Description

Technical Field

[0001] The present invention relates to the field of integrated electrochemical energy storage equipment, and in particular to an active protection type industrial and commercial energy storage cabin and a control method thereof. Background Art

[0002] Energy storage devices store electricity through batteries or battery packs. As power management equipment in industrial and commercial scenarios, industrial and commercial energy storage cabins focus on solving three key problems through efficient energy storage and intelligent scheduling:

[0003] 1. Peak shaving and valley filling: By combining the differences in peak electricity consumption in different time periods with the time-of-use electricity price metering strategy, the system charges the load from the grid during low-consumption periods and discharges the load during peak-consumption periods, thereby balancing power supply and demand and reducing overall electricity costs.

[0004] 2. Emergency power backup: to ensure emergency power supply and power supply continuity in the event of a power outage in the power grid, as well as to protect the safety of loads;

[0005] 3. Renewable energy integration, in conjunction with clean energy power generation equipment such as photovoltaics and wind power, plays a role in renewable energy absorption and fluctuation smoothing, as well as grid-connected power quality optimization and equipment protection.

[0006] Based on the above functions, industrial and commercial energy storage cabins are currently used in industrial and commercial scenarios such as large-scale photovoltaic energy storage sites and electric vehicle charging stations.

[0007] Existing industrial and commercial energy storage cabins can be roughly divided into two structural types: cabinet type and container type according to the scale of the equipment. The battery module installation generally adopts a stacking structure design. By designing multiple battery modules as a vertical or horizontal stacking structure and installing them in the cabin of the industrial and commercial energy storage cabin, a flexible assembly effect can be achieved.

[0008] For example, patent publication number CN118198636A describes an industrial and commercial energy storage cabin with a battery module protection assembly. The cabin utilizes multiple mounting locations within a mounting frame to stack battery modules and incorporates protective features to prevent damage from external impact. However, because industrial and commercial energy storage cabins are typically fixed and equipped with protective devices, the potential safety hazard stems from thermal runaway of the battery modules themselves, leading to high-temperature spontaneous combustion. A fire or explosion in one battery module can also cause combustion in nearby modules, potentially damaging the entire device. Summary of the Invention

[0057] The following is a further detailed description of the present invention in conjunction with specific embodiments and accompanying drawings. Obviously, the embodiments described are only a portion of the embodiments, not all of the embodiments. Based on the following embodiments, all other embodiments proposed by ordinary technicians in this field without creative work are also within the scope of protection of the present invention.

[0058] It should be understood that the controllers and control circuits involved in the embodiments are conventional control technologies or units for those skilled in the art. For example, the control circuit of the controller can be implemented by ordinary technicians in this field using existing technologies.

[0059] The disclosure of the embodiments provides many different implementations or examples for implementing different schemes of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described in the embodiments. Of course, they are merely examples and are not intended to limit the present invention. In addition, reference numerals and / or reference letters may be repeated in different examples in the embodiments. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various implementations and / or settings discussed. In addition, if examples of various specific processes and materials are provided in the embodiments, those of ordinary skill in the art will appreciate the application of other processes and / or the use of other materials.

[0060] The first embodiment of the present application mainly solves the problem that after a battery module expands or burns due to thermal runaway, its flame spreads inside the cabin, causing the adjacent battery modules to burn continuously.

[0061] Thermal runaway of an energy storage system refers to a process in which heat accumulation inside the battery triggers a chain reaction, causing the temperature to rise sharply and possibly causing a fire or explosion.

[0062] The internal temperature of the batteries in energy storage systems rises due to triggering factors such as overcharge / overdischarge, high temperature environments, mechanical damage (such as puncture and extrusion), internal short circuits, and manufacturing defects. When the temperature reaches approximately 80-120°C, the solid electrolyte interface film (SEI film) on the surface of the battery's negative electrode begins to decompose, releasing heat and generating combustible gases (such as CO and CH4). The decomposition reaction further accelerates the internal temperature rise. When the temperature rises to 120-150°C, the polymer separator (such as PE / PP) melts, and the positive and negative electrodes come into direct contact, leading to a more serious internal short circuit. The short-circuit current generates a large amount of heat, and the temperature rises exponentially. At high temperatures, the electrolyte (such as LiPF6 and carbonate solvents) decomposes, releasing large amounts of combustible gases (such as H2, CO, and C2H4). At the same time, the undecomposed electrolyte boils at high temperatures, and the internal pressure of the battery suddenly increases, which may cause the shell to expand, rupture, and explode. The flames spread and spray in all directions, causing the entire energy storage device to burn and be damaged.

