Description

Technical Field

[0001] The utility model belongs to the technical field of energy storage safety, and specifically relates to an energy storage protection device and an energy storage fire protection system. Background Art

[0002] With the rapid development of the new energy industry, energy storage devices (particularly lithium-ion batteries) are increasingly being used in electric vehicles, energy storage power stations, and other fields. However, during the charging and discharging process, these energy storage devices may generate flammable gases due to overheating, short circuits, and other factors, which can cause fires or explosions, posing serious threats to personnel safety, equipment assets, and the environment.

[0003] To improve the safety of energy storage equipment, existing technologies often use independent gas detection devices and fire extinguishing systems (such as suppression nozzles). The gas detection device is responsible for monitoring the concentration of combustible gases within the energy storage device and issuing an alarm if an anomaly is detected. The fire extinguishing system is usually deployed as a standalone device, initiating the fire extinguishing process upon receiving a fire alarm. However, this separate monitoring and fire extinguishing method has problems such as slow response speed, imprecise control, and high equipment costs, making it difficult to meet the high safety and reliability requirements of large-scale energy storage systems.

[0013] In the second aspect, the utility model proposes an energy storage fire fighting system, including the energy storage protection device as described above, and also including an energy storage device, the energy storage device is provided with a multi-functional interface, and the pipeline 2 led out from the pipeline interface leads to the energy storage device through the multi-functional interface, which is used to realize the collection of combustible gas and the injection of fire suppression agent.

[0014] Furthermore, the energy storage fire-fighting system includes at least two of the energy storage devices, and the pipeline 2 is provided with a three-way joint and a two-way joint.

The energy storage protection device and fire protection system of this application integrates combustible gas concentration collection and fire suppression agent injection functions to achieve real-time monitoring and rapid response to the internal environment of energy storage equipment (such as battery packs). When the combustible gas concentration is detected to exceed the safety threshold, the system automatically switches to fire suppression mode and quickly injects the agent to suppress the fire, thereby significantly improving the safety and reliability of the energy storage equipment and effectively preventing fire accidents.

Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Example 1

[0025] like Figure 2 As shown, this embodiment proposes an energy storage protection device, including a reagent bottle 23, a three-way valve 24 (specifically a three-way solenoid valve), a control module 25, a collection module 26 (including a gas sensor), and a pipeline interface 22; the collection module 26 is connected to the three-way valve 24 and the pipeline interface 22 in sequence to form a collection channel for collecting the combustible gas concentration of an external energy storage device (such as a battery pack); the reagent bottle 23 is connected to the three-way valve 24 and the pipeline interface 22 in sequence to form an agent channel for storing and spraying a fire suppression agent; the control module 25 is signal-connected to the collection module 26 and the three-way valve 24 (specifically connected through a communication line 6), and is used to control the agent channel to form a passage when the combustible gas concentration exceeds a set value.

[0026] More specifically, a medicine pipeline 27 is provided between the medicine bottle 23 and the first branch of the three-way valve 24, a collection pipeline 28 is provided between the collection module 26 and the second branch of the three-way valve 24, and a pipeline 29 is provided between the third branch of the three-way valve 24 and the pipeline interface 22. Pipeline 29 is used for inhalation of combustible gas or spraying of fire suppression agent.

[0027] For example, during specific use, the protective device is equipped with a fire extinguishing agent bottle and a collection module 26. Both are connected to a three-way solenoid valve via pipes. The three-way solenoid valve is connected to the control module 25 (including the controller) via a wiring harness. The control module 25 can control the direction of the three-way solenoid valve. Directed collection and suppression of external battery packs, thereby completing gas collection and fire suppression functions.

[0028] The protection device also includes a communication interface 21 connected to the control module 25. The communication interface 21 is used to connect to an external energy storage device and to control the collection channel to directionally collect the combustible gas concentration of the energy storage device.

[0029] Example 2

[0030] like Figure 1 and Figure 2 As shown, this embodiment proposes an energy storage fire protection system, including the energy storage protection device 2 proposed in Example 1, and also including an energy storage device 1 (such as a battery pack). The energy storage device 1 is provided with a multi-function interface 11. The pipeline 2 3 leading from the pipeline interface 22 is connected to the energy storage device 1 through the multi-function interface 11, which is used to realize the collection of combustible gas and the injection of fire suppression agent.

[0031] Further preferably, the energy storage fire protection system includes at least two energy storage devices 1. A three-way connector 4 and a two-way connector 5 are provided on pipeline 2 3. The three-way connector 4 distributes pipeline 2 3 to the multifunctional interface 11 of each energy storage device 1. The terminal energy storage device 1 is connected to pipeline 2 3 via the two-way connector 5. The multifunctional interface 11 on each energy storage device 1 is signal-connected to the communication interface 21 for targeted collection of combustible gas from each energy storage device and fire suppression for each energy storage device.

[0032] For example, during specific use, the control module 25 controls the switching of the three-way solenoid valve. The three-way solenoid valve is connected to the pipeline interface 22, and then to the multi-function interface 11 on the battery pack through the pipeline 2 3. It is then connected to each battery pack in sequence through the three-way connector 4. The last battery pack is connected to the multi-function interface 11 via the two-way connector 5. Each multi-function interface 11 is connected to the communication interface 21 via the communication line 6. The communication interface 21 is connected to the control module 25, thereby realizing the control of the multi-function interface 11 on each battery. When the energy storage fire protection system begins operation, the three-way solenoid valve path in the protection device 2 is switched to the collection channel (collecting combustible gas concentration). The solenoid valve switch of the multi-function interface 11 installed on each battery pack is opened in sequence (only one is opened at a time, and the others are closed). Gas collection is carried out in sequence. When the gas value in one of the battery packs is detected to exceed the standard, an alarm is issued. At this time, the three-way solenoid valve path in the protection device 2 is switched to the suppression agent path. The agent bottle 23 is opened, and the agent enters the multi-function interface 11 on the corresponding battery pack to suppress the fire in the battery pack and realize the product function.

[0033] It should be noted that, in this embodiment, the multifunctional interface 11 can be installed on the outer side wall of the battery pack to collect gas inside the pack and perform fire suppression.
