Abstract
A battery structure includes a plurality of battery cells including electrodes and separators; a casing part defining an internal space configured to accommodate the battery cells; a piping line having a flow path formed therein, the piping line being connected to one side of the casing part; and a fluid storage part connected to one side of the piping line and configured to store an electrically insulative fire extinguishing fluid. The piping line is configured to deliver the fire extinguishing fluid from the fluid storage part into the internal space of the casing part in response to a thermal or pressure condition within the casing part.
Claims16
A battery structure comprising:
- a plurality of battery cells comprising electrodes and separators;
- a casing part defining an internal space configured to accommodate the plurality of battery cells;
- a piping line having a flow path formed therein, the piping line being connected to one side of the casing part;
- and
- a fluid storage part connected to one side of the piping line and configured to store an electrically insulative fire extinguishing fluid,
- wherein the piping line is configured to deliver the fire extinguishing fluid from the fluid storage part into the internal space of the casing part in response to a thermal or pressure condition within the casing part.
A method of controlling fire suppression in a battery structure comprising a plurality of battery cells accommodated in a casing part, the method comprising:
- determining, by a gas detection member provided in the casing part, whether a concentration of a gas in the casing part exceeds a predetermined threshold;
- transmitting, by the gas detection member, a signal to a control member in response to the concentration of the gas in the casing part exceeding the predetermined threshold;
- transmitting, by the control member, a control signal to open a valve member provided in an inlet piping line connected to a fluid storage part, such that the control member operates to control the valve member in response to receiving the signal from gas detection member;
- and
- supplying, through the inlet piping line, an electrically insulative fire extinguishing fluid stored in the fluid storage part into the casing part to suppress ignition.
