The data storage chip in the device may fail under the dual influence of fire and fire extinguishing liquid, making it impossible to restore the device operation data before the thermal runaway, which is not conducive to the subsequent analysis of the accident. CONTENT OF THE UTILITY MODEL

The chip module is coated with waterproof glue to prevent the fire extinguishing liquid from contacting the chip module. The chip module is wrapped in the aluminum silicate heat insulation piece and then loaded into the mica shell to prevent the fire and heat from spreading to the place where the chip module is located. On the one hand, it is beneficial to avoid damage to the chip module caused by fire or high temperature. On the other hand, it can reduce the influence of fire or high temperature on the waterproof glue to maintain the waterproof effect of the waterproof glue, so that the chip module is double-protected.

[0016] In some embodiments of the present application, the joint between the mica shell body and the mica shell cover is glued.

[0017] The joint between the mica shell body and the mica shell cover is glued to improve the sealing between the mica shell body and the mica shell cover, thereby improving the fireproof, heat insulation, and waterproof effects of the mica shell.

[0018] In some embodiments of the present application, the information storage device further includes a fireproof and heat resistant plug. The fireproof and heat resistant plug is arranged in the wire outlet passage. The electric connection line passes through the fireproof and heat resistant plug and extends to the outside of the mica shell.

[0019] The fireproof heat resistance plug can fill the gap between the electric connecting wire and the mica shell, so as to improve the fireproof and heat insulation effect of the outlet channel, and avoid the fire or high temperature from entering the mica shell through the outlet channel to damage the chip module.

[0021] The joint between the fireproof heat resistance plug and the mica shell is glued to improve the sealing of the outlet channel, so as to improve the fireproof, heat insulation and waterproof effect of the mica shell. The electric connecting wire can be relatively fixed at the outlet channel, which is conducive to reducing the shaking of the electric connecting wire to avoid affecting the protection effect of the outlet channel, so as to maintain the fireproof, heat insulation and waterproof effect of the mica shell at the outlet channel.

[0036] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments.

[0037] 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 to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0038] In some cases, the energy storage device may have a thermal runaway phenomenon, causing a fire and explosion in the device. The data storage chip in the device may fail under the dual influence of fire and fire extinguishing liquid, making it impossible to restore the device operation data before the thermal runaway, which is not conducive to the subsequent analysis of the accident cause.

[0039] An information storage device is provided by an embodiment of the present application and applied to an energy storage device. The information storage device comprises a mica shell, an aluminum silicate thermal insulation part, and an exceptional backtracking part. The mica shell is provided with an outlet passage. The outlet passage communicates the inside and outside of the mica shell. The aluminum silicate thermal insulation part is filled in the mica shell. The exceptional backtracking part comprises a chip module and an electric connection wire. The chip module is arranged in the mica shell and wrapped in the aluminum silicate thermal insulation part. The outer side of the chip module is coated with waterproof glue. The electric connection wire is connected with the chip module. The electric connection wire extends out of the mica shell through the outlet passage.

[0040] The chip module is connected with the battery management device of the energy storage device through an electric connection line to record the operation data of the energy storage device. The chip module is coated with waterproof glue to prevent the chip module from being contacted by fire extinguishing liquid. The chip module is wrapped with an aluminum silicate thermal insulation piece and then is loaded into a mica shell to prevent the fire and heat from spreading to the chip module, which is beneficial to avoiding damage of the chip module caused by the fire or high temperature and reducing the influence of the fire or high temperature on the waterproof glue to maintain the waterproof effect of the waterproof glue, so that the chip module is double-protected.

[0041] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments can be combined with each other without conflict.

[0042] Referring to Figures 1 to 3 An embodiment of the present application provides an information storage device 100 and an energy storage device 200. In some embodiments, the energy storage device 200 has the functions of storing and discharging electricity, and is used for home power backup, production unit power backup, outdoor work, outdoor entertainment, etc. The information storage device 100 is used to record the operation data of the energy storage device 200.

[0043] In some embodiments, the energy storage device 200 includes a device shell 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 arranged in the device shell 201. For example, the battery management device 203 can be a BMS (Battery Management System) board.

[0044] In some embodiments, the energy storage device 200 further includes a power conversion module (not shown in the figure). The power conversion module is electrically connected with the battery module 202, and the power conversion module is used to realize AC / DC conversion control of the output current of the battery module 202. The energy storage device 200 provided with the power conversion module can be a small portable power supply, a household energy storage power supply, an industrial and commercial energy storage power supply or a container type energy storage power supply, etc.

