Description

Technical Field

[0001] This application relates to the field of energy storage equipment technology, and in particular to an operating parameter recorder and an energy storage device. Background Technology

[0002] Energy storage devices may experience thermal runaway under certain circumstances, leading to fire and deflagration inside the device. The data storage chips inside the device may fail due to the combined effects of fire and fire extinguishing liquids, making it impossible to recover the device's operating data before the thermal runaway, which is not conducive to post-accident analysis of the cause of the accident. Utility Model Content

[0003] In view of this, this application provides an operating parameter recorder and an energy storage device that can improve the safety of the chip module storing data under the influence of fire and fire extinguishing liquids.

[0004] One embodiment of this application provides an operating parameter recorder applied to an energy storage device. The operating parameter recorder includes an operating parameter recording component, a flame-retardant and heat-resistant component, and a bundling component. The operating parameter recording component includes a chip module and electrical connection wires. The outer side of the chip module is coated with waterproof adhesive. The electrical connection wires are connected to the chip module. The flame-retardant and heat-resistant component is constructed of aluminum silicate material and is configured to be flexibly deformable. The flame-retardant and heat-resistant component is wound around the outer side of the chip module. The flame-retardant and heat-resistant component forms a wiring channel. The electrical connection wires extend through the wiring channel to the outside of the flame-retardant and heat-resistant component. The bundling component is used to secure the flame-retardant and heat-resistant component, keeping it in a wound state.

[0005] The chip module connects to the battery management device of the energy storage equipment via electrical connection lines to record the equipment's operational data. The chip module is coated with a waterproof adhesive to prevent fire extinguishing liquids from contacting it. Flame-retardant and heat-insulating components, made of aluminum silicate, provide fire and heat insulation. By wrapping these components around the outside of the chip module, damage from fire or high temperatures is prevented, and the impact of fire or high temperatures on the waterproof adhesive is reduced, maintaining its waterproof effect. This provides double protection for the chip module. Bundling components keep the flame-retardant and heat-insulating components in a wound state, ensuring continuous fire and heat insulation protection and enhancing the overall effectiveness of the double protection for the chip module.

[0006] In some embodiments of this application, the flame-retardant and heat-resistant component includes a first wrapping component and a second wrapping component. The first wrapping component is wound around the outside of the chip module. The second wrapping component is wound around the outside of the first wrapping component.

[0007] The first and second wrapping components wrap the chip module sequentially from the inside out, giving the chip module a multi-layered structure for fireproofing and heat insulation. Furthermore, the first and second wrapping components are wound independently, which helps to prevent fire or high temperature from entering the chip module through the winding gaps of the flame-retardant and heat-insulating components, thereby improving the fireproofing and heat insulation effect of the chip module.

[0008] In some embodiments of this application, the axis corresponding to the first package winding intersects at least partially with the axis corresponding to the second package winding.

[0009] The first and second packages are wound around different axes. The second package can wrap around the side of the first package, thereby improving the protective sealing of the flame-retardant and heat-insulating components and enhancing the fireproof and heat-insulating effect.

[0010] In some embodiments of this application, a second package wraps around a first package to keep the first package in a wound state. A strapping member is fixed to the second package to keep the second package in a wound state.

[0011] By using a second package to secure the first package, the first package can be secured without the need for a strapping device, which helps to reduce the number of strapping devices used and thus lower production costs.

[0012] In some embodiments of this application, a portion of the binding member is disposed on the first package to maintain the first package in a wound state. A portion of the binding member is disposed on the second package to maintain the second package in a wound state.

[0013] After the first package is wrapped around the outside of the chip module, it is secured by a strapping device. Then, the second package is wrapped around the outside of the first package. The shape and structure of the first package are relatively fixed, which facilitates the wrapping of the second package and makes it easier to assemble the housing assembly.

[0014] In some embodiments of this application, a flame-retardant and heat-resistant component is wound to form a flame-retardant and heat-resistant cavity. The chip module is located within the flame-retardant and heat-resistant cavity. Waterproof adhesive is poured into the flame-retardant and heat-resistant cavity, bonding the chip module and the flame-retardant and heat-resistant component together.

