[0097] In some embodiments of the present utility model, a pole hole 23 for the pole post to pass through is provided on the cover plate 2, and the pole hole 23 is a positive pole hole 211 for the positive pole post 40 to pass through or a negative pole hole 221 for the negative pole post 50 to pass through. For example, in Figure 4 the illustrated example, the cover plate assembly 10 is a positive cover plate assembly 10a, and the pole hole 23 is the positive pole hole 211 for the positive pole post 40 to pass through. In Figure 5 the illustrated example, the cover plate assembly 10 is a negative cover plate assembly 10b, and the pole hole 23 is the negative pole hole 221 for the negative pole post 50 to pass through.

[0098] In some embodiments of the present utility model, referring to Figure 4 the illustration, the cover plate assembly 10 is a positive cover plate assembly 10a, and the positive pole hole 211 is provided between the installation groove 11 and the liquid injection hole 212. By reasonably utilizing the position of the cover plate 2, the structure of the cover plate assembly 10 can be made more compact, facilitating production and processing.

[0099] In some embodiments of the present utility model, referring to Figure 5As shown, the cover plate assembly 10 is a negative electrode cover plate assembly 10b, and the positive electrode column hole 211 is arranged between the mounting groove 11 and the explosion-proof valve hole 222. Reasonable use of the position of the cover plate 2 can make the structure of the cover plate assembly 10 more compact and convenient for production and processing.

[0100] In some embodiments of the present invention, the cover plate 2 is provided with a positive electrode hole 211 for the positive electrode column 40 to pass through and a negative electrode hole 221 for the negative electrode column 50 to pass through. Figure 6 As shown, the cover plate assembly 10 is a total cover plate assembly 10c, and a liquid injection hole 212 and an explosion-proof valve hole 222 are provided on the total cover plate assembly 10c. The mounting groove 11 is close to the liquid injection hole 212, and the liquid injection hole 212, the mounting groove 11, the positive pole hole 211, the negative pole hole 221, and the explosion-proof valve hole 222 are arranged in sequence. Of course, on the total cover plate assembly 10c not shown in the figure, the mounting groove 11 can also be arranged close to the explosion-proof valve hole 222, for example, the liquid injection hole 212, the positive pole hole 211, the negative pole hole 221, the mounting groove 11, and the explosion-proof valve hole 222 are arranged in sequence. Reasonable use of the positions of the cover plate 2 and the insulating plate 3 can make the structure of the cover plate assembly 10 more compact and convenient for production and processing.

[0101] It is understandable that when the cap 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.

[0102] In some embodiments of the present invention, referring to Figure 1 , Figures 4-9 As shown, the cover plate assembly 10 further includes an insulating plate 3, which is arranged on a side of the cover plate 2 away from the mounting groove 11, the mounting groove 11 is spaced apart from the insulating plate 3, and the corresponding pole hole 23 on the cover plate 2 passes through the insulating plate 3 along the thickness direction of the insulating plate 3. Figure 1 As shown, the cover plate 2 and the insulating plate 3 form a combined plate 1, the insulating plate 3 is arranged on the lower side of the cover plate 2, and the cover plate 2 is provided with a mounting groove 11, the upper end of the mounting groove 11 penetrates to the upper side of the cover plate 2, and the lower end of the mounting groove 11 is separated from the lower side of the insulating plate 3. Since the lower end of the mounting groove 11 is separated from the lower side of the insulating plate 3, the signal transmission structure 4 is isolated from the internal space of the battery 100 by at least a part of the insulating plate 3, so as to prevent the electrolyte inside the battery 100 from corroding the signal transmission structure 4. The mounting groove 11 is opened on the upper surface of the cover plate 2, which will not cause major damage to the cover plate 2, nor will it damage the sealing of the battery 100.

[0103] In some embodiments, 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 inside of the battery 100 on the other side of the insulating plate 3, thereby preventing the electrolyte inside the battery 100 from being electrically conductive to the cover plate 2. For example, the insulating plate 3 can be a plastic material, such as a polypropylene material, or a rubber material or a silicone material. Optionally, the insulating plate 3 can be a spacer of the battery 100.

