The invention discloses a whole-vehicle thermal management system of a pure electric vehicle and a control method of the whole-vehicle thermal management system, and relates to the technical field of thermal management. Comprising a power battery system cooling loop, an electric drive system cooling loop and a passenger compartment heating loop, and the power battery system cooling loop and the electric drive system cooling loop are connected with a cooling liquid pipeline through a three-way electromagnetic valve and a second one-way valve; the passenger compartment heating loop and the electric driving system cooling loop are connected with a cooling liquid pipeline through a two-way electromagnetic valve; when a passenger compartment needs to be heated, cooling liquid is heated through heating of the water heater or heat absorption of the water condenser from a refrigerant pipeline of an air conditioning system, and when the cooling liquid passes through the warm air core body, the air blower blows heat into the passenger compartment. A power battery system cooling loop, an electric drive system cooling loop and a passenger compartment heating loop are designed in a coupling mode, and heat management energy consumption is reduced on the premise that the temperature requirements of all systems of the whole vehicle are met according to different whole vehicle using working conditions.
