Detailed Description

To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Embodiments of the present application are given in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or be connected to the other element through intervening elements. Further, "connection" in the following embodiments is understood to mean "electrical connection", "communication connection", or the like, if there is a transfer of electrical signals or data between the connected objects.

As used herein, the singular forms "a", "an" and "the" may include the plural forms as well, unless the context clearly indicates otherwise.

The battery charging process comprises four stages of trickle charging, constant-current charging, constant-voltage charging and charging termination, when the electric quantity of the charged battery is too low, a trickle charging mode is adopted, and the charging current in the trickle charging stage is relatively low so as to protect the battery. When the charged battery rises to be above the trickle charge threshold, constant-current charging is carried out, the constant-current charging stage is charged with fixed current, and the current ratio is large so as to realize quick charging. When the voltage of the battery to be charged rises above the constant current charging threshold, for example, 4.2V, a constant voltage charging mode is adopted, the charging circuit outputs a fixed voltage, and at this time, as the voltage of the battery to be charged gradually rises, the voltage difference between the output voltage of the charging circuit and the voltage of the battery to be charged gradually decreases, so that the charging current also gradually decreases, and the charging termination stage is entered to complete the charging cycle until the charging current is smaller than the minimum current threshold.

In split type atomizing device, by a battery to another battery charging process, the control circuit that charges needs obtain continuous voltage from the power supply battery, if the power supply battery electric quantity is not enough in the charging process, the output voltage of power supply battery is less than minimum allowable output voltage and can lead to the output to be interrupted the charging process, lead to by rechargeable battery can not accomplish a charging cycle, can not be full of the electricity, further can lead to the user to take place the outage condition at the use atomizing device in-process, user experience is poor.

In order to solve the technical problem in the background art, an aspect of the present application provides a charge control circuit, including: a charging circuit 20 and a controller 40. As shown in fig. 1, the input terminal of the charging circuit 20 is used for connecting the first battery 60, and the output terminal of the charging circuit 20 is used for connecting the second battery 80; the output terminal of the controller 40 is electrically connected to the control terminal of the charging circuit 20, and the controller 40 is configured to: acquiring residual capacity information of the first battery 60, wherein the residual capacity information is used for representing the residual capacity of the first battery 60; when it is determined from the remaining capacity information of the first battery 60 that the remaining capacity of the first battery 60 can cause the second battery 80 to complete at least one charging cycle, the charging circuit 20 is controlled to operate so that the first battery 60 charges the second battery 80.

The charging circuit 20 is a circuit capable of obtaining the electric energy of the first battery 60 and charging the second battery 80 with the input electric signal required for charging the second battery 80. The controller 40 refers to a device having information acquisition capability and control capability, and for example, the controller 40 may be an MCU (micro controller Unit), a single chip, a CPU, or the like. The controller 40 may acquire the remaining power information of the first battery 60 directly by connecting with the first battery 60, or may acquire the remaining power information indirectly by connecting with the first battery 60 through another device, and the controller 40 may also receive the remaining power information acquired by another sensor or another component such as a battery charge/discharge curve measuring device. The charging control circuit may be adapted for use in a charging control scenario for a split atomising device, which may be used for atomising a solid aerosol-like forming substrate. The first battery 60 and the second battery 80 may be lithium batteries. A charge cycle refers to the process of fully charging a fully discharged battery.

Specifically, in order to avoid the problem that the output of the first battery 60 is interrupted due to the insufficient electric quantity of the first battery 60 during the charging process, the second battery 80 cannot complete a charging cycle, cannot be fully charged, and cannot ensure the charging effect. Before charging, the controller 40 first obtains the remaining capacity information of the first battery 60, and determines whether the current remaining capacity of the first battery 60 is sufficient to support one charging cycle of the second battery 80 according to the remaining capacity information. If the determination result is yes, the controller 40 controls the charging circuit 20 to operate through a connection line with the charging circuit 20, so that the charging circuit 20 transmits the electric energy of the first battery 60 to the second battery 80.

