[0042] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0043] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0044] The present disclosure is mainly applied in wireless charging scenarios. The communication noise of wireless charging is relatively large under low load conditions. Since the communication frequency is about 2kHz, which is within the hearing range of the human ear, it affects the charging experience of users in rest scenarios and also has an adverse effect on other modules.

[0045] In order to solve the above problems, the present disclosure provides a communication method, device and storage medium. The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings.

[0046] Figure 1 is a flow chart of a communication method according to an exemplary embodiment, which can be applied to a wireless charging receiving end (i.e., an electronic device supporting wireless charging, such as a mobile phone, etc.), such as Figure 1 As shown, the method comprises the following steps:

[0047] In step S101, according to the charging parameters corresponding to the wireless charging receiving end, the target communication capacitor corresponding to the charging parameters is determined, wherein the charging parameters represent the size of the charging load, and different charging parameters correspond to communication capacitors of different capacitance values.

[0048] For example, the charging parameter may include one or more of the load current (or pull current) for wireless charging, the rectified voltage during wireless charging, the actual charging power, etc. It is understandable that the magnitude of the above charging parameters can represent the magnitude of the charging load.

[0049] In addition, the communication capacitor may be, for example, a COM capacitor provided in the wireless charging circuit. The communication capacitor may be used to adjust the ripple size of the communication signal transmitted during the wireless charging process so that the receiving end of the communication signal can correctly parse the received data packet.

[0050] During the wireless charging process, communication signals are transmitted between the wireless charging receiving end and the wireless charging transmitting end, and the greater the ripple amplitude of the communication signal, the greater the noise during the transmission of the communication signal. The communication signal is transmitted through current, and the current signal has a large ripple under low load conditions. When the alternating current passes through the capacitor, the current ripple is large, and the capacitor will produce a piezoelectric effect, causing audio noise. Therefore, the communication noise of wireless charging under low load conditions is relatively large.

[0051] In order to solve the problem of large communication noise in wireless charging under low load conditions, the present disclosure can select the corresponding target communication capacitor based on the current charging parameters. Different communication capacitors have different capacitance values, and communication capacitors with different capacitance values ​​have different adjustment amplitudes for the ripple size of the communication signal. In this way, the target communication capacitor suitable for the current charging load can be selected according to the charging parameters that characterize the current charging load size. The ripple size of the communication signal can be adjusted by the target communication capacitor, which can reduce the communication noise of wireless charging under low load conditions.

[0052] In step S102, the target communication capacitor is used to communicate with the wireless charging transmitter.

[0053] The wireless charging transmitter may be, for example, a wireless charging base connected to a charging power source.

[0054] By adopting the above method, according to the charging parameters corresponding to the wireless charging receiving end, the target communication capacitor corresponding to the charging parameters is determined; wherein different charging parameters correspond to communication capacitors with different capacitances; the target communication capacitor is used to communicate with the wireless charging transmitting end. Since the charging parameters represent the size of the current charging load, the target communication capacitor corresponding to the charging parameters determined based on the charging parameters is also adapted to the current charging load, so that different communication capacitors can be selected for different load conditions to reduce communication noise and improve the user's charging experience.

[0055] In a possible embodiment of the present disclosure, the charging parameter includes a load current. Thus, in the process of executing step S101, the target communication capacitance corresponding to the load current can be determined.

[0056] Figure 2 is a flow chart of a communication method according to an exemplary embodiment. Figure 2 As shown, step S101 includes the following sub-steps:

[0057] In step S1011, if the load current is greater than or equal to the first current, the target communication capacitor is determined to be a preset communication capacitor having a first capacitance.

[0058] In one possible embodiment of the present disclosure, the preset communication capacitor may be two COM capacitors of different capacitances connected in parallel with each other in the wireless charging circuit. The preset communication capacitor may include, for example, a 10nF COM capacitor or a 33nF COM capacitor.

