Description

Technical Field

[0001] This application belongs to the technical field of charging, and particularly relates to a charging method, a charging device, an electronic device, and a readable storage medium. Background Art

[0002] Currently, in some areas with unstable power grids, when a user charges a mobile phone using a charger, the output voltage Vbus of the charger frequently spikes instantaneously.

[0003] For a situation where Vbus spikes instantaneously once, when the peak voltage corresponding to Vbus is greater than the threshold value of the mobile phone charging voltage, the overvoltage protection (OVP; overvoltage protection) circuit set in the mobile phone is triggered. At this time, the OVP circuit disconnects the charging path between the charger and the mobile phone for a period of time. In this way, the charging icon on the mobile phone disappears during this period of time. And, after this period of time, the OVP circuit restores the charging path between the charger and the mobile phone, so that the charging icon on the mobile phone appears again.

[0004] Combined with the above content, it can be seen that when Vbus frequently spikes instantaneously, the OVP circuit is frequently triggered, which causes the charging path between the charger and the mobile phone to be frequently disconnected. On this basis, the charging icon on the mobile phone will frequently disappear, which reduces the user experience of using the mobile phone. In addition, the continuous and frequent disconnection of the charging path between the charger and the mobile phone may cause the charging path between the charger and the mobile phone not to be restored, and at this time the charging icon will not be restored either, unless the user replugs the charger, which will cause the user to misbelieve that the mobile phone is damaged, thereby further reducing the user experience of using the mobile phone. Summary of the Invention

[0005] The purpose of the embodiments of this application is to provide a charging method, device, equipment, and readable storage medium, which can solve the problem of reduced user experience of using the mobile phone caused by the frequent disappearance of the charging icon on the mobile phone when the power grid is unstable, and the problem of reduced user experience of using the mobile phone caused by the user misbelieving that the mobile phone is damaged when the charging icon is no longer restored.

When the program or instruction is executed by the processor, the steps of the charging method described in the first aspect are implemented.

[0015] In a fourth aspect, an embodiment of the present application provides a readable storage medium, on which a program or instruction is stored. When the program or instruction is executed by a processor, the steps of the charging method described in the first aspect are implemented.

[0016] In a fifth aspect, an embodiment of the present application provides a chip, which includes a processor and a communication interface. The communication interface is coupled to the processor, and the processor is configured to run a program or instruction to implement the method described in the first aspect.

[0017] In an embodiment of the present application, a charging method is provided. The method is applied to an electronic device and includes: obtaining a charging voltage value of the electronic device; when the charging voltage value is zero, monitoring the duration for which the charging voltage value remains zero; and when the duration is within a preset duration range, controlling the charger connected to the electronic device to reduce the current power supply voltage value, and / or controlling the overvoltage protection circuit in the electronic device to increase the current voltage threshold value. By this method, when the power grid is unstable, the possibility of frequent disconnection of the charging path between the charger and the mobile phone can be reduced. On the one hand, this can reduce the possibility of the charging icon on the electronic device disappearing frequently, thereby improving the user experience of using the device. On the other hand, it can reduce the possibility that the charging path between the charger and the mobile phone will no longer recover due to continuous frequent disconnection of the charging path between the charger and the mobile phone, which reduces the possibility that the charging icon will no longer recover, and thus reduces the possibility that the user mistakenly believes that the mobile phone is damaged, thereby improving the user experience of using the device.

[0023] The following will clearly describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application belong to the scope of protection of the present application.

[0024] The terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of this application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / ", generally represents an "or" relationship between the associated objects before and after.

[0025] The following will combine the accompanying drawings and specifically illustrate the charging method, device, equipment and storage medium provided by the embodiments of this application through specific embodiments and their application scenarios.

[0026] The embodiments of this application provide a charging method, which is applied to an electronic device. As Figure 1 shown, the charging method provided by the embodiments of this application includes the following S1100-S1300:

[0027] S1100. Obtain the charging voltage value of the electronic device.

[0028] In this embodiment, the charging voltage value is the voltage value of the voltage applied to the positive electrode of the battery in the electronic device.

[0029] In this embodiment, the obtaining in S1100 above can be obtained at a fixed period, or obtained in real time, etc., and this application does not make any limitations on this.

[0030] S1200. When the charging voltage value is zero, monitor the duration for which the charging voltage value remains zero.

[0031] In this embodiment, when the charging voltage value is zero, it means that the electronic device is in one of the following three scenarios:

[0032] Scenario 1: The user does not charge the electronic device, or the user repeatedly plugs and unpluggs the charger.

[0033] Scenario 2: Due to unstable power grid, the power supply voltage provided by the charger to the electronic device fluctuates, resulting in the power supply voltage value provided by the charger to the electronic device exceeding the voltage threshold of OVP, and then causing OVP to disconnect the charging path between the charger and the electronic device.

