A cooling system for a battery in a vehicle does not use air from the vehicle passenger compartment, but rather, takes in ambient air from outside the vehicle. When the temperature of the ambient air outside the vehicle is low enough, the air is moved through a duct system by a pair of fans and blown across a battery assembly. When the temperature of the ambient air outside the vehicle is too warm to cool the battery directly, it is first passed through an evaporator coil where it exchanges heat with a refrigerant, prior to being blown across the battery assembly. The cooling air may be recirculated across the battery assembly, or exhausted from the vehicle through an air extractor.

Cooling system for a vehicle battery

The present invention provides a method for masking noise in a motor vehicle that has a component that produces noise when operated. The method of the invention comprises monitoring the speed of the vehicle, and increasing the movement of the moveable part when the vehicle is at a predetermined speed. It is well known that vehicles naturally produce more noise as the speed of the vehicle is increased. The invention also provides a noise masking system that exploits the method of the invention.
