Description

Technical Field

[0001] This invention relates to the field of energy storage equipment technology, and in particular to a hybrid chemical energy storage device. Background Technology

[0002] Hybrid chemical energy storage devices are composite systems that integrate two or more chemical energy storage technologies. By synergistically combining the advantages of different energy storage media, they enhance overall performance. Common combinations include lithium-ion batteries and flow batteries, lead-acid batteries and supercapacitors, etc. The core of the device consists of an energy storage module, an energy management system, and a bidirectional converter. The EMS (Energy Management System) dynamically allocates power through algorithms, optimizes charging and discharging efficiency, and adapts to scenarios such as grid peak shaving and renewable energy consumption. It has a response speed as fast as milliseconds and combines stability and flexibility. Compared with single energy storage technologies, this device can balance cost, lifespan, and power requirements. It is widely used in new energy power plants, microgrids, and electric vehicles and is an important solution to the problem of intermittent energy storage.

[0003] However, traditional energy storage devices mostly employ single fire suppression measures, which cannot address the differentiated risks of hybrid energy storage units. Lithium-ion batteries are prone to thermal runaway, while flow batteries pose a risk of electrolyte leakage and corrosion, and lack early warning mechanisms. Fault propagation paths between different energy storage units are not effectively blocked. For example, the high temperatures and toxic gases generated by thermal runaway in lithium-ion batteries can accelerate the decomposition of electrolyte in flow batteries, while electrolyte leakage in flow batteries can corrode the electrode materials of lithium-ion batteries, leading to an increased risk of secondary disasters.

[0004] Therefore, how to improve the protective effect and reduce the risk is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0028] The drainage mechanism includes a drainage block disposed at the bottom of the energy storage unit and a leakage trough disposed on the outer casing of the device. The drainage block has a guiding surface, with its high end close to the energy storage unit, and the leakage trough is located at the bottom end of the guiding surface.

[0029] Optionally, the above-mentioned hybrid chemical energy storage device satisfies at least one of the following:

[0030] The diversion mechanism also includes a plurality of grid plates disposed on the guide surface, and a diversion channel for diverting the electrolyte is formed between two adjacent grid plates, and the diversion channel extends from the high end to the bottom end of the guide surface;

This allows the isolation chambers and the isolation structure to form multiple physical isolation units, ensuring that when an energy storage unit in one isolation chamber fails (such as thermal runaway, electrolyte leakage, or other risks), it cannot propagate to other isolation chambers. This effectively blocks the failure propagation path of different energy storage units, improves the protection effect, reduces the risk diffusion rate, and enhances the overall safety of the hybrid chemical energy storage device.

[0058] All terms used in this disclosure have the same meaning as understood by one of ordinary skill in the art to which this disclosure pertains, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and not as idealized or highly formalized, unless expressly defined herein.

[0059] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0060] like Figures 1-9 As shown, this embodiment of the invention provides a hybrid chemical energy storage device, including a device housing 1, energy storage units 6, an isolation structure, and a control mechanism. The device housing 1 contains multiple isolation chambers 5; at least two isolation chambers 5 contain energy storage units 6; adjacent isolation chambers 5 are separated by an isolation structure, which has a first state and a second state. In the first state, adjacent isolation chambers 5 are interconnected; in the second state, adjacent isolation chambers 5 are isolated from each other. The control mechanism can control the isolation structure to switch between the first and second states.

[0061] The hybrid chemical energy storage device provided in this embodiment of the invention has multiple isolation chambers 5 arranged inside the outer shell 1 to accommodate different energy storage units 6. An isolation structure is provided between two adjacent isolation chambers 5 to isolate the two isolation chambers 5 from each other, so that the isolation chambers 5 and the isolation structure form multiple physical isolation units. This ensures that when an energy storage unit 6 in one isolation chamber 5 fails (such as thermal runaway, electrolyte leakage, or other risks), it cannot propagate to other isolation chambers 5. This effectively blocks the failure propagation path of different energy storage units 6, improves the protection effect, reduces the risk diffusion rate, and enhances the overall safety of the hybrid chemical energy storage device.

[0062] Among them, the energy storage unit 6 can be a battery pack or a storage battery, etc.

