Abstract
A battery module includes: a plurality of aligned battery cells; a cooling gas inlet for supplying cooling gas to the battery cells; and a cooling gas valve in the cooling gas inlet. Each of the battery cells includes a battery case configured to bulge in response to a second pressure in the battery case, an electrode assembly in the battery case, a cap assembly on the battery case, and a gas exhaust vent configured to rupture in response to a first pressure in the battery case that is higher than the second pressure. The cooling gas inlet is defined by first and second side walls. The first side wall is configured to deform in response to a bulged battery case, and the cooling gas valve is configured to change from an open position into a closed position due to the deformation of the first side wall.

A battery module comprising:
- a plurality of battery cells aligned along a first direction, each of the battery cells comprising a battery case, an electrode assembly accommodated in the battery case, a cap assembly on the battery case, and a gas exhaust vent configured to rupture in response to a first pressure in the battery case, the battery case being configured to bulge in response to a second pressure in the battery case, the second pressure being lower than the first pressure;
- a cooling gas inlet for supplying cooling gas to the battery cells, the cooling gas inlet being defined by a first side wall and a second side wall, the first side wall being configured to deform in response to a bulged battery case;
- and
- a cooling gas valve in the cooling gas inlet, the cooling gas valve being configured to change from an open position into a closed position due to the deformation of the first side wall.
