Abstract
A battery pack configured to suppress a fire by spraying a coolant from above or submerging at least a portion of the battery pack in the coolant in response to a fire occurring in the battery pack. In response to a fire occurring in a battery pack, a coolant may be sprayed from above to serve as a sprinkler. The fire may be extinguished and heat propagation may be suppressed by submerging at least a portion of the battery pack in the coolant. Since the fire may be extinguished immediately and the heat propagation may be prevented even when a battery cell reaches thermal runaway, safety of the battery pack may be improved.
Claims15
A battery pack comprising:
- a plurality of battery cells comprising a plurality of vent holes;
- an upper cooling unit on the battery cells, the upper cooling unit comprising a coolant and a plurality of spray holes;
- and
- a lower cooling unit in contact with a lower portion of the plurality of battery cells, the lower cooling unit comprising the coolant,
- wherein the plurality of spray holes in the upper cooling unit correspond to the plurality of vent holes of the plurality of battery cells, and
- wherein the upper cooling unit is configured to spray the coolant through a spray hole of the plurality of spray holes in response to a fire occurring in a corresponding battery cell of the plurality of battery cells.
A battery pack comprising:
- a plurality of battery cells;
- a case accommodating the plurality of battery cells;
- a coolant inlet in one side surface of the case;
- and
- a coolant outlet in another side surface of the case,
- wherein the battery pack is configured to introduce a coolant into the case through the coolant inlet and to submerge at least portions of the battery cells in the coolant in response to a fire occurring in a battery cell of the plurality of battery cells.
