Description

[Technical field]

[0001] The present invention relates to an aerosol generating device, and more particularly to battery verification in an aerosol generating device. [Background technology]

[0002] Aerosol generating devices, such as e-cigarettes and other aerosol inhalers or vaporizers, are becoming increasingly popular consumer products.

[0003] Heating devices for vaporization or aerosolization are known in the art. Such devices typically include a heating chamber and a heater. In operation, an operator inserts the product to be aerosolized or vaporized into the heating chamber. The product is then heated by an electronic heater to vaporize the product's ingredients for inhalation by the operator. In some examples, the product is a tobacco product similar to a traditional cigarette. Such devices are sometimes referred to as "heat-to-no-burn" devices because they heat the product to the point of aerosolization without burning it.

[0004] Aerosol generating devices are typically powered by a power system that includes a battery. When replacing such batteries, problems arise in ensuring the safety, reliability and quality of the battery in the new battery, as well as ensuring that a genuine or approved battery is used and that the new battery is not in fact an aged, damaged or otherwise unsuitable battery for the aerosol generating device. Summary of the Invention [Problem to be solved by the invention]

[0005] The object of the present invention is to address in particular the problems mentioned above. [Means for solving the problem]

[0006] In a first aspect, an aerosol generating device battery validation system is provided, the system comprising: a battery measurement module configured to perform a plurality of battery voltage measurements on a battery connected to the aerosol generating device; a battery validation module configured to determine whether a parameter of the battery meets a validation requirement based on a plurality of battery voltage measurements; a controller configured to set the aerosol generation device to an operable state when the parameter satisfies the validation requirement, and further configured to set the aerosol generation device to a restricted state when the parameter does not satisfy the validation requirement; Includes.

[0007] The characteristics of the battery based on the multiple voltage measurements may indicate whether the battery is an approved battery. By performing multiple battery voltage measurements of the battery, it is possible to determine whether the parameters of the battery meet the validation requirements based on these measurements. In this manner, the aerosol generating device may be controlled to be in an operable state when the parameters meet the validation requirements, and in a restricted state when the parameters do not meet the validation requirements. Thus, the use of the aerosol generating device is restricted for unapproved batteries or old, damaged or unsuitable batteries. This provides a robust, accurate and cost-effective method of determining whether a battery meets the requirements for use in an aerosol generating device, and can certify that the device is safe and reliable for use, thereby improving the reliability and quality of the operation of the aerosol generating device as well as the safety of the battery.

[0008] Preferably, the aerosol generation device battery verification system is configured to apply a first battery pulse and a second battery pulse at a predetermined time interval after the first battery pulse, and the battery measurement module is configured to measure a plurality of battery voltage measurements based on the first battery pulse and the second battery pulse.

[0009] In this manner, measurements of the battery may be determined and averaged for multiple loads applied to the battery, thereby improving the determination of whether the battery parameters meet validation requirements.

[0010] Preferably, the aerosol generating device battery validation system is configured to apply the first battery pulse and the second battery pulse as a discharge battery pulse in which power flows from the battery of the aerosol generating device to the heater; and / or The aerosol generating device battery validation system is configured to apply the first battery pulse and the second battery pulse as a charging battery pulse in which power flows from the second power source to the battery.

[0011] In this way, the validation process becomes more flexible.

[0012] Preferably, the aerosol generating device battery validation system is configured to apply the first battery pulse and the second battery pulse as a discharge battery pulse if the battery's state of charge is above a predetermined state of charge threshold.

[0013] Thus, if the battery has a fully charged state, the verification process can be performed using a discharge pulse, which is advantageous since the available discharge power is higher than the charge power. Using a discharge power allows for a more accurate internal resistance calculation due to the larger voltage drop, which means that inaccuracies in the voltage measurement have less impact on the internal resistance calculation. A discharge pulse also contributes to a larger pseudo open circuit voltage drop, which is also advantageous, and for the same reason, a higher current may increase the voltage change since it discharges the battery more in the same time than a lower current.

[0014] Preferably, the aerosol generating device battery validation system is configured to apply the first battery pulse and the second battery pulse as a charging battery pulse if the battery's state of charge is below a predetermined state of charge threshold.

[0015] In this way, when the battery does not have a sufficient state of charge, the verification process can be performed using a charge pulse, which avoids effects that may reduce the repeatability of the characteristics of a discharged battery when the battery has a low state of charge, and thus improves the accuracy of the verification process.

[0016] Preferably, the second power source comprises one or more supercapacitors within the aerosol generating device; or The second power source includes an external power source to which the aerosol generating device is connected.

[0017] Preferably, determining whether a parameter of the battery satisfies a validation requirement comprises: calculating an internal resistance of the battery based on the plurality of battery voltage measurements, and determining that the parameters of the battery meet the validation requirements when the calculated internal resistance is within a predetermined internal resistance range; calculating a voltage change of the battery based on the plurality of battery voltage measurements, and determining that the parameters of the battery meet the validation requirement when the voltage change of the battery falls within a predetermined voltage change range; Calculating an available capacity of the battery based on the plurality of battery voltage measurements, and determining that the parameters of the battery meet the validation requirements when the calculated available capacity of the battery is within a predetermined capacity range; and / or calculating an available capacity of the battery and an internal resistance of the battery based on the plurality of battery voltage measurements, and determining that the parameters of the battery meet the validation requirements when the calculated available capacity of the battery is within a predetermined capacity range for the calculated internal resistance of the battery. Includes at least one of the following.

[0018] In this manner, a determination can be made accurately as to whether or not a battery is a verified battery based on one or more parameters.

