Description

[Technical Field]

[0001] The present invention relates to an aspirated component generating device, a control circuit, a control method and a control program for an aspirated component generating device, and in particular to an aspirated component generating device, a control circuit, a control method and a control program for an aspirated component generating device that can effectively determine a low remaining amount state. [Background technology]

[0002] In recent years, inhalable component generators have been proposed as an alternative to conventional cigarettes, which vaporize or atomize a flavor source or aerosol source such as tobacco to generate inhalable components. Such inhalable component generators include a load that vaporizes or atomizes the flavor source and / or the aerosol source, a power source that supplies power to the load, and a control circuit that controls the operation of the device.

[0003] Patent Document 1 discloses that, in relation to the control of an electronic cigarette, the color of light emitted by an LED is changed depending on the remaining battery power. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] US Patent Application Publication No. 2014 / 0053856 Summary of the Invention [Problem to be solved by the invention]

[0005] In a configuration like the one described in Patent Document 1, where the color of the light changes depending on the remaining battery charge, the user can check the color of the LED to know the current remaining battery charge. However, it is unclear whether the configuration in this document detects the remaining battery charge based on the open-circuit voltage value, the closed-circuit voltage value, or both. The closed-circuit voltage is affected by the internal resistance of the power source, so its value differs from the open-circuit voltage. This means that the derived battery voltage value can vary depending on the ratio of the open-circuit voltage and the closed-circuit voltage. Because the derived battery voltage value is prone to deviating from the true value, there is a problem in that the accuracy of determining a low battery charge state decreases.

[0006] Therefore, an object of the present invention is to provide an aspirated component generating device, a control circuit, a control method for an aspirated component generating device, and a control program that can accurately obtain the battery voltage value and effectively determine a low remaining charge state.

[0012] (Terminology explanation) An "inhalable component generator" refers to a device that vaporizes or atomizes a flavor source or aerosol source, such as tobacco, to generate an inhalable component. It may be a product formed in a single housing, or it may be a product consisting of multiple components (units) connected together and used as a single product. A "power source" refers to a source of electrical energy, including batteries and capacitors. Examples of batteries include secondary batteries such as lithium-ion secondary batteries. A secondary battery may include a positive electrode, a negative electrode, a separator separating the positive and negative electrodes, and an electrolyte or ionic liquid. The electrolyte or ionic liquid may be, for example, a solution containing an electrolyte. In a lithium-ion secondary battery, the positive electrode is composed of a positive electrode material such as lithium oxide, and the negative electrode is composed of a negative electrode material such as graphite. The electrolyte may be, for example, a lithium salt organic solvent. Examples of capacitors include electric double-layer capacitors (EDLCs). Note that power sources are not limited to these, and other secondary batteries, such as nickel-metal hydride secondary batteries, or primary batteries may also be used. The term "load" refers to anything in an electrical circuit that consumes energy, but in this specification, it primarily refers to anything that generates the attractant. Loads include heating means such as heaters, including, for example, electrical resistance heaters and induction heating (IH) means. They also include means for generating attractant using ultrasound, means for generating attractant using piezoelectric elements, and sprayers. The term "loads" refers to not only those that generate attractant, but also elements that generate light, sound, or vibration, for example. If a communication module or other device is installed, it may also be included in the loads. On the other hand, although microcomputers and other components in an electrical circuit are technically elements that generate energy through the flow of minute currents, they are not included in the loads in this specification. "Aerosol" means a dispersion of fine liquid or solid particles in a gas. Regarding the "deterioration diagnosis function," typical battery deterioration includes, for example, a decrease in capacity and an increase in resistance. For example, the deterioration diagnosis function may acquire a power supply voltage value to diagnose a decrease in capacity and determine whether the value is equal to or greater than the lower limit of a predetermined reference range. [Effects of the Invention]

[0013] According to the present invention, it is possible to provide an aspirated component generating device, a control circuit, a control method for an aspirated component generating device, and a control program that can accurately obtain the battery voltage value and effectively determine a low remaining charge state.

[0015] Embodiments of the present invention will be described below with reference to the drawings. It should be noted that the specific structures and electrical circuits described below are merely examples of the present invention, and the present invention is not necessarily limited thereto. In the following description, structural parts having essentially the same functions will be denoted by the same or corresponding reference numerals, but in some cases the reference numerals may be omitted for convenience of explanation. While some configurations of the device may be depicted differently in one drawing from another, please note that these are not essential differences in the present invention, and either configuration may be adopted.

[0016] 1.Device configuration 1 and 2, the aspirated component generator 100 of this embodiment includes a power supply unit 110 and a cartridge unit 120 that is detachably attached to the power supply unit 110. Although this embodiment shows an example in which the power supply unit 110 and the cartridge unit 120 are configured as separate units, the aspirated component generator of the present invention may also have these configured as an integrated unit.

[0017] The overall shape of the inhaled component generator 100 is not particularly limited and may take various forms. For example, as shown in FIG. 2, the inhaled component generator 100 may be formed in a rod-like shape. Specifically, the inhaled component generator 100 is formed in a single rod shape by axially connecting the power supply unit 110 and the cartridge unit 120. The rod-like overall shape of the device allows the user to inhale with a sensation similar to smoking a conventional cigarette. In the example of FIG. 2, the end on the right side of the figure is the mouthpiece 142, and the opposite end is provided with a light-emitting unit 40 that emits light depending on the operating state of the device. During use, a mouthpiece (not shown) may be attached to the mouthpiece 142 to inhale. The specific dimensions of the device are not particularly limited. For example, the diameter may be approximately 15 mm to 25 mm, and the overall length may be approximately 50 mm to 150 mm, so that the device can be held by hand.

[0018] (Power supply unit) 1, the power supply unit 110 includes a case member 119, a power supply 10 provided therein, a suction sensor 20, a control circuit 50, and the like. The power supply unit 110 also includes a push button 30 and a light-emitting unit 40. Note that not all of these elements are essential components of the suction component generator 100, and one or more may be omitted. Alternatively, one or more may be provided in the cartridge unit 120 rather than in the power supply unit 110.

[0019] The case member 119 may be a cylindrical member, and although there are no particular limitations on the material, it may be made of metal or resin.

[0020] The power supply 10 may be a rechargeable secondary battery such as a lithium ion secondary battery or a nickel-metal hydride (Ni-MH) battery. The power supply 10 may be a primary battery or a capacitor instead of a secondary battery. The power supply 10 may be provided in a replaceable manner in the power supply unit 110, or may be built-in. The number of power supplies 10 may be one or more.

[0021] The suction sensor 20 may be, for example, a sensor that outputs a predetermined output value (e.g., a voltage value or a current value) according to the flow rate and / or flow velocity of the gas passing therethrough. Such a suction sensor 20 is used to detect a puffing action (inhalation action) by the user. Various types of suction sensors can be used as the suction sensor 20, and examples thereof include a condenser microphone sensor and a flow rate sensor.

[0022] The push button 30 is a button operated by the user. Although it is expressed as a "push button," it is not limited to a button that displaces when pressed, and may be an input device such as a touch button, for example. The location of the push button 30 is also not particularly limited, and it may be provided at any location on the housing of the aspirated component generation device 100. As an example, the push button 30 may be provided on the side of the case member 119 of the power supply unit 110 to make it easier for the user to operate. Multiple push buttons 30 (input devices that accept input from the user) may be provided.

[0023] The light-emitting unit 40 includes one or more light sources (e.g., LEDs) and is configured to emit light in a predetermined light pattern at a predetermined timing. For example, in one embodiment, it is preferable that the light-emitting unit 40 be configured to emit light in multiple colors. Examples of the role of the light-emitting unit 40 include informing the user of the device's operating status or informing the user when an abnormality occurs. In light of these roles, the notification device provided in the inhalable component generator 100 may also include one or a combination of other devices, such as a vibration device that generates vibrations, an acoustic device that generates sound, or a display device that displays predetermined information. For example, the light-emitting unit 40 may be provided at an end of the power supply unit 110. In the inhalable component generator 100, if the light-emitting unit 40 provided at the end opposite the end where the mouthpiece 142 is provided emits light in response to the user's puffing, the user can inhale the inhalable component with the same ease as a conventional cigarette.

[0024] 3 is a block diagram showing an example of the configuration of the aspirated component generation device 100. As shown in FIG. 3, the aspirated component generation device 100 also includes a temperature sensor 61, a voltage sensor 62, and the like in addition to the above.

[0025] The temperature sensor 61 is used to acquire or estimate the temperature of a predetermined object within the aspirated component generation device 100. The temperature sensor 61 may measure the temperature of the power source 10, or may measure the temperature of an object other than the power source 10. Furthermore, instead of providing a dedicated temperature sensor, a temperature detector incorporated into a predetermined component of an electrical circuit may be used. Specific processing based on the output of the temperature sensor 61 will be described later. The temperature sensor 61 may be, but is not limited to, a thermistor, a thermocouple, a resistance temperature band, an IC temperature sensor, or the like. The number of temperature sensors 61 is not limited to one, and multiple sensors may be provided.

[0026] The voltage sensor 62 is, for example, for measuring the power supply voltage. A sensor for measuring a predetermined voltage other than the power supply voltage may also be provided. Specific processing based on the output of the voltage sensor 62 will be described later. The number of voltage sensors 62 is not limited to one, and multiple sensors may be provided.

[0027] If necessary, the aspirated component generating device 100 may further be provided with a wireless communication device (not shown) and / or a communication port (not shown) that enables connection to an external device. For example, the device may be configured so that information regarding the power supply status, information regarding aspirating, etc., is transmitted to the external device via these.

[0028] (Cartridge unit) The cartridge unit 120 is a unit that has an inhalation component source therein, and as shown in Figures 1 and 4, includes a case member 129, a reservoir 123, a flavor unit 130, and a load 125 that vaporizes or atomizes the inhalation component source. Note that not all of the above elements are necessarily essential components of the inhalation component generation device 100. In particular, in this embodiment, an example will be described in which both the reservoir 123 for generating an aerosol and the flavor unit 130 for generating a flavor component (details below) are provided, but only one of these may be provided.

[0029] As an example of the general function of cartridge unit 120, in the first stage, the aerosol source stored in reservoir 123 is vaporized or atomized by the operation of load 125. Then, in the second stage, the generated aerosol flows through flavor unit 130, imparting flavor components to the aerosol, and is finally inhaled into the user's mouth.

[0030] The case member 129 (see FIG. 4) may be a cylindrical member, and its material is not particularly limited, but may be made of metal or resin. The cross-sectional shape of the case member 129 may be formed to be the same as that of the case member 119 of the power supply unit 110. As mentioned above, the cartridge unit 120 is connectable to the power supply unit 110. Specifically, as an example, the cartridge unit 120 may have a connection portion 121 at one end physically connected to the connection portion 111 at one end of the power supply unit 110. In FIG. 4, the connection portion 121 is depicted as a threaded portion, but the present invention is not necessarily limited to this. Instead of connection by a threaded portion, the connection portions 111 and 121 may be magnetically coupled. When the connection portions 111 and 121 are connected to each other, an electrical circuit on the power supply unit 110 side and an electrical circuit on the cartridge unit 120 side may be electrically connected (details will be described later).

