Abstract
A power supply device for a vehicle, for driving a motor which is mounted on a vehicle and makes the vehicle travel. The power supply device for a vehicle includes: a battery unit having a plurality of secondary batteries; a battery temperature sensor for detecting the temperature of a secondary battery; a heat insulating mechanism for controlling the temperature of the secondary battery; an outside air temperature sensor for detecting the temperature of air outside of the vehicle; an air intake port for taking the outside air to the battery unit in the vehicle; an intake valve for opening/closing the intake port; and a temperature controller for controlling the opening/closing of the intake valve on the basis of the temperature difference between the outside air temperature detected by the outside air temperature sensor and the battery temperature detected by the battery temperature sensor.