[0019] Preferably, the plurality of battery voltage measurements include battery voltage measurements taken before, during, between, during and after the first battery pulse; and The battery validation module is configured to calculate the internal resistance of the battery based on battery voltage measurements before, during, between, and during the first battery pulse.

[0020] In this way, measurements of the battery are taken at different times during two battery pulses when the battery is under different conditions, allowing an accurate determination of whether the parameters meet the validation requirements.

[0021] Preferably, the plurality of battery voltage measurements include a first open circuit battery voltage measured between the first and second battery pulses and a second open circuit battery voltage measured after the second battery pulse; and The battery validation module is configured to calculate an available capacity of the battery based on the first open circuit battery voltage and the second open circuit battery voltage.

[0022] Preferably, determining whether the parameter of the battery satisfies the validation requirement includes calculating an internal resistance of the battery based on a plurality of battery voltage measurements, and determining that the parameter of the battery satisfies the validation requirement when the calculated internal resistance is within a predetermined internal resistance range. Preferably, the plurality of battery voltage measurements include battery voltage measurements measured before, during, between the first and second battery pulses, and during the second battery pulse, and the battery validation module is configured to calculate the internal resistance of the battery based on the battery voltage measurements before, during, between, and during the second battery pulse. Preferably, the predetermined internal resistance range is based on a state of charge of the battery. Preferably, the predetermined internal resistance range is based on a state of charge of the battery and an ambient temperature in the vicinity of the aerosol generating device.

[0023] Preferably, determining whether the parameter of the battery satisfies the validation requirement comprises calculating a change in the voltage of the battery based on a plurality of battery voltage measurements, and determining that the parameter of the battery satisfies the validation requirement when the change in the voltage of the battery falls within a predetermined voltage change range. Preferably, the plurality of battery voltage measurements comprise a first open circuit battery voltage measured during a first battery pulse and a second open circuit battery voltage measured after a second battery pulse, and the change in voltage of the battery is determined as a difference between the first open circuit battery voltage and the second open circuit battery voltage.

[0024] Preferably, determining whether the parameter of the battery satisfies the validation requirement includes calculating an available capacity of the battery based on a plurality of battery voltage measurements, and determining that the parameter of the battery satisfies the validation requirement when the calculated available capacity of the battery is within a predetermined capacity range.

Preferably, the battery validation module is configured to calculate the available capacity of the battery based on a first open circuit battery voltage measured between the first and second battery pulses, a second open circuit battery voltage measured after the second battery pulse, and an integrated current during the second battery pulse, and calculate the internal resistance of the battery based on battery voltage measurements before, during, between, and during the first and second battery pulses, and the predetermined capacity range is based on a relationship between the internal resistance and a capacity range of the battery.

[0028] Low temperatures (i.e., below a certain temperature threshold) in the environment in which the device is installed (i.e., the ambient temperature outside the device) can adversely affect the battery chemistry, making the battery validation process less reliable. Inhibiting the validation process at such low temperatures avoids this, thereby making the validation process more reliable.

[0030] In this way, the validation requirements can be provided by an external device rather than being pre-stored by the validation system of the aerosol generating device, thus making better use of the computational resources of the aerosol generating device battery validation system and reducing the memory and storage resources required for the battery validation system.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0039] 1 shows a block diagram of the elements of an aerosol generating device 100, also known as an e-cigarette, or vapor generating device. For purposes of this specification, it will be understood that the terms "vapor" and "aerosol" are interchangeable.

[0040] The aerosol generating device 100 has a body portion 112 including the controller 102 and a power system including a battery 104. Although described herein as a single battery, the battery 104 may be one or more batteries or a battery pack. In some examples, the power system may include one or more supercapacitors as elements of a "dual power system" that includes both a battery and a supercapacitor.

[0041] The controller 102 is configured to control the operation of the aerosol generating device, which may include stopping and starting operation of the device based on the operating mode of the aerosol generating device, as well as controlling the power flow of the battery 104. The controller 102 may be at least one microcontroller unit that includes a memory that stores instructions for operating the aerosol generating device 100, and one or more processors configured to execute these instructions, including instructions for stopping and starting operation of the device, instructions for implementing the operating modes of the device, instructions for controlling the power flow from the battery, etc.

[0042] In one example, the heater 108 is included in the body portion 112. In such an example, as shown in FIG. 1 , the heater 108 is disposed within a cavity 110 or chamber of the body portion 112. The cavity 110 is accessed by an opening 110A in the body portion 112. The cavity 110 is positioned to house an associated aerosol-generating consumable 114. The aerosol-generating consumable may include an aerosol-generating material, such as a tobacco rod that includes tobacco leaves. The tobacco rod may be similar to a traditional cigarette. The cross section of the cavity 110 is approximately equal to the cross section of the aerosol generating consumable 114 and has a depth such that when the associated aerosol generating consumable 114 is inserted into the cavity 110, the first end 114A of the aerosol generating consumable 114 reaches the bottom 110B of the cavity 110 (i.e., the end 110B of the cavity 110 remote from the cavity opening 110A) and the second end 114B of the aerosol generating consumable 114 remote from the first end 114A extends outward from the cavity 110. In this manner, a consumer can inhale the aerosol generating consumable 114 when the aerosol generating consumable 114 is inserted into the aerosol generating device 100. In the example of FIG. 1, the heater 108 is positioned in the cavity 110 such that the heater 108 engages the aerosol generating consumable 114 when the aerosol generating consumable 114 is inserted into the cavity 110. 1, the heater 108 is disposed as a tube within the cavity such that when a first end 114A of the aerosol generating consumable is inserted into the cavity, the heater 108 substantially or completely surrounds the portion of the aerosol generating consumable 114 within the cavity 110. The heater 108 may be a wire or ceramic heater, such as a coiled wire heater, or any other suitable type of heater. The heater 108 may include multiple sequentially independently actuable (i.e., powered) heating elements arranged in series along the axial length of the cavity.

