Integrated thermal management system and vehicle

An integrated heat management system, comprising:

• a heat pump subsystem, configured to heat or cool a passenger compartment of a vehicle, and configured to exchange heat with a battery of the vehicle;
• a high-pressure cooling subsystem, configured to exchange heat with a high-pressure system of the vehicle and the heat pump subsystem;
• a battery self-heating subsystem, configured to heat the battery through charging and discharging of the battery;
• an air heating subsystem, configured to heat the passenger compartment;
• and
• the heat pump subsystem comprising a compressor and a control valve, one end of the control valve being in communication with an exhaust port of the compressor, and another end of the control valve being in communication with an air return port of the compressor or being in communication with the air return port of the compressor through a gas-liquid separator,
• wherein the control valve is controlled to be in communication with the exhaust port of the compressor and the air return port of the compressor, to implement air supplement and enthalpy increase,
• wherein the battery self-heating subsystem comprises:
• a battery, the battery comprising a first battery pack and a second battery pack, a negative electrode of the first battery pack being connected to a positive electrode of the second battery pack at a connection point, the connection point being a first node;
• an inverter circuit, a positive direct current terminal of the inverter circuit being connected to a positive electrode of the first battery pack, and a negative direct current terminal of the inverter circuit being connected to a negative electrode of the second battery pack;
• and
• a drive motor, a three-phase winding of the drive motor being correspondingly connected to a three-phase alternating current terminal of the inverter circuit, and a neutral point of the three-phase winding being connected to the first node through a controllable switch,
• wherein:
• in response to determining to heat the battery by using the battery self-heating subsystem, the controllable switch is controlled to be in a turn-on state, and on/off control on the inverter circuit is performed, to perform alternate oscillation heating on the first battery pack and the second battery pack through the three-phase winding.