[0104] Reference Figure 4 , Figure 6 As shown, the positive electrode column 40 includes a positive electrode column body 401 and a positive electrode column lead-out sheet 402. The positive electrode column body 401 passes through the positive electrode column hole 211, and the positive electrode column lead-out sheet 402 is connected to the positive electrode column body 401. The positive electrode column lead-out sheet 402 is located on the side of the insulating plate 3 away from the cover plate 2. By providing the positive electrode column lead-out sheet 402, it is convenient to connect the pole core 20 and the chip assembly 30 inside the battery 100 with the positive electrode column 40.

The negative electrode column body 501 passes through the negative electrode column hole 221, and the negative electrode column lead-out piece 502 is connected to the negative electrode column body 501. The negative electrode column lead-out piece 502 is located on the side of the insulating plate 3 away from the cover plate 2. By providing the negative electrode column lead-out piece 502, it is convenient to connect the pole core 20 and the chip assembly 30 inside the battery 100 with the negative electrode column 50.

[0106] Optionally, the number of the signal forwarding structures 4 on each cover assembly 10 may be one or more.

[0107] Reference Figures 4-9 As shown, the battery 100 according to the embodiment of the second aspect of the utility model includes a pole, a shell body 60, 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 60 is an open end, and the cover assembly 10 is arranged at the open end, and 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.

[0108] The chip assembly 30 includes a chip 301, which is embedded in the housing body 60. The chip 301 is suitable for being electrically connected to the pole, and the chip 301 transmits the collected signal to the signal receiving module 42 via the pole. In other words, after collecting the signal, the chip 301 can transmit the collected signal to the pole, and the pole transmits the signal to the signal receiving module 42 by wireless transmission. The signal transmission module 44 amplifies the signal received by the signal receiving module 42 and transmits it to an external device receiving the signal, such as the battery management system 200.

[0109] In some embodiments of the present utility model, the pole column includes a positive pole column 40 and a negative pole column 50. At least one of the positive pole column 40 and the negative pole column 50 is disposed in the pole column hole 23 on the cover plate assembly 10, and the chip 301 is adapted to be electrically connected to the positive pole column 40 and the negative pole column 50.

[0110] The battery 100 according to the embodiment of the present utility model has one communication channel of the pole column. Since the signal transfer structure 4 is close to the pole column, it can receive the signal of the chip 301 transmitted by the pole column, amplify the signal of the chip 301 and then strengthen and transmit it outward.

[0111] For the battery 100 according to the embodiment of the present utility model, by providing the above-mentioned cover plate assembly 10, the signal of the chip 301 inside the battery 100 can be first transmitted to the signal transfer structure 4 through the pole column, and then transmitted to the outside of the battery 100 through the signal transfer structure 4, which can effectively improve the signal transmission ability, so as to achieve 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.

[0112] In some embodiments of the present utility model, the chip 301 includes a circuit structure and a detection structure. The detection structure is electrically connected to the circuit structure. The chip assembly 30 further includes a positive electrode member 302 and a negative electrode member 303. One end of the positive electrode member 302 is electrically connected to the circuit structure, and the other end of the positive electrode member 302 is adapted to be connected to the positive pole column 40. One end of the negative electrode member 303 is electrically connected to the circuit structure, and the other end of the negative electrode member 303 is adapted to be connected to the negative pole column 50. Thus, the detection structure is electrically connected to the circuit structure, and the circuit structure is electrically connected to the pole column of the battery 100 through the positive electrode member 302 and the negative electrode 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. The battery 100 and the chip assembly 30 form an integrated self-powered battery chip assembly, without the need to provide an external power source to supply power to the chip assembly 30, which improves the integration of the battery 100 and the chip assembly 30.

