[0001] The present disclosure relates to an aerosol generating device. The present disclosure further relates to a battery module. The present disclosure further relates to a method.

Background Art

[0002] An aerosol generating device is configured to heat an aerosol substrate to generate an aerosol for inhalation. The aerosol generating device comprises a power source in the form of a battery cell. The battery cell may supply power for the operation of the aerosol generating device, for example, the power required to generate an aerosol. The battery cell may be incorporated into a battery module comprising the battery cell and / or other battery module components.

[0003] An aerosol generating device generally has to comprise many components while maintaining a small form factor. Existing approaches involve providing the aerosol generating device components and the battery module in a layered structure. The available space within the aerosol generating device is not optimally utilized. It is desirable to improve the use of the available space within the aerosol generating device.

[0004] The replacement and recycling of the battery module are also important considerations. It may be desirable to access the battery module of the aerosol generating device in order to replace battery module components. It is desirable to make the removal and replacement of battery module components easier and more intuitive. Ensuring the authenticity of replacement battery module components is also an important consideration.

[0005] Furthermore, in relation to the replacement and recycling of battery modules, hazards associated with the removal of battery modules include electrical, chemical, and thermal hazards, as well as the potential for their interactions. Improving safety when accessing and replacing battery modules in aerosol generating devices is desirable.

[0006] In addition, during conventional battery module removal, replacement, and recycling, users are unaware of the condition or characteristics of the battery cells or other battery module components, such as the health or charge status of the battery cells. It is desirable that users have a better understanding of the battery condition or component characteristics when removing, replacing, and recycling battery modules. [Overview of the project] [Problems that the invention aims to solve]

[0007] The object of the present invention is to overcome at least some of the problems mentioned above or other problems mentioned elsewhere. [Means for solving the problem]

[0008] This disclosure provides an aerosol generating device, a battery module, and a method, each having the features described in the claims.

[0009] According to a first aspect of the present invention, an aerosol generating device is provided, comprising a plurality of spaces defined by components of the aerosol generating device, and a battery module having one or more battery module components arranged within the plurality of spaces.

[0010] This structure improves the use of available space within the aerosol generating device. Specifically, the space defined by the components (which can mean the space between components, or the space defined by the gaps between components) is used to accommodate the battery module components. To put it simply, the space can also be considered a "gap" between components, and this gap is at least partially "filled" by placing the battery module components inside.

[0011] Furthermore, since the battery module component can be removed from the space in a single process or movement, the removal of the battery module component is simpler. Moreover, since the replacement battery module component can be installed in the space in a single process or movement, replacement is simpler and more intuitive. This is in contrast to existing methods in which the battery module component is inserted into the aerosol generating device as far as possible and is not inserted into spaces defined by components that may be suitable (or may be specifically designed or positioned) to receive the component. In this example, the space may be suitable (e.g., specifically designed or positioned) to receive one or more battery module components.

[0012] This structure also ensures that genuine replacement parts are used, as it requires a "match" or "fit" between the form factor of the replacement battery module component and the space defined by the component. For example, if an improperly configured battery module is used, its components will not fit into the space of the aerosol generating device.

[0013] In one example, one or more battery module components are detachably arranged in multiple spaces.

[0014] In this way, one or more battery module components can be removed for replacement with new battery module components and / or for recycling the removed battery module components.

[0015] In one example, multiple spaces are defined by one or more casing portions of a printed circuit board (PCB) and / or an aerosol generating device.

[0016] Such a structure facilitates the use of space within the aerosol generating device that would otherwise be wasted or unused during assembly. Furthermore, the PCB and / or one or more casing portions can be advantageously adapted or shaped to define space, thereby accommodating one or more battery module components.

[0017] In one example, one or more battery module components may correspond to one of the spaces, optionally to a specific space, and optionally, one or more battery module components may be shaped or sized to correspond to one of the spaces.

[0018] In this way, the battery module components are optimally matched or fitted into the space. Furthermore, by requiring specific components to be placed in specific spaces (as a form of "poka-yoke" mechanism), improper placement of battery module components within a space can be prevented, thereby improving ease of installation.

[0019] In one example, space is provided or defined by multiple sections.

[0020] That is, the space may be an internal space where components are provided, and the compartment provides the internal space and has an outer boundary or outer surface defined by the components of the aerosol generating device. The compartment may be shaped to receive one or more battery module components.

[0021] In this way, the utilization of the available space within the device is achieved. Furthermore, a safe connection of the battery module components can be made.

[0022] In one example, the battery module includes a first part of the sensor device, and a second part of the sensor device is provided in at least one of the plurality of spaces.

[0023] In this way, the correct (i.e., appropriate) location of one or more battery module components within the plurality of spaces can be determined and ensured (i.e., detected). Such a structure can facilitate the prevention of the operation of the battery module or the aerosol generating device until the battery module components are correctly positioned within the space. Thereby, safety can be improved. Furthermore, such a structure can make it possible to identify non-genuine replacement parts. <00,00079>

[0024] In one example, the second part of the sensor device is configured to detect the first part of the sensor device.

[0025] In this way, the correct (i.e., appropriate) location of one or more battery module components within the plurality of spaces can be determined and ensured.

[0026] In one example, the sensor device includes a proximity sensor.

[0027] [[ID=!7]] In this way, a signal indicating that the orientation of the battery module components is correct can be provided by the sensor.

[0028] In one example, the second portion of the sensor device is provided on a battery module component separate from the battery cell.

[0029] This can simplify installation by reducing issues related to uncertainties in correctly positioning battery module components other than the battery cell. In some examples, it may be possible to easily determine where the battery cell needs to be installed, but in other cases, it may not be easy to determine the correct location of other battery module components. Thus, such a structure ensures the correct placement of battery module components other than the battery cell.

[0030] In one example, the sensor device provides or generates an output signal that authenticates the battery module and / or ensures proper connection.

[0031] In this way, a genuine battery module (or its genuine components) can be verified. Additionally, a proper connection of the battery module (e.g., correct placement and / or correct electrical connection) can be established, thereby improving safety.

[0032] In one example, one or more battery module components include a battery cell and one or more additional battery module components.

[0033] Such a structure improves the use of the internal space available in the aerosol generating device by placing a relatively bulky battery cell in the space defined by the components of the aerosol generating device. This can be in contrast to existing techniques that do not utilize the space that may remain around or adjacent to the battery cell. For example, existing techniques may not place the battery cell within one or more spaces defined by the components of the device, but instead incorporate a layered structure of the battery cell with other components of the aerosol generating device.

[0034] A battery cell may be shaped to be positioned in multiple spaces. That is, a single battery cell may be shaped to be positioned in multiple spaces. A battery cell may contain multiple subcells. A battery cell may have protruding regions that are to be positioned in the aforementioned spaces. Components or parts of a battery cell may extend outward from the space, and such parts may extend between the protruding portions of the battery cell so that a single battery cell can be positioned in multiple spaces.

[0035] In one example, one or more additional battery module components include a battery module hardware protection system and / or interface.

[0036] In this way, the arrangement of battery module components is improved, and additional battery module components can be placed in the space described above. The battery module hardware protection system may include a fuse and / or a protection IC module, or may include a fuse and / or a protection IC module. The interface may include a screen or display. Additionally or alternatively, the interface may include visual indicators configured to indicate battery module component characteristics.

[0037] In one example, a battery module comprises multiple battery module components connected to each other by one or more connecting elements. These connecting elements may be located outside of space.

[0038] In this way, the battery module components can be connected. Furthermore, battery module components positioned within the space can be connected while utilizing the available space within the aerosol generating device. The connection element may have one or more flexible connectors. The flexible connectors may be thin-film connectors or electrical connectors. The flexible connectors may comprise layers of conductors and insulators arranged in parallel. The flexible nature of the connectors allows for the necessary relative movement or manipulation of the components when inserting / removing the battery modules. The flexible function can also improve space saving, as a clearly reserved space for rigid connectors is not necessarily required.

[0039] A second aspect of the present invention provides a battery module for an aerosol generating device, wherein the aerosol generating device comprises a plurality of spaces defined by components of the aerosol generating device, and the battery module comprises one or more battery module components that can be arranged in the plurality of spaces.

[0040] In this way, a favorable battery module for an aerosol generating device is provided, with the associated advantages of improving the use of available space within the aerosol generating device, simplifying the removal and replacement of the battery module, ensuring the authenticity of the battery module, and enhancing safety.

[0041] A second aspect of the present invention may incorporate any or all features of the first aspect of the present invention, as desired or as necessary.

[0042] A third aspect of the present invention provides a method for assembling an aerosol generating device, comprising providing a battery module comprising one or more battery module components, and arranging one or more battery module components within a plurality of spaces defined by the components of the aerosol generating device.

[0043] In this way, a favorable method for assembling an aerosol generating device is provided, with the associated advantages of improving the use of available space within the aerosol generating device, simplifying the removal and replacement of the battery module, ensuring the authenticity of the battery module, and enhancing safety.

[0044] A third aspect of the present invention may, if desired or as needed, incorporate any or all features of the first and / or second aspects of the present invention.

[0045] A fourth aspect of the present invention is provided, a battery module for an aerosol generating device comprising one or more battery module components, wherein the battery module includes a visual indicator as part of the battery module, and the visual indicator is configured to indicate the characteristics of the battery module component.

