PROBLEM TO BE SOLVED: To extinguish and suppress a fire by automatically detecting an electric fire caused by abnormality of a plurality of electric cells disposed in an electric storage device.SOLUTION: A plurality of electric cells 26 with a cylindrical shape are aligned and stored in a battery storage part 11a in a body storage container 11 of an electric storage device 10, and a smoking-fire extinguishing device 16 having a cylindrical shape with a same size as that of the electric cell 26 is disposed at an empty space of the battery storage part. The smoking-fire extinguishing device 16 has a heat detection cable functioned as a fire detection section laid in the storage container. When the heat detection cable receives heat by a fire and detects short circuit of a pair of signal lines due to melting of insulation coating, or an ignition control signal is input from the outside, an ignition circuit section energizes and heats a heater to ignite and burn a solid fire-extinguishing agent and to jet fire-extinguishing aerosol to the inside of the storage container and extinguish the fire. |
