Background
The lithium ion battery has the advantages of high energy density, high output power, long charge and discharge life, no pollution, wide working temperature range, small self-discharge and the like, so that the lithium ion battery has wide application in the fields of electric automobiles, power grid energy storage systems and the like. The lithium battery energy storage system mainly comprises key equipment such as a battery energy storage unit, an energy conversion system, a battery management system and the like and is used for realizing the functions of peak clipping, valley filling, frequency modulation, voltage regulation and the like on the power distribution network side. The lithium battery energy storage unit is a unit set which consists of a plurality of lithium battery packs (modules) and circuit devices which are connected by a circuit and is placed in a sealed space, and is core equipment for energy bearing of an energy storage system. Because the lithium battery can generate a large amount of heat in the charge and discharge process, particularly under the abusive condition, the heat accumulation can easily cause the rapid temperature rise of the battery (module) to generate thermal runaway, thereby causing the fire explosion accident of the lithium battery. If the fire is prevented and controlled improperly or the fire is extinguished untimely, the fire is very likely to spread and expand to the peripheral energy storage units, so that large-scale fire explosion accidents are caused. Therefore, the configuration of the advanced and efficient fire extinguishing system has important significance for the safe operation of the energy storage system.
At present, the fire fighting and saving research on the fire disaster of the lithium ion battery energy storage unit has obvious defects, and the related fire fighting system is seriously lacking. The existing fire-fighting system is designed mainly with reference to electric fire disasters, and a fixed gas fire-extinguishing system is adopted. After a fire disaster occurs, the temperature sensing and smoke sensing detector arranged in the protection area gives out fire disaster alarm, the gas fire extinguishing system is started to spray fire extinguishing agent towards the fire area, and the whole area is protected in a total flooding mode. The traditional fire extinguishing system has a plurality of defects for extinguishing the fire of the lithium battery energy storage unit: (1) The fire extinguishing objects are usually equipment fires with larger fire intensity, and point-to-point fire extinguishing can not be carried out on fire sources in the closed space; (2) The fire extinguishing system has slow action time, and can be operated only after the detector receives fire signals such as high temperature or smoke and the like until the fire progresses to a larger scale, so that the optimal fire extinguishing time is lost; (3) The fire extinguishing agent is large in dosage, the fire extinguishing agent needs to be submerged in the whole protection area to effectively extinguish the fire, and the fire extinguishing effect is poor because the fire extinguishing agent cannot quickly permeate into the airtight equipment; in addition, most of fire extinguishing agents are carbon dioxide, inert mixed gas and other gases, so that the cooling effect is poor, and the fire extinguishing efficiency is low; (4) The fire extinguishing system has the advantages of complex structure, high requirement on installation environment, high investment cost and no remote mobile control function.
Obviously, the traditional fire extinguishing system cannot be suitable for preventing and early suppressing the early fire of the lithium battery, so that a novel intelligent fire extinguishing system is designed aiming at the lithium ion battery energy storage unit.

The specification of the spray head 10 needs to be determined according to parameters such as the volume of the lithium ion battery energy storage unit.
The fire control communication system includes: the fire control management system module 11, the fire control controller 6 and the fire control system controller 14 are used for realizing real-time bidirectional transmission of fire control system starting signals and instructions by the whole fire control communication system. The fire control management system module 11 integrates a pressure signal generator, a wireless signal receiver and the like, wherein the pressure signal generator is arranged at the tail part of the fire detection tube 5 and is used for monitoring the pressure change in the fire detection tube 5; the wireless signal generator is connected with the pressure signal generator through a circuit, receives the electric signal generated by the pressure signal generator, converts the corresponding electric signal into a wireless signal and sends the wireless signal, and the wireless signal can be received, identified and judged by the fire extinguishing system controller 14 arranged in the monitoring room, so that the working state of the fire extinguishing system is obtained.

The starting of the fire extinguishing system comprises two modes, namely a fire detecting tube 5 melting and breaking automatic fire extinguishing mode and a manual operation starting fire extinguishing mode. The specific implementation mode is as follows:
(1) The fire detecting tube 5 is melted and broken to automatically extinguish fire. When thermal runaway occurs or fire occurs in the energy storage battery 4 in the lithium ion battery energy storage unit, the surface temperature of the battery is rapidly increased, when the surface temperature of the energy storage battery 4 is higher than the breaking design temperature of the fire probe tube 5, the fire probe tube 5 attached to the surface of the energy storage battery 4 is melted and broken, so that the pressure in the fire probe tube 5 is rapidly reduced, and the release valve 8 is opened due to the pressure difference between the fire probe tube 5 and the fire extinguishing agent storage ball 7, so that the fire extinguishing agent in the fire extinguishing agent storage ball 7 is rapidly sprayed out through the first release port and is released to the ignition area of the energy storage battery or the position of the battery where the thermal runaway occurs at the breaking position of the fire probe tube 5, and the fire is rapidly extinguished or the abnormal temperature rise caused by the thermal runaway of the battery is cooled. At the same time, a pressure signal generator mounted at the tail end of the fire detector tube 5 detects the drop of the pressure in the tube and outputs an electric signal to a wireless signal generator, which converts the electric signal into a wireless signal and sends the wireless signal to the fire control system controller 14. The fire protection system controller 14 recognizes and judges the received signals, sends out fire alarm information, and uploads the fire alarm information, the started fire protection system and other signals to the fire protection system management host 15 and the fire protection system mobile terminal, so that the fire protection system management host 15 operators and the personnel holding the mobile client can acquire the fire alarm information, such as the fire occurrence position and the like.
(2) The manual operation initiates the fire suppression mode. When a worker finds that a fire disaster or thermal runaway occurs in a certain energy storage battery unit 4, and when the fire extinguishing device of the fire detecting tube 5 is not started in time, a fire extinguishing system starting signal can be sent out through an emergency starting button/key on any device of the fire extinguishing system controller 14, the fire extinguishing system management host 15 and the fire extinguishing system mobile terminal, the sent fire extinguishing system starting signal is converted into a wireless signal through the fire extinguishing system controller 14 and is received by a corresponding wireless signal receiver, the wireless signal receiver converts the wireless signal into an electric signal to be transmitted to the fire extinguishing controller 6, at the moment, the fire extinguishing controller 6 opens a control valve 9 so as to open a fire extinguishing agent storage ball 7, and after the fire extinguishing agent passes through the control valve 9 and a conveying pipeline 13, the fire extinguishing agent is sprayed to a fire area or a thermal runaway area by a spray head 10 to perform fire extinguishing or cooling treatment.