[0046] This structure allows the operator to determine the characteristics of the battery module components by referring to the battery module, for example, by referring to the battery module itself or only the battery module. This is in contrast to existing examples of aerosol generating devices where the characteristics of the battery module components may be indicated to the operator by the aerosol generating device, but not by the battery module itself. Because the operator only needs to refer to the battery module and not to other systems that may be provided in the aerosol generating device, this structure is highly advantageous in improving safety during the disassembly of the aerosol generating device and during the replacement or recycling of battery module components. In this example, the battery module does not need to be provided as part of the aerosol generating device in order to provide or indicate the characteristics of the battery module components. In other words, the battery module can independently indicate the characteristics, or "status," of the battery module. This is highly advantageous in that it makes it possible to determine the characteristics of the battery module components, thereby facilitating the replacement or recycling of the battery module. Furthermore, the characteristics of the battery module components can be determined without or before insertion into the device. This can lead to the user's decision on whether or not the battery module is suitable for use in the aerosol generating device, i.e., the user may decide not to adopt the battery module in some cases. This improves user convenience because users do not need to insert the battery module into the device to understand its characteristics. The visual indicator being "part" of the battery module may mean that the battery module and the visual indicator are integrally formed. The visual indicator may be attached to the battery module or provided on the surface of the battery module.

[0047] The visual indicator may be distinct from, different from, or separate from the user interface of the aerosol generating device. Conventional aerosol generating devices may have a user interface that indicates, for example, the battery cell charge level. However, this visual indicator is included in (e.g., inherent to) the battery module, rather than receiving signals from another system or component of the aerosol generating device, such as the processor or controller of the aerosol generating device. The visual indicator may provide visual indication without using electronic means. The visual indicator may also be a chemical indicator of the electrical characteristics of the battery module components.

[0048] The visual indicator may be operable to indicate the battery module component characteristics when the battery module is disconnected from the aerosol generating device (i.e., when the battery module is provided separately).

[0049] In one example, a battery module comprises one or more connection elements that connect to one or more battery module components, the one or more connection elements having a visual indicator.

[0050] In this way, the connection elements provided on the battery module can be used as a means to inform the operator of the battery module component characteristics. This improves the safety of removing and replacing battery module components.

[0051] One or more connection elements may be thin-film connectors. One or more connection elements may be flexible connectors. This may allow the connection elements to be placed in a location suitable for operator visibility. One or more connection elements may also be electrical connection elements, which may provide a visual indicator of the electrical characteristics of the battery module components.

[0052] In one example, battery module component characteristics relate to the operation of one or more battery module components.

[0053] In this way, the operator can determine whether the battery module components are functioning correctly or will continue to function correctly.

[0054] A battery module component may be a battery cell, and the battery module component characteristic may be the charge level of the battery cell. Additionally or alternatively, the battery module component characteristic may be a reference or identifying information for the battery module component or the entire battery module. A battery module component may be a battery cell, and the battery module component characteristic may be an indication of the battery cell's expiration date or degradation level. In this way, the operator can determine that a battery cell needs to be replaced by referring to a visual indicator on the battery module, rather than by referring to the user interface of the aerosol generating device.

[0055] In one example, battery module component characteristics relate to the electrical state of one or more battery module components.

[0056] The electrical state could be the current charge level or voltage of the battery cell. In this way, the operator can ensure that the battery cell is discharged and safe to remove and handle, thus minimizing the risk of thermal runaway during the operator's handling.

[0057] In one example, one or more battery module components comprise a battery cell and / or a battery module hardware protection system.

[0058] In this way, the battery module may indicate the characteristics of the battery cells (or one or more battery cells) and / or the battery module hardware protection system. The battery module hardware protection system may include a fuse and / or a protection IC module, or may consist of a fuse and / or a protection IC module. This improves safety when replacing the above components.

[0059] In one example, the battery module includes a determination module configured to determine one or more parameters of a battery cell, determine the battery module component characteristics of the battery cell based on the one or more parameters, and provide an indication of the battery module component characteristics as an output.

[0060] In this way, the battery module component characteristics can be determined. The output of the decisionator module can be used as an input to indicate the battery module component characteristics. This is highly advantageous in that it allows the battery module itself to determine and indicate its own characteristics without being inserted into or connected to an aerosol generating device or any other device. This is useful when the battery module is, for example, a spare battery module that has not been used for a period of time, and the user wants to determine whether the battery module is suitable for use in an aerosol generating device. It should be understood that the decisionator module is provided as part of the battery module. This is in contrast to other methods, which may include, for example, providing the decisionator module elsewhere in the aerosol generating device, but not providing it as part of the battery module.

[0061] In one example, the battery module includes a visual indicator driver configured to provide a signal to the visual indicator based on the output of the determinator module.

[0062] In this way, the visual indicator can be driven or operated to provide the visual indicator to the user. Advantageously, the visual indicator driver can perform a comparison with a threshold. It can then drive an advantageous visual indicator, such as those described herein, to provide an intuitive and clear indication of the battery module component characteristics. It should be understood that the visual indicator driver is provided as part of the battery module. This is in contrast to other methods, such as providing the visual indicator driver elsewhere in an aerosol generating device, but not as part of the battery module.

[0063] In one example, a visual indicator is configured to receive signals from a visual indicator driver and provide an output that indicates the battery module component characteristics of the battery cell.

[0064] In this way, the characteristics of the battery module components can be communicated to the user.

[0065] In one example, a visual indicator may or may be an electrochromic display. That is, a battery module may have an electrochromic display. An electrochromic display may be able to operate with a small input power signal. An electrochromic display may have a memory latency to display information for a period of time after the power input is cut off. Advantageously, the power input required by an electrochromic display is small, meaning that continuous display of battery component characteristics can be achieved without substantially draining the battery unit. This means that visual indicators with electrochromic displays are highly power efficient. An electrochromic display may be flexible (e.g., formed from a flexible material) and may be mounted on and / or in various locations on various battery modules as needed. An electrochromic display may conform to the shape or surface of at least some part of the battery module. An electrochromic display is clear and visible in different light environments, such as ambient light, without requiring additional light-emitting elements. Advantageously, an electrochromic display is a low-power, flexible, and simple solution for displaying battery information.

[0066] The electrochromic display may receive signals from a visual indicator driver based on the output of the determinator module. The electrochromic display may be configured to provide an output display indicating the battery module component characteristics.

[0067] In one example, battery module component characteristics are the health state (SoH) of one or more battery module components, or the charge state (SoC) of one or more battery module components.

[0068] Informing users of the State of Home (SoH) is highly advantageous because it allows them to determine whether a battery module is suitable or safe for connection in an aerosol generating device (which may include whether it is suitable or safe for use in a particular use case). In particular, knowing the SoH of a battery module can allow users to select from several available battery modules or improve safety based on their requirements or specific use case. Informing users of the System of Chip (SoC) is highly advantageous because it allows them to determine whether a battery module is suitable or safe for connection in an aerosol generating device (which may include whether it is suitable or safe for use in a particular use case).

[0069] In one example, the visual indicator includes a fuse device comprising one or more fuses. In one example, the one or more fuses include one or more resettable fuses and / or one or more non-resettable fuses.

[0070] Advantageously, using fuse devices provides a low-power, robust, and simple solution for indicating the characteristics of battery module components. Resettable fuses allow for indicating the SoC, while non-resettable fuses can reduce manufacturing costs.

[0071] In one example, the fuse device is mounted on an organic substrate. In one example, the organic substrate includes a hydrophobic material.

[0072] Advantageously, the use of hydrophobic materials avoids excessive power consumption and minimizes fuse activation delays. Furthermore, power is not depleted due to the characteristics of the battery module components, thereby improving energy efficiency.

[0073] In one example, the visual indicator includes a lighting device comprising one or more light-emitting elements.

[0074] Advantageously, this allows for a clearer and more intuitive communication of battery module component characteristics to the user. Furthermore, the light-emitting element can facilitate indication of the SoC, which may increase and decrease throughout the charge / discharge cycle. When a single light-emitting element is used, this may allow for indication of battery module component characteristics above or below a threshold. Multiple light-emitting elements may provide a more detailed or stepwise indication of battery module component characteristics above or below multiple thresholds.

[0075] In one example, the light-emitting element includes one or more LEDs and / or OLEDs.

[0076] Advantageously, LEDs can be manufactured cost-effectively. Advantageously, OLEDs can provide flexible displays that can be wrapped around or conform to the shape of one or more battery module components, particularly battery cells.

[0077] In one example, the visual indicator includes a lighting device and a fuse device. Such a structure is easy to manufacture but also provides a robust, low-power means of indicating the characteristics of battery module components.

[0078] In one example, a battery cell characteristic indicator provides indications of the battery cell's charge level, degradation level, and / or expiration date.

[0079] In this way, information regarding decisions about removing and replacing the battery cells of an aerosol generating device can be provided to the user.

[0080] In one example, the visual indicator includes a chemical indicator of the battery cell charge level.

[0081] In this way, the charge level may be indicated to the operator without the use of an electronic display, thereby providing the operator with a more reliable output. Furthermore, the structure can be simplified by avoiding the need for additional electronic components. The visual indicator may include a chemical indicator of the battery cell voltage.

[0082] In one example, a visual indicator can be operated to provide indications of battery module component characteristics. A visual indicator may be operated by an operator to provide indications. In one example, a visual indicator can be operated by a trigger. In one example, the trigger is a button.

