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.

1. A method for controlling a vehicle battery environment, comprising: exchanging air between the battery environment and an ambient environment outside the vehicle when a battery state of charge is greater than a first predetermined charge level; andinhibiting air exchange between the battery environment and the ambient environment outside the vehicle based on at least one battery-related condition and a transmission of the vehicle is in a park or neutral gear. 2. The method of claim 1, further comprising exchanging air between the battery environment and the ambient environment outside of the vehicle when the battery is in a reconditioning mode. 3. The method of claim 1, further comprising inhibiting air exchange between the battery environment and the ambient environment outside the vehicle based on the at least one battery-related condition, and a battery air conditioning system is operating to cool the battery, and the transmission is in a forward or reverse gear. 4. The method of claim 1, further comprising exchanging air between the battery environment and the ambient environment outside the vehicle when a temperature of the battery is greater than a first predetermined temperature, a temperature difference between the battery temperature and the temperature of the ambient environment outside the vehicle is greater than a second predetermined temperature, the transmission is in a forward or reverse gear, and a battery air conditioning system is not operating to cool the battery. 5. The system of claim 1, wherein the at least one battery condition includes at least one of: a reconditioning mode of the battery, a voltage deviation in the battery, an unexpected current sensor reading, or an unexpected sensor reading from an individual cell of the battery. 6. A method for controlling a vehicle battery environment, comprising: exchanging air between the battery environment and an ambient environment outside the vehicle based on at least one battery-related condition independent of temperature; andexchanging air between the battery environment and the ambient environment outside the vehicle for a predetermined time based on the at least one battery-related condition and the vehicle is in a key-off mode. 7. The method of claim 6, wherein the at least one battery-related condition includes the battery being in a reconditioning mode. 8. The method of claim 6, wherein the at least one battery-related condition includes a battery state of charge being greater than a first predetermined charge level. 9. The method of claim 6, further comprising inhibiting air exchange between the battery environment and the ambient environment outside the vehicle based on the at least one battery-related condition, and a battery air conditioning system is operating to cool the battery, and a transmission of the vehicle is in a forward or reverse gear. 10. The method of claim 6, further comprising exchanging air between the battery environment and the ambient environment outside the vehicle when a temperature of the battery is greater than a first predetermined temperature, a temperature difference between the battery temperature and the temperature of the ambient environment outside the vehicle is greater than a second predetermined temperature, a transmission of the vehicle is in a forward or reverse gear, and a battery air conditioning system is not operating to cool the battery. 11. An environmental control system for a vehicle battery environment, comprising: a controller configured to effect an air exchange between the battery environment and an ambient environment outside the vehicle when the battery is in a reconditioning mode, and to inhibit air exchange between the battery environment and the ambient environment outside the vehicle based on at least one battery-related condition and a transmission of the vehicle is in a park or neutral gear. 12. The system of claim 11, further comprising exchanging air between the battery environment and the ambient environment outside of the vehicle when a battery state of charge is greater than a first predetermined charge level. 13. The system of claim 11, wherein the controller is further configured to inhibit air exchange between the battery environment and the ambient environment outside the vehicle, based on the at least one battery-related condition, and a battery air conditioning system is operating to cool the battery, and the transmission is in a forward or reverse gear. 14. The system of claim 11, wherein the controller is further configured to effect an air exchange between the battery environment and the ambient environment outside the vehicle when a temperature of the battery is greater than a first predetermined temperature, a temperature difference between the battery temperature and the temperature of the ambient environment outside the vehicle is greater than a second predetermined temperature, the transmission is in a forward or reverse gear, and a battery air conditioning system is not operating to cool the battery.
