Description

Technical Field

[0001] This disclosure relates to the field of charging technology, and in particular to a charging control method, device, electronic device, storage medium, and program product. Background Technology

[0002] With the widespread adoption and diversification of electronic devices, chargers, as indispensable accessories, have seen increasing attention focused on their performance and power consumption. Current chargers typically use either Type-A or Type-C interfaces. While Type-A chargers are compatible with devices lacking a specific charging protocol, they cannot detect the connection status of such devices and therefore require the interface to remain constantly open, resulting in higher standby power consumption, which contradicts modern energy-saving principles. Type-C chargers, on the other hand, can enter a lower-power standby mode when no device is connected, but they only support devices with a specific charging protocol, limiting their usability and preventing them from charging devices without that protocol. This contradiction makes it difficult for users to balance efficient charging with energy conservation and emission reduction, especially in today's diverse device landscape and varying usage environments. Therefore, achieving both low-power standby and broad compatibility with all types of devices has become a pressing technical challenge. Summary of the Invention

[0056] In this embodiment, the electronic device acquires the electrical parameters at the charging interface of the charger in standby mode, and determines whether the charger is connected to a charging device based on the electrical parameters. Based on the determination result, the mode of the charger is maintained or switched. On the one hand, compared with the Type A interface charger in the related technology, which also generates a large power consumption (20mW) in standby mode without a charging device connected, this embodiment can achieve a standby mode with power consumption less than a preset power consumption threshold when the charger is not connected to a charging device, which can reduce unnecessary power consumption. Moreover, since the charger circuit is in a low power consumption state, it can also reduce the heat generation and wear of the components in the charger, thereby reducing the aging speed of the components and extending the service life of the charger. On the other hand, compared with the Type C interface charger in the related technology, which detects the connection status of the charging device based on the charging protocol and cannot detect the connection status of devices without the charging protocol, this embodiment can determine whether the charger is connected to a charging device based on the electrical parameters at the charger charging interface and determine whether to switch the current mode. The solution of this embodiment can identify any charging device, and the solution is simple, effective, and highly intelligent.

[0057] 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

[0058] The accompanying drawings, which are incorporated in and form a part of this specification, illustrate embodiments consistent with this disclosure and, together with the description, serve to explain the principles of this disclosure.

[0060] Figure 2 This is a flowchart illustrating a charging control method according to an exemplary embodiment.

[0061] Figure 3 This is a schematic diagram illustrating the power consumption of a charger in standby mode according to an exemplary embodiment.

[0062] Figure 4 This is a block diagram illustrating a charging control device according to an exemplary embodiment.

[0063] Figure 5 This is a structural block diagram of an electronic device according to an exemplary embodiment. Detailed Implementation

[0064] 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 in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0065] In related technologies, there is a type of charger with a Type A charging interface. Because this type of charger needs to accommodate many devices without charging protocols, such as wired mice, keyboards, printers, and electric fans, these devices usually do not require complex charging protocols and only need a simple 5V voltage to be charged. Therefore, in order to meet the charging needs of these devices, the output terminal of the Type A charger's charging interface is always at a high level. This can be understood as meaning that even if no device is connected to the charger, the charger's output terminal will still have a 5V voltage. Figure 1 This is the internal circuit diagram of the charger, in which... Figure 1 The dashed lines between circuit elements are a schematic representation of this part of the circuit, intended to show that these dashed sections also contain connections between circuit elements. L11 is a negative temperature coefficient thermistor, L12 is the circuit associated with the X-type safety capacitor, L13 is the power supply circuit associated with the power supply voltage, L14 is the circuit associated with the high-voltage capacitor, L15 is the circuit using pulse width modulation to control the switch, L16 is the protocol communication circuit and leakage circuit, and L17 is the rectifier switch circuit. Even when no charging device is connected, the above circuits will still generate power consumption while the output of the Type A interface charger remains at a high level. The total power consumption is approximately 20 milliwatts (mW). According to the standard protocol, the ideal power consumption of a charger in standby mode is less than 5 mW, which can be considered zero power consumption. 20 mW is far greater than 5 mW. Therefore, Type A interface chargers in related technologies will generate significant power consumption even in standby mode without a connected charging device.