[0031] As shown in Fig. 4, a cylindrical member forming an inlet hole 121a for taking air into the unit is provided inside the connection part 121 so as to extend in the axial direction of the case member 129. Also, one or more holes 121b are formed at the connection part 121 so as to extend in the radial direction, and outside air is taken in through these holes 121b. The inlet hole may be provided in the connection part 111 of the power supply unit 110 instead of the connection part 121 of the cartridge unit 120. Also, the inlet hole may be provided in both the connection part 111 of the power supply unit 110 and the connection part 121 of the cartridge unit 120.

[0032] The reservoir 123 is a container for storing an aerosol source that is liquid at room temperature. The reservoir 123 may be, for example, a porous body made of a material such as a resin web. The aerosol source may also be solid at room temperature. Here, the description will focus on an embodiment in which the aerosol source is stored in the reservoir 123, but the reservoir 123 may also be a embodiment in which a flavor source is stored.

[0033] Examples of aerosol sources include polyhydric alcohols such as glycerin and propylene glycol, and water. The aerosol source itself may contain flavor components. Alternatively, the aerosol source may contain tobacco raw materials or extracts derived from tobacco raw materials that release flavor components when heated.

[0034] The load 125 may be, for example, a heat generating element such as a heater, an ultrasonic element that generates, for example, microdroplets by ultrasonic waves, or the like. Examples of the heat generating element include a heating resistor (e.g., an electric heating wire), a ceramic heater, and an induction heater. The load 125 may also be one that generates flavor components from a flavor source.

[0035] To explain the peripheral structure of the reservoir 123 in more detail, in the example of FIG. 4, a wick 122 is provided in contact with the reservoir 123, and a load 125 is provided to surround a portion of the wick 122. The wick 122 is a member that draws the aerosol source from the reservoir 123 by utilizing capillary action. The wick 122 may be made of, for example, glass fiber or porous ceramic. When a portion of the wick 122 is heated, the aerosol source held therein is vaporized or atomized. Note that in a configuration in which a flavor source is stored in the reservoir 123, the flavor source is vaporized or atomized.

[0036] In the example of Fig. 4, the load 125 is provided as a heating wire formed in a spiral shape. However, the load 125 is not necessarily limited to a specific shape and can be any shape as long as it can generate an attraction component.

[0037] The flavor unit 130 is a unit that contains a flavor source. A variety of specific configurations can be adopted, and the specific configuration is not particularly limited. For example, the flavor unit 130 may be provided as a replaceable cartridge. In the example of FIG. 4, the flavor unit 130 has a cylindrical body 131 that is filled with a flavor source. More specifically, the cylindrical body 131 includes a membrane member 133 and a filter 132.

[0038] The flavor source is composed of raw material pieces of plant material that impart flavor components to the aerosol. The raw material pieces that make up the flavor source can be formed from a granular product of tobacco material such as shredded tobacco or tobacco raw material. Alternatively, the flavor source can be a granular product of tobacco material formed into a sheet. The raw material pieces that make up the flavor source may also be formed from plants other than tobacco (e.g., mint, herbs, etc.). The flavor source may also be imparted with a flavoring such as menthol.

[0039] In this embodiment, as shown in FIG. 4, a rupture section 127a is provided inside the cartridge unit 120, and the rupture section 127a is configured to rupture the membrane member 133 of the flavor unit 130. Specifically, the rupture section 127a is a cylindrical hollow needle, and is configured so that its tip side can pierce the membrane member 133. The rupture section 127a may be held by a partition member 127b that separates the cartridge unit 120 and the flavor unit 130. The partition member 127b is made of, for example, polyacetal resin. By connecting the rupture section 127a and the flavor unit 130, a flow path is formed inside the cartridge unit 120, and aerosol, air, etc. flow through this flow path.

[0040] Specifically, as shown in FIG. 4, the flow path is composed of an inlet 121a provided inside the reservoir 123, an internal passage 127c connected thereto, a passage in the destruction section 127a, a passage in the flavor unit 130, and a suction hole 141 (details below). In one embodiment, it is preferable that the interior of the hollow needle, which is the destruction section 127a, is provided with a mesh that is coarse enough to prevent the flavor source from passing through. The inhaled component generation device 100 may include a suction port section 142 having a suction hole 141 through which the user inhales the inhaled component. The suction port section 142 may be configured to be detachable from the inhaled component generation device 100, or may be configured as an integral, inseparable unit.

[0041] The flavor unit may have a structure as shown in FIG. 5 . In this flavor unit 130′, a flavor source is disposed within a cylindrical body 131′. One open end of the cylindrical body 131′ is provided with a membrane member 133′, and the other open end is provided with a filter 132′. The cylindrical body 131′ may be replaceable with respect to the cartridge unit 120. Other structural components in FIG. 5 are similar to those in FIG. 4 , and therefore redundant description will be omitted. In the example of FIG. 5 , a gap is formed between the outer peripheral surface of the cylindrical body 131′ of the flavor unit 130′ and the inner peripheral surface of the case member 129. However, such a gap may not be formed. In this case, all inhaled gas passes through the interior of the cylindrical body 131′. Various types of flavor units 130′ containing different flavor sources are commercially available, and they may be configured to be set in the inhalable component generator 100 according to the user's preference and inhaled. The flavor unit 130′ may be configured so that an end of the flavor unit 130′ protrudes and is exposed from the case member 129 when the flavor unit 130′ is connected to the cartridge unit 120. With this configuration, the replaceable flavor unit 130′ serves as the mouthpiece 142, allowing the user to use the inhaled component production device 100 hygienically without touching the case member 129 during inhalation.

[0042] (Control circuit) 3, the control circuit 50 of the aspirated component generator 100 may include a processor having a memory and a CPU (neither of which are shown), various electrical circuits, etc. The processor may be any device that performs various processes, regardless of its name, and may be, for example, what is called an MCU (Micro Controller Unit), a microcomputer, a control IC, a control unit, etc. The control circuit 50 may be configured such that a single control circuit controls the functions of the aspirated component generator 100, or may be configured such that multiple control circuits share and perform various functions.

[0043] In the following, an example will be described in which the charger 200 is provided separately from the aspirated component generator 100. In this case, a first control circuit is provided on the device side, and a second control circuit is provided on the charger side, with each control circuit performing a predetermined function. Alternatively, as another example of the aspirated component generator 100 configuration, the charger function can be built into the device body, in which case they can be configured as a single control circuit. Thus, in the present invention, multiple control circuits may be used depending on the physical configuration of the device, and the control circuits that perform various controls can be changed as appropriate.

[0044] (Electrical circuit configuration) An example of a specific circuit configuration of the aspirated component generation device 100 of this embodiment will be described below with reference to the drawings. As shown in Fig. 6, the overall electrical circuit of the aspirated component generation device 100 is provided such that a circuit on the power supply unit 110 side and a circuit on the cartridge unit 120 side can be connected to each other.

[0045] A load 125 is provided in the circuit of the cartridge unit 120, and both ends of the load 125 are connected to a pair of electrical terminals 121t. In this embodiment, the pair of electrical terminals 121t constitutes a connection part 121 from the viewpoint of electrical connection.

[0046] The circuit of the power supply unit 110 includes a control unit (control IC) 50A, a power supply 10, a protection circuit 180, a first switch 172, a second switch 174, etc. As shown schematically in Fig. 7, the circuit of the power supply unit 110 is connected to the circuit of the cartridge unit 120 described above, and is also configured to be connectable to the circuit of the charger 200 (described in detail later).

[0047] 6, in the circuit of power supply unit 110, the high-potential side of power supply 10 and control unit 50A are connected by path 110a, path 110b, and path 110c. Path 110a connects the high-potential side of power supply 10 and node 156, path 110b connects node 156 and node 154, and path 110c connects node 154 and control unit 50A. Path 110d is drawn out from node 154, and path 110d connects node 154 and protection circuit 180. Two switches 172 and 174 are provided on path 110d.

[0048] A resistor 161 is provided in the path 110a between the point connected to the high-potential side of the power supply 10 and the protection circuit 180. A first resistor 150 is provided in the path 110b, and a second resistor 152 is provided in the path 110c. In this example, one of a pair of electrical terminals 111t is connected to a node 156, and the other is connected to a node 154. A path 110e connects the control unit 50A to a point on the path 110d between the second switch 174 and the protection circuit 180, and a resistor 162 is provided on this path 110e. The protection circuit 180 and the path 110a are also connected by a path 110f, and a capacitor 163 is provided on this path 110f. In one embodiment, although not limited thereto, it is preferable that the electrical resistance values ​​of the first resistor 150 and the second resistor 152 are known. The first resistor 150 may be a known resistor to the control unit 50A or an external unit. Similarly, the second resistor 152 may be a resistor known to the control unit 50A or the external unit. The electrical resistance value of the first resistor 150 and the electrical resistance value of the second resistor 152 may be the same.

[0049] The first switch 172 switches the electrical connection state between the power supply 10 and the load 125. The first switch 172 may be configured with, for example, a MOSFET. The first switch 172 may function as a so-called discharge FET. The ON / OFF of the first switch 172 is controlled by the control unit 50A. Specifically, when the first switch 172 is closed (i.e., turned ON), power is supplied from the power supply 10 to the load 125, and when the switch 172 is opened (i.e., turned OFF), no power is supplied.

[0050] The load 125 may be configured to be subjected to PWM (Pulse Width Modulation) control by controlling the opening and closing of the first switch 172. However, PFM (Pulse Frequency Modulation) control may be performed instead of PWM control. The duty ratio in PWM control and the switching frequency in PFM control may be adjusted by various parameters including the voltage value of the power supply 10. The specific circuit configuration of the first switch 172 is not necessarily limited to the one described below, but may include a parasitic diode. This parasitic diode may reverse the direction of current flow from the power supply 10 through the node 154 when an external unit such as a charger is not connected, for example.

[0051] The second switch 174 is electrically connected to the node 154 via the first switch 172. The second switch 174 may also be configured, for example, by a MOSFET and controlled by the control unit 50A. Specifically, the second switch 174 may be capable of transitioning between an open state in which a current flows from the low potential side to the high potential side of the power supply 10 and a closed state in which a current flows from the low potential side to the high potential side of the power supply 10. Note that the second switch 174 may also have a parasitic diode that reverses the direction of the flow of the charging current that charges the power supply 10.

[0052] In the circuit configuration described above, the current from power supply 10 flows back to power supply 10 mainly through node 156, load 125, node 154, and switch 172 in this order, thereby heating load 125. Note that a portion of the current from power supply 10 passes through resistor 150, but by setting the resistance value of resistor 150 to be sufficiently larger than the resistance value of load 125, the loss caused by the current flowing through resistor 150 can be reduced.

[0053] (Charger circuit configuration) Next, an example of a specific circuit configuration on the charger 200 side will be described below with reference to Fig. 8. In Fig. 8, the circuit configuration on the power supply unit 110 side is the same as in Fig. 6.

