It is to be understood that the data so used are interchangeable under appropriate circumstances so that the embodiments of the disclosure described herein can be practiced in sequences other than those illustrated or described herein. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with aspects of the disclosure as detailed in the appended claims.

Figure 1 is a flow chart of a charging method according to an exemplary embodiment. As shown in Figure 1, the charging method according to the embodiment of the present disclosure includes the following steps.

S101. In response to the connection between the charger and the charging interface of the electronic device, determine the first protocol as the charging protocol of the electronic device.

It should be noted that the charging method in the embodiment of the present disclosure is executed by an electronic device. Electronic devices include mobile phones, notebooks, desktop computers, vehicle-mounted terminals, smart home appliances, wearable devices, etc. Among them, wearable devices can include wrist-worn devices (such as smart watches, smart bracelets), head-mounted devices, foot-worn devices, etc. The charging method of the embodiment of the present disclosure can be performed by the charging device of the embodiment of the present disclosure. The charging device of the embodiment of the present disclosure can be configured in any electronic device to perform the charging method of the embodiment of the present disclosure.

It should be noted that the charging interfaces and chargers of electronic devices all support the first protocol. When both the charging interface and the charger of the electronic device support the first protocol, the default first protocol is the charging protocol of the electronic device.

It should be noted that there are no excessive restrictions on the charging interface and the first protocol of electronic devices. The first protocol may be a fast charging protocol or a slow charging protocol.

For example, the charging interface of electronic equipment is a USB (Universal Serial Bus, Universal Serial Bus) Type-C interface. Among them, the USB Type-C interface is smaller than the USB Type-A interface and USB Type-B interface. Type-A interface, USB Type-B interface, and USB Type-C interface are all USB interfaces.

For example, the first protocol is the USB PD (Power Delivery) protocol, hereinafter referred to as the PD protocol. Among them, the PD protocol is a fast charging protocol based on the USB interface.

S102. Obtain the impedance value between the first pin and the second pin of the charging interface of the electronic device.

It can be understood that under normal circumstances, there is an open circuit between the first pin and the second pin, that is, the impedance value between the first pin and the second pin is infinite. However, if the charging interface of the electronic device is exposed, Impurities, water vapor and other substances can easily enter the charging interface of electronic equipment, causing a short circuit between the first pin and the second pin. That is, the impedance value between the first pin and the second pin can be measured or calculated.

It should be noted that the first pin and the second pin are both pins in the charging interface of the electronic device, and the first pin and the second pin are different pins. There are no excessive restrictions on the first pin and the second pin. For example, the first pin is the power supply pin and the second pin is the communication pin. Among them, the power supply pin may include a VBUS pin, and the communication pin may include a CC (Configuration Channel, configuration channel) pin.

It should be noted that obtaining the impedance value between the first pin and the second pin of the charging interface of the electronic device can be achieved by using any method of obtaining the impedance value in related technologies, and there are no excessive limitations here.

In one implementation, as shown in Figure 2, the electronic device includes a PMIC (Power Management Integrated Circuit). The PMIC includes a voltage acquisition circuit that enables a pull-down resistor Rd and a second pin. The first pin is connected to The first end of the charger is connected, the second pin is connected to the second end of the charger, the first end of the enable pull-down resistor Rd, the voltage acquisition circuit of the second pin, and the second end of the enable pull-down resistor Rd Ground.

If there is an open circuit between the first pin and the second pin, that is, the impedance value R between the first pin and the second pin is infinite, and the voltage of the second pin is zero.

If the first pin and the second pin are short-circuited, the voltage _Vo of the first pin is divided by the impedance value R and the enable pull-down resistor Rd. The calculation process of the impedance value R is as follows:

R = (V _o -Vcc)/(Vcc/Rd)

Among them, _Vo is the voltage of the first pin and the output voltage of the charger, and Vcc is the voltage of the second pin.

For example, taking V _o =5V (volt), Vcc =3V, Rd =5.1KΩ (kiloohm) as an example, the calculation process of the impedance value R is as follows:

R = (5-3)/(3/5.1)= 3.4KΩ

In one embodiment, after obtaining the impedance value between the first pin and the second pin of the charging interface of the electronic device, it also includes generating reminder information indicating that there is a short circuit fault in the charging interface of the electronic device, and promptly The user is informed that there is a short circuit fault in the charging interface of the electronic device, so that the user can repair or replace the charging interface of the electronic device in time, which improves the charging safety of the electronic device.

