[0101] When the heat pump system heats the battery, the battery heating circuit on the coolant side and the battery heating circuit on the refrigerant side work simultaneously, and the valve between the second port and the third port of the first five-way valve 17 is opened, the valve between the fourth port and the fifth port of the first five-way valve 17 is opened, the valve between the second port and the third port of the second five-way valve 14 is opened, and the valve between the fourth port and the fifth port of the second five-way valve 14 is opened. The battery heating circuit actively generates heat through the motor, and under the coupling of the refrigerant side and the coolant side, the water heating PTC19 and the drive system actively generate heat to heat the battery together, thereby realizing the complementary use of heat among multiple systems and saving energy consumption.

[0102] It can be seen from the above embodiments that this embodiment can realize the structure of water-cooled condenser 21 + low-temperature radiator 1 in parallel with the drive system cooling, and set up an independent water pump for the drive system cooling circuit to reduce interference between systems and avoid over-temperature restriction of drive system components.

[0103] The present application provides a vehicle, which includes the vehicle thermal management integrated architecture as described above.

[0104] The above-mentioned vehicle thermal management integrated architecture is suitable for vehicles with ultra-fast charging function. Without changing the technical route of direct heat pump air conditioning, the water-cooled condenser 21 is reused, which can not only actively generate heat to heat the battery when the heat pump absorption motor actively generates heat, but also improve the refrigeration performance of the air-conditioning system when the battery needs heavy load cooling.

[0105] It can be seen from the above embodiments that the embodiments of the present application can achieve connectivity between any two ports through two five-way valves of the same structure, thereby reducing the development cycle and cost of components, and through the coordinated use of two identical five-way valves, the heat pump air conditioner, drive system and battery module 18 are strongly coupled, achieving complementary utilization of heat from multiple systems and achieving the effect of saving energy.