[0043] In an alternative embodiment (not shown), the heater may be disposed within the cavity as an elongated penetrating member (e.g., a needle, rod, blade, etc.), and in such an embodiment, the heater may be configured to penetrate the aerosol generating consumable and engage the aerosol generating material when the aerosol generating consumable is inserted into the cavity.

[0044] In another alternative embodiment (not shown), the heater may be in the form of an induction heater. In such an embodiment, a heating element (i.e., a susceptor) may be provided on the consumable, and when the consumable is inserted into the cavity, the heating element is inductively coupled to an inductive element (i.e., an induction coil) within the cavity. The induction heater then heats the heating element by induction.

[0045] From the above description, it will be understood that the heater 108 can be a heating element, such as a heating element and an induction coil. Hereinafter, such a heating element will be referred to as a heater, but it will be understood that this term can refer more generally to any of the heating elements described above, not just heaters.

[0046] The heater 108 is configured to heat the aerosol-generating consumable 114 to a predetermined temperature to generate an aerosol in an aerosolization session. An aerosolization session can be considered when the device is operated to generate an aerosol from the aerosol-generating consumable 114. In an example where the aerosol-generating consumable 114 is a tobacco rod, the aerosol-generating consumable 114 includes tobacco leaves. The heater 108 is configured to heat the tobacco leaves to generate an aerosol without burning the tobacco leaves. That is, the heater 108 heats the tobacco leaves to a predetermined temperature below the combustion point of the tobacco leaves such that a tobacco-based aerosol is generated. It will be readily understood by those skilled in the art that the aerosol-generating consumable 114 does not necessarily have to include tobacco leaves, and that any other material suitable for aerosolization (or vaporization), particularly heating without burning the material, can be used in place of the tobacco leaves.

[0047] Alternatively, the aerosol generating consumable may be a vaporizable liquid, which may be stored in a cartridge container within the aerosol generating device or injected directly into the aerosol generating device.

[0048] The aerosol generating device further includes a battery verification system. The battery verification system includes a battery measurement module 152 and a battery verification module 154. The controller 102 may also be an element of the battery verification system. As described in more detail below, the battery measurement module 152 is configured to perform multiple battery voltage measurements of the battery 104 connected to the aerosol generating device 100. The battery verification module 154 is configured to determine whether a parameter of the battery 104 meets a verification requirement based on the multiple battery voltage measurements. The controller 102 is further configured to set the aerosol generating device to an operable state when the parameter meets the verification requirement, and to set the aerosol generating device to a restricted state when the parameter does not meet the verification requirement. In some examples, the battery measurement module 152 and the battery verification module 154 may be modules included in the controller 102. In other examples, the battery measurement module 152 and the battery verification module 154 may be separate from the controller 102, but in communication with the controller 102.

[0049] It will also be appreciated that the steps performed by the battery measurement module 152 and the battery verification module 154 may be performed by the controller 102 as a single module (e.g., a single microcontroller) or by multiple different modules. That is, a dedicated controller 102, a separate dedicated battery measurement module 152 and a separate dedicated battery verification module 154 are not required, and the above-described aerosol generating device battery verification system may be implemented using one or more suitable processing modules having suitable hardware for performing the steps of the aerosol generating device battery verification process (described below). The controller further configured to set the aerosol generating device to an operational state when the parameters meet the verification requirements and to set the aerosol generating device to a restricted state when the parameters do not meet the verification requirements may not be the main controller that controls the complete operation of the aerosol generating device, but may be a separate controller (in communication with the main controller) used for the battery verification process.

[0050] The controller 102 is configured to control the power flow of the battery 104 during an aerosolization session. The aerosolization session can include a pre-heating phase and a heating phase.

[0051] In the pre-heat phase, the heater 108 associated with the aerosol generating device 100 is heated to a predetermined temperature to generate an aerosol from the aerosol generating consumable 114. The pre-heat phase can be considered the time during which the pre-heat mode is performed, for example, until the heater 108 reaches the predetermined temperature. The pre-heat mode occurs during a first period of an aerosolization session. In one example, the first period can be a fixed, predetermined period. In another example, the first period can vary corresponding to the amount of time required to heat the heater 108 to the predetermined temperature.

[0052] Once the pre-heat phase is complete, the controller 102 exits the pre-heat mode 202 and controls the power system to perform a heating phase 204. In the heating phase, the controller 102 controls the flow of power from the power system to maintain the heater 108 at approximately a predetermined temperature such that an aerosol is generated for inhalation by the consumer. The heating phase can be considered as the time during which the heating mode is performed, for example, the time during which the heater 108 is aerosolizing one (or at least a portion of one) of the aerosol-generating consumables 114 after the pre-heat phase. The controller 102 can control the power system to operate the heating mode for a second period of the aerosolization session. The second period can be predetermined and stored in the controller 102.

[0053] 2A shows an exemplary plot of average power 132 delivered to the heater 108 versus time 134 in an aerosolization session. In the preheat phase, the controller 102 controls the power system to apply power to the heater 108 for a first period 136 until the heater temperature reaches a predetermined temperature. In one example, the predetermined temperature is 230° C. In one example, the first period is 20 seconds. In some examples, the controller 102 is configured to heat the heater 108 to the predetermined temperature within a fixed, predetermined first period. In other examples, the first period varies depending on the time it takes the heater 108 to reach the predetermined temperature.

