Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. 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.
In the related art, when the wireless charging base is used to wirelessly charge the mobile phone, the input power of the wireless charging base (the output power of the adapter) is not limited, and the input power of the wireless charging base is completely dependent on the input power required by the mobile phone. In an example, in the wireless charging process, when the input power of the mobile phone needs to be increased, a boost command can be sent to the charging base, so that when the wireless charging base receives the boost command, the input power of the wireless charging base can be automatically increased, and the input power required by the mobile phone is met. However, the higher the input power of the wireless charging base, the more easily the internal components of the wireless charging base are damaged, shortening the service life of the wireless charging base and even causing safety accidents.
Along with the development of wireless charging technology, people have higher and higher security requirements on wireless charging, and in order to ensure that users use the wireless charging base safely, the input power of the wireless charging base needs to be limited, so as to avoid safety accidents caused by overhigh input power of the wireless charging base.
In view of this, the disclosure provides a wireless charging control method, device and readable storage medium, so as to limit the input power of a power supply device in a wireless charging process, avoid a safety accident caused by the overhigh input power of the power supply device, and prolong the service life of the power supply device.
Before describing the wireless charging control method, the wireless charging control device and the readable storage medium provided by the present disclosure, a wireless charging system will be described first. Fig. 1 is a block diagram of a wireless charging system, according to an example embodiment. As shown in fig. 1, the wireless charging system may include a power supply apparatus 101 for supplying power and a power receiving apparatus 102 for receiving power, wherein the power supply apparatus 101 may perform wireless charging of the power receiving apparatus 102 and may perform wireless communication with the power receiving apparatus 102. Illustratively, the power supply device 101 may be a wireless charging base, and the power receiving device 102 may be a mobile terminal, such as a mobile phone, a tablet computer, a notebook, or the like.
When the power receiving apparatus 102 needs to be charged, the user needs to place the power receiving apparatus 102 within a preset range of the power supply apparatus 101. It is considered that the effective distance of wireless charging is within 10mm, and that the charging efficiency of the power receiving apparatus 102 differs when the power receiving apparatus 102 is placed at different positions of the power feeding apparatus 101. For example, the charging efficiency is maximum when the wireless charging back patch of the power receiving apparatus is aligned with the middle of the power supply apparatus, and the charging efficiency is lower the farther the wireless charging back patch of the power receiving apparatus is from the middle of the power supply apparatus, and therefore, in order to ensure the charging efficiency, the wireless charging back patch of the power receiving apparatus may be placed in alignment with the middle of the power supply apparatus (the positional relationship between the two during charging is not shown in fig. 1).
Fig. 2 is a flowchart illustrating a wireless charging control method applied to the power supply apparatus of fig. 1, according to an exemplary embodiment, which may include the following steps.
In step S21, an input power threshold of the power supply apparatus is acquired.
In the present disclosure, the input power threshold is the maximum power that the power supply device can provide in advance of safe power supply. Wherein the power sourcing equipment may obtain the input power threshold from a local, server, or powered device communicatively coupled thereto.
In one possible approach, the power sourcing equipment obtains the input power threshold from the powered device to which it is communicatively connected. For example, the power sourcing equipment determines whether a power control instruction sent by the powered device is received, wherein the power control instruction comprises an input power threshold. If the power control command is received, an input power threshold is obtained from the power control command. In this embodiment, when the power receiving apparatus is placed at a preset position of the power supplying apparatus to start charging, the power receiving apparatus establishes a communication connection with the power supplying apparatus, and the power receiving apparatus may then transmit the power control instruction to the power supplying apparatus. In this way, the power supply device may obtain the input power threshold from the power control instruction when receiving the power control instruction.
In another possible manner, if the power supply device does not receive a power control instruction, the input power threshold is actively obtained from the local. In this embodiment, the power supply device stores an input power threshold value in advance.
In yet another possible manner, if the power supply device does not receive the power control instruction, the power supply device may communicate with the cloud server to obtain the input power threshold from the cloud server.
Thus, the input power threshold is obtained in different modes, and the flexibility of wireless charging control is improved.
In step S12, the input power of the power supply device is monitored so that the input power of the power supply device is not higher than the input power threshold.
After the power supply equipment acquires the input power threshold, the input current and the input voltage of the power supply equipment are monitored in real time, and the input power is calculated, so that the input power of the power supply equipment is controlled to be not higher than the input power threshold.
In one possible embodiment, when the input power reaches the input power threshold, a prompt is sent to the powered device to cause the powered device to stop sending boost instructions to the power sourcing device when the prompt is received.
