Abstract
A battery structure includes a plurality of battery packs, and a fluid storage part disposed at one side of the plurality of battery packs and configured to store an electrically insulative fire extinguishing fluid. Each of the plurality of battery packs includes a plurality of battery cells including electrodes and separators, a casing part defining an internal space configured to accommodate the battery cells, and a piping line connected to one end to the casing part and at another end to the fluid storage part, the piping line having a flow path configured to deliver the fire extinguishing fluid to the casing part.
Claims17
A battery structure comprising:
- a plurality of battery packs;
- and
- a fluid storage part disposed at one side of the plurality of battery packs and configured to store an electrically insulative fire extinguishing fluid,
- wherein each of the plurality of battery packs comprises:
- a plurality of battery cells comprising electrodes and separators;
- a casing part defining an internal space configured to accommodate the battery cells;
- and
- a piping line connected at one end to the casing part and at another end to the fluid storage part, the piping line having a flow path configured to deliver the fire extinguishing fluid to the casing part.
A method for extinguishing fire in a battery structure comprising a plurality of battery packs and a fluid storage part configured to store an electrically insulative fire extinguishing fluid, the method comprising:
- detecting, by a gas detection member provided in a casing part of a battery pack, a gas generated in the casing part;
- transmitting a detection signal from the gas detection member to a control member;
- operating, by the control member, a valve member provided in a piping line connected between the fluid storage part and the battery pack;
- and
- injecting the fire extinguishing fluid from the fluid storage part into the casing part of the battery pack through the piping line.
