Some embodiments will be described below with reference to the accompanying drawings. The following embodiments and features in the embodiments may be combined with each other without conflict.

Electronic devices such as personal computers are often charged via adapters. When the electronic device is in a high power consumption scenario, the output power of the adapter cannot meet the power demand of the electronic device, and the battery of the electronic device cannot supply power in time (for example, due to the slow response of the charging management chip, the battery cannot supply power in time), charging abnormalities are prone to occur. , if it is easy to cause the adapter to be pulled and hung, the adapter will stop charging.

For example, in high power consumption scenarios such as starting up the whole machine or processing game tasks, the processor calls (or calls frequently) high processing capabilities, the working frequency of the processor increases, and the power consumption of the processor increases accordingly, resulting in electronic The power requirements of the device increase. When the output power of the adapter cannot meet the power demand of the electronic device, such as the charging voltage output by the adapter is lower than the preset voltage threshold, the electronic device outputs a reset signal to the adapter. The adapter resets according to the reset signal, stops charging the electronic device connected to it, and after stopping charging, connects to the electronic device again to continue charging the electronic device. When implementing the embodiments of the present application, the inventor found that in high power consumption scenarios such as starting up the entire machine or processing game tasks, the output power of the adapter after reset is usually still unable to meet the power requirements of the electronic device, and the electronic device will still output a reset signal. , the adapter will still be disconnected from charging. When the electronic device frequently outputs reset signals to the adapter, it will cause the adapter to frequently disconnect from charging. Obviously, frequent interruption of charging by the adapter can easily lead to undercharging of electronic devices, frequent exit of performance mode, and switching of the displayed charging icon back and forth, thus affecting user use.

For example, the interaction of charging protocols, reset signals or control instructions is implemented between the electronic device 100 and the adapter 200 . The control instructions can be used to control the adapter 200 to provide corresponding charging voltage and/or charging current according to the needs of the electronic device 100 .

Among them, the power charging chip 102 is used to implement fast charging.

In the embodiment of the present application, the power charging chip 102 is a charging controller that complies with the PD charging protocol.

In the embodiment of the present application, when the charging voltage of the adapter 200 is less than or equal to the first voltage threshold value, the power charging chip 102 can trigger the adapter 200 to reset, such as hard reset. In some embodiments, to avoid false triggering, such as avoiding software failure or manual plug-in operation causing the charging voltage to be less than or equal to the first voltage threshold value and falsely triggering the power charging chip 102 to reset the adapter 200, the power charging chip 102 can be configured with a first time parameter.

In the embodiment of the present application, the power charging chip 102 needs to satisfy two conditions at the same time to reset the adapter 200: the charging voltage is less than or equal to the first voltage threshold, and the duration of the charging voltage being less than or equal to the first voltage threshold is greater than or equal to the first voltage threshold. Equal to the first time parameter.

In this embodiment of the present application, the first voltage threshold VPD and the first time parameter TDebounce time are parameters configured in the firmware of the power charging chip 102 . The first time parameter TDebounce time has its corresponding specification range, which is called the first specification range. The value corresponding to the first time parameter TDebounce time cannot exceed the first specification range.

In the embodiment of the present application, while ensuring that the value corresponding to the first time parameter TDebounce time does not exceed the first specification range, the value corresponding to the first time parameter TDebounce time can be flexibly adjusted.

Among them, the charging management chip 103 is used to monitor and control the charging process.

In this embodiment of the present application, the charging management chip 103 can monitor charging current, charging voltage, temperature and other parameters in real time, and control the charging process according to the set charging mode and protection mechanism.

In the embodiment of the present application, the charging management chip 103 can obtain the charging voltage and charging current output by the adapter 200 based on the connection with the external interface 101, and then the charging management chip 103 can notify the embedded controller 104 or the power charging chip 102 of the charging voltage and charging current of the adapter 200. Specifically, after the external interface 101 is connected to the adapter 200, the external interface 101 can notify the charging management chip 103 of the charging voltage and charging current of the adapter 200.

The adapter 200 can increase the charging current or decrease the charging current according to the control instruction.

In this embodiment of the present application, the charging management chip 103 may output a frequency reduction signal used to instruct the processor 106 to reduce frequency. Among them, the down-conversion signal includes but is not limited to: Prochot signal.

Please also refer to FIG. 3 . The first current parameter is used to indicate the current threshold value that triggers the charging management chip 103 to limit the charging current of the adapter 200 . The peak current is used to indicate the current threshold that triggers the charge management chip 103 to output the down-conversion signal to the processor 106 . The second time parameter is used to indicate the time threshold that triggers the charging management chip 103 to output the down-conversion signal to the processor 106 .

The relationship between the value of the first current parameter and the peak current can be: Peak current = The present application does not specifically limit the value of the first current parameter.

In this embodiment of the present application, when the charging current of the adapter 200 is greater than or equal to the first current parameter, the charging management chip 103 can limit the charging current output by the adapter 200 . In other words, when the charging current of the adapter 200 is greater than or equal to the first current parameter, the charging management chip 103 can output a control instruction for instructing to reduce the charging current to the adapter 200, so that the adapter 200 reduces the output charging according to the control instruction. current. The effective time for the charging management chip 103 to limit the output charging current of the adapter 200 depends on the response speed of the charging management chip 103 . When the response speed of the charging management chip 103 is slow and the charging current of the adapter 200 is greater than or equal to the first current parameter, the charging management chip 103 cannot promptly output a control instruction for instructing to reduce the charging current to the adapter 200 , that is, the charging management chip 103 If the charging current output by the adapter 200 cannot be limited in time, the charging current output by the adapter 200 will continue to rise. Therefore, there may be a situation where the charging current is greater than or equal to the peak current.

