[0046] The following will Figures 1 - 13 describe in detail the cover assembly 10, battery 100, energy storage device 1000, and electrical equipment 10000 according to the embodiments of the present utility model.

[0047] Referring to Figures 1 - 6 as shown, the cover assembly 10 according to the embodiment of the present utility model may include a cover body 1, a signal transmission antenna 4, and an antenna connection line 5.

[0048] Wherein, an antenna hole 11 and a connection hole 12 are provided on the cover body 1. One end of the antenna hole 11 penetrates to one side of the cover body 1, and one end of the connection hole 12 communicates with the antenna hole 11, and the other end of the connection hole 12 penetrates to the other side of the cover body 1.

[0049] Referring to Figures 4 - 6 as shown, the signal transmission antenna 4 is installed in the antenna hole 11. The upper end of the antenna connection line 5 passes through the connection hole 12 and is connected to the signal transmission antenna 4, and the lower end of the antenna connection line 5 extends to the lower side of the cover body 1. When the cover assembly 10 is applied to the battery 100, it is convenient for the antenna connection line 5 to be connected to other structures inside the battery 100 (such as the chip assembly 30 mentioned below).

[0050] In some embodiments, the cover body 1 may be a single-layer board.

[0051] In some embodiments, the cover body 1 may be a composite board. For example, the cover body 1 may include a cover plate 2 and an insulating plate 3. The insulating plate 3 is disposed on one side of the cover plate 2. One end of the antenna hole 11 penetrates to the side of the cover plate 2 facing away from the insulating plate 3, and the other end of the antenna hole 11 is separated from the side of the insulating plate 3 facing away from the cover plate 2. The connection hole 12 is provided on the insulating plate 3. One end of the connection hole 12 communicates with the antenna hole 11, and the other end of the connection hole 12 penetrates to the side of the insulating plate 3 facing away from the cover plate 2; the signal transmission antenna 4 is installed in the antenna hole 11, and one end of the antenna connection line 5 passes through the connection hole 12 and is connected to the signal transmission antenna 4, and the other end of the antenna connection line 5 extends to the side of the insulating plate 3 facing away from the cover plate 2.

[0052] Referring to Figures 1 - 3As shown, the cover plate body 1 includes a cover plate 2 and an insulating plate 3. The insulating plate 3 is disposed on the lower side of the cover plate 2. The cover plate body 1 is provided with an antenna hole 11 and a connection hole 12. The upper end of the antenna hole 11 penetrates through to the upper side surface of the cover plate 2, and the lower end of the antenna hole 11 is separated from the lower side surface of the insulating plate 3. The upper end of the connection hole 12 communicates with the antenna hole 11, and the lower end of the connection hole 12 penetrates through to the lower side surface of the insulating plate 3.

[0053] Referring to Figures 4 - 6 As shown, the signal transmission antenna 4 is installed in the antenna hole 11. The lower end of the antenna connection line 5 extends out to the lower side of the insulating plate 3. Since the lower end of the antenna hole 11 is separated from the lower side surface of the insulating plate 3, the signal transmission antenna 4 is isolated from the internal space of the battery 100 by at least a part of the insulating plate 3, preventing the electrolyte inside the battery 100 from corroding the signal transmission antenna 4.

[0054] Optionally, in some embodiments, the cover plate 2 is a metal plate, thereby making the cover plate assembly 10 have a relatively high strength. For example, the cover plate 2 can be an aluminum plate, a copper plate, a stainless steel plate, etc. The insulating plate 3 is a non-conductive plate. When the cover plate assembly 10 is applied to the battery 100, the insulating plate 3 can isolate the cover plate 2 on one side of the insulating plate 3 from the interior of the battery 100 on the other side of the insulating plate 3, preventing conduction between the electrolyte inside the battery 100 and the cover plate 2. Exemplarily, the insulating plate 3 can be a plastic material part, such as a polypropylene material part, and can also be a rubber material part or a silicone material part, etc. Optionally, the insulating plate 3 can be a spacer ring of the battery 100.

