[0033] Please see Figure 1This is a charging control circuit 100 provided in an embodiment of this application. The charging control circuit 100 includes a battery unit 10, a removable battery cell 101, and a charging setting module 102. The charging setting module 102 stores safety charging parameters in advance and is configured to acquire the battery cell charging parameters of the removable battery cell 101. A charging management circuit 20 is connected to the battery unit 10 and is used to receive the power supply voltage of the charging power source. A controller 30 is connected to both the battery unit 10 and the charging management circuit 20. The controller 30 is configured to acquire the charging parameters stored in the charging setting module 102 and, based on the acquisition results, control the charging management circuit 20 to charge the removable battery cell 101 according to the battery cell charging parameters or the safety charging parameters.

[0034] Battery unit 10 is a portable battery, meaning that users can open the product's battery compartment and remove and replace the battery cells without needing special tools or training, based on common sense or product labeling instructions. For example, in the aerosol generating device, the removable battery cell 101 has various specifications for its charging cut-off voltage, such as 3.65V, 4.2V, 4.35V, 4.4V, and 4.45V, and its charging current also varies, supporting fast charging and not supporting fast charging.

[0035] The removable cell 101 is a rechargeable cell that can be powered by any suitable power source, such as a DC power source, or a battery. In one example, the battery is a lithium-ion battery, or it can be a nickel-metal hydride battery, a nickel-cadmium battery, or a lithium-based battery, such as a lithium cobalt, lithium iron phosphate, lithium titanate, or lithium polymer battery.

[0036] In some embodiments, safety charging parameters and cell charging parameters include charging current, charging voltage, charging temperature, etc.

[0037] In one example, the safe charging parameters are determined based on the lowest parameters of various types of batteries on the market and written into the charging setting module 102.

[0038] Please see Figure 2 or Figure 3 The battery unit 10 also includes a protection module 103, which is connected to the removable cell 101 and is used to protect the removable cell 101. In one specific embodiment, the protection module 103 and the charging setting module 102 are integrated on the battery protection board 11.

[0039] like Figure 4As shown, the charging setting module 102 includes a charging setting chip U1 and its peripheral circuits. The composition of its peripheral circuits and the connection relationship between the charging setting chip U1 and its peripheral circuits are shown in the figure, and will not be described again here. The protection module 103 includes a lithium protection chip U2, a switch Q1, and its peripheral circuits. The composition of its peripheral circuits and the connection relationship between the lithium protection chip U2, the switch Q1, and its peripheral circuits are shown in the figure, and will not be described again here. Terminal B+ is connected to the positive terminal of the removable battery cell 101, terminal B- is connected to the negative terminal of the removable battery cell 101, and terminals P+ and P- are used to output the driving voltage.

[0040] In some embodiments, the battery unit 10 further includes a filter circuit connected between the protection module 103 and the charging setting module 102. For example... Figure 4 As shown, the filter circuit includes capacitor C5.

[0041] Please continue reading. Figure 2 or Figure 3 The charging management circuit 20 includes a charging interface 201 and a charging chip 202 that are connected to each other. The charging interface 201 is used to receive the power supply voltage of the charging power supply. The charging chip 202 is also connected to the controller 30 and the removable battery cell 101. The charging chip 202 is configured to charge the removable battery cell 101 according to the battery cell charging parameters or safety charging parameters sent by the controller 30.

[0042] like Figure 5 As shown, the charging interface 201 includes a USB interface I NPUT, and the charging chip 202 includes a charging management chip U3. As an example, Figure 5 A peripheral circuit for a charging management chip U3 is also provided, the composition and connection relationship of which are shown in the figure.

[0043] In some embodiments, when replacing the removable battery cell 101, the replacement removable battery cell 101 is placed in the battery cell installation position. At this time, the removable battery cell 101 is connected to the charging setting module 102, and the charging setting module 102 obtains the battery cell charging parameters of the removable battery cell 101. The controller 30 detects the power-on action of the removable battery cell 101. When the power-on action of the removable battery cell 101 is detected, the controller 30 obtains the charging parameters stored in the charging setting module 102. In other embodiments, when replacing the removable battery cell 101, the replacement removable battery cell 101 is placed in the battery cell installation position, and the controller 30 detects the power-on action of the removable battery cell 101. When the power-on action of the removable battery cell 101 is detected, the controller 30 obtains the charging parameters through the charging setting module 102. Specifically, the controller 30 obtains the charging parameters through the charging setting module 102, including: the controller 30 obtains the battery cell charging parameters of the removable battery cell 101 through the charging setting module 102, or the controller 30 obtains the safety charging parameters stored in the charging setting module 102.