In the embodiment of the present application, when the charging current of the adapter 200 is greater than or equal to the peak current, the charging management chip 103 can trigger the processor 106 to reduce the frequency, that is, trigger the processor 106 to reduce the operating frequency. In other words, when the charging current of the adapter 200 is greater than or equal to the peak current, the charging management chip 103 can output a down-conversion signal to the processor 106 . In some embodiments, the charge management chip 103 may configure the second time parameter. By configuring the second time parameter, frequent triggering of the processor 106 to reduce frequency can be avoided, which affects the normal operation of the electronic device 100 .

In the embodiment of the present application, the charging management chip 103 triggers the processor 106 to reduce the frequency when two conditions are met at the same time: the charging current is greater than or equal to the peak current, and the duration of the charging current being greater than or equal to the peak current is greater than or equal to the second time parameter.

In the embodiment of the present application, the first current parameter ILIM2, the peak current ICRIT, and the second time parameter TICRIT Debounce time are all parameters configured in the firmware of the charging management chip 103. The first current parameter ILIM2 and the second time parameter TICRIT Debounce time have their corresponding specification ranges. The specification range corresponding to the first current parameter ILIM2 may be called the second specification range. The specification range corresponding to the second time parameter TICRIT Debounce time can be called the third specification range. The values corresponding to the first current parameter ILIM2 and the second time parameter TICRIT Debounce time cannot exceed their corresponding specification ranges.

In the embodiment of the present application, the first current can be flexibly adjusted while ensuring that the value corresponding to the first current parameter ILIM2 does not exceed the second specification range and the value corresponding to the second time parameter TICRIT Debounce time does not exceed the third specification range.

For example, the user inserts an adapter connected to a power supply (eg, mains power) into an external interface of the electronic device.

Step S502: The power charging chip obtains the charging voltage of the adapter.

In this embodiment of the present application, after the external interface of the electronic device is connected to the adapter, the power charging chip can collect the charging voltage of the adapter in real time. For example, the charging voltage of the adapter can be 20V. After the external interface of the electronic device is connected to the adapter, the power adapter uses the 20V charging voltage to charge the electronic device. Correspondingly, the power charging chip can obtain the charging voltage of the adapter to 20V.

Step S503: The embedded controller obtains the charging voltage of the adapter.

In this embodiment of the present application, the embedded controller can obtain the charging voltage collected by the power charging chip in real time. For example, take the power charging chip included in the electronic device as a first PD chip, and the power charging chip included in the adapter as a second PD chip. When the embedded controller of the electronic device is awakened, the embedded controller runs its corresponding control code logic and sends a power supply information query signaling to the first PD chip. The power supply information query signaling is used to query the power supply information of the adapter. Power supply information includes but is not limited to: charging voltage and charging current. The first PD chip sends the electrical information query signaling to the second PD chip to indicate a request to obtain the power supply information of the adapter. The corresponding message type may be Control:GetSink_Cap. The second PD chip returns the power supply information queried according to the power supply information query signaling to the first PD chip, and its corresponding message type may be Data: Sink Capability. The first PD chip can output the obtained power supply information to the embedded controller.

In the embodiment of the present application, when the adapter is connected to the electronic device, both the power charging chip and the charging management chip can obtain the charging voltage and/or charging current of the adapter. Therefore, the embedded controller can obtain the charging voltage of the adapter from the power charging chip or charging management chip in real time.

Step S504: When the power charging chip detects that the charging voltage is less than or equal to the first voltage threshold, and the duration for which the charging voltage is less than or equal to the first voltage threshold is greater than or equal to the first time parameter, it determines that the adapter has stopped charging and outputs Reset signal to adapter.

In this embodiment of the present application, the power charging chip detects that the charging voltage is less than or equal to the first voltage threshold, and the duration for which the charging voltage is less than or equal to the first voltage threshold is greater than or equal to the value stored in the firmware of the power charging chip. According to the value of the parameter at the first time, the power charging chip outputs a reset signal to the external interface, and then outputs the reset signal to the adapter through the external interface.

Step S505: The adapter resets according to the reset signal.

After the adapter receives the reset signal, it runs its corresponding control code logic to reset (reset) the adapter. When the adapter is reset, the adapter disconnects from the electronic device (that is, the adapter is disconnected and charged), and then re-establishes the connection with the electronic device.

Step S506: When the adapter is disconnected from charging, the embedded controller sends parameter request information to obtain the first parameter to the corresponding chip.

In this embodiment of the present application, the embedded controller can obtain the first voltage threshold value and the first time parameter in advance, and can further detect whether the adapter has stopped charging based on the charging voltage obtained in real time. When the embedded controller detects that the charging voltage is less than or equal to the first voltage threshold, and the duration of the charging voltage being less than or equal to the first voltage threshold is greater than or equal to the first time parameter, it is determined that the adapter has stopped charging.

