The present invention discloses a thermal management system, a control method therefor, and a vehicle. The thermal management system includes a compressor, an outdoor heat exchanger, a gas-liquid separator, a heater core, a traction battery, an electric drive component and an integrated thermal management unit. The integrated thermal management unit includes a flow channel plate, a pump assembly, a valve assembly, a water-cooling condenser, a water-water heat exchanger and a battery cooler. In a first operating mode, the compressor and a heating water pump are started, a battery water pump and/or a motor water pump are started, and the valve assembly is in a first preset state; the valve assembly connects a coolant output of the battery cooler with an inlet of the motor water pump, and connects an inlet of the battery water pump with an outlet of the electric drive component, and the valve assembly further connects an inlet of the heating water pump with an outlet of the heater core. In this way, waste heat generated by the traction battery and the electric drive component can be collected and conveyed to the battery cooler and also used to evaporate a coolant, so as to heat a passenger compartment by using the waste heat, and improve the energy utilization rate. |