[0015] Waterproof adhesive is injected into the flame-retardant and heat-resistant cavity to increase the seal between the flame-retardant and heat-resistant components and the chip module, thereby improving the waterproof effect. Furthermore, the chip module is bonded and fixed to the flame-retardant and heat-resistant components with waterproof adhesive, which helps reduce the movement of electrical connection wires to avoid affecting the structure at the wiring outlet, thus maintaining the fireproof, heat-insulating, and waterproof effect of the housing assembly at the wiring outlet.

[0016] In some embodiments of this application, the operating parameter recorder further includes a flame-retardant and heat-resistant plug and a waterproof plug. Both the flame-retardant and heat-resistant plug and the waterproof plug are located in the wiring channel. Electrical connection wires pass through the flame-retardant and heat-resistant plugs and extend to the outside of the flame-retardant and heat-resistant component. Furthermore, the flame-retardant and heat-resistant plug is closer to the outside of the flame-retardant and heat-resistant component than the waterproof plug.

[0017] By incorporating flame-retardant and heat-resistant plugs and waterproof plugs, the waterproofing, heat insulation, and waterproofing effects at the cable outlet are enhanced. Furthermore, with the flame-retardant and heat-resistant plug on the outside and the waterproof plug on the inside, the waterproof plug's failure due to fire or high temperatures is prevented, thus maintaining its waterproofing effectiveness.

[0018] In some embodiments of this application, the binding element is constructed as a rope-like structure made of flame-retardant and heat-resistant fibers and bound to the outside of the flame-retardant and heat-resistant element.

[0019] The rope-like structure allows the bundled components to be fixed by binding, which on the one hand reduces the difficulty of setting up the bundled components and makes them easier to assemble; on the other hand, it allows the thickness of the binding to be adjusted accordingly to accommodate flame-retardant and heat-resistant components with different outer diameters.

[0020] In some embodiments of this application, the binding element is constructed as a hoop structure made of metal material and is bound to the outside of the flame-retardant and heat-resistant element.

[0021] The hoop structure keeps the size of the bundle relatively fixed and provides good resistance to deformation, thus enabling the bundle to be stably fixed to the outside of the flame-retardant and heat-insulating component. This helps reduce the possibility of the flame-retardant and heat-insulating component detaching, thereby maintaining the fireproof and heat-insulating effect.

[0022] One embodiment of this application provides an energy storage device. The energy storage device includes a device housing, a battery module, a battery management device, and an operating parameter recorder as described in any of the above embodiments. The battery module and the battery management device are electrically connected and are both housed within the device housing. An electrical connection cable connects to the battery management device so that a chip module records the operating data of the battery management device.

[0023] The chip module is connected to the battery management device via electrical connection cables to record the operating data of the energy storage device. Furthermore, the chip module is protected by flame-retardant and heat-resistant components and waterproof adhesive to reduce the impact of fire and fire extinguishing liquids, enabling the chip module to reconstruct the operating data of the energy storage device and thus facilitating the analysis of the cause of an accident.

[0034] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0036] Energy storage devices may experience thermal runaway under certain circumstances, leading to fire and deflagration inside the device. The data storage chips inside the device may fail due to the combined effects of fire and fire extinguishing liquids, making it impossible to recover the device's operating data before the thermal runaway, which is not conducive to post-accident analysis of the cause of the accident.

[0037] This application provides an operating parameter recorder for use in energy storage devices. The operating parameter recorder includes an operating parameter recording component, a flame-retardant and heat-resistant component, and a bundling component. The operating parameter recording component includes a chip module and electrical connection wires. The outer side of the chip module is coated with waterproof adhesive. The electrical connection wires are connected to the chip module. The flame-retardant and heat-resistant component is constructed of aluminum silicate material and is configured to be flexibly deformable. The flame-retardant and heat-resistant component is wound around the outer side of the chip module. The flame-retardant and heat-resistant component forms a wiring channel. The electrical connection wires extend through the wiring channel to the outside of the flame-retardant and heat-resistant component. The bundling component is used to secure the flame-retardant and heat-resistant component, keeping it in a wound state.

