The invention relates to an automobile power battery direct cooling system and an automobile. The system comprises a compressor, a condensation mechanism, a first expansion valve, a second expansion valve, a battery direct cooling heat exchanger, an in-automobile evaporator and an intermediate heat exchanger. The compressor, the condensation mechanism, the first expansion valve and the in-vehicleevaporator are sequentially connected through pipelines to form a first cooling pipeline loop. The compressor, the condensation mechanism, a second expansion valve and a battery direct-cooling heat exchanger are sequentially connected through pipelines to form a second cooling pipeline loop; wherein a first heat exchange pipeline and a second heat exchange pipeline are arranged in the intermediateheat exchanger, and the first heat exchange pipeline is a part of a pipeline for connecting the compressor and the battery direct-cooling heat exchanger; and a second heat exchange pipeline is a partof a pipeline for connecting the compressor with the battery direct-cooling heat exchanger. The temperature uniformity of the battery direct-cooling heat exchanger can be improved, the battery energyefficiency can be improved, the COP value of an automobile power battery cooling system is improved, and the energy is saved.
