Description

Aerosol generation device, battery module, and method

The present disclosure relates to an aerosol generation device. The present disclosure further relates to a battery module. The present disclosure further relates to a method.

Background

An aerosol generation device is configured to heat an aerosol substrate to generate aerosol for inhalation. An aerosol generation device includes a power supply in the form of a battery cell. The battery cell provides power for operation of the aerosol generation device, and for example may provide the necessary power to generate aerosol. The battery cell may be incorporated in a battery module comprising the battery cell and/or other battery module components.

An aerosol generation device must typically comprise many components whilst maintaining a small form factor. An existing approach involves providing aerosol generation device components and a battery module in a layered construction. Available space within the aerosol generation device is not optimally used. It is desired to make improved use of available space within an aerosol generation device.

Battery module replacement and recycling is also an important consideration. It may be desired to access the battery module of the aerosol generation device to replace battery module components. It is desired to make removal and replacement of battery module components simpler and more intuitive. Ensuring authenticity of replacement battery module components is also an important consideration.

Furthermore, and related to battery module replacement and recycling, dangers associated with extraction of the battery module include electrical, chemical, and thermal dangers, and their potential interactions. It is desired to improve safety in accessing and replacing the battery module in an aerosol generation device.

It is the object of the invention to overcome at least some of the above referenced problems, or problems referenced elsewhere.

Summary According to the present disclosure there is provided an aerosol generation device, battery module, and method including the features as set out in the claims.

According to a first aspect of the present invention, there is provided an aerosol generation device comprising: a plurality of volumes defined by components of the aerosol generation device; and a battery module comprising one or more battery module components located within the plurality of volumes.

By this construction, improved use of available space within the aerosol generation device is made. Specifically, volumes defined by components (which may mean volumes provided between, or defined by interspaces between, components) are made use of to locate components of the battery module. Informally, the volumes may be seen as “gaps” between components, and said gaps at least partially “filled” by locating battery module components therein.

Furthermore, removal of battery module components is simpler as the battery module components can be removed from said volumes in one process or movement. Moreover, replacement is simpler and more intuitive as replacement battery module components can be installed in said volumes in one process or movement. This is in contrast to existing approaches where battery module components are inserted wherever possible within the aerosol generation device, and not into volumes defined by components which may be suitable (or specifically designed or arranged) to receive components. In the present example, the volumes may be suitable for receiving (e.g., specifically designed or arranged) to receive one or more battery module components.

By such a construction, it is also possible to ensure authentic replacement parts are used, as there is a requirement for “matching” or “keying” of the form factor of the replacement battery module components with the volumes defined by the components. For example, if a battery module is used which is not of an appropriate configuration, its components will not fit into the volumes of the aerosol generation device.

In one example, the components defining the plurality of volumes include one or more casing portions and one or more printed circuit boards, PCBs.

Such a construction facilitates use of space within the aerosol generation device that may otherwise be wasted or not utilised in assembling the aerosol generation device. Furthermore, the PCB and/or one or more casing portions can advantageous be adapted or shaped to define the volumes thereby to receive the one or more battery module components.

In one example, one or more of the one or more PCBs provides a wall of a compartment providing or defining the volumes.

That is, the volume may be the internal space in which the components are to be provided, with compartments providing the internal space and having outer bounds or surfaces defined by components of the aerosol generation device. Compartments may be shaped to receive the one or more battery module components. Specifically, here, the one or more PCBs provide the compartment walls. Notably, conventional aerosol generation devices are not constructed to use PCBs to provide walls of compartments within the aerosol generation device.

In this way, utilisation of available space in the device is achieved. Furthermore, a secure connection of battery module components can be made. Additionally, it has been realised that using PCBs to provide a compartment wall is highly advantageous in maximising use of available space, and facilitating a space-saving approach where an electrical connection is to be made with said PCBs.

In one example, the battery module is configured to provide electrical power to the aerosol generation device via a releasable electrical connection formed with the one or more PCBs that provide the wall of the compartment.

Such an arrangement may require more space, or internal volume, than a soldered connection typically found where the battery module is not removable. However, in the present construction, improved use of the available space within the aerosol generation device is made by utilising the volumes. Furthermore, access to said connections is simplified by utilising the volumes. This facilitates removal of the battery module whilst reducing the amount of dismantling of the aerosol generation device required to access and remove the battery module.

In one example, the one or more battery module components are removably located within the plurality of volumes. In this way, the one or more battery module components can be removed so as to be replaced with new battery module components, and/or the removed battery module components recycled.

In one example, the plurality of volumes are defined by a printed circuit board (PCB) and/or one or more casing portions of the aerosol generation device.

In one example, the one or more battery module components correspond to one of the volumes, optionally a specific volume, optionally wherein the one or more battery module components are shaped or sized to correspond to one of the volumes.

In this way, an optimum match or fit of the battery module components to the volumes is provided. This may also prevent incorrect installation of battery module components into the volumes, and improve simplicity of the installation, by requiring certain components to be installed in certain volumes (as a form of “poka-yoke” mechanism).

In one example, the volumes are provided or defined by a plurality of compartments.

That is, the volume may be the internal space in which the components are to be provided, with compartments providing the internal space and having outer bounds or surfaces defined by components of the aerosol generation device. Compartments may be shaped to receive the one or more battery module components.

In this way, utilisation of available space in the device is achieved. Furthermore, a secure connection of battery module components can be made.

In one example, the battery module comprises a first part of a sensor arrangement, and a second part of the sensor arrangement is provided at the at least one of the plurality of volumes. In this way, correct (i.e. , proper) location of the one or more battery module components within the plurality of volumes can be determined and ensured (i.e. sensed). Such a construction may facilitate prevention of operation of the battery module, or of the aerosol generation device, until the battery module components are correctly located within the volumes. This may improve safety. Furthermore, such a construction can allow non-authentic replacement parts to be identified.

In one example, the second part of the sensor arrangement is configured to sense the first part of the sensor arrangement.