[0044] In one example, controller 30 may include a logic gate array, or a combination of a processor and memory storing a program executable in the processor.

[0045] Please continue reading. Figure 2 or Figure 3 The charging control circuit 100 also includes an input module 40 connected to the controller 30, which is also configured to receive charging parameters set by the input module 40.

[0046] In one example, input module 40 includes touchscreen 401.

[0047] In another example, the input module 40 includes a button 402; in this case, the charging control circuit 100 also includes a display module 50, connected to the controller 30, for displaying the charging parameters input by the button 402.

[0048] In one specific embodiment, the user presses and holds or rapidly and continuously triggers button 402 to enter the charging parameter setting mode. Then, the user enters the charging parameters as required in the product manual of the detachable battery cell 101 and checks the display module 50 to confirm whether the charging parameters have been set successfully.

[0049] In some cases, the battery cell 10 does not include the charging setting module 102, and the controller 30 cannot obtain the cell charging parameters of the removable cell 101. In this case, the user can select the input module 40 to set the charging parameters, thereby improving the applicability of the charging control circuit 100.

[0050] The charging control circuit provided in this application includes: a battery unit, comprising a removable battery cell and a charging setting module, wherein the charging setting module pre-stores safe charging parameters and is configured to acquire the cell charging parameters of the removable battery cell; a charging management circuit, connected to the battery unit, for receiving the power supply voltage of the charging power source; and a controller, connected to both the battery unit and the charging management circuit, configured to acquire the charging parameters stored in the charging setting module and, based on the acquisition results, control the charging management circuit to charge the removable battery cell according to the cell charging parameters or the safe charging parameters. Therefore, this application is compatible with third-party batteries while ensuring charging safety.

[0051] Please see Figure 6 This is a flowchart illustrating the charging control method provided in the embodiments of this application.

[0052] like Figure 6 As shown, the method includes:

[0053] Step S61: Replace the removable battery cell.

[0054] Step S62: When the detachable battery cell and the charging setting module are connected, the charging setting module obtains the battery cell charging parameters of the detachable battery cell.

[0055] Step S63: Does the controller detect that the detachable battery cell is powered on?

[0056] Step S64: When the controller detects that the detachable battery cell is powered on, the controller obtains the charging parameters stored in the charging setting module.

[0057] In some other embodiments, steps S62 to S64 can be replaced by: whether the controller detects that the removable battery cell is powered on; when the controller detects that the removable battery cell is powered on, the controller obtains the battery cell charging parameters of the removable battery cell through the charging setting module.

[0058] Based on the results obtained by the controller, execute any one of steps S651 to S653.

[0059] Step S651: If the controller obtains the cell charging parameters from the charging setting module, it controls the charging management circuit to charge the detachable cell according to the cell charging parameters.

[0060] Step S652: If the controller cannot obtain the cell charging parameters from the charging setting module, or if there is no feedback, the controller charging management circuit charges the detachable cell according to the safe charging parameters.

[0061] Step S653: If the controller cannot obtain the cell charging parameters from the charging setting module, or if there is no feedback, it receives the setting charging parameters sent by the input module and controls the charging management circuit to charge the detachable cell according to the setting charging parameters.

[0062] In some embodiments, the cell charging parameters correspond to the cell charging mode, and the safety charging parameters correspond to the safety charging mode. If the controller obtains the cell charging parameters from the charging setting module, it controls the charging control circuit to operate in the cell charging mode; if the controller does not obtain the cell charging parameters from the charging setting module, or obtains no feedback, it controls the charging control circuit to operate in the safety charging mode.

[0063] Therefore, when users replace the removable battery cells, they can charge the battery by reading the cell charging parameters of the removable battery cells, or they can charge the battery by using the safety charging parameters or the charging parameters set by the user if the cell charging parameters of the removable battery cells cannot be read. This ensures charging safety while being compatible with third-party batteries.

The aerosol generating apparatus 200 includes: a charging control circuit 100 as described in any embodiment of this application; a load 201 for heating an aerosol generating matrix to generate aerosol; and a switch 202 connected between the removable battery cell 101 and the load 201, and also connected to a controller 30, which is further configured to control the switch 202 to be turned on or off, thereby selecting or cutting off the current path between the removable battery cell 101 and the load 201.

[0065] In this embodiment, the load 201 includes: an atomizing component for heating the atomized liquid aerosol generating matrix; or a heating component for heating the atomized solid aerosol generating matrix.

[0066] In a further embodiment, the aerosol generating device 200 also includes a notification circuit 203 connected to the controller 30 for indicating the charging status of the removable battery cell 101.
