[0044] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0045] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0046] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0047] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0048] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0049] According to one embodiment of the present application, a housing is provided. Figures 1 to 6 As shown, the housing includes a plate body 1, a transmission mechanism 2 and a monitoring device 3. The transmission mechanism 2 is connected to the plate body 1. The monitoring device 3 is located on one side of the plate body 1 in the thickness direction, and the monitoring device 3 includes a wireless communication module, and the wireless communication module can transmit signals through the transmission mechanism 2.

[0050] In this example, a transmission mechanism 2 is provided on the plate body 1 of the shell, and the transmission mechanism 2 is provided through the plate body 1 along the thickness direction of the plate body 1. The wireless communication module of the monitoring device 3 is arranged opposite to the transmission mechanism 2 to improve the electromagnetic shielding problem, thereby facilitating the wireless communication module to transmit signals through the transmission mechanism 2.

[0051] Among them, the plate body 1 is a metal part. That is, the plate body 1 can be a metal material such as metal aluminum or aluminum alloy, which has high strength, but will produce electromagnetic shielding. It has a strong shielding effect on electromagnetic signals. That is, the metal shields the far-field of the radiation interference source by reflecting and absorbing electromagnetic waves, that is, it simultaneously shields the electric field and magnetic field components generated by the field source. The shielding effect caused by the metal shell of the battery causes the internal sensor signal in the 10-1000MHz frequency band to be attenuated by 60dB to 120dB during transmission. A monitoring device 3 is provided inside the battery, and the battery shell 110 has an electromagnetic shielding effect, which affects the transmission of wireless signals.

[0052] In this example, the transmission mechanism 2 penetrates the plate body 1 along the thickness direction of the plate body 1. The transmission mechanism 2 is arranged to penetrate the plate body 1 along the thickness direction, and the wireless communication module is arranged opposite to the transmission mechanism 2, that is, the position of the wireless communication module corresponds to the position of the transmission mechanism 2, and the wireless communication module can receive or send signals through the transmission mechanism 2, thereby improving the problem of electromagnetic shielding of the plate body 1. For example, the transmission mechanism 2 is arranged to penetrate the plate body 1 along the thickness of the plate body 1, the wireless communication module is arranged on one side of the plate body 1 along the thickness direction, and the wireless communication module is located directly below or directly above the transmission mechanism 2, etc.

[0053] like Figure 4 and Figure 5 , Figure 7 As shown, the board body 1 has an inner surface 12 and an outer surface 11 that is disposed away from the inner surface 12. After the battery is assembled, the inner surface 12 is located inside the battery, and the outer surface 11 is located outside the battery. The monitoring device 3 is disposed on one side of the inner surface 12 of the board body 1, and can be used to monitor the temperature, air pressure, pressure and other information inside the battery, and send signals to the outside through the wireless communication module.

[0054] In this example, the monitoring device 3 further includes a functional module, and the functional module is electrically connected to the wireless communication module. The functional module includes one or more of a temperature sensor, an air pressure sensor, and a pressure sensor. Those skilled in the art may determine the function according to actual conditions, and no specific limitation is made here.

[0055] The functional module can detect various parameters inside the battery, and the wireless communication module converts the acquired parameters such as the temperature of the battery body into a carrier signal and sends it to an external data receiving device, which receives the carrier signal and converts it into various parameters of the corresponding battery body, and then the battery monitoring server stores the data of each battery. The wireless communication module is arranged relative to the transmission mechanism 2, so as to improve the electromagnetic shielding problem, so that the wireless communication module can transmit signals through the transmission mechanism 2.

[0056] Each monitoring device 3 may include multiple functional sensors to detect different signals to improve applicability. Alternatively, multiple monitoring devices 3 and multiple transmission mechanisms 2 may be provided in the housing. A transmission mechanism 2 is provided corresponding to the position of the wireless communication module of each monitoring device 3. By providing multiple monitoring devices 3, parameters at different positions can be detected, so that the internal information of the battery and its changes can be detected more comprehensively, the operating status of the battery can be more effectively grasped, and the battery safety is higher.

[0057] In this example, the monitoring device 3 can be set to a square shape. In order to reduce the impact on the battery cell 120, the height of the monitoring device 3 needs to be less than or equal to 5mm, for example, the height of the monitoring device 3 is 3mm, 4mm or 5mm, etc. The length range of the monitoring device 3 is less than or equal to 40mm, for example, the length of the monitoring device 3 can be 20mm, 30mm or 40mm, etc. The width range of the monitoring device 3 is less than or equal to 30mm, for example, the width of the monitoring device 3 can be 10mm, 20mm or 30mm, etc. Of course, the specific shape and size of the monitoring device 3 can be determined by those skilled in the art according to the actual situation and no specific limitation is made here.