In other embodiments, the embedded controller may determine that the adapter is disconnected from charging when the power charging chip outputs a reset signal.

The first parameter may include parameters related to adapter charging in the charging management chip and/or the power charging chip. Specifically, the first parameter includes but is not limited to: a first time parameter, a first current parameter and a second time parameter. The corresponding chips include any one or both of a charging management chip and a power charging chip.

The parameter request information may be used to indicate a request to obtain the first parameter, that is, the parameter request information indicates the first parameter to be obtained. In other embodiments, the parameter request information may also be used to indicate a request to obtain the specification range of the first parameter, that is, the parameter request information also indicates the specification range corresponding to the first parameter to be obtained. The specification range corresponding to the first parameter may refer to the content of the specification range corresponding to each parameter mentioned above, which will not be described again here.

The following takes the parameter request information only for instructing to obtain the first parameter as an example. When performing step S506, the embedded controller may send the parameter request information for obtaining the first time parameter to the power charging chip to obtain the parameter in the power charging chip. First time parameters. Alternatively, the embedded controller may send parameter request information for obtaining the first current parameter to the charging management chip to obtain the first current parameter in the charging management chip. Alternatively, the embedded controller can send parameter request information to obtain the first time parameter to the power charging chip to obtain the first time parameter, and at the same time send parameter request information to obtain the first current parameter and the second time parameter to the charging management chip, To obtain the first current parameter and the second time parameter, this application does not specifically limit this.

It can be understood that when the parameter request information is used to indicate a request to obtain a first parameter and a specification range corresponding to the first parameter, the embedded controller can send a parameter request information to a certain chip once, and can simultaneously obtain the first parameter in the chip and the specification range corresponding to the first parameter. Taking the example of sending a parameter request information to obtain a first time parameter to a power charging chip, the parameter request information indicates obtaining the first time parameter and the first specification range. The same applies to other cases.

In other embodiments, the parameter request information is only used to indicate obtaining the first parameter, and the specification range request information is only used to indicate obtaining the specification range corresponding to the first parameter. Then the embedded controller needs to send request information to a certain chip at least twice to obtain the first parameter in the chip and the specification range corresponding to the first parameter. The timing of sending parameter request information by the embedded controller depends on the specification range. The timing of requesting information can be the same or different, and can be set according to the actual situation. This application does not specifically limit this.

Step S507: The corresponding chip transmits the first parameter to the embedded controller.

In this embodiment of the present application, in step S506, the embedded controller sends parameter request information to the corresponding chip, and the corresponding chip feeds back corresponding information according to the parameter request information, such as feeding back the first parameter, or feeding back the first parameter and the third parameter. The specification range corresponding to a parameter.

For example, in step S506, the embedded controller sends parameter request information to obtain the first time parameter and the specification range of the first time parameter to the power charging chip. Then in step S507, the power charging chip transmits the data to the embedded controller. First time parameters and first specification range. For another example, in step S506, the embedded controller sends parameter request information to obtain the first current parameter and the specification range of the first current parameter to the charging management chip. Then in step S507, the charging management chip sends a request message to the embedded controller. The first current parameter and the second specification range are transmitted. For another example, in step S506, the embedded controller sends the parameter information of obtaining the first current parameter, the second time parameter and the corresponding specification range to the charging management chip, and also sends the obtaining of the first time parameter and the corresponding specification range to the power charging chip. Parameter request information for the specification range of the first time parameter, then in step S507, the charging management chip transmits the first current parameter, the second time parameter, the second specification range and the third specification range to the embedded controller, and the power supply The charging chip transmits the first time parameters and the first specification range to the embedded controller.

It can be understood that when the embedded controller sends to the corresponding chip to obtain part or all of its first parameters, the corresponding chip returns part or all of its first parameters and the specification range of the returned first parameters to the embedded controller.

Step S508: The embedded controller adjusts the first parameter.

In this embodiment of the present application, when the adapter is disconnected from charging, the embedded controller adjusts the first parameter. Specifically, the embedded controller adjusts the first parameters transmitted in step S507. For example, all the first parameters transmitted in step S507 can be adjusted, or part of the first parameters transmitted in step S507 can be adjusted. Make adjustments.

In this embodiment of the present application, adjusting the first parameter includes but is not limited to: increasing the value of the first parameter, decreasing the value of the first parameter, or maintaining the value of the first parameter. For example, the embedded controller may increase the value of the first time parameter within the first specification range. For another example, the embedded controller may reduce the value of the first current parameter within the second specification range. For another example, the embedded controller can increase the gear of the second time parameter within the third specification range.

In the embodiment of this application, the content of the embedded controller adjusting the first parameter will be introduced in detail below.

It is understandable that the power charging chip and the embedded controller can simultaneously determine that the adapter is disconnected from charging. The execution order of steps S504 and S506 and steps S505 and S506 is not specifically limited, and steps S504 and S506 can be executed simultaneously, or steps S505 and S506 can be executed simultaneously.

In step S509, the embedded controller outputs the adjusted first parameter to the corresponding chip.

In the embodiment of the present application, after the first parameter is adjusted in step S508, in step S509, the first parameter adjusted in step S508 is output to the corresponding chip.