[0055] Optionally, both the antenna hole 11 and the connection hole 12 are straight holes extending along the thickness direction of the cover plate body 1. Thus, the processing of the antenna hole 11 and the connection hole 12 is relatively easy. In a plane perpendicular to the thickness direction of the cover plate body 1 (the thickness direction of the cover plate body 1 is the Figures 1 - 6 up and down direction in Figures 1 - 6 ), the connection hole 12 is located within the range of the antenna hole 11, so that in the thickness direction of the cover plate body 1, the connection hole 12 can communicate with the antenna hole 11, and the antenna connection line 5 in the connection hole 12 can be connected to the signal transmission antenna 4 in the antenna hole 11. As

[0056] shown, the connection hole 12 is located directly below the antenna hole 11, and the combined hole of the connection hole 12 and the antenna hole 11 penetrates through the cover plate body 1 along the thickness direction of the cover plate body 1.

[0056] Optionally, the signal transmission antenna 4 is mainly based on semiconductor silicon and is modified with one or more of various materials such as copper, silver, and aluminum. Optionally, the antenna connection line 5 can be one of metal copper, silver, or optical fiber.

[0057] Optionally, the shape of the antenna hole 11 can be a cuboid, a cube, a polyhedron, etc.

[0058] The depth of the antenna hole 11 is H1, and the thickness of the cover plate 2 is H2. In some embodiments, for example Figure 1 as shown, the depth of the antenna hole 11 is equal to the thickness of the cover plate 2, that is, H1 = H2. At this time, the depth of the connection hole 12 is equal to the thickness of the insulating plate 3; in other embodiments, for example Figure 2 as shown, the depth of the antenna hole 11 is less than the thickness of the cover plate 2, that is, H1 < H2. At this time, the depth of the connection hole 12 is greater than the thickness of the insulating plate 3, and a part of the connection hole 12 is located inside the insulating plate 3 and the other part is located inside the cover plate 2; in still other embodiments, for example Figure 3 as shown, the depth of the antenna hole 11 is greater than the thickness of the cover plate 2, that is, H1 > H2. That is to say, a part of the antenna hole 11 is located inside the cover plate 2 and the other part is located inside the insulating plate 3, and H1 < H2 + H3. At this time, the depth of the connection hole 12 is less than the thickness of the insulating plate 3.

[0059] It can be understood that the "thickness of the cover plate body 1", "thickness of the cover plate 2", "thickness of the insulating plate 3", "depth of the antenna hole 11", and "depth of the connection hole 1" mentioned in the present invention all refer to Figures 1 - 6 the dimension in the up and down direction in

[0060] In some embodiments of the present invention, the cover plate assembly 10 can be a positive cover plate assembly 10a. The positive cover plate assembly 10a is provided with a liquid injection hole 212.

[0062] In some embodiments of the present invention, the cover plate assembly 10 can be a total cover plate assembly 10c. The total cover plate assembly 10c is provided with a liquid injection hole 212 and an explosion-proof valve hole 222. The antenna hole 11 can also be arranged on the total cover plate assembly 10c, and the setting position on the total cover plate assembly 10c is between the liquid injection hole 212 and the explosion-proof valve hole 222, such as Figure 6 shown.

[0063] According to the cover assembly 10 of the embodiment of the present invention, a signal transmission antenna 4 is set in the antenna hole 11, and the signal transmission antenna 4 is connected to the inside of the battery 100 on one side of the cover assembly 10 through the antenna connecting line 5, so that the signal of the chip 301 inside the battery 100 can be effectively transmitted to the outside of the battery 100 through the signal transmission antenna 4, which can effectively improve the signal transmission capability, thereby achieving the purpose of effectively monitoring the internal signal of the battery 100 outside the battery 100, which is beneficial to improving the safety of the battery 100.

[0064] In some embodiments of the present invention, the cover assembly 10 further includes a sealing plate 6, which is a non-metallic plate and blocks the end of the antenna hole 11 away from the connection hole 12. Figures 4 - 6 As shown, the sealing plate 6 blocks the upper end of the antenna hole 11.

