in the charging process, a charging parameter on the device to be charged is acquired, and/or an input parameter input to the device to be charged is acquired, step 201.
In this step, the charged device is a charging object of the wireless charging processing device, which may be a mobile phone, a computer or an iPad, or may be other devices, the charging parameter on the charged device is a parameter of a battery of the charged device in the wireless charging process, specifically, a battery level, a battery voltage, a battery temperature and a battery current, where the battery level is a battery level at a certain time in the wireless charging process, the battery voltage is a battery voltage at a certain time in the wireless charging process, the battery temperature is a battery temperature at a certain time in the wireless charging process, the battery current is a battery current at a certain time in the wireless charging process, the obtained charging parameter is a parameter at a certain time in the wireless charging process, and in addition, the wireless charging processing device may be configured to monitor the charging parameter of the charged device at regular time or in real time, therefore, the condition of the battery of the charged equipment can be monitored in time, and the wireless charging process is not interrupted.
In addition, the wireless charging processing device may obtain, in addition to the charging parameter of the charged device, an input parameter input to the charged device, where the obtained input parameter is a parameter input to the charged device by the wireless charging processing device at a certain time in the wireless charging process, and the input parameter may be an input voltage and an input current. The wireless charging processing equipment monitors whether the communication signal is still in a stable state in the wireless charging process through acquiring the input parameters.
In this step, the wireless charging processing device can monitor the battery of the charged device more comprehensively in the wireless charging process by acquiring the charging parameters of the charged device and/or the input parameters input to the charged device in a timed or real-time manner, and can improve the accuracy of determining the state of the communication signal by monitoring a plurality of parameters, thereby providing a more reliable basis for the control of the subsequent input parameters.
And step 202, correspondingly controlling the input parameters input to the charged equipment according to the charging parameters and/or the input parameters.
In this step, the input parameters input to the charged device are correspondingly controlled, wherein the input parameters include the voltage and the current input to the charged device, and the wireless charging processing device correspondingly controls the input parameters according to the acquired charging parameters and/or the input parameters.
Specifically, the wireless charging processing device correspondingly controls the input parameters input to the device to be charged according to the acquired parameter information, that is, controls the input parameters according to the acquired charging parameters and/or the input parameters input to the device to be charged, and the following conditions may be included: the input parameters are controlled only according to the charging parameters, or the input parameters are controlled only according to the input parameters input to the charged equipment, or the input parameters are controlled according to the charging parameters and the input parameters input to the charged equipment, so that the communication signals are more stable, the power transmitting end of the wireless charging processing equipment can demodulate the communication signals normally, and the normal operation of the wireless charging process is ensured.
In the processing method for wireless charging provided by this embodiment, in the charging process, a charging parameter on a device to be charged is obtained, and/or an input parameter input to the device to be charged is obtained; and correspondingly controlling the input parameters input to the charged equipment according to the charging parameters and/or the input parameters. The charging parameters of the charged device and/or the input parameters input to the charged device are regularly monitored and acquired in the charging process, the stable state of the communication signals in the wireless charging process is determined according to the acquired charging parameters and/or the input parameters, and the input parameters input to the charged device are controlled according to the stable state of the communication signals, namely, the charging parameters on the charged device and/or the input parameters input to the charged device are monitored in real time, and the input parameters input to the charged device are timely adjusted, so that the stability of the communication signals of the charged device in the charging process can be improved.
Fig. 3 is a flowchart illustrating a processing method of wireless charging according to an exemplary embodiment, and this embodiment describes in detail how to perform a corresponding control process on an input parameter input to a device to be charged according to the input parameter based on the embodiment illustrated in fig. 2, and as illustrated in fig. 3, the determining method includes the following steps.
In the charging process, a charging parameter on the device to be charged and/or an input parameter input to the device to be charged are obtained in step 301.
Step 301 is similar to step 201 and will not be described herein again.
