The invention relates to a hybrid electric vehicle thermal management system and a vehicle, the hybrid electric vehicle thermal management system comprises an air-conditioning system and a battery heat cycle, the air-conditioning system comprises an external heat exchanger and an internal heat exchanger used for refrigerating or heating the interior of the vehicle, and a compressor, the external heat exchanger, an expansion valve and the internal heat exchanger in the air-conditioning system form an internal refrigerating loop; the air-conditioning system exchanges heat with battery heat circulation through the first heat exchanger, the first heat exchanger forms an evaporator of air-conditioning heat pump circulation at the air-conditioning heat exchange end in the air-conditioning system, and the compressor, the in-vehicle heat exchanger, the expansion valve and the air-conditioning heat exchange end in the air-conditioning system form an in-vehicle heating loop. The heat pump air conditioner solves the problem that a heat radiator of the heat pump air conditioner is too large in size. Through specific arrangement of an air-conditioning circulation pipeline, air-conditioning refrigeration of the passenger compartment can be achieved, and the battery is cooled through a heat exchanger connected with battery heat circulation by means of air-conditioning refrigeration.