For example, in step S508, the embedded controller adjusts the first current parameter of the charging management chip, and in step S509, the embedded controller transmits the adjusted first current parameter to the charging management chip. For another example, in step S508, the embedded controller adjusts the first time parameter of the power charging chip, and in step S509, the embedded controller transmits the adjusted first time parameter to the power charging chip. For another example, in step S508, the embedded controller adjusts the first current parameter, the second time parameter of the charging management chip, and the first time parameter of the power charging chip, and in step S509, the embedded controller transmits the adjusted first current parameter and the adjusted second time parameter to the charging management chip, and transmits the adjusted first time parameter to the power charging chip.

In step S510, the corresponding chip operates according to the received adjusted first parameter.

In this embodiment of the present application, after the embedded controller outputs the adjusted first parameter to the corresponding chip in step S508, the corresponding chip operates according to the adjusted first parameter.

For example, in step S508, the embedded controller adjusts the first time parameter, and in step S510, when the charging voltage is less than the first voltage threshold, the power charging chip determines whether to output reset information based on the adjusted first time parameter. For another example, in step S508, the embedded controller adjusts the first current parameter, and in step S510, the charging management chip controls the adapter to output a corresponding charging current according to the adjusted first current parameter. For another example, in step S508, the embedded controller adjusts the second time parameter. Then in step S510, when the charging current is greater than or equal to the peak current, the charging management chip determines whether to trigger processor downclocking based on the adjusted second time parameter. .

Step S511: After adjusting the first parameter, the embedded controller monitors whether the adapter has been disconnected and recharged.

In the embodiment of the present application, after adjusting the first parameter, the corresponding chip operates according to the received adjusted first parameter. When or after the corresponding chip runs according to the received adjusted first parameter, the embedded controller can determine whether the adapter has resumed charging after the charging voltage is obtained in real time. When it is detected that the charging voltage is greater than the first voltage threshold, the adapter stops charging and resumes charging. If it is detected that the charging voltage is less than or equal to the first voltage threshold, the adapter has stopped charging and has not recovered.

Step S512: When resuming from charging, the embedded controller writes the adjusted first parameter into the firmware of the corresponding chip.

Among them, the embedded controller writes the adjusted first parameter into the firmware of the corresponding chip, and the value of the corresponding first parameter in the firmware can be set to the value of the adjusted first parameter by burning or updating the firmware. .

In the embodiment of the present application, the adjusted first parameters include all first parameters adjusted by the embedded controller during the period from when the adapter is disconnected from charging to when the adapter is restored from charging, and the adjusted first parameters are The value is the parameter value of the chip when the adapter is disconnected and restored.

For example, during the period from when the adapter stops charging to when the adapter stops charging, the embedded controller adjusts the value of the first time parameter from the original fixed value a to b, and when the power charging chip operates according to the value b of the first time parameter, it detects that the adapter has not been restored from charging. The embedded controller continues to adjust the value of the first current parameter to c. When the power charging chip operates according to the value b of the first time parameter and the charging management chip operates according to the value c of the first current parameter, it is detected that the adapter has been restored from charging, the embedded controller sets the value of the first time parameter in the firmware of the power charging chip to b, and sets the value of the first current parameter in the firmware of the charging management chip to c.

For another example, as in the above example, when the power charging chip operates according to the value of the first time parameter b, the adapter is disconnected and not restored, the embedded controller adjusts the value of the first time parameter to the original fixed value a, and continues to adjust the value of the first current parameter to c. When the power charging chip operates according to the value of the first time parameter a, and the charging management chip operates according to the value of the first current parameter c, and it is detected that the adapter is disconnected and restored, the embedded controller maintains the value of the first time parameter in the firmware of the power charging chip as the original fixed value a, and sets the value of the first current parameter in the firmware of the charging management chip to c.

For another example, during the period from when the adapter is disconnected from charging to when the adapter is restored from charging, the embedded controller only adjusts the first current parameter of the charging management chip, and when the charging management chip runs according to the value of the first parameter to A, it detects When the adapter resumes charging after disconnection, the value of the first current parameter in the firmware of the charging management chip is set to A.

It can be understood that steps S506, S507, S509, S510, and S512 in Figure 5 take the corresponding chips including a charging management chip and a power charging chip as an example, and do not specifically limit the adjustment of the first parameter in the embodiment of the present application.

Step S513: When the adapter is disconnected and charged but has not recovered and the adapter is determined to be faulty, the embedded controller outputs fault information to the basic input and output system.

In the embodiment of the present application, the embedded controller can determine the adapter failure according to the adjusted parameters and the adapter charging failure. When the adapter fails, the embedded controller can output the fault information to the basic input and output system, so as to report it to the corresponding application (such as computer manager) through the basic input and output system, and then upload it to the background through the corresponding application, so as to notify the background staff in time.

The charging abnormality handling method provided by the embodiments of this application includes but is not limited to the following technical effects:

In the embodiment of the present application, when the electronic device is charged through the adapter, the electronic device can automatically detect the adapter charging failure, and flexibly adjust the values corresponding to the first time parameter, the first current parameter and the second time parameter when the adapter is disconnected, as The current charging configuration between the electronic device and the adapter has the most appropriate parameter values to repair the adapter's disconnected charging.