[0063] In some embodiments, the isolation structure may include a protective sleeve 14 disposed between two adjacent isolation chambers 5 and an isolation door 15 movably disposed inside the protective sleeve 14, with a control mechanism capable of controlling the movement of the isolation door 15. The protective sleeve 14 may be fixed relative to the device housing 1, while the isolation door 15 may move relative to the device housing 1. That is, the control mechanism can control the movement of the isolation door 15 relative to the device housing 1, allowing the isolation door 15 to move within the protective sleeve 14. The change in the structure of the isolation door 15 and the protective sleeve 14 allows the isolation structure to switch between a first state and a second state. For example, in the first state, the isolation door 15 is at least partially moved out of the protective sleeve 14, allowing the two adjacent isolation chambers 5 to communicate with each other; in the second state, the isolation door 15 closes the area inside the protective sleeve 14, isolating the two adjacent isolation chambers 5 from each other. The structure of the isolation door 15 and the protective sleeve 14 can isolate the two adjacent isolation chambers 5. Alternatively, the isolation structure may consist only of the isolation door 15, with the movement of the isolation door 15 relative to the device housing 1 enabling the switching between the first and second states.

[0064] The control mechanism includes a controller 2, a drive component 17, and a transmission assembly. The controller 2 is mounted on the outside of the device housing 1. The device housing 1 has a slot 4 located below the isolation chamber 5. The drive component 17 is disposed within the slot 4 and electrically connected to the controller 2. The transmission assembly connects the drive end of the drive component 17 to the isolation door 15, thereby driving the isolation door 15 to move up and down relative to the protective sleeve 14. The drive component 17 can be a servo motor or a cylinder, etc. The controller 2 can control the start and stop of the drive component 17 based on received signals (such as temperature signals, humidity signals, or image signals indicating a fault in the energy storage unit 6), thereby driving the isolation door 15 to move relative to the protective sleeve 14 via the transmission assembly.

[0065] Alternatively, the empty slot 4 can be positioned on the side or above the isolation chamber 5. The movement of the isolation door 15 relative to the protective sleeve 14 can also be horizontal movement or rotation, etc., without specific restrictions and all are within the protection range.

[0066] The transmission assembly includes a worm gear 18, a worm wheel 19, a first threaded component 20, and a second threaded component 21. The worm gear 18 is rotatably mounted inside the device housing 1 and connected to the drive end of the drive component 17; the worm wheel 19 meshes with the worm gear 18 and is rotatably connected to the device housing 1; the first threaded component 20 is coaxially connected to the worm wheel 19; and the second threaded component 21 is threadedly engaged with the first threaded component 20 and connected to the isolation door 15. It can be understood that there can be one worm gear 18, and multiple worm wheels 19, first threaded components 20, and second threaded components 21, each corresponding to one of the multiple isolation doors 15.

[0067] The worm gear 18 meshes with multiple worm wheels 19, which can synchronously drive multiple isolation doors 15 to move. Compared with the structure of controlling the isolation door 15 separately, it effectively reduces the complexity of the control logic and ensures that in an emergency, multiple isolation chambers 5 (all isolation chambers 5) can be isolated or opened at the same time, avoiding the situation where the protection fails due to the delay of a single component (such as the isolation door 15).

[0068] The drive component 17 within the empty slot 4 is electrically connected to the controller 2. The controller 2 can precisely control the rotation of the worm gear 18 via its program. Compared to manually driving the isolation door 15, this allows for rapid opening and closing of the isolation door 15. In the event of a malfunction in the energy storage unit 6 within an isolation chamber 5, it can quickly block the spread of risk and improve emergency protection efficiency. The drive component 17 is located on one side of the worm gear 18, while the other side of the worm gear 18 is rotatably connected to the device housing 1. For example, the worm gear 18 is rotatably positioned between the two sides of the device housing 1. This allows the worm gear 18 to be located inside the device housing 1, below the isolation door 15. Furthermore, the upper part of the worm gear 18 meshes with multiple worm wheels 19, and the lower part of the worm wheels 19 is rotatably connected to the device housing 1 via connecting components such as rotating shafts. For example, the worm wheels 19 are rotatably positioned on the inner bottom surface of the device housing 1.

[0069] One of the first threaded component 20 and the second threaded component 21 can be a threaded sleeve, i.e., it has internal threads, and the other of the first threaded component 20 and the second threaded component 21 can be a threaded rod, i.e., it has external threads. The internal thread of the threaded sleeve and the external thread of the threaded rod are threaded together. The extension and retraction of the two components in the direction of their rotation axis are achieved by the relative rotation of the two components. The top of the second threaded component 21 (such as the threaded rod) is fixedly connected to the bottom of the isolation door 15. The relative rotation of the first threaded component 20 and the second threaded component 21 enables the isolation door 15 to move closer to and away from the worm gear 19 (worm 18).

[0070] The rotational motion is converted into the linear lifting and lowering of the isolation door 15 by the threaded connection between the internal thread of the threaded sleeve and the external thread of the threaded rod, ensuring a tight fit between the isolation door 15 and the protective sleeve 14, thereby blocking the leakage path of toxic gases or electrolytes. Alternatively, the transmission assembly can be configured as a gear and rack drive structure.