[0054] Once the heater 108 reaches the predetermined temperature, the controller 102 switches the operating mode to a heating phase for a second period 138 and maintains the heater temperature at approximately the predetermined temperature for the second period 138. In one example, the second period can be 250 seconds. Typically, when maintaining the heater 108 at the predetermined temperature, a lower power level is applied to the heater 108 in the heating phase than the power level applied to the heater 108 to heat the heater 108 to the predetermined temperature in the preheat phase. This can be seen in FIG. 2A in that the power supplied to the heater 108 for the second period 138 is lower than the power supplied to the heater 108 for the first period 136. The power level supplied to the heater 108 can be controlled by various means, such as by adjusting the power output from the battery 104 or by adjusting the on / off periods in a pulse width modulated power flow (as described below).

[0055] Following the aerosolization session, a user of the aerosol generating device may be notified that the aerosolization session has ended, for example by a visual, tactile or audio indicator, so that the user is aware that no more consumables will be aerosolized.

[0056] 2B shows an example circuit diagram of the power system electronics of the aerosol generating device 100. The power system electronics includes the battery 104, the controller 102, and the heater 108. The power system electronics may further include a pulse width modulation (PWM) module 122 controlled by the controller 102. The PWM module 122 is configured to apply pulse width modulation to the power flow from the battery 104 to the heater 108 in an aerosolization session. The controller 102 may control the duty cycle of the pulse width modulation to control the power applied to the heater 108. For example, during pre-heating, a high duty cycle may be applied to rapidly heat up the heater 108.

[0057] In the heating mode, a lower duty cycle can be applied if the heater 108 is maintained at the aerosolization temperature. The PWM module 122 can include a switch, such as a transistor, controlled by the controller 102 to switch between an "on state" and an "off state" each PWM period. A heater temperature sensor or heater temperature sensing circuit 124 can be disposed in the heater 108 or the chamber 110 to monitor the heater temperature. The heater temperature is fed back to the controller 102. If the controller 102 determines that the heater temperature exceeds the aerosolization temperature, it can decrease the power level applied to the heater 108 (e.g., by decreasing the PWM duty cycle). Similarly, if the controller 102 determines that the heater temperature falls below the aerosolization temperature, it can increase the power level applied to the heater 108 (e.g., by increasing the PWM duty cycle).

[0058] A voltage sensor or voltage detection circuit 126 may be connected to the battery 104 to act as a voltmeter and feed back the battery voltage to the controller 102 so that the controller 102 can monitor the state of charge and other battery parameters of the battery 104 by determining the voltage level of the battery 104.

[0059] 2B, the respective connections between the controller 102 and the voltage sensor 126, the PWM module 122, and the heater temperature sensor 124 are represented by arrows for simplicity, however, one of ordinary skill in the art will understand that typical electrical connections between the controller and these elements may be used.

[0060] The aerosol generating device 100 may further include an ambient temperature sensor (not shown) configured to measure the ambient temperature of the air proximate to the aerosol generating device and feed the ambient temperature back to the controller 102.

[0061] In one example, the battery 104 is a rechargeable or secondary battery, such as a lithium ion battery. To improve sustainability, worn-out batteries in the aerosol generating device can be replaced rather than replacing the entire aerosol generating device. When a new battery 104 is connected to the aerosol generating device 100, a battery verification process is performed. Determining that a verified battery is connected to the aerosol generating device is advantageous in ensuring the safety, reliability and quality of the battery.

[0062] FIG. 3 outlines the process of connecting a new battery to an aerosol generating device.

[0063] In step 301, the battery 104 is inserted into the aerosol generating device. For example, this may be accomplished by a device user or technician inserting a new battery 104. In some examples, the new battery 104 may be inserted to replace an old battery that has reached the end of its useful life, or the new battery 104 may be inserted before a user operates a new aerosol generating device for the first time.

[0064] In step 302, the aerosol generating device is connected to an external device.

[0065] In one example, the external device may be a smartphone, a computer, a tablet computer, etc. The connection between the aerosol generating device and the external device may be a wireless connection, for example, using Bluetooth, short-range wireless communication, Wi-Fi, etc. Alternatively, the connection between the aerosol generating device and the external device may be a wired connection, for example, using a USB connection, etc.

[0066] In step 302A, the aerosol generating device initiates a connection to an external device, and in step 302B, the external device responds to establish the connection. Alternatively, in step 302B, the external device may initiate a connection to the aerosol generating device, and in step 302A, the aerosol generating device responds to establish the connection.

[0067] In step 303, an application associated with the aerosol generating device is loaded onto the external device. A user interface is presented that prompts the device operator to input battery information, such as the type of battery 104 inserted into the aerosol generating device. Such information may include the model number and / or manufacturer details of the battery 104.

[0068] Alternatively or additionally, in step 303, using a camera of the external device, the operator may present an interface for receiving input of battery information by scanning a machine-readable label (such as a barcode or QR code) associated with the battery 104. For example, this may be provided on the battery 104 itself or included in packaging associated with the battery 104. That is, the machine-readable label may be used by the application to determine the type of battery 104. The user may then be prompted by the application to confirm that the determined battery 104 is correct.

[0069] In some examples, step 303 may occur before a new battery 104 is placed in the aerosol generating device in step 301.

[0070] In step 304, the application retrieves battery validation parameters based on the received battery information for the type of battery 104 connected to the aerosol generating device, which may be by querying a locally stored database or a remotely stored database accessible to the application, for example.

[0071] In step 305A, the application sends the battery validation parameters to the aerosol generating device using the communication channel established between the two. In step 305B, the aerosol generating device receives the battery validation parameters. The battery validation parameters can then be stored in storage accessible by the controller 102.