In this way, correct (i.e., proper) location of the one or more battery module components within the plurality of volumes can be determined and ensured.

In one example, the sensor arrangement comprises a proximity sensor.

In this way, a signal can be provided by the sensor to indicate that the battery module components are correctly oriented.

In one example, the second part of the sensor arrangement is provided on a battery module component that is separate to a battery cell.

This may simplify installation by reducing problems relating to uncertainty in correctly locating battery module components other than the battery cell. Whilst in some examples it may be readily determinable where the battery cell need be installed, the correct location for other battery module components may not be readily determinable. Such a construction thus ensures correct placement of battery module components other than the battery cell.

In one example, the sensor arrangement provides or generates an output signal to authenticate the battery module and/or ensure proper connection.

In this way, an authentic battery module (or authentic components thereof) can be established. Furthermore, a proper connection of the battery module (e.g., correct placement, and/or correct electrical connection) can be established, which improves safety. In one example, the one or more battery module components comprise: a battery cell; and one or more additional battery module components.

By such a construction, improved use of the internal space available in the aerosol generation device is made, by locating the relatively bulky battery cell in a volume defined by components of the aerosol generation device. This may be in contrast to existing approaches which do not make use of space which may remain around, or adjacent to, the battery cell. For example, existing approaches may incorporate a layered construction of a battery cell with other components of the aerosol generation device, rather than locating the battery cell within one or more volumes defined by components of the device.

The battery cell may be shaped to be located in a plurality of volumes. That is, a single battery cell may be shaped to be located in a plurality of volumes. The battery cell may comprise a plurality of sub-cells. The battery cell may comprise protruding regions to be located in said volumes. A part or portion of the battery cell may extend outside of the volumes, and said portion may extend between protrusions of the battery cell such that the single battery cell is locatable in a plurality of volumes.

In one example, the one or more additional battery module components comprises a battery module hardware protection system and/or an interface.

In this way, an improved arrangement of battery module components is provided, wherein additional battery module components can be located within said volumes. The battery module hardware protection system may comprise, or be, a fuse and/or a protection IC module. The interface may comprise a screen or display. Additionally, or alternatively, the interface may comprise a visual indicator arranged to indicate a battery module component characteristic.

In one example, the battery module comprises a plurality of battery module components connected to one another by one or more connection elements. The connection elements may be locatable outside of the volumes.

In this way, battery module components are connectable. Furthermore, battery module components located within volumes can be connected whilst making use of available space within the aerosol generation device. The connection elements may comprise, or be, one or more flexible connections. The flexible connections may be thin-film connections, and may be electrical connections. The flexible connections may comprise layers of electrical conductors and insulation provided in a parallel arrangement. The flexible nature of the connections allows for any required relative movement or manipulation of the components when inserting/remove the battery module. The flexible functionality might also increase space-saving, since a definite, reserved space for a rigid connector is not necessarily required.

According to a second aspect of the present invention, there is provided a battery module for an aerosol generation device, the aerosol generation device comprising a plurality of volumes defined by components of the aerosol generation device, wherein the battery module comprises one or more battery module components locatable within the plurality of volumes.

In this way, an advantageous battery module is provided for an aerosol generation device, with associated benefits in improving use of available space within an aerosol generation device, simplifying removal and replacement of the battery module, ensuring authenticity of the battery module, and improving safety.

The second aspect of the present invention may incorporate any or all features of the first aspect of the present invention, as desired or as appropriate.

Whilst such an arrangement may require more space, or internal volume, than a soldered connection typically found where the battery module is not removable, by utilising the volumes, improved use of the available space within the aerosol generation device is made. Furthermore, access to said connections is simplified by utilising the volumes. This facilitates removal of the battery module whilst reducing the amount of dismantling of the aerosol generation device required to access and remove the battery module.

According to a third aspect of the present invention, there is provided a method of assembling an aerosol generation device, comprising: providing a battery module comprising one or more battery module components; and locating the one or more battery module components within a plurality of volumes defined by components of the aerosol generation device.

In this way, an advantageous method is provided for assembling aerosol generation device, with associated benefits in improving use of available space within an aerosol generation device, simplifying removal and replacement of the battery module, ensuring authenticity of the battery module, and improving safety. The third aspect of the present invention may incorporate any or all features of the first and/or second aspect of the present invention, as desired or as appropriate.

In one example, the components defining the plurality of volumes include one or more casing portions and one or more printed circuit boards, PCBs. The method may comprise arranging one or more casing portions and one or more PCBs to define a plurality of volumes.

In one example, one or more of the one or more PCBs provides a wall of a compartment providing or defining the volumes. The method may comprise providing a wall of a compartment providing or defining the volumes using one or more of the one or more PCBs, or by so arranging one or more of the one or more PCBs.

In one example, the battery module is configured to provide electrical power to the aerosol generation device via a releasable electrical connection formed with the one or more PCBs that provide the wall of the compartment. The method may comprise configuring the battery module to provide electrical power to the aerosol generation device by forming an electrical connection with the one or more PCBs that provide the wall of the compartment.

According to a fourth aspect of the present invention, there is provided a battery module for an aerosol generation device, comprising one or more battery module components, wherein the battery module comprises a visual indicator arranged to indicate a battery module component characteristic.

By such a construction, an operator is able to determine a characteristic of a battery module component by reference to the battery module. This is in contrast to existing examples of aerosol generation devices in which characteristics of battery module components may be indicated to an operator by the aerosol generation device, but are not indicated by the battery module itself. The present construction is highly advantageous in improving safety during disassembly of the aerosol generation device, and replacement or recycling of battery module components, as the operator need only refer to the battery module rather than to other systems which may be provided at the aerosol generation device.

The visual indicator may be distinct from, different to, or separate from, a user interface of the aerosol generation device. Conventional aerosol generation devices may comprise user interfaces indicating, for example, a battery cell charge level. However, the present visual indicator is comprised in (e.g., specific to) the battery module, rather than receiving a signal from another system or component of the aerosol generation device, such as a processor or controller of the aerosol generation device. The visual indicator may provide a visual indicator without the use of electronic means. The visual indicator may be a chemical indicator of an electrical characteristic of the battery module component. The visual indicator may be operable to indicate a battery module component characteristic when the battery module is disconnected from the aerosol generation device (i.e., when the battery module is provided in isolation).