Please refer to Figure 6, which exemplarily introduces another charging exception handling method flow provided in an embodiment of the present application. The charging exception handling method can be applied to the above-mentioned electronic device, and specifically, can be executed by an embedded controller. The method flow includes steps S601 to S606. Among them, the content of step S602 can refer to the above-mentioned steps S509 and S510, the content of step S603 can refer to the above-mentioned step S511, and the content of step S604 can refer to the above-mentioned step S512, which will not be repeated here.

Step S601: When the adapter is disconnected from charging, the embedded controller adaptively adjusts one or more of the first time parameter, the first current parameter, and the second time parameter.

In this embodiment of the present application, the embedded controller can obtain the charging voltage obtained by the power charging chip in real time, and determine whether the adapter has stopped charging based on the charging voltage. In other embodiments, the embedded controller may determine whether the adapter is disconnected from charging based on the presence status of the adapter notified by the charging management chip. Specifically, when the adapter is inserted into the external interface, the external interface notifies the charging management chip of the level change and charging voltage of the charging management chip. According to the level change, it is determined that there is an insertion event in the external interface. According to the charging voltage, it is determined that the adapter is inserted into the external interface, and then the charging management is performed. The chip confirms that the adapter is in place. The charging management chip notifies the embedded controller of the presence of the adapter, and the embedded controller can determine whether the adapter is disconnected from charging based on the presence of the adapter.

It can be understood that the embedded controller can also determine whether the adapter is out of charge in other ways, which is not specifically limited in the embodiments of this application.

In this embodiment of the present application, the embedded controller adjusting the first parameter includes but is not limited to: increasing the value of the first time parameter, decreasing the value of the first current parameter, and increasing the gear of the second time parameter. The embedded controller adaptively performs one or more of the following operations: increasing the value of the first time parameter, decreasing the value of the first current parameter, and increasing the gear of the second time parameter.

Please refer to Figure 3 as well, for an exemplary introduction to the principle of adjusting the first parameter provided by the embodiment of the present application.

In the embodiment of the present application, if the first parameter is not adjusted, such as increasing the value of the first time parameter TDebounce time, reducing the value of the first current parameter, or increasing the gear of the second time parameter, once the charging voltage VBUS is less than or is equal to the first voltage threshold value VPD, and the charging voltage VBUS is less than or equal to the first voltage threshold value VPD and the duration is greater than or equal to the original value of the first time parameter TDebounce time, the power charging chip will reset the adapter, causing the adapter to disconnect Charging, the adapter cannot provide more energy to electronic devices. At the same time, if the response speed of the charging management chip is slow, the battery of the electronic device will not be able to power the electronic device in time, affecting the normal operation of the electronic device.

In the embodiment of the present application, compared to the value of the first time parameter TDebounce time that is not increased, the value of the first time parameter TDebounce time is increased in the embedded controller, and the power charging chip operates according to the increased value of the first time parameter TDebounce time. , after the charging voltage VBUS is less than the first voltage threshold value VPD, the power charging chip needs more time to output the reset signal to the adapter. That is to say, increasing the value of the first time parameter TDebouncetime can reduce the frequency of the reset signal output by the power charging chip, and accordingly reduce the frequency of the adapter charging interruption.

Further, as shown in Figure 3, after increasing the value of the first time parameter TDebounce time, the charging current IBUS can be increased even more, which means that the adapter can provide more power for electronic devices and ensure the output capability of the adapter. and the proper functioning of electronic equipment.

Further, when the charging current IBUS continues to rise to be greater than or equal to the first current parameter ILIM2, the charging management chip may not respond in time due to the slow response speed of the charging management chip. After increasing the value of the first time parameter TDebounce time, more time can be provided for the charging management chip to respond. That is, delayed reset can increase the probability that the charging management chip triggers the adapter to reduce the charging current IBUS and triggers the battery to output electric energy. After the adapter reduces the charging current IBUS, the charging voltage VBUS of the adapter rises, and the charging voltage VBUS can be greater than the first voltage threshold value VPD, thereby resuming charging interruption, and at the same time, the battery outputs electric energy to ensure the normal operation of the electronic device.

In the embodiment of the present application, after reducing the value of the first current parameter ILIM2, the charging management chip can be triggered to limit the charging current IBUS more quickly, that is, the charging management chip can be triggered to output a control instruction to the adapter more quickly, so that the adapter reduces the charging current IBUS. When the charging current IBUS is reduced, the charging voltage VBUS of the adapter rises accordingly, and the rising charging voltage VBUS can be greater than the first voltage threshold value VPD, thereby making the condition for the power charging chip to output a reset signal to the adapter unsatisfied, that is, the adapter is disconnected and restored.

Furthermore, after reducing the value of the first current parameter ILIM2, the charge management chip can be triggered faster to control the battery to output electric energy, thereby providing electric energy to the electronic device faster and ensuring the normal operation of the electronic device.

In an embodiment of the present application, after increasing the gear position of the second time parameter TICRIT Debounce time, the probability of the charging management chip triggering the processor frequency limiting decreases, providing more time for the slow-responding charging management chip to respond. That is, by delaying the processor frequency reduction, the probability of the charging management chip triggering the adapter to reduce the charging current IBUS and the probability of triggering the battery to output electrical energy can be increased. After the adapter reduces the charging current IBUS, the charging voltage VBUS of the adapter rises, and then the charging voltage VBUS can be greater than the first voltage threshold value VPD, thereby restoring the charging interruption, and at the same time, the battery output power can ensure the normal operation of the electronic device.