[0072] Alternatively, the battery validation parameters may be pre-stored in storage accessible to the controller 102, eliminating the need for connection to an external device.

[0073] In step 306, the controller 102 performs a battery verification process using the battery measurement module 152 and the battery verification module 154, as will be described in more detail with reference to FIG.

[0074] In step 307, if the stored battery 104 is determined to satisfy the battery verification requirements in the battery verification process, the controller 102 sets the aerosol generation device to an operational state. If the stored battery 104 is determined to not satisfy the battery verification requirements in the battery verification process, the controller 102 sets the aerosol generation device to a restricted state. The operational state includes an unlocked state in which an aerosolization session may be performed by the aerosol generation device, and the restricted state includes a locked state in which an aerosolization session may not be performed by the aerosol generation device.

[0075] In this way, if the battery 104 housed in the aerosol generating device is successfully verified, it can be used in an aerosolization session with the aerosol generating device. However, if the battery 104 housed in the aerosol generating device is not verified, it cannot be used in an aerosolization session with the aerosol generating device. This ensures the safety, reliability, and quality of the battery, since only verified batteries can be used in an aerosolization session.

[0076] FIG. 4 illustrates the battery verification process of step 307 of FIG. 3 in more detail.

[0077] In step 401, the battery validation system may determine an ambient temperature in the vicinity of the aerosol generating device using an ambient temperature sensor. When the determined ambient temperature is equal to or greater than the predetermined temperature threshold, the process proceeds to step 402, where the battery measurement module 152 performs a number of battery voltage measurements. When the determined ambient temperature is not equal to or greater than the predetermined temperature threshold, the validation process does not occur and a notification may be presented to an operator of the device to move the device to a warmer environment. This notification may be presented to the operator by an indicator within the aerosol generating device, such as a visual indicator (such as a light source or a display screen), an audible indicator (such as a speaker that emits a noise), or a tactile indicator (such as vibrating in a predetermined manner). In one example, the predetermined temperature threshold may be 15° C. This is advantageous because low temperatures (i.e., below the predetermined temperature threshold) may adversely affect battery chemistry and reduce the reliability of the battery validation process.

[0078] In step 402, the battery validation system may determine the state of charge of the battery 104 by measuring the resting battery voltage as part of a rough state of charge check. In one example, this may be accomplished by the battery measurement module 152 controlling the battery 104 to draw a small or negligible "trickle" current through the device's electronics for a short period of time (e.g., 1 second) (e.g., by activating the Bluetooth module), and then using this small current, the battery voltage is measured with a voltage sensor. The determined battery voltage is converted to a state of charge (SoC) of the battery 104, such as an SoC percentage. The conversion to an SoC percentage may be performed using a look-up table of battery voltages and respective SoC percentages for particular types of batteries 104. This look-up table may be included in the battery validation parameters described in step 305.

[0079] The battery verification process utilizes multiple voltage pulses, and measurements of the battery voltage and other parameters are determined based on these pulses. These battery pulses may be discharge pulses that draw power from the battery 104 or charge pulses that draw power to the battery 104. When the SoC determined in step 402 is equal to or greater than a (first) SoC threshold (e.g., 20%), the battery verification process is performed using a discharge battery pulse from the battery 104 to the heater 108. At low SoC, the battery discharge operation may be less repeatable. Thus, when the determined SoC is less than the SoC threshold, the battery verification process is performed using a charge battery pulse that provides power to the battery 104.

[0080] In some examples, a second SoC threshold may also be implemented. The second SoC threshold may be lower than the first SoC threshold. Below this lower second SoC threshold (e.g., 10%, in some cases 5%), the behavior of the battery becomes non-linear and less repeatable. Thus, when the determined SoC is below the second SoC threshold, the controller 102 may control the device to indicate to the operator, using an indicator built into the device, that the battery 104 needs to be charged before a verification process can be performed to increase the SoC.

[0081] In some examples, the system may be configured to use only discharge pulses or only charge pulses, for example, in aerosol generating devices where a discharge pulse is not suitable, such as where there is no integral heating element.

[0082] The charge pulse to the battery 104 may be applied in two exemplary ways. In a first example, an operator of the device may be prompted by the device interface to connect the device to an external power source. Once the external power source is connected, the battery measurement module 152 controls the power flow from the external power source to the battery 104 such that a charge battery pulse is applied from the external power source to the battery 104. In a second example, where the power system is a dual power system including a battery 104 and a supercapacitor, the battery measurement module 152 controls the power flow from the supercapacitor to the battery 104 such that a charge battery pulse is applied from the supercapacitor to the battery 104.

[0083] In the following description, the battery pulses described are discharging battery pulses from the battery 104 to the heater 108. However, those skilled in the art will readily appreciate that these can be replaced with charging battery pulses (e.g., from an external power source or a supercapacitor in a dual power system) as described above.

[0084] In step 403, the battery measurement module 152 measures the voltage (V before_first_pulse ) is measured. In one example, V before_first_pulse The measurement takes 100 ms or less and may be taken 100 ms (or earlier) before the first pulse is applied so that it is completed before the first pulse is applied. This voltage may be measured by drawing a small or negligible "trickle" current from the battery 104 to the electronics.

[0085] In some examples, the battery voltage measurement in step 402 is V before_first_pulseHowever, using a separate measurement of voltage in step 403 avoids issues with the battery's long time constant affecting the measured voltage.

[0086] In step 404, the battery measurement module 152 controls the battery 104 to apply a first pulse to the heater 108. This first pulse may be applied at a predetermined power level for a predetermined time. In one example, the predetermined power level is 30 W and the predetermined time is 10 seconds. Preferably, the predetermined time should be long enough to encompass information on both the ohmic internal resistance of the battery 104 and the electrochemical and diffusion-related resistances.

