Detailed Description
In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the foregoing figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the disclosure described herein may be capable of operation in sequences other than those illustrated or described herein. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
The data acquisition, storage, use, processing and the like in the technical scheme of the present disclosure all conform to the relevant regulations of the national laws and regulations.
Fig. 1 is a flowchart illustrating a charging method according to an exemplary embodiment, and as shown in fig. 1, the charging method of the embodiment of the present disclosure includes the following steps.
S101, determining that the first protocol is a charging protocol of the electronic equipment in response to connection of the charger and a charging interface of the electronic equipment.
It should be noted that, the main implementation body of the charging method in the embodiment of the disclosure is an electronic device, and the electronic device includes a mobile phone, a notebook computer, a desktop computer, a vehicle-mounted terminal, an intelligent household appliance, a wearable device, and the like. The wearable device may include, among other things, a wrist-worn device (such as a smart watch, a smart bracelet), a head-worn device, a foot-worn device, and the like. The charging method of the embodiment of the present disclosure may be performed by the charging apparatus of the embodiment of the present disclosure, and the charging apparatus of the embodiment of the present disclosure may 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 interface and the charger of the electronic device both support the first protocol. Under the condition that the charging interface and the charger of the electronic equipment support the first protocol, the first protocol is defaulted to be the charging protocol of the electronic equipment.
It should be noted that, neither the charging interface nor the first protocol of the electronic device is excessively limited. The first protocol may be a fast charge protocol or a slow charge protocol.
For example, the charging interface of the electronic device is an USB (Universal Serial Bus ) Type-C interface, where the USB Type-C interface is smaller than the USB Type-a interface and the USB Type-B interface, and the USB Type-a interface, the USB Type-B interface and the USB Type-C interface are all USB interfaces.
For example, the first protocol is a USB PD (Power Delivery) protocol, hereinafter abbreviated as PD protocol. The PD protocol is a fast charging protocol based on a USB interface.
S102, obtaining an impedance value between a first pin and a second pin of a charging interface of the electronic device.
It will be appreciated that, in the normal case, an open circuit exists between the first pin and the second pin, i.e. 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, moisture, etc. easily enter the charging interface of the electronic device, which results in a short circuit between the first pin and the second pin, i.e. 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. The first pin and the second pin are not excessively limited. For example, the first pin is a power supply pin and the second pin is a communication pin. Wherein the power pin may comprise a VBUS pin and the communication pin may comprise a CC (Configuration Channel ) pin.
It should be noted that, the method for obtaining the impedance value between the first pin and the second pin of the charging interface of the electronic device may be implemented by any method for obtaining the impedance value in the related art, which is not limited herein.
In one embodiment, as shown in fig. 2, the electronic device includes a PMIC (Power Management Integrated Circuit ) including a voltage acquisition circuit enabling a pull-down resistor Rd and a second pin, the first pin being connected to a first terminal of the charger, the second pin being connected to a second terminal of the charger, the voltage acquisition circuit enabling the first terminal of the pull-down resistor Rd, the second pin, respectively, and the second terminal of the pull-down resistor Rd being grounded.
If an open circuit exists between the first pin and the second pin, that is, the impedance value R between the first pin and the second pin is infinity, the voltage of the second pin is zero.
If the first pin and the second pin are short-circuited, the voltage V of the first pin o At the impedance value R, the enable pull-down resistor Rd divides the voltage, the impedance value R is calculated as follows:
R =（V o -Vcc）/(Vcc/Rd)
wherein V is o The voltage of the first pin is also the output voltage of the charger, and Vcc is the voltage of the second pin.
For example, in V o For example, =5v (volts), vcc=3v, rd=5.1kΩ (kiloohm), the impedance value R is calculated as follows:
R = (5-3)/(3/5.1)= 3.4KΩ
in one embodiment, after the impedance value between the first pin and the second pin of the charging interface of the electronic device is obtained, the method further comprises generating reminding information for indicating that the charging interface of the electronic device has a short circuit fault, and timely informing a user that the charging interface of the electronic device has the short circuit fault, so that a user can timely repair or replace the charging interface of the electronic device, and charging safety of the electronic device is improved.
In some examples, the method further comprises controlling to display on the electronic device a reminder for indicating that the charging interface of the electronic device has a short circuit fault, and/or sending to the electronic device a reminder for indicating that the charging interface of the electronic device has a short circuit fault.
And S103, controlling the electronic equipment to be charged based on the impedance value.
In one embodiment, controlling charging of the electronic device based on the impedance value includes determining a charging policy of the electronic device based on the impedance value, and controlling charging of the electronic device in accordance with the charging policy of the electronic device.
For example, a mapping relationship between the impedance value and the charging policy of the electronic device may be established in advance, and after the impedance value is obtained, the charging policy mapped by the impedance value may be determined as the charging policy of the electronic device based on the impedance value and the mapping relationship. It will be appreciated that different impedance values may map to different charging strategies, or may map to the same charging strategy.