In order to better explain the implementation process of the charging control circuit 1 provided in the embodiment of the present application, a scenario applied to a split type atomization device is exemplified herein. As shown in fig. 2, when applied to the separate type atomizer, the charge control circuit 1 is provided in a charging device 1000 of the separate type atomizer, and synchronously, a first battery 60 is also provided in the charging device 1000, and a second battery 80 configured to receive the charge of the first battery 60 is provided in an atomizer 2000 of the separate type atomizer, and the charging device 1000 and the atomizer 2000 are separable and united. When charging is required, the atomization device 2000 and the charging device 1000 are combined (as shown in fig. 2), and at this time, the charging circuit 20 and the second battery 80 are electrically connected, and the electrical connection may be a wireless coupling connection or a contact electrical connection. Before charging, the controller 40 in the charging control circuit 1 in fig. 1 obtains the remaining capacity information of the first battery 60, and if the controller 40 determines that the remaining capacity of the first battery 60 is sufficient to support one charging cycle of the second battery 80 according to the remaining capacity information, the controller 40 in the charging device 1000 controls the charging circuit 20 to operate through a connection line with the charging circuit 20, so that the charging circuit 20 transmits the electric energy of the first battery 60 to the second battery 80 in the atomizing device 2000, and it is ensured that the second battery 80 in the atomizing device 2000 can be fully charged, thereby further ensuring that the second battery 80 can meet the operating voltage requirement of the atomizing device 2000 for atomizing the aerosol-forming substrate.

From another perspective, the controller 40 controls the charging circuit 20 to operate to charge the first battery 60 to the second battery 80 when determining that the remaining capacity of the first battery 60 can enable the second battery 80 to complete at least one charging cycle according to the remaining capacity information of the first battery 60, that is, the controller 40 controls the charging circuit 20 to limit the first battery 60 from charging the second battery 80 when determining that the remaining capacity of the first battery 60 is not enough to enable the second battery 80 to complete at least one charging cycle according to the remaining capacity information of the first battery 60.

In one embodiment, the remaining capacity information of the first battery 60 includes an output voltage of the first battery 60, and the controller 40 is further configured to determine that the remaining capacity of the first battery 60 enables the second battery 80 to complete at least one charge cycle when the output voltage of the first battery 60 is not less than a threshold voltage; the threshold voltage is a voltage value that causes the second battery 80 to complete at least one charge cycle. The output voltage of the first battery 60 can be used to represent the remaining charge of the first battery 60, and the threshold voltage can be obtained according to the output voltage value corresponding to the remaining charge required by the second battery 80 in one charging cycle in the test process. When the output voltage of the first battery 60 is smaller than the threshold voltage, it indicates that the remaining capacity of the first battery 60 is not enough to support the second battery 80 to complete a charging cycle, that is, the output of the first battery 60 is interrupted due to insufficient capacity, and the second battery 80 may not be fully charged, so that a subsequent user may be interrupted during using the atomization device equipped with the second battery 80, which may affect the use effect. At this time, the controller 40 controls the charging circuit 20 not to start charging, i.e. the charging circuit 20 limits the first battery 60 from charging the second battery 80 under the control of the controller 40. Wherein the threshold voltage may be a voltage of 3.2V.

Only when the controller 40 determines that the remaining capacity is sufficient to support a charging cycle according to the output voltage of the first battery 60, that is, the output voltage of the first battery 60 is greater than or equal to the threshold voltage, the controller 40 controls the charging circuit 20 to start the charging operation, and the charging circuit 20 transmits the electric energy of the first battery 60 to the second battery 80 to supply power to the second battery 80, and the charging circuit 20 stops operating until the second battery 80 is fully charged. The charging control circuit provided by the embodiment of the application can ensure that at least one complete charging cycle can be rapidly completed in each charging, so that the second battery 80 can be rapidly charged fully, and the user experience is improved.

In one embodiment, as shown in FIG. 3, the first battery 60 is connected across two inputs of the controller 40, and the controller 40 is configured to collect an output voltage of the first battery 60. As shown in fig. 3, two input ends of the controller 40 are respectively connected to the positive electrode and the negative electrode of the first battery 60, so as to obtain voltages at two ends of the first battery 60, and the output voltage can be used to represent the remaining power of the battery, so that through the connection manner in fig. 3, the controller 40 can obtain voltage information capable of representing the remaining power of the first battery 60, and provide a data basis for subsequent charging start determination. It should be noted that, the remaining power information representing the remaining power of the battery is not limited to the output voltage of the first battery 60, and may also be the output current of the first battery 60, and the controller 40 may obtain the remaining power of the first battery 60 by collecting the output current of the first battery 60.

