Battery temperature control device for controlling the temperature of battery installed in vehicle
First Claim
1. A battery temperature control device for controlling the temperature of a battery installed in a vehicle, the battery temperature control device comprising:
- a rear air-conditioning unit, which is arranged at a rear side of the vehicle and includes an air temperature adjusting means for adjusting the temperature of air discharged from the rear air-conditioning unit into a passenger compartment of the vehicle; and
an air passage, which conducts air from a downstream side of the air temperature adjusting means to the battery, so that the air that has passed through the air temperature adjusting means is supplied to the battery to control the temperature of the battery.

Abstract
Air for cooling a battery is supplied to the battery from a rear unit through a duct. In this way, the temperature of the air blown to the battery can be reduced in comparison to a case where inside air is taken from a passenger compartment and is supplied to the battery for cooling the battery. Thus, the battery can be sufficiently cooled, so that the amount of air flow supplied to the battery needs not be increased to achieve enough cooling capacity for cooling the battery. As a result, air blowing noises can be reduced, and a reduction in a service life of a second blower can be restrained. Furthermore, since sufficient cooling capacity is achieved, there is no need to increase a radiating surface area of the battery. Thus, an increase in a size of the battery and an increase in a manufacturing cost can be restrained.