[0083] In this way, indications of battery module component characteristics can be provided only when desired by the operator. This improves the lifespan of the battery module components because they are not provided when characteristic indications are not needed. This is particularly advantageous when the battery module component is a battery cell, in which case indications of battery cell characteristics (e.g., charge level) can only be provided when the visual indicator is activated by the operator. Furthermore, by providing a trigger, the visual indicator can be operated to indicate battery module component characteristics only when desired or needed by the user, thereby reducing power consumption.

[0084] A visual indicator may be operable to form or complete an electrical circuit. A visual indicator may be a thermochromic indicator. A visual indicator may be operable by applying pressure to one or more contacts to form or complete an electrical circuit.

[0085] In one example, the battery module is located behind a cover assembly that includes a visibility assembly for viewing a visual indicator.

[0086] In this way, operators can be protected from contact with the battery module or its components in the assembled configuration, but the characteristics of the battery module components can still be monitored by viewing visual indicators through the visual assembly. In this way, the characteristics of the battery module components can be determined and monitored before disassembly. Thus, the safety of the disassembly process is improved.

[0087] In one example, the visual indicator is located on the outer surface of at least one of the battery module components.

[0088] Advantageously, this reduces the form factor of the battery module, thereby improving space efficiency.

[0089] According to a fifth aspect of the present invention, an aerosol generating device is provided that includes a battery module according to a fourth aspect of the present invention.

[0090] In this way, in an aerosol generating device, the operator can determine the characteristics of the battery module components by referring to the battery module, for example, by referring to the battery module itself or only the battery module. This is in contrast to existing examples of aerosol generating devices where the characteristics of the battery module components may be indicated to the operator by the aerosol generating device (or a system or a module other than the battery module), but not by the battery module itself. Because the operator only needs to refer to the battery module and not to other systems that may be provided in the aerosol generating device, this structure is highly advantageous in improving safety when disassembling the aerosol generating device and when replacing or recycling the battery module components. In this example, the battery module does not need to be provided as part of the aerosol generating device in order to provide or indicate the characteristics of the battery module components. In other words, the battery module can independently indicate the characteristics, or "status," of the battery module. This is highly advantageous in that it makes it possible to determine the characteristics of the battery module components, thereby facilitating the replacement or recycling of the battery module. Furthermore, the characteristics of the battery module components can be determined without or before insertion into the device. This allows users to decide whether or not a battery module is suitable for use in an aerosol generating device, meaning that users may decide not to use a battery module in some cases. This improves user convenience because users do not need to insert the battery module into the device to understand its characteristics.

[0091] A fifth aspect of the present invention may, if desired or as needed, include any or all features of any of the aspects introduced above.

[0092] A sixth aspect of the present invention provides a battery module for an aerosol generating device, comprising a plurality of battery module components, wherein the battery module components are connected by one or more flexible connectors.

[0093] This structure allows for the formation of connections between battery module components provided in different spaces or dispersed locations.

[0094] In one example, one or more flexible connectors are thin-film connectors.

[0095] Therefore, the use of available space in the aerosol generation device is optimized.

[0096] In one example, one or more flexible connections are electrical connections.

[0097] This makes it easier to form electrical connections between battery module components provided in different spaces or distributed locations.

[0098] In one example, a battery cell comprises multiple battery subcells.

[0099] Therefore, it becomes easier to incorporate a unique battery cell structure.

[0100] According to a seventh aspect of the present invention, an aerosol generating device is provided that includes a battery module according to a sixth aspect of the present invention.

[0101] A seventh aspect of the present invention may, if desired or as needed, include any or all features of any of the aspects introduced above.

[0102] According to an eighth aspect of the present invention, a method for installing a battery module in an aerosol generating device is provided, which includes operating one or more flexible connectors that connect battery module components to place the battery module in the aerosol generating device.

[0103] An eighth aspect of the present invention may, if desired or as needed, include any or all features of any of the aspects introduced above.

[0104] Here, an example of this disclosure will be described with reference to the attached drawings. [Brief explanation of the drawing]

[0105] [Figure 1] This is an exploded view of an aerosol generating device. [Figure 2] Figure 1 shows the assembled state of the aerosol generating device. [Figure 3] This shows the arrangement of connecting elements. [Figure 4] This shows a battery module for an aerosol generating device. [Figure 5] The general principles of the method are presented. [Figure 6] A perspective view of the battery module is shown. [Figure 7] A cross-sectional view of the aerosol generating device is shown. [Figure 8] The circuit diagram for the battery module is shown. [Figure 9] Figure 8 shows diagrams of the battery module under various conditions. [Figure 10] The circuit diagram for the battery module is shown. [Figure 11] Figure 10 shows diagrams of the battery module under various conditions. [Figure 12] This shows an aerosol generating device. [Figure 13] This shows an aerosol generating device. [Modes for carrying out the invention]

[0106] As used herein, the terms “aerosol precursor material,” “vapor precursor material,” or “vaporizable material” are used synonymously and may refer to materials and / or compositions that may contain, for example, nicotine or tobacco and a vaporizer. Aerosol precursor materials are configured to release an aerosol when heated or otherwise mechanically stimulated (e.g., by vibration). Tobacco may take the form of various materials such as shredded tobacco, granular tobacco, tobacco leaves, and / or reconstituted tobacco. Nicotine may be in the form of nicotine salts. Suitable vaporizers include polyols, e.g., sorbitol, glycerol, and glycols (e.g., propylene glycol or triethylene glycol), non-polyols, e.g., monohydric alcohols, acids (e.g., lactic acid), glycerol derivatives, esters (e.g., triacetin), triethylene glycol diacetate, triethyl citrate, glycerin, or vegetable glycerin. In some examples, the aerosol precursor material is substantially liquid that holds or contains one or more solid particles, such as tobacco. The aerosol generating device is configured to aerosolize an aerosol precursor material without combustion in order to facilitate the delivery of aerosols to the user. Furthermore, as is common in the art, the terms “vapor” and “aerosol,” as well as related terms such as “vaporize,” “volatilize,” and “aerosolize,” can generally be used interchangeably.

[0107] As used herein, the term “aerosol generation device” is synonymous with “aerosol generating device” or “device,” and may include a device configured to heat an aerosol precursor material and deliver an aerosol to a user. The device may be portable. “Portable” may mean a device that is intended to be used when held by a user. The device may be adapted to generate a variable amount of aerosol that can be controlled by user input.

[0108] As used herein, the term “aerosol” may include suspended matter of a vaporizable material as one or more solid particles, droplets, or gases. Such suspended matter may be in a gas, such as air. In general, an aerosol may refer to / include vapor. An aerosol may contain one or more components of a vaporizable material.

[0109] Referring to Figure 1, the aerosol generating device 100 is shown in an exploded side cross-sectional view. The aerosol generating device 100 is shown schematically, and only the details necessary to understand the relevant concepts described herein are shown in Figure 1. That is, several components used in aerosol generation may also be included in the aerosol generating device 100, but are not shown in Figure 1 for simplicity. A more detailed example of the aerosol generating device is shown in Figure 13. Those skilled in the art will understand that these details may be incorporated into the aerosol generating device 100.

[0110] The aerosol generating device 100 comprises a plurality of spaces 110a to c. Spaces 110a to c are defined by components 102 of the aerosol generating device 100.

[0111] The aerosol generating device 100 includes a battery module 120. The battery module 120 includes one or more battery module components 122. One or more battery module components 122 can be arranged in multiple spaces 110a to c.

[0112] Referring to Figure 2, the aerosol generating device is shown in its assembled state. One or more battery module components 122 are arranged in multiple spaces 110a to c.

[0113] This structure improves the use of available space within the aerosol generating device 100. Specifically, the spaces 110a-c defined by the components 102 (which may mean spaces between the components 102, or spaces defined by gaps between the components 102) are used to accommodate one or more battery module components 122. To put it simply, the spaces can also be considered "gaps" between the components 102, and these gaps are "filled" by placing battery module components 122 inside them.

[0114] Furthermore, since the battery module component 122 can be removed from the spaces 110a to c, the removal of the battery module component 122 becomes easier. Moreover, since a replacement battery module component can be installed in the spaces 110a to c, replacement is simpler and more intuitive. This is in contrast to existing methods in which the battery module component is inserted into an intrinsic, possibly separate location within the aerosol generating device 100, rather than into a space defined by the component that may be suitable (or may be specially designed or positioned) to receive the component. In this example, spaces 110a to c may be suitable (for example, may be specially designed or positioned) to receive one or more battery module components 122.

[0115] This structure also ensures that genuine replacement parts are used, as there is a requirement that the form factors of the replacement battery module components and the spaces 110a-c defined by component 102 "match".

[0116] The aerosol generating device 100 comprises an outer case 104 and an outer case cover 106. The outer case cover 106 can be connected to the outer case 104 to house components (such as a battery module 120) inside.

[0117] As described above, component 102 of the aerosol generating device 100 defines multiple spaces 110a to c. Component 102 may also be known as an aerosol generating device component or a system component. Component 102 may be something other than the battery module component 122.