The power supply device is a wireless charging base, a wireless charging transmitting chip in the wireless full base monitors input current and input voltage in real time and calculates input power, and when the wireless charging transmitting chip monitors that the input power reaches an input power threshold, early warning information (i.e. prompt information) that the input power of the wireless full base reaches the input power threshold is sent to the power receiving device, so that the power receiving device stops sending a boosting instruction to the wireless charging base when receiving the early warning information. As described above, the wireless charging base will automatically raise its input power when receiving the boost command to meet the input power required by the powered device, so in this embodiment, if the powered device stops sending the boost command to the wireless charging base, the wireless charging base will not continue to boost, and thus the input power of the wireless charging base will not increase, so that the purpose of limiting the input power of the wireless charging base not to be higher than the input power threshold can be achieved.
In another possible embodiment, when the input power reaches the input power threshold, if a boost command sent by the powered device is received, the response to the boost command is prohibited. For example, when the power supply apparatus determines that the input power reaches the input power threshold, early warning information indicating that the input power has reached the input power threshold is not transmitted to the power receiving apparatus, at this time, the power receiving apparatus may still transmit a step-up instruction to the power supply apparatus if higher power is required. For another example, even if the power supply apparatus transmits warning information indicating that the input power has reached the input power threshold to the power receiving apparatus, the power receiving apparatus transmits a step-up instruction to the power supply apparatus. Therefore, in the above case, in order to further limit the input power of the power supply apparatus, the power supply apparatus prohibits responding to the step-up instruction even if the step-up instruction is received.
By adopting the technical scheme, in the wireless charging process, the power supply equipment monitors the input power of the power supply equipment so that the input power of the power supply equipment is not higher than the input power threshold value, and therefore, in the wireless charging process, the input power of the power supply equipment is limited, the safety accident caused by the overhigh input power of the power supply equipment is avoided, and the service life of the power supply equipment is prolonged.
Fig. 3 is a flowchart illustrating another wireless charging control method according to an exemplary embodiment. As shown in fig. 3, the method may include the following steps.
In step S31, it is determined whether a power control instruction transmitted by the power receiving apparatus is received. Wherein the power control instruction includes an input power threshold of the power supply device. If not, the step S32 is executed, and if received, the steps S33 and S34 are executed.
In step S32, an input power threshold is acquired from the local.
In step S33, an input power threshold is acquired from the power control instruction.
In step S34, feedback information indicating that a power control instruction has been received is transmitted to the power receiving apparatus.
In the present disclosure, when the power supply apparatus receives the power control instruction, feedback information indicating that the power control instruction has been received may be sent to the power receiving apparatus to inform the power receiving apparatus that the communication connection between the power receiving apparatus and the power supply apparatus is normal, and communication may be performed.
The values are described in the present disclosure, the order of executing the step S33 and the step S34 may not be limited, and the step S33 may be executed first and then the step S34 may be executed (as shown in fig. 3), the step S34 may be executed first and then the step S34 may be executed, or the step S33 and the step S34 may be executed simultaneously.
In step S35, when the input power reaches the input power threshold, a prompt message is sent to the power receiving apparatus. And the power receiving equipment stops sending the boosting instruction to the power supply equipment when receiving the prompt information.
The value is explained by executing step S35 after executing step S32 or step S34.
In step S36, it is determined whether a step-up instruction transmitted by the power receiving apparatus is received. If the execution step S37 is received, otherwise, the execution step S36 is continued.
In step S37, the response to the step-up instruction is prohibited.
For example, when the power receiving apparatus does not receive the prompt information sent by the power supply apparatus, the power receiving apparatus still sends the step-up instruction to the power supply apparatus when the power receiving apparatus needs higher input power. As another example, even if the power receiving apparatus receives the prompt information sent by the power supplying apparatus, it is possible to continue sending the step-up instruction to the power supplying apparatus. In both cases, in order to avoid an increase in the input power of the power supply apparatus, the response to the step-up instruction is also prohibited when the step-up instruction is received.
By adopting the technical scheme, in order to avoid that the power supply equipment still receives the boosting instruction sent by the power receiving equipment after sending the prompt information, the input power is improved according to the boosting instruction, and the power supply equipment is further controlled to not respond to the boosting instruction even if receiving the boosting instruction, so that the input power of the power supply equipment is limited, and the safety of the power supply equipment is further improved.
Fig. 4 is a flowchart illustrating another wireless charging control method that is applied to the powered device in fig. 1, according to an exemplary embodiment, and may include the following steps.
