  • Publication number: 20140308559
    Abstract: According to the present invention, a battery-cooling system for an electric vehicle is configured such that the cool air cooled by an air-conditioning device is directly supplied to a battery without passing through the interior of a vehicle, thus enabling the interior of the vehicle and the battery to be cooled independently from each other, thereby not only preventing noise or foreign substances from entering the battery from the interior of the vehicle, but also controlling a vehicle interior cooling operation and a battery cooling operation independently from each other. Further, a battery-cooling system for an electric vehicle according to the present invention is configured such that a suction fan is arranged at a discharge duct for discharging air from the interior of a battery, thus enabling air in the interior of the battery to be suctioned and discharged by the suction fan.
