It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
It should be understood that the Mobile terminal according to the embodiment of the present invention may be, for example, a Mobile phone (e.g., an Android Mobile phone, an iOS Mobile phone, etc.), a tablet computer, a palm computer, a Mobile Internet Device (MID), a Personal Digital Assistant (PDA), a wearable device, and other terminal Devices. The Mobile terminal may also be referred to as a User Equipment (UE), a terminal, a wireless terminal or a Mobile Station (MS), and the like, which is not limited in the embodiments of the present invention. In the embodiment of the present invention, the mobile terminal may be wirelessly charged by using a wireless charging device.
The embodiment of the invention discloses a wireless charging method, a mobile terminal, wireless charging equipment and a wireless charging system, which can reduce energy consumption in a wireless charging process and shorten wireless charging time by adjusting the magnitude of wireless charging current. The details are described below.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a wireless charging method according to an embodiment of the present invention. Specifically, the method according to the embodiment of the present invention may be specifically applied to the mobile terminal described above. As shown in fig. 1, the wireless charging method according to the embodiment of the present invention may include the following steps:
101. a charging request is sent to the wireless charging device.
102. And when a charging response message returned by the wireless charging equipment for the charging request is received, acquiring the battery voltage value of the mobile terminal.
Optionally, the charging response message may be sent to the mobile terminal by the wireless charging device after receiving a charging request sent by the mobile terminal, by acquiring the number of currently connected charging terminals, and when it is determined that the number of connected charging terminals is lower than a preset number threshold.
Optionally, after establishing a communication connection with the wireless charging device, the mobile terminal may determine that there is a relationship between the mobile terminal and the wireless charging device when receiving a charging response message returned by the wireless charging device in response to a charging request sent by the mobile terminal, or further when detecting that the wireless charging device performs wireless charging on the wireless charging device by using a preset minimum charging current, for example, the charging current is lower than a preset threshold, so that the mobile terminal may obtain a battery voltage value of the mobile terminal in a wireless charging process. Further optionally, the mobile terminal may acquire the battery voltage value thereof according to a preset acquisition frequency. Wherein the preset acquiring frequency can be set by a manufacturer of the mobile terminal.
103. And determining an adaptive current value corresponding to the acquired battery voltage value.
For each battery voltage value of the mobile terminal, an optimal charging current value corresponds to the battery voltage value. The optimal charging current value can ensure that the charging time of the mobile terminal is shortest under the condition of ensuring the charging safety. In this embodiment, after obtaining the battery voltage value, the mobile terminal may calculate the optimal charging current value corresponding to the battery voltage value in real time. Or, the mobile terminal may determine an optimal charging current value corresponding to the acquired battery voltage value according to a correspondence between a preset battery voltage value and an adaptation current value, or may be referred to as an adaptation current value. Of course, the mobile terminal may also determine the adaptive current value in other manners, which is not limited in the embodiment of the present invention.
104. And sending the determined adaptation current value to the wireless charging equipment so that the wireless charging equipment enables the induced current to reach the adaptation current value by adjusting the magnetic field change rate, and wirelessly charging the mobile terminal by adopting the adaptation current value.
Optionally, in order to enable the wireless charging device to charge the mobile terminal with the adaptation current value, the mobile terminal may send the determined adaptation current value to the wireless charging device connected to the mobile terminal. Whereas according to faraday's law of electromagnetic induction and closed current ohm's law, a change in the rate of change of the magnetic field (the rate of change of the magnetic field) causes a change in the induced current. Therefore, when receiving the adapted current value, the wireless charging device may adjust the magnetic field change rate to make the induced current reach the adapted current value.
Optionally, in the wireless charging process, the mobile terminal may determine whether to remind the user of terminating the wireless charging process by detecting whether the electric quantity value of the mobile terminal exceeds a preset first electric quantity threshold, or instruct the wireless charging device connected to the mobile terminal to charge the wireless charging device. Further optionally, the mobile terminal may further determine whether to terminate the wireless charging process by detecting whether the electric quantity value of the mobile terminal exceeds a preset second electric quantity threshold. The measure of the electric quantity value may be a value of a current electric quantity of the mobile terminal, or a ratio of the value of the current electric quantity of the mobile terminal to a battery capacity of the mobile terminal, such as a current electric quantity percentage. The preset measure of the charge threshold should be consistent with the measure of the charge value, for example, when the measure of the charge value is a numerical value, the measure of the charge threshold is a numerical value accordingly. Optionally, the first power threshold is lower than the second power threshold. The mobile terminal may detect the electric quantity value according to a preset detection frequency, where the preset detection frequency may be set by a manufacturer of the mobile terminal or may be set by a user in a customized manner, and the embodiment of the present invention is not limited thereto.
