    摘要: Disclosed is a battery pack configured to effectively suppress a fire even when high-temperature gas or sparks are generated in some battery modules. The battery pack includes at least one battery module having at least one secondary battery and configured to store and release an energy; a duct provided to at least one side of the battery module and configured to have a discharge hole so that, when a gas is generated from the battery module, the generated gas flows toward the discharge hole; and an opening/closing member located at the discharge hole of the duct and configured to open the discharge hole when an internal pressure of the duct is in a predetermined level or above and to close the discharge hole when the internal pressure of the duct is in the predetermined level or below.
