Battery cooling structure for vehicle

A battery cooling structure for a vehicle comprising:

• a battery storage space that is defined underneath a luggage compartment provided behind a rear seat and covered by a rear floor;
• a battery module that is stored in the battery storage space;
• and
• a battery cooling unit that cools the battery module using air that is taken in from a passenger compartment and discharges air used to cool the battery module into the battery storage space,
• wherein the battery cooling structure further comprises:
• a passenger compartment-bound exhaust air flow path that returns an exhaust air discharged into the battery storage space to the passenger compartment;
• and
• a luggage compartment-bound exhaust air flow path that includes a space defined between a body of the vehicle and a side trim and that discharges the exhaust air into the luggage compartment,
• wherein an inlet port that introduces air to cool the battery module from the passenger compartment is disposed at one transverse end portion below a front end portion of the rear seat, and
• wherein an outlet port of the passenger compartment-bound exhaust air flow path is disposed at an other transverse end portion below the front end portion of the rear seat.