[0087] In step 405, the battery measurement module 152 detects a first pulse (I first_pulse ) is measured. This current rate can be considered the average current applied during the first pulse.

[0088] In step 406, the battery measurement module 152 controls the voltage sensor to detect the voltage near the end of the first pulse (V end_first_pulse ) but still measure the battery voltage while the first pulse is being applied. In one example, V end_first_pulse The measurement is taken no sooner than 100 ms before the end of the first pulse.

[0089] The battery measurement module 152 may also control an ambient temperature sensor to measure the temperature during the first pulse.

[0090] In step 407, the battery measurement module 152 measures the first internal resistance (R I_1 ), i.e., the internal resistance based on the first pulse.

[0091] The first internal resistance may be calculated as follows:

[0092]

number

[0093] In step 408, the battery measurement module 152 controls the voltage sensor to measure the resting battery voltage after the first pulse is applied, i.e., the open circuit voltage (V OCV_1 ) is measured. In one example, V OCV_1 is measured 1 second after the end of the first pulse. This voltage can be measured by drawing a small or negligible "trickle" current from the battery 104 to the electronics.

[0094] In step 409, the battery measurement module 152 measures the voltage (V before_second_pulse ) is measured. In one example, V before_second_pulse The measurement of V may take 100 ms or less and may be performed 100 ms (or earlier) before the second pulse is applied so that it is completed before the second pulse is applied. This voltage may be measured by drawing a small or negligible "trickle" current from the battery 104 to the electronics. In some examples, V OCV_1 The value of V before_second_pulse can be used as the value of

[0095] In step 410, the battery measurement module 152 controls the battery 104 to apply a second pulse to the heater 108. This second pulse, like the first pulse, can be applied for a predetermined time and at a predetermined power level.

[0096] In step 411, the battery measurement module 152 measures the rate of current applied from the battery 104 during the first pulse (I second_pulse ). The battery measurement module 152 then integrates the measured current over the duration of the second pulse to calculate the capacity discharged during the second pulse. For example, if the current in a 10 second pulse is 5A, the integrated current (i.e., discharged capacity) is calculated as 50mAh.

[0097] In step 412, the battery measurement module 152 controls the voltage sensor to detect the voltage near the end of the second pulse (V end_second_pulse ) but still measure the battery voltage while the second pulse is being applied. In one example, V end_second_pulse The measurement is taken no sooner than 100 ms before the end of the second pulse.

[0098] In step 413, the battery measurement module 152 measures the second internal resistance (R I_2 ), i.e., the internal resistance based on the second pulse.

[0099] The second internal resistance can be calculated as follows:

[0100]

number

[0101] In step 414, the battery measurement module 152 controls the voltage sensor to measure the resting battery voltage, i.e., the open circuit voltage, after the second pulse is applied (V OCV_2 In one example, V OCV_2 is measured 1 second after the end of the second pulse. This voltage can be measured by drawing a small or negligible "trickle" current from the battery 104 to the electronics.

[0102] Alternatively, V end_second_pulse The value of (V OCV_2 ) after a period of rest (e.g., 1 second), OCV_2 ) may improve the reproducibility of results.

[0103] In step 415, the battery measurement module 152 I_1 and R I_2 Based on the average internal resistance of the battery, R I_average is calculated as follows:

[0104]

number

[0105] In step 416, the battery measurement module 152 calculates the open circuit voltage (V OCV_1 ) and the open circuit voltage (V OCV_2 ) between the pseudo open circuit voltage change (ΔV OCV ) is calculated as follows: ΔV OCV =V OCV_1 -V OCV_2 The values ​​determined in the process described with reference to Figure 4 are then used by the battery validation module 154 to determine whether the parameters of the battery 104 meet validation requirements, such that the aerosol generation device is set to an operable state when the parameters meet the validation requirements, and the aerosol generation device is set to a restricted state when the parameters do not meet the validation requirements, as described below with reference to Figure 5.

[0106] Although two battery pulses are described with reference to Figure 4, in some instances, three or more battery pulses may be used, which may improve the reliability of the averaged internal resistance.

[0107] The process steps performed to determine whether the parameters of the battery 104 meet the validation requirements are described below with reference to FIG.

[0108] In step 501, the battery validation module 154 may check the internal resistance validation requirement. This allows the battery validation module 154 to calculate the average internal resistance (R I_average ) is within the expected range.

[0109] More specifically, the battery validation module 154 compares the measured average internal resistance with a predetermined range derived from the received battery validation parameters. The battery validation parameters may include a look-up table of predetermined internal resistance ranges for a type of battery (e.g., identified by input in step 303 of FIG. 3) inserted into the aerosol generating device at a given ambient temperature and a given SoC. The battery validation module 154 looks up the expected internal resistance range using the SoC determined in step 402 of FIG. 4 and optionally the ambient temperature measured during the first battery pulse. Instead of the ambient temperature measured during the first battery pulse, the expected internal resistance range may be based on an ambient temperature measurement measured at any time during the process (e.g., during the temperature check in step 401 or the second pulse), since the battery temperature is not expected to change significantly during the process and the effect of temperature changes within the operating temperature range (i.e., above a predetermined temperature threshold, e.g., 15° C. or more) on the measurement is expected to be relatively small.

[0110] The expected internal resistance is the expected minimum internal resistance (R I_min ) and expected maximum internal resistance (R I_max ). The battery verification module 154 may include R I_average R I_min Above and R I_max By checking whether R I_average Check whether the internal resistance is within the expected range.

