Kind Code:
A1
Abstract:
Provided is a battery module that is capable of discharging, outside a casing, high-temperature gas that is discharged by a malfunctioning battery, without affecting properly functioning batteries, while alleviating, to the extent possible, increases in volume caused by the discharge chamber. The battery module according to the present invention comprises: a casing, further comprising an aperture part and a discharge opening that discharges gas that is generated internally; a plurality of batteries, further comprising terminal plates whereon opening parts for discharging gas that is generated internally are disposed, and which are positioned in parallel within the casing in a state wherein the terminal plates are facing the aperture part; and a lid body that is attached to the casing so as to cover the aperture part, further comprising a flat plate part and a plurality of projections that protrude from the plane that includes the flat plate part toward the interior of the casing, and that are connected to the terminal plates of the batteries. A flow path from the opening parts on the batteries to the discharge port of the casing is formed by a space that is formed between the projections of the lid body.