In one embodiment, controlling charging of the electronic device based on the impedance value includes determining a state of charge of the charger based on the impedance value, and controlling charging of the electronic device based on the state of charge of the charger. Therefore, the method can determine the charging state of the charger based on the impedance value, and control the charging of the electronic equipment by taking the charging state of the charger into consideration, so that the charging reliability of the electronic equipment is improved.
It should be noted that, the charging state of the charger is not limited too much, for example, taking the first protocol as the PD protocol, the charging state of the charger may include success of PD protocol identification, failure of PD protocol communication, success of charging voltage request, failure of charging voltage request, success of voltage boost request, failure of voltage boost request, whether charging interruption (such as hard reset) occurs, whether normal charging is possible, whether short-circuit heating occurs, and so on.
For example, a mapping relationship between the impedance value and the charging state of the charger may be established in advance, and after the impedance value is acquired, the charging state mapped by the impedance value may be determined as the charging state of the charger based on the impedance value and the mapping relationship. It will be appreciated that different impedance values may map to different states of charge, or may map to the same state of charge.
In one embodiment, the mapping relationship among the impedance value R, the charging state of the charger, and the user experience is shown in table 1.
TABLE 1 mapping relationship between impedance value R, charger state of charge, user experience
In some examples, controlling charging of the electronic device based on the state of charge of the charger includes determining a charging policy of the electronic device based on the state of charge of the charger, and controlling charging of the electronic device in accordance with the charging policy of the electronic device.
For example, a mapping relationship between the charging state of the charger and the charging policy of the electronic device may be established in advance, and after the charging state of the charger is obtained, the charging policy mapped by the charging state of the charger may be determined as the charging policy of the electronic device based on the charging state of the charger. It will be appreciated that the states of charge of different chargers may map to different charging strategies, or may map to the same charging strategy.
According to the charging method provided by the embodiment of the disclosure, the charging interface of the charger and the electronic equipment is connected, the first protocol is determined to be the charging protocol of the electronic equipment, the impedance value between the first pin and the second pin of the charging interface of the electronic equipment is obtained, and the electronic equipment is controlled to be charged based on the impedance value. Therefore, when the first pin and the second pin of the charging interface of the electronic equipment are in short circuit, the impedance value between the first pin and the second pin can be considered, the electronic equipment can be controlled to be charged, the problems of intermittent charging, failure charging and the like of the electronic equipment caused by short circuit faults can be avoided, and the charging continuity and reliability of the electronic equipment are improved.
Fig. 3 is a flowchart illustrating a charging method according to another exemplary embodiment, and as shown in fig. 3, the charging method of the embodiment of the present disclosure includes the following steps.
S301, determining that the first protocol is a charging protocol of the electronic device in response to connection of the charger and a charging interface of the electronic device.
S302, obtaining an impedance value between a first pin and a second pin of a charging interface of the electronic device.
S303, determining the charging state of the charger based on the impedance value.
For the relevant content of steps S301-S303, refer to the above embodiments, and are not repeated here.
And S304, if the first protocol communication between the charger and the electronic equipment fails, controlling to stop charging the electronic equipment.
It should be noted that the first protocol communication failure between the charger and the electronic device is the first charging state of the charger. It can be appreciated that if the first protocol communication between the charger and the electronic device fails, and the electronic device cannot be controlled to be charged according to the first protocol, the charging of the electronic device can be controlled to be stopped.
For example, continuing to take table 1 as an example, the first protocol is a PD protocol, if the impedance value R <35kΩ, it may be determined that the charging state of the charger is a PD protocol communication failure between the charger and the electronic device, and control to stop charging the electronic device.
S305, if the charger fails to request the charging voltage to be the first voltage and the charger is interrupted, the charging voltage of the electronic device is updated to be the second voltage.
And S306, controlling the electronic equipment to be charged according to the second voltage.
It should be noted that, the charger fails to request the charging voltage to be the first voltage, and the charger is interrupted to be in the second charging state. It can be understood that if the charger fails to request the charging voltage to be the first voltage and the charger is interrupted, in order to avoid the problems of intermittent charging and failure charging of the electronic device, the charging voltage of the electronic device can be updated to be the second voltage, that is, the charging voltage of the electronic device is updated to be the fixed charging voltage, and the electronic device is controlled to be charged according to the fixed charging voltage.
The first voltage and the second voltage are in the range of the charging voltage configured by the first protocol, and the second voltage is smaller than the first voltage. The first voltage and the second voltage are not limited too much, for example, the first voltage is 9V, and the second voltage is 5V.
For example, taking table 1 as an example, the first protocol is a PD protocol, the first voltage is 9V, the second voltage is 5V, if the impedance value R of 35kΩ is less than or equal to 77kΩ, it may be determined that the charging state of the charger is that the charger requests the charging voltage to be 9V, and the charger fails to charge, the charging voltage of the electronic device is updated to be 5V, and charging of the electronic device is controlled according to the charging voltage of 5V.
S307, if the charger request charging voltage is the first voltage successfully, the charger request charging voltage is the third voltage successfully, and the charger is not interrupted, the charging voltage of the electronic equipment is updated to the first voltage.
And S308, controlling the electronic equipment to be charged according to the first voltage.
