The invention discloses an automotive thermal management system and a control method for realizing delayed frosting and rapid defrosting, and belongs to the technical field of thermal management of electric automobiles. The thermal management system for the vehicle comprises the CO2 heat pump air conditioning system and the cooling liquid system, heat is provided for the CO2 heat pump air conditioning system through the heat storage water tank and the battery motor heat exchange module of the cooling liquid system, and the functions of frosting delaying and rapid defrosting are achieved by adjusting valve control between the two systems. The control method provided by the invention comprises a delayed frosting control method and a rapid defrosting control method, the temperatures of a plurality of key parts are monitored, and the heat of the heat storage water tank and the battery motor heat exchange module is reasonably utilized; the problems that an external heat exchanger of an electric automobile is frequently frosted and slowly defrosted under the low-temperature and high-humidity working conditions, and the comfort of a passenger compartment is poor in the defrosting process are solved. And the frosting time can be delayed, quick defrosting is achieved, and complementation and efficient utilization of energy of the whole vehicle are achieved.