In one example, the battery module comprises: one or more connection elements connecting to the one or more battery module components, wherein the one or more connection elements comprises the visual indicator.

In this way, connection elements provided in the battery module can be used as a means to indicate battery module component characteristics to an operator. This improves safety of removal and replacement of battery module components.

The one or more connection elements may be thin-film connections. The one or more connection elements may be flexible connections. This may enable the connection elements to be located in a suitable location for viewing by an operator. The one or more connection elements may be electrical connection elements, and the electrical connection elements may provide a visual indication of an electrical characteristic of the battery module component.

In one example, the battery module component characteristic is related to operation of the one or more battery module components.

In this way, an operator can determine whether the battery module component is operating correctly, or will continue to operate correctly.

The battery module component may be a battery cell, and the battery module component characteristic may be a charge level of the battery cell. Additionally, or alternatively, the battery module component characteristic may be a reference, or identification information, of the battery module component or of the battery module as a whole. The battery module component may be a battery cell, and the battery module component characteristic may be an expiry date of the battery cell or an indication of a level of degradation of the battery cell. In this way, an operator may establish that the battery cell requires replacement by reference to the visual indicator of the battery module, rather than by reference to a user interface of the aerosol generation device. In one example, the battery module component characteristic is related to an electrical state of the one or more battery module components.

The electrical state may be a current charge level, or voltage, of the battery cell. In this way, an operator may establish that the battery cell is discharged and is safe to remove and handle, thus minimising risk to the operator of thermal runaway during handling.

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

In this way, the battery module may indicate characteristics of the battery cell and/or of the battery module hardware protection system. The battery module hardware protection system may comprise, or be, a fuse and/or a protection IC module. This improves safety in replacement of said components.

In one example, the battery cell characteristic indicator provides an indication of charge level of the battery cell, degradation level of the battery cell, and/or expiry date of the battery cell.

In this way, information can be indicated to the user to inform a decision on removal and replacement of a battery cell of the aerosol generation device.

In one example, the visual indicator comprises a chemical indicator of battery cell charge level.

In this way, the charge level may be indicated to the operator without use of an electronic display, which may thereby provide a more reliable output to the operator. Furthermore, construction may be simplified by avoiding need for additional electronic components. The visual indicator may comprise a chemical indicator of battery cell voltage.

In one example, the visual indicator is operable to provide the indication of the battery module component characteristic. The visual indicator may be operable by an operator to provide the indication. In this way, the indication of the battery module component characteristic may be provided only when desired by the operator. This improves the lifetime of the battery module component, as the indication of the characteristic is not provided when not needed. This is particularly advantageous when the battery module component is a battery cell, whereby the indication of the battery cell characteristic (e.g., charge level) is providable only when the visual indicator is operated by the operator.

The visual indicator may be operable to form, or complete, an electrical circuit. The visual indicator may be a thermochromic indicator. The visual indicator may be operable by the application of pressure on one or more contacts to form, or complete, an electrical circuit.

In one example, the battery module is provided behind a cover assembly comprising a viewing assembly for viewing the visual indicator.

In this way, the operator may be protected from contacting the battery module or components thereof in an assembled arrangement, but battery module component characteristics can still be monitored by viewing the visual indicator via the viewing assembly. In this way, the characteristic of the battery module component can be determined and monitored prior to disassembly. Safety of the disassembly process is thus improved.

According to a fifth aspect of the present invention, there is provided an aerosol generation device comprising a battery module according to the fourth aspect of the present invention.

In this way, in an aerosol generation device, an operator is able to determine a characteristic of a battery module component by reference to the battery module. This is in contrast to existing examples of aerosol generation devices in which characteristics of battery module components may be indicated to an operator by the aerosol generation device (or systems or modules other than the battery module), but are not indicated by the battery module itself. The present construction is highly advantageous in improving safety during disassembly of the aerosol generation device, and replacement or recycling of battery module components, as the operator need only refer to the battery module rather than to other systems which may be provided at the aerosol generation device. The fifth aspect of the present invention may comprise any or all features of any of the aspects introduced above, as desired or as appropriate.

According to a sixth aspect of the present invention, there is provided a battery module for an aerosol generation device, comprising: a plurality of battery module components; wherein the battery module components are connected by one or more flexible connections.

By such a construction, connections can be formed between battery module components provided in different volumes, or in dispersed locations.

In one example, the one or more flexible connections are thin-film connections.

Optimal use of available space in the aerosol generation device is thus made.

In one example, the one or more flexible connections are electrical connections.

An electrical connection can thus be more easily formed between battery module components provided in different volumes, or in dispersed locations.

In one example, the battery cell comprises a plurality of battery sub-cells.

The incorporation of unique battery cell constructions is thus facilitated.

According to a seventh aspect of the present invention, there is provided an aerosol generation device comprising a battery module according to the sixth aspect of the present invention.

The seventh aspect of the present invention may comprise any or all features of any of the aspects introduced above, as desired or as appropriate.

According to an eighth aspect of the present invention, there is provided a method of installing a battery module in an aerosol generating device comprising: manipulating one or more flexible connections connecting battery module components to locate the battery module in the aerosol generating device. The eighth aspect of the present invention may comprise any or all features of any of the aspects introduced above, as desired or as appropriate.