[0063] To avoid such situations, existing energy storage devices utilize multiple approaches, including battery cell design (such as the use of stable materials like lithium iron phosphate), thermal management (liquid cooling / air cooling systems), BMS monitoring (real-time detection of voltage / temperature / internal resistance), and fire protection design (aerosol fire extinguishing, flame retardant insulation). Once a battery anomaly is detected, the system immediately shuts down, causing the entire system to stop functioning, minimizing risk. However, by the time an anomaly is detected, an irreversible chain reaction has often already occurred within the battery, and shutting down the power supply often fails to effectively prevent the situation from worsening. Immediately addressing the problem battery is essential. If addressed promptly, this not only maintains the normal operation of the energy storage system but also effectively prevents the spread of fire. The first embodiment of this application focuses on addressing such issues and describes the overall solution.

[0064] Since the embodiments of the present application mainly use the physical deformation of the battery module and the kinetic energy of the gas and liquid injection to generate component displacement and trigger the electrical signal as reference variables, even if the energy storage system executes shutdown and power-off control based on other parameters it detects, if the internal reaction of the battery module cannot be prevented, the release operation of the battery module can still be executed.

[0065] Because the battery's internal temperature and pressure rise before it catches fire during thermal runaway, and because temperature monitoring and control are separately implemented within the energy storage system, this embodiment uses the expansion of the battery module caused by the increase in internal pressure as the monitoring and triggering mechanism. The displacement described in this embodiment refers to the displacement of components in the direction of expansion caused by partial or complete expansion of the battery module, as well as the displacement of corresponding components caused by the pressure of the gas and liquid ejected during battery explosion.

[0066] In order to monitor the expansion of the battery module, the follower assembly of this embodiment includes a structural assembly or electronic component installed on the module frame corresponding to the side of the battery module and capable of generating displacement according to the lateral expansion of the battery module. The mounting portion can be horizontally or obliquely set, with the aim of covering as much lateral area of the battery as possible, so that the components performing the monitoring function can cover more battery areas. The functional parts in the follower assembly are components or structures that can generate electrical signals or physical deformations according to the expansion of the battery module. After the battery module expands, the functional parts in the follower assembly that contact the side wall of the battery module generate electrical signals or physical deformations to trigger subsequent execution.

[0067] like Figure 1-Figure 3As shown, the battery module 1 is composed of a module shell 101 and a plurality of battery packs 102 arranged inside the module shell 101. Each of the battery packs 102 is arranged in parallel with battery cells, and the positive and negative poles of adjacent battery cells 104 are connected in series through connecting pieces 103. The battery cells are then installed into a structural whole through end plates 105 and binding straps 106 at both ends. The existing battery cells 104 generally have an integrally formed metal shell, and one end face of the metal shell is an open face, which is used to install the pole 107 and related circuit connection components and then seal them. When thermal runaway occurs inside the battery cell, its internal pressure increases. Therefore, since the side of the pole 107 does not have a metal closed surface, it is this side that first expands and separates from the overall structure of the battery cell, or the direction in which the components melt and perforate due to high temperature and pressure and spray electrolyte and flames outward is also this side first. Therefore, the first embodiment mainly uses the expansion of this side as a triggering factor to establish a follow-up mechanism.

[0068] In the first embodiment, in order to prevent the fire from spreading to other battery modules or internal electrical modules when the battery module spontaneously combusts, the operation performed after obtaining the electrical signal or physical deformation is to move the battery module outside the box, and the execution of this operation is achieved through the module release component.

[0069] The connection between the follower assembly and the module release assembly described in this embodiment can be an electrical connection, a signal communication connection, or a mechanical transmission connection.

[0070] The module release assembly includes a bearing component that carries the battery module and stably mounts and fixes it in the module frame, and the bearing component releases the battery module from the vertical mounting position in response to the electrical signal or physical deformation.

[0071] During operation, when the follower component produces a corresponding state change according to the expansion of the battery module, an electrical signal or physical deformation is generated during the change process, and the module release component performs an execution action according to the electrical signal or physical deformation, and releases the load-bearing state of the load-bearing component at the bottom of the battery module. At this time, the battery module falls from the vertical installation position due to its own gravity and reaches the bottom of the cabin.