Step S602: The embedded controller transmits the adjusted first parameter to the corresponding chip, so that the corresponding chip operates according to the adjusted first parameter.

In the embodiment of the present application, the embedded controller adjusts one or more of the first time parameter, the first current parameter and the second time parameter, and the corresponding chip can be one of a charging management chip and a power charging chip or Multiple. When the corresponding chip includes a power charging chip, the adjusted first time parameters are transmitted to the power charging chip. When the corresponding chip includes a charging management chip, one or more of the adjusted first current parameters and second time parameters are transmitted to the charging management chip.

Step S603: After adjusting the first parameter, the embedded controller obtains the charging and disconnection status of the adapter.

In this embodiment of the present application, after the embedded controller adjusts the value of the first parameter, the corresponding chip operates according to the adjusted value of the first parameter, and then the embedded controller can determine the charging status of the adapter according to the charging voltage. When the charging voltage changes from less than or equal to the first voltage threshold value to greater than the first voltage threshold value, the charging interruption situation is a charging interruption recovery. When the charging voltage is always less than or equal to the first voltage threshold value, the charging interruption situation is that charging is not resumed.

Step S604: When the charging interruption situation is a charging interruption recovery, the embedded controller writes the adjusted first parameter into the corresponding firmware.

Step S605 , when the charging interruption condition is that the charging is interrupted and not restored, the embedded controller determines whether the current first time parameter and the current first current parameter are both beyond the corresponding specification range.

When the charging is disconnected and not restored, the embedded controller determines whether the current first time parameter exceeds the first specification range and whether the current first current parameter exceeds the second specification range. If the current first time parameter exceeds the first specification range and the current first current parameter exceeds the second specification range, the embedded controller executes step S606. Under the condition that the current first time parameter exceeds the first specification range and the current first current parameter exceeds the second specification range, the embedded controller repeats step S601. That is, if the current first time parameter does not exceed the first specification range, or the current first current parameter does not exceed the second specification range, or the current first time parameter does not exceed the first specification range and the current first current parameter does not exceed the second specification range, the embedded controller repeats step S601.

It can be understood that when performing step S605, if the embedded controller has only adjusted the first time parameter or only adjusted the first current parameter, it is obvious that the other unadjusted parameter does not exceed the corresponding specification range, that is, it does not meet the current Both the first time parameter and the current first current parameter exceed the corresponding specification range, so step S601 is repeatedly executed.

The current first time parameter is the value of the first time parameter at the current moment such as when step S605 is executed, and correspondingly, the current first current parameter is the value of the first current parameter at the current moment such as when step S605 is executed. The current first time parameter or the current first current parameter can be the value after parameter adjustment when step S605 is executed, or it can be the original fixed value that has not been adjusted.

It can be understood that when the embedded controller repeatedly executes step S601, the first parameter adjusted by the embedded controller may be the same as or different from the first parameter adjusted previously. For example, taking the embedded controller adjusting the first time parameter as an example, when the embedded controller needs to repeat step S601 after executing step S605, the embedded controller can continue to adjust the first time parameter or adjust the first current. parameter or adjust the second time parameter.

It should be noted that during the period when the embedded controller adjusts the first parameter to the embedded controller to obtain the disconnection and charging status of the adapter after the corresponding chip operates according to the adjusted first parameter, as described above in step S601 to step S603, for a certain device, The first parameter, adjust the value of the first parameter only once. In other words, for a certain first parameter, after adjusting the value of the first parameter, the corresponding chip will operate according to the value of the adjusted first parameter, and then the embedded controller obtains the disconnection and charging status of the adapter, and when the value is disconnected, When the charge is not restored, the next value adjustment can be made for the first parameter.

Step S606: The embedded controller determines that the adapter is faulty and outputs the fault information to the basic input and output system.

In the embodiment of this application, when the embedded controller determines that the adapter is faulty, the embedded controller can first report the fault information to the background, and then report the fault information to the computer manager.

The charging abnormality handling method provided by the embodiments of this application includes but is not limited to the following technical effects:

In the embodiment of the present application, when the adapter fails to charge, the embedded controller flexibly adjusts the values corresponding to the first time parameter, the first current parameter, and the second time parameter to configure the most appropriate parameter values for the current situation to repair the adapter failure while ensuring the normal operation of the electronic device.

In some embodiments, the embedded controller may adjust the first parameter according to preset rules. Specifically, the embedded controller increases the first time parameter according to the first preset rule, and/or the embedded controller decreases the first current parameter according to the second preset rule, and/or the embedded controller increases the first time parameter according to the second preset rule. Three preset rules add a second time parameter. The first preset rule, the second preset rule and the third preset rule may be the same or different.

In the embodiment of the present application, the embedded controller increasing the first time parameter according to the first preset rule includes: the embedded controller obtains the first adjustment value, and increases the current value of the first time parameter by the first adjustment value, obtaining Adjusted first time parameters. The current value of the first time parameter is the value of the first time parameter obtained when the first time parameter is added. It can be the original fixed value of the first time parameter that has not yet been adjusted, or it can be the value obtained after the last adjustment. The value of the adjusted first time parameter. The first adjustment value is the preset percentage of the current difference. The current difference is the maximum value within the specification range of the first time parameter minus the current value of the first time parameter. the difference obtained.

