[0038] As can be seen from the above embodiments, the solution provided in this disclosure can acquire charging data of the electronic device during the charging process; then, based on the charging data, the charge pump module is controlled to switch to a target operating mode, where the target operating mode refers to the operating mode in which the charging loss power meets preset conditions under the charging data. Thus, in this embodiment, during the charging process, different operating modes can be switched according to the loss power. By switching the operating mode of the charge pump module, the charging loss of the electronic device, especially the loss function of the charge pump module, can be reduced, thereby improving the charging efficiency of the electronic device.

[0039] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0044] Figure 4 This is a block diagram illustrating a charging control device according to an exemplary embodiment.

[0045] Figure 5 This is a block diagram illustrating an electronic device according to an exemplary embodiment. Detailed Implementation

[0046] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described below by way of example do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatus consistent with some aspects of this disclosure as detailed in the appended claims. It should be noted that, without conflict, the following embodiments and features in the implementation methods can be combined with each other.

[0047] To address the aforementioned technical problems, this disclosure provides a charging control method applied to an electronic device, which includes a charge pump module and a battery. It is understood that this embodiment only shows components relevant to this disclosure, and other components required for the normal operation of the electronic device are not shown.

[0048] The aforementioned charge pump module refers to a charging module capable of performing voltage reduction, which may include a charge pump chip and a flying capacitor, etc. Furthermore, this charge pump module can support at least two voltage reduction ratio operating modes, such as at least two of 8:1, 4:1, 2:1, and 1:1. Considering that a higher voltage reduction ratio results in a larger output current and faster charging, the charge pump module typically switches in the order of 8:1, 4:1, 2:1 to 1:1, with the current at the switching moment being preset. It should be noted that the voltage reduction ratio of the charge pump module can be set according to specific scenarios. The following descriptions of various schemes using charge pump modules with four operating modes (8:1, 4:1, 2:1, and 1:1) do not constitute a limitation on this scheme.

[0049] In implementing this disclosed solution, the inventors discovered that the power loss of the input line and the power loss of the charge pump module are dynamic. Specifically, the lower the heat loss due to the resistance of the input line in the electronic device, the higher the heat loss of the charge pump module; conversely, the higher the heat loss due to the resistance of the input line, the lower the heat loss of the charge pump module. Therefore, by adjusting the switching time of the charge pump module's operating mode, the overall power loss of the electronic device can be kept at a low level, achieving the effect of reducing the power loss of the electronic device and improving charging efficiency. Simultaneously, switching operating modes can also adjust the heat distribution within the electronic device. For example, when switching to a lower reduction ratio operating mode, the heat loss of the charge pump module decreases while the heat loss of the input line increases, which can lower the temperature of the charge pump module. Due to the relatively dispersed nature of the input line, the heat distribution is also relatively dispersed, meaning it will not increase the temperature of the electronic device.

[0050] Therefore, this disclosure provides a charging control method. Figure 1 This is a flowchart illustrating a charging control method according to an exemplary embodiment, see [link to flowchart]. Figure 1A charging control method includes steps 11 and 12.

[0051] In step 11, the charging data of the electronic device is obtained.

[0052] In this embodiment, during the charging process, the electronic device can acquire charging data according to a set period or in real time, wherein the charging data may include the charging current of the electronic device. This charging current can be characterized by acquiring the output current of the charge pump module, or it can be derived by acquiring the voltage across a precision resistor (with a known resistance value) in the electronic device. The method for acquiring the current charging current of the battery can be selected according to the specific scenario, and the corresponding method falls within the protection scope of this disclosure.

[0053] In this embodiment, before acquiring the charging data of the electronic device, the electronic device can also determine the initial operating mode of the charge pump module, see [link to relevant documentation]. Figure 2 This includes steps 21 and 22:

[0054] In step 21, the electronic device can obtain the buck ratio corresponding to each working mode of the charge pump module. The buck ratio refers to the ratio of the input voltage to the output voltage of the charge pump module, such as 8:1, 4:1, 2:1 and 1:1.