[0054] The external shape of charger 200 is not limited in any way and can be any shape, but as one example, charger 200 may be shaped like a USB memory stick having a USB terminal connectable to a USB (Universal Serial Bus) port. As another example, charger 200 may be shaped like a cradle that holds a power supply unit or a case that houses a power supply unit inside. When charger 200 is configured in a cradle or case shape, external power supply 210 is preferably built into charger 200, and the size and weight of charger 200 are preferably portable by the user.

[0055] As shown in FIG. 8 , the circuitry of charger 200 includes a charging control unit (charging control IC) 250, an inverter 251 that converts AC to DC, and a converter 253 that increases or decreases the voltage output by inverter 251. Charger 200 may include a built-in charging power supply 210 for supplying charging power, or may use another device or a commercial power source as an external power source. Note that if charging power supply 210 is built into charger 200 and outputs DC, inverter 251 may be omitted. Charger 200 also includes a current sensor 230 that reads the value of the charging current supplied to power source 10, and a voltage sensor 240 that acquires the voltage difference between a pair of electrical terminals 211t (connection portion 211). Voltage sensor 240 may be configured to cooperate with control circuit 50 and switches 172 and 174 to acquire the value of the voltage applied to first resistor 150.

[0056] The charging control unit 250 may have one or more functions, such as detecting the connection of the power supply unit 110, determining the type of the object to be connected, and controlling charging based on the output value of a current sensor and / or the output value of a voltage sensor. However, the control unit 50A of the aspirated component production device 100 may be configured to perform one or more of these functions, rather than the charger 200. Details of the above functions will be described later.

[0057] 2. Operation control The functions of the aspirated component generating device 100 include, for example, the following: (a1) Power supply control (a2) Light emission control (a3) Operation control based on power supply temperature (a4) Deterioration diagnosis function (b1) Charger connection detection (b2) Charging control The following explains each in order.

[0058] (a1) Power supply control The control circuit 50 has a function of supplying power to the load 125 based on a request signal from a request sensor. The request sensor is, for example, a device that can output a signal requesting operation of the load 125. Specifically, the request sensor may be, for example, a push button 30 pressed by a user or a suction sensor 20 that detects the user's suction operation. In other words, the control circuit 50 may be configured to perform a predetermined operation when the push button 30 is pressed and / or when the detection result of the suction sensor 20 is used as a trigger. A value related to the amount of operation of the load 125 may be measured by a predetermined counter.

[0059] The termination of power supply may be controlled as follows. That is, the control circuit 50 determines whether the timing to terminate power supply to the load 125 has been detected, and if so, terminates power supply. The control circuit 50 may measure values ​​related to the operation amount of the load 125 (such as the amount of power supplied to the load, the operation time of the load, and / or the amount of suction component source consumed). More specifically, the termination timing of power supply may be the timing when the suction sensor 20 detects the end of the operation for using the load. For example, it may be the timing when the user detects the end of the suction operation. Alternatively, power supply may be terminated when it detects that the push button 30 has been released.

[0060] Furthermore, power supply may be terminated based on a cutoff time. That is, power supply may be terminated when it is detected that a predetermined cutoff time has elapsed during power supply. To achieve control based on the cutoff time, a cutoff time (in the range of 1.0 to 5.0 seconds, preferably 1.5 to 3.0 seconds, more preferably 1.5 to 2.5 seconds) may be set based on the time required for a typical user to perform one inhalation action.

[0061] An example of the cutoff time will be briefly described with reference to FIG. 9. The horizontal axis represents time, with the upper graph representing changes in the suction amount or suction speed, and the lower graph representing the discharge FET signal (corresponding to the voltage waveform supplied to the load). In this example, power supply to the load is initiated when it is determined that suction has started based on the output (suction amount or suction speed) of the suction sensor 20. In the figure, time t2 represents the timing at which suction has ended. When a cutoff time is used, even if suction is actually determined to have been completed at time t2, power supply is forcibly terminated after a predetermined cutoff time (here, time t1) has elapsed. By setting a cutoff time in this manner, it is possible to reduce variations in the amount of aerosol generated per power supply, thereby improving the user's aerosol inhalation experience. Furthermore, by suppressing long-term continuous power supply to the load 125, the life of the load 125 can be extended.

[0062] The control circuit 50 may be configured to acquire values ​​related to the load's operation amount in one puffing operation and derive a cumulative value of the acquired values. That is, the control circuit 50 measures the amount of power supplied to the load and the load's operation time in one puffing operation. The operation time may be the total time during which the power pulse is applied. Alternatively, the control circuit 50 may be configured to measure the amount of the inhalation component source consumed in one puffing operation. The amount of the inhalation component source consumed can be estimated, for example, from the amount of power supplied to the load. When the inhalation component source is a liquid, the amount of the inhalation component source consumed may be derived based at least on the weight of the inhalation component source remaining in the reservoir, or based at least on the output of a sensor measuring the liquid level of the inhalation component source. The load's operation amount in one puffing operation may be derived based at least on the load temperature (e.g., the maximum temperature of the load in the puffing operation and / or the amount of heat generated by the load).

[0063] A specific example of operation based on the output of the suction sensor will be further explained with reference to FIG. 10. FIG. 10 is a diagram schematically illustrating the relationship between the output value of the suction sensor and the voltage supplied to the load. In this example, the control circuit 50 detects whether the output value of the suction sensor is equal to or greater than a first reference value O1, and if so, determines that a suction operation is occurring. This timing triggers a request for power supply. The control circuit 50 then detects whether the output value of the suction sensor is equal to or less than a second reference value O2, and if so, determines that it is time to end power supply.

[0064] For example, the control circuit 50 may be configured to detect suction only when the absolute value of the output value of the suction sensor is equal to or greater than a first reference value O1. Since the detection of the second reference value O2 is for executing a transition from a state in which the load is already operating to a state in which it is not operating, the first reference value O2 may be smaller than the second reference value O1.

[0065] Regarding the operation of the load, for example, when the power supply voltage value is relatively high, the pulse width in PWM control may be narrowed (see the middle part of the graph in FIG. 10 ), and when the power supply voltage value is relatively low, the pulse width may be widened (see the lower part of the graph). The power supply voltage value generally decreases as the charge level of the power supply decreases. Therefore, in one embodiment, it is preferable to adjust the amount of power according to the power supply voltage value at each time. Using such a control method, for example, the effective value of the voltage (power) supplied to the load can be made the same or substantially the same when the power supply voltage value is relatively high and when it is relatively low. It is also preferable to perform PWM control with a higher duty ratio when the power supply voltage value is low. Using such a control method, it is possible to appropriately adjust (e.g., substantially equalize) the amount of aerosol generated during puffing, regardless of the remaining power level. Maintaining a substantially uniform amount of aerosol generated during puffing can improve the user's aerosol inhalation experience.

[0066] (a2) LED light emission control, etc. The aspirated component generator of this embodiment may operate the light emitting unit 40 (see FIG. 1, etc.) as follows. However, as mentioned above, instead of light emission, it is also possible to notify the user by notification means such as sound or vibration. FIG. 11 is a flowchart showing a specific example of the operation of the aspirated component generator 100.

[0067] First, in step S101, control circuit 100 (see FIG. 3) detects whether suction has started. If the start of suction is not detected, step S101 is repeated, and if the start of suction is detected, the process proceeds to step S102.

[0068] Next, in step S102, the power supply voltage value V batt The power supply voltage value V is obtained and it is determined whether or not the value exceeds the discharge end voltage value of the power supply 10 (for example, 3.2 V). batt If the voltage is equal to or less than the discharge cut-off voltage, it means that the remaining power supply is not sufficient, so in step S122, the light-emitting unit 40 is made to emit light in a predetermined mode. Specifically, for example, the light may be made to flash in red.

[0069] In step S102, the power supply voltage value V batt If it is determined that the remaining amount is sufficient because the discharge end voltage is greater than the discharge end voltage, then in step S103, it is determined that the discharge end voltage<the power supply voltage value V batt Determine whether or not the power supply voltage V is less than or equal to (full charge voltage - Δ), where Δ is a positive value. batt Whether or not power is supplied at a duty ratio of 100% is determined depending on whether the value is within this range, as described below. If the value is within this range, power is supplied at a duty ratio of 100% in step S104. As an example, and not a limitation, the light-emitting unit 40 may be lit in blue (step S105).

[0070] On the other hand, in step S103, the power supply voltage value V batt is not within the above range, then in step S123, (full charge voltage - Δ) < power supply voltage value V battIf the voltage is within this range, constant power control is achieved by supplying power using PWM control in step S124.

[0071] In this embodiment, the suction time T L is reset to "0", and then the suction time T L is updated by adding Δt in step S107.

[0072] Next, in step S108, it is determined whether or not the end of suction has been detected. If the end of suction has been detected, the process proceeds to step S109, where power supply to the load is stopped. On the other hand, if the end of suction has not been detected, the suction time T L If it is determined that the time has elapsed since the start of the load detection has reached the predetermined upper limit time, the process proceeds to step S109, where the power supply to the load is stopped. Then, in step S110, the light-emitting unit 40 is turned off.

[0073] In step S111, the cumulative time T A is updated. That is, the accumulated time T A This suction time T L Add the new accumulated time T A Next, in step S112, the cumulative time T A If the time has not been exceeded, it is determined that the device can be used continuously, and the sequence returns to step S101. On the other hand, if the integrated time T A If the inhalation time has elapsed, it is assumed that the flavor source in the flavor unit 130 or the aerosol source in the reservoir 123 is insufficient or depleted, and power supply to the load is prohibited in step S115, which will be described later.

[0074] On the other hand, if this time has been exceeded, step S113 detects whether inhalation has started, and step S114 determines whether inhalation has continued for a predetermined time (e.g., 1.0 second). Even if inhalation has continued for more than the predetermined time, power supply to the load is prohibited in step S115. In this case, to notify the user that power supply is prohibited, the light-emitting unit emits light in a predetermined mode (e.g., blinks blue) in step S116, and after a certain time has passed, the power supply prohibition state is released in step S117. Note that, instead of the passage of a certain time, the condition for releasing the power supply prohibition state in step S117 may be replacement of the flavor unit 130 or cartridge unit 120 with a new one or refilling of the flavor source or aerosol source.

[0075] According to the above-described series of operations, the operation mode of the load is changed appropriately depending on the remaining power level of the power source, and the user can also understand the current operating state of the aspirated component generation device through the light emitting unit 40.

[0076] (a3) Operation control based on power supply temperature The aspirated component generating device 100 of this embodiment is batt It may be configured to determine whether the temperature is within a predetermined temperature range, and perform or not perform a predetermined operation based on the result. Specific examples of temperature ranges are shown in Fig. 12. In this example, first to fourth temperature ranges are set. Note that instead of all four, only one, two, or three of these may be set.

[0077] The first temperature range is a temperature range related to permission of a SOH (State of health) diagnosis indicating the health state of the power supply, and includes an upper limit temperature T1a and a lower limit temperature T1b. Specific numerical values ​​of the upper limit temperature and the lower limit temperature can be set as appropriate. The unit of SOH may be [%]. In this case, the SOH when the battery is new may be set to 100 [%], and the SOH when the battery has deteriorated to the point where charging and discharging is difficult may be set to 0 [%]. As another example, the value obtained by dividing the current full charge capacity by the full charge capacity when the battery was new may be used as the SOH.

