The invention provides a multi-mode temperature management system of an electric automobile. The system comprises an air conditioning system, a power battery temperature management system and a driving motor temperature management system, wherein the air conditioning system can independently heat and refrigerate a compartment, the power battery temperature management system can independently heata power battery, and the driving motor temperature management system can independently cool a driving motor. The multi-mode temperature management system is advantaged in that communication and disconnection among the air conditioning system, the power battery temperature management system and the driving motor temperature management system are controlled through pipelines and valves, power battery temperature management modes are dynamically switched according to the real-time temperature of a power battery, the driving motor temperature management modes are dynamically switched according tothe real-time temperature of a driving motor, the temperature management modes are more flexible, energy utilization efficiency is higher, and temperature control is more stable.

    本发明提供了一种电动汽车多模式温度管理系统,包括空调系统、动力电池温度管理系统、驱动电机温度管理系统,所述空调系统可以独立地对车厢进行制热和制冷,所述动力电池温度管理系统可以独立地对动力电池进行加热,所述驱动电机温度管理系统可以独立地对驱动电机进行降温。本发明的电动汽车多模式温度管理系统通过管路与阀门控制空调系统、动力电池温度管理系统和驱动电机温度管理系统之间的连通与隔断。本发明的电动汽车多模式温度管理系统根据动力电池的实时温度动态切换动力电池温度管理模式,以及,根据驱动电机的实时温度动态切换驱动电机温度管理模式,温度管理模式更加灵活,能量利用效率更高,温度控制更加稳定。