[0055] In step 22, the electronic device can determine the operating mode with the largest step-down ratio as the initial operating mode of the charge pump module, such as an 8:1 step-down ratio. Then, the electronic device can control the charge pump module to switch to the initial operating mode. It is understood that the step-down ratio of subsequent candidate operating modes will be smaller than that of the initial operating mode. Alternatively, the electronic device can pre-store configuration data of the charge pump module, and determine the initial operating mode based on the configuration data each time charging occurs, thus achieving the solution of this disclosure.

[0056] In step 12, the charge pump module is controlled to switch to the target working mode according to the charging data. The target working mode refers to the working mode in which the charging loss power meets the preset conditions under the charging data.

[0057] In this embodiment, the electronic device can obtain the power loss of the charge pump module in the current operating mode and the candidate operating mode based on the charging current. The candidate operating mode refers to the operating mode in which the step-down ratio of the charge pump module is less than the step-down ratio of the current operating mode.

[0058] Taking the power loss of the charge pump module in the current operating mode of an electronic device as an example, the electronic device can also obtain the resistance of the input lines. For example, the resistance can be pre-detected and stored in the electronic device as a preset input line resistance. Alternatively, the input voltage and current of the charging interface, as well as the input voltage of the charge pump chip, can be obtained. The voltage difference between the input voltage of the charging interface and the input voltage of the charge pump chip is the voltage division of the input line resistance. Combining this with current and Ohm's law, the input line resistance can be calculated. The electronic device can calculate the power loss of the input lines based on the current charging current of the battery and the input line resistance, such as P1 = I... 2 R1.

[0059] The electronic device can also acquire the resistance of the charge pump module, which is a fixed value representing the on-resistance of multiple switching transistors. The number of switching transistors is related to the voltage reduction ratio of the charge pump module; for example, in 1:1 mode, there are three switching transistors. Furthermore, the resistance of the charge pump module can be pre-detected and stored in the electronic device. The electronic device can then directly read it from the storage location. The electronic device can calculate the power loss of the charge pump module based on the current charging current of the battery and the resistance of the charge pump module, such as P2 = I... 2 R2.

[0060] Understandably, the sum of the power loss of the input lines and the power loss of the charge pump module is the power loss of the electronic device in the current operating mode.

[0061] In another example, the electronic device can obtain the input voltage and current at its charging port, and based on these, it can determine the input power at the charging port. Then, the electronic device can calculate the battery's charging power based on the output voltage and current of the charge pump module, i.e., the battery's charging voltage and current. Thus, the difference between the input power at the charging port and the actual charging power represents the power loss of the electronic device in its current operating mode.

[0062] Similarly, when obtaining the charging current of the electronic device, the power loss in the candidate operating mode can be calculated based on the charging current, the resistance of the input line, and the resistance of the charge pump module. Since the buck ratio of the candidate operating mode is lower than that of the current operating mode, the input voltage at the charging interface will decrease and the input current will increase while the charging current remains constant. At this time, the electronic device can use the increased charging current to calculate the power loss of the input line and the power loss of the charge pump module. Then, by summing the power loss of the input line and the power loss of the charge pump module, the power loss of the electronic device can be obtained.

[0063] In yet another example, the electronic device can also obtain the charging current and charging efficiency to determine its power loss. For instance, in a 2:1 buck ratio operating mode, the power loss of the electronic device is P. total *(1-efficiency(div2)). Where div2 represents the 2:1 voltage reduction ratio operating mode; P total The charging power received at the charging interface of the electronic device is the product of the input current and input voltage at the charging interface. The charging efficiency of the electronic device when efficiency(div2) is 2:1 can be calculated from the input current and input voltage at the charging interface and the charging voltage and charging current of the battery.

[0064] In the 4:1 buck ratio operating mode, the power loss of the electronic device is P. total *(1-efficiency(div4)). Where div4 represents the 4:1 voltage reduction ratio operating mode; P total The charging power received at the charging interface of the electronic device is the product of the input current and input voltage at the charging interface. The charging efficiency of the electronic device when efficiency(div4) is 4:1 can be calculated from the input current and input voltage at the charging interface and the charging voltage and charging current of the battery.