[0058] The monitoring device 3 of the present application reduces the complicated arrangement of wired circuits by wireless communication, and avoids the operation of drilling holes and wiring the battery, without causing damage to the battery structure.

[0059] In this example, the monitoring device 3 needs power supply to enter the working state, and the power supply voltage of the monitoring device 3 is within the battery working voltage range. Therefore, the system circuit of the entire monitoring device 3 can be shared with the battery circuit, and the monitoring device 3 can be self-powered by the battery.

[0060] In one example, the transmission mechanism 2 may be an insulating member 21. The insulating member 21 is disposed through the board body 1 along the thickness direction of the board body 1, and the wireless communication module corresponds to the position of the insulating member 21. For example, the wireless communication module is disposed directly below or directly above the insulating member 21.

[0061] The transmission mechanism 2 may be a ceramic block, or other insulating materials. For example, the transmission mechanism 2 may be made of at least one of polypropylene, polyvinylidene fluoride, polyethylene, polymethyl methacrylate, and polyvinyl acetate. Those skilled in the art may determine the material according to actual conditions, and no specific limitation is made here.

[0062] In this example, the insulating member 21 may be in a square or cylindrical shape, and the structure and shape of the first through hole 13 match the insulating member 21. Those skilled in the art may determine the shape according to actual conditions, and no specific limitation is made here.

[0063] In one example, if 3 to Figure 5 As shown, the plate body 1 is provided with a first through hole 13 , and the transmission mechanism 2 is located in the first through hole 13 and seals the first through hole 13 .

[0064] As 3 to Figure 5As shown, in this example, the plate body 1 is provided with a first through hole 13 along the thickness direction, and the transmission mechanism 2 is provided in the first through hole 13 and can seal the first through hole 13. The transmission mechanism 2 can be completely embedded in the first through hole 13. Alternatively, a portion of the transmission mechanism 2 is provided in the first through hole 13, and one end of the transmission mechanism 2 can be provided protruding from the surface of the plate body 1. Alternatively, the thickness of the transmission mechanism 2 can also be set to be smaller. That is, the thickness of the transmission mechanism 2 is less than the thickness of the plate body 1, so that the thickness of the electromagnetic signal passing through the transmission mechanism 2 can be shortened.

[0065] Of course, the thickness of the transmission mechanism 2 and the manner in which it is arranged in the first through hole 13 can be determined by those skilled in the art according to actual conditions, and no specific limitation is made here.

[0066] In an example, Figure 4 and Figure 5 As shown, the transmission mechanism 2 is provided with a welding piece 22 along the circumferential direction, and the welding piece 22 is suitable for welding with the inner wall of the first through hole 13 .

[0067] like Figure 4 and Figure 5 As shown, the transmission mechanism 2 is provided with a welding member 22 along the circumferential direction. When the transmission mechanism 2 is connected to the plate body 1, the welding member 22 can be welded to the inner wall of the first through hole 13 to seal the first through hole 13. For example, the welding member 22 can be metal aluminum, etc., and the metal aluminum is wound around the insulating member 21 and welded to the inner wall of the first through hole 13 through the surrounding metal aluminum.

[0068] Of course, the transmission mechanism 2 can also be connected to the plate body 1 by other connection methods, and the first through hole 13 can be sealed. For example, the transmission mechanism 2 can also be connected to the plate body by bonding, etc. Those skilled in the art can determine according to actual conditions, and no specific limitation is made here.

[0069] In an example, Figures 1 to 5 As shown, the shell includes an insulating plate 4 , which is connected to one side of the plate body 1 in the thickness direction, and the monitoring device 3 is connected to one end of the insulating plate 4 away from the plate body 1 .

[0070] like Figures 1 to 5 As shown, the housing of the present application further includes an insulating plate 4, which is connected to one side of the plate body 1 along the thickness direction. That is, the insulating plate 4 is installed on the inner surface 12 of the plate body 1 for insulation inside the battery structure. The monitoring device 3 is connected to one end of the insulating plate 4 away from the plate body 1 to reasonably utilize the space inside the battery.

[0071] In an example, Figure 4 and Figure 5As shown, the insulating plate 4 is provided with a second through hole 41 , and the second through hole 41 is arranged opposite to the monitoring device 3 .

[0072] like Figure 4 and Figure 5 As shown, in this example, the monitoring device 3 is arranged opposite to the second through hole 41, for example, the monitoring device 3 can be located directly below the second through hole 41. The electromagnetic signal of the monitoring device 3 can pass through the second through hole 41 for transmission, thereby reducing the influence of the insulating plate 4 on the transmitted electromagnetic signal.