[0066] Another type of charger in the related technology uses a Type-C charging interface. This type of charger only supports devices with a compatible charging protocol. When no compatible device is connected, it is in standby mode, keeping the output of the charging interface at a low level to reduce power consumption. Upon receiving a charging signal from a device with a compatible charging protocol, it enters charging mode, setting the output of the charging interface to a high level to charge the device. During charging, it communicates with the device based on the charging protocol and determines whether the device has disconnected from the charger. If it is determined that the device has disconnected, it enters standby mode and switches the output of the charging interface from high to low. Although this type of charger can set the output of the charging interface to a low level to reduce power consumption when no device is connected, it cannot detect the connection status of devices without a charging protocol, and therefore cannot charge devices without a charging protocol, such as wired mice, keyboards, printers, and electric fans.

[0067] In response, this disclosure provides a charging control method. Figure 2 This is a flowchart illustrating a charging control method according to an exemplary embodiment. Figure 2 As shown, the method mainly includes the following steps:

[0068] S21. When the charger is in standby mode, obtain the electrical parameters at the charging interface of the charger; wherein, the power consumption of the charger in standby mode is less than a preset power consumption threshold.

[0069] S22. Based on the electrical parameters, determine whether the charger is connected to a charging device;

[0070] S23. When the charging device is connected, switch from the standby mode to the charging mode to charge the charging device.

[0071] S24. When the charging device is not connected, maintain the charger in the standby mode.

[0072] In this embodiment of the disclosure, the charging control method can be applied to the charger itself, such as to the control unit inside the charger, and can also be applied to other electronic devices that can communicate with the charger, such as user equipment (UE), mobile devices, user terminals, mobile phones, tablets, personal digital assistants (PDAs), handheld devices, computing devices, in-vehicle devices, wearable devices, etc. For example, the electronic device can communicate with the charger based on Bluetooth or wireless network. This embodiment of the disclosure uses an electronic device as an example for illustration.

[0073] In step S21, the electronic device acquires the electrical parameters at the charging interface of the charger when the charger is in standby mode; wherein, the power consumption of the charger in standby mode is less than a preset power consumption threshold. In some embodiments, the charger is in standby mode when it is connected to a power source but not to a charging device; in other embodiments, the charger is in standby mode when it is connected to both a power source and a charging device, but is not supplying power to the charging device.

[0074] In this embodiment of the disclosure, the charging interface of the charger can be a Type A interface, a Type C interface, or a non-standard interface such as a circular interface. This embodiment of the disclosure does not impose any restrictions on this.

[0075] In this embodiment of the disclosure, the preset power consumption threshold is a set value, such as the ideal power consumption (5 milliwatts) of the charger in standby mode as specified in the standard protocol. Figure 3 This is a schematic diagram illustrating the power consumption of a charger in standby mode according to an exemplary embodiment, wherein L31 is the charger in this embodiment of the present disclosure, consisting of... Figure 3 It can be seen that the charger consumes 5 milliwatts when in standby mode.

[0076] It should be noted that in this embodiment, the charger is in a standby mode where the power consumption is less than a preset power consumption threshold. When the charger is in standby mode, the power consumption is less than that of a Type A interface charger in the related art when it is not connected to a charging device, and can be equivalent to the power consumption of a Type C interface charger in the related art when it is not connected to a charging device.

[0077] In this embodiment of the disclosure, the electronic device obtains the electrical parameters at the charging interface of the charger. It is understood that the charging interface of the charger typically includes multiple input / output pins, and the electronic device can obtain the electrical parameters of any input / output pin of the charging interface of the charger as the electrical parameters at the charging interface.