[0111] R I_average R I_min Above and R I_max The internal resistance verification requirement of the battery 104 is met when R I_average R I_min Less than or R I_max If it is greater than 0, then the internal resistance verification requirement of the battery 104 is not met.

[0112] If the internal resistance verification requirement of the battery 104 is not met, the controller 102 sets the aerosol generation device into a restricted, or locked, state and an aerosolization session cannot take place.

[0113] In step 502, the battery verification module 154 may perform a check of the battery voltage change verification requirement. This allows the battery verification module 154 to check the voltage change (ΔV OCV ) is within the expected range.

[0114] More specifically, the battery validation module 154 uses the integrated current during the second pulse (as described with reference to step 411 of FIG. 4) and the ideal available battery capacity of a new battery of the model determined in steps 303, 304 described with reference to FIG. 3 to determine the decrease (or increase, in the case of a rechargeable battery pulse) of the available capacity of the battery 104 during the second battery pulse. This ideal battery voltage may be included in the battery validation parameters provided in step 305. A change in the available capacity of the battery corresponds to a change in the SoC of the battery 104, and thus the battery validation module 154 uses the integrated current and the ideal battery voltage to determine the change in the SoC of the battery 104 during the second pulse.

[0115] In one example, the battery 104 has an ideal available battery capacity of 2000 mAh. If we calculate the integrated current of the second pulse to be 50 mAh, the change in SoC is 2.5%.

[0116] At high charge states, the change in battery voltage corresponding to a determined change in SoC is below the upper limit of the expected voltage change range (ΔV max At low charge states, the change in battery voltage corresponding to a determined change in SoC is below the lower limit of the expected voltage change range (ΔV min ) is defined because the change in battery voltage during a battery pulse is larger for batteries with a higher SoC.

[0117] The received battery validation parameters may include a look-up table of upper and lower limits of the voltage change range of the battery model for a given change in SoC. The battery validation module 154 then calculates a ΔV max and ΔV min The value of can be determined.

[0118] The battery verification module 154 determines whether ΔV OCV value of ΔV max and ΔV min Compare with the value of ΔV OCV is ΔV max Below and ΔV min If it is equal to or greater than ΔV, it is determined that the voltage change verification requirement of the battery 104 is satisfied. OCV is ΔV max is less than or ΔV min When the voltage change verification requirement of the battery 104 is not met.

[0119] In the above example, the battery validation module 154 determines that the change in SoC is 2.5%. Using the look-up table, the battery validation module 154 then determines ΔV max =25mV and ΔV min = 17mV. The change in voltage (ΔV OCV ) is 27mV, then the voltage change is outside the expected range and the voltage change verification requirement is not met.

[0120] When the battery 104 voltage change verification requirement is not met, the controller 102 sets the aerosol generation device into a restricted, or locked, state and an aerosolization session cannot take place.

[0121] In step 503, the battery validation module 154 may perform an estimated battery capacity validation requirement check, whereby the battery validation module 154 estimates the capacity of the battery 104 and checks whether this capacity is within an expected capacity range.

[0122] More specifically, the battery verification module 154 determines whether ΔV OCV Based on the value of and the integrated current of the second pulse, the determined value of the change in SoC as a percentage (ΔSoC) is used to estimate the capacity of the battery 104.

[0123]

number

[0124] where ∫Idt is the integrated current of the second pulse.

[0125] In one example, ΔV OCV is the percentage ΔSoC value for a given SoC range, expressed as ΔV OCV This can be converted to ΔSoC using a look-up table that maps values ​​of ΔV per percentage change in SoC across multiple SoC ranges. OCV It can also be obtained by using a matrix with

[0126] ΔV OCV In the above example where ΔSoC is 27 mV, ΔSoC value is 2.7% (10 mV per 1% SoC), and integrated current is 50 mAh, the battery validation module 154 determines the estimated capacity to be 1852 mAh. OCV is expected to be 25 mV, which means that if the integrated current is 50 mAh, the estimated battery capacity will be 2000 mAh (i.e., the ideal available battery capacity of a new battery 104).

[0127] Upper and lower battery capacity limits define the expected range of battery capacity and may be included in the received battery validation parameters. For example, for a 2000mAh battery, the lower limit may be 1800mAh and the upper limit may be 2200mAh. This accounts for manufacturing variations between batteries of the same model.

[0128] The estimated battery capacity falls within the expected battery capacity range when the estimated battery capacity of the battery 104 is greater than or equal to the lower battery capacity limit and less than or equal to the upper battery capacity limit. The estimated battery capacity of the battery 104 falls outside the expected battery capacity range if the estimated battery capacity is less than the lower battery capacity limit or greater than the upper battery capacity limit.

[0129] When the estimated capacity of the battery 104 falls within the expected battery capacity range, the estimated battery capacity verification requirement is met. When the estimated capacity of the battery 104 is outside the expected battery capacity range, the estimated battery capacity verification requirement is not met.

[0130] When the estimated battery capacity verification requirement is not met, the controller 102 sets the aerosol generation device into a restricted, or locked, state and an aerosolization session cannot occur.

[0131] In the above example, the estimated battery capacity is 1852mAh, the lower limit is 1800mAh, and the upper limit is 2200mAh. In this example, the estimated battery capacity is within the range of expected battery capacity and meets the validation requirement of the estimated battery capacity.

[0132] In step 504, the battery validation module 154 may perform a likelihood validation requirement check. This likelihood check may include determining the estimated capacity and internal resistance (R I_average ) The lower the capacity, the higher the internal resistance of the battery 104 is expected, and the higher the capacity, the lower the internal resistance is expected.

