A battery module includes at least one battery cell, a module case configured to accommodate the at least one battery cell, a fire extinguisher disposed at least partially inside the module case and connected to a fire extinguishing tank containing a fire extinguishing agent to inject the fire extinguishing agent directly into the module case when a thermal runaway or fire occurs in the at least one battery cell and an insulation cover configured to cover the fire extinguisher at least partially and disposed at least partially inside the module case.

Battery module comprising a fire extinguisher, battery rack comprising same, and power storage device

A battery module includes at least one battery cell; and a module case configured to accommodate the at least one battery cell, wherein a fire extinguishing agent supply channel connected to a fire extinguishing tank containing a fire extinguishing agent to directly inject the fire extinguishing agent into the module case when a thermal runaway or fire occurs at the at least one battery cell is provided to an inside of at least one side of the module case.

Battery module, battery rack comprising same battery module, and power storage device comprising same battery rack

A battery module includes a cell stack formed by stacking a plurality of battery cells including a receiving portion in which an electrode assembly is accommodated, a first edge portion and a second edge portion along the longitudinal direction around the receiving portion, and a third edge portion and a fourth edge portion along the width direction, in the vertical direction with the receiving portions facing each other, the battery cell includes a resealing portion at the first edge portion, and includes a sealing portion or an unsealed portion at the second edge portion, and the first edge portion and the second edge portion are alternately positioned along the vertical direction on both sides of the cell stack.

Battery module, and battery pack and energy storage system including the same

A battery module includes a cell stack including a plurality of battery cells stacked in a direction, a module housing having an internal space in which the cell stack is received and an air inlet and an air outlet through which air enters and exits, a valve installation hole formed through a side wall of the module housing, a feed valve nozzle installed at the valve installation hole facing the internal space of the module housing, and a water expandable member provided in the module housing.
