The invention belongs to the field of electric vehicle thermal management systems, and discloses an electric vehicle thermal management system and method based on a transcritical carbon dioxide heat pump air conditioner. The system comprises a CO2 heat pump system module, a cab HVAC module, a cooling liquid treatment module and a waste heat dissipation module. A reasonable comprehensive control scheme is adopted, and ten control modes including a battery fast charging mode, a passenger cabin single-cooling mode, a passenger cabin single-heating mode, a cab single-cooling mode, a cab single-heating mode, a whole vehicle heating mode, a whole vehicle refrigeration mode, a waste heat recovery mode, a battery thermal management mode and a demisting mode are included. Compared with a traditional electric vehicle air conditioner, the natural working medium CO2 is adopted as a refrigerant, energy of the whole coach is comprehensively integrated and utilized, the battery burden is greatly reduced, and the thermal comfort and the endurance mileage of the electric vehicle are improved.