In step S41, a power control instruction is transmitted to the power supply apparatus. The power control command comprises an input power threshold of the power supply equipment, so that the input power of the power supply equipment is monitored when the power control command is received by the power supply equipment, and the input power of the power supply equipment is not higher than the input power threshold.
For example, the power receiving device is provided with a man-machine interaction interface, and at the beginning of wireless charging, a user can input an input power threshold value of the power supply device in a text form or a voice form in the man-machine interaction interface, and the power supply device can generate a power control instruction based on the input power threshold value and send the power control instruction to the power supply device. In another example, a default input power threshold is stored in the power receiving device in advance, and the power receiving device generates a power control command based on the default input power threshold and transmits the power control command to the power supply device at the start of wireless charging.
In the present disclosure, the power receiving device may be a mobile phone with a wireless charging function, and when the mobile phone is placed on a power supply device, for example, a wireless charging base, the mobile phone may communicate with the power supply device, and further send a power control instruction to the power supply device. For example, the control center of the mobile phone sends a power control instruction to the wireless charging transmitting chip of the wireless charging base through the wireless charging receiving chip of the mobile phone.
In step S42, it is determined whether or not the prompt information sent by the power supply apparatus is received. The prompt information is used for representing that the input power of the power supply equipment reaches an input power threshold.
As described above, after receiving the power control instruction sent by the power receiving apparatus, the power supplying apparatus monitors its input power, and when the input power reaches the input power threshold, it sends a prompt message to the power receiving apparatus. In this way, the powered device can determine whether the input power of the power supply device reaches the input power threshold according to whether the powered device receives the prompt message.
In step S43, if the prompt message is received, the step-up instruction is prohibited from being sent to the power supply apparatus.
When the power receiving device receives the prompt information, the power receiving device indicates that the input power of the power supply device reaches the input power threshold, at this time, the input power of the power receiving device cannot be increased any more, the current input power of the power receiving device is set to be the maximum value, and no higher power is pulled, namely, the power receiving device does not send a boosting instruction to the power supply device any more.
The values illustrate that the powered device is placed in a different location of the power sourcing device, its charging efficiency is different, and the output power of the power sourcing device is also slightly different from its own input power, so the current input power of the powered device and the input power of the power sourcing device are not necessarily the same in this disclosure.
By adopting the scheme, when the power receiving equipment acquires that the input power of the power supply equipment reaches the input power threshold, the power receiving equipment prohibits sending a boosting instruction to the power supply equipment, so that the aim of limiting the input power of the power supply equipment not to be higher than the input power threshold can be fulfilled, safety accidents caused by the fact that the input power of the power supply equipment is too high are avoided, and the service life of the power supply equipment is prolonged.
Further, when the power supply apparatus receives the power control instruction, feedback information indicating that the power control instruction has been received may be transmitted to the power receiving apparatus to inform the power receiving apparatus. Illustratively, the method may further comprise: and determining whether feedback information sent by the power supply equipment and used for representing that the power control instruction is received or not. Accordingly, the specific implementation manner of determining whether the prompt message sent by the power supply device is received in step S42 may be: if the feedback information is received, determining whether prompt information sent by the power supply equipment is received.
In this example, if the power receiving apparatus receives the feedback information, it indicates that the communication between the power receiving apparatus and the power supplying apparatus is normal, and at this time, it is determined whether the prompt information sent by the power supplying apparatus is received. For example, if it is determined that the prompt information sent by the power supply device is received, the input power of the power supply device reaches the input power threshold, and if it is determined that the prompt information sent by the power supply device is not received, it may be determined that the input power of the power supply device has not reached the input power threshold, instead of that the prompt information is not received because of disconnection of communication, so that erroneous judgment of the input power of the power supply device may be avoided.
In addition, if feedback information of the power supply equipment is not received, controlling the input power of the power receiving equipment not to exceed a preset value, wherein the preset value is the product of an input power threshold value and preset charging efficiency.
In the present disclosure, if feedback information of the power supply device is not received, it is unclear whether the power supply device receives the input power threshold and whether communication between the two is abnormal, and at this time, in order to ensure that the input power of the power supply device does not exceed the input power threshold, the power receiving device needs to actively control the input power thereof not to exceed a preset value. The preset value is the product of the input power threshold value and the preset charging efficiency, wherein the value range of the preset charging efficiency is 0-1.
By adopting the technical scheme, when the power receiving equipment does not receive feedback information, the input power of the power supply equipment is limited by limiting the input power of the power receiving equipment, so that safety accidents caused by overhigh input power of the power supply equipment are avoided, and the service life of the power supply equipment is prolonged.