Detailed Description

As used herein, the term “aerosol precursor material”, “vapour precursor material” or “vaporizable material” are used synonymously and may refer to a material and/or composition, which may for example comprise nicotine or tobacco and a vaporising agent. The aerosol precursor material is configured to release an aerosol when heated or otherwise mechanically stimulated (such as by vibrations). Tobacco may take the form of various materials such as shredded tobacco, granulated tobacco, tobacco leaf and/or reconstituted tobacco. Nicotine may be in the form of nicotine salts. Suitable vaporising agents include: a polyol such as sorbitol, glycerol, and glycols like propylene glycol or triethylene glycol; a non-polyol such as monohydric alcohols, acids such as lactic acid, glycerol derivatives, esters such as triacetin, triethylene glycol diacetate, triethyl citrate, glycerin or vegetable glycerin. In some examples, the aerosol precursor material is substantially a liquid that holds or comprises one or more solid particles, such as tobacco. An aerosol generation device is configured to aerosolise an aerosol precursor material without combustion in order to facilitate delivery of an aerosol to a user. Furthermore, and as is common in the technical field, the terms “vapour” and “aerosol”, and related terms such as “vaporize”, “volatilize” and “aerosolise”, may generally be used interchangeably.

As used herein, the term “aerosol generation device” is synonymous with “aerosol generating device” or “device” 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 refer to the device being for use when held by a user. The device may be adapted to generate a variable amount of aerosol, which can be controlled by a user input.

As used herein, the term “aerosol” may include a suspension of vaporizable material as one or more of: solid particles; liquid droplets; gas. Said suspension may be in a gas including air. Aerosol herein may generally refer to/include a vapour. Aerosol may include one or more components of the vaporizable material.

Referring to Figure 1 , an aerosol generation device 100 is shown in an exploded, side cross-sectional view. The aerosol generation device 100 is shown in schematic, with only details necessary for understanding the relevant concepts described herein being illustrated in Figure 1. That is, a number of components used in the generation of aerosol may also be comprised in the aerosol generation device 100, but are not illustrated in Figure 1 for simplicity. A more detailed example of an aerosol generation device is illustrated in Figure 9. The skilled person will appreciate that this detail may be incorporated in the aerosol generation device 100.

The aerosol generation device 100 comprises a plurality of volumes 110a - c. The volumes 110a - c are defined by components 102 of the aerosol generation device 100.

The aerosol generation device 100 comprises a battery module 120. The battery module 120 comprises one or more battery module components 122. The one or more battery module components 122 are locatable within the plurality of volumes 110a - c.

Referring to Figure 2, the aerosol generation device is shown in an assembled view. The one or more battery module components 122 are located within the plurality of volumes 110a - c. By this construction, improved use of available space within the aerosol generation device 100 is made. Specifically, the volumes 110a - c defined by components 102 (which may mean volumes 110a - c provided between, or defined by interspaces between, components 102) are made use of to locate the one or more battery module components 122. Informally, the volumes may be seen as “gaps” between components 102, and said gaps “filled” by locating battery module components 122 therein.

Furthermore, removal of battery module components 122 is simplified as the battery module components 122 can be removed from said volumes 110a - c. Moreover, replacement is simpler and more intuitive as replacement battery module components can be installed in said volumes 110a - c. This is in contrast to existing approaches where battery module components are inserted in a unique, perhaps separate, location within the aerosol generation device 100, and not into volumes defined by components which may be suitable (or specifically designed or arranged) to receive components. In the present example, the volumes 110a - c may be suitable for receiving (e.g., specifically designed or arranged) to receive one or more battery module components 122.

By such a construction, it is also possible to ensure authentic replacement parts are used, as there is a requirement for “matching” of the form factor of the replacement battery module components with the volumes 110a - c defined by the components 102.

The aerosol generation device 100 comprises an outer case 104 and an outer case cover 106. The outer case cover 106 is connectable to the outer case 104 to house components (including the battery module 120) therein.

As above, the components 102 of the aerosol generation device 100 define the plurality of volumes 110a - c. The components 102 may be known as aerosol generation device components, or system components. The components 102 may be those other than battery module components 122.

The components 102 are arranged or installed in the aerosol generation device 100 in a suitable manner. The components 102 may be arranged so as to define volumes 110a - c (otherwise referred to as “gaps”). The volumes 110a - c may be provided deliberately, for locating or receiving the one or more battery module components therein. Alternatively, the volumes 110a - c may be incidentally provided, as a result of the arrangement of the components 102 within the aerosol generation device 100. Whilst existing aerosol generation devices may comprise volumes defined by components of the aerosol generation device, existing approaches do not make appropriate or any use of such volumes. Instead, many existing approaches incorporate battery modules in a unique volume specifically designed for the battery module, which may be a parallelepiped and unique volume. An important feature of the present invention is that such volumes can be used to locate one or more battery module components 122 therein. The available space in the aerosol generation device 100 can thus be used more effectively. It is also an important feature that the one or more battery module components 122 are located within a plurality of volumes 110a - c, rather than in a single volume as in conventional arrangements. It is thus possible to make use of available space provided by multiple volumes within the aerosol generation device 100.

Furthermore, the battery module 120 may be removably located in the aerosol generation device 100. That is, the battery module 120 may be a removable battery module 120 (or “removably locatable battery module 120” or “a battery module 120 removably located or provided in the aerosol generation device 100”).

It is highly advantageous to provide a removable battery module 120 comprising battery module components 122 located within the volumes 110a - c. Firstly, the removable battery module 120 may comprise one or more connections for forming a releasable electrical and/or engaging connection with a component of the aerosol generation device 100 (such as components 102), which may involve forming a connection with a PCB 108 of the aerosol generation device 100. The connection may be made by connecting a first connecting part 115a of the battery module 120 with a second connecting part 115b of the PCB 108. The connection may be releasable. This requires more space than a soldered connection typically found where the battery module is not removable. By utilising the volumes 110a - c, improved use of the available space within the aerosol generation device 100 is made. Furthermore, access to said connections is simplified by utilising the volumes 110a - c. This facilitates removal of the battery module 120 whilst reducing the amount of dismantling of the aerosol generation device 100 required to access and remove the battery module 120. The first connecting part 115a of the battery module 120 may be electrically connected with a connection element 140 of the battery module 120. The first connecting part 115a and second connecting part 115b may together be referred to as a releasable electrical connection 115, or a releasable electrical connection arrangement 115. The battery module 120 may be connected to the aerosol generation device 100. The battery module 120 may be connected to at least one of the components 102 of the aerosol generation device 100. An electrical connection may be formed between the battery module 120 and the at least one of the components 102 of the aerosol generation device 100 when the battery module 120 is located in the volumes 110a - c. For example, the electrical connection may be formed by the releasable electrical connection 115 described above.

