Moreover, the bag opening member can fix the fireproof heat-resistant plug to the bag opening while closing the bag opening, so as to maintain the fireproof heat-insulation effect of the fireproof heat-resistant plug at the bag opening.

[0010] In some embodiments of the present application, the joint between the fireproof heat-resistant plug and the fireproof bag is glued.

[0011] The fireproof heat-resistant plug is glued to the bag opening, which improves the sealing performance at the bag opening, thereby improving the fireproof heat-insulation effect at the bag opening.

[0012] In some embodiments of the present application, a rope buckle is arranged outside the fireproof bag. The rope buckle is configured to be fixed to the structure of the energy storage device.

[0013] The rope buckle can be hung or sleeved on the structure inside the energy storage device, which facilitates the assembly of the event data recorder in the device shell of the energy storage device.

[0018] In some embodiments of the present application, the bag opening member is a linear structure. The bag opening member is sewn to the bag opening to close the bag opening.

[0019] The linear structure of the bag opening member is directly sewn to the bag opening, which facilitates the reduction of the operation difficulty of closing the bag opening.

[0020] In some embodiments of the present application, the bag opening member is a hoop structure. The bag opening member is hooped to the bag opening to close the bag opening.

[0021] The hoop structure of the bag opening member is hooped to the bag opening, which improves the stability of the bag opening member fixed to the bag opening, thereby improving the stability of the closed bag opening to maintain the fireproof heat-insulation effect.

[0022] In some embodiments of the present application, the mouth binding member is a rope structure. The fireproof bag has a mouth binding channel at the bag mouth. The mouth binding channel has two openings. The mouth binding member is wound around the mouth binding channel at least once, and the two ends of the mouth binding member extend out of the two openings. The part of the mouth binding member outside the mouth binding channel is knotted to close the bag mouth.

[0023] After the rope structure mouth binding member passes through the mouth binding channel and is wound around the bag mouth at least once, the mouth binding member can be contracted by pulling the parts of the mouth binding member extending out of the two openings in opposite directions, thereby closing the bag mouth. The mouth binding member is maintained in the state of closing the bag mouth by knotting, thereby maintaining the fireproof and heat insulation effect.

And the event data recording piece is protected by the form of the fireproof bag body, which is light in structure and is beneficial to reduce the assembly difficulty of the event data recording piece.

[0042] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0043] Referring to Figures 1 to 3 An embodiment of the present application provides an event data recorder 100 and an energy storage device 200.

[0044] 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 event data recorder 100 is used to record the operation data of the energy storage device 200.

[0045] 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.

[0046] In some embodiments, the energy storage device 200 further includes a power conversion module (not shown in the figure).

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.

[0047] 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.

[0048] Referring to Figure 3 and Figure 4 In some embodiments, the energy storage device 200 further comprises an event data recorder 100. The event data recorder 100 is disposed in the device housing 201 and connected with the battery management device 203. For example, the event data recorder 100 and the battery management device 203 are both disposed in the housing of the battery module 202, and the event data recorder 100 is located beside the battery cell of the battery module 202 and avoids the spray valve path of the battery cell, wherein, Figure 3 The structure indicated by the reference sign of the battery module 202 in the figure is the battery cell of the battery module 202.

[0049] Referring to Figures 3 to 5 In some embodiments, the event data recorder 100 comprises an event data recording piece 10. The event data recording piece 10 comprises a chip module 11 and an electric connecting wire 12. The electric connecting wire 12 connects the chip module 11 and the battery management device 203. For example, the chip module 11 is a circuit board with data storage function.

[0050] The chip module 11 is connected with the battery management device 203 of the energy storage device 200 through the electric connecting wire 12 to record the operation data of the energy storage device 200, in particular the operation data of the battery module 202 and the battery management device 203.