[0045] In some embodiments, the power conversion module can be omitted. The energy storage device 200 without the power conversion module can be used independently. The energy storage device 200 without the power conversion module can usually only output DC power. When the energy storage device 200 without the power conversion module is used independently, it can be used in coordination with the energy storage device 200 provided with the power conversion module as a power supply system providing additional battery capacity.

[0046] Referring to Figure 3 and Figure 4In some embodiments, the energy storage device 200 further comprises an information storage device 100. The information storage device 100 is arranged in the device housing 201 and connected with the battery management device 203. For example, the information storage device 100 and the battery management device 203 are arranged in the housing of the battery module 202, the information storage device 100 is located beside the battery cell of the battery module 202 and avoids the spray path of the battery cell, wherein, Figure 3 The structure indicated by the reference sign of the battery module 202 is the battery cell of the battery module 202.

[0047] Referring to Figures 3 to 5 In some embodiments, the information storage device 100 comprises a mica shell 10, an aluminum silicate thermal insulation 20 and an abnormality backtracking device 30. The mica shell 10 is provided with a wire outlet passage 121. The wire outlet passage 121 communicates the inside and outside of the mica shell 10. The aluminum silicate thermal insulation 20 is filled in the mica shell 10. The abnormality backtracking device 30 comprises a chip module 31 and an electric connection wire 32. The chip module 31 is arranged in the mica shell 10 and wrapped in the aluminum silicate thermal insulation 20. The chip module 31 is coated with waterproof glue outside. The electric connection wire 32 is connected with the chip module 31. The electric connection wire 32 extends to the outside of the mica shell 10 through the wire outlet passage 121. For example, the waterproof glue can be silicone waterproof glue.

[0048] The chip module 31 is connected with the battery management device 203 of the energy storage device 200 through the electric connection wire 32 to record the operation data of the energy storage device 200, especially the operation data of the battery module 202 and the battery management device 203. The chip module 31 is coated with waterproof glue to prevent the fire extinguishing liquid from contacting the chip module 31. The chip module 31 is wrapped in the aluminum silicate thermal insulation 20 and then arranged in the mica shell 10 to prevent the fire and heat from spreading to the place where the chip module 31 is located. On the one hand, it is beneficial to avoid damage to the chip module 31 caused by fire or high temperature. On the other hand, it can reduce the influence of fire or high temperature on the waterproof glue to maintain the waterproof effect of the waterproof glue, so that the chip module 31 is double protected.

[0049] In some embodiments, the mica shell 10 is made of mica combined with other materials, and the mica has a layered silicate structure with large gaps between layers, which can prevent or slow down the transmission of fire and high temperature to the inside. Secondly, mica has high thermal stability and can withstand high temperature environment without decomposition or deformation, thereby continuing to play a fireproof and heat insulation role. Thirdly, mica has a certain water absorption, which can absorb the water produced in the fire process to reduce the temperature of the fire and slow down the spread of the fire. In addition, the surface crystal structure of mica changes constantly, and the electric charge also changes, which can absorb oxygen and reduce the supply of oxygen, thereby reducing the spread of the fire.

[0050] Meanwhile, the mica has good insulation, which is conducive to reducing the risk of circuit short circuit between the chip module 31 and the battery module 202, the battery management module or other electrical structures of the energy storage device 200, and helps the chip module 31 to store data normally.

[0051] In addition, the mica has good mechanical strength, is firm and durable, so that the mica shell 10 can withstand greater external force impact, and the mica has a low thermal expansion coefficient, so that the mica shell 10 maintains a stable size in fire and high temperature environment, which is conducive to preventing the aluminum silicate heat insulation piece 20 from being damaged, so that the aluminum silicate heat insulation piece 20 provides the expected fireproof and heat insulation effect, and is also conducive to preventing the chip module 31 from being damaged, so that the chip module 31 stores data normally.

[0052] Referring to Figures 4 to 6 In some embodiments, the mica shell 10 includes a mica shell body 11 and a mica shell cover 12. The mica shell body 11 or the mica shell cover 12 is provided with a wire outlet passage 121. The chip module 31 is arranged in the mica shell body 11. The mica shell cover 12 is arranged on the mica shell body 11, which is convenient to disassemble and assemble, and facilitates the chip module 31 and the aluminum silicate heat insulation piece 20 to be arranged in the mica shell 10.

[0053] In some embodiments, the mica shell 10 further includes a connecting piece (not shown in the figure). The connecting piece connects the mica shell body 11 and the mica shell cover 12. The mica shell cover 12 and the mica shell body 11 are fixed through the connecting piece, and the sealing between the mica shell cover 12 and the mica shell body 11 is improved, so as to improve the fireproof and heat insulation effect of the mica shell 10.