The electrical connection may be formed at a single point or location. That is, the battery module 120 may comprise an electrical connector, and the aerosol generation device may comprise a corresponding electrical connector for connecting to the electrical connector of the battery module 120. One of the battery module components 122 may comprise, or be provided with, the electrical connector, and other battery module components may be absent an electrical connector. Said other battery module components may comprise connectors for forming a mechanical connection with the volumes 110a - c, or components 102 of the aerosol generation device 100, but only a single electrical connection need be provided. Power may be provided from the battery module 120 to the aerosol generation device 100 via the electrical connection. The battery module 120 may be electrically connected to the aerosol generation device 100 at a PCB of the aerosol generation device 100.

In an example, an insulating body (not shown) is provided in a region, or space, between at least a part of the battery module 120 and at least one of the volumes 110a - c. The insulating body may be provided on or around one or more battery module components 122. This provides protection to the components 102 of the aerosol generation device 100 from the battery module 120, for example preventing electrical short circuits and/or overheating of components 102 of the aerosol generation device 100 due to operation of the battery cell 124.

In an example, the one or more battery module components 122 comprise a battery cell 124 and one or more additional battery module components. The one or more additional battery module components comprises 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. The one or more additional battery module components may comprise an interface (e.g., a user interface). In an example, the one or more battery module components 122 are removably located within the plurality of volumes 110a - c.

Related advantages of such a construction will be apparent from the above. Furthermore, in this way, individual components can be removed from the volumes 110a - c, and from the aerosol generation device 100, for replacement and/or recycling.

In an example, the plurality of volumes 110a - c are defined by a printed circuit board 108 (PCB) and/or one or more casing portions of the aerosol generation device 100. The one or more casing portions may be portions of the outer case 104 and/or portions of the outer case cover 106. The casing may otherwise be referred to as a housing.

In a highly advantageous example relating to the above, the plurality of volumes 110a - c are defined by one or more casing portions 104, 106 and one or more PCBs 108. One or more of the one or more PCBs 108 provide a wall of a compartment 111a - c providing or defining the volumes 110a - c. The battery module 120 is configured to provide electrical power to the aerosol generation device 100 via a releasable electrical connection 115.

In an example, the one or more battery module components 122 correspond to one of the volumes 110a - c. The volumes 110a - c may be, or comprise, a specific volume. The one or more battery module components 122 may be shaped or sized to correspond to one of the volumes 110a - c.

In other words, each battery module component 122 may correspond to a specific volume 110a - c. Each battery module component 122 may be an insertable component, and the volumes 110a - c may be receiving volumes, configured to receive the insertable component.

In this way, the volumes 110a - c provide a unique 3D pattern. This simplifies the replacement of the battery module 120, as only a battery module having a suitable configuration are insertable and receivable in the volumes 110a - c. This can be used to ensure only authentic and/or suitable battery modules are used in the replacement process. In an example, the volumes 110a - c are provided or defined by a plurality of compartments.

Each compartment may be defined by surfaces of the components of the aerosol generation device 100 and comprise a volume of the volumes 110a - c.

The battery module 120 may be attachable or connectable to a surface of the compartment, for example to a compartment wall. That is, the battery module 120, or a battery module component 122, may be attachable to a part of a component 102 of the aerosol generation device 100. An attachment mechanism may be provided, with a first part of the attachment mechanism provided at the battery module 120 and a second part of the attachment mechanism provided at the compartment.

In an example, the aerosol generation device 100 comprises a sensor arrangement 132. The battery module 120 comprises a first part 132a of the sensor arrangement 132, and a second part 132b of the sensor arrangement 132 is provided at at least one of the plurality of volumes 110a - c. The second part 132b of the sensor arrangement 132 may be provided in, or at a surface of, a compartment.

In the example illustrated in Figures 1 and 2, the first part 132a of the sensor arrangement 132 is provided on battery cell 124. However, it will be appreciated that the first part 132a of the sensor arrangement 132 may be provided elsewhere on or in the battery module 120, and the second part 132b of the sensor arrangement 132 provided at a corresponding volume 110a - c so that the parts may cooperate to perform sensing.

In an example, the second part 132b of the sensor arrangement 132 is configured to sense the first part 132a of the sensor arrangement 132.

In this way, proper insertion, engagement and connection of the battery module in the volumes 110a - c can be ensured.

In an example, the sensor arrangement 132 comprises a proximity sensor. The proximity sensor may be a hall effect sensor. In an example, the second part 132b of the sensor arrangement 132 is provided on a battery module component 122 that is separate to the battery cell 124. That is, the second part 132b of the second arrangement 132 is provided on a battery module component 122 that is not the battery cell 124.

In this way, it may be simpler and cheaper to replace only the battery cell 124 of the battery module 120.

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

In an example, the sensor arrangement may comprise a plurality of sensors locatable on or in different battery module components 122 and volumes 110a - c. That is, each battery module component 122 may comprise a first part of a sensor and each volume 110a - c may comprise a corresponding second part of the sensor. In this way, an output signal may be provided as a combination of signals from the plurality of sensors, ensuring proper connection of each battery module component 122 in each volume 110a - c.

In an example, the battery module 120 comprises a plurality of battery module components 122 connected to one another (i.e., connected together) by one or more connection elements 140. The connection elements 140 may be locatable outside of the volumes 110a - c.

That is, in an example, the one or more connection elements 140 connect battery module components 122 located in different volumes 110a - c. The one or more connection elements 140 may extend between the components partially, or completely, outside of the volumes 110a - c.