[0118] Component 102 is positioned or installed in an appropriate manner within the aerosol generating device 100. Component 102 may be positioned to define spaces 110a-c (sometimes referred to as "gap"). Spaces 110a-c may be planned to accommodate or receive one or more battery module components internally. Alternatively, spaces 110a-c may be incidentally provided as a result of the positioning of component 102 within the aerosol generating device 100. Existing aerosol generating devices may have spaces defined by the components of the aerosol generating device, but existing methods do not properly utilize, or do not utilize, such spaces. Instead, many existing methods incorporate battery modules into a specific space specifically designed for battery modules, and this specific space may be a parallelepiped space. A key feature of the present invention is that such spaces can be used to position one or more battery module components 122 internally. This allows for more effective use of the available space in the aerosol generating device 100. An important feature is that one or more battery module components 122 are arranged in multiple spaces 110a to c, rather than in a single space as in conventional configurations. This makes it possible to utilize the available space provided by the multiple spaces within the aerosol generating device 100.

[0119] Furthermore, the battery module 120 may be detachably mounted on the aerosol generating device 100. In other words, the battery module 120 may be a removable battery module 120 (or "a battery module 120 that can be detachably mounted" or "a battery module 120 that is detachably mounted or provided on the aerosol generating device 100").

[0120] It is highly advantageous to provide a removable battery module 120, comprising battery module component 122, located within spaces 110a-c. Firstly, the removable battery module 120 may have one or more connections for forming releasable electrical and / or engaging connections with components of the aerosol generating device 100 (such as component 102) (this may include forming connections with the PCB of the aerosol generating device 100). This requires more space than soldered connections commonly found when the battery module is not removable. Utilizing spaces 110a-c improves the use of available space within the aerosol generating device 100. Furthermore, access to the connections is facilitated by utilizing spaces 110a-c. This facilitates the removal of the battery module 120 while simultaneously reducing the amount of disassembly work required on the aerosol generating device 100 to access and remove the battery module 120.

[0121] The battery module 120 may be connected to the aerosol generating device 100. The battery module 120 may be connected to at least one of the components 102 of the aerosol generating device 100. When the battery module 120 is placed in space 110a to c, an electrical connection may be formed between the battery module 120 and at least one of the components 102 of the aerosol generating device 100.

[0122] The electrical connection can be formed at a single point or location. That is, the battery module 120 may have an electrical connector, and the aerosol generating device may have a corresponding electrical connector for connecting to the electrical connector of the battery module 120. One of the battery module components 122 may have an electrical connector, or may be provided with an electrical connector, while the other battery module components may not have an electrical connector. The other battery module components may have connectors for forming mechanical connections with spaces 110a-c or components 102 of the aerosol generating device 100, but only a single electrical connection is required. Power can be supplied from the battery module 120 to the aerosol generating device 100 via the electrical connection. The battery module 120 may be electrically connected to the aerosol generating device 100 on the PCB of the aerosol generating device 100.

[0123] In one example, an insulator (not shown) is provided in a region or space between at least a portion of the battery module 120 and at least one of the spaces 110a to c. The insulator may be provided on or around one or more battery module components 122. This protects the components 102 of the aerosol generating device 100 from the battery module 120 and prevents, for example, electrical short circuits and / or overheating of the components 102 of the aerosol generating device 100 caused by the operation of the battery cells 124.

[0124] In one example, one or more battery module components 122 comprise a battery cell 124 and one or more additional battery module components. One or more additional battery module components comprise a battery module hardware protection system 126. The battery module hardware protection system 126 may comprise a fuse 126a and / or a protection integrated circuit (IC) module 126b. One or more additional battery module components may comprise an interface (e.g., a user interface).

[0125] In one example, one or more battery module components 122 are detachably arranged within multiple spaces 110a to c.

[0126] The associated advantages of such a structure should become clear from the above. Furthermore, in this way, individual components can be removed from spaces 110a-c and the aerosol generating device 100 for replacement and / or recycling.

[0127] In one example, multiple spaces 110a to c are defined by the printed circuit board 108 (PCB) and / or one or more casing portions of the aerosol generating device 100. One or more casing portions may be parts of the outer case 104 and / or parts of the outer case cover 106.

[0128] In one example, one or more battery module components 122 correspond to one of the spaces 110a to c. Spaces 110a to c may be specific spaces or may include specific spaces. The shape or size of one or more battery module components 122 may be determined to correspond to one of the spaces 110a to c.

[0129] In other words, each battery module component 122 may correspond to a specific space 110a to c. Each battery module component 122 may be an insertable component, and spaces 110a to c may be receptive spaces configured to accept insertable components.

[0130] In this way, spaces 110a-c provide a unique 3D pattern. This simplifies the replacement of battery modules 120, as only battery modules with the appropriate configuration can be inserted into and accepted in spaces 110a-c. This can be used to ensure that only genuine and / or suitable battery modules are used in the replacement process.

[0131] In one example, spaces 110a to 110c are provided or defined by multiple sections.

[0132] Each compartment is defined by the surface of a component of the aerosol generating device 100 and may include one of the spaces 110a to c.

[0133] The battery module 120 may be mountable or connectable to the surface of a compartment, for example, a compartment wall. That is, the battery module 120 or battery module component 122 may be mountable to a part of component 102 of the aerosol generating device 100. The mounting mechanism may be provided such that a first part of the mounting mechanism is provided on the battery module 120 and a second part of the mounting mechanism is provided on the compartment.

[0134] In one example, the aerosol generating device 100 includes a sensor device 132. The battery module 120 includes a first portion 132a of the sensor device 132, and a second portion 132b of the sensor device 132 is provided in at least one of a plurality of spaces 110a to c. The second portion 132b of the sensor device 132 may be provided within or on the surface of a compartment.

[0135] In the examples shown in Figures 1 and 2, the first portion 132a of the sensor device 132 is located on the battery cell 124. However, the first portion 132a of the sensor device 132 may be located on or elsewhere within the battery module 120, and the second portion 132b of the sensor device 132 may be located in the corresponding spaces 110a to 110c, so that these portions can work together to perform detection.

[0136] In one example, the second portion 132b of the sensor device 132 is configured to detect the first portion 132a of the sensor device 132.

[0137] In this way, proper insertion, engagement, and connection of the battery module into spaces 110a to c can be ensured.

[0138] In one example, the sensor device 132 includes a proximity sensor. The proximity sensor may be a Hall effect sensor.

[0139] In one example, the second portion 132b of the sensor device 132 is mounted on a battery module component 122 separate from the battery cell 124. In other words, the second portion 132b of the sensor device 132 is mounted on a battery module component 122 that is not the battery cell 124.

[0140] In this way, replacing only the battery cell 124 of the battery module 120 may be simpler and less expensive.

[0141] In one example, the sensor device provides or generates an output signal to authenticate the battery module and / or to ensure proper connection. The output signal may be a combination of signals.

[0142] In one example, the sensor device may comprise multiple sensors that can be positioned on or within different battery module components 122 and spaces 110a-c. That is, each battery module component 122 may comprise a first part of the sensor, and each space 110a-c may comprise a corresponding second part of the sensor. In this way, the output signal may be provided as a combination of signals from the multiple sensors, ensuring proper connection of each battery module component 122 in each space 110a-c.

[0143] In one example, the battery module 120 comprises multiple battery module components 122 connected to each other (i.e., connected together) by one or more connecting elements 140. The connecting elements 140 may be located outside of spaces 110a to c.

[0144] In other words, in one example, one or more connecting elements 140 connect battery module components 122 located in different spaces 110a to c. One or more connecting elements 140 may extend partially or completely outside spaces 110a to c between the components.

[0145] In this way, the connection of the separated battery module components 122 (for example, those located in different spaces 110a to c) can be achieved. This improves the use of space in the aerosol generating device 100, rather than requiring a single space where all components and connections must be housed.

[0146] One or more connection elements 140 may have one or more flexible connection parts, or may have one or more flexible connection parts. The flexible connection part may be a thin-film connection part or an electrical connection part. The flexible connection part may include layers of conductor and insulator arranged in parallel.

[0147] Referring to Figure 3, an exemplary arrangement of the connecting element 140 is shown.

[0148] Referring to Figure 3(a), a portion of the battery module 120 is shown. The connecting element 140 connects multiple battery module components 122. In the illustrated example, component 122 is a component of a battery module hardware protection system 126, which includes a fuse 126a and a protection IC module 126b.

[0149] The connecting element 140 comprises a layered, laminated, or stacked structure of a polyimide film 142 and a metal (e.g., steel or copper) conductive layer 144. The polyimide film 142 may be used in the formation of a flexible printed circuit. The connecting element 140 is flexible, allowing it to be bent or manipulated at sharp angles. This facilitates the connection of battery module components 122 located in spaces 110a-c. Furthermore, this simplifies the connection of components in aerosol generating devices having curved or rounded external shapes. The thin-film connecting section also requires less space in the aerosol generating device, thus enabling a reduction in the device's form factor and / or freeing up space for additional components.

[0150] Referring to Figure 3(b), an exemplary arrangement of connection elements 140a and 140b is shown. Connection elements 140a and 140b connect to both sides of the battery module component, specifically PCB 146. This configuration allows for narrow connections, such as electrical connections formed in narrow or limited spaces. Connection elements 140a and 140b connect to PCB 146 using flat tabs. The flat tabs allow for the conduction of large currents and simplify connection to the PCB.

[0151] Referring to Figures 3(c) and 3(d), further exemplary arrangements of connection elements 140c and 140d are shown. Connection elements 140c and 140d are connected to one side of the battery module component, specifically PCB 148. Connection elements 140c and 140d are connected to PCB 146 using flat tabs. The flat tabs allow for the conduction of large currents and simplify connection to the PCB.