In this step, the input voltage is a voltage input to the device to be charged by the wireless charging processing device at a certain time in the wireless charging process, the input voltage is a voltage preset by the charging device and can be set according to the condition of the device to be charged, and whether the device to be charged performs quick charging is determined by the input voltage in the acquired input parameters, where quick charging is a manner in which the wireless charging processing device charges the device to be charged, and the voltage of quick charging is generally higher than the voltage of normal charging, so the charging time of quick charging is faster than the rate of normal charging.
In this step, when the wireless charging processing device determines to rapidly charge the device to be charged, the wireless charging processing device further determines whether the input current in the input parameter is smaller than a preset input current threshold, specifically, assuming that the voltage of the wireless charging processing device for fast charging the device to be charged is 9V, the preset input current threshold is 100mA, when the wireless charging processing device monitors that the input voltage at the current moment is 9V, namely, the acquired input voltage is 9V, which is the quick charging voltage set by the wireless charging processing device, and determining that the charged device is rapidly charged, at this time, the wireless charging processing device continues to monitor the input current at the current moment, and if the monitored input current is 80mA, that is, the acquired input current 80mA is smaller than a preset input current threshold, determining that the input current is smaller than the preset input current threshold.
The threshold of the input current is a current value preset by the wireless charging processing device, the preset value is smaller than the current value in the charging state, and can be set to be 100mA, 50mA or 20mA, and the like, and certainly can be set according to requirements, and the threshold of the input current is not limited in any way in the disclosure.
In the step, after the input current is determined to be smaller than the preset input current threshold value, the input voltage is reduced to the common charging voltage, the input current corresponding to the input voltage is configured, and the charged device is continuously charged; the input voltage of the ordinary charging is smaller than the input voltage of the quick charging, and the input current of the ordinary charging is larger than the input current of the quick charging, so that the input current needs to be correspondingly configured while the input voltage is reduced, and the configuration corresponds to the reduced input voltage, so that the influence on the communication signal in the wireless charging process is small, and the communication signal can be better demodulated by the transmitting end of the wireless charging.
In the processing method for wireless charging provided in this embodiment, in the charging process, whether to rapidly charge the device to be charged is determined by acquiring the input parameter input to the device to be charged and according to the input voltage in the acquired input parameter; if the fact that the wireless charging processing equipment carries out rapid charging on the charged equipment is determined, further determining whether the input current in the input parameters is smaller than a preset input current threshold value; if the input current input into the charged device is smaller than the preset input current threshold value, the input voltage is reduced to realize common charging of the charged device, and meanwhile, the input current corresponding to the reduced input voltage is configured. The communication signal in the wireless charging process is judged to be in a stable state or not by monitoring regularly and acquiring the input parameters input to the charged equipment, and then the input parameters are adjusted, so that the communication signal in the wireless charging process can be continuously in the stable state.
Fig. 4 is a flowchart illustrating a processing method of wireless charging according to an exemplary embodiment, where in the present embodiment, on the basis of the embodiment illustrated in fig. 2, when the charging parameters include: the detailed description of how to perform the corresponding control process on the input parameters input to the device to be charged according to the charging parameters when the battery power, the battery voltage and the battery current are used is shown in fig. 4.
Step 401 is similar to step 201 and will not be described herein again.
In this step, according to the electric quantity of the battery, the voltage of the battery, and the current of the battery in the acquired charging parameters, the electric quantity threshold of the battery, the voltage threshold of the battery, and the current threshold of the battery are respectively compared and judged with a preset electric quantity threshold of the battery, and then it is determined whether the acquired charging parameters meet the preset threshold, where the electric quantity threshold of the battery is the minimum electric quantity of the battery for the wireless charging processing device to reduce the input voltage, the voltage of the battery is the minimum battery voltage for the wireless charging processing device to reduce the input voltage, and the current of the battery is the minimum battery current for the wireless charging processing device to reduce the input voltage.
Specifically, for example, it is assumed that the wireless charging processing device presets a threshold of the battery power in the charging parameter as 95%, a voltage threshold of the battery as 8V, and a current threshold of the battery as 500mA, when the wireless charging processing device is at a certain time in the process of charging the device to be charged, the monitored battery power is 96%, the battery voltage is 9V, and the current of the battery is 600mA, that is, 96% of the monitored battery power in the charging parameter meets the preset power threshold 95%, the voltage of the battery 9V meets the preset voltage threshold 8V, and the current of the battery 600mA meets the preset current threshold 500 mA.
