The present invention relates to a fire extinguishing system, which includes, inside a box-shaped mobile loading container having a sea water feeding and discharging structure, a plurality of battery cells for supplying power to an electric propulsion ship, and thus can quickly extinguish an electric fire occurring at sea while minimizing damage caused by the electric fire. A system for extinguishing a fire in a battery loading container in an electric propulsion ship, according to the present invention, comprises: a box-shaped mobile loading container including, at one side of the upper end thereof, an inlet valve for the inflow of fire-fighting water, including, at one side of the bottom thereof, an outlet valve for the discharge of the fire-fighting water, and including a power supply device comprising a plurality of battery cells in a space formed therein; a fire detector, provided at the upper side of the inside of the loading container, for detecting a fire by measuring the temperature inside the loading container; a feeding part for feeding the fire-fighting water to the inside of the loading container by using a pump and a feeding hose connected to the inlet valve; and a control unit for controlling operations of the inlet valve, the outlet valve, and the pump according to the temperature measured by the fire detector.

An automatic stovetop fire suppressor with suppressor activation triggering an audible alert of a fire condition and method are provided herein. A plastic bottom lid is secured to a bottom of a can, forming a closed container. A fire suppressing agent and a sound board are housed within the closed container. As the fire suppressor actuator is triggered, the bottom lid lowers releasing the fire suppressing agent and tripping a sound board alert switch. A microcontroller generates a desired fire condition signal which is played across a low voltage magnetic transducer. The suppressor is user friendly, provides an automated release of fire suppressing agent in the presence of a stovetop fire, and emits a continuing audible alert signal until a user disables the same. The fire suppressing agent and battery powered sound board are stored in the closed from manufactured end to activation of the suppressor in a fire condition.

The present application is provided with a fluid storage apparatus of a battery pack, including: a box, where the box has an inner cavity; a partition member, where the partition member is located in the inner cavity of the box, and the partition member divides the box into a fluid storage portion and a gas storage portion. The fluid storage portion is used to store spraying liquid and the fluid storage portion has a fluid outlet; the gas storage portion is used to store gas and the gas storage portion has a fluid inlet. And the partition member is configured to move toward the fluid outlet under the action of compressed gas in the gas storage portion.