[0152] Referring to Figure 4, a battery module 120 for the aerosol generating device 100 is schematically shown. The aerosol generating device 100 comprises a plurality of spaces 110a to c defined by the components of the aerosol generating device 100. The battery module 120 comprises one or more battery module components 122 that can be placed within the plurality of spaces 110a to c.

[0153] It should become clear that there are many advantages to providing only the battery module 120. The battery module 120 can be used to modify the aerosol generating device 100. It can improve the use of available space within the aerosol generating device 100. Furthermore, the battery module 120 can be easily replaced in the aerosol generating device 100 without completely disassembling the aerosol generating device.

[0154] Referring to Figure 5, a method for assembling the aerosol generating device is shown. Step S510 includes providing a battery module comprising one or more battery module components. Step S520 includes arranging one or more battery module components within a plurality of spaces defined by the components of the aerosol generating device.

[0155] Referring to Figure 6, a battery module for an aerosol generating device is shown.

[0156] In this example, the battery module in Figure 6 is the battery module 120 described above, and is for the aerosol generating device 100 described above. That is, the battery module 120 shown in Figure 6 may incorporate any or all of the features of the battery module 120 described above, as desired or as needed. However, in other examples, the battery module 120 shown in Figure 6 may be a different battery module from the one described above in relation to Figures 1 to 5, and its features are not required (i.e., may be absent), as will be understood by those skilled in the art. The battery module 120 may also be called a battery pack 120.

[0157] The battery module 120 comprises one or more battery module components 122. The battery module 120 also comprises a visual indicator 150. The visual indicator 150 is part of (or forms part of) the battery module 120. The visual indicator 150 is configured to display battery module component characteristics. The battery module component characteristics may be characteristics of one or more battery module components 122 (for example, characteristics of one of the components 122, or a combination of two or more battery module components 122, or characteristics of the entire battery module 120).

[0158] As introduced above, the visual indicator 150 is part of the battery module 120. This is in contrast to examples of conventional aerosol generators where the visual indicator can be incorporated into the aerosol generator but not into its battery module. This is a minor but important difference. In one example, in a conventional aerosol generator, an indication of the battery cell charge level may be provided to the user of the aerosol generator using the user interface of the aerosol generator. The user interface may be connected to a controller or processor that does not form part of the battery module. However, in the present invention, it has been found to be very advantageous to incorporate a visual indicator of the battery module component characteristics into the battery module 120 itself when replacing the battery module 120. In this way, important information about the battery module 120 or its components can be provided to the user without (or before) connection to the aerosol generator 100. As a result, the user can decide whether or not to connect a particular battery module 120 to the aerosol generator 100 based on the above information. This decision may be based on the battery module component characteristics, including whether the user considers the health or charge state of the battery module 120 to be suitable for connection to the aerosol generator 100. Furthermore, if multiple battery modules 120 are available to the user for connection to or supplying to the aerosol generating device 100, the user may be able to make their own decision on which battery module to use with the aerosol generating device 100 based on the characteristics of the battery module components, which are provided to the user via a visual indicator 150.

[0159] If provided in an aerosol generating device, the visual indicator 150 may be provided in addition to a user interface (e.g., a standard user interface) configured to indicate battery module component characteristics. The user interface may receive signals from the processor of the aerosol generating device (the processor is connected to the battery module 120).

[0160] In other words, the visual indicator 150 is specific to the battery module 120. While conventional devices may incorporate visual indicators in the form of battery charge level displays, it should be understood that such prior art indicators are not provided on (or do not form part of) the battery module. The visual indicator 150 may be operable to indicate battery module component characteristics when the battery module 120 is disconnected from the aerosol generating device 100 (i.e., when the battery module 120 is provided separately).

[0161] In one example, the battery module 120 comprises one or more connection elements 140. One or more connection elements 140 connect to or can connect to one or more battery module components 122. One or more connection elements 140 comprises a visual indicator 150. In an alternative example, the visual indicator 150 may be located elsewhere within the battery module 120, as will be described in more detail below in relation to Figures 8 to 11.

[0162] The connection element 140 may provide an electrical connection within the battery module 120. In this way, one or more connection elements 140 provide a dual function, in that they serve both as an electrical connection and as a visual indicator of the battery module component characteristics. Advantageously, the visual indicator 150 provided on the connection element 140 allows for the determination of characteristics while also improving the utilization of available space within the battery module 120 and the aerosol generating device 100. The connection element may be a thin-film connection as described above.

[0163] In one example, the battery module component characteristics relate to the operation of one or more battery module components 122.

[0164] The operation may include supplying power from the battery module 120 to the aerosol generating device 100. In addition, the operation of one or more battery module components 122 may be the electrical operation of one or more battery module components 122, and the characteristics may represent the electrical operation. In this way, the operator can determine whether the battery module components 122 are operating correctly and will continue to operate correctly.

[0165] In one example, the battery module component characteristics relate to the electrical state of one or more battery module components 122.

[0166] The electrical state may be the charge state or voltage of one or more battery module components 122.

[0167] The electrical state could be the current charge level or voltage of the battery cell 124. In this way, the operator can ensure that the battery cell 124 is discharged and safe to remove and handle, thus minimizing the risk of thermal runaway during the operator's handling.

[0168] In one example, one or more battery module components 122 include battery cells 124 and / or a battery module hardware protection system 126.

[0169] The battery module component characteristics may be the charge level of the battery cell 124. Additionally or alternatively, the battery module component characteristics may be reference or identification information for the battery module component 122 of the battery cell 124 or for the entire battery module 120. The battery module component 122 may be the battery cell 124, and the battery module component characteristics may be an indication of the expiration date or degradation level of the battery cell 124. In this way, the operator can determine that a battery cell needs to be replaced by referring to the visual indicator 150 of the battery module 120, rather than by referring to the user interface of the aerosol generating device 100.

[0170] Furthermore, in this manner, the battery module 120 can indicate the characteristics of the battery cell 124 and / or the battery module hardware protection system 126 (via the visual indicator 150). The battery module hardware protection system 126 may include a fuse 126a and / or a protection IC module 126b, or it may include a fuse 126a and / or a protection IC module 126b. This improves safety when replacing the above components.

[0171] In one example, the visual indicator 150 provides indications of the charge level of the battery cell 124, the degradation level of the battery cell 124, and / or the expiration date of the battery cell 124.

[0172] By indicating the charge level of battery cell 124, the operator can confirm that battery cell 124 is discharged and therefore safe to handle during removal and replacement. Furthermore, by indicating the degradation level and / or expiration date of battery cell 124, it may be possible to determine that battery cell 124 should be replaced. The degradation level may indicate the relative level of safety, reliability, or performance of battery cell 120 (for example, compared to a new battery cell 120).

[0173] In one example, the visual indicator 150 includes a chemical indicator of the battery cell charge level. The chemical indicator may be a thermochromic indicator of the battery cell charge level. In this way, it becomes unnecessary to require electronic means to indicate the characteristics of the battery cell module components. This may be well suited to a replacement process performed by an operator, in contrast to conventional devices that have electronic means to indicate characteristics such as the battery charge level to the user via a more intuitive electronic display.

[0174] In one example, the visual indicator 150 can be operated to provide indication of the battery cell module component characteristics.

[0175] The visual indicator may be operable by applying pressure to one or more contacts to form or complete an electrical circuit. In this way, the visual indicator may be provided only when the operator wishes to determine the characteristics of the battery cell module components. This may extend the life of the battery cell 124 or preserve its charge.

[0176] Referring to Figure 7, the battery module 120 is shown positioned within the aerosol generating device 100. In one example, the battery module 120 is located behind a cover assembly 160 that includes a viewing assembly 162 for viewing a visual indicator 150.

[0177] In this way, the battery module 120, specifically the battery cells 124, is shielded from the operator during the replacement process, while the operator can determine whether the battery module 120 can be handled safely (due to being discharged) or whether replacement of the battery module 120 is necessary (due to degradation level or expiration date).

[0178] The visibility assembly 162 may have a slot in the cover assembly 160. The visual indicator 150 may be visible through the slot. The visibility assembly 162 may include the slot and a transparent or translucent material member provided within the slot through which the visual indicator 150 is visible. The slot may also be known as an opening.

[0179] Referring to Figure 8, a circuit diagram of the battery module 120 is shown. The battery module 120 is substantially the same as described above in relation to Figures 6 and 7. In Figures 6 and 7, the visual indicator 150 is shown to be provided on the connection element 140, but in the battery module 120 shown in Figures 8 and 9, the visual indicator may be provided elsewhere on the battery module 120, or may actually be provided on the connection element 140 as described above. Further features of the battery module 120 will be described in relation to Figure 8.

[0180] As described above, the battery module 120 is for the aerosol generating device 100. As shown in Figures 8 and 10, the battery module 120 may be connected to the aerosol generating device 100 to supply power to the aerosol generating device 100 by battery module terminals (or pads) 121a, 121b. Terminal 121a may be the positive terminal and terminal 121b may be the negative terminal.

[0181] Referring to Figure 8, the battery module 120 comprises one or more battery module components 122. In particular, the battery module 120 comprises a battery cell 124. The battery cell 124 may be a rechargeable battery cell 124. The battery module 120 comprises a visual indicator 150. The visual indicator 150 is configured to indicate the characteristics of the battery module components.