[0065] In some embodiments of the present invention, one of the cover body 1 and the sealing plate 6 is provided with a buckle, and the other is provided with a slot. The buckle is adapted to engage with the slot, thereby securing the sealing plate 6 to the cover body 1. The sealing plate 6 can be secured to the cover body 1 by snapping onto the cover body 1. Optionally, multiple slots are designed around the antenna hole 11 on the cover body 1, and the sealing plate 6 has multiple buckles. The buckles engage with the slots one by one, thereby achieving a sealed, snap-fit fixation of the non-metallic sealing plate 6. The number of slots can be two, three, four, five, etc.

[0066] When the cover body 1 includes the cover 2 and the insulating plate 3 , one of the cover 2 and the sealing plate 6 is provided with a buckle, and the other is provided with a slot, thereby the sealing plate 6 is fixedly mounted on the cover 2 .

[0067] Optionally, the sealing plate 6 is mainly made of a high molecular polymer material, such as polypropylene, polyethylene and the like.

[0068] In some embodiments of the present invention, the cover assembly 10 further includes a first sealing ring 7, which is disposed on the end of the signal transmission antenna 4 facing the antenna connection line 5. The first sealing ring 7 is in contact with the wall of the antenna hole 11. The first sealing ring 7 is provided with a sealing hole, and the antenna connection line 5 passes through the sealing hole and is in contact with the wall of the sealing hole. The first sealing ring 7 prevents the internal electrolyte from leaking from the connection hole 12 and the antenna hole 11. Figures 4 - 6 The antenna connecting line 5 is located below the signal transmission antenna 4 , and the first sealing ring 7 is arranged at the bottom end of the signal transmission antenna 4 .

By rationally utilizing the positions of the cover plate 2 and the insulating plate 3, the structure of the cover plate assembly 10 can be made more compact and convenient for production and processing.

[0082] In some embodiments of the present invention, the cover body 1 is provided with a positive electrode hole 211 for the positive electrode 40 to pass through and a negative electrode hole 221 for the negative electrode 50 to pass through.

The liquid injection hole 212, antenna hole 11, positive electrode post hole 211, negative electrode post hole 221, and explosion-proof valve hole 222 are arranged in sequence. Of course, in the main cover plate assembly 10c not shown in the figure, the antenna hole 11 can also be located near the explosion-proof valve hole 222. For example, the liquid injection hole 212, positive electrode post hole 211, negative electrode post hole 221, antenna hole 11, and explosion-proof valve hole 222 are arranged in sequence. By rationally utilizing the positions of the cover plate 2 and the insulating plate 3, the structure of the cover plate assembly 10 can be made more compact and convenient for production and processing.

[0083] It is understood that when the cover assembly 10 is applied to the battery 100, electrolyte can be injected into the battery 100 through the injection hole 212. An explosion-proof valve can be provided at the explosion-proof valve hole 222 to improve the safety of the battery 100.

[0084] Reference Figure 4 、 Figure 6 As shown, the positive electrode post 40 includes a positive electrode post body 401 and a positive electrode post lead-out tab 402. The positive electrode post body 401 passes through the positive electrode post hole 211, and the positive electrode post lead-out tab 402 is connected to the positive electrode post body 401. The positive electrode post lead-out tab 402 is located on the side of the insulating plate 3 facing away from the cover plate 2. The provision of the positive electrode post lead-out tab 402 facilitates connection between the electrode core 20 and the chip assembly 30 inside the battery 100 and the positive electrode post 40.

[0085] Reference Figures 5 - 6As shown, the negative electrode post 50 includes a negative electrode post body 501 and a negative electrode post lead-out tab 502. The negative electrode post body 501 passes through the negative electrode post hole 221, and the negative electrode post lead-out tab 502 is connected to the negative electrode post body 501. The negative electrode post lead-out tab 502 is located on the side of the insulating plate 3 facing away from the cover plate 2. The provision of the negative electrode post lead-out tab 502 facilitates the connection between the electrode core 20 and the chip assembly 30 inside the battery 100 and the negative electrode post 50.