[0038] The chip module connects to the battery management device of the energy storage equipment via electrical connection lines to record the equipment's operational data. The chip module is coated with a waterproof adhesive to prevent fire extinguishing liquids from contacting it. Flame-retardant and heat-insulating components, made of aluminum silicate, provide fire and heat insulation. By wrapping these components around the outside of the chip module, damage from fire or high temperatures is prevented, and the impact of fire or high temperatures on the waterproof adhesive is reduced, maintaining its waterproof effect. This provides double protection for the chip module. Bundling components keep the flame-retardant and heat-insulating components in a wound state, ensuring continuous fire and heat insulation protection and enhancing the overall effectiveness of the double protection for the chip module.

[0039] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0040] See Figures 1 to 3 One embodiment of this application provides an operating parameter recorder 100 and an energy storage device 200.

[0041] In some embodiments, the energy storage device 200 has the functions of storing and discharging electricity for use as backup power for homes, production units, outdoor work, and outdoor recreation. The operating parameter recorder 100 is used to record the operating data of the energy storage device 200.

[0042] In some embodiments, the energy storage device 200 includes a device housing 201, a battery module 202, and a battery management device 203. The battery module 202 and the battery management device 203 are electrically connected and are both disposed within the device housing 201. For example, the battery management device 203 may be a BMS (Battery Management System) board.

[0043] In some embodiments, the energy storage device 200 further includes a power conversion module (not shown). The power conversion module is electrically connected to the battery module 202 and is used to control the AC / DC conversion of the output current of the battery module 202. The energy storage device 200 equipped with the power conversion module can be a small portable power supply, a residential energy storage power supply, an industrial or commercial energy storage power supply, or a containerized energy storage power supply, etc.

[0044] In some embodiments, the power conversion module may be omitted. An energy storage device 200 without a power conversion module can be used independently. An energy storage device 200 without a power conversion module typically only outputs DC power. When used independently, an energy storage device 200 without a power conversion module can be used in conjunction with an energy storage device 200 with a power conversion module as a power system providing additional battery capacity.

[0045] In some embodiments, the energy storage device 200 further includes an operating parameter recorder 100. The operating parameter recorder 100 is disposed within the device housing 201 and connected to the battery management device 203. Exemplarily, both the operating parameter recorder 100 and the battery management device 203 are disposed within the housing of the battery module 202, with the operating parameter recorder 100 located next to the battery cells of the battery module 202 and avoiding the valve path of the battery cells. Figure 3 The structure indicated by the designation of battery module 202 is the battery cell of battery module 202.

[0046] See Figures 3 to 5 In some embodiments, the operating parameter recorder 100 includes an operating parameter recording component 10 and a flame-retardant and heat-resistant component 20. The operating parameter recording component 10 includes a chip module 11 and an electrical connection wire 12. The outer side of the chip module 11 is coated with a waterproof adhesive 111. The electrical connection wire 12 is connected to the chip module 11. The flame-retardant and heat-resistant component 20 is constructed of aluminum silicate material and is configured to be flexible and deformable. The flame-retardant and heat-resistant component 20 is wound around the outer side of the chip module 11. The flame-retardant and heat-resistant component 20 forms a wiring channel 21. The electrical connection wire 12 extends through the wiring channel 21 to the outside of the flame-retardant and heat-resistant component 20. The electrical connection wire 12 is connected to a battery management device 203. Exemplarily, the chip module 11 is a circuit board with data storage function; the waterproof adhesive 111 may be an organosilicon conformal adhesive.

[0047] Chip module 11 is connected to battery management device 203 of energy storage device 200 via electrical connection cable 12, enabling chip module 11 to record operating data of battery management device 203, particularly operating data of battery module 202 and battery management device 203. Chip module 11 is coated with waterproof adhesive 111 to prevent fire extinguishing liquids from contacting chip module 11. Flame-retardant and heat-insulating component 20 is made of aluminum silicate material, providing fireproof and heat-insulating functions. By wrapping flame-retardant and heat-insulating component 20 around the outside of chip module 11, assembly is convenient. This helps to prevent fire or high temperature from damaging chip module 11 and reduces the impact of fire or high temperature on waterproof adhesive 111, maintaining the waterproof effect of waterproof adhesive 111. Thus, chip module 11 is doubly protected, enabling chip module 11 to restore the operating data of energy storage device 200, thereby facilitating the review of accident causes.

