摘要

Provided is a battery pack, and more particularly, a battery pack capable of preventing degradation of performance at a low temperature by allowing a portion of air exhausted through an exhaust port to be introduced into an inhalation port to optimize a temperature of external air introduced into a cell module.

主权项

1. A battery pack, comprising:
a case having an inhalation port and an exhaust port formed therein, cooling air being inhaled or exhausted into or from the inhalation port or the exhaust port; a cell module included in the case and configured by arranging a plurality of battery cells in parallel to each other while having a predetermined distance; an inhalation duct having one side connected to the inhalation port and the other side opened toward the cell module side; an exhaust duct having one side connected to the exhaust port and the other side opened toward the cell module side; and a circulation flow path connecting the inhalation duct and the exhaust duct to each other.