After the impedance value is obtained, the above mapping relationship can be queried based on the impedance value, and the charging strategy mapped by the impedance value can be determined as the charging strategy of the electronic device. . It can be understood that different impedance values can map to different charging strategies, or they can map to the same charging strategy.

In one implementation, controlling the charging of the electronic device based on the impedance value includes determining the charging state of the charger based on the impedance value, and controlling the charging of the electronic device based on the charging state of the charger. Therefore, in this method, the charging state of the charger can be determined based on the impedance value, and the charging of the electronic device can be controlled taking into account the charging state of the charger, thereby improving the charging reliability of the electronic device.

It should be noted that the charging status of the charger is not too limited. For example, taking the first protocol as the PD protocol as an example, the charging status of the charger may include PD protocol recognition success, PD protocol recognition failure, and PD protocol communication failure. , PD protocol communication is successful, charging voltage request is successful, charging voltage request is failed, voltage boost request is successful, voltage boost request fails, whether charging interruption occurs (such as hard reset), whether charging is normal, whether short circuit heating occurs, etc.

For example, the mapping relationship between the impedance value and the charging state of the charger can be established in advance. After obtaining the impedance value, the above mapping relationship can be queried based on the impedance value, and the charging state mapped by the impedance value can be determined as the charging state of the charger. . It can be understood that different impedance values can map different charging states or the same charging state.

In one implementation, the mapping relationship between the impedance value R, the charging state of the charger, and user experience is as shown in Table 1.

Table 1 Mapping relationship between impedance value R, charger’s charging status, and user experience

In some examples, controlling the charging of the electronic device based on the charging state of the charger includes determining the charging strategy of the electronic device based on the charging state of the charger, and controlling the charging of the electronic device according to the charging strategy of the electronic device.

For example, a mapping relationship between the charging status of the charger and the charging strategy of the electronic device can be established in advance. After obtaining the charging status of the charger, the above mapping relationship can be queried based on the charging status of the charger, and the charging status of the charger can be queried. The charging strategy of the state map is determined as the charging strategy of the electronic device. It can be understood that the charging status of different chargers can be mapped to different charging strategies, or the same charging strategy can be mapped.

In the charging method provided by the embodiment of the present disclosure, in response to the connection between the charger and the charging interface of the electronic device, the first protocol is determined to be the charging protocol of the electronic device, and one of the first pin and the second pin of the charging interface of the electronic device is obtained. The impedance value between the two devices controls the charging of the electronic device based on the impedance value. Therefore, when there is a short circuit between the first pin and the second pin of the charging interface of the electronic device, the impedance value between the first pin and the second pin can be taken into account to control the charging of the electronic device. It avoids problems such as intermittent charging and charging failure of electronic equipment caused by short-circuit faults, and improves the charging continuity and reliability of electronic equipment.

It should be noted that the failure of the first protocol communication between the charger and the electronic device is the first charging state of the charger. It can be understood that if the first protocol communication between the charger and the electronic device fails, and the charging of the electronic device cannot be controlled according to the first protocol, the charging of the electronic device can be controlled to stop.

For example, continuing to take Table 1 as an example, the first protocol is the PD protocol. If the impedance value R<35KΩ, it can be determined that the charging status of the charger is that the PD protocol communication between the charger and the electronic device has failed, and the control stops charging the electronic device.

It should be noted that the charger fails to request the charging voltage to be the first voltage, and the charger has a charging interruption, which is the second charging state of the charger. It can be understood that if the charger fails to request the charging voltage to be the first voltage and the charger interrupts charging, in order to avoid the problem of intermittent charging and charging failure of the electronic device, the charging voltage of the electronic device can be updated to the second voltage. That is, the charging voltage of the electronic device is updated to a fixed charging voltage, and the charging of the electronic device is controlled according to the fixed charging voltage.

The first voltage and the second voltage are within the value range of the charging voltage configured by the first protocol, and the second voltage is smaller than the first voltage.

For example, continue to use Table 1 as an example. The first protocol is the PD protocol, the first voltage is 9V, and the second voltage is 5V. If 35KΩ≤impedance value R<77KΩ, it can be determined that the charger’s charging status is the charger’s requested charging voltage. If it fails to 9V and the charger interrupts charging, update the charging voltage of the electronic device to 5V and control the charging of the electronic device according to the 5V charging voltage.