[0048] Among them, the flame-retardant and heat-insulating component 20 is made of aluminum silicate material, which gives the flame-retardant and heat-insulating component 20 a high melting point and low thermal conductivity, so that it can maintain high stability under fire or high temperature and reduce the heat transferred inward.

[0049] Understandably, in some embodiments, during the winding process, gaps or areas may be left unsealed outside the chip module 11, thus forming the wiring channel 21. In other embodiments, the flame-retardant and heat-resistant component 20 may have openings to form the wiring channel 21.

[0050] In some embodiments, the outside of the electrical connection line 12 is wrapped or wrapped with a flame-retardant and heat-resistant fabric (not shown) to enhance the fire and heat insulation protection of the electrical connection line 12, which helps to prevent fire or high temperature from spreading along the electrical connection line 12 to the chip module 11 and damaging the chip module 11.

[0051] See Figure 4 In some embodiments, the operating parameter recorder 100 further includes a bundling member 30. The bundling member 30 is tied to the flame-retardant and heat-resistant member 20 to keep the flame-retardant and heat-resistant member 20 in a wound state.

[0052] The binding member 30 keeps the flame-retardant and heat-insulating member 20 in a wound state so that the flame-retardant and heat-insulating member 20 can continuously provide fireproof and heat-insulating protection, thereby improving the effect of dual protection for the chip module 11.

[0053] In some embodiments, the binding member 30 is configured as a rope-like structure made of flame-retardant and heat-resistant fibers and is bound to the outside of the flame-retardant and heat-resistant member 20. Exemplarily, the flame-retardant and heat-resistant fibers may be aluminum silicate or basalt.

[0054] The rope-like structure allows the bundle 30 to be fixed by binding, which on the one hand reduces the difficulty of setting up the bundle 30 and makes it easier to assemble the bundle 30; on the other hand, it allows the bundle 30 to adjust the thickness of the binding to accommodate flame-retardant and heat-resistant components 20 with different outer diameters.

[0055] In some embodiments, the binding member 30 is configured as a hoop structure made of metal material and is bound to the outside of the flame-retardant and heat-insulating member 20.

[0056] The hoop structure keeps the size of the bundle 30 relatively fixed and has good resistance to deformation, so that the bundle 30 can be stably fixed on the outside of the flame-retardant and heat-insulating component 20, which helps to reduce the possibility of the flame-retardant and heat-insulating component 20 falling off, thus maintaining the fireproof and heat-insulating effect.

[0057] Understandably, in some embodiments, the overlapping portions of the flame-retardant and heat-resistant components 20 are bonded together with fire-resistant and high-temperature resistant adhesive, which makes it easier to keep the flame-retardant and heat-resistant components 20 in a wound state, thereby making it easier for the binding component 30 to bind the flame-retardant and heat-resistant components 20 and reducing assembly difficulty.

[0058] See Figure 5 In some embodiments, the flame-retardant and heat-resistant component 20 includes a first wrapping component 22 and a second wrapping component 23. The first wrapping component 22 is wound around the outside of the chip module 11. The second wrapping component 23 is wound around the outside of the first wrapping component 22.

[0059] The first wrapping element 22 and the second wrapping element 23 wrap the chip module 11 from the inside out, so that the outer side of the chip module 11 has a multi-layer structure for fireproofing and heat insulation. Furthermore, the first wrapping element 22 and the second wrapping element 23 are independently wound, which helps to prevent fire or high temperature from entering the chip module 11 through the winding gap of the flame-retardant and heat-insulating element 20, thereby improving the fireproofing and heat insulation effect of the chip module 11.