[0078] It should be noted that the internal circuit structure of the charger in this embodiment can be the same as the internal circuit of a charger in related technologies. The internal circuit of the charger can generate the electrical parameters at the charging interface of the charger. In this embodiment, a separate current source can also be set in the internal circuit of the charger to generate the electrical parameters of the charger in standby mode. In this embodiment, a separate current source can also be omitted, and the connection relationship of each component in the circuit can be changed to generate the electrical parameters of the charger in standby mode. This embodiment does not limit the scope of this embodiment.

[0079] In this embodiment of the disclosure, the electrical parameters at the charging interface can be the voltage at the charging interface, or other electrical parameters related to voltage, such as electric field strength. This embodiment of the disclosure does not limit the specific parameters.

[0080] In step S22, the electronic device determines whether the charger is connected to a charging device based on electrical parameters. In this embodiment, the charging device includes the aforementioned device without a charging protocol and / or a device with a charging protocol. As previously stated, the charger being in standby mode means either the charger is connected to a power source but not connected to a charging device, or the charger is connected to a power source and connected to a charging device, but is not supplying power to the charging device.

[0081] In some embodiments, the electronic device determines whether the charger is connected to a charging device based on electrical parameters. The electronic device also determines, based on electrical parameters, whether the charger, in a standby mode connected to power but not connected to a charging device, changes from being unconnected to being connected to a charging device. In other embodiments, the electronic device determines whether the charger is connected to a charging device based on electrical parameters. Furthermore, the electronic device, based on electrical parameters, determines whether the charger, in a standby mode connected to power and connected to a charging device but not supplying power to the charging device, changes the connected charging device. This disclosure uses the example of the charger being in a standby mode connected to power but not connected to a charging device, and determining, based on electrical parameters, whether the charger changes from being unconnected to being connected to a charging device.

[0082] In some embodiments, the electronic device can determine whether the charger is connected to a charging device based on changes in electrical parameters. For example, if the value of the electrical parameter obtained by the electronic device changes significantly, such as when the electrical parameter is voltage, if the voltage drops from 3.3V to less than 1V, it can be determined that the charger is connected to a charging device.

[0083] In other embodiments, the determination of whether the charger is connected to a charging device can also be based on the relationship between electrical parameters and preset electrical parameter thresholds. If the electrical parameter is voltage, determining whether the charger is connected to a charging device based on the electrical parameter includes:

[0084] In response to the voltage being greater than a first voltage threshold and less than or equal to a second voltage threshold, it is determined that the charger is not connected to the charging device;

[0085] In response to the voltage being less than or equal to the first voltage threshold, it is determined that the charger is connected to the charging device.

[0086] In this embodiment of the disclosure, the first voltage threshold can be a set value, such as one that can be measured experimentally. For example, the first voltage threshold can be 1V. The second voltage threshold can be the maximum voltage value that the charger can output at the charging interface in standby mode. For example, the second voltage threshold can be 3.3V.

[0087] It should be noted that the first voltage threshold is greater than 0V. Due to the performance issues of some charger cables, when a charging device is connected, the voltage may not drop from a higher voltage, such as 3.3V, to 0V, but may drop to a certain value greater than 0V, such as 0.8V. Therefore, setting the first voltage threshold to 1V can improve the accuracy of determining whether a charging device is connected to the charger.

[0088] In this embodiment of the disclosure, the electronic device determines that the charger is not connected to the charging device in response to a voltage greater than a first voltage threshold and less than or equal to a second voltage threshold. For example, when the first voltage threshold is 1V and the second voltage threshold is 3.3V, the electronic device determines that the charger is not connected to the charging device in response to a voltage at the charger charging interface that is greater than 1V and less than 3.3V.

[0089] In this embodiment of the disclosure, when the charger changes from being unconnected to being connected to a device, the voltage at the charger's charging interface will exhibit a certain capacitive impedance due to the connection of the charging device. The capacitive components (such as capacitors) inside the charging device will form a circuit with the components inside the charger. The capacitive impedance of the capacitive components in this circuit will impede the current and voltage in the circuit, thereby reducing the voltage at the charger's charging interface.