[0078] The upper limit temperature T1a is not limited to any particular value, but may be set below or equal to the temperature at which the structure and / or composition of the power supply's electrodes or electrolyte may change (or the temperature at which such a change becomes significant), or the temperature at which decomposition gas may be generated (or the temperature at which such generation becomes significant), taking into consideration such factors. If the SOH is obtained at a temperature equal to or higher than the upper limit temperature T1a, it will be difficult to obtain an appropriate degradation diagnosis result due to the strong influence of temperature. As an example, the temperature T1a may be 60°C. By setting the temperature range in this way, degradation diagnosis will be performed within a range where no structural changes occur in the power supply or where decomposition gas generation is suppressed, making it possible to obtain an appropriate degradation diagnosis result.

[0079] The lower limit temperature T1b may be set higher or higher, for example, taking into consideration the temperature at which output degradation due to temperatures lower than the SOH may become dominant (or the temperature at which this effect becomes more pronounced). Temperature T1b is, for example, 15°C. To obtain the SOH, an index indicating capacity degradation of the power supply 10, such as output degradation, is generally used. Therefore, in a temperature range where output degradation is caused by factors other than the SOH, it is difficult to obtain an appropriate degradation diagnosis result. In other words, if degradation diagnosis is permitted only when the power supply temperature is within the first temperature range defined by the upper limit temperature T1a and the lower limit temperature T1b, the influence of the power supply temperature on the degradation diagnosis result can be minimized. Therefore, it is possible to obtain an appropriate degradation diagnosis result.

[0080] The second temperature range is a temperature range for permitting discharge of the power supply, and includes an upper limit temperature T2a and a lower limit temperature T2b. The specific values ​​of the upper limit temperature and the lower limit temperature can be set as appropriate. The upper limit temperature T2a may be set, for example, based on the same criteria as the upper limit temperature T1a of the first temperature range. As an example, the temperature T2a is 60°C. As another example, the upper limit temperature T2a may be different from the upper limit temperature T1a. The lower limit temperature T2b may be set higher or higher, taking into account, for example, the temperature at which the internal resistance may become excessively high due to solidification of the electrolyte or ionic liquid in the power supply (or the temperature at which this becomes significant). The temperature T2b may be, for example, -10°C. The second temperature range determined by the upper limit temperature T2a and the lower limit temperature T2b is a range in which the structure and / or composition of the electrodes or electrolyte in the power supply do not change and the electrolyte or ionic liquid in the power supply does not solidify, thereby improving the safety and lifespan of the power supply with respect to discharge.

[0081] The third temperature range is a temperature range for which charging of the power source is permitted, and has an upper limit temperature T3a and a lower limit temperature T3b. As with the above ranges, the specific values ​​of the upper limit temperature and the lower limit temperature can be set appropriately.

[0082] The upper limit temperature T3a is not limited to, but may be set based on the same criteria as the upper limit temperature T2a of the first temperature range. As an example, the upper limit temperature T3a is 60°C. As another example, the upper limit temperature T3a may be different from the upper limit temperature T1a. For example, if the power source is a lithium-ion secondary battery, application of voltage at low temperatures may result in the deposition of metallic lithium on the surface of the negative electrode. Taking into account the temperature at which this so-called electrodeposition phenomenon may occur (or the temperature at which it becomes prominent), the lower limit temperature T3b may be set higher or equal to or higher than that temperature. The lower limit temperature T3b is, for example, 0°C. The third temperature range determined by the upper limit temperature T3a and the lower limit temperature T3b is within a range in which the structure and / or composition of the electrodes and electrolyte of the power source do not change and electrodeposition does not occur, thereby improving the safety and lifespan of the power source during charging.

[0083] The fourth temperature range is a temperature range for which rapid charging is permitted, and has an upper limit temperature T4a and a lower limit temperature T4b. As with the above ranges, the specific numerical values ​​of the upper limit temperature and the lower limit temperature can be set as appropriate. In this specification, rapid charging refers to charging performed at a higher rate than charging permitted in the third temperature range. As an example, rapid charging may be performed at a rate more than twice the normal charging rate. As an example, the rapid charging rate may be 2C and the normal charging rate may be 1C.

[0084] The upper limit temperature T4a is not limited to, but may be set based on the same criteria as the upper limit temperature T1a of the first temperature range. As an example, the upper limit temperature T4a is 60°C. As another example, the upper limit temperature T4a may be different from the upper limit temperature T1a. The lower limit temperature T4b may be set higher or higher, taking into account, for example, the temperature at which deterioration of the power supply is accelerated as a result of high-rate charging. The temperature T4b is, for example, 10°C. The fourth temperature range determined by the upper limit temperature T4a and the lower limit temperature T4b is a range in which the structure and / or composition of the electrodes and electrolyte of the power supply do not change and deterioration of the power supply is not accelerated, thereby improving the safety and lifespan of the power supply during rapid charging.

[0085] The first to fourth temperature ranges have been described above, but the relationship between each of the temperature ranges may be as follows: (1) With respect to the first temperature range, its lower limit temperature T1b may be set higher than the lower limit temperature T2b of the second temperature range. The lower limit temperature T1b may also be set higher than the lower limit temperatures T2b to T4b of all of the second to fourth temperature ranges. The upper limit temperature T1a may be set to be the same as or substantially the same as the upper limit temperatures T2a to T4a of the other temperature ranges (meaning that the range is within a numerical range obtained by increasing or decreasing the value of the comparison target by 10%; the same applies throughout this specification). Alternatively, the upper limit temperature T1a may be equal to or higher than the upper limit temperature T2a of the second temperature range, or the upper limit temperature T3a of the third temperature range, or the upper limit temperature T4a of the fourth temperature range. (2) With regard to the second temperature range, the second temperature range may be set to be wider than the first temperature range and to encompass the first temperature range (in this specification, "encompassing" includes cases where the upper limit temperatures are the same or the lower limit temperatures are the same; the same applies throughout this specification). In one aspect of the present invention, the second temperature range may be set to be wider than the temperature ranges in which other functions are permitted (in the example of FIG. 12, the first, third, and fourth temperature ranges). (3) Regarding the third temperature range, the third temperature range may be set to be wider than the first temperature range and to include the first temperature range. Also, the third temperature range may be set to be wider than the fourth temperature range and to include the fourth temperature range. (4) Regarding the fourth temperature range, the fourth temperature range may be set to be wider than the first temperature range and to include the first temperature range. In one aspect of the present invention, the first temperature range may be set to be narrower than the temperature ranges in which other functions are permitted (the second to fourth temperature ranges in the example of FIG. 12).

[0086] Incidentally, SOH diagnosis is generally performed based on electrical parameters of a power supply during discharging and charging. Examples of electrical parameters include the current value discharged or the voltage value output from the power supply during discharging, and the current value charged to the power supply during charging or the voltage value applied to the power supply during charging. If the first temperature range is set as described above, the power supply temperature within the first temperature range will necessarily fall within the second to fourth temperature ranges. Therefore, when SOH diagnosis is permitted, at least one of discharging, charging, and rapid charging is permitted simultaneously. Therefore, since the electrical parameters required for SOH diagnosis can be obtained by discharging, charging, or rapid charging, SOH diagnosis can be performed without any problems when SOH diagnosis is permitted. This improves the effectiveness of SOH diagnosis.

[0087] Furthermore, the electrical parameters used in the SOH diagnosis are affected not only by the deterioration of the power supply but also by the power supply temperature. Therefore, in order to ensure the accuracy of the SOH diagnosis, it is preferable to perform the SOH diagnosis only when the power supply temperature falls within a temperature range in which the effect on the electrical parameters used in the SOH diagnosis is small.

[0088] As a result of extensive research, the inventors of this application have found that the temperature range suitable for SOH diagnosis is narrower than the temperature range in which the power supply can be charged and discharged without accelerating degradation. They also found that, particularly at low temperatures, the influence of the power supply temperature on the electrical parameters used in SOH diagnosis becomes dominant.

[0089] If the first temperature range is set as described above, the power supply temperatures belonging to the second to fourth temperature ranges do not necessarily belong to the first temperature range. In other words, there are temperature ranges in which charging and discharging are permitted but SOH diagnosis is not permitted. By setting each temperature range in this manner, SOH diagnosis can be performed only in the appropriate temperature range, thereby improving the accuracy of SOH diagnosis. In particular, in a temperature range below 15°C, charging and discharging of the power supply are permitted from the perspective of suppressing deterioration of the power supply, but SOH diagnosis is not permitted from the perspective of ensuring the accuracy of SOH diagnosis, which is a preferred embodiment of the present invention.

[0090] Furthermore, discharging generally has a smaller impact on power supply degradation than charging. This difference in the impact of charging and discharging on power supply degradation becomes more pronounced as the power supply temperature decreases. By setting the second temperature range as described above, it is possible to maximize the opportunities for charging and discharging while suppressing power supply degradation.

[0091] Furthermore, charging generally has a smaller impact on power supply degradation than fast charging. This difference in the impact of charging and fast charging on power supply degradation becomes more pronounced as the power supply temperature drops. By setting the third temperature range and / or the fourth temperature range as described above, it is possible to maximize opportunities for charging and fast charging while suppressing power supply degradation.

[0092] In this way, by appropriately setting the first temperature range, the accuracy of the SOH diagnosis is improved, and the power supply 10 can be used for a longer period while ensuring safety, resulting in an energy saving effect.

[0093] Furthermore, by setting each temperature range appropriately, deterioration of the power supply 10 is suppressed, thereby extending the life of the power supply 10 and providing an energy-saving effect.

[0094] (a4) Deterioration diagnosis function 13 is a flowchart showing an example of a deterioration diagnosis or a failure diagnosis. In step S201, first, a power supply voltage value V batt The power supply voltage V batt can be obtained by a voltage sensor. Note that this flowchart is executed when the control circuit 50 (see FIG. 3) detects the start of suction.

[0095] Power supply voltage V batt For example, the power supply voltage value V may be an open circuit voltage (OCV) obtained without electrically connecting the power supply 10 and the load 125. batt For example, the power supply voltage value V may be a closed circuit voltage (CCV) obtained by electrically connecting the power supply 10 and the load 125. batt For example, the open circuit voltage (OCV) may be both the open circuit voltage and the closed circuit voltage. In order to eliminate the effects of voltage drop due to electrical connection of the load 10 and changes in internal resistance and temperature due to discharge, it may be preferable to use the open circuit voltage (OCV) rather than the closed circuit voltage (CCV). The open circuit voltage (OCV) may be estimated from the closed circuit voltage (CCV).

[0096] Power supply voltage V battSpecifically, the timing of acquisition may be during discharge while power is being supplied to the load, immediately before discharge, or immediately after discharge. "Immediately before discharge" may be, for example, the period before discharge starts, for example, from 5 to 10 msec until the discharge starts. "Immediately after discharge" may be, for example, the period from the end of discharge until 5 to 10 msec has elapsed.