[0133] The battery validation module 154 may determine an expected range of battery capacity for a given internal resistance. For example, the received battery validation parameters may include a look-up table of expected ranges of capacity as a function of the internal resistance of a model of the battery 104 inserted into the aerosol generating device. When the estimated capacity falls within the expected range for the measured internal resistance of the battery 104, the likelihood verification requirement is met. However, when the estimated capacity falls outside the expected range for the measured internal resistance of the battery 104, the likelihood verification requirement is not met. When the likelihood verification requirement is not met, the controller 102 sets the aerosol generating device to a restricted, i.e., locked, state and an aerosolization session cannot be performed.

[0134] As explained above, the battery validation module 154 determines whether the parameters of the battery 104 meet the validation requirements such that the controller 102 sets the aerosol generating device to an operable state when the parameters meet the validation requirements and sets the aerosol generating device to a restricted state when the parameters do not meet the validation requirements. In the example of step 501, the parameters of the battery 104 are determined based on the determined internal resistance (RI_average ), and the verification requirement is that the determined internal resistance falls within the expected internal resistance range. In the example of step 502, the parameter of the battery 104 is the determined voltage change (ΔV OCV ), and the verification requirement is that the determined voltage change of the battery 104 falls within an expected voltage change range. In an example of step 503, the parameter of the battery 104 is an estimated battery capacity, and the verification requirement is an expected capacity range. In an example of step 504, the parameter of the battery 104 is an estimated battery capacity, and the verification requirement is an expected capacity range of the determined internal resistance.

[0135] The battery verification process may include one or more of the checks described with reference to steps 501, 502, 503, and 504. That is, the battery verification requirements may include one or more of the internal resistance verification requirement (501), the voltage change verification requirement (502), the estimated battery capacity verification requirement (503), and the likelihood verification requirement (504). All four of these checks may be used to minimize the number of expected false positives (i.e., batteries passing when they should have failed), thereby reducing the risk. However, not using all four of these checks may reduce the computational complexity by simplifying the process. Whether all or some of the checks are performed may depend on the battery model (e.g., larger capacity batteries are more risky, and therefore more checks are more beneficial) and / or the type of aerosol generating device in which the battery is used (e.g., a device in which the battery is close to the consumer's mouth during use may require more checks).

[0136] When implementing one or more of steps 501, 502, 503, and 504, it will be readily apparent to one of ordinary skill in the art that the one or more implemented steps may be performed in any suitable order and are not limited to the order described with reference to FIG.

[0137] When the verification requirements of each of the implemented battery verification checks are met, the controller 102 controls the aerosol generating device to be in an operational, i.e. unlocked, state in which an aerosolization session may be conducted.

[0138] When at least one of the implemented battery verification requirements is not met, the controller 102 sets the aerosol generation device to a restricted or locked state and an aerosolization session cannot occur. This prompt may be presented to the operator by an indicator within the aerosol generation device, such as a visual indicator (such as a light source or display screen), an audible indicator (such as a speaker emitting a noise), or a tactile indicator (e.g., vibrating in a predetermined manner).

[0139] In some examples, when at least one of the implemented battery verification checks is not met, an operator of the device may be prompted to repeat the battery verification process described with reference to Figures 3, 4 and 5.

[0140] In the iterative battery verification process, when the verification requirements of each of the implemented battery verification checks are met, the controller 102 controls the aerosol generating device to an operational state in which an aerosolization session can be conducted. However, when at least one of the verification requirements is not met in the iterative battery verification process, the controller 102 sets the aerosol generating device to a restricted, i.e., locked, state, in which an aerosolization session cannot be conducted. In this case, the device remains locked until the process is repeated with a new battery and is successful.

[0141] When the aerosol generating device is set to a restricted state, this may be indicated to the operator by an indicator within the aerosol generating device, such as a visual indicator (light source, display screen, etc.), an audible indicator (a speaker that emits sound, etc.) or a tactile indicator (e.g. vibrating in a predetermined manner).

[0142] The measured internal resistance of the battery 104 not being within the expected range (as described with reference to step 501), the measured voltage change of the battery 104 not being within the expected range (as described with reference to step 502), the estimated capacity not being within the expected range (step 503) and / or the estimated battery capacity not being within the expected range for the determined internal resistance (step 504) may suggest that the battery 104 inserted in the aerosol generating device is not the correct model or is an old, abused or used battery. The use of such a battery may adversely affect the safety, reliability and / or quality of operation of the aerosol generating device. Therefore, the controller 102 locks the device when at least one of these checks is not met to prevent the use of the device using such an unqualified or defective battery.

[0143] In the above description, the controller 102 (as well as the battery measurement module 152 and the battery verification module 154) may store instructions for controlling the aerosol generating device and the power system in the manner described. It will be readily apparent to one skilled in the art that the controller 102 (as well as the battery measurement module 152 and the battery verification module 154) may be configured to perform any of the above-described methods in any suitable combination with each other.

[0144] The process steps described herein performed by the controller 102 (and the battery measurement module 152 and battery validation module 154) may be stored in a non-transitory computer readable medium or storage associated with the controller 102 (and the battery measurement module 152 and battery validation module 154). Computer readable media may include non-volatile media and volatile media. Volatile media may include semiconductor memory and dynamic memory, among others. Non-volatile media may include optical and magnetic disks, etc.

[0145] The preceding embodiments in the above description are not limiting, and it will be readily understood by those skilled in the art that the features of each embodiment may be incorporated into other embodiments as appropriate. It will also be understood that the steps of the process described with reference to Figures 3, 4 and 5 do not have to be performed in the order described, but instead may be performed in any suitable order.
