Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
In the quick charge technology, if the impedance of the charging wire increases, the quick charge is liable to fail to work normally, and the phenomenon of intermittent charging (continuous charging→breaking→charging→breaking) occurs.
At present, when the charger cannot normally charge the electronic equipment quickly, measures are not taken, and the electronic equipment is charged in the abnormal quick charging mode, or is replaced by the electronic equipment which is charged in the non-quick charging mode. For example, no matter a smart phone supporting 30W/45W or 90W fast charging, no measures are taken when charging is interrupted, and there are other ways to directly prohibit PD (Power Delivery) 3.0.0 with PPS (programmable power supply) protocol after five or six times of charging interruption, that is, prohibit fast charging, and reduce the original 45W fast charging power to 15W for slow charging. However, the applicant has found that when the device cannot be normally and rapidly charged based on the original fast charging power due to an increase in the charging line impedance of the fast charging charger, the fast charging charger may still be capable of performing the fast charging at a lower power value than the original fast charging power. For example, a certain fast charging charger has a charging interruption phenomenon under the original 45w fast charging power due to the increase of the charging line impedance, but the fast charging charger can still work at 40w, namely, the equipment can still be charged fast under the power of 40w, and the method of the samsunote 10+ is to directly dry the fast charging as long as the fast charging is not carried out normally at 45w, and the method is replaced by a slow charging method, so that the fast charging advantage of the fast charging charger cannot be effectively utilized, and customer complaints are easily caused.
In view of this, the present application provides a charging processing method and an electronic device, so as to provide a better solution for the fast charging abnormality, and to maintain the fast charging characteristic of the fast charging charger to a high extent when the fast charging abnormality is caused by the increase of the impedance of the charging line.
Referring to fig. 1, a flowchart of a charging processing method according to an embodiment of the present application is provided, and the method may be applied to, but not limited to, an electronic device supporting a fast charging function, such as a smart phone, a tablet computer, a smart bracelet, a personal digital assistant, and the like.
As shown in fig. 1, the charging processing method of the present embodiment includes the following processing steps:
The fast charging device may be, but is not limited to, a portable or vehicle-mounted fast charger.
The determining whether the quick charging device performs the quick charging on the electronic device based on the first charging power is abnormal or not may specifically be determining whether the quick charging on the electronic device based on the first charging power performed by the quick charging device performs the charging intermittent phenomenon of charging-breaking-charging-breaking.
The first charging power is an original fast charging power based on the fast charging device when the charging line impedance of the fast charging device is normal (not increased) and is generally a maximum fast charging power allowed or born by the charging line based on the original impedance (the impedance when leaving the factory).
In one embodiment, during the fast charging of the electronic device by the fast charging device based on the first charging power, it may be determined whether communication between the electronic device and the fast charging device based on a predetermined fast charging protocol fails, if the communication fails, it is determined that the fast charging of the fast charging device is abnormal, and if not, it is determined that the fast charging is not abnormal.
The predetermined fast-fill protocol may be, but is not limited to, the PD3.0 with PPS communication protocol.
Specifically, in the process that the quick charging device carries out quick charging on the electronic equipment based on the first charging power, the electronic equipment continuously carries out two-way communication with the quick charging device based on a communication protocol such as PD3.0 with PPS, wherein state information such as output voltage, output current and/or temperature of the quick charging device is continuously obtained based on the communication electronic equipment, and an instruction is sent to the quick charging device to dynamically indicate the output voltage/current required by the current charging of the quick charging device according to a strategy such as whether overcurrent, overvoltage and/or overtemperature and according to the first charging power based on the strategy, so that the phenomenon of overcurrent, overvoltage and/or overtemperature cannot occur, and the power of the quick charging device in the whole quick charging process based on the communication is ensured not to exceed the first charging power. If the impedance of the charging wire increases and at the same time charging with a large charging current results in communication failure/interruption of the PPS communication at the PD3.0, then when the charging current is reduced, communication can be resumed, thereby causing a charge interruption phenomenon.
Based on the above-mentioned quick charging process of the quick charging device, the embodiment can determine whether the quick charging of the quick charging device is abnormal by detecting whether the communication between the electronic device and the quick charging device based on the predetermined quick charging protocol (such as PD3.0 with PPS communication protocol) fails.
In another embodiment, whether the quick charging device has a quick charging abnormality may be determined by detecting whether the actual impedance of the charging wire of the quick charging device is abnormal, where if the impedance of the charging wire increases and increases to a value that is likely to cause the charging abnormality, it may be determined that the quick charging of the quick charging device has an abnormality.
In this embodiment, specifically, when the quick charging device is connected to the electronic device through the charging wire, in response to detecting that the quick charging device is connected to the electronic device, the impedance of the charging wire is detected and obtained, and whether the impedance of the charging wire exceeds a set threshold value is determined, if the impedance exceeds the threshold value, it is determined that the quick charging of the quick charging device is abnormal.
