Abstract

The present disclosure relates to a battery module and an energy storage system including the same in which a fire extinguishing conduit is positioned to be spaced apart from the center of a vent in a horizontal direction, thereby preventing the conduit from being lost by gas through the vent due to an event. As an example, the present disclosure provides a battery module and an energy storage system, wherein the battery module includes a module case which has an accommodation space therein and in which a plurality of battery cells are accommodated, a module pipe which is positioned above the module case and through which a fire extinguishing agent is movable, and a pipe guide rail which includes an accommodation portion in which the module pipe is accommodated and which is positioned on the module case, wherein each of the plurality of battery cells includes a vent, the vents of the plurality of battery cells are collinearly positioned in a longitudinal direction, and the module pipe and the accommodation portion are positioned to not overlap central areas of the vents in a horizontal direction.