[0086] Optionally, the number of signal transmission antennas 4 on each cover assembly 10 may be one or more.

[0087] Reference Figures 4 - 11 As shown, the battery 100 according to the embodiment of the second aspect of the present invention includes a pole, a shell body, a chip assembly 30 and the cover assembly 10 of the above embodiment, and the pole is arranged in the pole hole 23 on the cover assembly 10; at least one end of the shell body is an open end, and the cover assembly 10 is arranged at the open end. The cover assembly 10 and the shell body form a battery shell, and the cover assembly 10 and the shell body can form a closed space.

[0088] The chip assembly 30 includes a chip 301 and a pole connector. The chip 301 is embedded in the shell body and includes a circuit structure and a detection structure. The detection structure is electrically connected to the circuit structure. One end of the pole connector is electrically connected to the circuit structure, and the other end of the pole connector is suitable for connection to the corresponding pole. The antenna connection line 5 is suitable for connection to the pole connector. The signal collected by the chip 301 is transmitted to the outside of the battery 100 through the pole and the signal transmission antenna 4. The circuit structure and the pole of the battery 100 are electrically connected through the pole connector. That is to say, the battery 100 can power the detection structure, and then the battery 100 can power the chip assembly 30. The battery 100 and the chip assembly 30 form an integrated self-powered battery chip assembly, without the need to set up an external power supply to power the chip assembly 30, thereby improving the integration of the battery 100 and the chip assembly 30.

[0089] It should be further explained that the detection structure can be a temperature sensor and its associated connectors to detect the temperature of the battery 100; a stress detection device to detect the stress condition within the battery 100; or an air pressure detection device to detect the air pressure within the battery 100. This means that the detection structure within chip 301 can be replaced to meet different testing requirements, depending on the monitoring content and requirements. Therefore, the detection structure includes but is not limited to temperature sensors, stress detection devices, and air pressure detection devices.

[0090] In the related art, the detection device is located outside the battery 100. However, the detection device located outside detects the external state of the battery 100, and there is still a certain gap between the external state of the battery 100 and the internal state of the battery 100. Therefore, the detection device located outside the battery 100 reflects the internal state of the battery 100 with relatively low accuracy. In this application, the chip assembly 30 is arranged inside the battery case. The chip assembly 30 can monitor a single battery 100, can effectively monitor the temperature, air pressure and stress changes of the battery 100, can more accurately reflect the internal state of the battery 100, and can realize high-precision evaluation and safety warning of the working state and health state of the battery 100, thereby greatly improving the safety performance of the battery 100.

[0091] In some embodiments of the present utility model, the pole includes a positive pole 40 and a negative pole 50. At least one of the positive pole 40 and the negative pole 50 is arranged in the pole hole 23 on the cover plate assembly 10. The pole connector includes a positive member 302 and a negative member 303. One end of the positive member 302 is electrically connected to the circuit structure, and the other end of the positive member 302 is adapted to be connected to the positive pole 40. One end of the negative member 303 is electrically connected to the circuit structure, and the other end of the negative member 303 is adapted to be connected to the negative pole 50. The circuit structure and the pole of the battery 100 are electrically connected through the positive member 302 and the negative member 303. That is to say, the battery 100 can supply power to the detection structure, and further the battery 100 can supply power to the chip assembly 30.

[0092] The antenna connection line 5 is adapted to be connected to the positive member 302 or the negative member 303, and the antenna connection line 5 is also used to connect the signal transmission antenna 4 and the chip 301 inside the battery 100.

[0093] Optionally, the antenna connection line 5 and the positive member 302 can be connected by welding, and the antenna connection line 5 and the negative member 303 can be connected by welding. Thus, the connection method is simple and the connection firmness is relatively high. The welding method between the antenna connection line 5 and the positive member 302 and between the antenna connection line 5 and the negative member 303 can be one of brazing, laser welding and spot welding processes.