In this step, if it is determined that the battery power, the battery voltage, and the battery current in the charging parameters all meet the corresponding threshold values, the wireless charging processing device may decrease the input voltage input to the device to be charged to the input voltage for normal charging, configure the input current, and configure the input current to be the input current corresponding to the decreased input voltage. Therefore, the influence on the communication signal in the wireless charging process is small, so that the transmitting end of the wireless charging can demodulate the communication signal better.
In the wireless charging processing method provided by this embodiment, in the wireless charging process, by determining whether the electric quantity of the battery meets a preset electric quantity threshold, whether the voltage of the battery meets a preset battery voltage threshold, and whether the current of the battery meets a preset current threshold, if the electric quantity of the battery meets the preset battery voltage threshold, the input voltage is reduced to implement ordinary charging of the charged device, and the corresponding input current is configured, that is, the stability of the communication signal is ensured by reducing the input voltage and configuring the corresponding input current.
Optionally, when the charging parameters include: the battery power, then according to the charging parameter, carry out corresponding control to the input parameter of being input to on the equipment that is charged, it is specific: acquiring a battery state according to the electric quantity of the battery; and when the battery state meets the condition of full battery charge, reducing the input voltage in the input parameters to realize common charging of the charged equipment, and configuring the input current corresponding to the reduced input voltage.
Specifically, when the device to be charged is in a charging process, the battery state of the device to be charged is determined according to the battery power in the charging parameter acquired by the wireless charging processing device, where the battery state may be a battery charging state and a battery full charge state, the battery power in the specific battery full charge state may be 95%, 99%, or 100%, or certainly may be a range, for example, the battery power is 95% -100%, and the disclosure is not limited.
And when the electric quantity of the battery is determined to be in a full-charge state, reducing the input voltage input to the charged equipment to carry out ordinary charging, and simultaneously configuring the input current and configuring the input current into the input current corresponding to the reduced input voltage. Therefore, the influence on the communication signal in the wireless charging process is small, so that the transmitting end of the wireless charging can demodulate the communication signal better.
Optionally, when it is determined that the battery state meets the condition of full battery charge, acquiring a screen state of the charged device; the input current is adaptively configured according to the screen state.
Specifically, when the state of the battery is monitored to be in accordance with the condition that the battery is fully charged, the wireless charging processing device acquires the screen state of the charged device at the current moment, the screen state can be on or off, when the screen of the charged device is monitored to be in the on state, the input current input to the charged device is adaptively adjusted to meet the requirement of the battery of the charged device, and when the screen of the charged device is monitored to be in the off state, the input current input to the charged device is correspondingly configured.
In an actual application process, when a battery of a charged device is in a full charge state, when a screen of the charged device is opened, the battery needs to compensate an input current in order to ensure normal use or operation of the charged device, and therefore, the battery of the charged device is still in the full charge state through adaptive configuration of the input current, the adaptive configuration of the input current can be to compensate the input current to a minimum operable current value, and for a specific minimum operable current value, the present disclosure does not make any limitation.
Optionally, when it is determined that the battery state is switched from the battery full charge state to the battery charging state, acquiring the battery electric quantity in the charging parameters; and if the electric quantity of the battery is smaller than a preset first gear threshold value, the charged equipment is charged normally.
Specifically, when the wireless charging processing device monitors that the battery of the charged device is switched from the battery full charge state to the battery charging state, the wireless charging processing device will acquire the specific battery electric quantity of the charged device at the current moment, compare the acquired battery electric quantity with a preset first gear threshold value, and perform ordinary charging on the charged device if the acquired battery electric quantity is smaller than the preset first gear threshold value, where the preset first gear threshold value of the battery electric quantity is the maximum battery electric quantity that the wireless charging processing device needs to perform ordinary charging on the charged device, and the preset first gear threshold value may be 90%, 80%, 72%, and the like, and may be set according to specific conditions, which is not limited by the present disclosure.
