Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a wireless charging method according to an embodiment of the present invention. As shown in fig. 1, a wireless charging method includes the following steps:
step 101, transmitting end equipment sends rated power information of a charging port to a terminal.
The rated power information of the charging port may include a maximum current threshold of the charging port, that is, a maximum current value allowed to pass through the charging port.
In general, after the transmitting device is connected to the charging port, the terminal may use the transmitting device to perform wireless charging.
Since different charging ports have different power ratings, or, in other words, different charging ports, their maximum current thresholds are also different. Therefore, in this step, when the transmitting end device accesses the charging port, the transmitting end device identifies the type of the charging port to obtain the rated power information of the charging port.
In the step, the rated function power information of the charging port is sent to the terminal through the transmitting terminal device, so that the power detection of the terminal is facilitated according to the rated power information of the charging port in the wireless charging process.
Currently, commonly used charging ports may include, but are not limited to, the following:
a Standard downlink Port (SDP for short), the maximum current threshold of which is, for example, 500 ma;
a Dedicated Charging Port (DCP) with a maximum current threshold of, for example, 1800 ma;
a Charging downlink Port (CDP for short), the maximum current threshold of which is, for example, 1500 ma;
a high voltage Quick Charge (QC) port with a maximum current threshold of, for example, 1670 milliamps.
And 102, reading rated power information of the charging port sent by the transmitting terminal equipment by the terminal.
Step 103, the transmitting terminal device sends charging power information to the terminal.
The charging power information sent by the transmitting end device may include, but is not limited to, a charging voltage value. The charging voltage value may be understood as an output voltage value of the charging port, may also be understood as an input voltage value of the transmitting end device, and may also be understood as an output voltage value of the transmitting end device.
In addition, in the embodiment of the present invention, since the terminal may be in the state to be charged or in the charging state within a period of time after the transmitting-end device accesses the charging port, for example, within a period of time before the terminal determines the charging power adjustment information (i.e., step 105). Therefore, in step 103, the charging power information sent by the transmitting end device to the terminal may include two meanings. Firstly, when transmitting end equipment transmits charging power information to a terminal for the first time, if the terminal is in a state to be charged, the charging power information can be understood as power information to be charged; secondly, when the transmitting terminal device sends the charging power information to the terminal, if the terminal is in a charging state, the charging power information can be understood as power information corresponding to the current charging signal.
And step 104, the terminal judges whether to adjust the charging power according to the charging power information sent by the transmitting terminal equipment and the rated power information of the charging port.
In this step, when the terminal receives the charging power information, the charging power information may be compared with a preset condition to determine whether the current charging power needs to be adjusted. The adjusting of the charging power may include, but is not limited to, adjusting the charging current.
During the wireless charging communication process, the communication packet may be lost for some reasons. In view of this, in the embodiment of the present invention, the transmitting device sends information related to power detection to the terminal, and the terminal determines whether to change the charging power after reading the information. Therefore, after the communication is ensured to work normally, the charging power is adjusted.
And 105, if the terminal judges that the charging power is adjusted, the terminal determines the charging power adjustment information.
And step 106, the terminal sends the charging power adjustment information to the transmitting terminal equipment.
In this step, when the terminal determines that the charging power needs to be adjusted, the terminal may determine charging power adjustment information according to the charging power information sent by the transmitting end device and the rated power information of the charging port, and send the determined charging power adjustment information to the transmitting end device.
In this step, the charging power adjustment information is determined by the terminal, and since the charging power adjustment information is determined by the terminal according to the charging power information sent by the transmitting terminal device and the rated power information of the charging port, the reliability of power detection in wireless charging can be ensured.
And step 107, the transmitting terminal equipment inputs a charging signal matched with the charging power adjustment information sent by the terminal to the terminal according to the charging power adjustment information sent by the terminal.
It should be noted that, in the above steps, steps 103 to 107 may be executed in a loop, so that the terminal can gradually adjust the charging power to the most appropriate charging power, thereby improving reliability, safety and stability of wireless charging.
As an optional implementation manner, in any step before the first execution of step 107, the embodiment of the present invention further includes the following steps:
the transmitting terminal equipment inputs a charging signal with a first charging current value to the terminal, wherein the first charging current value is preset and is smaller than the maximum current threshold value of the charging port;
the terminal receives a charging signal of which the first charging current value is input by the transmitting terminal equipment.
In this embodiment, after the transmitting end device is connected to the charging port, the transmitting end device may wirelessly charge the terminal, and the charging current of the transmitting end device is the first charging current value.
In consideration of stability and safety of wireless charging, it is preferable that the first charging current value is a small current value, for example, the first charging current value is 50 ma, 100 ma, 150 ma, or the like. That is, the transmitting-end device charges the terminal with a small current.
In order to better understand the technical solution of the embodiment of the present invention, the specific implementation of step 103 to step 107 is specifically described below with the charging power information as the charging voltage value.
Optionally, as shown in fig. 2, steps 103 to 107 include the following steps:
and step 1031, the transmitting terminal device sends the first charging voltage value to the terminal.
Step 1041, if the first charging voltage value is greater than the preset voltage threshold and the current charging current value of the terminal is smaller than the maximum current threshold of the charging port, the terminal determines to adjust the charging power.
Correspondingly, if the first charging voltage value is not greater than the voltage threshold value, or the current charging current value of the terminal is smaller than the maximum current threshold value of the charging port, the terminal determines not to adjust the charging power. In this case, the terminal determines that wireless charging is performed at the present charging current, and subsequent steps will not be performed.
Step 1051, the terminal determines that the charging power adjustment information is information for increasing the current charging current value to a second charging current value, where the second charging current value is smaller than or equal to the maximum current threshold of the charging port.
