PROBLEM TO BE SOLVED: To provide a fire-extinguishing system for electric vehicles extinguishing and suppressing 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 having a flat-box shape are aligned and stored in a battery storage part in a body storage container 11 of an electric storage device, and a smoking-fire extinguishing device 16 having a flat-box shape with a same size as that of the electric cell 26 is disposed in an empty position of the battery storage position. The smoking-fire extinguishing device 16 has a heat detection cable 32 functioned as a fire detection section laid in the storage container. When the heat detection cable 32 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, ignites and burns a solid fire-extinguishing agent, and jets fire-extinguishing aerosol to the inside of the storage container and extinguishes the fire. |