[0094] Figure 7 It is a connection schematic diagram of the chip assembly 30 inside the battery 100 and the signal transmission antenna 4 on the positive side. The chip assembly 30 inside the housing body is mainly composed of an integrated detection chip 301, a positive member 302 and a negative member 303. Combining Figure 4 and Figure 7, both ends of the housing body are open ends. One end of the housing body is the positive cover plate assembly 10a, and the other end is the second negative cover plate assembly 110b. A signal transmission antenna 4 is provided on the positive cover plate assembly 10a. The signal transmission antenna 4 is connected to the antenna connection line 5, and no signal transmission antenna 4 is provided on the second negative cover plate assembly 110b. The positive electrode member 302 of the chip assembly 30 is pulled to the positive electrode side to be connected to the antenna connection line 5 on the positive electrode side. After welding is completed, the connection part needs to be coated with an insulating and anti-corrosion film to prevent the welded part from being corroded by the electrolyte. Subsequently, the antenna connection line 5 is pulled together to the positive electrode post lead-out piece 402 on the positive cover plate assembly 10a for laser welding. The negative electrode member 303 of the chip assembly 30 is pulled to the negative electrode post lead-out piece 502 on the second negative cover plate assembly 110b for laser welding, so that the chip 301 can be self-powered by the electrode core 20 subsequently. Figure 7 The dotted line in it shows the signal transmission position.

[0095] Similarly, when the antenna hole 11 is on the negative electrode side, the connection schematic diagram of the chip assembly 30 inside the battery 100 and the signal transmission antenna 4 on the positive electrode side is as Figure 8 shown. Combining Figure 5 and Figure 8 , both ends of the housing body are open ends. One end of the housing body is the negative cover plate assembly 10b, and the other end is the second positive cover plate assembly 110a. A signal transmission antenna 4 is provided on the negative cover plate assembly 10b. The signal transmission antenna 4 is connected to the antenna connection line 5, and no signal transmission antenna 4 is provided on the second positive cover plate assembly 110a. The negative electrode member 303 of the chip assembly 30 is pulled to the negative electrode side to be connected to the antenna connection line 5 on the negative electrode side. After welding is completed, the connection part needs to be coated with an insulating and anti-corrosion film to prevent the welded part from being corroded by the electrolyte. Subsequently, the antenna connection line 5 is pulled together to the negative electrode post lead-out piece 502 on the negative cover plate assembly 10b for laser welding. The positive electrode member 302 of the chip assembly 30 is pulled to the positive electrode post lead-out piece 402 on the second positive cover plate assembly 110a for laser welding, so that the chip 301 can be self-powered by the electrode core 20 subsequently. Figure 8 The dotted line in it shows the signal transmission position.

[0096] Similarly, when antenna holes 11 are provided on both the positive electrode side and the negative electrode side, the connection schematic diagram of the chip assembly 30 inside the battery 100 and the signal transmission antenna 4 on the positive electrode side and the signal transmission antenna 4 on the negative electrode side is as Figure 10 shown. Combining Figures 4 - 5 and Figure 10, both ends of the housing body are open ends. One end of the housing body is the positive cover assembly 10a, and the other end is the negative cover assembly 10b. Signal transmission antennas 4 are provided on both the positive cover assembly 10a and the negative cover assembly 10b, and the signal transmission antennas 4 are connected to the corresponding antenna connection wires 5. The positive component 302 of the chip assembly 30 is pulled to the positive side and connected to the antenna connection wire 5 on the positive side. After welding is completed, the connection part needs to be coated with an insulating and anti-corrosion film to prevent the welded part from being corroded by the electrolyte. Subsequently, the antenna connection wires 5 are pulled together to the positive terminal lead-out piece 402 on the positive cover assembly 10a for laser welding. The negative component 303 of the chip assembly 30 is pulled to the negative side and connected to the antenna connection wire 5 on the negative side. After welding is completed, the connection part needs to be coated with an insulating and anti-corrosion film to prevent the welded part from being corroded by the electrolyte. Subsequently, the antenna connection wires 5 are pulled together to the negative terminal lead-out piece 502 on the negative cover assembly 10b for laser welding, so that the chip 301 can be self-powered by the electrode core 20 subsequently. Figure 10 The dashed line in it shows the signal transmission position.