[0060] It is understood that, in some embodiments, the overlapping portions of the first package 22 can be bonded together with a fire-resistant and high-temperature resistant adhesive. It is understood that, in some embodiments, the overlapping portions of the second package 23 can be bonded together with a fire-resistant and high-temperature resistant adhesive. It is understood that, in some embodiments, the overlapping portions between the first package 22 and the second package 23 can be bonded together with a fire-resistant and high-temperature resistant adhesive.

[0061] In some embodiments, the axis around which the first package 22 is wound intersects at least partially with the axis around which the second package 23 is wound.

[0062] The first package 22 and the second package 23 are wound around different axes. The second package 23 can wrap around the side of the first package 22, thereby improving the protective sealing of the flame-retardant and heat-insulating component 20 and enhancing the fireproof and heat-insulating effect.

[0063] Understandably, in some embodiments, the axis corresponding to the winding of the first package 22 is perpendicular to the axis corresponding to the winding of the second package 23, so that the first package 22 and the second package 23 can block each other's winding sides.

[0064] In some embodiments, the second package 23 wraps around the first package 22 to keep the first package 22 in a wound state. The binding member 30 is secured to the second package 23 to keep the second package 23 in a wound state.

[0065] The first package 22 is secured by the second package 23, which eliminates the need for the binding member 30 to secure the first package 22. This reduces the number of binding members 30 required and lowers production costs.

[0066] In some embodiments, a portion of the binding member 30 is disposed on the first package 22 to maintain the first package 22 in a wound state. A portion of the binding member 30 is disposed on the second package 23 (not shown) to maintain the second package 23 in a wound state.

[0067] After the first package 22 is wound around the outside of the chip module 11, it is fixed by the binding member 30, and then the second package 23 is wound around the outside of the first package 22. The shape and structure of the first package 22 are relatively fixed, which facilitates the second package 23 to be wound and wrapped, and facilitates the assembly of the housing assembly.

[0068] In some embodiments, the flame-retardant and heat-resistant component 20 is wound to form a flame-retardant and heat-resistant cavity 24. The chip module 11 is located inside the flame-retardant and heat-resistant cavity 24. Waterproof adhesive 111 is poured into the flame-retardant and heat-resistant cavity 24 to bond the chip module 11 and the flame-retardant and heat-resistant component 20.

[0069] Waterproof adhesive 111 is injected into the flame-retardant and heat-resistant cavity 24 to increase the sealing between the flame-retardant and heat-resistant component 20 and the chip module 11, thereby improving the waterproof effect. Furthermore, the chip module 11 is bonded and fixed to the flame-retardant and heat-resistant component 20 by the waterproof adhesive 111, which helps to reduce the shaking of the electrical connection wire 12 to avoid affecting the structure at the wire outlet channel 21, thereby maintaining the fireproof, heat-insulating and waterproof effect of the housing assembly at the wire outlet channel 21.

[0070] In some embodiments, the operating parameter recorder 100 further includes a flame-retardant and heat-resistant plug 40 and a waterproof plug 50. Both the flame-retardant and heat-resistant plug 40 and the waterproof plug 50 are located in the cable outlet channel 21. The electrical connection cable 12 passes through the flame-retardant and heat-resistant plug 40 and the waterproof plug 50 and extends to the outside of the flame-retardant and heat-resistant component 20. The flame-retardant and heat-resistant plug 40 is closer to the outside of the flame-retardant and heat-resistant component 20 than the waterproof plug 50.

[0071] By incorporating a flame-retardant and heat-resistant plug 40 and a waterproof plug 50, the waterproofing, heat insulation, and waterproofing effects at the cable outlet channel 21 are enhanced. Furthermore, with the flame-retardant and heat-resistant plug 40 on the outside and the waterproof plug 50 on the inside, the waterproof plug 50 is prevented from failing due to fire or high temperatures, thus maintaining its waterproofing effect.

[0072] Understandably, in some embodiments, the flame-retardant and heat-resistant plug 40 and the waterproof plug 50 are bonded to the outlet channel 21 with fire-resistant and high-temperature resistant adhesive to improve the stability of the flame-retardant and heat-resistant plug 40 and the waterproof plug 50, which is beneficial to maintaining the fireproof, heat-insulating and waterproof effect of the outlet channel 21.

[0073] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