In one embodiment, the charge control circuit further includes: the first resistor R1 and the second resistor R2, the second resistor R2 is connected in series with the first resistor R1, the second resistor R2 is a bridge resistor between two input ends of the controller 40, and the controller 40 is configured to collect an output voltage of the first battery 60 (BAT 1).

As shown in fig. 3, the controller 40 may further be connected in series through a first resistor R1 and a second resistor R2 and then bridged across two ends of the first battery 60, and then a lead is led out from a connection of the first resistor R1 and the second resistor R2 to the controller 40 in a voltage division manner, the controller 40 may sample voltages at two ends of the second resistor R2 in the voltage division manner, and then an output voltage of the first battery 60 may be obtained according to resistance values of the second resistor R2 and the first resistor R1, and the output voltage of the first battery 60 is used as the battery remaining capacity information.

In one embodiment, as shown in fig. 4, the controller 40 is further configured to perform a prompt action for prompting charging of the first battery 60 (BAT 1) when the output voltage of the first battery 60 (BAT 1) is less than the threshold voltage. When the output voltage of the first battery 60 (BAT 1) is less than the threshold voltage, it indicates that the remaining capacity of the first battery 60 (BAT 1) is not enough to support the second battery 80 (BAT 2) to complete a charging cycle, at this time, the controller 40 may synchronously perform a prompt action to remind the user to charge the first battery 60, so that when the atomization device needs to be used, the first battery 60 (BAT 1) has enough remaining capacity to supply power to the second battery 80 (BAT 2), and the second battery 80 (BAT 2) is enabled to work in a full-power state to perform atomization processing. It should be noted that, the atomization device is used as an example here only to more clearly illustrate the operation implementation process and the beneficial effects of the charging control circuit provided in the embodiment of the present application, but the charging control circuit is not limited to be applied in the atomization device scenario, and may also be other devices.

In one embodiment, the controller 40 is configured to drive the LED lamp to light up and/or drive the display screen to display a prompt message and/or drive the vibration motor to operate and/or send a prompt message to the remote terminal when the remaining capacity of the first battery 60 is determined to be insufficient for the second battery 80 to complete at least one charging cycle according to the remaining capacity information of the first battery 60. In order to achieve a better prompting effect, in the charging circuit 20 provided in the embodiment of the present application, the controller 40 is further configured to control the LED lamp to operate when the remaining capacity of the first battery 60 is not enough to support a charging cycle of the second battery 80, so as to prompt the user to charge the first battery 60. Wherein the LED lamp may be arranged on the means for providing an operating voltage from the second battery 80, for example the LED lamp may be arranged on the nebulizing means for providing a nebulizing operating voltage for the aerosol-forming substrate from the second battery 80. In order to improve the prompting effect of the LED lamp, the LED and the like can be arranged on the shell of the atomization device in an embedded mode.

The prompt may be a prompt message displayed on the display screen by the controller 40, such as "the first battery 60 is low, needs to be charged" or the like, which can remind the user to charge the first battery 60, or "! "and the like with warning function. The display screen may be a screen embedded on the object powered by the second battery 80, for example, the display screen may refer to a screen on the atomizer powered by the second battery 80, and the screen may be embedded on the housing of the atomizer. The display screen may also be a screen of a remote terminal such as a mobile phone or a tablet, and the controller 40 is connected to the display screen through wired or wireless communication, and when it is determined that the remaining capacity of the first battery 60 is not enough to support a charging cycle of the second battery 80, sends a prompt message to the display screen, and drives the display screen to display the prompt message, so as to achieve the purpose of reminding a user of charging the first battery 60.

The vibration motor may be integrated on the second battery 80 powered object or on a terminal such as a user's cell phone. When it is determined that the remaining capacity of the first battery 60 is insufficient to support one charge cycle of the second battery 80, the controller 40 drives the vibration motor to operate through a wired or wireless connection with the vibration motor, and the user perceives the lack of the remaining capacity of the first battery 60 as a feeling of vibration and needs to be charged.

