The invention relates to the technical field of thermal management of vehicles, and discloses a whole vehicle thermal management system of an electric vehicle and a control method of the whole vehicle thermal management system. An outlet of the in-cabin heat exchange piece is communicated with one of the heat exchange inlets of the waterway evaporator and the in-cabin evaporator; the motor drives the heat exchange assembly, an inlet communicates with at least one of a heat exchange outlet of the in-cabin heat exchange piece, a heat exchange outlet of the water path evaporator and a heat exchange outlet of the water path condenser, and an outlet communicates with at least one of a heat exchange inlet of the water path condenser and an inlet of the in-cabin heat exchange piece. An inlet of the battery heat exchange piece is communicated with a heat exchange outlet of the waterway evaporator; and an outlet of the heat dissipation water tank is communicated with one of an inlet of the motor-driven heat exchange assembly and a heat exchange inlet of the water path evaporator. According to the whole vehicle thermal management system of the electric vehicle, the running efficiency of the whole vehicle is improved, the running reliability of the system is improved, the endurance mileage of the electric vehicle is increased, and the electric vehicle runs safely.
