The invention relates to the technical field of air conditioners, and discloses an electric vehicle heat pump air conditioning system and an electric vehicle. The heat pump air conditioning system comprises an air supplementing branch, an air supply expansion valve and an intermediate heat exchanger; a compression unit comprises an air supplementing compressor, the first end of the air supplementing branch is connected to an air supplementing opening of the air supplementing compressor, and the second end of the air supplementing branch is connected to a pipeline between an in-vehicle heat exchange unit and a main path expansion valve; a low-temperature side of the intermediate heat exchanger and the air supply expansion valve are connected to the air supplementing branch in series, and ahigh-temperature side of the intermediate heat exchanger is connected to a pipeline between the in-vehicle heat exchange unit and the main expansion valve in series. And the air supplementing branch also flows through at least one of a motor, a battery and an electric controller of the vehicle. According to the heat pump air conditioning system of the electric vehicle and the electric vehicle provided by the invention, recovery of at least one part of heat of the vehicle motor, the battery and the electric controller is realized through the air supplementing branch, and extra heat absorption income is obtained; therefore, the heating capacity is effectively increased, and the heating efficiency is improved.