Preferably, the threshold value may be set as: and determining the lowest impedance value corresponding to the charging line, which can cause abnormal charging of the quick charging device according to experience, test and/or corresponding calculation.
And 102, if the quick charge is abnormal, determining a second charge power according to the impedance when the impedance of the charge wire does not meet the impedance condition.
In this embodiment, the impedance condition may be specifically set as: the impedance of the charging wire of the quick charging device does not exceed the threshold value.
There are many factors that cause a rapid charging abnormality of a rapid charging device, including but not limited to any one or more of the following:
1) The hardware components of the charger are damaged;
2) Communication protocol abnormality;
3) The charging wire impedance increases to a threshold value that would cause a rapid charging anomaly;
for example, the charging wire impedance increases during use due to a small probability of failure event (e.g., poor welding quality of the connection point) at the time of factory production, or increases during use due to poor material or stealth and material reduction (e.g., mountain-stand charging wire), or increases during long-term use due to influence of welding caused by multiple bending and pulling, or the like.
The embodiment of the present application aims to solve the problem of the quick charge abnormality caused by the abnormality (increase in impedance) of the charging line, and therefore, in the case of determining the quick charge abnormality of the quick charge device, it is necessary to determine whether or not the cause of the quick charge abnormality of the quick charge device is the abnormality of the charging line thereof (i.e., the above-described impedance condition is not satisfied).
Specifically, in the embodiment of determining whether the quick charge abnormality exists by detecting the communication condition during the quick charge, when it is determined that the quick charge abnormality exists, the impedance of the charging wire of the quick charge device may be further detected and obtained, and whether the impedance of the charging wire exceeds a threshold value may be determined, if the impedance exceeds the threshold value, it may be determined that the impedance of the charging wire does not satisfy the impedance condition, and in this case, it may be further determined that the cause of the quick charge abnormality is the impedance abnormality of the charging wire, otherwise, the cause of the quick charge abnormality is other factors.
In the embodiment of determining whether the quick charge is abnormal according to the actual impedance of the charging wire, once it is determined that the quick charge is abnormal, the reason for the quick charge abnormality may be directly determined as the charging wire impedance abnormality.
Under the condition that the quick charge is determined to be abnormal and the impedance of the charging wire does not meet the impedance condition (namely, the reason of the quick charge abnormality is the impedance abnormality of the charging wire), an adaptive second charging power which can enable the quick charge to be free of the abnormality can be further determined according to the detected and obtained impedance of the charging wire.
The second charging power is not larger than the maximum charging power which enables the rapid charging device to charge the electronic equipment without abnormality, and the second charging power and the maximum charging power meet the approaching condition; the maximum charging power is smaller than the first charging power.
The above approach condition may be set as: the absolute value of the difference between the second charging power and the maximum charging power is smaller than a preset threshold value. Based on the proximity condition, the second charging power may be specifically the above maximum charging power, or a power value smaller than the above maximum charging power and having a difference absolute value from the maximum charging power smaller than a predetermined threshold. In practice, it may be preferable to set the second charging power to the maximum charging power described above.
The applicant has found that the maximum allowable/sustained fast charge power is different when the charge lines with different impedances or the same charge line corresponds to different impedances due to impedance change (e.g. increase), and that the abnormal charge occurs if the charge power exceeds the allowable/sustained maximum fast charge power. Based on this feature, in this embodiment, a set of correspondence between different impedance information of the charging wire and different maximum charging power is prepared in advance.
Based on this, when determining the second charging power according to the detected and acquired charging line impedance, specifically, the maximum charging power corresponding to the detected charging line impedance may be acquired from a set of correspondence relationships between different impedance information and different maximum charging powers, and the second charging power may be determined according to the acquired maximum charging power and the above-mentioned proximity condition.
For example, assuming that the first charging power (the original fast charging power) corresponding to the fast charging device is 45w, when the maximum allowable fast charging power decreases from 45w to 40w due to the increase of the charging line impedance, any value, such as 38w, 39w, 40w, with an absolute value of the difference from 40w being smaller than the threshold (e.g. 3 w), may be specifically determined as the second charging power based on which the subsequent fast charging is required.
And step 103, controlling the quick charging device to charge the electronic equipment based on the second charging power.
Wherein, based on the second charging power, the fast charging device is controlled to charge the electronic device, which can be realized as follows: controlling the quick charging device to charge the electronic equipment at a power value not exceeding the second charging power
Specifically, during the charging process, the electronic device may continuously send an output voltage/current instruction to the quick charging device through a quick charging protocol (such as PD3.0 with PPS) according to a control policy such as over-current/over-voltage/over-temperature control and the determined second charging power, and the quick charging device charges the electronic device with the output voltage/current indicated by the received instruction, so as to ensure that no over-current, over-voltage and/or over-temperature phenomena occur in the whole quick charging process, and the power of the quick charging device does not exceed the second charging power.