[0054] For example, the connecting piece is a bolt or screw structure, which is threadedly connected to the mica shell body 11 after penetrating through the mica shell cover 12, so that the connection between the mica shell body 11 and the mica shell cover 12 is tight; or the connecting piece is a buckle structure, which buckles the mica shell cover 12 to the mica shell body 11 through clamping cooperation, so as to facilitate the mutual disassembly and assembly of the mica shell body 11 and the mica shell cover 12.

[0055] In some embodiments, the joint between the mica shell body 11 and the mica shell cover 12 is glued with fireproof and high-temperature resistant glue, so as to improve the sealing between the mica shell body 11 and the mica shell cover 12, thereby improving the fireproof, heat insulation and waterproof effects of the mica shell 10.

[0056] In some embodiments, the aluminum silicate heat insulation piece 20 is made of aluminum silicate material combined with other materials. The aluminum silicate material makes the aluminum silicate heat insulation piece 20 have the performance of high melting point and low thermal conductivity, so that it can still maintain high stability under fire or high temperature, and can reduce the heat transferred inward. For example, the aluminum silicate heat insulation piece 20 can be made of aluminum silicate material combined with basalt fiber.

[0057] Referring to Figure 4 andFigure 7 In some embodiments, the aluminum silicate heat insulation piece 20 is an aluminum silicate cloth 21 formed by aluminum silicate fibers. The aluminum silicate cloth 21 is wrapped around the chip module 31.

[0058] The aluminum silicate heat insulation piece 20 protects the chip module 31 in the form of the aluminum silicate cloth 21 wrapped around the chip module 31, facilitates quick assembly of a protection structure outside the chip module 31, and can adaptively adjust the size of the aluminum silicate cloth 21 according to the size of the chip module 31 and the mica shell 10, thereby reducing the difficulty of preparing the aluminum silicate heat insulation piece 20.

[0059] It can be understood that, in some embodiments, the aluminum silicate cloth 21 can be made of aluminum silicate fibers by weaving, or can be made of aluminum silicate fibers by non-woven.

[0060] It can be understood that, in some embodiments, gaps or areas can be left during winding of the aluminum silicate cloth 21 to allow the power connection line 32 to extend out without being tightly shielded outside the chip module 31.

[0061] In some embodiments, the information storage device 100 further includes a fixing piece 40. The fixing piece 40 is arranged on the aluminum silicate cloth 21 to fix the aluminum silicate cloth 21 wrapped around the chip module 31.

[0062] By arranging the fixing piece 40, the shape of the aluminum silicate cloth 21 wrapped around the chip module 31 is fixed, which can prevent the aluminum silicate cloth 21 from being scattered when the chip module 31 is loaded into the mica shell 10, thereby reducing the assembly difficulty and improving the assembly efficiency.

[0063] It can be understood that, in some embodiments, the fixing piece 40 is a fireproof and high-temperature-resistant glue, so that the overlapping parts of the aluminum silicate cloth 21 are bonded to each other to be fixed, which is conducive to reducing the difficulty of fixing the aluminum silicate cloth 21.

[0064] It can be understood that, in some embodiments, the fixing piece 40 is in a rope structure and is tied outside the aluminum silicate cloth 21. On the one hand, the fixing piece 40 has a relatively low assembly difficulty, and on the other hand, the fixing piece 40 can adaptively adjust the thickness of the tie to adapt to aluminum silicate cloths 21 of different outer diameters.

[0065] It can be understood that, in some embodiments, the fixing piece 40 is in a hoop structure and is tied outside the aluminum silicate cloth 21. The hoop structure makes the fixing piece 40 have a relatively fixed size and good deformation resistance, so that the fixing piece 40 can be stably fixed outside the aluminum silicate cloth 21, which is conducive to reducing the possibility of the aluminum silicate cloth 21 being scattered to maintain the fireproof and heat insulation effect.

[0066] Referring to Figures 4 to 6In some embodiments, the aluminum silicate thermal insulation 20 is aluminum silicate fiber. The aluminum silicate fiber is filled between the chip module 31 and the mica shell 10. The aluminum silicate thermal insulation 20 in the form of aluminum silicate fiber filled between the chip module 31 and the mica shell 10 protects the chip module 31, and even if the size of the chip module 31 and the mica shell 10 changes, a complete protective layer can be formed outside the chip module 31, and the size range of the information storage device 100 to which the aluminum silicate thermal insulation 20 is applicable is improved.

[0067] In some embodiments, the aluminum silicate thermal insulation 20 is in the form of directly filling aluminum silicate fiber instead of forming aluminum silicate cloth 21, which on the one hand helps to reduce the material cost of the aluminum silicate thermal insulation 20, and on the other hand can fill the space between the chip module 31 and the mica shell 10 as much as possible, thereby improving the fireproof and thermal insulation effect.