[0090] Therefore, in this embodiment of the present disclosure, the electronic device determines that the charger is connected to a charging device in response to a voltage less than or equal to a first voltage threshold. For example, when the first voltage threshold is 1V, the electronic device determines that the charger is connected to a charging device in response to a voltage less than or equal to 1V at the charger charging interface.

[0091] In this embodiment, on the one hand, since voltage changes are usually rapid, especially when the charger is connected to or disconnected from the device, the voltage will change immediately. Therefore, voltage judgment can improve the speed of determining whether the charger is connected to the charging device. On the other hand, compared with electrical parameters such as current and power, voltage is relatively stable and not easily affected by external interference. Voltage judgment can improve the accuracy of the judgment and reduce the possibility of misjudgment. Moreover, the relationship between voltage and threshold can be used to determine whether the charger is connected to the charging device. The solution is simple and effective.

[0092] In step S23, when a charging device is connected, the electronic device switches from standby mode to charging mode to charge the charging device. In this embodiment of the present disclosure, when the electronic device determines that a charging device is connected to the charger based on the electrical parameters at the charger's charging interface, it switches from standby mode to charging mode to charge the charging device. In charging mode, the charger adjusts its output voltage and current to charge the device, such as switching the output voltage to 5V.

[0093] In step S24, the electronic device maintains the charger in standby mode when no charging device is connected. In this embodiment of the present disclosure, the electronic device maintains the charger in standby mode when it is determined, based on the electrical parameters at the charger's charging interface, that the charger is not connected to a charging device.

[0094] In this embodiment, the electronic device acquires the electrical parameters at the charging interface of the charger in standby mode, and determines whether the charger is connected to a charging device based on the electrical parameters. Based on the determination result, the mode of the charger is maintained or switched. On the one hand, compared with the Type A interface charger in the related technology, which also generates a large power consumption (20mW) in standby mode without a charging device connected, this embodiment can achieve a standby mode with power consumption less than a preset power consumption threshold when the charger is not connected to a charging device, which can reduce unnecessary power consumption. Moreover, since the charger circuit is in a low power consumption state, it can also reduce the heat generation and wear of the components in the charger, thereby reducing the aging speed of the components and extending the service life of the charger. On the other hand, compared with the Type C interface charger in the related technology, which detects the connection status of the charging device based on the charging protocol and cannot detect the connection status of devices without the charging protocol, this embodiment can determine whether the charger is connected to a charging device based on the electrical parameters at the charger charging interface and determine whether to switch the current mode. The solution of this embodiment can identify any charging device, and the solution is simple, effective, and highly intelligent.

[0095] In some embodiments, the method further includes:

[0096] After switching the charger from the standby mode to the charging mode, it is determined whether there is a communication signal between the charger and the connected charging device; wherein, the communication signal is a signal associated with a preset charging protocol;

[0097] In response to the existence of a communication signal between the charger and the connected charging device, based on the changes in the communication signal, it is determined to maintain the charger in the charging mode or switch the charger from the charging mode to the standby mode;

[0098] In response to the absence of a communication signal between the charger and the connected charging device, based on the charging parameters of the charger charging the charging device, it is determined to maintain the charger in the charging mode or switch the charger from the charging mode to the standby mode.

[0099] In this embodiment of the disclosure, after the electronic device determines that the charger is connected to a charging device based on electrical parameters and switches the charger from standby mode to charging mode, it determines whether there is a communication signal between the charger and the connected charging device. The communication signal is a signal associated with a preset charging protocol, which may include Power Delivery (PD) protocol, Quick Charge (QC) protocol, Universal FastCharging Specification (UFCS) protocol, etc.

[0100] In this embodiment of the disclosure, a communication signal exists between the charger and the connected charging device to indicate that the charging device is the aforementioned protocol-compliant device. The charger and the charging device communicate based on a preset charging protocol, such as the communication rules, data format, and interaction process defined in the preset communication protocol between the charger and the charging device.

[0101] In this embodiment of the disclosure, the electronic device responds to the existence of a communication signal between the charger and the connected charging device, and determines, based on the changes in the communication signal, whether to maintain the charger in charging mode or to switch the charger from charging mode to standby mode.

