The invention discloses an electric automobile heat pump system and an electric automobile. Comprising a motor device, a radiator, a compressor, a gas-liquid separator, an in-vehicle condenser, an in-vehicle evaporator, a battery pack, a first expansion valve, a second expansion valve, a first heat exchanger used for exchanging heat with the external environment, a second heat exchanger used for exchanging heat with the battery pack, and a third heat exchanger used for waste heat exchange and utilization of the motor device and/or the battery pack. According to the electric vehicle heat pump system and the electric vehicle, the first heat exchanger, the gas-liquid separator, the compressor and the in-vehicle condenser can form a conventional air source heat pump to absorb environment heat for heating. The third heat exchanger, the gas-liquid separator, the compressor and the in-car condenser can form a water source heat pump, heating is carried out by recycling waste heat of the motor device and the battery pack, and the heating requirement of a passenger compartment is met by fully exerting the advantages of the air source heat pump and the water source heat pump of the electric car.