[0182] As will be explained in more detail below, in one example, the battery module component characteristics may be the state of health (SoH) of the battery module component 122. Indicating the SoH to the user is very advantageous as it allows for the determination of whether the battery module 120 is suitable for connection in the aerosol generating device 100. The SoH of a battery cell is well known in the relevant art. SoH is a performance index of the battery's state compared to its ideal state. Over time, the SoH of a battery decreases due to repeated charging cycles and use of the battery cell. The state of health can be defined as the ratio of the maximum battery charge (e.g., at the present time) to its rated capacity (e.g., as new), and can be expressed as a percentage.

[0183] In one example, the battery module 120 includes a decision module 202. The decision module 202 is configured to determine one or more parameters of the battery cell 124. The decision module 202 is configured to determine the battery module component characteristics of the battery cell 124 based on one or more parameters. In other words, in a very favorable example, the decision module 202 is configured to determine the State of Height (SoH) of the battery cell 124 based on one or more parameters.

[0184] The determinator module 202 may form part of a battery module component characterization system, which may be interchangeably referred to as a "battery cell health state determination system" or "battery cell health determination system."

[0185] One or more parameters of the battery cell 124 may be one or more of the following: internal resistance / impedance / conductance, capacity, voltage, self-discharge, charge acceptance capacity, number of charge-discharge cycles, years of service of the battery cell, temperature of the battery cell during previous use or service cycles, and total energy charged and discharged. The parameters may be used individually or in combination. When used in combination, the parameters may be weighted or biased for each parameter's contribution to the SoH value.

[0186] As described above, the decision module 202 is configured to determine one or more parameters of the battery cell 124. This may be done by having one or more parameters of the battery cell 124 provided to the decision module 202 from one or more other components of the battery module 120, for example, from a processor or controller. Alternatively or additionally, this may be done by the decision module 202 determining one or more parameters of the battery cell 124 by measurement.

[0187] To measure one or more parameters of the battery cell 124, the determination module 202 may include a measurement module (not shown). The measurement module may be configured to measure one or more electrical loads of the battery cell 124. The measurement module may be configured to provide the measured values ​​of one or more electrical loads of the battery cell 124 as an output. The determination module 202 may be configured to determine the battery module component characteristics of the battery cell 124 based on the output of the measurement module.

[0188] The decision-maker module 202 is configured to provide an indication of the battery module component characteristics as an output. In a very advantageous example, the decision-maker module 202 is configured to provide the State of Heat (SoH) of the battery cell 124 or an indication thereof (e.g., an electrical signal of a specific voltage or current) as an output.

[0189] In one example, the battery module 120 includes a visual indicator driver 206. The visual indicator driver 206 is configured to provide a signal to the visual indicator 150 based on the output of the determinator module 202. In this way, the visual indicator 150 can be controlled to provide an indication of the battery module component characteristics (e.g., the State of Height of the battery cell 124) for visual indication to the user.

[0190] The visual indicator driver 206 may take the form of a comparator unit 206. The comparator unit 206 may include an interface (not shown). The interface may be configured to compare the output of the determinator module 202 with a threshold. The interface may be configured to provide an output based on the comparison between the output of the determinator module 202 and the threshold. The signal provided from the visual indicator driver 206 to the visual indicator 150 may be based on the output of the interface.

[0191] In one example, the visual indicator 150 is configured to receive signals from the visual indicator driver 206. The visual indicator 150 is configured to provide an output that indicates (or is intended to indicate) the battery module component characteristics of the battery cell 124. In this way, the battery module component characteristics can be indicated to the user, thereby enabling a rapid determination of the battery module component characteristics of the battery module 120. Even more advantageously, this determination can be made without installing (or connecting) the battery module 120 in the aerosol generating device 100.

[0192] In one example, the visual indicator 150 may or may be one or more electrochromic displays. That is, the battery module 120 may be one or more electrochromic displays. The electrochromic displays are configured to provide output indicators that indicate the battery module component characteristics.

[0193] Each of the one or more electrochromic displays may be configured to indicate different types of battery module component characteristics. Examples of battery module component characteristics may include one or more of the following: remaining stick count, recycle indicator, number of possible additional sessions when ECO mode is activated, charge indicator, health status, etc.

[0194] Each electrochromic display can be configured to operate independently, allowing it to indicate different battery module component characteristics in response to its respective trigger signal. Alternatively, multiple electrochromic displays can be activated together in response to a single trigger signal to simultaneously display various battery module component characteristics.

[0195] Electrochromic displays can operate with small input power signals. Electrochromic displays have memory latency to display information for a certain period after power input is cut off. Advantageously, the power input required by electrochromic displays is small, meaning that continuous display of battery component characteristics can be achieved without substantially draining the battery unit. This means that the visual indicator 150 with an electrochromic display is highly power-efficient. Electrochromic displays are clear and visible in different lighting environments, such as ambient light, without requiring additional light-emitting elements. Advantageously, electrochromic displays are a low-power, flexible, and simple solution for displaying battery information.

[0196] In embodiments comprising an electrochromic display, a battery module component characterization system configured to determine one or more parameters / characteristics of a battery module is located on the aerosol generating device and functions as a “host system”. The host system can calculate various battery module component characteristics and output this information to a visual indicator driver (MCU), which is configured to control the electrochromic display accordingly.

[0197] In one example, the electrochromic display can be integrated with the MCU. This configuration eliminates the need for separate memory to store the latest readings, as the most recent readings of the battery unit can be displayed on the electrochromic display. In addition, it facilitates a method for easily indicating the remaining charge of the battery unit during the charging process (such as a wireless charging process). In this example, the electrochromic display can continue to display information when the host system is disconnected. When the host system is reconnected, the display can display information without the need to synchronize or receive information from an external source such as the cloud. In this example, the electrochromic display can indicate to the user whether the battery unit is disconnected from the aerosol generating device.

[0198] The electrochromic display may receive signals from the visual indicator driver 206 based on the output of the determinator module 202. The electrochromic display may be configured to provide an output display indicating the battery module component characteristics.

[0199] In one example, the battery module component characteristics relate to the state of health (SoH) of one or more battery module components 122. The advantages of SoH indication should be understood from the above. Additionally or alternatively, the battery module component characteristics are the state of charge (SoC) of one or more battery module components 122. Indicating the SoC in the manner described is highly advantageous because it allows the user to determine the SoC without installing (or connecting) the battery modules 120 to the aerosol generating device 100.

[0200] In one example, the visual indicator 150 includes a fuse device 212, which is shown in Figures 8 and 9. The fuse device 212 comprises one or more fuses 212a, 212b, 212c, and 212d. A single fuse may be able to indicate battery module component characteristics that are above or below a threshold. Multiple fuses may provide more detailed indications of battery module component characteristics that are above or below multiple thresholds. Advantageously, using a fuse device 212 as described herein is a low-power, robust, and simple solution for indicating the State of Heat (SoH) of the battery cell 124.

[0201] The visual indicator driver 206 may indicate the State of Heat (SoH) of the battery cell 124 by providing the visual indicator 150 with a signal to blow or trip one or more fuses in the fuse device 212, based on the output of the decision-maker module 202. In other words, the visual indicator driver 206 may provide a signal to the visual indicator 150 based on the values ​​of the battery module component characteristics determined by the decision-maker module 202. The values ​​of the battery module component characteristics may be determined against a threshold.

[0202] Figure 9 shows the various states of the fuse device 212.

[0203] In the state shown in Figure 9(a), the decision module 202 determines that the SoH of battery cell 124 is greater than 80% (e.g., 90%). The visual indicator driver 206 may compare the determined SoH value with a threshold. The visual indicator driver 206 does not provide a signal to the visual indicator 150 so as not to blow any fuses, as shown in Figure 9(a). In this way, if no fuses blow, the visual indicator 150 provides an indication that the SoH of battery cell 124 is greater than 80%.

[0204] In the state shown in Figure 9(b), the determinator module 202 determines that the SoH of the battery cell 124 is greater than 60% but less than 80% (e.g., 70%). The visual indicator driver 206 may compare the determined SoH value to a threshold. The visual indicator driver 206 signals the visual indicator 150 to blow one fuse 212a, as shown in Figure 9(b). In this way, when one fuse 212a blows, the visual indicator 150 provides an indication that the SoH of the battery cell 124 is greater than 60% but less than 80%.

[0205] In the state shown in Figure 9(c), the determinator module 202 determines that the SoH of the battery cell 124 is greater than 40% but less than 60% (e.g., 50%). The visual indicator driver 206 may compare the determined SoH value to a threshold. The visual indicator driver 206 signals the visual indicator 150 to blow two fuses 212a, 212b (or one additional fuse 212b compared to Figure 9(b)), as shown in Figure 9(c). In this way, if two fuses 212a, 212b are blown, the visual indicator 150 provides an indication that the SoH of the battery cell 124 is greater than 40% but less than 60%.

[0206] In the state shown in Figure 9(d), the decision module 202 determines that the SoH of the battery cell 124 is greater than 20% but less than 40% (e.g., 30%). The visual indicator driver 206 may compare the determined SoH value to a threshold. The visual indicator driver 206 signals the visual indicator 150 to blow the three fuses 212a, 212b, and 212c (or one additional fuse 212c for Figure 9(c)), as shown in Figure 9(d). In this way, when the three fuses 212a, 212b, and 212c are blown, the visual indicator 150 provides an indication that the SoH of the battery cell 124 is greater than 20% but less than 40%.