[0071] To facilitate the movement of the isolation door 15 relative to the protective sleeve 14, the protective sleeve 14 has a sliding groove, and the isolation door 15 slides into the groove. This allows the protective sleeve 14 to have an internal sliding groove, which guides the movement of the isolation door 15, reducing the degree of deviation during movement (such as lifting), minimizing the swaying of the isolation door 15, preventing seal failure due to misalignment of the isolation door 15, ensuring the reliability of the physical barrier between the isolation chambers 5, and improving the stability of risk isolation.

[0072] The outer casing 1 has viewing windows 3 connecting its inner and outer walls, allowing observation of the interior of the outer casing 1. The outer casing 1 may have multiple viewing windows 3. The isolation door 15 includes a gate 16. The movement of the isolation door 15 controls the opening or closing of the gate 16 relative to the viewing windows 3. In a first state, the gate 16 is open relative to the viewing windows 3; in a second state, the gate 16 is closed relative to the viewing windows 3. That is, the isolation door 15 isolates two adjacent isolation chambers 5, and simultaneously closes the corresponding viewing windows 3 with its gate 16. This provides isolation protection between the isolation chambers 5 and the outside environment (outside the outer casing 1), further improving the isolation and protection effect and preventing the spread of risk.

[0073] A viewing window 3 can be provided on the front side of the device housing 1, and a gate 16 can be provided on the front side of the isolation door 15. The gate 16 can be raised and lowered synchronously with the isolation door 15, enabling the operation of opening or closing the viewing window 3 in conjunction with the isolation door 15. Compared with an additional switch structure for separately opening and closing the viewing window 3, this effectively reduces the number of mechanical parts, and can simultaneously shield the viewing window 3 during the closed operation of a single isolation chamber 5, preventing the diffusion of toxic gases through the viewing window 3, and simplifying the operation logic.

[0074] The hybrid chemical energy storage device provided in this embodiment of the invention further includes a drainage mechanism for guiding the leaked electrolyte from the energy storage unit 6 out of the isolation chamber 5. The drainage mechanism includes a drainage block 7 disposed at the bottom of the energy storage unit 6 and a leakage trough 9 disposed on the outer casing 1 of the device. The drainage block 7 has a guiding surface, with its high end close to the energy storage unit 6, and the leakage trough 9 located at the bottom end of the guiding surface. The two ends (high end and bottom end) of the guiding surface of the drainage block 7 have a height difference, so that the electrolyte leaked from the energy storage unit 6 due to a fault can reach the leakage trough 9 along the guiding surface, avoiding residual corrosion and reducing secondary hazards.

[0075] The guiding surface can be an inclined plane, an arc-shaped surface, or a corrugated surface, etc.

[0076] To further improve the guiding efficiency, the flow guiding mechanism also includes multiple grid plates 8 disposed on the guiding surface. A flow channel for diverting electrolyte is formed between two adjacent grid plates 8, and the flow channel extends from the high end to the bottom end of the guiding surface.

[0077] Furthermore, there are two guiding surfaces connected at their high ends. The drainage mechanism includes two leakage channels 9, each corresponding to the bottom end of one of the guiding surfaces. That is, the top surface of the drainage block 7 adopts a sloping design with a higher center and lower sides, allowing electrolyte leaked from the energy storage unit 6 due to a fault to flow along the two guiding surfaces to both sides (such as the front and rear sides of the energy storage unit 6) and into the corresponding leakage channels 9. In other words, the sloping structure (guiding surface) of the drainage block 7, with a higher center and lower front and rear, combined with the grid plate 8, can quickly guide the leaked electrolyte from the independent energy storage unit 6 into the leakage channels 9. Compared with a planar structure, this effectively reduces the amount of electrolyte remaining in the isolation chamber 5, preventing electrolyte corrosion of other components or secondary reactions. Furthermore, the structure of the grid plate 8 can also provide heat dissipation for the bottom of the energy storage unit 6 (battery pack).

[0078] The hybrid chemical energy storage device provided in this embodiment of the invention also includes a spraying mechanism for spraying fire-fighting media into the isolation chamber 5, so as to reduce secondary hazards.

[0079] The spraying mechanism includes a material box 10 and multiple distribution pipes 13 connected to the material box 10. Each distribution pipe 13 corresponds to an isolation chamber 5 and has a spray head. Each distribution pipe 13 has a switch valve to control its on / off state.

[0080] Among them, the fire-fighting medium in the material tank 10 (through the main material pipe 11) is diverted to different material pipes 13. By controlling the switch valve 12 (such as a solenoid valve) of each pipe individually, precise spraying is achieved in the isolation chamber 5 of the energy storage unit 6 where the fault is located, as well as spraying inside the overall device shell 1. This saves the amount of fire-fighting medium used and does not affect the normal operation of other energy storage units 6.

