Abstract

A vehicle traction battery cooling system is provided. The battery cooling system includes a blend door movable between at least an open and a closed position to select the location of incoming air for cooling a plurality of battery cells. A controller is configured to command the door to the open position in response to detecting gases vented by the battery cells.

First claim

What is claimed is:

1. A method for cooling a traction battery in a vehicle, the method comprising:
receiving, by a controller, a signal indicative of a presence of gases vented by the battery;
commanding, by the controller, a cabin climate control system parameter to change in response to the signal.

2. The method of claim 1 wherein commanding the cabin climate control system parameter to change further comprises commanding, by the controller, a blend door to move to an open position to direct air from outside the vehicle into a battery cooling system.

3. The method of claim 2 wherein commanding the cabin climate control system parameter to change further comprises commanding, by the controller, a fan located downstream of the blend door to increase speed to direct air from outside the vehicle into the battery cooling system.

4. The method of claim 1 wherein commanding the cabin climate control system parameter to change comprises commanding, by the controller, a fan in fluid communication with the battery to increase speed, wherein the fan directs air from a battery chamber to outside the vehicle.

5. The method of claim 1 , in response to detecting the presence of gases vented by the battery, the method further comprising:
commanding, by the controller a blend door to move to an open position to direct air from outside the vehicle into a climate control duct system connected to a battery cooling system;
commanding, by the controller, a climate control fan located downstream of the blend door to increase speed to direct air from outside the vehicle into the battery cooling system; and
commanding, by the controller, a battery fan located downstream of the battery to increase speed, wherein the fan blows air from a battery chamber outside the vehicle.

6. The method of claim 2 wherein further comprising receiving, by the controller, the signal of a presence of gases vented by the battery from a sensor disposed in a battery chamber.
