Abstract
In a battery pack, a plurality of batter modules provided with safety vents for discharging gas are arranged in parallel. A gas discharging device is provided in which discharge outlets of the safety vents of the respective battery modules are connected to at least one discharge gas tube installed in the alignment direction of the battery modules and connected to an external discharging section. The battery modules are connected in a manner that changes in the intervals between the discharge outlets of respective safety vents, due to expansion of the battery modules, are absorbed by expansion or displacement of theat least one discharge gas tube.
