The invention belongs to the technical field of automobile thermal management, and particularly relates to a new energy automobile thermal management system and an automobile. The new energy automobile thermal management system comprises a heat pump air conditioner refrigerant subsystem and a cooling liquid loop subsystem; the heat pump air conditioner refrigerant subsystem comprises a compressor, a water cooling condenser, a first three-way valve, a first electronic expansion valve, an evaporator, a second electronic expansion valve, a second three-way valve, a one-way valve, a stop valve, an evaporative condenser and a third electronic expansion valve. And the cooling liquid loop subsystem comprises a water-cooling condenser loop formed by sequentially communicating a second electronic water pump, a water-cooling condenser, a second three-way water valve and a warm air heater. The problems that in the prior art, a new energy automobile needs insufficient refrigerating capacity when battery fast charging cooling and passenger compartment refrigerating are conducted at the same time at the high temperature, and the heating energy efficiency ratio of a heat pump is low at the low temperature are effectively solved, and the energy efficiency ratio and the endurance mileage of the automobile are effectively increased.