[0097] In some embodiments not shown in the figure, only one end of the housing body is an open end, and the cover assembly 10 is the total cover assembly 10c, and the total cover assembly 10c is provided at the open end.

[0098] The signals collected by the chip 301 are transmitted to the outside of the external battery 100 through the positive terminal 40, the negative terminal 50, and the signal transmission antenna 4.

[0099] In order to overcome the influence of the electromagnetic shielding effect of the metal housing body of the battery 100 on the signal transmission of the internal chip 301 to the outside, the signal transmission of the internal chip 301 of the battery 100 mainly uses the carrier transmission technology, which has the advantages of long transmission distance, strong anti-interference ability, and easy implementation. The carrier signal can be generated in various ways, such as sine waves, triangular waves generated by an oscillation circuit, etc. During the carrier transmission process, the original signal detected by the internal chip 301 of the battery 100 is modulated onto the carrier signal, and the modulation method can be one or a combination of amplitude modulation, frequency modulation, and phase modulation. Then, the signal loaded onto the carrier signal is transmitted through a communication channel, and the communication channel can be one or a combination of wires, metal wires, optical fibers, or wireless transmission media (air), etc.

[0100] The chip 301 is connected to the positive terminal 40 through the positive component 302 and connected to the negative terminal 50 through the negative component 303. Therefore, the positive terminal 40 and the negative terminal 50 can be used as communication channels to transmit signals. In this way, such as Figures 7 - 8 , Figure 10As shown, the signal can not only be transmitted outward through the pole positions of the positive pole post 40 and the negative pole post 50, but also be transmitted through the signal transmission antenna 4 in the antenna hole 11. The battery 100 of the present invention has two channels: the pole post + the signal transmission antenna 4.

[0101] When the signal loaded on the carrier signal is wirelessly transmitted outward through the pole positions of the positive pole post 40 and the negative pole post 50, the transmission distance is in the range of 0.01m - 1m. At the signal transmission antenna 4, because there is no metal shell blocking the antenna hole 11, the signal transmission ability at this position is stronger. Moreover, the signal transmission antenna 4 made of semiconductor silicon as the base material can further enhance the outward signal transmission. The outward transmission method is wireless transmission, and the transmission distance is in the range of 1m - 50m. At the receiving end, the signal receiving device 200 restores the received carrier signal to the original chip 301 signal through demodulation technology. The signal receiving device 200 is connected to the signal display device 300, so that the signal information detected by the chip 301 inside the battery 100 can be displayed on the signal display device 300 outside the battery 100. The demodulation process is the reverse process of modulation. It extracts the original chip 301 signal information according to the changes in the amplitude, frequency or phase of the carrier signal. Exemplarily, the signal receiving device 200 can be the host of a computer, and the signal display device 300 can be the monitor of a computer. The signal receiving device 200 and the signal display device 300 can be connected through the wire 400 or can also be connected wirelessly.

[0102] Compared with other external chips that need to be connected to additional lines for power supply, this built-in chip 301 can be powered by the battery 100 itself without external additional line power supply. The average power consumption of the chip 301 during operation is <50mW, and the power consumption during dormancy is <50μW, with low energy consumption and obvious advantages.

[0103] According to the battery 100 of the embodiment of the present invention, by setting the above-mentioned cover plate assembly 10, the signal of the chip 301 inside the battery 100 can be effectively transmitted to the outside of the battery 100 through the signal transmission antenna 4, which can effectively improve the signal transmission ability, thereby achieving the purpose of effectively monitoring the internal signal of the battery 100 outside the battery 100, and is beneficial to improving the safety of the battery 100.