[0102] In some embodiments, in response to the charging device connected to the charger being a protocol-connected device, the electronic device determines whether to maintain the charger in charging mode or switch the charger from charging mode to standby mode based on whether the type of communication signal changes. For example, the electronic device determines to maintain the charger in charging mode in response to the communication signal between the charger and the charging device being a communication signal associated with charging parameters, indicating that the charging process is in progress; and switches the charger from charging mode to standby mode in response to the communication signal between the charger and the charging device changing from a communication signal associated with charging parameters to a signal indicating that the charging device has completed charging.

[0103] In other embodiments, determining, based on changes in the communication signal, to maintain the charger in the charging mode or switch the charger from the charging mode to the standby mode includes:

[0104] In response to the communication signal being uninterrupted, or the duration of the interruption being less than a first preset duration threshold, it is determined to maintain the charger in the charging mode;

[0105] In response to the interruption of the communication signal, and the duration of the interruption is greater than the first preset duration threshold, the charger is switched from the charging mode to the standby mode.

[0106] In this embodiment of the disclosure, the electronic device, in response to the charging device connected to the charger being a device with a protocol, determines whether to maintain the charger in charging mode or switch the charger from charging mode to standby mode based on whether the communication signal is interrupted and the duration of the interruption.

[0107] In this embodiment of the disclosure, if the electronic device responds to the uninterrupted communication signal or the duration of the interruption is less than a first preset duration threshold, it indicates that the charging device is in the charging process, and it is determined to maintain the charger in the charging mode. The first preset duration is a set value, such as 1s, 3s, etc., and this embodiment of the disclosure does not limit it.

[0108] In this embodiment of the present disclosure, if the electronic device responds to the interruption of the communication signal and the duration of the interruption is greater than a first preset duration threshold, it indicates that the device has completed charging and the charger is switched from charging mode to standby mode.

[0109] In this embodiment of the disclosure, the electronic device determines whether to maintain the charger in charging mode or switch the charger from charging mode to standby mode based on whether the communication signal is interrupted and the duration of the interruption. On the one hand, maintaining the charger in charging mode when the communication signal is uninterrupted or the interruption duration is less than a first preset duration threshold means that the charger will not be mistakenly judged as having completed charging and switch modes due to a brief communication interruption, thus improving the accuracy of mode switching. On the other hand, switching to standby mode when the communication signal interruption duration is greater than the first preset duration threshold means that if the connection between the charging device and the charger is unstable for a long time or has been disconnected (for example, the user has unplugged the charging cable), the charger will switch to a standby mode with lower power consumption to reduce unnecessary energy waste.

[0110] In this embodiment of the disclosure, in response to the absence of a communication signal between the charger and the connected charging device, the electronic device determines whether to maintain the charger in charging mode or switch the charger from charging mode to standby mode based on the charging parameters of the charger charging the charging device. The charging parameters may be charging current, charging voltage, charging power, etc. It should be noted that the type of charging parameters is different from the type of electrical parameters at the aforementioned charging interface. For example, when the charging parameter is charging current, the electrical parameters at the aforementioned charging interface may be voltage.

[0111] In this embodiment of the disclosure, the electronic device can determine whether to maintain the charger in a charging mode or switch the charger from a charging mode to a standby mode based on the stable state of the charging parameters of the charger charging the charging device. The electronic device can also determine whether to maintain the charger in a charging mode or switch the charger from a charging mode to a standby mode based on the relationship between the charging parameters of the charger charging the charging device and a preset charging parameter threshold. The electronic device can also determine whether to maintain the charger in a charging mode or switch the charger from a charging mode to a standby mode based on the matching degree between the various charging parameters of the charger charging the charging device. For example, the charging parameters include charging temperature and charging power. The electronic device determines whether to maintain the charger in a charging mode or switch the charger from a charging mode to a standby mode based on the matching degree between the charging temperature and the charging power.