Specifically, if it is detected that the electric quantity value of the mobile terminal does not exceed the preset first electric quantity threshold, the mobile terminal may repeatedly perform steps 102, 103, and 104 to instruct the wireless charging device connected thereto to wirelessly charge the mobile terminal with the adaptive current value. Otherwise, the mobile terminal can output a human-computer interaction interface for reminding the user whether to stop wireless charging.
Optionally, if a charging stop instruction input from the human-computer interface by the user is received, the mobile terminal may terminate the wireless charging process. If the charging stopping instruction input by the user from the man-machine interaction interface is not received, or the reminding result is not received from the man-machine interaction interface, the mobile terminal can default the current electric quantity value and cannot meet the power storage requirement of the user. Therefore, the mobile terminal may repeatedly perform steps 102, 103 and 104 to instruct the wireless charging device connected thereto to continue wireless charging the mobile terminal with the adapted current value.
Optionally, when it is detected that the electric quantity value of the mobile terminal reaches the preset first electric quantity threshold, in order to prolong the battery life, it may be considered that the current electric quantity value of the mobile terminal has already satisfied the basic electric storage requirement. Therefore, when the electric quantity value of the mobile terminal is detected to exceed the preset first electric quantity threshold value, the mobile terminal can remind a user whether the wireless charging process needs to be terminated or not in a mode of outputting a human-computer interaction interface. In particular, the preset first power threshold may be, for example, 80%.
Specifically, if it is detected that the electric quantity value of the mobile terminal exceeds the preset second electric quantity threshold, the mobile terminal may terminate the wireless charging process. The manner of terminating the wireless charging process by the mobile terminal may include: and disconnecting the wireless connection between the mobile terminal and the wireless charging equipment, or sending a charging stop notification message to the wireless charging equipment to instruct the wireless charging equipment to stop wirelessly charging the mobile terminal.
Optionally, when it is detected that the electric quantity value of the mobile terminal reaches the preset second electric quantity threshold, it may be considered that the electric quantity value of the mobile terminal has satisfied the full-electricity demand. Therefore, when the electric quantity value of the mobile terminal is detected to exceed the preset second electric quantity threshold value, the mobile terminal can automatically terminate the wireless charging process. Specifically, to prevent the battery from being overcharged, the preset second charge amount threshold may be 99%, for example.
Optionally, the first power threshold and the second power threshold may be set by a manufacturer of the mobile terminal, or may be set by a user of the mobile terminal. Further optionally, in the mobile terminal, only one electric quantity threshold may be set to implement the function of performing charging protection on the battery by using the preset second electric quantity threshold.
In the embodiment of the invention, the mobile terminal can send a charging request to the wireless charging equipment, determine the adaptive current value corresponding to the current battery voltage value when receiving a charging response message sent by the wireless charging equipment when detecting that the number of the connected charging terminals is lower than the preset number threshold, send the adaptive current value to the connected wireless charging equipment to instruct the wireless charging equipment to charge the mobile terminal by adopting the adaptive current value, and charge and protect the battery by setting the first electric quantity threshold and the second electric quantity threshold, so that under the condition of ensuring the charging safety, the energy consumption in the wireless charging process can be reduced by adjusting the size of the wireless charging current, and the wireless charging time length can be shortened.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating another wireless charging method according to an embodiment of the present invention. In particular, the method of the embodiment of the present invention may be specifically applied to the wireless charging device, such as a wireless charger. As shown in fig. 2, the wireless charging method according to the embodiment of the present invention may include the following steps:
201. when a charging request of a mobile terminal is received, the number of connected charging terminals is acquired.
202. And judging whether the number of the connected charging terminals is lower than a preset number threshold value.
203. And when the number of the connected charging terminals is lower than the number threshold, sending a charging response message to the mobile terminal.
Optionally, the wireless charging device may establish a communication connection with the mobile terminal in a wireless connection manner. The wireless connection mode may include: wireless Fidelity (Wi-Fi for short), Bluetooth, ZigBee, infrared connection and the like. During the communication connection hold, the wireless charging device may receive various messages or data transmitted by the mobile terminal, such as a charging request transmitted by the mobile terminal, a transmitted adaptation current value, and so on.
Wherein a number threshold may be preset for indicating the maximum number of terminals connectable on the wireless charging apparatus to ensure charging efficiency. The number threshold may be set in conjunction with the charging capability of the wireless charging device, such as according to its configuration parameters, or may be set by a user-defined setting. Specifically, after receiving a charging request sent by a mobile terminal, the wireless charging device may obtain the number of charging terminals that are currently connected, that is, the number of terminals that are currently being charged by the wireless charging device or need to pass through the wireless charging device. Therefore, the mobile terminal can be charged by comparing the acquired number of the connected charging terminals with the number threshold, determining to respond to the charging request sent by the mobile terminal when the number is lower than the number threshold, and returning a charging response message to the requesting mobile terminal to indicate that the charging request of the mobile terminal is accepted.