[0104] In some embodiments of the present invention, the antenna connection line 5 is adapted to be connected to the one of the positive electrode member 302 and the negative electrode member 303 that is close to the antenna connection line 5. Connecting nearby makes the length of the antenna connection line 5 not too long, which is beneficial to saving the material of the antenna connection line 5 and avoiding interference and entanglement between the antenna connection line 5 and other structures inside the battery 100.

[0105] In some embodiments of the present utility model, referring to Figures 7 - 8 , Figure 10 as shown, the battery 100 further includes a core 20 disposed inside the housing. The core 20 has a positive electrode tab 201 and a negative electrode tab 202. The positive electrode member 302, the positive electrode tab 201 are connected to the positive electrode terminal 40, and the negative electrode member 303, the negative electrode tab 202 are connected to the negative electrode terminal 50. The chip assembly 30 is connected to the positive electrode terminal 40 of the battery 100 through the positive electrode member 302, and the chip assembly 30 is connected to the negative electrode terminal 50 of the battery 100 through the negative electrode member 303. A closed loop is formed between the chip assembly 30 and the core 20 of the battery 100, and the core 20 of the battery 100 can supply power to the chip assembly 30, forming an integrated self-powered battery chip assembly, improving the integration degree of the battery 100 and the chip assembly 30. In addition, the positive electrode member 302, the positive electrode tab 201 are connected to the positive electrode terminal 40, and the negative electrode member 303, the negative electrode tab 202 are connected to the negative electrode terminal 50. On the one hand, it can make the internal structure of the battery 100 more compact and improve the utilization rate of the internal space of the battery 100; on the other hand, it can monitor the core 20 and improve the accuracy of evaluation and the safety of the battery 100.

[0106] Optionally, the positive electrode member 302 can be a rigid conductive member or a flexible conductive member, such as a flexible wire. Similarly, the negative electrode member 303 can be a rigid conductive member or a flexible conductive member, such as a flexible wire.

[0107] In some embodiments, the battery 100 described in the present utility model can be a blade-shaped battery. For example, the length range of the blade-shaped battery can be 400 mm - 700 mm to form a short blade battery; or for another example, the length of the blade-shaped battery can be greater than 700 mm to form a long blade battery. The battery 100 can also be a cylindrical battery, or a square battery, or a soft-pack battery. The method for designing the internal chip signal transmission structure of the battery 100 is applicable to all battery structures containing the cover plate 2, but only the size and position of the antenna holes 11 in the cover plate 2 need to be adjusted and modified according to different battery configurations.

[0108] The number of chip assemblies 30 inside the battery 100 can be one or more. For example, in the Figures 7 - 8 example, the number of chip assemblies 30 inside the battery 100 can be one, Figure 9 showing a schematic diagram of single-chip signal reception and display. If two or more chip assemblies 30 are implanted inside the battery 100 at the same time, the cover plates 2 on both sides can be improved in design, with multiple antenna holes 11 designed to increase the stability of signal transmission, strengthen the signal transmission distance, and avoid crosstalk between the signals of multiple chips 301. In the Figure 10 example, the number of chip assemblies 30 inside the battery 100 can be two.Figure 10 Shows a schematic diagram of dual-chip signal transmission inside the battery 100, Figure 11 illustrates a schematic diagram of dual-chip signal reception and display. Through the design of the two side covers 2, the signals of the dual chips inside the battery 100 can effectively transmit wireless signals outward from the signal transmission antennas 4 at both ends of the battery 100.

[0109] Optionally, the battery 100 according to an embodiment of the present invention can be a lithium battery, a lead-acid battery, etc.

[0110] For the battery 100 according to an embodiment of the present invention, the internal chip signal transmission structure design mainly consists of two parts: the cover plate assembly 10 and the intelligent chip assembly 30. Connecting the two can overcome the barrier of the internal chip 301 signal transmission (the shielding effect of the metal shell), enabling the internal chip 301 signal to be effectively transmitted to the outside of the battery 100, thereby achieving the purpose of monitoring the internal signal of the battery 100 outside the battery 100.