Now, mobile terminals such as mobile phones and tablets become an indispensable part of people's lives, users basically carry at least one mobile terminal device with them, and based on this, the controller 40 can send prompt information to the remote terminal and display it on the remote terminal when determining that the remaining capacity of the first battery 60 is not enough to support one charging cycle of the second battery 80.

To further enhance the prompting effect, when the output voltage of the first battery 60 is less than the threshold voltage, that is, it is determined that the remaining capacity of the first battery 60 is not enough to support one charging cycle of the second battery 80, the controller 40 may simultaneously perform several of the above prompting actions to prompt the user to charge the first battery 60.

In one embodiment, the controller 40 is configured to control the charging circuit 20 to charge the second battery 80 in a target charging mode according to the current voltage status of the second battery 80, wherein the target charging mode includes one or more of a trickle charging mode, a constant current charging mode, a constant voltage charging mode, and a charge termination mode. In order to optimize the charging performance of the second battery 80, the voltage stabilization tolerance is controlled within ± 1%. When the controller 40 controls the charging circuit 20 to operate, the current voltage state of the second battery 80 is further considered, and a different charging mode is selected according to the battery condition of the second battery 80, as described in the above embodiment, when the voltage of the second battery 80 is too low, it indicates that the remaining capacity of the second battery 80 is too low, and at this time, the charging is started from the trickle charging mode, and then the charging mode is changed successively according to the above embodiment until the charging current of the charging circuit 20 is smaller than the minimum current threshold, and the charging termination stage is entered to complete the charging cycle.

In one embodiment, the controller 40 is configured to control the charging circuit 20 to charge the second battery 80 in a trickle charge mode, a constant current charge mode, a constant voltage charge mode, and a charge termination mode during a charging cycle when the voltage of the second battery 80 is less than a first threshold before charging is started. The first threshold may be a threshold voltage characterizing the end of the trickle charge, for example, the first threshold may be a voltage value of 2V. If the voltage of the second battery 80 is less than the first threshold, which indicates that the remaining charge of the second battery 80 is currently too low, the charging circuit 20 is first in the trickle-charge mode to pre-charge the completely discharged second battery 80. Then, as described in the above embodiment, the charging circuit 20 sequentially operates in the constant current charging mode, the constant voltage charging mode, and the charging termination mode to charge the second battery 80 according to the magnitude of the output voltage during the charging of the second battery 80.

In one embodiment, the controller 40 is configured to control the charging circuit 20 to charge the second battery 80 in a constant current charging mode, a constant voltage charging mode, and a charge termination mode during a charging cycle when the voltage of the second battery 80 before the charging is turned on is greater than a first threshold and less than a second threshold.

The second threshold is a voltage corresponding to the end of the constant current charging stage in the charging process. For example, the second threshold may be a voltage value of 3.6V. Before the charging is started, if the voltage of the second battery 80 is greater than the first threshold, it is indicated that the voltage of the second battery 80 is not too low, and in order to perform the fast charging, when it is further determined that the voltage of the second battery 80 is less than the second threshold, it is indicated that the charged battery is suitable for the constant current charging mode, in the constant current mode, the charging circuit 20 may be controlled to perform the charging with the first current, the first current may be 3A, and the first current is not reduced in the whole constant current charging stage, so as to fast fully charge the second battery 80.

When the voltage of the second battery 80 before the start of charging is greater than the second threshold value and less than the third threshold value, the charging circuit 20 is controlled to charge the second battery 80 in the constant voltage charging mode and the charge termination mode during the charging cycle. The third threshold is a voltage corresponding to the end of the constant voltage charging phase. For example, the third threshold may be a voltage value of 3.65V. When the voltage of the second battery 80 is greater than 3.6V and less than 3.65V, the charging circuit 20 enters a constant voltage charging stage to charge the second battery 80 with a constant voltage until the voltage of the second battery 80 reaches 3.65V, the charging circuit 20 enters a charging termination mode, and the charging of the second battery 80 is completed.

Another aspect of the embodiments of the present application further provides a charging system, as shown in fig. 1 to 4, including: a first battery 60 configured to charge a second battery 80, the second battery 80, and the above-described charge control circuit.

The first battery 60 and the second battery 80 may be lithium batteries, among others.