[0034] Scenario 3: Instantaneous mis-acquisition.

[0035] It can be understood that, for the above three scenarios, the duration during which the charging voltage value is zero is different for each, and the difference is large. Specifically, for Scenario 1, the duration during which the charging voltage value is zero is usually at least several hundred milliseconds or more. For Scenario 2, the duration during which the charging voltage value is zero is usually several tens of milliseconds. For Scenario 3, the duration during which the charging voltage value is zero is usually at the nanosecond level. On this basis, the embodiments of the present application determine which of the above three scenarios the zero charging voltage value belongs to based on the duration during which the charging voltage value is zero.

[0036] In this embodiment, it can be understood that, before the above S1200, the charging method provided by the embodiments of the present application further includes: a step of detecting whether the charging voltage value is zero.

[0037] S1300. When the duration is within the preset duration range, control the charger connected to the electronic device to reduce the current power supply voltage value, and / or control the overvoltage protection circuit in the electronic device to increase the current voltage threshold value.

[0038] In this embodiment, the preset duration range is the range of the duration required for the overvoltage protection circuit to restore the charging circuit between the electronic device and the charger from being disconnected to being conductive. This preset duration range can be set according to experience or determined through experiments.

[0039] In one embodiment, when the preset duration range is determined through experiments, the specific process of this experiment can be: select the longest duration T1 required for the test overvoltage protection circuit to restore from the disconnected circuit to the conductive circuit, and select the shortest duration T2 required for the test overvoltage protection circuit to restore from the disconnected circuit to the conductive circuit. At the same time, considering the setting of the margin △T, set the preset duration range as [T2 + △T, T1 + △T]. Among them, the margin △T can be set according to experience. The test overvoltage protection circuit is an overvoltage protection circuit with a voltage threshold value similar to that of the overvoltage protection circuit in this embodiment.

[0040] In this embodiment, it can be understood that, before the above S1300, the charging method provided by the embodiments of the present application further includes: a step of detecting whether the duration is within the preset duration range.

[0041] In this embodiment, the charger can automatically adjust the output voltage value under the control of the electronic device to output power supply voltages of multiple gears. And, the overvoltage protection circuit can adjust the voltage threshold value within a certain range under the control of the electronic device.

[0042] In this embodiment, when the duration is within the preset duration range, it is explained that the charging voltage value being zero is caused by the above-mentioned Scenario 2. On this basis, the charger is controlled to reduce the current power supply voltage value. In this way, when the power grid is unstable, the possibility that the power supply voltage value provided by the charger to the electronic device exceeds the OVP threshold value is reduced, that is, the possibility that the charging path between the charger and the electronic device is frequently disconnected is reduced.

[0043] Among them, controlling the charger to reduce the current power supply voltage value can specifically be to reduce the current power supply voltage value of the charger to the power supply voltage value of the next lower gear, or to reduce the current power supply voltage value of the charger to the lowest gear power supply voltage value, etc. On this basis, it can be known that controlling the charger connected to the electronic device to reduce the current power supply voltage value in the above S1300 can specifically be:

[0044] Controlling the charger connected to the electronic device to reduce the current power supply voltage value to the power supply voltage value of the next lower gear.

[0045] In addition, the overvoltage protection circuit in the electronic device can also be controlled to increase the current voltage threshold value. For example, the current voltage threshold value of the overvoltage protection circuit is increased to the voltage threshold value of the next higher gear. In this way, when the power grid is unstable, the possibility that the power supply voltage value provided by the charger to the electronic device exceeds the OVP threshold value is reduced, that is, the possibility that the charging path between the charger and the electronic device is frequently disconnected is reduced.

[0046] Corresponding to the above S1300, when the duration is not within the preset duration range, it is determined that the electronic device is in the above-mentioned Scenario 1 or Scenario 2. At this time, the electronic device can do nothing.

[0047] In the embodiment of the present application, a charging method is provided. This method is applied to an electronic device and includes: obtaining the charging voltage value of the electronic device; when the charging voltage value is zero, monitoring the duration for which the charging voltage value is zero; when the duration is within the preset duration range, controlling the charger connected to the electronic device to reduce the current power supply voltage value, and / or controlling the overvoltage protection circuit in the electronic device to increase the current voltage threshold value. Through this method, when the power grid is unstable, the possibility that the charging path between the charger and the mobile phone is frequently disconnected can be reduced. On the one hand, this can reduce the possibility that the charging icon on the electronic device frequently disappears, thereby improving the user's experience of using the device. On the other hand, it can reduce the possibility that the charging path between the charger and the mobile phone is continuously and frequently disconnected and then the charging path between the charger and the mobile phone no longer resumes, which reduces the possibility that the charging icon no longer resumes, thereby reducing the possibility that the user mistakenly believes that the mobile phone is damaged, and further improving the user's experience of using the device.