[0051] Referring to Figure 5 In some embodiments, the event data recorder 100 further comprises a fireproof bag body 20, a mouth binding piece 30 and a heat insulation filler 40. The fireproof bag body 20 is configured to be flexible. The fireproof bag body 20 has a bag mouth 21. The bag mouth 21 communicates the inside and outside of the fireproof bag body 20. The mouth binding piece 30 is disposed in the fireproof bag body 20 and is configured to be able to close the bag mouth 21. The chip module 11 is disposed in the heat insulation filler 40. The outer side of the chip module 11 is coated with waterproof glue 111. The electric connecting wire 12 extends out of the fireproof bag body 20 through the bag mouth 21.

[0052] The chip module 11 is coated with waterproof glue 111 to prevent the chip module 11 from being contacted by fire extinguishing liquid. After the heat insulation filler 40 is wrapped around the chip module 11, the chip module 11 and the heat insulation filler 40 are loaded into the fireproof bag body 20, and the bag opening 21 is bundled by the bundling member 30. The fireproof bag body 20 can block the fire, and the heat insulation filler 40 can block the heat from entering the inside. On the one hand, it is beneficial to avoid damage to the chip module 11 caused by fire or high temperature, and on the other hand, it can reduce the influence of fire or high temperature on the waterproof effect of the waterproof glue 111, so as to maintain the waterproof effect of the waterproof glue 111, thereby double protecting the chip module 11, so that the chip module 11 can restore the operation data of the energy storage device 200, thereby facilitating the review of the accident cause. Moreover, the heat insulation filler 40 separates the chip module 11 and the fireproof bag body 20, and the fire or high temperature needs to pass through layer by layer to reach the chip module 11, thereby increasing the difficulty of damage to the chip module 11 caused by the fire or high temperature.

[0053] At the same time, the event data recorder 10 is protected by the form of the fireproof bag body 20, which is light in structure and beneficial to reduce the assembly difficulty of the event data recorder 10.

[0054] In some embodiments, the fireproof bag body 20 is an aluminum silicate cloth bag. The cloth bag made of aluminum silicate material is used as the fireproof bag body 20, which can not only block fire but also insulate heat, thereby improving the fireproof and heat insulation protection of the chip module 11. The fireproof bag body 20 is made of aluminum silicate material, so that the fireproof bag body 20 has the properties of high melting point and low thermal conductivity, thereby maintaining high stability under fire or high temperature and reducing the heat transferred inward.

[0055] Referring to Figure 4 and Figure 5 In some embodiments, a rope buckle (not shown in the figure) is arranged on the outside of the fireproof bag body 20. The rope buckle is configured to be fixed to the structure of the energy storage device 200.

[0056] The rope buckle can be hung or sleeved on the structure in the energy storage device 200, thereby facilitating the assembly of the event data recorder 100 in the device shell 201 of the energy storage device 200.

[0057] For example, the rope buckle can be hung on the hook-shaped structure in the device shell 201 or constrained by the protruding structure in the device shell 201.

[0058] In some embodiments, the bundling member 30 is made of non-flammable materials such as aluminum silicate material and metal material.

[0059] In some embodiments, the bundling member 30 is a linear structure. The bundling member 30 is sewn on the bag opening 21 to close the bag opening 21. Directly sewing the linear structure of the bundling member 30 on the bag opening 21 is beneficial to reduce the operation difficulty of closing the bag opening 21.

[0060] In some embodiments, the mouth closing member 30 is a hoop structure. The hoop structure of the mouth closing member 30 is hooped on the bag opening 21 to close the bag opening 21. Hooping the hoop structure of the mouth closing member 30 on the bag opening 21 improves the stability of the mouth closing member 30 fixed to the bag opening 21, thereby improving the stability of the closed bag opening 21 to maintain the fireproof and heat insulation effect.

[0061] Referring to Figure 4 and Figure 6 In some embodiments, the mouth closing member 30 is a rope structure. The bag opening 21 of the fireproof bag body 20 is provided with a mouth closing channel 22. The mouth closing channel 22 is arranged around or partially around the bag opening 21. The mouth closing channel 22 has two openings 221. The mouth closing member 30 is wound at least one turn around the mouth closing channel 22, and the two ends of the mouth closing member 30 extend out of the different openings 221. The part of the mouth closing member 30 outside the mouth closing channel 22 is knotted to close the bag opening 21.