[0072] Due to the adoption of the above-mentioned scheme, the industrial and commercial energy storage cabin of the embodiment of the present application can sense the expansion of each battery module caused by thermal runaway, thereby releasing the deformed battery module from the module frame and transporting it to the outside of the industrial and commercial energy storage cabin, avoiding combustion and continuous combustion caused by the state of a single battery module, timely interrupting the battery module fire process, and playing a role in safety protection.

[0073] The first embodiment generally provides a structure and assembly that responds to the expansion state of a battery module caused by a thermal runaway reaction and proactively removes the battery module from the exterior of the industrial and commercial energy storage compartment. This can effectively prevent the impact on other battery modules or electrical components within the industrial and commercial energy storage compartment when the battery thermal runaway reaction cannot be prevented after the energy storage system is powered off and stopped. In addition to the overall structure and function, it mainly provides two corresponding release execution schemes based on displacement and electrical signals. The following describes the above two schemes in detail through the second and third embodiments, respectively.

[0074] The second embodiment provides an active protection type industrial and commercial energy storage cabinet based on the first embodiment, which generates structural movement according to physical deformation and controls the battery module to separate from the cabin.

[0075] Since the structures and functional settings in each embodiment are mainly aimed at an energy storage system composed of multiple stacked battery modules, the specific implementation is mainly aimed at industrial and commercial energy storage cabins, especially container-type industrial and commercial energy storage cabins. Therefore, the attached drawings take container-type industrial and commercial energy storage cabins as an example, but it does not rule out the possibility of use in conventional cabinet-type energy storage cabinets, or use in household energy storage systems through size adjustment.

[0076] like Figure 4 As shown, the industrial and commercial energy storage cabin of this embodiment includes a cabin body 2, which includes a battery module installation area 201 and a functional area 202. The battery module installation area 201 has a crossbeam 203 located above, and the battery modules 1 are hoisted in parallel on the crossbeam 203.

[0077] The functional area 202 is generally one or more of the following functional control areas:

[0078] The power conversion and control system area is used to install components such as the power storage converter (PCS), bidirectional energy metering devices, and automatic transfer switches (ATS); the thermal management and heat dissipation area is used to install components such as air cooling systems or liquid cooling units, as well as temperature sensors and controllers;

[0079] Management system area, used to install battery management system (BMS), energy management system (EMS), local interactive terminal and other devices;

[0080] Protection and fire protection area, used for installing fireproof partition walls and ventilation grilles, automatic fire extinguishing devices, combustible gas detectors and smoke probes, IP54 protection structures and other related devices or structures;

[0081] The electrical and auxiliary facilities area is used to install power distribution units, UPS power supplies, communication interfaces, etc.

[0082] In this embodiment, the functional area 202 is arranged on the upper part of the cabin 2. The above-mentioned areas can adopt different layout structures according to the scale and usage scenarios of the industrial and commercial energy storage cabin, or some areas can be selected for structural layout as needed. For example, it can also be arranged on one side of the cabin. Since the structural implementation in this embodiment is mainly aimed at the battery storage area, the layout and specific structure of other areas will not be elaborated.

[0083] Combine Figure 1-3 As shown, like the battery module 1 in the first embodiment, the battery module 1 in the second embodiment is composed of a module shell 101 and one or more battery packs 102 arranged in the module shell 101, and each battery pack 102 is composed of a plurality of battery cells 104. After the battery cells 104 are arranged side by side, they are formed into a structural entity through end plates 105 and binding straps 106 at both ends, and then the positive and negative poles of adjacent battery cells 104 are connected in series in sequence through connecting pieces 103 to form a battery pack.

[0084] Combine Figure 3 、 Figure 5 and Figure 6 As shown, the module shell 101 in the second embodiment is a hollow shell, the internal space of the hollow shell is used to install the battery pack 102, the module shell 101 is located on the side of the pole 107 of the battery pack 102 and is an open surface, the module shell and the battery pack together constitute the battery module 1, which is closed by a side cover plate 3.

[0085] In this embodiment, the side cover 3 serves as a follower component, and the module housing 101 is open on the side of the pole 107 of the battery pack 102 because when thermal runaway occurs inside the battery cell, the internal pressure increases. Since the pole 107 side needs to be installed with connecting components such as the pole ear to connect with the external pole, the probability of pressure release on this side is the highest. After setting this side as the trigger surface, when the battery cell expands or explodes, the pressure can be transferred to the side of the side cover 3 as quickly as possible, causing the side cover 3 to produce horizontal displacement. Based on this principle, the battery module can be released by moving the side cover 3.

