1. A battery module comprising:
a battery stack including a plurality of batteries that are stacked, the plurality of batteries including valves through which a gas is blown off, the valves being disposed on a surface of the battery stack;
a duct plate configured to cover the surface of the battery stack, the duct plate including a gas discharge duct that extends in a stacking direction of the batteries, is connected to the valves of the batteries, and temporarily stores the gas blown off through the valves;
a cover plate placed on the duct plate; and
a flow path defined by the duct plate and the cover plate, the flow path extending from the gas discharge duct in a first direction that intersects with the stacking direction of the batteries and allowing leaking of the gas in the gas discharge duct to an outside of the battery module,
wherein the cover plate includes an opening through which a midst part of the flow path is communicable with the outside of the battery module,
the flow path has a first end portion thereof communicating with the gas discharge duct, and a second end portion thereof defining a flow path outlet,
the opening is interposed between the first end portion and the second end portion of the flow path in a horizontal direction different than the stacking direction of the batteries, such that in at least one cross section perpendicular to the stacking direction of the batteries, the flow path is continuous from the gas discharge duct, past the opening, and then to the flow path outlet in a single direction, and
the opening is configured to direct the gas therethrough in an upward direction to the outside of the battery module.