[0062] After the rope structure of the mouth closing member 30 passes through the mouth closing channel 22 and is wound at least one turn around the bag opening 21, by pulling the part of the mouth closing member 30 extending out of the two openings 221 in the opposite direction, the mouth closing member 30 can be made to shrink in diameter, thereby closing the bag opening 21. By knotting the mouth closing member 30 to maintain the state of the bag opening 21 being closed by the shrinking in diameter, the fireproof and heat insulation effect is maintained.

[0063] Referring to Figure 5 In some embodiments, the heat insulation filler 40 is fireproof foam. Using fireproof foam as the heat insulation filler 40 can not only block fire, but also insulate heat, thereby improving the fireproof and heat insulation protection of the chip module 11. The heat insulation filler 40 is made of fireproof foam, so that the heat insulation filler 40 has the performance of low thermal conductivity and produces non-flammable substances after burning, thereby delaying combustion and blocking heat.

[0064] In some embodiments, the chip module 11 is fixed in the heat insulation filler 40 by the waterproof glue 111, which facilitates the assembly of the chip module 11 and the heat insulation filler 40 into the fireproof bag body 20.

[0065] In some embodiments, the heat insulation filler 40 fills the fireproof bag body 20 to increase the path of fire or high temperature from outside the fireproof bag body 20 to the chip module 11, thereby increasing the difficulty of damaging the chip module 11 and improving the fireproof and heat insulation effect. Here, full can be understood as, under the support of the heat insulation filler 40, the shape of the fireproof bag body 20 is in the shape of the maximum volume that can be reached in the state of the bag opening 21 being closed by the mouth closing member 30.

[0066] In some embodiments, the event data recorder 100 further comprises a fireproof heat-resistant cloth (not shown in the figure). The fireproof heat-resistant cloth wraps the electric connecting wire 12 at least at the portion outside the fireproof bag body 20. By protecting the electric connecting wire 12 from fire and heat through the fireproof heat-resistant cloth, it is beneficial to avoid the fire or high temperature from spreading along the electric connecting wire 12 to damage the chip module 11. Exemplarily, the fireproof heat-resistant cloth is made of aluminum silicate material.

[0067] It can be understood that, in some embodiments, the electric connecting wire 12 is entirely wrapped with the fireproof heat-resistant cloth, which is beneficial to avoid the partial structure of the electric connecting wire 12 from being exposed to the fire or high temperature environment due to the movement of the electric connecting wire 12 relative to the bag opening 21.

[0068] Referring to Figure 4 and Figure 5 In some embodiments, the event data recorder 100 further comprises a fireproof heat-resistant plug 50. The fireproof heat-resistant plug 50 is arranged at the bag opening 21. The bag opening limiting member 30 limits the fireproof heat-resistant plug 50 so as to fix the fireproof heat-resistant plug 50 at the bag opening 21.

[0069] By arranging the fireproof heat-resistant plug 50, the fireproof and heat insulation effect at the bag opening 21 is improved, which is beneficial to avoid the fire or high temperature from entering the inside of the fireproof bag body 20 through the bag opening 21 to damage the chip module 11. Moreover, the bag opening limiting member 30 can fix the fireproof heat-resistant plug 50 to the bag opening 21 when closing the bag opening 21, so as to maintain the fireproof and heat insulation effect of the fireproof heat-resistant plug 50 at the bag opening 21.

[0070] In some embodiments, the joint between the fireproof heat-resistant plug 50 and the fireproof bag body 20 is bonded by fireproof and heat-resistant adhesive.

[0071] The fireproof heat-resistant plug 50 is bonded to the bag opening 21, which improves the sealing of the bag opening 21, thereby improving the fireproof and heat insulation effect at the bag opening 21.

[0072] 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 as long as the above embodiments are within the spirit and scope of the present application, any suitable modification and change of the above embodiments are within the disclosure range of the present application.
