The invention discloses a traction battery air thermal management control system. The vehicle traction battery system may include a battery pack, a fan configured to direct air flow to the pack, and a controller. The controller may be programmed to, in response to a predicted pack temperature being greater than a first predefined temperature, direct the fan to operate at a predefined generally constant speed that does not change with vehivle speed or engine on/off state until the predicted battery pack temperature falls below a second predefined temperature. A method is also provided for cooling the vehicle traction battery system based on a predicted battery pack temperature and a heat generation rate.