[0065] In the 8:1 buck ratio operating mode, the power loss of the electronic device is P. total *(1-efficiency(div8)). Where div8 represents the 8:1 voltage reduction ratio operating mode; P total The charging power received at the charging interface of the electronic device is the product of the input current and input voltage at the charging interface. The charging efficiency of the electronic device when efficiency(div8) is 8:1 can be calculated from the input current and input voltage at the charging interface and the charging voltage and charging current of the battery.

[0066] It should be noted that the 1:1 step-down ratio operating mode can be obtained by calculating the sum of the power loss of the input line and the power loss of the charge pump. Since this scheme has already been described in the previous example, it will not be repeated here.

[0067] In this embodiment, after obtaining the first power loss in the current operating mode and the second power loss in the candidate operating mode, the first power loss and the second power loss can be compared. If the first power loss and the second power loss meet a preset condition, the electronic device can determine the candidate operating mode as the target operating mode, and at this time, the charge pump module can be controlled to switch to the target operating mode. The preset condition includes at least one of the following: the first power loss and the second power loss are equal, and the ratio of the second power loss to the first power loss is less than or equal to a preset ratio.

[0068] Taking the preset condition that the first and second power losses are equal as an example, the power losses in the current operating mode and the candidate operating mode are equal, meaning the electronic device can operate in either mode. Considering that the charging current typically decreases gradually during charging, and the power loss of the charge pump module decreases in the candidate operating mode, the power loss of the electronic device will decrease in subsequent charging processes. It is understandable that the input line losses will increase due to the increased charging current, but considering that the input lines are distributed, the resulting heat loss can be considered dispersed and will not create hot spots. If heat loss were concentrated in the charge pump module itself, it would create hot spots, thus preventing the thermal protection circuit from activating and improving charging efficiency.

[0069] Taking the preset condition that the ratio of the second power loss to the first power loss is less than or equal to a preset ratio as an example, the preset ratio can range from 0.8 to 0.95. That is, the switching occurs when the second power loss is less than the first power loss. This is because the charging current in the charging data is a fluctuating value. If the charging current fluctuates significantly at a certain moment, it will cause the charge pump module to switch back and forth in its working mode, thereby reducing charging efficiency.

[0070] In another embodiment, the electronic device may store a preset correspondence between switching currents and operating modes. See also Figure 3 In step 31, when the electronic device obtains the current charging current in the charging data, it can compare the current charging current with the corresponding switching current. In step 32, when the current charging current matches the corresponding switching current, the electronic device can determine the operating mode corresponding to the matching switching current as the target operating mode and control the charge pump module to switch to the target operating mode; otherwise, steps 31 and 32 are repeated.

[0071] The matching of the charging current and switching current means that the charging current and switching current are equal, or the charging current plus a compensation value is equal to the switching current. The compensation value can be +0.5A or -0.5A. Therefore, in this embodiment, the operating mode of the charge pump module can be switched using both the charging current and the switching current.

[0072] In this embodiment, the electronic device can also obtain the correspondence between the switching current and the operating mode, that is, obtain the switching current of the two operating modes. Taking the example that the power loss is equal in the current operating mode and the candidate operating mode, it includes:

[0073] Taking the switch from 2:1 to 1:1 as an example, the formula is:

[0074]

[0075] In the formula, div2 represents the 2:1 voltage reduction ratio operating mode; R chargepump-dir For the resistance of the charge pump module, taking a 2:1 ratio as an example, R chargepump-dir =2*R dson +R rb R dson To control the on-resistance of the transistor in the flyby capacitor of the charge pump module, R rb R is the on-resistance of the transistor in the charge pump module that prevents capacitor backflow; path P is the resistance of the input line between the charging interface and the input terminal of the charge pump module in the electronic device. total The charging power received at the charging interface of the electronic device is the product of the input current and input voltage at the charging interface; the charging efficiency (div2) of the electronic device when it is 2:1 can be calculated from the input current and input voltage at the charging interface and the charging voltage and charging current of the battery; I FCC This represents the switching current when switching from a 2:1 ratio to a 1:1 ratio.

[0076] It should be noted that the above formula applies to the scenario of switching from a 2:1 buck ratio to a 1:1 buck ratio. In the 2:1 buck ratio working mode, this example can first use this formula to calculate the charging current range that maximizes the benefits of the 2:1 mode, as well as the switching current when switching to the 1:1 mode, so as to achieve the effect of minimizing power consumption while distributing heat evenly (from concentrated to dispersed on the input line by the charge pump module).

