Abstract

A vehicle cabin venting method includes cooling a vehicle battery charger by drawing outside air through a vehicle outside air vent door; and operating a hybrid vehicle battery system to establish and maintain flow of fresh air in a cabin of the vehicle by ensuring an open position of a blend door in the vehicle if the outside air vent door will not close. A vehicle cabin venting system is also disclosed.

Claims

1. A battery charger cooling method, comprising:

cooling a vehicle battery charger by drawing outside air through a vehicle outside air vent door; and

operating a hybrid vehicle battery system to establish and maintain flow of fresh air in a cabin of the vehicle by ensuring an open position of a blend door in the vehicle if the outside air vent door will not close.

2. The method of claim 1 further comprising drawing outside air through the vehicle outside air vent door by operating the hybrid vehicle battery system to operate an outside air fan.

3. The method of claim 1 wherein operating the hybrid vehicle battery system to establish and maintain flow of fresh air in a cabin of the vehicle by ensuring an open position of a blend door in the vehicle comprises operating the hybrid vehicle battery system to operate a vehicle climate control fan.

4. The method of claim 1 wherein cooling a vehicle battery charger comprises opening the vehicle outside air vent door in the vehicle if a temperature of the cabin of the vehicle exceeds a predetermined set temperature.

5. The method of claim 1 wherein drawing outside air through the outside air vent door comprises drawing outside air through the outside vent door through a fan outlet duct disposed in thermally conductive contact with a vehicle battery charger.

6. The method of claim 1 wherein ensuring an open position of a blend door in the vehicle comprises operating a battery energy control module to open the blend door from a closed position.

7. The method of claim 1 wherein ensuring an open position of a blend door in the vehicle comprises operating a battery energy control module to maintain the blend door in an open position.

8. The method of claim 1 further comprising removing inside air from the cabin of the vehicle.

9. A battery charger cooling method, comprising:

charging a vehicle battery of a vehicle by operation of a vehicle battery charger;

cooling the vehicle battery charger by opening an outside air vent door in a vehicle and drawing outside air from outside the vehicle, through the outside air vent door into a cabin of the vehicle;

operating a battery energy control module to determine whether the outside air vent door is closed; and

operating a hybrid vehicle battery system to establish and maintain flow of fresh air in a cabin of the vehicle by ensuring an open position of a blend door in the vehicle if the outside air vent door will not close.

10. The method of claim 9 further comprising further comprising drawing outside air through the outside air vent door by operating the hybrid vehicle battery system to operate an outside air fan.

11. The method of claim 9 wherein operating a hybrid vehicle battery system to establish and maintain flow of fresh air in a cabin of the vehicle by ensuring an open position of a blend door in the vehicle comprises operating the hybrid vehicle battery system to operate a vehicle climate control fan.

12. The method of claim 9 wherein cooling a vehicle battery charger comprises opening the outside air vent door in the vehicle if a temperature of the cabin of the vehicle exceeds a predetermined set temperature.

13. The method of claim 9 wherein drawing outside air through the outside air vent door comprises drawing outside air through the outside vent door through a fan outlet duct disposed in thermally conductive contact with the vehicle battery charger.

14. The method of claim 9 wherein ensuring an open position of a blend door in the vehicle comprises operating the battery energy control module to open the blend door from a closed position.

15. The method of claim 9 wherein ensuring an open position of a blend door in the vehicle comprises operating the battery energy control module to maintain the blend door in an open position.

16. The method of claim 9 further comprising removing inside air from the cabin of the vehicle.

17. A vehicle cabin venting system, comprising:

a controller;

an outside air vent door interfacing with the controller, controller detects when the vehicle outside air vent door will not close; and

a blend door interfacing with the controller, the controller maintains the blend door in an open position when the vehicle outside air vent door will not close.

18. The system of claim 17 wherein the controller comprises a hybrid vehicle battery system, the outside air vent door interfacing with the hybrid vehicle battery system.

19. The system of claim 18 further comprising a climate control module interfacing with the hybrid vehicle battery system, the climate control module interfacing with the blend door.

20. The system of claim 19 further comprising a climate control fan interfacing with the blend door and the climate control module.