[0112] In this embodiment, when a communication signal exists between the charger and the charging device, changes in the communication signal can accurately determine whether the charging device is charging, thus enabling charger mode switching. However, when no communication signal exists, it is impossible to accurately determine whether the charging device is charging based on the communication signal. Therefore, charging parameters are needed to determine whether the charging device is charging, thus enabling charger mode switching. This embodiment offers high flexibility and is applicable to any charging device.

[0113] In some embodiments, the step of determining, based on charging parameters of the charger charging the charging device, to maintain the charger in the charging mode or switch the charger from the charging mode to the standby mode in response to the absence of a communication signal between the charger and the connected charging device includes:

[0114] In response to the absence of a communication signal between the charger and the connected charging device, and when the charging parameters meet preset conditions, based on the electrical parameters at the charger's charging interface, it is determined to maintain the charger in the charging mode or switch the charger from the charging mode to the standby mode.

[0115] In response to the absence of a communication signal between the charger and the connected charging device, and if the charging parameters do not meet the preset conditions, it is determined to maintain the charger in the charging mode.

[0116] In this embodiment of the disclosure, the electronic device, in response to the absence of a communication signal between the charger and the connected charging device, and provided that the charging parameters meet preset conditions, determines whether to maintain the charger in charging mode or switch the charger from charging mode to standby mode based on the electrical parameters at the charger's charging interface. In some embodiments, meeting the preset conditions for charging parameters can mean that the charging parameters are within a preset range. For example, if the charging parameter is the charging current, and the preset charging current range is 0.5A-5A, then when the charging current is within 0.5A-5A, such as 1A or 2A, it is considered that the charging parameters meet the preset conditions.

[0117] In other embodiments, the charging parameter meeting the preset condition can also be that the fluctuation of the charging parameter is within a preset fluctuation range. For example, if the charging parameter is the charging current and the preset fluctuation range is 0.5A, then the fluctuation of the charging current within 0.5A is considered as the charging parameter meeting the preset condition. The fluctuation of the charging parameter can be the fluctuation of the charging parameter relative to the preset charging parameter. For example, when the charging parameter is the charging current, the fluctuation of the charging current can be the fluctuation of the charging current relative to the rated current.

[0118] In this embodiment of the disclosure, when the charging parameters meet the preset conditions, the electronic device determines whether to maintain the charger in charging mode or switch the charger from charging mode to standby mode based on the electrical parameters at the charging interface of the charger. The electrical parameters at the charging interface can be the electrical parameters described above, such as voltage, electric field strength, etc. It should be noted that the types of charging parameters and electrical parameters at the charging interface are different. For example, when the charging parameter is the charging current, the electrical parameter at the charging interface can be the voltage.

[0119] In some embodiments, the electronic device may determine whether to maintain the charger in charging mode or switch the charger from charging mode to standby mode based on changes in electrical parameters. For example, if the value of the electrical parameter obtained by the electronic device changes significantly, such as when the electrical parameter is voltage, if the voltage changes from 1V to 3.3V, the charger may be switched from charging mode to standby mode.

[0120] In other embodiments, the electronic device may also determine whether to maintain the charger in charging mode or switch the charger from charging mode to standby mode based on the relationship between the electrical parameters and the preset electrical parameter threshold. For example, when the electrical parameters are greater than the preset electrical parameter threshold, it is determined to switch the charger from charging mode to standby mode, and when the electrical parameters are less than the preset electrical parameter threshold, it is determined to maintain the charger in charging mode.

[0121] In this embodiment of the disclosure, the electronic device determines to maintain the charger in charging mode in response to the absence of a communication signal between the charger and the connected charging device, and when the charging parameters do not meet the preset conditions.

[0122] In this embodiment, the electronic device determines whether to switch the charger mode based on whether the charging parameters meet preset conditions, demonstrating high intelligence. On one hand, it can determine whether to switch modes based on the electrical parameters at the charging interface when the charging parameters meet the preset conditions. This dual-judgment method can more accurately determine the current charging state and thus switch modes, reducing the inaccuracy of judging a single parameter. On the other hand, by adjusting the charger mode in a timely manner based on changes in both charging and electrical parameters, the charger can reduce the prolonged exposure to high voltage and high current, thereby reducing the charger's power consumption.