In an embodiment of the present application, the embedded controller reduces the first current parameter according to the second preset rule, including: the embedded controller obtains the second adjustment value, and subtracts the second adjustment value from the current value of the first current parameter to obtain the adjusted first time parameter. The current value of the first current parameter is the value of the first current parameter obtained when the first current parameter is reduced, which can be the original fixed value of the first current parameter that has not been adjusted, or the value of the adjusted first current parameter obtained after the last adjustment, the second adjustment value is a preset percentage of the current difference, and the current difference is the difference obtained by subtracting the current value of the first current parameter from the maximum value within the specification range of the first current parameter.

The third preset rule may be to increase the gear of the second time parameter in sequence. The embedded controller increases the second time parameter according to the third preset rule, including: increasing the current gear of the second time parameter to the next gear.

The preset percentage may be 3%, 4%, 5%, etc., which is not specifically limited in this application. The preset percentage corresponding to the first adjustment value may be the same as or different from the percentage corresponding to the second adjustment value, which is not specifically limited in this application.

In the embodiment of the present application, the embedded controller adjusts the corresponding first parameter according to the corresponding preset rule, and the corresponding chip operates according to the value of the adjusted first parameter. When the adapter is disconnected and charging has not been restored, the embedded controller Then adjust the corresponding first parameter according to the corresponding preset rule, and so on. For example, taking the current value of the first time parameter as 2s, the maximum value within the first specification range as 6s, and the preset percentage as 5%, the first adjustment value is calculated as , then the value after the embedded controller adds the first time parameter is 2s +0.2s=2.2s, and the power charging chip operates according to the value of the first time parameter which is 2.2s. It is detected that the running adapter with the value of the first time parameter is 2.2s and has not recovered after being disconnected and charged. The embedded controller adjusts the corresponding first parameter according to the corresponding preset rules. The current value of the first time parameter is the last adjustment. After 2.2s, the first adjustment value is calculated as/> , then the value after the embedded controller adds the first time parameter is 2.2s +0.19s=2.39s, and the power charging chip operates according to the value of the first time parameter 2.39s, and so on.

Please refer to FIG. 7 for an exemplary introduction to the method flow of adjusting the first parameter provided by the embodiment of the present application. The charging abnormality processing method can be applied to the above-mentioned electronic device, and specifically, can be executed by an embedded controller. The method flow includes steps S701 to step S713. The content of steps S701 to step S704, step S706 to step S709, and step S711 to step S716 can be referred to the above, and will not be described again here.

Step S701: The embedded controller adds a first time parameter according to a first preset rule.

In step S702, the embedded controller transmits the increased first time parameter to the power charging chip, so that the power charging chip operates according to the increased first time parameter.

Step S703: After adding the first time parameter, the embedded controller obtains the charging disconnection status of the adapter.

Step S704: When the charging interruption situation is a charging interruption recovery, the embedded controller writes the adjusted first time parameters into the firmware of the power charging chip.

Step S705: When the charging situation is that charging has not been restored, the embedded controller determines whether the number of times of adjusting the first time parameter reaches the first threshold.

In this embodiment of the present application, for each first parameter, an adjustment number threshold is set. Set a first threshold for the first time parameter. The first threshold is used to indicate that when the number of times of continuous adjustment of the first time parameter reaches the first threshold and the charging situation is not restored, other first parameters other than the first time parameter, such as the first current parameter or the second time, are adjusted. parameter. The first threshold is greater than or equal to 1.

In the embodiment of the present application, while adjusting the first time parameter, the embedded controller accumulates the number of times the first time parameter is adjusted, so that after adjusting the first time parameter, the interruption of charging is detected as the interruption of charging has not been restored, and the adjustment is determined. Whether the number of times of the first time parameter reaches the first threshold. If not, the embedded controller repeats step S701. If so, the embedded controller can adjust other first parameters except the first time parameter, such as the embedded controller executing step S706.

In some embodiments, when the embedded controller adjusts other first parameters except the first time parameter, the recorded number of times the first time parameter is adjusted can be cleared so that the number of times the first time parameter is adjusted can be re-counted the next time the first time parameter is adjusted.

Step S706: The embedded controller reduces the first current parameter according to the second preset rule.

In step S707, the embedded controller transmits the reduced first current parameter to the charging management chip, so that the charging management chip operates according to the reduced first current parameter.

Step S708: After reducing the first current parameter, the embedded controller obtains the charging disconnection status of the adapter.

Step S709: When the charging interruption situation is a charging interruption recovery, the embedded controller writes the adjusted first parameter into the firmware of the corresponding chip.

The adjusted first parameter in step S709 may include the adjusted first time parameter and the adjusted first current parameter. Step S709 may specifically include: writing the value of the first parameter running in the charging management chip and the power charging chip into the firmware of the corresponding chip when the charging is resumed.

Step S710: When the charging interruption situation is that the charging interruption has not been restored, the embedded controller determines whether the number of times of adjusting the first current parameter reaches the second threshold.

In this embodiment of the present application, a second threshold is set for the first current parameter. The second threshold is used to indicate that when the number of times of continuous adjustment of the first current parameter reaches the second threshold and the charge interruption situation is not restored, other first parameters other than the first current parameter, such as the first time parameter or the second time, are adjusted. parameter. The second threshold is greater than or equal to 1.

