  • Patent number: 7025159
    Abstract: 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.

  • Publication number: 20050059338
    Abstract: An air intake for a vehicle that facilitates air transfer from an ambient environment outside the vehicle to a vehicle space is provided. The air intake inhibits liquid transfer from the ambient environment to the vehicle space. The air intake includes a housing having an inlet for receiving air from the ambient environment, and an outlet in communication with the inlet. The outlet is disposed in an upper portion of the housing. A blocking member is disposed within the housing adjacent the inlet for preventing upward fluid flow from the inlet directly to the outlet, thereby inhibiting liquid flow through the outlet and into the vehicle space. A portion of the air intake housing is configured for attachment to a vehicle window, and the inlet is configured to be disposed along one edge of the window.