[0097] In the flow of Figure 13, the power supply voltage value V batt However, the power supply voltage value V batt If it is necessary to obtain the power supply voltage value V immediately before or after charging, in addition to during charging, as described above, batt "Immediately before charging" may be, for example, the time from 5 to 10 msec before charging starts until the time charging starts. "Immediately after charging" may be, for example, the time from 5 to 10 msec after charging ends.

[0098] Next, in step S202, the acquired power supply voltage value V batt It is determined whether the voltage is equal to or less than the upper limit of a predetermined voltage range. If the voltage is higher than the upper limit, the process ends without estimating or detecting deterioration or failure of the power supply. As another example, if the voltage is higher than the upper limit, the process may return to step S201.

[0099] On the other hand, the power supply voltage value V batt If V is equal to or less than the predetermined upper limit, then in step S203, it is determined whether the power supply voltage value acquired during the previous suction operation was equal to or less than the upper limit of the predetermined voltage range. before If the value is higher than the upper limit of the predetermined voltage range, it is determined that the power supply voltage value has become equal to or lower than the upper limit of the predetermined voltage range for the first time due to the most recent suction operation. Next, in step S204, an accumulation counter (I Cо ) is set to "0." If the result of step S203 is No, it means that the power supply has been charged between the previous suction operation and the current suction operation.

[0100] If the result of step S203 is Yes, or after resetting the cumulative counter in step S204, then in step S205, the power supply voltage value V batt It is determined whether the power supply voltage value V is less than the lower limit of a predetermined voltage range. batt If is equal to or greater than the lower limit, in step S206, an integrated value of values ​​related to the amount of movement of the load, "ICo = ICo + Co", is derived. Co is a value related to the amount of movement of the load in the current suction operation. ICo is the cumulative value of values ​​related to the amount of movement of the load. Thereafter, the process ends without estimating or detecting deterioration or failure of the power supply.

[0101] In step S205, the power supply voltage V batt is less than the lower limit of the predetermined voltage range, then in S207, the power supply voltage value V batt The power supply is determined to be normal and the diagnostic function is terminated.

[0102] If the integrated value of IC is equal to or less than a predetermined threshold, it is determined that the power supply 10 has deteriorated or broken down (step S208), and the user is notified of the abnormality via the light-emitting unit 40 (step S209). If it is determined that the power supply has deteriorated or broken down, control may be performed to disable the power supply to the load 125, as necessary.

[0103] The degradation diagnosis function is not limited to the above-described embodiment, and various known methods can be employed. As one example, degradation of the power supply 10 may be determined if the power supply voltage drops significantly when the power supply 10 is discharged at a constant current or constant power. As another example, degradation of the power supply 10 may be determined if the power supply voltage rises quickly when the power supply 10 is charged. As another example, a failure of the power supply 10 may be determined if the power supply voltage drops when the power supply 10 is charged. As another example, degradation of the power supply 10 may be determined if the temperature rise rate of the power supply 10 is fast when the power supply 10 is charged or discharged. As another example, degradation of the power supply 10 may be determined if any of the integrated charge amount, integrated charge time, integrated discharge amount, and integrated discharge time of the power supply 10 exceeds a threshold value.

[0104] (a5) An example of operation control based on power supply temperature Next, an example of the operation of the aspirated component generating device 100 of this embodiment will be described with reference to the flowchart of Fig. 14. This flowchart shows the operation of the aspirated component generating device 100 when the power supply temperature T batt This shows an example of operation control based on the above.

[0105] First, in step S301, the suction component generation device 100 determines whether a suction operation is detected or whether the switch 30 (see FIG. 1) is ON. The detection of a suction operation may be based on the output of the suction sensor 20, as described above.

[0106] If the result of step S301 is No, steps S311 and thereafter are performed, which will be described later. On the other hand, if the result of step S301 is Yes, a request for aerosol generation by the user is detected. Next, in step S302, the power supply temperature T batt Calculate the power supply temperature T battAs described above, the calculation of may be performed by detecting the temperature of the power supply 10 with a temperature sensor and determining the power supply temperature based on the output, or by estimating the power supply temperature based on a value related to the power supply temperature, or by detecting the temperature of an object other than the power supply with a temperature sensor and estimating the power supply temperature based on the output. In any case, it is sufficient to be able to obtain or estimate the current power supply temperature, and the calculation is not limited to a specific means.

[0107] After step S302, the aspirated component generating device 100 performs step S303 to adjust the power supply temperature T batt As an example, if the power supply temperature is -10°C, the power supply temperature is determined to be within the second temperature range. <T batt Determine whether it is within the range of ≦60°C.

[0108] T batt If is not within this range (the result of step S302 is No), the sequence for when the temperature is abnormal (steps S381 and S382) is executed, which will be described later.

[0109] On the other hand, T batt If is within this range (if the result of step S302 is Yes), the inhaled component generation device 100 then generates an aerosol in step S304. The aerosol is generated by supplying power to the load 125. The control of the power supply is not limited to a specific control, and various control methods including the above-mentioned method and conventionally known methods can be used.

[0110] Next, in step S305, the aspirated component generating device 100 batt As an example, if the power supply temperature is 15°C, the <T batt Determine whether it is within the range of ≦60°C.

[0111] Power supply temperature T battIf the temperature is within the above temperature range (if the result of step S305 is Yes), the aspirated component generation device 100 performs SOH diagnosis, etc. in steps S306 and S307. Specifically, SOH diagnosis is performed in step S306, and it is determined in step S307 whether the SOH is equal to or greater than a predetermined threshold. Note that the deterioration diagnosis is not limited to a specific control, and various controls can be used, including the above-mentioned method and conventionally known methods.

[0112] If the SOH is equal to or greater than the predetermined threshold (if the result of step S307 is Yes), it is determined that the power supply 10 has not deteriorated, and steps S308 and S309, which will be described later, are then carried out.

[0113] On the other hand, if the SOH is less than the predetermined threshold (if the result of step S307 is No), the power supply 10 is determined to be degraded, and a sequence for when the battery is degraded (steps S391 to S394, see FIG. 16) is executed, which will be described later.

[0114] In step S305, the power supply temperature T batt If it is determined that the power supply voltage T is not within the above temperature range, steps S306 and S307 are skipped and the SOH diagnosis is not performed. batt The SOH diagnosis is performed only when the temperature is within the first temperature range. Although not limited thereto, if the temperature is not within this range, a predetermined notification (e.g., light emission from the light emitting unit 40) may be generated to notify the user that the diagnosis cannot be performed.

[0115] Referring again to FIG. 14, the inhaled component generating device 100 then determines in step S308 whether the suction operation has ended, whether the switch is OFF, or whether a predetermined time has elapsed. If the result of step S308 is No (i.e., the suction operation has not ended, the switch has not been turned OFF, or the predetermined time has not elapsed), the process returns to step S305. On the other hand, if the result of step S308 is Yes, the aerosol generation is completed in step S309. As another example, if the result of step S308 is No, the process may return to step S306 instead of step S305. This speeds up the flow, thereby increasing the number of SOH diagnoses.

[0116] Through the above-mentioned series of steps, the power supply temperature T batt The power supply to the load is only supplied when the power supply temperature T batt In this way, if SOH diagnosis is permitted only in a part of the temperature range in which discharge of power supply 10 is permitted, SOH diagnosis can be performed only in a temperature range in which the influence of power supply temperature is small, thereby improving the accuracy of the diagnosis.

[0117] (fast charging) Next, the steps from S311 onwards that are performed when the result of step S301 is No will be described. First, in step S311, the aspirated component production device 100 detects whether or not the charger is connected. If the connection of the charger is not detected, the process returns to step S301.

[0118] When the connection of the charger is detected, the inhaled component production device 100 detects the power supply temperature T batt Obtain or estimate the power supply temperature T batt The acquisition or estimation of can be performed in the same manner as in step S302.

[0119] Next, in step S313, the aspirated component generating device 100batt As an example, if the power supply temperature is 10°C, <T batt Determine whether it is within the range of ≦60°C.

[0120] Power supply temperature T batt If the difference is within this range (if the result of step S313 is Yes), the aspirated component production device 100 then performs rapid charging in step S314. Note that the charging rate in the CC mode of rapid charging may be 2C.

[0121] On the other hand, the power supply temperature T batt If is not within this range (the result of step S313 is No), the aspirated component production device 100 performs a normal charging sequence instead of a rapid charging sequence (step S321 and subsequent steps, details below).

[0122] When the rapid charging is started in step S314, the aspirated component production device 100 then, in step S315, batt is the first temperature range (e.g., 15°C <T batt ≦60℃).

[0123] Power supply temperature T batt If T is within this range (if the result of step S313 is Yes), the aspirated component generation device 100 performs SOH diagnosis etc. in steps S316 and S317. Specifically, SOH diagnosis is performed in step S316, and it is determined in step S317 whether the SOH is equal to or greater than a predetermined threshold. batt If is not within the first range, steps S316 and S317 are skipped and the SOH diagnosis is not performed.

[0124] If the SOH is equal to or greater than the predetermined threshold (if the result of step S317 is Yes), it is determined that the power supply 10 has not deteriorated, and steps S318 and S319, which will be described later, are then carried out.

[0125] On the other hand, if the SOH is less than the predetermined threshold (the result of step S317 is No), it is determined that the power supply 10 has deteriorated, and the sequence for when the battery is deteriorated (steps S391 to S394, see FIG. 16) is executed.

[0126] Next, in step S318, the aspirated component production device 100 detects the charging completion flag. If the result of step S318 is No (i.e., if charging is not complete), the process returns to step S315. If the result of step S318 is Yes, the charging is completed in step S319. As another example, if the result of step S318 is No, the process may return to step S316 instead of step S315. This speeds up the flow, and therefore the number of SOH diagnoses can be increased.

[0127] In this way, if SOH diagnosis is permitted only in a part of the temperature range in which rapid charging of power supply 10 is permitted, SOH diagnosis can be performed only in a temperature range in which the influence of power supply temperature is small, thereby improving the accuracy.

[0128] (normal charging) In step S313 described above, the power supply temperature T batt is the fourth temperature range (e.g. 10°C <T batt If it is determined that the temperature is not 0°C or lower (60°C or lower), the aspirated component generating device 100 performs the step S321. <T batt ≦10° C. (The combination of the contents of step S313 and the contents of step S321 determines whether the power supply temperature T is within the third temperature range.) batt If the power supply temperature T is not within this range (if the result of step S321 is No), the sequence for when the temperature is abnormal is executed (steps S381 and S382, details below). batt If is within this range (if the result of step S321 is Yes), the aspirated component production device 100 then performs normal charging in step S322. Note that the charging rate in the CC mode of normal charging may be 1C.

[0129] When normal charging is started in step S322, the aspirated component production device 100 then calculates the power supply temperature T batt is the first temperature range (e.g., 15°C <T batt ≦60℃).

[0130] Power supply temperature T batt If the power supply temperature T is within this range (if the result of step S323 is Yes), the aspirated component generation device 100 performs SOH diagnosis etc. in steps S324 and S325. Specifically, the SOH diagnosis is performed in step S324, and it is determined in step S325 whether the SOH is equal to or greater than a predetermined threshold value. batt If is not within the first range (the result of step S323 is No), steps S324 and S325 are skipped and the SOH diagnosis is not performed.