[0073] In this example, the second through hole 41 is connected to the first through hole 13. For example, the second through hole 41 may be located directly below the first through hole 13. The insulating member 21 is disposed in the first through hole 13, which can shorten the distance that the electromagnetic signal passes through the insulating member 21.

[0074] The second through hole 41 may be in a circular, square or oval shape. The size of the second through hole 41 may be set according to the size of the monitoring device 3. Of course, the shape and size of the second through hole 41 may be determined by those skilled in the art according to actual conditions, and are not specifically limited here.

[0075] In this example, if Figure 1 and Figure 2 As shown, the monitoring device 3 is screwed to the insulating plate 4 via a fastener 53 .

[0076] The monitoring device 3 includes a circuit board, and the functional module and the wireless communication module are arranged on the circuit board. The fastener 53 can be passed through the circuit board and screwed on the insulating plate 4 to connect the monitoring device 3 to the insulating plate 4. The fastener 53 can be a bolt or a stud, etc., which can be determined by those skilled in the art according to the actual situation and is not specifically limited here.

[0077] In this example, the circuit board can be a square structure, and fasteners 53 are respectively provided at the four corners of the circuit board for fixed connection. The circuit board can also be set to other structures, such as round or other irregular shapes, etc., which can be determined by those skilled in the art according to actual conditions and are not specifically limited here.

[0078] A plurality of fasteners 53 may be provided, and the plurality of fasteners 53 are arranged at intervals through the circuit board to improve the connection stability of the monitoring device 3. For example, four, five or six fasteners 53 may be provided. Those skilled in the art may determine the number according to the actual situation, and no specific limitation is made here.

[0079] Alternatively, the housing further comprises a fastener 53, and the monitoring device 3 is connected to the plate body via the fastener 53. The monitoring device 3 may also be directly connected to the plate body via the fastener 53. The specific connection method and connection structure are the same as those for connecting to the insulating plate, and are not described in detail herein.

[0080] In an example, Figures 3 to 5 As shown, the insulating plate 4 is provided with a hook 51 , and the monitoring device 3 is hooked to the insulating plate 4 via the hook 51 .

[0081] like Figures 3 to 6 As shown, a hook 51 is provided at one end of the insulating plate 4 away from the plate body 1, and the monitoring device 3 can be connected to the insulating plate 4 through the hook 51. Two hooks 51 are provided, and the two hooks 51 are arranged diagonally. The insulating plate 4 is also provided with two limit parts 52, and the two limit parts 52 are arranged diagonally. That is, the hooks 51 and the limit parts 52 are arranged alternately, and the monitoring device 3 is connected to the two hooks 51. The two limit parts 52 can abut against the monitoring device 3 to limit and fix the monitoring device 3 to improve the stability of the monitoring device 3. For example, the monitoring device 3 is square, the two limit parts 52 are respectively located at a group of diagonal positions of the monitoring device 3, and the two hooks 51 are located at another group of diagonal positions of the monitoring device 3.

[0082] The positions of the hook 51 and the limiting portion 52 avoid the positions of the liquid injection port 7 and the explosion-proof valve.

[0083] In this example, the hook 51 can be configured as an elastic hook 51 to facilitate installation and removal of the monitoring device 3 .

[0084] Of course, the monitoring device 3 can also be clamped on the insulating plate 4 through other clamping structures. Those skilled in the art can determine according to actual conditions, and no specific limitation is made here.

[0085] In one example, the board body 1 is provided with a hook 51, and the monitoring device 3 is connected to the insulating board body 1 by the hook 51. That is, the monitoring device 3 can also be directly connected to the board body 1 by means of a hook connection. A hook 51 is provided at one end of the board body 1, and the monitoring device 3 is connected to the board body 1 by the hook 51. Of course, the specific implementation method of the monitoring device 3 being connected to the board body 1 is the same as the above-mentioned method of the monitoring device 3 being connected to the insulating board 4, and will not be repeated here.

[0086] In an example, Figures 3 to 5 As shown, the housing further includes a protective shell 6 , the monitoring device 3 is disposed in the protective shell 6 , and the protective shell 6 is connected to the insulating plate 4 .

[0087] like Figures 3 to 5As shown, the housing further includes a protective shell 6, and the monitoring device 3 is disposed in the protective shell 6, that is, the wireless communication module and the functional module can be disposed in the protective shell 6, and the protective shell 6 is connected to the insulating plate 4. By disposing the monitoring device 3 in the protective shell 6, the monitoring module can be prevented from being impacted and squeezed, and this design ensures the structural stability of the monitoring device 3.

[0088] In this example, the protective shell 6 can be connected to the insulating plate 4 by means of a hook 51, or can be connected to the insulating plate 4 by means of a fastener 53. Those skilled in the art can determine the method according to actual conditions and no specific limitation is made here.

