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.

A fire suppression apparatus includes a valve assembly connected to a container holding a fire suppressant. The valve assembly includes a valve body and a first disc. The valve body defines a passageway that extends between a first valve body end and a second valve body end. The first disc is disposed within the passageway. The first disc has a first disc body defining a perforation that extends completely through the first disc body.

Systems and methods for fire suppression systems are disclosed. The methods may include operating the fire suppression system in a first configuration. The methods may further include shifting the fire suppression system from the first configuration to a second configuration in which pumping of foam concentrate to the upstream side of the water pump is stopped and in which foam concentrate is pumped to a downstream side of the water pump. The fire suppression system may be operated in the second configuration whereby a portion of the water pumped from the water pump is combined with foam concentrate to supply a first one of the plurality of manifolds, and another portion of the water pumped from the water pump is provided without foam concentrate to supply a second one of the plurality of manifolds.

A fire extinguishing system for a vehicle includes a fire detection device outputting a fire detection signal in response to detecting a fire and is installed in a predetermined space of the vehicle. A controller outputs a control signal for spraying fire extinguishing agent when the fire detection signal is received from the fire detection device. An air tank stores compressed air and a fire extinguishing agent cylinder is connected to the air tank through an air hose, is filled with the fire extinguishing agent, and is operated to discharge the fire extinguishing agent by the compressed air, supplied from the air tank through the air hose, by the control signal. A spray nozzle assembly is connected to the fire extinguishing agent cylinder through a fire extinguishing agent hose and sprays the fire extinguishing agent being supplied, from the fire extinguishing agent cylinder, through the fire extinguishing agent hose.

The present disclosure provides a spray system for a battery pack and a battery pack. The spray system includes a spray pipeline configured to circulate a spray liquid and form an opening when being heating, a liquid storage device communicating with the spray pipeline, and a driving device including a driving component and an elastic component connected to the driving component. The driving component, under an elastic force applied by the elastic component, drives the spray liquid in the liquid storage device to flow into the spray pipeline. In the present spray system, the spray liquid not only in the spray pipeline but in the liquid storage device can be discharged to spray, thereby improving the spray effect, preventing the heat flow generated when the one battery unit is thermally out of control from spreading to the adjacent battery units, and improving the safety of the battery pack.

A fire extinguishing system for a tire of a vehicle is capable of effectively responding to a fire in all tire areas of the vehicle, and of spraying fire extinguishing agent selectively only for the tire having the fire, thereby performing effective fire extinguishing. The fire extinguishing system includes: a fire detection sensor configured to detect the fire in the tire of the vehicle; a fire control unit configured to receive a signal output from the fire detection sensor and to output a control signal for spraying fire extinguishing agent when the fire control unit determines a fire occurrence; and a plurality of fire extinguishing agent sprayers configured to spray the fire extinguishing agent toward the tire having the fire according to the control signal output by the fire control unit, in a state of being filled with the fire extinguishing agent therein

Systems and methods for fire suppression, a fire suppression system including a container configured to receive frames, each of the frames including battery modules; a pipe system including at least one vertically extending pipe, the at least one vertically extending pipe configured to be provided between a respective two of the frames and configured to supply suppressant to at least one of the battery modules of each of the respective two of the frames via slots of the vertically extending pipe; at least one tank connected to the pipe system and configured to store the suppressant; at least one pump configured to recirculate the suppressant to the pipe system or a tank of the at least one tank; and an inlet body configured to connect with a suppressant source, that is external to the container, to provide new suppressant into the pipe system or the at least one tank.

The network enabled fire sensor and fire extinguishing system is a fire-fighting apparatus comprising a plurality of extinguisher modules. The plurality of extinguisher modules forms a wireless communication link between: a) the plurality of extinguisher modules, and, b) with an appropriate authority. When triggered by fire, the individual extinguisher module: c) releases a fire extinguishing chemical; and, d) transmits an alert message to both the appropriate authority and to the individual extinguisher modules remaining in the plurality of extinguisher modules containing the GPS coordinates of the transmitting individual extinguisher module. Each selected individual extinguisher module compares the GPS coordinates of the selected individual extinguisher mode to the GPS coordinates of the module alert message. If the span of the distance between the two coordinates is less than a previously determined span of distance, than the selected individual extinguisher module releases a fire retardant chemical.

A fire apparatus includes an engine, a fluid delivery system, and a controller. The fluid delivery system includes a first pump that provides a first fluid output at a first pressure, and a second pump positioned downstream of and coupled to the first pump in a serial arrangement. The second pump is driven by the engine. The second pump provides a second fluid output at a second pressure. During a first mode, the first fluid output is dischargeable from a low pressure discharge. During a second mode, the second fluid output is dischargeable from a first high pressure discharge and/or a second high pressure discharge, the engine operates at a first set point when the second fluid output is discharged from the first high pressure discharge, and the engine operates at a second set point when the second fluid output is discharged from the second high pressure discharge.
