An electric tractor integrated thermal management system and a control method are disclosed. The system comprises a power battery thermal management system, a motor thermal management system and an air conditioning system; the power battery thermal management system is connected with the air conditioning system through a battery heat exchanger, and the motor thermal management system is connectedwith the air conditioning system through an out-cabin heat exchanger; the control method comprises a power battery, motor and in-cabin temperature control method and a power battery thermal managementsystem control method during tractor charging. The power battery real-time temperature Tb, the in-cabin real-time temperature Tc and the real-time temperature Te of the motor, which are measured by atemperature sensor, are used as identification parameters by setting the temperature ranges of the power battery, the cabin and the motor; a tractor integrated thermal management system mode is adjusted in accordance with the tractor state; the power battery, the motor and the cabin are all at proper temperature, battery energy consumption is reduced by recycling waste heat of the motor, operation efficiency of a tractor is improved, and continuous operation time of the tractor is prolonged.