In this way, connection of separated battery module components 122 (e.g., those provided in different volumes 110a - c) can be achieved. This improves utilisation of space in the aerosol generation device 100, rather than requiring a single volume in which all components and connections must be provided. The one or more connection elements 140 may comprise, or be, one or more flexible connections. The flexible connections may be thin-film connections, and may be electrical connections. The flexible connections may comprise layers of electrical conductors and insulation provided in a parallel arrangement.

Referring to Figure 3, exemplary arrangements of connection elements 140 are shown.

Referring to Figure 3(a), a portion of a battery module 120 is shown. Connection elements 140 connect a plurality of battery module components 122. In the illustrated example, the components 122 are components of the battery module hardware protection system 126 comprising a fuse 126a and a protection IC module 126b.

The connection element 140 comprises a layered, stacked, or superposed, construction of polyimide films 142 and metal (e.g., steel or copper) conductive layers 144. Polyimide films 142 may be used in forming flexible printed circuits. The connection elements 140 are flexible, allowing the connection elements 140 to be bent or manipulated in tight angles. This facilitates connection of battery module components 122 provided in volumes 110a - c. Furthermore, this simplifies connection of components in an aerosol generation device having a curved or rounded outer profile. Thin film connections also do not require much space in the aerosol generation device, thus enabling a reduction in device form factor and/or freeing up space for additional componentry.

Referring to Figure 3(b), an exemplary arrangement of connection elements 140a, 140b is shown. The connection elements 140a, 140b connect either side of a battery module component, specifically a PCB 146. Such a construction allows a narrow connection, e.g., an electrical connection formed in a narrow or limited space. The connection elements 140a, 140b connect to the PCB 146 using flat tabs. Flat tabs allow conduction of high electrical current, and simplifies connection to the PCB.

Referring to Figure 3(c) and 3(d), a further exemplary arrangement of connection elements 140c, 140d is shown. The connection elements 140c, 140d are connected to a single side of a battery module component, specifically a PCB 148. The connection elements 140c, 140d connect to the PCB 146 using flat tabs. Flat tabs allow conduction of high electrical current, and simplifies connection to the PCB. Referring to Figure 4, a battery module 120 for an aerosol generation device 100 is schematically shown. The aerosol generation device 100 comprises a plurality of volumes 110a - c defined by components of the aerosol generation device 100. The battery module 120 comprises one or more battery module components 122 locatable within the plurality of volumes 110a - c.

It will be apparent that there are numerous advantages of providing only the battery module 120. The battery module 120 may be used to retrofit the aerosol generation device 100. Improved use of available space within the aerosol generation device 100 can be made. Furthermore, the battery module 120 may be readily replaced in the aerosol generation device 100, without intensive disassembly of the aerosol generation device.

Referring to Figure 5, a method of assembling an aerosol generation device is shown. Step S510 comprises providing a battery module comprising one or more battery module components. Step S520 comprises locating the one or more battery module components within a plurality of volumes defined by components of the aerosol generation device.

Referring to Figure 6, a battery module for an aerosol generation device is shown.

In this example, the battery module of Figure 6 is the battery module 120 as described above, and is for the aerosol generation device 100 as described above. That is, the battery module 120 as shown in Figure 6 may incorporate any or all of the features of the battery module 120 as described above, as desired or as appropriate. Nevertheless, it will be appreciated by the person skilled in the art that in other examples the battery module 120 as shown in Figure 6 may be a different battery module to that described above in relation to Figures 1 to 5, and need not require (i.e. , may be absent) features thereof.

The battery module 120 comprises one or more battery module components 122. The battery module 120 comprises a visual indicator 150. The visual indicator 150 is arranged to indicate a battery module component characteristic. A battery module component characteristic may be a characteristic of the one or more battery module components 122 (e.g., of one of the components 122 or of a combination of two or more battery module components 122, and may be of the battery module 120 as a whole). As introduced above, the visual indicator 150 is a part of the battery module 120. This is in contrast to examples of conventional aerosol generation devices which may incorporate visual indicators at the aerosol generation device, but are not comprised in a battery module thereof. This is a subtle but important distinction. In an example, in a conventional aerosol generation device, an indication of a battery cell charge level may be provided to a user of the aerosol generation device using a user interface of the aerosol generation device. The user interface may be connected to a controller or processor which does not form part of the battery module. However, in the present invention, it has been realised that in replacing the battery module 120 it is highly advantageous to incorporate a visual indicator of a battery module component characteristic in the battery module 120 itself.

When comprised in the aerosol generation device, the visual indicator 150 may be provided in addition to a user interface (e.g., a standard user interface) arranged to indicate a battery module component characteristic. The user interface may receive a signal from a processor of the aerosol generation device, the processor being connected to the battery module 120.

That is, the present visual indicator 150 is specific to the battery module 120. Conventional devices may incorporate visual indictors in the form of a battery charge level display, but it will be understood that such prior art indicators are not comprised in (or do not form part of) a battery module. The visual indicator 150 may be operable to indicate a battery module component characteristic when the battery module 120 is disconnected from the aerosol generation device 100 (i.e., when the battery module 120 is provided in isolation).

In an example, the battery module 120 comprises one or more connection elements 140. The one or more connection elements 140 connect, or are connectable to, the one or more battery module components 122. The one or more connection elements 140 comprise the visual indicator 150.

The connection elements 140 may provide electrical connections within the battery module 120. In this way, the one or more connection elements 140 provide dualfunctionality, in that they serve as both electrical connections and as a visual indicator of the battery module component characteristic. Advantageously, the visual indicator 150 being comprised in the connection element 140 enables the characteristic to be determined whilst also improving utilisation of available space in the battery module 120 and aerosol generation device 100. The connection element may be a thin film connection as described above.

In an example, the battery module component characteristic is related to operation of the one or more battery module components 122.

Operation may include the provision of electrical power from the battery module 120 to the aerosol generation device 100. Additionally, operation of the one or more battery module components 122 may be electrical operation of the one or more battery module components 122, and the characteristic may be representative of the electrical operation. In this way, an operator can determine whether the battery module component 122 is operating correctly, or will continue to operate correctly.