Step 1061, the terminal sends the charging power adjustment information to the transmitting end device.
Step 1071, the transmitting terminal device inputs the charging signal of the second charging current value to the terminal.
Step 1032, the transmitting terminal device sends the second charging voltage value to the terminal.
Step 1042, if the second charging voltage value is greater than the voltage threshold and the current charging current value of the terminal is smaller than the maximum current threshold of the charging port, the terminal determines to adjust the charging power.
Correspondingly, if the second charging voltage value is not greater than the voltage threshold value, or the current charging current value of the terminal is smaller than the maximum current threshold value of the charging port, the terminal determines not to adjust the charging power. In this case, the terminal determines that wireless charging is performed at the present charging current, and subsequent steps will not be performed.
In step 1052, the terminal determines the charging power adjustment information as information for increasing the current charging current value to a third charging current value, where the third charging current value is smaller than or equal to the maximum current threshold of the charging port.
Step 1062, the terminal sends the charging power adjustment information to the transmitting end device.
Step 1072, the transmitting terminal device inputs the charging signal of the third charging current value to the terminal.
……
Suppose that: the charging port is an SDP, and the maximum current threshold is 500 milliamperes; the voltage threshold is 4.5 volts.
When the first charging voltage value sent by the transmitting terminal device is greater than 4.5 volts (for example, 5.0 volts), the current charging current of the terminal is 100 milliamperes, the terminal determines that the charging power adjustment information is information for increasing the charging current (for example, increasing from 100 milliamperes to 200 milliamperes), and the transmitting terminal device inputs a charging signal to the terminal, so that the terminal is charged with the charging current of 200 milliamperes.
And the transmitting terminal device continues to send the second charging voltage value, if the second charging voltage value is reduced and still greater than 4.5 volts (for example, 4.9 volts) after the charging current of the terminal is increased to 200 milliamperes, the terminal determines that the charging power adjustment information is information for increasing the charging current (for example, increasing from 200 milliamperes to 300 milliamperes), and the transmitting terminal device inputs a charging signal to the terminal so that the terminal is charged with the charging current of 300 milliamperes.
When the charging voltage value reaches 4.5 volts, the terminal determines to wirelessly charge by the current charging current; or when the charging current reaches 500 milliamperes, the terminal determines to wirelessly charge at 500 milliamperes.
As an alternative implementation, the terminal determines the adjustment amplitude of the charging power according to the difference between the charging voltage value and the voltage threshold value.
Specifically, the larger the difference between the charging voltage value and the voltage threshold value is, the larger the adjustment range of the charging power is; the smaller the difference between the charging voltage value and the voltage threshold, the smaller the adjustment range of the charging power. For example, when the difference between the charging voltage value and the voltage threshold is 0.5 v, the adjustment range of the charging current value is 300 ma; when the difference value between the charging voltage value and the voltage threshold value is 0.2V, the adjustment amplitude of the charging current value is 100 milliamperes; and so on.
Thus, the embodiment can improve the efficiency of power detection of the terminal in wireless charging, thereby improving the charging efficiency and being beneficial to shortening the charging time.
Optionally, after the step of determining not to adjust the charging power if the charging voltage value sent by the transmitting end device is not greater than the voltage threshold, the method further includes:
if the terminal detects that the charging voltage value sent by the transmitting terminal equipment is smaller than the voltage threshold value, the terminal sends information of reducing the current charging current value to a fourth charging current value to the transmitting terminal equipment, wherein the fourth charging current value is smaller than the maximum current threshold value of the charging port.
In the wireless charging technology, the terminal and the transmitting terminal device are not physically connected. In this way, in the wireless charging process, if the position between the terminal and the transmitting terminal device changes, the charging power information of the charging port may also change accordingly, which may result in a decrease in wireless charging efficiency.
In view of this, after the terminal completes the power detection, the transmitting end device may send the charging power information of the charging port to the terminal at a certain interval, and the terminal performs real-time adjustment of the charging power according to the charging power information of the charging port.
If the terminal detects that the charging voltage value sent by the transmitting terminal device is smaller than the voltage threshold (for example, the charging voltage value is 4.4 v), it indicates that the charging efficiency tends to decrease. In order to ensure the safety and controllability of wireless charging, the terminal needs to adjust the charging power again. Specifically, the terminal sends information to the transmitting-end device to reduce the current charging current value to a fourth charging current value (for example, from 500 milliamps to 400 milliamps) so as to adapt the charging current value to the change of the charging voltage value.
It should be noted that, in addition to the technical solution proposed in the embodiment of the present invention, power detection in wireless charging may also add a dynamic load to the transmitting end device, and the transmitting end device is used to perform power detection alone. And after the terminal is accessed to the transmitting terminal equipment, the transmitting terminal equipment sends a power detection result to the terminal, and after the terminal is identified, the charging power is determined according to the design.
In this embodiment of the present invention, the terminal may be any device having a wireless charging function, for example: computers (Computer), Mobile phones, Tablet Personal computers (Tablet Personal Computer), notebook computers, palm top computers, vehicle-mounted terminals, Laptop computers (Laptop Computer), Personal digital assistants (PDA for short), Mobile Internet Devices (MID), Wearable devices (Wearable Device), pedometers, and the like.
In the embodiment of the invention, in the wireless charging process, the rated power information and the charging power information of the charging port are sent to the terminal through the transmitting terminal equipment, so that the terminal determines whether to adjust the charging power and the scheme of adjusting the charging power according to the information. Therefore, the power detection of the terminal in the wireless charging process can be realized, and the safety and controllability of the wireless charging method are improved.