[0089] In an example, Figures 3 to 5 As shown, the protective shell 6 is provided with a protective cavity 61 , the monitoring device 3 is arranged in the protective cavity 61 , and the open end of the protective cavity 61 abuts against the insulating plate 4 .

[0090] like Figures 3 to 5 As shown, in this example, the protective shell 6 is provided with a protective cavity 61, the monitoring device 3 is arranged in the protective cavity 61, and the open end of the protective cavity 61 abuts against the insulating plate 4. The open end of the protective cavity 61 abuts against the insulating plate 4, and the protective cavity 61 can be sealed. For example, a sealant or a sealing sponge is arranged between the open end of the protective cavity 61 and the insulating plate 4. This can prevent the infiltration of part of the electrolyte and reduce the corrosion of the electrolyte to the monitoring module.

[0091] In one example, a protective coating is provided on the outside of the monitoring device 3. Since the electrolyte inside the battery is corrosive, it is necessary to ensure that the monitoring device 3 has corrosion resistance. To this end, an anti-corrosion coating, such as epoxy resin, can be selected to coat the monitoring device 3 to isolate the circuit board from the external environment, ensuring that the problem of electrolyte corrosion of the circuit does not occur during long-term use.

[0092] According to a second aspect of the utility model, a battery is provided, which comprises the housing of the above embodiment.

[0093] After the battery is manufactured, the finished battery is prepared after the steps of shelling, welding, liquid injection, formation, and capacity division. The entire battery is completely sealed, and the lithium battery in this technical solution can monitor the changes in the internal temperature of the battery online. The monitoring device 3 in the battery has a temperature sensor and a wireless communication module. The wireless signal is received by an external receiving device, and the temperature inside the battery is monitored in real time through the temperature sensor set inside the battery.

[0094] In this example, if Figure 7As shown, the battery of the utility model includes the shell of the above embodiment. The shell can be a battery end cover, and the end cover sealing cover is arranged at the end of the battery shell 110. The battery end cover includes a plate body 1, and a transmission mechanism 2 and a monitoring device 3 are arranged on the plate body 1. The transmission mechanism 2 is arranged through the plate body 1 along the thickness direction of the plate body 1, and the wireless communication module of the monitoring device 3 is arranged opposite to the transmission mechanism 2 to improve the electromagnetic shielding problem, so that the wireless communication module can transmit signals through the transmission mechanism 2.

[0095] In this example, the monitoring device 3 is provided on both opposite sides of the shell. For example, two groups of battery end covers are provided, and the two groups of battery end covers are respectively provided at opposite ends of the battery shell 110. The monitoring devices 3 on the battery end covers at both ends can detect parameters at different positions inside the battery, so that the internal information of the battery and its changes can be detected more comprehensively, the operating status of the battery can be more effectively grasped, and the battery safety is higher. Alternatively, the monitoring devices 3 can also be provided on the opposite sides of the inner wall of the battery shell 110, and the battery shell 110 is provided with a transmission mechanism 2 at the corresponding position of each monitoring device 3.

[0096] In this example, a battery cell 120 is disposed inside the battery housing 110, and battery end covers are connected to both ends of the battery housing 110 for sealing. A positive electrode column 8 and a negative electrode column 9 are also connected to the two cover plates, respectively.

[0097] In one example, a plurality of monitoring devices 3 are arranged at intervals in the shell. That is, the shell is a battery shell 110, and a plurality of monitoring devices 3 are arranged on the inner wall of the battery shell 110. Alternatively, the inner wall of the battery shell 110 and the inner wall of the battery end cover are both provided with monitoring devices 3, so that the internal information of the battery and its changes can be detected more comprehensively, the operating status of the battery can be more effectively grasped, and the battery safety is higher.

[0098] According to a third aspect of the utility model, an electric device is provided, which includes the battery of the above embodiment.

[0099] In this example, the electric device includes the battery of the above embodiment. The battery is provided with a housing of the above embodiment, and the housing includes a plate body 1. A transmission mechanism 2 is provided on the plate body 1, and the transmission mechanism 2 is provided through the plate body 1 along the thickness direction of the plate body 1. The wireless communication module of the monitoring device 3 is provided opposite to the transmission mechanism 2 to improve the electromagnetic shielding problem, so that the wireless communication module can transmit signals through the transmission mechanism 2.

[0100] The power-consuming device may be a power-consuming module in a vehicle, such as an electric car or an electric motorcycle, or other power-consuming devices that require battery power, such as an energy storage cabinet or other electrical appliances. Those skilled in the art may determine the method according to actual conditions, and no specific limitation is made here.

[0101] The above embodiments focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.