In an example, the battery module component characteristic is related to an electrical state of the one or more battery module components 122.

The electrical state may be a state of charge, or voltage, of the one or more battery module components 122.

The electrical state may be a current charge level, or voltage, of the battery cell 124. In this way, an operator may establish that the battery cell 124 is discharged and is safe to remove and handle, thus minimising risk to the operator of thermal runaway during handling.

In an example, the one or more battery module components 122 comprise a battery cell 124 and/or a battery module hardware protection system 126.

The battery module component characteristic may be a charge level of the battery cell 124. Additionally, or alternatively, the battery module component characteristic may be a reference, or identification information, of the battery module component 122, of the battery cell 124, or of the battery module 120 as a whole. The battery module component 122 may be a battery cell 124, and the battery module component characteristic may be an expiry date of the battery cell 124 or an indication of a level of degradation of the battery cell 124. In this way, an operator may establish that the battery cell requires replacement by reference to the visual indicator 150 of the battery module 120, rather than by reference to a user interface of the aerosol generation device 100.

Furthermore, in this way, the battery module 120 may indicate characteristics (via the visual indicator 150) of the battery cell 124 and/or of the battery module hardware protection system 126. The battery module hardware protection system 126 may comprise, or be, a fuse 126a and/or a protection IC module 126b. This improves safety in replacement of said components.

In an example, the visual indicator 150 provides an indication of charge level of the battery cell 124, degradation level of the battery cell 124, and/or expiry date of the battery cell 124.

Indicating the charge level of the battery cell 124 may allow an operator to establish that the battery cell 124 is discharged and is thus safe to handle during removal and replacement of the battery cell. Furthermore, indicating the degradation level of the battery cell 124 and/or the expiry date of the battery cell 124 may enable a determination that the battery cell 124 should be replaced. The degradation level may be an indication of a relative level of safety, reliability, or performance of the battery cell 120 (e.g., compared with a new battery cell 120).

In an example, the visual indicator 150 comprises a chemical indicator of battery cell charge level. The chemical indicator may be a thermochromic indicator of battery cell charge level. In this way, electronic means need not be required to indicate the battery cell module component characteristic. This may be well suited in a replacement process performed by an operator, which contrasts with conventional devices which comprise electronic means to indicate characteristics, such as battery charge level, to a user via a more intuitive electronic display.

In an example, the visual indicator 150 is operable to provide the indication of the battery cell module component characteristic.

The visual indicator may be operable by the application of pressure on one or more contacts to form, or complete, an electrical circuit. In this way, the visual indication may be provided only at a time when the operator desires to determine the battery cell module component characteristic. This may enhance the lifetime, or preserve charge of, the battery cell 124.

Referring to Figure 7, the battery module 120 is shown located in the aerosol generation device 100. In an example, the battery module 120 is provided behind a cover assembly 160 comprising a viewing assembly 162 for viewing the visual indicator 150.

In this way, the battery module 120, and specifically the battery cell 124, is shielded from the operator during the replacement process, whilst enabling the operator to determine whether the battery module 120 is safe to handle (due to being discharged) or whether the battery module 120 requires replacement (due to degradation level or having expired).

The viewing assembly 162 may comprise a slot in the cover assembly 160. The visual indicator 150 may be visible through the slot. The viewing assembly 162 may comprise a slot and a transparent or translucent material member provided in the slot through which the visual indicator 150 is visible. The slot may be known as an aperture.

Referring to Figure 8, an aerosol generation device 100 is shown. The aerosol generation device 100 comprises a battery module 120. The battery module 120 may be the battery module 120 as shown and described in relation to Figure 6 and 7. That is, the battery module 120 comprises one or more battery module components 122, and the battery module 120 comprises a visual indicator 150 arranged to indicate a battery module component characteristic.

Advantages of such a construction are numerous, and will be appreciated from the description provided herein.

In an example, the aerosol generation device 100 may comprise the cover assembly 160 comprising the viewing assembly 162 for viewing the visual indicator 150 of the battery module 120.

Figure 9 shows a schematic cross-sectional view of an aerosol generation device 100.

The aerosol generation device 100 may be any aerosol generation device 100 described above. That is, the aerosol generation device 100 described in relation to Figure 9 may incorporate any or all of the features described above, as desired or as appropriate.

The aerosol generation device 100 is suitable for receiving a consumable 1002 therein. For example, the aerosol generation device 100 may include a chamber 1004 in which the consumable 1002 is received.

The invention is not limited to the specific aerosol generation device 100 or consumable 1002 described herein. That is, the description of the aerosol generation device 100 and consumable 1002 is provided for illustrative purposes only. The skilled person will appreciate that alternative constructions of aerosol generation devices and consumables will be compatible with the present invention.

A consumable 1002 comprises an aerosol substrate. The term aerosol substrate is a label used to mean a medium that generates an aerosol or vapour when heated. Aerosol substrate might be interpreted as an aerosol precursor. In one example, aerosol substrate is synonymous with smokable material, aerosol generation substrate and aerosol generation medium. Aerosol substrate includes materials that provide volatilized components upon heating, typically in the form of vapor or an aerosol. Aerosol substrate may be a non-tobacco-containing material or a tobacco-containing material. Aerosol substrate may, for example, include one or more of tobacco per se, tobacco derivatives, expanded tobacco, reconstituted tobacco, tobacco extract, homogenized tobacco or tobacco substitutes. Aerosol substrate also may include other, non-tobacco, products, which, depending on the product, may or may not contain nicotine. Aerosol substrate may comprise one or more humectants, such as glycerol or propylene glycol.

The aerosol generation device 100 may comprise one or more heaters 1006 configured to provide heat to the consumable 1002, in use.

In one example, the consumable 1002 contains a liquid and the one or more heaters comprises a heating element, such as a coil, a ceramic heater, a flat resistive heater, a mesh heater, a MEMS heater, or the like, configured to aerosolise the liquid for inhalation. A liquid delivery element or mechanism, such as a porous material, a capillary system, and/or valve, may transfer the liquid to the heating element, in use. In some examples, the aerosolised liquid may pass through a solid substrate within the aerosol generation device 100. In other examples, the consumable 1002 may comprise a solid aerosol substrate.

