The invention discloses a whole electric vehicle thermal management system based on R290 and a control method of the whole electric vehicle thermal management system. The system comprises a heat pump system, a first heat transfer loop, a second heat transfer loop, a battery loop and an electric drive cooling system. A refrigerant of the heat pump system is R290, and the whole heat pump circulation loop is arranged in a front cabin of the vehicle; the first heat transfer loop can obtain heat from the heat pump system through the first heat exchanger and transfer the heat to the first radiator or the warm air core body; the second heat transfer loop can obtain cold energy from the heat pump system through the second heat exchanger and transfer the cold energy to the second radiator or the cold air core body; the battery loop is connected with the first heat transfer loop and the second heat transfer loop through pipelines, so that the temperature of the battery pack can be adjusted; the electric drive cooling system is connected with the second heat transfer loop through a pipeline, and heat of the electric drive system can be dissipated through the second radiator or provided for the heat pump system through the second heat exchanger.