[0086] Specifically, when installing the battery module 1, first place the module shell 101 horizontally, install the battery pack 102 in the module shell 101, so that the module shell 101 and the battery pack 102 are fixed in place as a whole, and then install the module shell 101 in the module frame 4, and then close the open surface of the module shell 101 through the side cover 3, while making the inner side of the side cover 3 close to the side of the pole 107 of the battery pack 102. The side cover 3 has a buckle 301 that is snapped onto the top and bottom of the module frame 4, and the module There is a movable support plate 401 on the bottom surface of the frame 4. After the side cover plate 3 and the module frame 4 are installed, the buckle 301 at the bottom of the side cover plate 3 supports the movable edge of the movable support plate 401. At this time, the module frame 4, the battery module and the side cover plate 3 are lifted as a whole to a vertical state. At this time, the weight of the battery module 1 acts on the movable support plate 401, pressing the movable support plate 401. Since the movable edge of the movable support plate 401 is supported by the buckle 301 at the bottom of the side cover plate 3, at this time, the module frame 4 and the battery module 1 form a vertical structural whole.

[0087] At this time, multiple assembled module frames 4 and battery modules 1 are hoisted in parallel to the battery module installation area 201 in the cabin 2 to form the following Figure 4 The industrial and commercial energy storage cabin structure shown.

[0088] Preferably, if Figure 6 As shown, in order to facilitate the installation and positioning of the side cover plate 3 and the module frame 4 , the four corners of the side cover plate 3 are provided with inner supports 302 that match the four corners of the open surface of the module frame 4 .

[0089] Furthermore, an insulating layer 303 may be provided on the inner side of the side cover 3. By tightly attaching the insulating layer 303 to the connecting piece mounted on the pole, the follow-up triggering can be made more accurate, and the invalid triggering distance caused by the gap between the side cover 3 and the battery pack can be reduced.

[0090] In terms of the specific structure of the movable support plate 401, the movable support plate 401 is installed on the bottom surface of the module frame 4 through the hinge 402. During operation, when the battery cell has thermal runaway, its pole side first expands outward, pushing the side cover plate 3 to move sideways. At this time, the buckle 301 on the side cover plate 3 detaches from the module frame and falls off. At the same time, the edge of the movable side of the movable support plate 401 loses support and flips downward along the hinge 402. The internal battery module 1 falls freely due to the action of gravity and falls outside the bottom of the cabin 2.

[0091] In terms of specific lifting structures, such as Figure 7 and Figure 8As shown, in this embodiment, the top of the module frame 4 has multiple groups of lifting brackets 403 arranged along the length direction of the top, and the middle of the lifting bracket 403 has a lifting gap 404. The module frame 4 is lifted in the cabin 2 through the lifting longitudinal beam 5, and the lifting longitudinal beam 5 passes through the lifting bracket 403 from the lifting gap 404.

[0092] Preferably, a fire pool or other transfer mechanism can be provided at the bottom of the cabin to promptly extinguish or transfer abnormally functioning battery modules, so as to protect other battery modules in the cabin.

[0093] The second embodiment described above realizes the detection and release of battery module expansion by component displacement. The third embodiment below further proposes a structural form of control and execution by electrical signals.

[0094] Based on the overall structure of the first and second embodiments, the third embodiment only describes the structure of the battery module installation area in the cabin, such as Figures 9-11 As shown, in the third embodiment, the cabin 2 is staggered with multiple layers of module frames 4, each of which is equipped with a battery module 1. The multi-layer staggered arrangement means that the vertical mounting positions are arranged in multiple layers in the vertical direction. The module frames 4 in each layer are hoisted in a horizontal parallel manner, with at least two layers. The multiple layers do not overlap or partially overlap in the vertical direction. This arrangement structure can ensure that when the battery module 1 is installed in the vertical mounting position, it maintains sufficient spacing from the adjacent battery modules 1 in the lateral direction, which is beneficial for heat dissipation. It also allows for a certain amount of installation space on both sides of the battery module 1 to set up the relevant structure of this embodiment. In actual installation, if the installation space has sufficient length or width space, a single-layer installation as in the second embodiment can also be adopted, that is, the vertical mounting positions are installed side by side at the same height in the length direction, and on this basis, a certain amount of staggered arrangement can be performed in the width direction. Regardless of which structure is adopted, in this embodiment, it is necessary to ensure that the battery modules do not overlap in the vertical direction, that is, there is no intersection in the projection area of the battery modules on the horizontal plane, so that the battery modules 1 can be subsequently lowered and removed.