[0123] In some embodiments, the charging parameter is the charging current, and the electrical parameter at the charging interface of the charger is the voltage; the step of determining, based on the electrical parameter at the charging interface of the charger, to maintain the charger in the charging mode or switch the charger from the charging mode to the standby mode when the charging parameter meets preset conditions includes:

[0124] If the charger charges the charging device with a first current for a first preset duration and then charges the charging device with a second current for a second preset duration, based on the voltage at the charging interface of the charger, it is determined to maintain the charger in the charging mode or switch the charger from the charging mode to the standby mode.

[0125] Wherein, the first current is a current less than a first current threshold, the second current is a current less than a second current threshold, the first current threshold is greater than the second current threshold, and the first preset duration is greater than the second preset duration.

[0126] In this embodiment of the disclosure, when the electronic device charges the charging device with a first current for a first preset duration and then charges the charging device with a second current for a second preset duration, it determines, based on the voltage at the charging interface of the charger, whether to maintain the charger in charging mode or switch the charger from charging mode to standby mode. The first current threshold, the second current threshold, the first preset duration, and the second preset duration are all set values ​​that can be experimentally measured. The first preset duration can be 10 seconds, 8 seconds, etc., and the second preset duration can be 10 milliseconds, 8 milliseconds, etc. It should be noted that the first current threshold and / or the second current threshold may be different for different charger models. For example, the first current threshold may be 10mA, 9mA, etc., and the second current threshold may be 3mA, 100uA, etc.

[0127] In this embodiment of the present disclosure, taking a first current threshold of 10mA, a second current threshold of 100uA, a first preset duration of 8 seconds, and a second preset duration of 10 milliseconds as an example, if an electronic device charges a charging device with a current of less than 10mA for 8 seconds and then charges the charging device with a second current of less than 100uA for 10 milliseconds, the system determines, based on the voltage at the charging interface of the charger, whether to maintain the charger in charging mode or switch the charger from charging mode to standby mode.

[0128] In this embodiment of the disclosure, determining whether to maintain the charger in charging mode or switch the charger from charging mode to standby mode based on the voltage at the charger's charging port can be as described above. For example, in some embodiments, determining whether to maintain the charger in charging mode or switch the charger from charging mode to standby mode based on the voltage at the charger's charging port includes:

[0129] In response to the voltage at the charging port of the charger being less than or equal to a first voltage threshold, it is determined to maintain the charger in the charging mode;

[0130] In response to the voltage at the charging port of the charger being greater than the first voltage threshold and less than or equal to the second voltage threshold, the charger is switched from the charging mode to the standby mode.

[0131] In this embodiment of the disclosure, as mentioned above, the first voltage threshold can be a set value, such as one that can be measured experimentally, for example, the first voltage threshold can be 1V; the second voltage threshold can be the maximum voltage value that the charger can output at the charging interface in standby mode, for example, the second voltage threshold can be 3.3V.

[0132] In this embodiment of the disclosure, the electronic device determines to maintain the charger in charging mode in response to the voltage at the charging interface of the charger being less than or equal to a first voltage threshold. For example, when the first voltage threshold is 1V, the electronic device determines to maintain the charger in charging mode in response to the voltage at the charging interface of the charger being less than or equal to 1V.

[0133] In this embodiment of the disclosure, the electronic device switches the charger from charging mode to standby mode in response to the voltage at the charging interface of the charger being greater than a first voltage threshold and less than or equal to a second voltage threshold. For example, when the first voltage threshold is 1V and the second voltage threshold is 3.3V, the electronic device switches the charger from charging mode to standby mode in response to the voltage at the charging interface of the charger being greater than 1V and less than or equal to 3.3V.

[0134] In this embodiment, the charging current is first determined. If the duration of the charging current being the first current is greater than a first preset duration, and the duration of the charging current being the second current is greater than a second preset duration, the charger mode is determined based on the voltage at the charger's charging interface. This embodiment of the present invention, by determining the current twice, can improve the accuracy of determining whether to switch modes and has a high degree of intelligence.