[0207] In the state shown in Figure 9(e), the determinator module 202 determines that the SoH of battery cell 124 is greater than 0% but less than 20% (e.g., 10%). The visual indicator driver 206 may compare the determined SoH value to a threshold. The visual indicator driver 206 signals the visual indicator 150 to blow the four fuses 212a, 212b, 212c, and 212d (or one additional fuse 212d for Figure 9(d)), as shown in Figure 9(e). In this way, when the four fuses 212a, 212b, 212c, and 212d are blown, the visual indicator 150 provides an indication that the SoH of battery cell 124 is less than 20%.

[0208] Based on the instructions from the visual indicator 150, the user can decide whether or not to use a particular battery module 120 with the aerosol generating device 100. For example, a battery module 120 with battery cells 124 having a low SoH value (e.g., less than 20% or less than 40%) may not be suitable for a particular use case.

[0209] While threshold percentages of 80%, 60%, 40%, and 20% were described above, it should be understood that other threshold percentages may be used. Furthermore, it should be understood that the visual indicator 150 may be provided with fewer or more fuses. For example, a single fuse may be used, which may blow when the SoH of battery cell 124 is less than 10%, less than 20%, less than 30%, less than 40%, or less than 50%. The more fuses there are, the more stepwise indication of the SoH of battery cell 124 may be possible.

[0210] The fuses may be configured to blow sequentially, such that fuse 212a blows first, followed by fuse 212b, and so on. Advantageously, this improves the ease with which the battery module component characteristics are communicated to the user and their interpretation.

[0211] Each fuse in the fuse device 212 may be formed from a conductive material, of which copper alloys and / or aluminum alloys are favorable examples. The fuse resistance is low so that the fuse can blow quickly with a small power (e.g., on the order of a few mW).

[0212] One or more fuses 212a to d may include one or more resettable fuses. In this way, the SoC may be indicated. Unlike SoH, the SoC may rise when charging power is supplied to the battery cell 124 and fall when the battery cell 124 is depleted by drawing current from the battery cell 124. One or more fuses 212a to d may additionally or alternatively include one or more non-resettable fuses. In this way, the SoH may be indicated to the user in a state where manufacturing is less expensive.

[0213] In the manufacture of the battery module 120, a battery cell 124 is provided. The battery cell 124 may be provided with a substrate 214 that partially or completely surrounds, covers, or is provided on the battery cell 124. The substrate 214 is shown in Figure 9. The substrate 214 may be a shrink wrap substrate. One or more battery module components may be provided on the substrate 214, which may include protective and monitoring electronic equipment including a determiner module 202, a visual indicator driver 206, a fuse device 212, and / or other electronic components.

[0214] In one example, the fuse device 212 is provided on a substrate 214. In an advantageous example, the substrate 214 is an organic substrate 214. The organic substrate 214 may be formed from a hydrophobic material (for example, it may be formed entirely or partially). Advantageously, the use of a hydrophobic material avoids excessive power consumption and minimizes delay in fuse activation. Advantageous materials include hydrophobic treated pulp and / or polylactide (PLA). The hydrophobic material may be provided in the area of ​​the fuse device 212, or the fuse device 212 may be provided in the area of ​​the substrate 214 formed from the hydrophobic material. The thickness and / or thermal mass of the organic substrate can be kept relatively low so that it evaporates rapidly when the fuse of the fuse device 212 blows. In this way, holes or indicators of blown fuses may remain on the substrate 214, which advantageously improves readability.

[0215] As shown in Figure 8, the battery module 120 may further comprise a battery module hardware protection system 126, which may also be called a protection circuit module 126. The battery module hardware protection system 126 may be as described elsewhere in this specification. The battery module hardware protection system 126 is configured to provide protection to the battery cell 124 against overheating, supplying current exceeding a safe level, overcharging, over-discharging, and short circuits.

[0216] Referring to Figure 10, the circuit diagram of the battery module 120 is shown. The battery module 120 is substantially identical to the one shown and described in relation to Figure 8, with the following differences. The same reference numbers are used to indicate similar features.

[0217] In contrast to the battery module 120 in Figures 8 and 9, which includes a fuse device 212, the visual indicator 150 instead includes a lighting device 230. The lighting device is shown in Figures 10 and 11. The lighting device 230 includes one or more light-emitting elements 232a, 232b, 232c, and 232d. Advantageously, in this way, battery module component characteristics can be communicated to the user more clearly and / or intuitively. Furthermore, the light-emitting elements 232 can facilitate indication of the SoC, which may increase and decrease throughout the charge / discharge cycle. When a single light-emitting element is used, this may allow indication of battery module component characteristics above or below a threshold. Multiple light-emitting elements may provide more detailed or stepwise indication of battery module component characteristics above or below multiple thresholds.

[0218] As described above, the visual indicator driver 206 may provide a signal to the visual indicator 150 based on the output of the determinator module 202. The provided signal may cause the lighting device 230 to operate to indicate the State of Heat (SoH) of the battery cell 124. This may be done by operating the light-emitting element 232 of the lighting device 230 to provide light output, no light output, or light output of a specific color.

[0219] Figure 11 shows the various states of the lighting device 230.

[0220] In the state shown in Figure 11(a), the decision module 202 determines that the SoH of the battery cell 124 is greater than 80% (e.g., 90%). The visual indicator driver 206 may compare the determined SoH value with a threshold. The visual indicator driver 206 signals the visual indicator 150 to cause all light-emitting elements 232 to emit green light. In this way, the visual indicator 150 indicates that the SoH of the battery cell 124 is greater than 80% when all light-emitting elements 232 are emitting green light.

[0221] In the state shown in Figure 11(b), the determinator module 202 determines that the SoH of the battery cell 124 is greater than 60% but less than 80% (e.g., 70%). The visual indicator driver 206 may compare the determined SoH value to a threshold. The visual indicator driver 206 signals the visual indicator 150 to cause one light-emitting element 232a to emit red light. In this way, when one light-emitting element 232a emits red light, the visual indicator 150 indicates that the SoH of the battery cell 124 is greater than 60% but less than 80%.

[0222] In the state shown in Figure 9(c), the determinator module 202 determines that the SoH of the battery cell 124 is greater than 40% but less than 60% (e.g., 50%). The visual indicator driver 206 may compare the determined SoH value to a threshold. The visual indicator driver 206 signals the visual indicator 150 so that the two light-emitting elements 232a and 232b emit red light. In this way, the visual indicator 150 provides an indication that the SoH of the battery cell 124 is greater than 40% but less than 60%.

[0223] In the state shown in Figure 9(d), the determinator module 202 determines that the SoH of the battery cell 124 is greater than 20% but less than 40% (e.g., 30%). The visual indicator driver 206 may compare the determined SoH value with a threshold. The visual indicator driver 206 signals the visual indicator 150 so that the three light-emitting elements 232a, 232b, and 232c emit red light. In this way, the visual indicator 150 provides an indication that the SoH of the battery cell 124 is greater than 20% but less than 40%.

[0224] In the state shown in Figure 9(e), the determinator module 202 determines that the SoH of the battery cell 124 is greater than 0% but less than 20% (e.g., 10%). The visual indicator driver 206 may compare the determined SoH value to a threshold. The visual indicator driver 206 signals the visual indicator 150 so that the four light-emitting elements 232a, 232b, 232c, and 232d emit red light. In this way, the visual indicator 150 provides an indication that the SoH of the battery cell 124 is less than 20%.

[0225] Based on the instructions from the visual indicator 150, the user can decide whether or not to use a particular battery module 120 with the aerosol generating device 100. For example, a battery module 120 with battery cells 124 having a low SoH value (e.g., less than 20% or less than 40%) may not be suitable for a particular use case.

[0226] It should be understood that similar instructions may be provided by the visual indicator driver 206, which drives the lighting device 230 to cause a specific light-emitting element 232 to emit or not emit light. In addition, a single light-emitting element 232 may be used and controlled to emit a specific color indicating the State of Heat (SoH) of the battery cell 124.

[0227] While threshold percentages of 80%, 60%, 40%, and 20% were described above, it should be understood that other threshold percentages may be used. Furthermore, it should be understood that the visual indicator 150 may be provided with fewer or more light-emitting elements 232. For example, a single light-emitting element may be used, and this single element may operate to emit light when the SoH of the battery cell 124 is less than 10%, less than 20%, less than 30%, less than 40%, or less than 50%. The more light-emitting elements 232 there are, the more stepwise indication of the SoH of the battery cell 124 may be possible.

[0228] The light-emitting elements can be configured to operate sequentially. That is, light-emitting element 232a may light up first, followed by element 232b, and so on. Advantageously, this improves the ease of informing the user of the battery module component characteristics and their interpretation.

[0229] In the manufacture of the battery module 120, a battery cell 124 is provided. The battery cell 124 may be provided with a substrate 214 that partially or completely surrounds, covers, or is provided on the battery cell 124. The substrate 214 is shown in Figure 11. The substrate 214 may be a shrink wrap substrate. One or more battery module components may be provided on the substrate 214, which may include protective and monitoring electronic equipment including a determiner module 202, a visual indicator driver 206, a lighting device 230, and / or other electronic components.

[0230] The light-emitting element 232 includes one or more LEDs and / or OLEDs. Advantageously, LEDs can be easily manufactured cost-effectively. Advantageously, OLEDs can be wrapped around the battery cell 124 or provide a flexible display that conforms to the shape of the battery cell 124.

