The invention discloses a whole vehicle thermal management system for a pure electric commercial vehicle. The whole vehicle thermal management system is provided with a passenger compartment refrigeration cycle subsystem, a passenger compartment warm air cycle subsystem, a battery thermal management subsystem and a motor assembly thermal management subsystem, the passenger compartment refrigeration cycle subsystem comprises a compressor, a water-cooling condenser, an evaporator, a heat regenerator, a first cooler and a second cooler which are connected through a passenger compartment refrigerant circulation pipeline, and refrigerant transmission pipelines and water medium transmission pipelines which are independent of one another are arranged in the water-cooling condenser, the first cooler and the second cooler. Refrigerant transmission pipelines of the water cooling condenser, the first cooler and the second cooler are connected in a passenger compartment refrigerant circulation pipeline, a water medium transmission pipeline of the water cooling condenser and a water medium transmission pipeline of the first cooler are connected with a motor assembly heat management subsystem, and a water medium transmission pipeline of the second cooler is connected with a battery heat management subsystem. And the heat regenerator is arranged among the water-cooling condenser, the evaporator and the first cooler. The purpose of improving the economical efficiency, the dynamic property and the comfort of the vehicle is achieved.