It should be noted that, the charger request charging voltage is the first voltage successfully, the charger request charging voltage is the third voltage successfully, and the charger is not in the third charging state of the charger when the charging interruption occurs. It can be understood that if the charger is successful in requesting the charging voltage to be the first voltage, the charger is failed in requesting the charging voltage to be the third voltage, and the charger is not interrupted in charging, in order to avoid the problem of the charging failure of the electronic device, the charging voltage of the electronic device can be updated to be the first voltage, that is, the charging voltage of the electronic device is updated to be the fixed charging voltage, and the electronic device is controlled to be charged according to the fixed charging voltage.
The first voltage and the third voltage are in the range of the charging voltage configured by the first protocol, and the first voltage is smaller than the third voltage. The first voltage and the third voltage are not limited too much, for example, the first voltage is 9V, and the third voltage is 10V.
For example, taking table 1 as an example, the first protocol is a PD protocol, the first voltage is 9V, the third voltage is 10V, if the resistance value R of 77kΩ is less than or equal to 82kΩ, it can be determined that the charging state of the charger is that the charging voltage requested by the charger is 9V, the charging voltage requested by the charger is 10V failure, and the charging interruption does not occur in the charger, the charging voltage of the electronic device is updated to 9V, and the electronic device is controlled to be charged according to the charging voltage of 9V.
S309, if the charger request charging voltage is the first voltage and the charger request charging voltage is the third voltage and the charger fails, the charger is interrupted, and the charging protocol of the electronic device is updated from the first protocol to the second protocol.
And S310, controlling the electronic equipment to be charged according to a second protocol.
It should be noted that, the charger requests the charging voltage to be the first voltage successfully, and the charger requests the charging voltage to be the third voltage successfully, and the charger is in the fourth charging state when the charging is interrupted. It can be understood that if the charger requests the charging voltage to be the first voltage successfully and the charger requests the charging voltage to be the third voltage successfully, and the charger fails to charge, in order to avoid the problems of intermittent charging and failure charging of the electronic device, the charging protocol of the electronic device can be updated from the first protocol to the second protocol, and the electronic device is controlled to be charged according to the second protocol.
The content of the first voltage and the third voltage may be referred to the above embodiments, and will not be described herein.
It should be noted that the second protocol is not limited too much, for example, the second protocol is a USB QC (Quick Charge) protocol, hereinafter referred to as QC protocol.
For example, taking table 1 as an example, the first protocol is PD protocol, the second protocol is QC protocol, the first voltage is 9V, the third voltage is 10V, if 82kΩ is less than or equal to the resistance value R <166kΩ, it can be determined that the charging state of the charger is 9V success when the charger requests the charging voltage, the charger fails to request the charging voltage to be 10V, and the charger fails to charge, the charging protocol of the electronic device is updated from PD protocol to QC protocol, and the electronic device is charged according to the QC protocol.
And S311, if the first protocol communication between the charger and the electronic equipment is successful, the charging voltage requested by the charger is not abnormal, the temperature of a charging interface of the electronic equipment is greater than a set threshold value, and the electronic equipment is controlled to be charged according to the first protocol.
It should be noted that, the first protocol communication between the charger and the electronic device is successful, no abnormality occurs in the charging voltage requested by the charger, and the temperature of the charging interface of the electronic device is greater than the set threshold value to be the fifth charging state of the charger. It can be understood that if the first protocol between the charger and the electronic device is successful, the charging voltage requested by the charger is not abnormal, and the temperature of the charging interface of the electronic device is greater than the set threshold, which indicates that the charger can normally charge the electronic device at this time, only the problem of short circuit and heat generation exists, and the charging of the electronic device can be controlled continuously according to the first protocol.
The set threshold value is not limited too much.
For example, taking table 1 as an example, the first protocol is a PD protocol, if 166K Ω is less than or equal to the impedance value R, it may be determined that the charging state of the charger is successful in PD protocol communication between the charger and the electronic device, no abnormality occurs in the charging voltage requested by the charger, and the temperature of the charging interface of the electronic device is greater than the set threshold, and charging is controlled to be performed on the electronic device according to the PD protocol.
In one embodiment, according to the first protocol, the method further includes detecting a change trend and a change speed of a temperature of a charging interface of the electronic device in a process of charging the electronic device, and if the change trend of the temperature of the charging interface of the electronic device is an ascending trend, and the change speed of the temperature of the charging interface of the electronic device is greater than or equal to a set threshold, the method indicates that the temperature of the charging interface of the electronic device is fast to ascend, generating reminding information for indicating that a short circuit fault exists in the charging interface of the electronic device, and/or generating reminding information for indicating that the temperature of the charging interface of the electronic device is fast to ascend.
In this embodiment, the charging states of the charger include 5 charging states, and the charging states of the charger may include other embodiments besides the 5 charging states described above, which are not limited herein.
According to the charging method provided by the embodiment of the disclosure, the charging state of the charger can be divided into five states in advance, and the charging strategy of the corresponding electronic equipment is configured for each state in advance so as to control the charging of the electronic equipment, so that the problems of intermittent charging, failure charging and the like of the electronic equipment caused by short circuit faults can be avoided, and the charging continuity and reliability of the electronic equipment are improved.