[0081] The switch valve 12 can be located at the connection between the main feed pipe 11 and the distribution pipe 13. That is, the fire-fighting medium in the feed hopper 10 enters the main feed pipe 11, flows through the open switch valve 12 into the connected distribution pipe 13. This allows the feed hopper 10 of the sprinkler system to be positioned above the isolation chamber 5, with the switch valve 12 installed above the distribution pipe 13 and sprinkler heads installed at the bottom of the distribution pipe 13, enabling the fire-fighting medium to flow from top to bottom within the distribution pipe 13.

[0082] The fire-fighting medium can be fluorinated liquid or other similar media.

[0083] The hybrid chemical energy storage device provided in this embodiment of the invention also includes multiple exhaust components disposed on the outer shell 1 of the device, each corresponding to an isolation chamber 5. By providing exhaust components, toxic gases generated by the energy storage unit 6 due to a malfunction can be filtered and emitted, effectively improving environmental safety. The exhaust components include an exhaust pipe 23 disposed on the outside of the outer shell 1 and an exhaust valve 22 controlling the connection between the exhaust pipe 23 and the isolation chamber 5. A filter screen is installed inside the exhaust pipe 23. An exhaust valve 22 and an exhaust pipe 23 connected to it can be installed on the top of the isolation chamber 5. The filter screen inside the exhaust pipe 23 can filter toxic gases such as those generated by electrolyte decomposition, improving the removal rate of harmful gases. The exhaust valve 22 forms a one-way exhaust design, preventing external gases from flowing back into the isolation chamber 5 and causing secondary reactions, effectively improving environmental compliance and reducing harm to operators and the environment.

[0084] The inner wall of isolation chamber 5 is made of rock wool sandwich steel plate to ensure the strength and isolation effect of isolation chamber 5.

[0085] like Figure 1 and Figure 10 As shown, the hybrid chemical energy storage device provided in this embodiment of the invention further includes an alarm device 24 and / or a temperature sensor 25, which are electrically connected to the control mechanism.

[0086] The device may include an alarm device 24 and a temperature sensor 25. Multiple combinations of the alarm device 24 and temperature sensor 25 can be used, each corresponding to one of the multiple isolation chambers 5. The alarm device 24 may be at least partially exposed outside the device housing 1. A temperature sensor 25 is located on the rear side of the alarm device 24 (the outer side facing away from the device housing 1) to detect the temperature inside the isolation chamber 5. The temperature sensor 25 is electrically connected to the controller 2 of the control mechanism. The temperature sensor 25 can monitor the temperature inside the isolation chamber 5 in real time. When the temperature exceeds a threshold, the alarm device 24 is immediately triggered, allowing operators to detect abnormalities early, buying time for fault handling, and reducing the risk of thermal runaway. Furthermore, the electrical signal of the temperature sensor 25 connected to the controller 2 of the control mechanism allows the control mechanism to switch the isolation structure from a first state to a second state when the temperature of one isolation chamber 5 exceeds the threshold. This prevents leaked electrolyte or toxic gases from the energy storage unit 6 within that isolation chamber 5 from spreading to other isolation chambers 5.

[0087] Alternatively, only alarm device 24 or temperature sensor 25 can be set.

[0088] The hybrid chemical energy storage device provided in this embodiment of the invention operates on the following principle:

[0089] Isolation and early warning mechanism: Temperature sensor 25 monitors the temperature inside each isolation chamber 5 in real time, and the data is transmitted to controller 2. When the temperature is abnormal (energy storage unit 6 malfunctions), alarm device 24 triggers an alarm. Controller 2 controls drive component 17 (servo motor) to drive worm gear 18 and worm wheel 19 to rotate. Through first threaded part 20 and second threaded part 21, isolation door 15 slides along the groove of protective sleeve 14, realizing the closed isolation of isolation chamber 5 (switching from the first state to the second state). Gate 16 simultaneously closes viewing window 3. During normal use (first state), viewing window 3 can provide ventilation.

[0090] Emergency handling and emission control: If the energy storage unit 6 leaks electrolyte, the diversion block 7 and grid plate 8 will guide the liquid into the leakage tank 9. If a fire occurs, the controller 2 will open the switch valve 12 (solenoid valve) of the corresponding feed pipe 13. The fire-fighting medium in the material tank 10 will be sprayed into the corresponding isolation chamber 5 through the main feed pipe 11 and the feed pipe 13. The gas in the isolation chamber 5 will enter the exhaust pipe 23 through the exhaust valve 22 and be discharged after being filtered by the filter screen.