[0135] It should be noted that this embodiment of the present disclosure uses a two-time current judgment method as an example, but it does not mean that this embodiment of the present disclosure only supports a two-time current judgment method. This embodiment of the present disclosure also supports a three-time, four-time or more-time current judgment method. This embodiment of the present disclosure does not limit this. For example, a third current threshold less than the second current threshold and a third preset duration less than the second preset duration can also be set. When the charger charges the charging device with the first current for a first preset duration, then charges the charging device with the second current for a second preset duration, and then charges the charging device with the third current less than the third current threshold for a third preset duration, the electronic device can determine, based on the voltage at the charging interface of the charger, whether to maintain the charger in the charging mode or switch the charger from the charging mode to the standby mode.

[0136] In some embodiments, the method further includes:

[0137] After the charger is switched from the charging mode to the standby mode, the number of times the charger switches between the standby mode and the charging mode within a third preset time period is determined.

[0138] In response to the charger switching to the charging mode and the number of switching times being greater than a preset threshold, the charger is kept in the charging mode until the charger is switched to a preset target charging device, and then it is determined whether to continue to maintain or switch the charging mode; wherein, the preset target charging device is a device associated with the preset charging protocol.

[0139] In this embodiment of the present disclosure, after the electronic device switches the charger from charging mode to standby mode, it determines the number of times the charger switches between standby mode and charging mode within a third preset time period. The third preset time period is a set value, such as 5 seconds, 10 seconds, etc. For example, when the third preset time period is 10 seconds, after the charger switches from charging mode to standby mode, it determines the number of times the charger switches between standby mode and charging mode within 10 seconds. For example, if the charger switches from standby mode to charging mode, then from charging mode to standby mode, and then from standby mode to charging mode again within 10 seconds, the number of switches is 3.

[0140] In this embodiment of the disclosure, the electronic device responds to the charger switching to charging mode and the number of switching times exceeds a preset threshold. The charger remains in charging mode until it is switched to a preset target charging device, at which point it determines whether to continue maintaining or switching the charging mode. The preset threshold is a set value, such as 2 times. If the charger switches to charging mode once or multiple times within a third preset time period, and the number of switching times exceeds the preset threshold, it indicates that the current charging device may be malfunctioning, and the charger needs to remain in charging mode to charge the current device. For example, if the preset threshold is 2 times and the third preset time period is 10 seconds, and the charger switches 3 times within 10 seconds, and the charger remains in charging mode after 3 switches, then the charger remains in charging mode. It should be noted that maintaining the charger in charging mode at this time means that regardless of whether the charger is connected to a charging device, it continuously outputs charging voltage and current, such as continuously outputting 5V.

[0141] In this embodiment of the disclosure, the electronic device maintains the charger in charging mode until the charger is switched to a preset target charging device, at which point it determines whether to continue maintaining or switching the charging mode. The preset target charging device is a device associated with a preset charging protocol. After determining that the charger has been switched to the preset target charging device, the electronic device can determine whether to continue maintaining or switching the charging mode based on changes in the communication signal between the charger and the preset target charging device. The method for determining whether to continue maintaining or switching the charging mode based on changes in the communication signal between the charger and the preset target charging device can be as described above.

[0142] In this embodiment of the disclosure, after the charger is switched from charging mode to standby mode, if the number of times the charger switches between standby mode and charging mode within a third preset time period exceeds a preset threshold, it indicates that the charger has performed multiple mode switches in a short period of time. This suggests that the charging device connected to the charger may be experiencing abnormal conditions such as overheating. Maintaining the charger in charging mode can reduce charging interruptions caused by charging device malfunctions, thereby reducing potential problems such as device shutdown or data loss due to insufficient power in the charging device. Furthermore, after the charger is switched to a preset target charging device, determining whether to continue maintaining or switching the charging mode can prevent the charger from continuously operating in a high-power charging mode, thus reducing the overall power consumption of the charger.