[0068] It can be understood that in some embodiments, the aluminum silicate fiber can be in the form of aerogel, which helps to improve the thermal insulation effect of the aluminum silicate thermal insulation 20 and reduce the weight of the aluminum silicate thermal insulation 20.

[0069] In some embodiments, the aluminum silicate thermal insulation 20 is an aluminum silicate shell. The chip module 31 is arranged in the aluminum silicate shell. The electrical connection line 32 passes through the aluminum silicate shell. The aluminum silicate shell and the mica shell 10 are at least partially spaced apart to form a separation space.

[0070] The aluminum silicate thermal insulation 20 in the form of an aluminum silicate shell protects the chip module 31, is convenient to disassemble and assemble, facilitates the chip module 31 to be arranged in the mica shell 10 together with the aluminum silicate thermal insulation 20, and facilitates the formation of a separation space between the aluminum silicate shell and the mica shell 10, reduces the contact between the aluminum silicate shell and the mica shell 10, increases the difficulty of heat transfer from the mica shell 10 to the aluminum silicate shell, and improves the fireproof and thermal insulation effect of the chip module 31.

[0071] It can be understood that in some embodiments, the separation space is configured to form a negative pressure compared to the atmospheric pressure to improve the thermal insulation effect.

[0072] It can be understood that in some embodiments, the separation space is at least located on the path of the electrical connection line 32, which helps to block or alleviate the spread of fire and high temperature along the electrical connection line 32 to the chip module 31.

[0073] In some embodiments, the aluminum silicate shell includes an aluminum silicate shell body and an aluminum silicate shell cover (not shown in the figure). The chip module 31 is arranged in the aluminum silicate shell body. The aluminum silicate shell cover is arranged on the aluminum silicate shell body, which is convenient to disassemble and assemble, and facilitates the chip module 31 to be arranged in the aluminum silicate shell.

[0074] It can be understood that in some embodiments, the electric connecting wire 32 extends out of the mica shell 10 through the aluminum silicate shell cover and the mica shell cover 12. The mica shell cover 12 abuts against the aluminum silicate shell cover to make the aluminum silicate shell cover fit in the direction of the aluminum silicate shell body and form a separation space between the aluminum silicate shell cover and the mica shell cover 12. The mica shell cover 12 presses the aluminum silicate shell cover on the aluminum silicate shell body to improve the sealing effect between the aluminum silicate shell cover and the aluminum silicate shell body, thereby improving the fireproof, heatproof and waterproof effects of the aluminum silicate shell.

[0075] Referring to Figure 4 , Figure 5 and Figure 7 In some embodiments, the aluminum silicate heat insulation member 20 can simultaneously adopt multiple forms among the three forms of the aluminum silicate cloth 21, the aluminum silicate fiber and the aluminum silicate shell. For example, the aluminum silicate cloth 21 is wrapped outside the chip module 31, the aluminum silicate fiber is filled between the aluminum silicate cloth 21 and the chip module 31, and then they are all loaded into the aluminum silicate shell.

[0076] Referring to Figures 4 to 6 In some embodiments, the information storage device 100 further comprises a fireproof and heatproof plug 50. The fireproof and heatproof plug 50 is arranged at the wire outlet passage 121. The electric connecting wire 32 extends out of the mica shell 10 through the fireproof and heatproof plug 50.

[0077] The fireproof and heatproof plug 50 can fill the gap between the electric connecting wire 32 and the mica shell 10, thereby improving the fireproof and heatproof effects of the wire outlet passage 121, which is beneficial to avoid the fire or high temperature from entering the inside of the mica shell 10 through the wire outlet passage 121 to damage the chip module 31.

[0078] In some embodiments, the junction of the fireproof and heatproof plug 50 and the mica shell 10 is bonded by fireproof and heatproof glue. The junction of the fireproof and heatproof plug 50 and the electric connecting wire 32 is bonded by fireproof and heatproof glue.

[0079] The junction of the fireproof and heatproof plug 50 and the mica shell 10 is bonded to improve the sealing performance at the wire outlet passage 121, thereby improving the fireproof, heatproof and waterproof effects of the mica shell 10. In addition, the electric connecting wire 32 can be relatively fixed at the wire outlet passage 121, which is beneficial to reduce the shaking of the electric connecting wire 32 to avoid affecting the protection effect at the wire outlet passage 121, thereby maintaining the fireproof, heatproof and waterproof effects of the mica shell 10 at the wire outlet passage 121.

[0080] In addition, those skilled in the art should understand that the above embodiments are only used to illustrate the present application, but not as a limitation to the present application, and any appropriate changes and variations made to the above embodiments within the spirit and principles of the present application fall within the scope of the present application.