[0131] If the SOH is equal to or greater than the predetermined threshold (if the result of step S325 is Yes), it is determined that the power supply 10 has not deteriorated, and steps S326 and S327, which will be described later, are then carried out.

[0132] On the other hand, if the SOH is less than the predetermined threshold (the result of step S325 is No), it is determined that the power supply 10 has deteriorated, and the sequence for when the battery is deteriorated (steps S391 to S394, see FIG. 16) is executed.

[0133] Next, in step S326, the aspirated component production device 100 detects the charging completion flag. If the result of step S326 is No (i.e., if charging is not completed), the process returns to step S323. As another example, if the result of step S326 is No, the process may return to step S324 instead of step S323. This speeds up the flow, allowing the number of SOH diagnoses to be increased. If the result of step S326 is Yes, charging is completed in step S327.

[0134] In this way, if SOH diagnosis is permitted only in a part of the temperature range in which charging of power supply 10 is permitted, SOH diagnosis can be performed only in a temperature range that is less affected by the power supply temperature, thereby improving the accuracy.

[0135] (Sequence when temperature is abnormal) 15, the sequence for when a temperature abnormality occurs may be such that, first, the aspirated component production device 100 detects a temperature abnormality in step S381, and then stops charging or discharging in step S382. Note that the charging or discharging stopped in step S382 may be permitted again on the condition that a predetermined time has passed or the power supply temperature has returned to the normal range.

[0136] (Sequence when power supply deteriorates) A sequence for detecting battery deterioration may be, for example, as shown in Fig. 16. In this example, first, in step S391, the aspirated component production device 100 detects battery deterioration, and then, in step S392, stops charging or discharging.

[0137] Next, in step S393, the time when the deterioration of the power supply was detected and the conditions under which the deterioration was detected are stored in memory. Then, in step S394, the series of operations is stopped. Note that the series of operations stopped in step S394 may be permitted again under the condition that the power supply 10 is replaced, etc.

[0138] Comparing the sequence when there is an abnormal temperature with the sequence when the power supply has deteriorated, it can be said that the conditions for re-allowing charging or discharging that was stopped in step S382 are more difficult to meet than the conditions for re-allowing the series of operations that were stopped in step S394.

[0139] Comparing the sequence when the temperature is abnormal and the sequence when the power supply has deteriorated, the charging and discharging stopped in step S382 are permitted again if the aspirated component generator 100 is left alone. On the other hand, it can be said that the series of operations stopped in step S394 may be permitted again even if the aspirated component generator 100 is left alone.

[0140] In this way, by appropriately setting the first temperature range, the accuracy of the SOH diagnosis is improved, and the power supply 10 can be used for a longer period while ensuring safety, resulting in an energy saving effect.

[0141] Furthermore, by setting each temperature range appropriately, deterioration of the power supply 10 is suppressed, thereby extending the life of the power supply 10 and providing an energy-saving effect.

[0142] (b1) Detecting connection of chargers, etc. Various methods can be used for charging control and charger connection detection, and examples of these methods will be briefly described below. The charging control unit 250 (see FIG. 8) has a function of detecting that the electric circuit of the charger 200 and the electric circuit of the power supply unit 110 are electrically connected. There are no particular limitations on the method for detecting such an electrical connection, and various methods can be used, but for example, the connection of the power supply unit 110 may be detected by detecting the voltage difference between a pair of connection terminals 211t.

[0143] In one embodiment, it is preferable that the charger 200 is configured to be able to determine which type of power supply unit 110 and / or which type of power supply 10 has been connected when the charger 200 and the power supply unit 110 are connected. To achieve this, for example, the charger 200 may be configured to be able to determine the type of power supply unit 110 and / or the type of power supply 10 in the power supply unit 110 based on a value related to the electrical resistance of the first resistor 150 (see FIG. 8 ). That is, by changing the electrical resistance value of the first resistor 150 for each different type of power supply unit 110, it becomes possible to identify the connected power supply unit 110 or power supply 10. Note that the "value related to the electrical resistance value of the first resistor" may be the electrical resistance value of the first resistor 150 itself, the amount of voltage drop (potential difference) across the first resistor 150, or the value of the current passing through the first resistor 150.

[0144] (b2) Charging control Next, charging control will be described. Note that, although an example in which the charging control unit 250 of the charger 200 controls the operation will be shown below, as mentioned above, in a configuration in which the charging function is provided within the attraction component generation device 100, the main control unit may be the control circuit 50 on the device side. Fig. 17 is a flowchart showing an example of a control method by the charging control unit 250. First, in step S401, connection of the power supply unit 110 to the charger 200 is detected.

[0145] After the connection is detected (if the result of step S401 is Yes), next, in step S402, a value related to the electrical resistance of the first resistor 150 is acquired. In such a measurement, the value to be measured may be acquired multiple times, and the final value may be calculated based on these values ​​using a moving average, simple average, or weighted average.

[0146] Next, in step S403, it is determined whether the predetermined control needs to be changed or whether the predetermined control may be executed based on the value related to the electrical resistance value obtained above.

[0147] For example, if the electrical resistance value calculated above is outside a predetermined range or does not satisfy a predetermined condition, charging of the power supply 10 may not be performed. On the other hand, if the electrical resistance value calculated above is within a predetermined range or satisfies a predetermined condition, charging may be performed. In other words, the above-mentioned change in the predetermined control includes changing the charging process so that it is not performed. This prevents the occurrence of abnormalities by not sending charging current if the power supply unit is determined to be abnormal or to be a non-genuine power supply unit.

[0148] Furthermore, the change in the predetermined control may also be at least one of a change in the charging current value, a change in the charging rate, and a change in the charging time. As a specific example, it is preferable in one embodiment that the type of power supply unit 110 or power supply 10 is determined based on the value related to the electrical resistance calculated above, and the rate of the charging current is changed according to the determined type. This makes it possible to perform charging control with a high-rate charging current of 2 C or more for a power supply 10 that supports rapid charging, and to perform normal charging control with a low-rate charging current of 1 C or less for a power supply 10 that does not support rapid charging.

[0149] Next, in step S404, the power supply voltage value V batt Next, in step S405, the obtained power supply voltage value V batt is equal to or greater than a predetermined switching voltage. This switching voltage is a threshold value for dividing the constant current charging (CC charging) section from the constant voltage charging (CV charging) section, and although there are no particular limitations on the specific value, it may be in the range of 4.0V to 4.1V, for example.

[0150] Power supply voltage V batt If the voltage is less than the switching voltage (if the result of step S405 is No), constant current charging (CC charging) is performed (step S406). If the voltage is equal to or greater than the switching voltage (if the result of step S405 is Yes), constant voltage charging (CV charging) is performed (step S407). Note that in the constant voltage charging method, the power supply voltage increases as charging progresses, and the difference between the power supply voltage and the charging voltage decreases, so the charging current decreases.

[0151] If charging using the constant voltage charging method is started, in step S408, it is determined whether the charging current is equal to or less than a predetermined charging completion current. The charging current can be acquired by current sensor 230 in charger 200. If the charging current is greater than the predetermined charging completion current (if the result of step S408 is No), charging using the constant voltage charging method continues. If the charging current is equal to or less than the predetermined charging completion current (if the result of step S408 is Yes), it is determined that power source 10 is fully charged, and charging is stopped (step S409).

[0152] Naturally, the conditions for stopping charging may be other than the charging current, such as the time since the start of charging using a constant current charging method or a constant voltage charging method, the power supply voltage value, or the power supply temperature value.

[0153] Although the embodiments of the present invention have been described above with reference to the drawings, the present invention can be modified as appropriate within the scope of the gist thereof.

[0154] 14, it is assumed that processing is basically performed by a single control circuit, and in step S313 it is first determined whether rapid charging is possible (fourth temperature range), and if not, it is then determined in step S321 whether normal charging is possible (third temperature range). However, it may also be configured so that charger 200 determines whether the power supply temperature is within the fourth temperature range, and if the result is Yes, rapid charging is performed, and if the result is No, normal charging is performed.

[0155] (Low battery detection using closed circuit voltage) 18A shows a simplified diagram of the connection between the power supply 10 and the load 125. The power supply voltage value is measured by a voltage sensor 62 at both terminals of the power supply 10, for example, between the high potential side of the power supply 10 (equipotential to the node 156 in FIG. 6) and the ground (the potential of the contact 154 in FIG. 6 is approximately the ground potential), and the information is sent to the control circuit 50. The power supply from the power supply 10 to the load 125 is controlled by turning on and off a first switch 172.

[0156] When the first switch 172 is in the OFF state (switch OFF), no power is supplied to the load 125. The power supply voltage measured by the voltage sensor 62 at this time is called the open-circuit voltage OCV. When the first switch 172 is in the ON state (switch ON), power is supplied to the load 125. The power supply voltage measured by the voltage sensor 62 at this time is called the closed-circuit voltage CCV. In an ideal power supply, OCV and CCV are the same, but in an actual power supply such as a battery, the closed-circuit voltage CCV is smaller than the open-circuit voltage OCV due to internal resistance and capacitance. The closed-circuit voltage CCV is smaller than the open-circuit voltage OCV by the amount of losses due to internal resistance and capacitance.

[0157] 18B is a diagram showing an equivalent circuit model of a power supply. As shown in FIG. 18B, the power supply (battery) 10 is Batt (ideal power supply) and resistance value R imp and the internal resistance of R EDL The reactive resistance and capacitance value C EDL The open circuit voltage OCV of the power supply 10 can be considered as a model in which an RC parallel circuit consisting of an electric double layer capacitance of E is connected in series. Batt and the closed circuit voltage CCV (V meas ) can be expressed by the following equation (1).

[0158]

number

[0159] In equation (1), ΔE imp is the loss in the internal resistance (voltage drop), ΔE EDL indicates the loss (voltage drop) in the RC parallel circuit of FIG. 18B.

[0160] The current that the power supply 10 discharges is first C EDL Flowing towards C EDL As charging progresses, R EDL Based on this phenomenon, equation (1) can be rewritten as equation (2) below.

[0161]

number

[0162]

number

[0163] From equation (3), the current value I(0) discharged from power supply 10 immediately after switch 172 is turned on (t=0) can be expressed by the following equation (4).

[0164]

number

[0165] From equations (2) and (4), the closed circuit voltage V of the power source 10 immediately after the switch 172 is turned on (t=0) meas (0) can be expressed by the following equation (5).

[0166]

number

[0167] On the other hand, from equation (3), R EDL and C EDL Compared with the product of these, the value of the current discharged from power supply 10 when t becomes sufficiently large can be expressed by the following equation (6).

[0168]

number

[0169] From equation (2) and equation (6), R EDL and C EDL Compared to the product ofmeas (t) can be expressed by the following equation (7).

[0170]

number

[0171] In addition, R EDL and C EDL Since is a very small value, the current value at which the power supply 10 discharges and the closed circuit voltage V of the power supply 10 become equal at a relatively early stage after the switch 172 is turned ON. meas Note that (t) converges to the values ​​in equations (6) and (7), respectively.