[0059] In one embodiment of the present disclosure, the first current may be, for example, a current of 3.5A (amperes), and the preset communication capacitor of the first capacitance may be a COM capacitor of 33nF. Thus, when it is determined that the load current is greater than or equal to 3.5A, the target communication capacitor may be determined to be a COM capacitor of 33nF.

[0060] In step S1012, if the load current is less than the first current and greater than or equal to the second current, the target communication capacitor is determined to be a preset communication capacitor having a second capacitance.

[0061] The first current is greater than the second current, and the first capacitance is greater than the second capacitance.

[0062] In a possible embodiment of the present disclosure, the second current may be, for example, a current of 2.2A (ampere), and the preset communication capacitor of the second capacitance may be a COM capacitor of 10nF. Thus, when it is determined that the load current is less than 3.5A and greater than or equal to 2.2A, the target communication capacitor may be determined to be a COM capacitor of 10nF.

[0063] As mentioned above, when wireless charging is performed, different charging loads will have different communication noise during the charging process. The communication noise is related to the ripple size of the communication signal. The larger the ripple of the communication signal, the larger the corresponding communication noise. However, if the ripple of the communication signal is large, it will affect the unpacking quality of the communication signal at the signal receiving end. Therefore, the ripple size of the communication signal after the communication capacitor adjusts the communication signal needs to comprehensively consider the unpacking quality of the communication signal at the signal receiving end and the size of the communication noise.

[0064] Generally, communication capacitors with different capacitance values ​​have different adjustment ranges for the ripple size of the communication signal, and the larger the capacitance value, the better the noise suppression ability. However, if the communication capacitor is connected in parallel in the wireless charging circuit, the smaller the capacitance value, the stronger the corresponding noise reduction ability. When the load current is greater than or equal to the first current, it can be regarded as the current charging load is large. Compared with the low load of wireless charging, the communication noise under high load is relatively weak, and the communication noise under high load is relatively strong. Therefore, under high load conditions, communication capacitors with higher capacitance values ​​can be selected for communication to ensure the unpacking quality of the communication signal at the signal receiving end. Under low load conditions, it is necessary to use communication capacitors with relatively low capacitance values ​​to achieve noise reduction. Therefore, in a possible embodiment of the present disclosure, when it is determined that the load current is greater than or equal to 3.5A (i.e., when the load current is higher), the target communication capacitance can be determined to be a COM capacitor of 33nF. When it is determined that the load current is less than 3.5A and greater than or equal to 2.2A, the target communication capacitance can be determined to be a COM capacitor of 10nF. This is only an example, and the present disclosure is not limited to this.

[0065] It should be noted that during wireless charging, in order to improve the charging efficiency, the charge pump can be turned on. Taking the scenario of wireless charging of a mobile phone as an example, for example, when the power of the mobile phone is less than the first preset power threshold (such as 60%) (for example, the power of the mobile phone is less than 60%, and the corresponding load current is greater than or equal to 2.2A), in order to improve the charging efficiency, the charge pump can be turned on and the charge pump can be controlled to operate in a 4:1 mode (in this mode, the corresponding input voltage to output voltage ratio is 4:1, and the input current to output current ratio is 1:4). When the power of the mobile phone is greater than the first preset power threshold (such as 60%) and less than the second preset power threshold (such as 80%), the working mode of the charge pump can be switched to a 2:1 mode. When the power of the mobile phone is greater than or equal to the second preset power threshold, if the charge pump is still turned on, it may cause a relatively high charging loss. Therefore, when the power of the mobile phone is greater than or equal to the second preset power threshold, the charge pump can be turned off.

[0066] Thus, in a possible embodiment, when it is determined that the charge pump operates in a 4:1 mode and the load current is above 3.5A, a 33nF COM capacitor can be used for wireless charging communication; when it is determined that the charge pump operates in a 4:1 mode and the load current is between 2.2A-3.5A, a 10nF COM capacitor can be used for wireless charging communication. This is only an example and the present disclosure is not limited to this.

