The invention provides a heat management system of an electric automobile. The heat management system comprises a water heating heat exchange system, a refrigerant heat exchange system, a motor electric control heat exchange system and a battery heat exchange system. The water heating heat exchange system is provided with an in-vehicle second heat exchanger used for heating a passenger compartment. The refrigerant heat exchange system is provided with an in-vehicle first heat exchanger used for refrigerating or heating a passenger compartment. The motor electric control heat exchange system and the battery heat exchange system are respectively in thermal coupling with the refrigerant heat exchange system, and the battery heat exchange system is in thermal coupling with the water heating heat exchange system. Refrigeration and heating are conducted through the in-vehicle first heat exchanger, heating is conducted through the in-vehicle second heat exchanger, heating can be conducted through the in-vehicle first heat exchanger when the heating requirement is low, and mixed heating is conducted through the in-vehicle first heat exchanger and the in-vehicle second heat exchanger running at low power when the heating requirement is common. And when the heating requirement is high, heating can be conducted through the second heat exchanger in the vehicle running at high power, the refrigerating and heating requirements of a user can be met, and energy consumption can be reduced.
本发明提供一种电动汽车热管理系统,其中包括:水暖换热系统、冷媒换热系统、电机电控换热系统和电池换热系统;水暖换热系统设置有车内第二换热器,用于为乘员舱制热;冷媒换热系统设置有车内第一换热器,用于为乘员舱制冷或制热;电机电控换热系统和电池换热系统分别与冷媒换热系统热耦合,电池换热系统与水暖换热系统热耦合。本发明中通过车内第一换热器进行制冷和制热,通过车内第二换热器制热,在制热需求较低时可以通过车内第一换热器进行制热,在制热需求一般时通过车内第一换热器和低功率运行的车内第二换热器混合制热,在制热需求较高时可以通过高功率运转的车内第二换热器进行制热,不仅能满足用户的制冷和制热需求,又能降低能耗。