In one example, the aerosol generation device 100 comprises a nebulizing engine, such as a vibrating mesh, to generate an aerosol from a liquid with or without heating thereof.

The aerosol generation device 100 may comprise a mouthpiece 1012 through which a user draws on the aerosol generation device 100 to inhale generated aerosol. The mouthpiece 1012 includes a vent or channel 1014 that is connected to a region close to the consumable 1002 for passage of any generated aerosol from the consumable 1002, during use. For example, the channel 1014 may extend between an opening in the mouthpiece 1012 and the chamber 1004 in which the consumable 1002 is at least partially receivable. The mouthpiece 1012 is arranged such it may be received in a user’s mouth in use. In other examples, a mouthpiece 1012 is not required and a portion of the consumable 1002 may protrude from the aerosol generation device 100. In this example, protruded portion of the consumable 1002 may work as mouthpiece.

The aerosol generation device 100 may comprise a control unit 1008 (or control circuitry) for electronic management of the device. The control unit 1008 may include a PCB or the like (not shown). The control unit 1008 is configured to control the one or more heaters 1006.

The aerosol generation device 100 may comprise an activation input sensor 1018. The activation input sensor 1018 may be a button, a touchpad, or the like for sensing a user’s input, such as a tap or swipe. In other examples, the activation input sensor 1018 comprises a consumable sensor configured to detect if a consumable 1002 has been inserted into the aerosol generation device 100. For example, the input sensor 1018 may comprise an authenticity detector that is configured to detect if an authentic consumable 1002 has been inserted into the aerosol generation device 100. Additionally, or alternatively, the user input may also comprise an inhalation action by a user.

The aerosol generation device 100 may comprise a puff sensor 1020 (otherwise known as an inhalation sensor). The puff sensor 1020 is configured to detect an inhalation action (or puff) by a user on the aerosol generation device 100. In one example, the puff sensor 1020 comprises a microphone or a flow sensor configured to an airflow within the chamber 1004 and/or an airflow channel extending from the chamber 1004 through the mouthpiece 1012 to an inhalation outlet thereof, the airflow being associated with a user’s inhalation action. In other examples, the puff sensor 1020 is configured to detect a change in pressure indicative of a beginning of an inhalation action on the aerosol generation device 100 by the user. In this case, the puff sensor 1020 may be located anywhere on the aerosol device 100 in which there would be a change in pressure due to an inhalation action of the user. In one example, the puff sensor 1020 is located in the channel 1014 between the chamber 1004 and the mouthpiece 1012 of the aerosol generation device 100. The puff sensor 1020 may also detect the end of an inhalation action by the user. For example, the puff sensor 1020 may be configured to detect a further change in pressure due to the end of an inhalation action of a user.

The aerosol generation 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 generation device 100. The one or more temperature sensors 1022 may comprise a temperature sensor, such as a thermocouple or thermistor, configured to be located within or adjacent to the consumable 1002 when it is received in the aerosol generation device 100. For example, the one or more temperature sensors 1022 may be located within the chamber 1004 of the aerosol generation device 100. In other examples, the temperature of the consumable 1002 may be indirectly measured by the use of thermal imaging sensors. In further other example, the heater 1006 itself works as a temperature sensor if the heater 1006 has PTC (Positive Temperature Coefficient) or NTC (Negative Temperature Coefficient) characteristic.

The aerosol generation device 100 may include a power supply 1050 such as a battery cell. The power supply 1050 may be the battery cell 124 described above. The power supply 1050 may comprise, or be, a battery module 120. The power supply may provide the aerosol generation device 100 with electrical energy providing a voltage in the range of 3 V and 18 V, preferably in the range of 3 V and 4.2 V. In a preferred embodiment the voltage source (which may be the battery cell 110) is a lithium-ion secondary battery delivering a value of 3.7 V. Such a voltage source is particularly advantageous for a modern aerosol generation device in view of rechargeability, high energy density and large capacity. The power supply 1050 may provide power for operation of the aerosol generation device 100, for example the necessary power to generate aerosol. In an example, the power supply 1050 may provide power to one or more heaters 1006. As above, the battery module 120 may comprise one or more battery module components, and the battery module 120 may comprise a visual indicator 150 arranged to indicate a battery module component characteristic.

Furthermore, the aerosol generation device 100 of Figure 9 may comprise a plurality of volumes (not shown in Figure 9) defined by components of the aerosol generation device 100; and a battery module 120 comprising one or more battery module components 122 located within the plurality of volumes 110a - c.

The aerosol generation device 100 may comprise a controller 1030. The controller 1030 is connected to the 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 relating to various sensors/inputs (such as the activation input sensor 1018, puff sensor 1020 and/or temperature sensor 1022) of the aerosol generation device 100.

The controller 1030 and the control unit 1008 may be integral with each other. In one example, a single component performs the function of the control unit 1008 and controller 1030. In other examples, the control unit 1008 and the controller 1030 are distinct components.

The aerosol generation device 100 may comprise a USB port 1052 (e.g., a USB receiving port). The USB port may provide connection to the controller 1030.

It will be appreciated that the invention that has been described and defined above may allow the related apparatus and methods to drive, comply with, or more easily comply with, legal and regulatory requirements, guidelines and standards. In particular, this might be in relation to one or more of apparatus (e.g. battery or related device) inspection, indication/status, recycling, reuse, repair, replacement, and maintenance, whether by an end user or service provider.

Referring generally to the description above, further detail is hereby provided in relation to terms used above and features described in the present disclosure, or to further terms relevant to the present disclosure: - A “battery” may mean any device delivering electrical energy generated by direct conversion of chemical energy, having internal or external storage, and consisting of one or more non-rechargeable or rechargeable battery cells or modules thereof, and includes a battery that has been subject to preparation for re-use, preparation for repurposing, repurposing or remanufacturing;