[0172] As described above, the closed circuit voltage CCV (V meas ) is the open circuit voltage OCV(E Batt ) and the internal resistance R imp The voltage drop across the RC parallel circuit (which has a strong time dependency) is subtracted from the voltage drop across the RC parallel circuit (which has a strong time dependency). t is the current flow time, and R EDL C EDL is the time constant τ (also called the "relaxation time"). The change in the closed circuit voltage CCV over time is shown in the graph of FIG.

[0173] Next, FIG. 20 illustrates the relationship between suction detection and power supply control. As shown in FIG. 20, the suction component generator of this embodiment is configured, for example, to first detect the open-circuit voltage OCV at time t1 and then detect the closed-circuit voltage CCV at time t2. When detecting the closed-circuit voltage CCV, a pulse voltage is applied for voltage detection. The application time is preferably set to a time that does not generate aerosols or lead to overdischarge. Specifically, for example, the application time may be set to 5 msec or less, preferably 1 msec or less. The application time of the pulse voltage for voltage detection may be shorter than the minimum on-time allowed for PWM control performed after time t3.

[0174] Thereafter, at time t3, the duty ratio is set and power supply is started. Power supply may be ended at any timing, but in this example, power supply is ended when the end of suction is detected at time t4. Power supply may also be ended when a predetermined time has elapsed since power supply started. Power supply may also be ended when either the end of suction or the passage of a predetermined time is detected.

[0175] It should be noted that the open circuit voltage OCV and / or closed circuit voltage CCV may be measured multiple times rather than just once. In particular, the closed circuit voltage CCV is more susceptible to variability than the open circuit voltage OCV because it is affected by internal resistance and the electric double layer. Therefore, it is preferable to measure the closed circuit voltage CCV multiple times. It should be noted that since the open circuit voltage OCV also varies slightly in value, it may also be measured multiple times.

[0176] When both the open-circuit voltage OCV and the closed-circuit voltage CCV are measured multiple times, the number of measurements may be the same. Alternatively, the number of measurements of the closed-circuit voltage CCV may be greater. As a specific example, when the number of measurements of the closed-circuit voltage CCV is N (N is a natural number greater than or equal to 1) and the number of measurements of the open-circuit voltage OCV is M (M is a natural number greater than or equal to 1), the voltage measurements may be performed so that N>M. By performing voltage measurements in this manner, it is possible to obtain appropriate values ​​for the open-circuit voltage OCV and the closed-circuit voltage CCV in a short time while taking into account the magnitude of variation in each value.

[0177] Various methods can be used to obtain one voltage value (representative value) from multiple measured voltage values, and are not limited to a specific method. For example, the method may use the average value, median value, or mode value, or may involve making a predetermined correction to a certain value.

[0178] As another example, since a pulse voltage needs to be applied to a load, the closed-circuit voltage CCV may be measured only once. On the other hand, the open-circuit voltage OCV, which does not need to be applied with a pulse voltage, may be measured multiple times. Note that in this embodiment, the number of measurements of the closed-circuit voltage CCV is less than the number of measurements of the open-circuit voltage OCV.

[0179] The following aspects may be taken regarding the measurement of the voltage value: (i) Regarding the measurement of the closed circuit voltage, after the power supply 10 and the load 125 form a closed circuit state, the voltage value is measured after the relaxation time (time constant τ) has elapsed (see, for example, phase Ph1 in FIG. 19). As described above, immediately after the closed circuit state is formed, C EDL Flowing towards C EDL As charging progresses, R EDL The measured voltage value changes over time from the value of equation (5) to the value of equation (7). In other words, immediately after the closed-circuit state is formed, the measured voltage value gradually decreases from the value of equation (5) and converges to the value of equation (7). By measuring after the relaxation time has elapsed in this way, it is possible to obtain the closed-circuit voltage value in a stabilized state. To obtain a more accurate value, the measurement may be performed after 1.5τ, 2τ, or 3τ.

[0180] The relaxation time τ may be obtained from the data sheet of the power source 10, or may be obtained experimentally using the AC impedance method (Cole-Cole plot method) or the like.

[0181] Furthermore, (ii) when measuring the voltage value multiple times, it is also preferable to set the detection time longer than the relaxation time (time constant τ) (see, for example, phase Ph2 in Figure 19). By measuring for a time longer than the relaxation time (time constant τ), a stabilized voltage value after the relaxation time has elapsed is acquired, making it possible to obtain a closed-circuit voltage value based on the stabilized value. Note that (i) and (ii) may be performed independently or in combination.

[0182] (Load drive control according to remaining battery power) Next, the relationship between the remaining battery capacity and the drive control of the load will be explained with reference to FIGS. 21 and 22. FIG. 21 shows a curve illustrating the discharge characteristics of a secondary battery that can be used as a power source. The vertical axis represents the power supply voltage value, and the horizontal axis represents the usage time (which may also be considered as the charge rate). The power supply voltage value on the vertical axis may be either the open-circuit voltage (OCV) or the closed-circuit voltage (CCV). In particular, when the power supply voltage value on the vertical axis is the open-circuit voltage (OCV), the curve shown in FIG. 21 is also referred to as the state-of-charge-open-circuit voltage characteristic (SOC-OCV characteristic). The following explanation will use the SOC-OCV characteristic as an example. As such, for a secondary battery such as a lithium-ion battery, the curve includes an initial region (when the remaining capacity is high) in which the power supply voltage value drops relatively rapidly with use, a plateau region (when the remaining capacity is medium) in which the change in the power supply voltage value becomes more gradual, and a final region (when the remaining capacity is low) in which the power supply voltage value then drops relatively rapidly with use. In the example shown in FIG. 21, P1 is shown as the initial region, P2 as the plateau region, and P3 as the final region. Note that P2 is a point that has passed the middle of the plateau region and is approaching the end of it (that is, a state where the power supply voltage value is relatively low even in the same plateau region).

[0183] The plateau region refers to a region in which the change in power supply voltage value relative to a change in remaining capacity is small. The rate of change is not necessarily limited to a specific value because it depends on factors such as the battery composition. However, for example, the plateau region may be defined as a region in which the power supply voltage value is 0.01 to 0.005 (V / %) or less (e.g., a change in voltage value of 0.01 to 0.005 V when the state of charge (SOC) changes by 1%). Alternatively, the plateau region may be defined as a region of ±15 to 30% based on the point at which the change in power supply voltage value relative to a change in SOC is smallest. Alternatively, the plateau region may be defined as a region in which the change in power supply voltage value relative to a change in SOC is approximately constant.

[0184] In one embodiment of the load drive control described here, the closed circuit voltage CCV is measured and the voltage value or voltage waveform applied to the load is adjusted based on the measured closed circuit voltage CCV. For example, at least one of the pulse width, duty ratio, average value, effective value, voltage value, application time, or maximum application time of the voltage applied to the load can be adjusted.

[0185] We have already explained using Fig. 10 that when power is supplied from a power supply to a load by PWM control, the duty ratio is reduced (the pulse width is narrowed) when the power supply voltage value is relatively high, and the duty ratio is increased (the pulse width is widened) as the power supply voltage value decreases, and that when the power supply voltage becomes equal to or lower than (full charge voltage - Δ), power is supplied at a duty ratio of 100 (step S103 in Fig. 11). Furthermore, we have also explained using Fig. 9 how to control power supply to end depending on the cutoff time. Here, we will explain control that includes extending the cutoff time based on the power supply voltage (closed circuit voltage CCV).

[0186] FIG. 22(a) shows PWM control in the initial region. Here, a waveform with a duty ratio of less than 100 is set at the measured power supply voltage value V1. The maximum application time, which is the time during which the voltage application continues, is a predetermined time t max It is assumed that the maximum application time t max corresponds to the cutoff time explained using Figure 9. Under these conditions, the amount of power supplied to the load is expressed by the following equation (8.1), where D is the duty ratio and R is the resistance value of the load.

[0187]

number

[0188] Next, when the remaining battery charge drops and the battery voltage enters a plateau region, the duty cycle (pulse width) in PWM control is increased compared to the initial region. As the battery voltage drops, particularly near the end of the plateau region (low battery charge side), attempting to execute constant power control can result in a duty cycle of 100%. Figure 22(b) shows PWM control at point P2, i.e., near the end of the plateau region. In this example, an input waveform with a duty cycle of 100% is set at the measured power supply voltage value V2 (lower than V1). The amount of power supplied to the load is given by equation (8.2) above. In this embodiment, the input waveform may be set so that the amount of power in equation (8.2) is equal to or substantially equal to the amount of power in equation (8.1). In one embodiment of the present invention, one of the technical features is that the waveform supplied to the load is changed depending on the remaining battery charge. If the voltage is high throughout the entire plateau region, the duty ratio may be set to less than 100% throughout the entire plateau region, or the duty ratio may be set to less than 100% at the beginning of the plateau region and set to 100% at the end of the plateau region when the battery voltage has started to drop, or the duty ratio may be set to 100% throughout the entire plateau region.

[0189] Figure 22(c) shows PWM control in the final region (the region where the remaining charge has dropped further beyond the plateau region). In this example, the input waveform is set to a duty cycle of 100% at the measured power supply voltage value V3 (lower than V2). The amount of power supplied to the load is given by the above formula (8.3). In this control, the maximum application time t max The additional time α is added to and extended by the formula (8.3). The additional time α may be determined so that the amount of power applied in formula (8.3) is the same as or substantially the same as that in formula (8.1), formula (8.2), etc. That is, in this embodiment, when the remaining amount is low beyond the plateau region, the maximum application time is extended to drive the load, so that even when the remaining amount is low, it is possible to generate an aerosol (for example) in approximately the same way as in the plateau region.

[0190] In one embodiment, the amount of power supply voltage that must be lowered before the additional time α can be added can be determined based on the battery voltage value at which the duty ratio reaches 100% under PWM control. max The additional time α may be set to continue supplying power for a certain period of time, and to be added after the voltage drops to a point where the power shortage is no longer tolerable, for example, when the power drops to a voltage where a predetermined percentage (e.g., 90%, 80%, 70%, etc.) is reached. Alternatively, the additional time α may be set to be added when the end voltage of the plateau region (CCV is preferable, but OCV may be used instead) is reached.

[0191] The maximum application time after extension (t max +α), an upper limit time may be set. That is, the maximum application time t max may not be extended beyond a certain upper time limit.

[0192] (Example of acquiring open circuit voltage and closed circuit voltage and controlling a series of operations) 23 shows an example of a control flow of the aspirated component generating device. The aspirated component generating device of this embodiment may be configured to perform control such as the flow shown in the figure.

[0193] First, in step S501, the suction component production device 100 determines whether a suction operation has been detected or whether the switch 30 (see FIG. 1) has been turned on. The detection of a suction operation may be based on the output of the suction sensor 20, as described above. If the result of this step is No, step S501 is repeated; if the result is Yes, a timer is started in the following step S502.

[0194] After starting the timer, the aspirated component generation device 100 then acquires the open circuit voltage OCV in step S503. As described above, this step may be performed once or multiple times. As a specific example, based on one or more acquired values, an average value or the like may be calculated as needed to obtain one representative value of the power supply voltage.

