Battery cooling system for vehicle
First Claim
1. A vehicle-use battery cooling system for cooling a battery mounted in a vehicle whose vehicle compartment is air conditioned by an air conditioner, so as to maintain the battery in a predetermined temperature range, comprising:
- a battery chamber for accommodating the battery;
cooling means having a cooling fan and adapted to cool the battery by supplying air in the vehicle compartment to an interior of said battery chamber by said cooling fan;

exhausting means for exhausting the air used in cooling the battery to outside the vehicle;
changeover means for effecting a changeover between said cooling-air circulating means and said exhausting means;
temperature detecting means for detecting at least one of a temperature of the interior of said battery chamber and a temperature of said battery; and
changeover controlling means for selecting said exhausting means by said changeover means when the temperature detected by said temperature detecting means has become greater than or equal to a predetermined value.