[0048] In one embodiment, corresponding to S1200 above, the charging method provided by the embodiments of the present application further includes the following S1410:

[0049] S1400. When the charging voltage value is not zero, control the current power supply voltage value of the charger to remain unchanged.

[0050] In this embodiment, when the charging voltage value is not zero, it indicates that the charger can normally charge the battery of the electronic device. At this time, the current power supply voltage value of the charger can be controlled to remain unchanged.

[0051] In another embodiment, corresponding to S1200 above, the charging method provided by the embodiments of the present application further includes the following S1420:

[0052] S1420. When the charging voltage is not zero, control the charger to increase the current power supply voltage value.

[0053] In this embodiment, when the charging voltage value is not zero, it indicates that the charger can normally charge the battery of the electronic device. At this time, the current power supply voltage value of the charger can be controlled to increase, for example, increasing the current power supply voltage value of the charger to the power supply voltage value of the next higher gear, or increasing the current power supply voltage value of the charger to the power supply voltage value of the highest gear, etc. In this way, the charging speed of the electronic device can be increased.

[0054] In one embodiment, after S1300 in the charging method provided by the embodiments of the present application, it further includes the following S1500:

[0055] S1500. Repeatedly obtain the charging voltage value of the electronic device.

[0056] In this embodiment, after controlling the charger connected to the electronic device to reduce the current power supply voltage value, the charging voltage value of the battery of the electronic device is obtained again to repeatedly execute S1100 - S1300 above. In this way, the problem that the power supply voltage value provided by the charger to the electronic device exceeds the OVP threshold value can be directly avoided.

[0057] In one embodiment of the present application, the specific implementation of controlling the charger connected to the electronic device to reduce the current power supply voltage value in S1300 when the continuous duration is within the preset duration range can be as follows S1310:

[0058] S1310. When the continuous duration is within the preset duration range and the current power supply voltage value is greater than the first voltage value of the charger, control the charger connected to the electronic device to reduce the current power supply voltage value.

[0059] In this embodiment, the first voltage value can be the minimum power supply voltage value of the charger. When the duration is within the preset duration range and the current power supply voltage value is greater than the first voltage value of the charger, it indicates that the current power supply voltage value can still be reduced. At this time, control the charger connected to the electronic device to reduce the current power supply voltage value.

[0060] Corresponding to S1310 above, when the duration is within the preset duration range and the current power supply voltage value is equal to the first voltage value of the charger, it indicates that the current power supply voltage value cannot be reduced. At this time, control the charger connected to the electronic device to output a prompt message to prompt the user that the charging voltage value is caused by Scenario 2 above. This can prevent the user from mistakenly thinking that the electronic device is damaged, thereby improving the user's experience of using the device.

[0061] In an embodiment of the present application, the specific implementation of controlling the overvoltage protection circuit in the electronic device in S1300 to increase the current voltage threshold value can be as follows in S1320:

[0062] S1320: When the current voltage threshold value is less than the target voltage threshold value, control the overvoltage protection circuit in the electronic device to increase the current voltage threshold value.

[0063] Among them, the target voltage threshold value is the voltage value of the maximum voltage that the battery can withstand.

[0064] In this embodiment, when the current voltage threshold value is less than the target voltage threshold value, it indicates that the current voltage threshold value can still be increased. At this time, control the overvoltage protection circuit in the electronic device to increase the current voltage threshold value.

[0065] Correspondingly, when the current voltage threshold value is equal to the target voltage threshold value, it indicates that the current voltage threshold value cannot be increased. At this time, control the charger connected to the electronic device to output a prompt message to prompt the user that the charging voltage value is zero is caused by Scenario 2 above. This can prevent the user from mistakenly thinking that the electronic device is damaged, thereby improving the user's experience of using the device.

[0066] Combining the above content, in an embodiment, as Figure 2 shown, the charging method provided by the embodiment of the present application includes the following S2100 - S2600:

[0067] S2100: Obtain the charging voltage value of the electronic device, and then execute S2200 below.

[0068] S2200: Detect whether the charging voltage value is zero. If it is, execute S2300 below; if not, execute S2400 below;

[0069] S2300. Monitor the duration for which the charging voltage value is zero, and then execute S2500 below.

[0070] S2400. Control the charger to maintain the current power supply voltage value and end.

[0071] S2500. Detect whether the duration is within a preset duration range. If so, execute S2600 below; if not, end.

[0072] S2600. Control the charger connected to the electronic device to reduce the current power supply voltage value to the power supply voltage value of the next level, and then execute S2100 above.