[0195] Next, in step S504, it is determined whether the acquired open circuit voltage OCV exceeds a predetermined reference value. This predetermined reference value (referred to as a "second reference value" in the context of the claims) may be a reference value for determining whether or not to acquire the closed circuit voltage CCV described below. While not limited to a specific value, the second reference value may be, for example, 3.45 V. In one embodiment, the second reference value may be the end voltage of the plateau region when the remaining battery capacity is measured in terms of the open circuit voltage OCV. This second reference value for the open circuit voltage OCV may be set to be equal to or higher than the end-of-discharge voltage.

[0196] If the result of step S504 is Yes, then in step S505, the discharge FET is turned ON, and in step S506, the closed circuit voltage CCV is acquired. In this step, too, the voltage value may be acquired only once or may be acquired multiple times. The acquired values ​​may be used to calculate an average value, etc., as needed, to obtain one representative value of the power supply voltage value.

[0197] If the result of step S504 is No, a sequence for when the remaining charge is low is executed (step S521). This sequence may, for example, issue a charging alert. In this embodiment, if the result of step S504 is No (i.e., if the measured open circuit voltage value is equal to or less than the second reference value (e.g., 3.45 V)), the subsequent flow of obtaining the closed circuit voltage CCV is not performed, thereby suppressing unnecessary operation and discharge.

[0198] Next, in step S507, it is determined whether the acquired closed circuit voltage CCV exceeds a predetermined reference value (referred to as the "first reference value"). Although not limited to a specific numerical value, the first reference value may be, for example, 3.00 V, which is lower than the second reference value. As described above, the closed circuit voltage CCV is lower than the open circuit voltage OCV, so it is preferable that the first reference value be lower than the second reference value.

[0199] Figure 24 shows an example (e3, at room temperature) in which the closed-circuit voltage CCV exceeds a first reference value (e.g., 3.00 V). The figure also shows an example (e1, at room temperature) in which the open-circuit voltage OCV exceeds a second reference value (e.g., 3.45 V) and an example (e2) in which it is below the second reference value. As indicated by arrow α1 in e3, the closed-circuit voltage CCV is lower than the open-circuit voltage by the voltage drop (also known as IR drop) due to internal resistance and the electric double layer. e4 also takes low temperatures into account. At low temperatures, as indicated by arrow α2, internal resistance and reaction resistance increase, resulting in a further IR drop and a lower voltage value.

[0200] In one embodiment, the "first reference value" is preferably set to a value lower than the discharge end voltage (e.g., 3.2 V). The reason for this is to detect insufficient output from the power source 10 at low temperatures. Even if it is determined from the open circuit voltage OCV that the remaining charge of the power source 10 is sufficient, the output from the power source 10 may be insufficient due to the influence of temperature. As described above, the closed circuit voltage CCV reflects the internal resistance and the electric double layer value, which are strongly affected by temperature. Therefore, by using the closed circuit voltage CCV, it is possible to determine whether the output from the power source 10 is insufficient. If an attempt is made to determine whether the output from the power source 10 is insufficient without using the closed circuit voltage CCV, a temperature sensor for acquiring the temperature of the power source 10 would be required. Therefore, it is preferable to use the closed circuit voltage CCV from the standpoints of weight and cost.

[0201] In order to accurately detect a lack of output from the power supply 10 at low temperatures, in one embodiment, the first reference value (e.g., 3.0 V) is preferably equal to or lower than the possible closed-circuit voltage CCV when the temperature is lower than room temperature. It is even more preferable that the first reference value be a value that the closed-circuit voltage CCV cannot attain when the temperature of the power supply 10 is higher than room temperature and the voltage of the power supply 10 is equal to or higher than the discharge end voltage. In other words, the first reference value is preferably lower than the open-circuit voltage OCV of the power supply 10 in the discharge end state minus the voltage drop (IR drop) that occurs at room temperature in the internal resistance and the electric double layer. As described above, at low temperatures, the internal resistance and reaction resistance are worse than at room temperature, resulting in a further IR drop, which causes a voltage drop. Depending on the temperature of the power supply 10, this further IR drop at low temperatures can be relatively large, and the voltage may fall below 3.0 V even if the power supply 10 has a sufficient SOC. In other words, by setting the first reference value in this way, a threshold value is set that takes into consideration IR drop and the like at low temperatures, and it becomes possible to determine whether the output of the power supply 10 is good.

[0202] In this embodiment, prior to the PWM control described below, a determination is made as to whether the remaining charge of the power source 10 is insufficient based on the open circuit voltage OCV, and a determination is made as to whether the output of the power source 10 is insufficient based on the closed circuit voltage CCV. By obtaining multiple voltages with different characteristics from the power source 10 in this way, the state of the power source 10 can be grasped more accurately.

[0203] In this embodiment, after determining whether the remaining charge of the power source 10 is insufficient based on the open circuit voltage OCV (steps S503 and S504 in FIG. 23), it is then determined whether the output of the power source 10 is insufficient based on the closed circuit voltage CCV (steps S506 and S507). As a result, it is confirmed that the remaining charge of the power source 10 is not insufficient at the time the closed circuit voltage CCV is acquired, and it can be determined that the reason the closed circuit voltage CCV falls below the first reference value is because the output of the power source 10 is reduced when the temperature is low. Therefore, the state of the power source 10 can be determined more accurately than when only the closed circuit voltage CCV is used.

[0204] In this embodiment, the closed circuit voltage CCV is used not only to determine whether the remaining charge of the power supply 10 is insufficient, but also to set the duty ratio of PWM control and extend the maximum application time, which will be described later. Therefore, a single measurement of the closed circuit voltage CCV not only makes it possible to grasp the state of the power supply 10, but also to improve the accuracy of power supply control.

[0205] "Room temperature" may be defined as a range of, for example, 1°C to 30°C. In this case, "lower than room temperature" means less than 1°C. Although room temperature is used as the standard here, "normal temperature (for example, a range of 15°C to 25°C)" may also be used as the standard.

[0206] 23 again, if the result of step S507 is No, a sequence for low remaining charge is executed (step S521). This sequence may be, for example, a sequence that issues a charging alert, as described above. Note that in this embodiment, the sequence for low remaining charge is also executed when the output of power source 10 is insufficient, but instead, a sequence for low output that can be distinguished from the sequence for low remaining charge may be executed.

[0207] If the result of step S507 is Yes, then in step S508, it is determined whether the acquired closed-circuit voltage CCV further exceeds another predetermined reference value. This step is for determining whether the maximum application time needs to be extended (see also FIG. 22). As described above, the "predetermined reference value" may be set to the battery voltage value at which a duty ratio of 100% is reached under PWM control, the voltage at which a power shortage becomes unacceptable, or the voltage value indicating the end of the plateau region. If the closed-circuit voltage CCV exceeds the predetermined reference value (i.e., if the result of step S508 is Yes), in step S509, the maximum application time is not extended and PWM control based on the closed-circuit voltage CCV is performed.

[0208] On the other hand, if the closed circuit voltage CCV does not exceed the reference value (if the result of step S508 is No), that is, if the remaining power is below the predetermined reference, the maximum application time is extended in step S510 to supply power to the load. Note that, although not limited to, this time extension may be performed using the method shown in FIG. 22 above.

[0209] Next, after power supply starts, in step S511, it is determined whether the suction operation has ended, whether the switch has been turned off, or whether a predetermined time has elapsed. If the result of step S511 is No, power supply continues, and if Yes, the process proceeds to step S512, where aerosol generation is completed.

[0210] The above describes a specific example of the operation according to the flow of Figure 23, but it is not necessary to perform all of the steps in this flow, and it is of course possible to perform only a portion of them based on a different technical concept.

[0211] One technical idea of ​​the present invention is that a low remaining power state of the power supply is detected based on the closed circuit voltage CCV (steps S505 to S507, S521, etc.). Measurement of the open circuit voltage OCV may or may not be performed.

[0212] Another technical idea of ​​the present invention is characterized in that the closed circuit voltage CCV is measured and, based on the value, the application conditions for the load (adjustment of the voltage value and / or voltage waveform to be applied to the load) is performed (steps S508 to S510, etc.). In this case, too, measurement of the open circuit voltage OCV is not essential and may or may not be performed.

[0213] (Measurement of closed circuit voltage and determination of low remaining capacity based on the results) As described above, in one aspect of the present invention, the closed circuit voltage value is acquired, and it is possible to determine whether or not the remaining amount is low based on that value.

[0214] The aspirated component generator 100 of this embodiment may also include an auxiliary device that performs a predetermined operation when a low remaining charge is detected. Various auxiliary devices are available, including, for example, (i) a device that suppresses discharge of the power source 10, (ii) a device that notifies the user of a low remaining charge, and (iii) a device that adjusts the temperature of the power source. More specifically, the auxiliary device may function to suppress discharge of the power source 10 when a low remaining charge is detected. It is also preferable that the auxiliary device notify the user of a low remaining charge. It is also preferable that the auxiliary device heats the power source when a low remaining charge is detected. It is preferable to heat the power source 10 when it is determined that the power output of the power source 10 is insufficient based on the closed-circuit voltage CCV. Heating the power source 10 when it is in a low-temperature state reduces the voltage drop (IR drop) caused by the internal resistance of the power source 10, potentially resolving the power output insufficiency without charging the power source 10.

[0215] (Measurement of closed circuit voltage and adjustment of load application conditions based on the results) This embodiment also discloses that the voltage conditions applied to the load are appropriately adjusted based on the acquired closed-circuit voltage value. That is, as described with reference to FIGS. 21 and 22, in this type of aspirated component generation device 100, the measured power supply voltage value also varies depending on the current level of power consumption. Therefore, in one embodiment, it is preferable to adjust the voltage value and voltage waveform supplied to the load based on the power supply voltage value acquired by measurement (for example, V1, V2, V3, etc.; see FIG. 22).

[0216] However, continuing to supply power when the power supply 10's output is insufficient is undesirable because it accelerates deterioration of the power supply 10. According to this embodiment, the closed circuit voltage CCV is used to determine whether the power supply 10's output is insufficient, and if it is, the power supply 10's supply is at least temporarily suppressed. This suppresses deterioration of the power supply 10, which has the energy-saving effect of allowing the power supply 10 to be used for a longer period of time.

[0217] Furthermore, it is not preferable to charge and discharge the power supply 10 under appropriate conditions according to the remaining charge, etc., as this will accelerate deterioration of the power supply 10. According to this embodiment, the power supply control is performed using the accurate remaining charge of the power supply 10 as determined by the closed circuit voltage CCV, and therefore the accuracy of the power supply control is improved. Therefore, deterioration of the power supply 10 is suppressed, which has the energy-saving effect of allowing the power supply 10 to be used for a longer period of time.

[0218] Furthermore, according to one embodiment of the present invention, whether the power supply is in a low charge state is determined using the closed circuit voltage, which indicates the actual voltage value of the power supply 10, reflecting the temperature and deterioration state, thereby achieving an energy-saving effect of allowing the power supply 10 to be used for a longer period of time.
