摘　　要：热泵系统作为新能源车辆热管理的关键技术之一,其性能直接影响到车辆的能耗和驾驶者的体验。本文聚焦新能源汽车热泵系统中的多模式热量获取控制策略,通过优化热泵的运行模式选择,实现在不同工况下的水温需求,同时确保系统的能量消耗达到最低。在详细分析新能源车辆热泵系统工作原理的基础上,以焦耳空调为例构建了一个包含多个热源的热泵模型,提出一套基于传热单元数法的实时数据和预测模型的智能控制算法,以实现在各种气候条件和车辆运行状态下的热泵系统高效管理。As one of the key technologies for thermal management of new energy vehicles,the performance of heat pump system directly affects the energy consumption of the vehicle and the driver's experience.This paper focuses on the multi-mode heat acquisition control strategy in the heat pump system of new energy vehicles,which realizes the water temperature demand under different working conditions by optimizing the operation mode selection of the heat pump,and at the same time ensures that the energy consumption of the system is at a minimum.Based on a detailed analysis of the working principle of the heat pump system in new energy vehicles,a heat pump model containing multiple heat sources is constructed using Joule air conditioning as an example,and a set of intelligent control algorithms based on real-time data and prediction models of the number of heat transfer units method is proposed to achieve efficient management of the heat pump system under various climatic conditions and vehicle operating states.