It is easy to understand that, because the second charging power does not exceed the maximum charging power corresponding to the current impedance of the charging wire and capable of enabling the rapid charging device to charge the electronic equipment without abnormality, the second charging power is safe power adapted to the current impedance of the charging wire, and based on the second charging power, abnormal phenomena such as intermittent charging and the like in the charging process of the rapid charging device are not caused; in addition, since the second charging power and the maximum charging power meet the approaching condition, the quick charging advantage of the quick charging device can be exerted to a greater extent or even to the maximum extent (for example, the second charging power is equal to the maximum charging power), and when the quick charging is abnormal due to the increase of the impedance of the charging line, the electronic equipment can be continuously quickly charged based on the reduced adaptive charging power.
According to the charge processing method, when the quick charge device is abnormal due to the fact that the impedance of the charging wire is increased, the charge power of the quick charge device can be reduced, and particularly the first charge power based on the abnormal quick charge is reduced to the second charge power according to the actual impedance of the charging wire, so that the problem of the abnormal quick charge is solved.
Optionally, in an embodiment, when detecting the acquired charging line impedance, for example, detecting the acquired charging line impedance in response to detecting that the quick charging device is connected to the electronic device, or detecting the acquired charging line impedance when determining that there is an abnormality in the quick charging, referring to fig. 2, the detection of the charging line impedance may be specifically implemented through the following processing procedure:
Alternatively, referring to fig. 3, when the impedance of the charging wire needs to be detected and obtained, the electronic device may specifically prohibit the quick charging device from currently charging the electronic device, and control the output voltage of the quick charging device to a fixed voltage, that is, the first voltage.
Specifically, the impedance of the charging wire may be calculated based on the following calculation formula (1):
Vadapter＝Vphone1+I*R (1)
wherein Vadapter represents the output voltage of the quick charge device, i.e., the first voltage, vphone1 represents the second voltage at the electronic device, I represents the current of the charging wire, and R represents the impedance of the charging wire.
In practice, to ensure the reliability of the detected impedance of the charging line, it may be preferable to obtain a plurality of impedance measurements of the charging line by performing the above-described process a plurality of times, and take the maximum value thereof as the impedance of the charging line.
Now, an example is described:
for example, in the case of controlling the output voltage of the quick charging device to the first voltage Vadapter, the electronic device is first controlled to charge with a relatively small current and simultaneously test the device side voltage Vphone1 and the charging line current I1 at that time, and then the electronic device is controlled to charge with a relatively large current and simultaneously test the device side voltage Vphone2 and the charging line current I2 at that time, on the basis of which two impedance measurement values of the charging line are obtained based on the following calculation formulas (2) - (3), respectively, and the maximum value thereof is taken as the impedance of the charging line:
Vadapter＝Vphone1+I1*R (2)
Vadapter＝Vphone2+I2*R (3)。
the processing procedure of detecting and acquiring the charging wire impedance is not perceived by the device user, so that the charging wire impedance can be acquired under the condition that the user does not perceive, and a basis is provided for subsequent quick-charging abnormal processing.
Optionally, in an embodiment, referring to the flowchart of the charging processing method shown in fig. 4, after step 103, the charging processing method disclosed in the present application may further include:
In the case that the quick charge is abnormal and the impedance of the charging wire satisfies the impedance condition, that is, the reason for the quick charge abnormality is other factors than the impedance abnormality of the charging wire, the embodiment resets the charging flow of the electronic device by the quick charge device.
Specifically, when the quick charging device is reset to perform the charging process on the electronic device, the quick charging device may be controlled to charge the electronic device with a third voltage (output voltage) at first, and then the quick charging device is controlled to gradually increase the voltage when the electronic device is charged until the quick charging device is reset to perform the quick charging on the electronic device based on the first charging power.
Optionally, in an embodiment, referring to the flowchart of the charging processing method shown in fig. 5, after step 103, the charging processing method disclosed in the present application may further include:
Specifically, when the electronic device performs quick charging based on the second charging power by automatically adapting to the charging line impedance according to the situation that the quick charging is abnormal due to the abnormal charging line impedance, the electronic device may also generate and display corresponding prompt information to inform the user of the abnormal charging line, for example, in the form of voice and/or text information (which may also be combined with corresponding light auxiliary effects), prompt a user to replace the charging line or the abnormal charging line, and prompt a user to replace the charging line.
Based on the embodiment, when the quick charging is abnormal due to the abnormal impedance of the charging wire, the user can be informed of the replacement of the charging wire in time, the user experience is improved, and the customer complaint probability is effectively reduced.
