high temperatures in summer, different cooling mode are conducted for a new energy battery electric vehicle in this paper. On the basis of real-time road conditions, real-time data is collected, including ambient temperature, speed, battery and motor temperature, etc., and analyzes it through a one-dimensional model. The simulation results show that the maximum errors in the three positions of air conditioning outlet, battery and motor are 5.1%, 3.5% and 4.6%, respectively. After that, the cooling mode is optimized, and the comparative analysis finds that the active cooling mode can increase the cooling of the battery, motor and electronic control temperature by at least 10% compared with the passive cooling mode, which has reference value for the actual research and development of the thermal management system.