[0231] In one example, the battery module 120 includes a trigger 234. The trigger may be operated to trigger or initiate a determination of battery module component characteristics and / or an instruction of battery module component characteristics. This may be advantageous in reducing power consumption. The trigger 234 may be in the form of a button or a "check button." That is, the visual indicator 150 may be activatable by the trigger 234. Additionally or alternatively, the trigger 234 may be operated to deactivate the visual indicator 150.

[0232] As shown in Figure 10, the battery module 120 may further comprise a battery module hardware protection system 126, which may also be called a protection circuit module 126. The battery module hardware protection system 126 may be as described elsewhere in this specification. The battery module hardware protection system 126 is configured to provide protection to the battery cell 124 against overheating, supplying current exceeding a safe level, overcharging, over-discharging, and short circuits.

[0233] From the examples in Figures 8 to 11 and the above description, it should be understood that the visual indicator 150 may be provided on the outer surface of at least one of the battery module components 122. In an advantageous example, as also shown, the visual indicator 150 may be provided on the outer surface of the battery cell 124. Advantageously, this may reduce the form factor of the battery module 120, thereby improving space efficiency.

[0234] Referring to Figure 12, an aerosol generating device 100 is shown. The aerosol generating device 100 comprises a battery module 120. The battery module 120 may be a battery module 120 as illustrated and described in relation to Figures 6 to 11. That is, the battery module 120 comprises one or more battery module components 122, and the battery module 120 comprises a visual indicator 150 as part of the battery module 120, and the visual indicator 150 is configured to indicate the characteristics of the battery module components.

[0235] The advantages of such a structure are numerous and should be understood from the explanation provided herein.

[0236] In one example, the aerosol generating device 100 may include a cover assembly 160 with a viewing assembly 162 for viewing a visual indicator 150 of the battery module 120.

[0237] Figure 13 shows a schematic cross-sectional view of the aerosol generating device 100.

[0238] The aerosol generating device 100 may be any of the aerosol generating devices 100 described above. That is, the aerosol generating device 100 described in relation to Figure 13 may incorporate any or all of the above-described features as desired or as needed.

[0239] The aerosol generating device 100 is suitable for receiving consumables 1002 internally. For example, the aerosol generating device 100 may include a chamber 1004 in which the consumables 1002 are received.

[0240] The present invention is not limited to the specific aerosol generating device 100 or consumable 1002 described herein. That is, the descriptions of the aerosol generating device 100 and consumable 1002 are provided for illustrative purposes only. Those skilled in the art will understand that alternative structures of the aerosol generating device and consumable are suitable for the present invention.

[0241] Consumable 1002 comprises an aerosol substrate. The term aerosol substrate is a label used to mean a medium that generates an aerosol or vapor when heated. An aerosol substrate may be interpreted as an aerosol precursor. In one example, an aerosol substrate is synonymous with smokeable material, aerosol generating substrate, and aerosol generating medium. An aerosol substrate contains a material that provides volatile components when heated, usually in the form of vapor or aerosol. An aerosol substrate may be a non-tobacco-containing material or a tobacco-containing material. An aerosol substrate may contain, for example, one or more of the following: tobacco itself, tobacco derivatives, puffed tobacco, reconstituted tobacco, tobacco extract, homogenized tobacco, or tobacco substitutes. An aerosol substrate may also contain other non-tobacco products, which may or may not contain nicotine, depending on the product. An aerosol substrate may contain one or more humectants, such as glycerol or propylene glycol.

[0242] The aerosol generating device 100 may include one or more heaters 1006 configured to provide heat to the consumables 1002 during use.

[0243] In one example, the consumable 1002 contains a liquid, and one or more heaters comprise a heating element such as a coil, ceramic heater, plane resistance heater, mesh heater, or MEMS heater, configured to aerosolize the liquid for inhalation. Liquid delivery elements or mechanisms such as porous materials, capillary systems, and / or valves may transfer the liquid to the heating element during use. In some examples, the aerosolized liquid may pass through a solid substrate within the aerosol generating device 100. In other examples, the consumable 1002 may comprise a solid aerosol substrate.

[0244] In one example, the aerosol generating device 100 includes a spray engine such as a vibrating mesh that generates an aerosol from a liquid with or without heating.

[0245] The aerosol generating device 100 may include a mouthpiece 1012 for the user to inhale the generated aerosol by drawing the aerosol generating device 100 into it. The mouthpiece 1012 includes a vent or channel 1014 connected to an area close to the consumable 1002 to allow any generated aerosol from the consumable 1002 to pass through during use. For example, the channel 1014 may extend between an opening in the mouthpiece 1012 and a chamber 1004 capable of at least partially receiving the consumable 1002. The mouthpiece 1012 is configured to be received in the user's mouth during use. In other examples, the mouthpiece 1012 is not required, and a portion of the consumable 1002 may protrude from the aerosol generating device 100. In this example, the protruding portion of the consumable 1002 may function as a mouthpiece.

[0246] The aerosol generating device 100 may include a control unit 1008 (or control circuit) for electronically managing the device. The control unit 1008 may include a PCB or the like (not shown). The control unit 1008 is configured to control one or more heaters 1006.

[0247] The aerosol generating device 100 may include an activation input sensor 1018. The activation input sensor 1018 may be a button, touchpad, or the like for detecting user input such as taps or swipes. In another example, the activation input sensor 1018 may include a consumable sensor configured to detect whether a consumable 1002 has been inserted into the aerosol generating device 100. For example, the input sensor 1018 may include an authenticity detector configured to detect whether a genuine consumable 1002 has been inserted into the aerosol generating device 100. Additionally or alternatively, user input may also include inhalation by the user.

[0248] The aerosol generating device 100 may include a puff sensor 1020 (also known as an inhalation sensor). The puff sensor 1020 is configured to detect an inhalation action (i.e., a puff) by the user in the aerosol generating device 100. In one example, the puff sensor 1020 comprises a microphone or flow sensor configured for the airflow within the chamber 1004 and / or an airflow channel extending from the chamber 1004 through the mouthpiece 1012 to its inhalation outlet, where the airflow is related to the user's inhalation action. In another example, the puff sensor 1020 is configured to detect a change in pressure that signals the initiation of an inhalation action by the user in the aerosol generating device 100. In this case, the puff sensor 1020 can be located anywhere on the aerosol generating device 100 where a change in pressure occurs due to the user's inhalation action. In one example, the puff sensor 1020 is located in the channel 1014 between the chamber 1004 and the mouthpiece 1012 of the aerosol generating device 100. The puff sensor 1020 can also detect the end of the user's inhalation action. For example, the puff sensor 1020 may be configured to detect further changes in pressure resulting from the user's cessation of the inhalation action.

[0249] The aerosol generating device 100 may include one or more temperature sensors 1022 configured to directly or indirectly measure the temperature of the consumable 1002 in the aerosol generating device 100. The one or more temperature sensors 1022 may include thermocouples or thermistors, etc., configured to be positioned within or adjacent to the consumable 1002 when the consumable 1002 is received into the aerosol generating device 100. For example, one or more temperature sensors 1022 may be positioned within the chamber 1004 of the aerosol generating device 100. In another example, the temperature of the consumable 1002 may be measured indirectly by the use of a thermal imaging sensor. In yet another example, if the heater 1006 has PTC (positive temperature coefficient) or NTC (negative temperature coefficient) characteristics, the heater 1006 itself functions as a temperature sensor.

[0250] The aerosol generating device 100 may include a power source 1050, such as a battery cell. The power source 1050 may be the battery cell 124 described above. The power source 1050 may include, or may be, a battery module 120. The power source may provide electrical energy to the aerosol generating device 100 that provides a voltage in the range of 3V to 18V, preferably in the range of 3V to 4.2V. In a preferred embodiment, the voltage source (which may be a battery cell 110) is a lithium-ion secondary battery supplying a value of 3.7V. Such a voltage source is particularly advantageous for modern aerosol generating devices in terms of rechargeability, high energy density, and large capacity. The power source 1050 provides power for the operation of the aerosol generating device 100, for example, it may provide the power necessary to generate an aerosol. In one example, the power source 1050 may power one or more heaters 1006.

[0251] As described above, the battery module 120 may comprise one or more battery module components, and the battery module 120 may comprise a visual indicator 150 configured to indicate the characteristics of the battery module components.

[0252] Furthermore, the aerosol generating device 100 in Figure 13 may include a battery module 120 comprising a plurality of spaces (not shown in Figure 13) defined by the components of the aerosol generating device 100, and one or more battery module components 122 arranged within the plurality of spaces 110a to c.

[0253] The aerosol generating device 100 may include a controller 1030. The controller 1030 is connected to a control unit 1008. The controller 1030 is configured to receive data from the control unit 1008. In particular, the controller 1030 is configured to receive data from the control unit 1008 regarding various sensors / inputs of the aerosol generating device 100 (such as a start input sensor 1018, a puff sensor 1020, and / or a temperature sensor 1022).

[0254] The controller 1030 and the control unit 1008 may be integrated with each other. In one example, a single component performs the functions of both the control unit 1008 and the controller 1030. In other examples, the control unit 1008 and the controller 1030 are separate components.

[0255] The aerosol generating device 100 may be equipped with a USB port 1052 (e.g., a USB receiving port). The USB port may provide a connection to the controller 1030.