[0095] In this embodiment, the module frame 4 has a vertical installation space, that is, when the battery module is installed in the vertical installation position, it is also in a vertical state.

[0096] As a preferred solution, the two end faces of the module frame 4 have open surfaces, the open surface on one side is used to insert the battery module into the module frame, and the open surface on the opposite side is used to connect the battery module's connection terminals with the connection terminals in the module frame after the battery module is inserted into the vertical mounting frame to achieve circuit connectivity.

[0097] In this embodiment, follower components are respectively provided on both sides of the module frame 4, and the follower components monitor the status of the battery module and generate electrical signals according to the changes in the status of the battery module; the follower components include structural parts and functional parts, and the structural parts represent structural installation components for installing the follower components as a whole on both sides of the module frame, and the functional parts represent components that perform triggering functions.

[0098] A transfer bin is located at the bottom of the cabin (not shown in the accompanying drawings). After the battery modules are released, they fall into the bin. A drive mechanism is located at the bottom of the bin to move the bin out of the cabin. Once the battery modules have fallen into the bin, the drive mechanism drives the bin to move horizontally out of the cabin's bottom.

[0099] Preferably, in order to prevent the transfer bin from occupying too much height, an arched, wavy or prismatic bottom surface may be provided at the bottom of the transfer bin so that the battery modules can fall naturally after falling into the transfer bin.

[0100] In the third embodiment, the cabin body 2 is the external structure of a container-type industrial and commercial energy storage cabin. The module frame 4 is hoisted on the crossbeam 203 through the column 204, and the module frame 4 is hoisted into a multi-layer staggered layout structure. The battery module 1 is installed in the module frame in a vertical state. The module frame 4 has a movable support plate 401, and the movable support plate 401 is installed with the bottom of the module frame through a hinge or other movable installation method. At the same time, an electromagnetic pin 405 is provided on the other side. The electromagnetic pin 405 is in an extended state under normal circumstances, supporting the openable and closable movable support plate 401. At the same time, a side crossbeam 406 is provided on both sides of the module frame 4. A plurality of signal sending components are arranged on the side crossbeam 406. The signal generating component is an induction switch 407. The induction switch has a compressible end 408 facing the battery direction. The compressible end 408 is installed close to the side wall of the battery module 1 under normal conditions. The closeness can be close or a small distance.

[0101] When the battery module malfunctions and expands, the compressible end 408 of the induction switch 407 is compressed by the expansion force of the battery module 1, generating an electrical signal. The electrical signal is directly or indirectly transmitted to the electromagnetic pin 405. At this time, the pin body of the electromagnetic pin 405 contracts, and the movable support plate 401 loses its support and flips downward under the action of the gravity of the battery module 1. At this time, an open surface is formed at the bottom of the module frame 4, so the battery module 1 can fall from the bottom of the module frame.

[0102] In order to ensure that this function can still be performed when the main system is powered off, the induction switch in this embodiment is a self-generating switch. The self-generating switch is a switching device that can work without an external power supply. Its core principle is to trigger energy conversion through mechanical action, converting mechanical energy into electrical energy, thereby powering the switch itself or external equipment. The signal processing unit and the electromagnetic pin are independently powered.

[0103] The fourth embodiment provides a control method for the industrial and commercial energy storage cabin based on the first and second embodiments. The main steps are centered around monitoring the battery status and generating and executing electrical signals. Figure 12 As shown, the control method of this embodiment includes:

[0104] S1. Arrange the battery modules horizontally and install them vertically in the industrial and commercial energy storage compartment.

[0105] S2 monitoring the deformation of the battery module;

[0106] S3 when the battery module is deformed, a displacement or electrical signal is generated according to the state change of the battery module;

[0107] S4. Release the battery module according to the displacement or electrical signal;

[0108] S5. Move the battery module outside the industrial and commercial energy storage cabin.

[0109] The above description is only a preferred embodiment of the embodiments of the present application, and does not limit the scope of disclosure of the embodiments of the present application. Any equivalent structure or equivalent process transformation made using the embodiment description and drawings of the present application, or directly or indirectly applied in other related technical fields, are also included in the scope of patent protection supported by the embodiments of the present application.
