摘要

新能源汽车热管理系统是保证热安全和热舒适性的关键，而电池热管理和

乘员舱冷却强耦合，造成动态特性差。为此，本文针对某跨临界CO

汽车热管理系统进行研究，基于热舒适性与电池温度协同控制方法，通过在Amesim中搭建热管理系统及控制模型，对不同应用场景和工况下的热管理系统进行仿真分析，并与传统基于乘员舱温度的控制方法进行对比。结果表明：该热管理系统在各工况下能够迅速将乘员舱热环境和电池温度稳定在适宜范围，并具有良好的稳定性和较快的恢复速度，具有很好的抗扰动效果；同时与传统基于乘员舱温度的控制方法相比能够始终使乘员舱具有极好的热舒适性，验证了基于该控制方法的热管理系统的优越性。

Abstract

The thermal-management system of a new energy vehicle is a key to ensuring thermal safety and comfort. Battery thermal management and cabin cooling are strongly coupled

resulting in poor dynamic characteristics. Thus

this study examined a transcritical CO

vehicle thermal-management system

built an Amesim model of a thermal-management system and control system based on the co-control of thermal comfort and battery temperature

and analyzed the thermal-management system under different scenarios and conditions. It was demonstrated that the thermal-management system was able to quickly achieve a comfortable thermal environment of the cabin and ensure a suitable battery temperature under various conditions

with less fluctuation

prompt response

and excellent anti-disturbance performance. Compared to the traditional control method based on cabin temperature

this method could provide excellent cabin thermal comfort at all times

which verified the superiority of a thermal-management system based on this control method.
