The invention provides an integrated thermal management system, a control method and an electric vehicle. The system comprises a heat pump refrigerant cycle, a cabin heating cycle, an electric drive cooling liquid cycle and a battery cooling liquid cycle. The heat pump refrigerant cycle comprises a compressor, a water condenser, a first electronic expansion valve, an outdoor heat exchanger, a fan, a second electronic expansion valve, an evaporator, an air blower, a third electronic expansion valve and a gas-liquid separator. The cabin heating cycle comprises a first water pump, a three-way valve, a first heater and a heater core. The electric drive cooling circulation comprises a second water pump, an electric drive system, a radiator, an auxiliary water tank and a five-way valve. The battery cooling circulation comprises a third water pump, a power battery, a second heater, a switch valve and a cooling-water machine. Multi-level waste heat recovery can be carried out at the low temperature, the battery, the electric drive and the cabin are fully cooled at the same time at the medium temperature and the high temperature, and various heat management requirements are met with low energy consumption under different environment temperatures and vehicle running conditions.
