Battery pack and automobile

The invention discloses a battery pack and an automobile, the battery pack comprises a shell, a condensation part and a liquid collector, the shell is provided with a mounting cavity, a heat exchange pipeline is arranged in the mounting cavity, and the heat exchange pipeline is used for communicating with a cooling system; the condensation part is arranged in the mounting cavity and is in heat conduction connection with the outer side wall of the heat exchange pipeline so as to exchange heat with a low-temperature refrigerant in the heat exchange pipeline and induce water vapor in the mounting cavity to be condensed; the liquid collector is arranged below the condensation piece and provided with a containing cavity facing an opening of the condensation piece. According to the technical scheme, after the low-temperature refrigerant of the cooling system enters the heat exchange pipeline, the low temperature is transmitted to the condensation part, so that the temperature of the condensation part is reduced, th