In the embodiment of the present application, while adjusting the first current parameter, the embedded controller accumulates the number of times the first current parameter is adjusted, so that after adjusting the first current parameter, the discontinuation of charging is detected as the discontinuation of charging and unrecovered charging, and it is determined that the first current parameter has been adjusted. Whether the number of times of a current parameter reaches the second threshold. If not, the embedded controller repeats step S706. If so, the embedded controller can adjust other first parameters except the first current parameter. For example, the embedded controller performs step S701 or step S713, and can also determine whether the adjusted parameter exceeds the corresponding specification. For example, the embedded controller executes step S711.

In some embodiments, when the embedded controller adjusts other first parameters except the first current parameter, the recorded number of times of adjusting the first current parameter can be cleared so that the next time the first current parameter is adjusted , the number of times of adjusting the first current parameter can be re-counted.

Step S711, the embedded controller determines whether the current first time parameter and the current first current parameter both exceed the corresponding specification range.

If both the current first time parameter and the current first current parameter exceed the corresponding specification range, the embedded controller executes step S712. If both the current first time parameter and the current first current parameter do not meet the corresponding specification range, the embedded controller may execute step S713, step S701, or step S706.

In some embodiments, the proportion of adjusting the first time parameter and the first current parameter may be increased. The adjustment phase of the first parameter includes starting to adjust the first parameter and ending the adjustment of the first parameter for the first time. Illustratively, the adjustment stage of the first time parameter includes steps S701 to S705, and the judgment result is yes. Correspondingly, the adjustment stage of the first current parameter includes steps S706 to S710 and the determination result is yes.

After both the first time parameter and the first current parameter have gone through an adjustment stage, the adjustment of one or both of the first time parameter and the first current parameter may continue to be repeatedly performed to repeat the adjustment stage of the first time parameter. And/or when the number of times the adjustment phase of the first current parameter is repeated reaches the preset times threshold and charging is not resumed, the adjustment of the second time parameter is performed. Among them, the preset times threshold can be 2, 3, etc.

In some embodiments, when the number of times the first time parameter adjustment phase is repeated reaches a preset number threshold, it can be ensured that the adjusted first time parameter does not exceed the first specification range. Correspondingly, when the number of times of repeating the adjustment phase of the first current parameter reaches the preset number threshold, it can be ensured that the adjusted first current parameter does not exceed the second specification range.

If so, in step S712, the embedded controller determines that the adapter is faulty and outputs the fault information to the basic input and output system.

If not, in step S713, the embedded controller adds the second time parameter according to the third preset rule.

In step S714, the embedded controller transmits the increased second time parameter to the charging management chip, so that the charging management chip operates according to the increased second time parameter.

Step S715, after adding the second time parameter, the embedded controller obtains the charging disconnection status of the adapter.

Step S716: When the charging interruption situation is a charging interruption recovery, the embedded controller writes the adjusted first parameter into the firmware of the power charging chip.

Step S717, when the charging interruption condition is that the charging is interrupted and not restored, the embedded controller determines whether the number of times the second time parameter is adjusted reaches a third threshold.

In this embodiment of the present application, a third threshold is set for the second time parameter. The third threshold is used to indicate that when the number of times of continuous adjustment of the second time parameter reaches the third threshold and the charging situation is not restored, other first parameters other than the second time parameter, such as the first time parameter or the first current, are adjusted. parameter. The third threshold is greater than or equal to 1.

In the embodiment of the present application, while adjusting the second time parameter, the embedded controller accumulates the number of times the second time parameter is adjusted, so that after adjusting the second time parameter, the interruption of charging is detected as the interruption of charging has not been restored, and it is judged to adjust the second time parameter. Whether the number of times of the second time parameter reaches the third threshold. If not, the embedded controller repeats step S713. If so, the embedded controller can adjust other first parameters except the second time parameter, such as the embedded controller performing step S701 or step S706.

In some embodiments, when the embedded controller adjusts other first parameters except the second time parameter, the recorded number of times of adjusting the second time parameter can be cleared so that the next time the second time parameter is adjusted, , the number of times of adjusting the second time parameter can be re-counted.

In some embodiments, the first threshold and/or the second threshold can be set to be greater than or equal to 2 to increase the proportion of the embedded controller adjusting the first time parameter and/or the first current parameter, giving priority to adjusting the first time parameter and/or the first current parameter. A time parameter and/or a first current parameter are used to repair adapter disconnection. The first threshold and the second threshold may be the same or different, and this is not specifically limited in the embodiments of the present application.

In some embodiments, when the charging interruption situation in step S704, step S709 or step S716 is charging interruption recovery, the embedded controller obtains feedback from the processor or charging management chip to determine whether the adjusted first parameter is correct based on the feedback. Processor performance is affected. If there is no impact, the adjusted first parameter is written into the firmware of the power charging chip. If there is an impact, readjust the first parameter, such as executing step S701, step S706, or step S713. Specifically, when the adjusted first parameter affects the performance of the processor, the charge management chip will be caused to send the Prochot signal to the processor. The charging management chip determines the impact on performance based on sending the Prochot signal, and the processor determines the impact on performance based on the received Prochot signal.
