1. A controller-implemented charger cooling air source selection method, a controller causing steps comprising:
- cooling a vehicle battery charger by opening an outside air vent door of the vehicle and drawing outside air through the outside air vent door while maintaining a recirculation door in a closed configuration, the outside air vent door in a rear portion of the vehicle, the recirculation door in a front portion of the vehicle;
determining whether the outside air vent door will close in response to an attempt to close the outside air vent door caused by the controller; and
if the outside air vent door will not close, establishing and maintaining positive air pressure in a cabin of the vehicle by ensuring an open configuration of the recirculation door in the vehicle, the recirculation door configured to close the cabin to outside air through the recirculation door in the closed configuration and open the cabin to outside air through the recirculation door in the open configuration.

9. A controller-implemented charger cooling air source selection method, a controller causing steps 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 while maintaining a recirculation door in a closed configuration, the outside air vent door in a rear portion of the vehicle, the recirculation door in a front portion of the vehicle; determining whether the outside air vent door will close in response to an attempt to close the outside air vent door caused by the controller; and if the outside air vent door will not close, establishing and maintaining positive air pressure in the cabin of the vehicle by ensuring an open configuration of the recirculation door in the vehicle, the recirculation door configured to close the cabin to outside air through the recirculation door in the closed configuration and open the cabin to outside air through the recirculation door in the open configuration. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A controller-implemented charger cooling air source selection method, a controller causing steps comprising:
-
charging a vehicle battery of a vehicle by operation of a vehicle battery charger; determining whether the vehicle battery charger requires cooling and a temperature of a cabin of the vehicle exceeds a predetermined set temperature; determining if the vehicle battery charger requires cooling and the temperature of the cabin of the vehicle exceeds the predetermined set temperature; if the vehicle battery charger requires cooling, cooling the vehicle battery charger by opening an outside air vent door and operating a vehicle climate control fan in a vehicle to draw outside air from outside the vehicle through the outside air vent door into a cabin of the vehicle by operating an outside air fan, the outside air vent door being opened while maintaining a recirculation door in a closed configuration, the outside air vent door in a rear portion of the vehicle, the recirculation door in a front portion of the vehicle; determining whether the outside air vent door will close in response to an attempt to close the outside air vent door caused by the controller; and if the outside air vent door will not close, establishing and maintaining positive air pressure in the cabin of the vehicle by ensuring an open configuration of the recirculation door in the vehicle, the recirculation door configured to close the cabin to outside air through the recirculation door in the closed configuration and open the cabin to outside air through the recirculation door in the open configuration. - View Dependent Claims (18, 19, 20)
