The invention provides a thermal management system, a thermal management method and an electric vehicle. The thermal management system comprises an air conditioner refrigerant loop and a secondary refrigerant loop. The air conditioner refrigerant loop comprises a compressor, an enthalpy increasing device, a first heat exchanger and an intermediate heat exchanger. The secondary refrigerant loop comprises an adjusting branch, a battery branch, a motor branch and an out-vehicle branch, the out-vehicle branch comprises a first pipeline and a second pipeline which are connected in parallel, an out-vehicle heat exchanger is arranged on the first pipeline, the first end of a secondary refrigerant heat exchange pipeline can selectively communicate with the first pipeline or the second pipeline, the second end of the secondary refrigerant heat exchange pipeline can selectively communicate with the adjusting branch or the motor branch, and the adjusting branch, the battery branch, the motor branch and the out-vehicle branch are connected through a first four-way valve. The enthalpy increasing device is connected to an air supplementing opening of the compressor through an air supplementing pipeline. According to the thermal management system, thermal energy of the whole vehicle can be reasonably distributed, the energy utilization rate of the whole vehicle is increased, and the endurancemileage is increased.