[0113] It should be further noted that the detection structure can be a temperature sensor and its associated connecting member to detect the temperature of the battery 100; the detection structure can be a stress detection device to detect the stress condition inside the battery 100; the detection structure can also be a pressure detection device to detect the air pressure inside the battery 100. That is to say, according to different monitoring contents and requirements, the detection structure inside the chip 301 can be replaced according to different test needs. Thus, the detection structure includes but is not limited to a temperature sensor, a stress detection device, a pressure detection device, etc.

[0114] 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 the present application, the chip component 30 is arranged inside the battery housing. The chip component 30 can monitor a single battery 100, can effectively monitor the temperature, air pressure and stress changes of the battery 100, 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.

[0115] In some embodiments, the detection structure of the chip component 30 can be a sensor, and the circuit structure of the chip component 30 can be a printed circuit board (the second PCB board). The sensor is arranged on the second PCB board, and the sensor and the second PCB board are an integrated structure. There are three main modules on the PCB board, namely a power supply circuit module, a signal acquisition circuit module and an antenna structure (also called the second on-board antenna circuit module). The setting of these modules can effectively transmit the signal of the chip 301 inside the battery 100 to the outside of the battery 100, so as to achieve the purpose of monitoring the internal signal of the battery 100 outside the battery 100.

[0116] Specifically, the signal detected by the sensor is mainly collected by the signal acquisition circuit module, and then transmitted to the second on-board antenna circuit module. It is transmitted outward through the pole post by being carried on a high-frequency carrier wave in a modulated frequency manner. This technology has the advantages of long transmission distance, strong anti-interference ability and easy implementation. The type of the sensor can be designed and replaced according to requirements, and can be one or a combination of temperature, air pressure and stress sensors. The signal receiving module 42 in the PCB board on the cover plate 2 receives the carrier signal through demodulation technology, and directly transmits the collected information to the battery management system 200 in a wireless or wired manner, or first transmits the collected information to the signal storage module 43 for storage, and then transmits the signal information to the battery management system 200 in a wireless or wired manner.

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 transfer structure 4 is provided on the positive cover plate assembly 10a, and no signal transfer structure 4 is provided on the second negative cover plate assembly 110b. The positive electrode member 302 of the chip assembly 30 is drawn to the positive electrode side and welded to the positive electrode post lead piece 402 on the positive electrode side. After welding, 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. The negative electrode member 303 of the chip assembly 30 is drawn to the negative electrode post lead piece 502 on the second negative cover plate assembly 110b for 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.

[0118] Similarly, when the installation groove 11 is located on the negative electrode side, the schematic diagram of the position of the chip assembly 30 inside the battery 100 and the signal transfer structure 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 transfer structure 4 is provided on the negative cover plate assembly 10b, and no signal transfer structure 4 is provided on the second positive cover plate assembly 110a. The negative electrode member 303 of the chip assembly 30 is drawn to the negative electrode side and welded to the negative electrode post lead piece 502 on the negative electrode side. After welding, 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. The positive electrode member 302 of the chip assembly 30 is drawn to the positive electrode post lead piece 402 on the second positive cover plate assembly 110a for welding, so that the chip 301 can be self-powered by the electrode core 20 subsequently.

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 plate assembly 10a, and the other end is the negative cover plate assembly 10b. A signal transfer structure 4 is provided on both the positive cover plate assembly 10a and the negative cover plate assembly 10b. The positive component 302 of the chip assembly 30 is pulled to the positive side and welded to the positive column lead piece 402 on the positive side. After welding, 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. The negative component 303 of the chip assembly 30 is pulled to the negative side and welded to the negative column lead piece 502 on the negative side. After welding, 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 chip 301 is self-powered by the electrode core 20, Figure 9 The dotted line in

[0120] In some embodiments not shown in the figure, only one end of the housing body is an open end, and the cover plate assembly 10 is the total cover plate assembly 10c, and the total cover plate assembly 10c is arranged at the open end.

[0121] The signal collected by the chip 301 is first stored in the signal transfer structure 4 and then transmitted outward from the signal transfer structure 4 to the outside of the external battery 100.