S308: Control charging of the electronic device according to the first voltage.

It should be noted that the charger's request for the charging voltage to be the first voltage is successful, and the charger's request for the charging voltage to be the third voltage fails, and the charger does not have a charging interruption, which is the third charging state of the charger. It can be understood that if the charger successfully requests the charging voltage to be the first voltage, but fails to request the charging voltage to be the third voltage, and the charger does not interrupt charging, in order to avoid the problem of charging failure of the electronic device, the electronic device can be The charging voltage is updated to the first voltage, that is, the charging voltage of the electronic device is updated to a fixed charging voltage, and the charging of the electronic device is controlled according to the fixed charging voltage.

Wherein, the first voltage and the third voltage are within the value range of the charging voltage configured by the first protocol, and the first voltage is smaller than the third voltage. Neither the first voltage nor the third voltage is too limited. For example, the first voltage is 9V and the third voltage is 10V.

For example, continuing to use Table 1 as an example, the first protocol is the PD protocol, the first voltage is 9V, and the third voltage is 10V. If 77KΩ≤impedance value R<82KΩ, it can be determined that the charger’s charging status is the charger’s requested charging voltage. If it is 9V successfully, and the charger fails to request a charging voltage of 10V, and the charger does not interrupt charging, the charging voltage of the electronic device is updated to 9V, and the charging of the electronic device is controlled according to the 9V charging voltage.

S309: If the charger successfully requests the charging voltage to be the first voltage, and the charger fails to request the charging voltage to be the third voltage, and the charger interrupts charging, update the charging protocol of the electronic device from the first protocol to the second protocol.

S310: Control charging of the electronic device according to the second protocol.

It should be noted that the charger's request for the charging voltage to be the first voltage is successful, and the charger's request for the charging voltage to be the third voltage fails, and the charger's charging interruption is the fourth charging state of the charger. It can be understood that if the charger successfully requests the charging voltage to be the first voltage, and the charger fails to request the charging voltage to be the third voltage, and the charger interrupts charging, in order to avoid the problem of intermittent charging and charging failure of the electronic device, you can The charging protocol of the electronic device is updated from the first protocol to the second protocol, and the charging of the electronic device is controlled according to the second protocol.

For example, continue to use Table 1 as an example. The first protocol is the PD protocol, the second protocol is the QC protocol, the first voltage is 9V, and the third voltage is 10V. If 82KΩ≤impedance value R<166KΩ, the charger can be determined. The status is that the charger's request for a charging voltage of 9V is successful, and the charger's request for a charging voltage of 10V fails, and the charger has a charging interruption.

It can be understood that if the first protocol communication between the charger and the electronic device is successful, and the charger's requested charging voltage does not appear abnormal, and the temperature of the charging interface of the electronic device is greater than the set threshold, it means that the charger can The electronic device is charged normally, and there is only a problem of short circuit and heating. The electronic device can continue to be charged according to the first protocol.

It should be noted that there are no excessive restrictions on the set threshold.

For example, continuing to use Table 1 as an example, the first protocol is the PD protocol. If 166 KΩ ≤ impedance value R, it can be determined that the charging status of the charger is that the PD protocol communication between the charger and the electronic device is successful, and the charger requests charging If there is no abnormality in the voltage, and the temperature of the charging interface of the electronic device is greater than the set threshold, the electronic device is controlled to be charged according to the PD protocol.

In one embodiment, according to the first protocol, the process of controlling the charging of the electronic device also includes detecting the changing trend and changing speed of the temperature of the charging interface of the electronic device. If the changing trend of the temperature of the charging interface of the electronic device is an upward trend, and the change rate of the temperature of the charging interface of the electronic device is greater than or equal to the set threshold, indicating that the temperature of the charging interface of the electronic device rises rapidly, a reminder message is generated to indicate that there is a short circuit fault in the charging interface of the electronic device, And/or, generate a reminder message indicating that the temperature of the charging interface of the electronic device rises rapidly.

In this embodiment, the charging state of the charger includes five charging states. In addition to the above five charging states, the charging state of the charger may also include other implementations, which are not too limited here.

The charging method provided by the embodiments of the present disclosure can pre-divide the charging status of the charger into five states, and pre-configure the corresponding charging strategy of the electronic device for each state to control the charging of the electronic device and avoid short circuits. The fault causes problems such as intermittent charging and charging failure of electronic equipment, which improves the charging continuity and reliability of electronic equipment.
