Abstract
An environmental control system for a battery in a vehicle includes an air intake for receiving ambient air from outside the vehicle. A duct system provides communication between the air intake and the battery. The duct system includes a movable door which can facilitate or inhibit movement of air between the air intake and the battery. An air outlet facilitates air flow from the duct system to the ambient environment outside the vehicle. A fan cooperates with the duct system for moving the air through a heat exchanger in the duct system and across the battery. A control system controls operation of the fan and the movable door, and is configured to determine whether the battery environment requires fresh air or recirculated air.
