The invention relates to an electric vehicle thermal management system and a vehicle, and belongs to the field of electric vehicle thermal management. The electric vehicle thermal management system comprises a steam compression circulation loop and a cooling liquid circulation loop, the loops are mutually coupled, and coupling thermal management can be carried out on a passenger compartment, a battery pack, a driving motor, an inverter, a charger and an electric control unit in the system. A three-way valve, a four-way valve and a throttling valve in the system can enable system loops to be coupled and switched according to different heat management strategies, and therefore refrigerating/heating of a passenger compartment is achieved. Radiating/heating the battery pack; an electric controller, a motor, an inverter and a charger dissipate heat; waste heat recovery; heating at low temperature; defrosting in winter and the like. The thermal management system of the electric automobile is compact in structure, complete in function, high in energy utilization rate and capable of effectively meeting the thermal management requirements of the electric automobile at various environment temperatures.
