Abstract: The present invention provides an outlet duct for discharging air to the outside during air cooling in a battery system for a hybrid electric vehicle. The outlet duct of a battery system for a hybrid electric vehicle in accordance with the present invention has a new structure in which the outlet duct, through which air is discharged after air-cooling of the battery system (or high voltage parts), does not extend to an extractor grill; instead, an inlet hole is formed at a front end of a rear filler assembly and an outlet hole is formed at a rear end thereof. With the structure, cooling performance can be improved. Moreover, it is possible to prevent water or dust from being introduced from the bottom of the vehicle due to the shape of the side member. Furthermore, it is possible to simplify the shape of the outlet duct, thereby improving productivity. In addition, it is possible to reduce the pressure resistance against the air flow in advance, thereby improving cooling performance.