[0122] Optionally, the welding method between the positive component 302 and the positive column lead piece 402 can be brazing, laser welding, spot welding, etc., and the welding method between the negative component 303 and the negative column lead piece 502 can be brazing, laser welding, spot welding, etc.

[0123] In some embodiments of the present invention, referring to Figures 7-9 As shown, the battery 100 further includes an electrode core 20. The electrode core 20 is arranged in the housing body 60. The electrode core 20 has a positive electrode tab 201 and a negative electrode tab 202. The positive component 302, the positive electrode tab 201 are connected to the positive electrode column 40, and the negative component 303, the negative electrode tab 202 are connected to the negative electrode column 50. The chip assembly 30 is connected to the positive electrode column 40 of the battery 100 through the positive component 302, and the chip assembly 30 is connected to the negative electrode column 50 of the battery 100 through the negative component 303. A closed loop is formed between the chip assembly 30 and the electrode core 20 of the battery 100. The electrode core 20 of the battery 100 can supply power to the chip assembly 30 to form an integrated self-powered battery chip assembly, improving the integration degree of the battery 100 and the chip assembly 30. In addition, the positive component 302, the positive electrode tab 201 are connected to the positive electrode column 40, and the negative component 303, the negative electrode tab 202 are connected to the negative electrode column 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 electrode core 20 and improve the accuracy of evaluation and the safety of the battery 100.

[0124] 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.

[0125] In some embodiments, the battery 100 of the present invention 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 mounting groove 11 in the cover plate 2 need to be adjusted and modified accordingly according to different battery configurations.

[0126] The number of chip components 30 inside the battery 100 can be one or more. For example, in Figures 7-8 the example, the number of chip components 30 inside the battery 100 can be one. If two or more chip components 30 are implanted inside the battery 100 at the same time, the cover plates 2 on both sides can be improved in design, multiple signal transfer structures 4 can be designed to increase the stability of signal transmission, strengthen the signal transmission distance, and avoid crosstalk between the signals of multiple chips 301. In Figure 9 the example, the number of chip components 30 inside the battery 100 can be two. Figure 9 shows a schematic diagram of dual-chip signal transmission inside the battery 100. Through the design of the cover plates 2 on both sides, the signals of the dual chips inside the battery 100 can effectively transmit wireless signals outward from the signal transfer structures 4 at both ends of the battery 100.

[0127] Optionally, the battery 100 according to the embodiments of the present invention can be a lithium battery, a lead-acid battery, etc.

[0128] For the battery 100 according to the embodiments of the present invention, the internal signal acquisition, storage, and transmission methods are applicable to all battery 100 structures, but only the size and position of the mounting groove 11 in the cover plate 2 need to be adjusted and modified accordingly according to different battery 100 configurations.

[0129] Referring to Figure 10As shown in the figure, the energy storage device 1000 according to the third aspect embodiment of the present invention includes a battery management system 200 (i.e., BMS) and the battery 100 of the above embodiment. The battery management system 200 includes a collection module 2001.

When a signal storage module 43 is provided, the signal transmission module 44 is used to transmit the signal stored in the signal storage module 43 to the collection module 2001. In order to enable the signals of the chip 201 inside the battery 100 to be effectively transmitted to the battery management system 200 for combined use, the battery 100 of the present invention cleverly designs a chip signal reception and storage position on the cover plate 2.

The PCB board on the cover plate 2 is connected to the battery management system 200 wirelessly or wiredly. The wireless solution is preferably selected, and the wired method is an alternative. The battery management system 200 will collect the relevant signal information of each battery 100 in the battery module, and then transmit it to the monitoring integrated storage circuit module 20021 for monitoring and analysis. If the status signals such as the temperature and air pressure inside the battery 100 are normal, the indicator light circuit module 20023 will transmit a normal green light indication. If the status signals such as the temperature and air pressure inside the battery 100 are abnormal, the indicator light circuit module 20023 will transmit a red light warning signal to issue a warning alarm reminder. And the communication circuit module 20022 will transmit the monitored relevant information to the terminal in real time and effectively for monitoring and analysis.