[0077] In some examples, given a fixed charge pump module, the above formula can also be used to optimize the input circuitry to adjust its resistance, thereby reducing power loss in electronic devices.

[0078] For example, switching from a 4:1 to a 2:1 ratio would be represented by the following formula:

[0079]

[0080] In the formula, div4 represents the working mode with a 4:1 voltage reduction ratio.

[0081] It should be noted that the above formula applies to the scenario of switching from a 4:1 buck ratio to a 2:1 buck ratio. In the 4:1 buck ratio working mode, this example can first use this formula to calculate the charging current range that maximizes the benefits of the 4:1 mode, as well as the switching current when switching to the 2:1 mode, so as to achieve the effect of the lowest power consumption and uniform heat distribution.

[0082] For example, when switching from an 8:1 to a 4:1 ratio, the formula is:

[0083]

[0084] In the formula, div8 represents the working mode with an 8:1 voltage reduction ratio.

[0085] It should be noted that the above formula applies to the scenario of switching from an 8:1 buck ratio to a 4:1 buck ratio. In the 8:1 buck ratio working mode, this example can first use this formula to calculate the charging current range that maximizes the benefits of the 8:1 mode, as well as the switching current when switching to the 4:1 mode, so as to achieve the effect of the lowest power consumption and uniform heat distribution.

[0086] It should be noted that the scheme for obtaining the switching current only shows the case where the power loss is equal in the two operating modes. In some examples, a weight (such as 0.8 to 0.95) can be set for the power loss in the current operating mode, and the switching current can also be obtained. The corresponding scheme falls within the protection scope of this disclosure.

[0087] Thus, in the solution provided by this embodiment, charging data of the electronic device during charging can be acquired; then, the charge pump module is controlled to switch to a target operating mode based on the charging data. The target operating mode refers to the operating mode in which the charging power loss meets preset conditions under the charging data. In this way, by switching the operating mode of the charge pump module, the charging loss of the electronic device, especially the loss function of the charge pump module, can be reduced, thereby improving the charging efficiency of the electronic device.

[0088] Based on the charging control method provided in the embodiments of this disclosure, the embodiments of this disclosure also provide a charging control device, see [link to relevant documentation]. Figure 4 The device includes:

[0089] The charging data acquisition module 41 is used to acquire charging data of the electronic device, wherein the charge pump module of the electronic device supports at least two charging working modes.

[0090] The working mode switching module 42 is used to control the charge pump module to switch to a target working mode according to the charging data. The target working mode refers to the working mode in which the charging loss power meets the preset conditions under the charging data.

[0091] In one embodiment, the charging data includes at least the charging current; then the operating mode switching module includes:

[0092] The power loss acquisition unit is used to determine, based on the charging current, the first power loss of the electronic device in the current operating mode and the second power loss of the candidate operating mode, wherein the candidate operating mode is another operating mode among the at least two charging operating modes excluding the current operating mode.

[0093] A power loss comparison unit is used to compare the first power loss of the electronic device in the current operating mode with the second power loss of the candidate operating mode.

[0094] The working mode switching unit is used to determine the candidate working mode as the target working mode when the first power loss and the second power loss meet the preset conditions, and control the charge pump module to switch to the target working mode.

[0095] In one embodiment, the preset condition includes at least one of the following: the first power loss and the second power loss are equal, and the ratio of the second power loss to the first power loss is less than or equal to a preset ratio.

[0096] In one embodiment, the device further includes:

[0097] The step-down ratio acquisition module is used to acquire the step-down ratio corresponding to each working mode of the charge pump module. The step-down ratio refers to the ratio of the input voltage to the output voltage of the charge pump module.

[0098] An initial mode determination module is used to determine the operating mode with the largest voltage drop ratio as the initial operating mode of the charge pump module, and control the charge pump module to switch to the initial operating mode.

[0099] In one embodiment, the working mode switching module includes:

[0100] A current comparison unit is used to compare the current charging current in the charging data with the switching current in the corresponding relationship based on a preset correspondence between switching current and working mode.