204. And receiving the adaptive current value sent by the mobile terminal aiming at the charging response message.
Further optionally, after the communication connection is established with the mobile terminal, before the adaptive current value sent by the mobile terminal is received, the wireless charging device may perform wireless charging, that is, blind charging, on the mobile terminal by using a preset minimum charging current, so that the charging may be performed according to a current required at a minimum without knowing how much the battery voltage is. The preset minimum charging current may be preset for the mobile terminal, or may be preset for the wireless charging device. In a specific implementation, the minimum charging current preset for the mobile terminal and the minimum charging current preset for the wireless charging device may not be equal.
205. And adjusting the magnetic field change rate to enable the induced current to reach the adaptive current value, and wirelessly charging the mobile terminal by adopting the adaptive current value.
Conditions under which persistent current is present in the circuit include: the circuit is closed and there is a power supply. Therefore, when the mobile terminal needs to be wirelessly charged, the wireless charging device can be connected with a power supply.
The magnitude of the induced electromotive force in a closed circuit is proportional to the rate of change of the magnetic flux through such circuit, according to faraday's law of electromagnetic induction. Therefore, aiming at the wireless charging technology applying the electromagnetic induction principle, when the mobile terminal sends the determined adaptive current value to the wireless charging equipment connected with the mobile terminal, the wireless charging equipment can change the change rate of the magnetic flux by adjusting the change rate of the magnetic field, so that the value of the induced electromotive force is changed. And the magnitude of the current in the closed circuit is proportional to the electromotive force of the power supply according to the ohm's law of the closed circuit. It can be concluded that when the induced electromotive force changes, the induced current will change accordingly. In summary, the wireless charging device can adjust the magnetic field change rate to make the induced current reach the adaptive current value of the mobile terminal.
Under the current-limiting constant-voltage charging mode adopted at present, the charging current output by the wireless charging equipment is usually larger than or smaller than the adaptive current value of the mobile terminal. On one hand, when the charging current output by the wireless charging equipment is larger than the adaptive current value of the mobile terminal, the energy consumption of the power supply is increased; on the other hand, when the charging current output by the wireless charging equipment is smaller than the adaptive current value of the mobile terminal, the charging time of the battery is increased. In this embodiment, the wireless charging device may make the output charging current equal to or approximately equal to the adaptation current value of the mobile terminal by adjusting the magnetic field change rate in real time, so as to improve the charging efficiency.
Optionally, in the wireless charging process, when a charging stop confirmation instruction input by a user is received, or it is detected that the electric quantity value of the mobile terminal reaches a preset electric quantity threshold value meeting a full-power requirement, the mobile terminal may send a charging stop notification message to the wireless charging device connected to the mobile terminal. Thus, the wireless charging apparatus can receive the charging stop notification message transmitted by the mobile terminal and stop wirelessly charging the mobile terminal in response to the charging stop notification message to prevent overcharging the battery.
In the embodiment of the invention, when receiving a charging request sent by a mobile terminal, a wireless charging device can obtain the number of connected charging terminals, determine to charge the mobile terminal when detecting that the number of the connected charging terminals is lower than a preset number threshold, specifically receive an adaptive current value sent by the mobile terminal and enable an induced current to reach the adaptive current value of the mobile terminal by adjusting the magnetic field change rate of the adaptive current value, so as to charge the mobile terminal by adopting the adaptive current value, and actively stop charging the mobile terminal when receiving a charging stop notification message sent by the mobile terminal, so that under the condition of ensuring the charging safety, the energy consumption in the wireless charging process can be reduced by adjusting the size of the wireless charging current, and the wireless charging duration can be shortened.
Referring to fig. 3, fig. 3 is an interaction diagram of a wireless charging method according to an embodiment of the present invention. In particular, the method of the embodiment of the present invention may be specifically applied to the mobile terminal and the wireless charging device. As shown in fig. 3, the wireless charging method according to the embodiment of the present invention may include the following steps:
301. the mobile terminal sends a charging request to the wireless charging device.
Optionally, the mobile terminal may send the charging request to the wireless charging device, such as a wireless charging device within a preset distance range from the terminal, when receiving a charging instruction triggered based on a user operation, for example, by clicking a preset key, or by placing the terminal in a certain charging induction area, or making a certain gesture action, or when the terminal electric quantity is lower than a threshold value and needs to be charged, and the like.
302. The wireless charging device acquires the number of the connected charging terminals and judges whether the number is lower than a preset number threshold.
303. And the wireless charging equipment sends a charging response message to the mobile terminal.
Specifically, the wireless charging device may return a charging response message responding to the charging request to the mobile terminal when determining that the number is lower than the preset number threshold. Further, if the number is not less than the number threshold, a charging request failure message may be returned to the mobile terminal.
304. The mobile terminal obtains a battery voltage value thereof.
