[0036] An embodiment of the present invention provides a method and system for discharging smoke from an energy storage system, which is used to discharge smoke from a battery 700. The smoke discharging system of the energy storage system includes at least one smoke collecting element 100, an air pipe assembly, a first detection assembly, a second detection assembly 400, an alarm assembly 500, and a control system 600.

The temperature detector 310 is used to detect the temperature state of the battery 700, and the voltage detector 320 is used to detect the temperature state of the battery 700. 0 voltage state; the second detection component 400 is arranged in the air pipe component, and the second detection component 400 includes a smoke detector 410 and a gas detector 420, and the smoke detector 410 and the gas detector 420 are used to detect the gas production state of the battery 700; the alarm component 500 is arranged outside the battery 700, and the alarm component 500 is electrically connected to the first detection component and the second detection component 400, and the alarm component 500 is used to alarm according to the preset signals of the first detection component and the second detection component 400; the control system 600 is used to receive the signals of the first detection component and the second detection component 400, control the alarm component 500 to open or close, and execute the preset fire action logic of the air pipe component.

[0037] By adopting the smoke collecting component 100 to be connected to the safety valve 710 of the battery 700 and directional discharge through the air pipe assembly, the first detection component and the second detection component 400 can timely monitor the temperature, voltage, smoke and gas status of the battery 700, and can monitor the working status of the battery 700 in real time. The smoke detector 410 and the gas detector 420 can detect the smoke and gas produced by the battery 700 and send out an alarm signal in time. The air pipe assembly discharges the smoke in the battery 700 through the smoke collecting component 100, effectively controlling and eliminating the harmful gases and smoke that may be produced by the battery 700. The alarm component 500 realizes real-time monitoring and early warning of the state changes of the battery 700 by connecting the first detection component and the second detection component 400. The control system of the control system 600 receives and processes the signals from the detection component, and can automatically open or close the alarm component 500 according to the preset logic, execute the fire-fighting action of the air pipe assembly, and realize safe and directional discharge of the smoke from the battery 700.

[0038] In some embodiments, the air pipe assembly includes a power part 220 and a gas pipeline 210, one end of the gas pipeline 210 is connected to the smoke collecting part 100, and the other end of the gas pipeline 210 is connected to the power part 220. The power part 220 is a device for driving the smoke exhaust of the battery 700, and generates sufficient airflow or negative pressure by mechanical or electrical means to extract or discharge smoke or gas from the smoke collecting part 100. The gas pipeline 210 is a pipeline system connecting the power part 220 and the smoke collecting part 100. It is mainly used to transmit smoke or harmful gases from the smoke collecting part 100 to the power part 220, and then to be processed or discharged. One end of the gas pipeline 210 is connected to the smoke collecting part 100 to introduce the smoke into the pipeline system. The gas pipeline 210 can effectively remove the generated smoke or harmful gases from the battery 700 or the energy storage system, and process or discharge them through the power part 220.

[0039] In some embodiments, the trachea assembly further includes a main line 211 and a branch line 212, one end of the branch line 212 being connected to the smoke collecting component 100, and the other end of the branch line 212 being connected to the main line 211. The main line 211 is the main transmission channel of the trachea assembly, responsible for collecting or concentrating the smoke or gas transmitted from multiple branch lines 212 from the power component 220. The branch line 212 is a small pipe branching out from the main line 211, one end of which is connected to the smoke collecting component 100, and the other end is connected to the main line 211. The branch line 212 effectively transports the smoke or gas generated in the smoke collecting component 100 to the main line 211, which is then processed or discharged by the power component 220. Each branch line 212 can be connected to a different smoke collecting component 100 as needed to achieve diversion or centralized processing.

[0040] In some embodiments, a power component 220 is disposed within the main conduit 211 and is an explosion-proof power component 220 or an air pump. This explosion-proof power component 220 or air pump can effectively prevent the smoke or harmful gases generated by the battery 700 from sparking or coming into contact with the power equipment, thereby avoiding the risk of fire or explosion. The explosion-proof power component 220 or air pump has high power transmission efficiency and strong airflow propulsion capabilities, effectively extracting or pushing smoke from the smoke collection element 100 and discharging it into the main conduit 211 for further processing or discharge to a safe area.

[0041] In some embodiments, the outer surface of the battery 700 is further provided with a safety valve 710, and the smoke collecting member 100 covers the safety valve 710 and forms a sealed structure with the outer surface of the battery 700. The shape of the smoke collecting member 100 can vary according to the structure of the safety valve 710, including but not limited to cylindrical, elliptical cylindrical, cuboid, and circular truncated cone. The smoke collecting member 100 covers the safety valve 710 and forms a sealed structure, which can ensure that the battery 700 system remains closed during normal operation, helping to prevent dust, moisture, or other contaminants in the external environment from entering the interior of the battery 700, and also preventing the release of gas or liquid from the interior of the battery 700, ensuring that the safety valve 710 can operate normally. For example, when the internal pressure of the battery 700 abnormally rises, the safety valve 710 can safely release the pressure, and the smoke collecting member 100 safely collects and processes the released gas or liquid, avoiding the occurrence of fire, explosion, or other dangers.

[0042] In some embodiments, the battery 700 system includes at least one sub-pipe 212, and each sub-pipe 212 is connected to a smoke collecting member 100 that covers the safety valve 710 of the battery 700 and is connected to the main pipe 211 through the sub-pipe 212. Multiple sub-pipes 212 can be connected to different safety valves 710 in the battery 700 system. The control system 600 manages and monitors the gas release of multiple areas as needed, while avoiding unnecessary pressure accumulation. The pipe is responsible for collecting and transmitting smoke from each sub-pipe 212, making the management of the control system 600 more centralized and effective.

[0043] In some embodiments, the gas pipe assembly further includes a control valve 2121 disposed on the sub-pipe 212, and the sub-pipe 212 is connected to the main pipe 211 through the control valve 2121. The control system 600 is electrically connected to the control valve 2121 to execute a preset fire-fighting action logic. One battery 700 or multiple batteries 700 can be installed with one control valve 2121, and the control valve 2121 can be controlled to be opened or closed by the control system 600. The control valve 2121 adjusts and controls the flow of smoke in the sub-pipe 212, and can selectively open or close the sub-pipe 212 to connect to the main pipe 211 or operate independently. The control system 600 is electrically connected to each control valve 2121 to execute a preset fire-fighting action logic, including opening or closing a specific sub-pipe 212 under specific conditions, or actions performed by the control valve 2121 in response to a fire or other emergency situation. In the event of a fire or smoke leakage, the control system 600 can open the appropriate sub-pipe 212 through the control valve 2121 to release the gas to a safe area or perform other necessary control and management. The first detection assembly further includes a cabin ceiling detector 330 disposed in the battery 700, and the cabin ceiling detector 330 is electrically connected to the control system 600.

The air volume is 0-Am 3 / min, A takes a value of 0-1; real-time monitoring of the status of the smoke detector 410 and the gas detector 420. If no alarm occurs within 0-Bmin, B takes a value of 0-30, then the power component is turned off and the valve at the corresponding position is closed. If any detector in the smoke detector 410 or the gas detector 420 alarms within 0-Bmin, the alarm component 500 outputs a first-level alarm signal and reports it to the control system and the upper management system.
