The invention provides a temperature control device, a control method thereof and an electric vehicle. The device comprises a control unit, a passenger compartment thermal load detection unit, a compressor, a condenser, a battery management system (BMS), a passenger compartment air conditioning system and a power battery cooling system. The compressor, the condenser and the passenger compartment air conditioning system form a first closed loop, the compressor, the condenser and the power battery cooling system form a second closed loop, and a refrigerant circulates in the first closed loop andthe second closed loop; a first electronic expansion valve is arranged on a pipeline, connected with the condenser, of the passenger compartment air conditioning system, and a second electronic expansion valve is arranged on a pipeline, connected with the condenser, of the power battery cooling system. The control unit receives and determines the rotating speed of the compressor according to thepassenger compartment thermal load data of the passenger compartment thermal load detection unit and the battery thermal load data of the battery management system, adjusts the opening degree of the first electronic expansion valve and the opening degree of the second electronic expansion valve, and cools the battery and the passenger compartment.