[0067] In step S1013, if the load current is less than the second current, it is determined whether a charge pump is turned on in the current wireless charging circuit, and the charge pump is used to control the efficiency of wireless charging.

[0068] In step S1014, the target communication capacitance is determined according to a result of determining whether the charge pump in the wireless charging circuit is turned on.

[0069] In a possible embodiment of this step, when it is determined that the charge pump is not turned on in the wireless charging circuit, the target communication capacitor is determined to be a preset communication capacitor having the second capacitance.

[0070] When it is determined that the charge pump is not turned on in the wireless charging circuit, wireless charging is usually performed according to the standard charging protocol EPP. In this charging mode, if the load current is less than the second current, the preset communication capacitor with the second capacitance can be used as the target communication capacitor.

[0071] For example, when it is determined that the charge pump is not turned on in the wireless charging circuit, if it is determined that the current load current is less than 2.2A, and the charging mode is wireless charging according to the standard charging protocol EPP, a 10nF COM capacitor can be used as the target communication capacitor.

[0072] In another possible embodiment of this step, when it is determined that the charge pump is turned on in the wireless charging circuit, if the load current is greater than or equal to the third current, the target communication capacitor is determined to be a preset communication capacitor with the first capacitance; if the load current is less than the third current, the target communication capacitor is determined to be a preset communication capacitor with the first capacitance and a preset communication capacitor with the second capacitance.

[0073] The third current may be, for example, a current of 1.5A (ampere).

[0074] For example, when it is determined that the charge pump is turned on in the wireless charging loop and the charge pump operates in a 2-to-1 mode, if the load current is greater than or equal to 1.5A, a 33nF COM capacitor can be used as the target communication capacitor; if the load current is less than 1.5A, a 10nF COM capacitor and a 33nF COM capacitor can be used in parallel to form an equivalent 43nF COM capacitor as the target communication capacitor. This is only an example and the present disclosure is not limited to this.

[0075] In a possible embodiment of the present disclosure, the preset communication capacitor of the first capacitance and the preset communication capacitor of the second capacitance are connected in parallel to each other.

[0076] For example, Figure 3is a schematic diagram of a circuit architecture of wireless charging according to an exemplary embodiment. Figure 3 As shown, AC is an alternating current power supply, which is used to wirelessly charge the terminal after being connected to the wireless charging base. Figure 3 The circuit architecture except AC is integrated in the terminal to be charged (such as a mobile phone). Figure 3 As shown, in the wireless charging circuit, two COM capacitors (i.e., a 10nF COM capacitor and a 33nF COM capacitor) are arranged in parallel. The wireless charging base communicates with the subsequent load through the 10nF COM capacitor and the 33nF COM capacitor connected in parallel. The AC signal output by the COM capacitor passes through the rectification circuit of the wireless charging chip to obtain a rectified voltage (usually denoted as Vrect), and then passes through linear voltage regulation to obtain a stable voltage Vout. The voltage Vout can be used as the input voltage of the battery of the terminal to be charged, thereby realizing wireless charging of the terminal.

[0077] Based on Figure 3 In the process of implementing wireless charging in the wireless charging circuit architecture shown, a 10nF COM capacitor and / or a 33nF COM capacitor can be selected as the target communication capacitor based on the different load currents in the above embodiments, so that the ripple size of the communication signal can be adjusted through the target communication capacitor to ensure the communication quality and reduce the communication noise under the premise of good unpacking.

[0078] In another possible implementation of the present disclosure, the charging parameter may also include a rectified voltage during the wireless charging process, and the rectified voltage may be, for example, Figure 3 The AC signal output by the COM capacitor shown in the figure is passed through the rectifier circuit of the wireless charging chip to obtain a rectified voltage Vrect. In this way, during the execution of step S101, the target communication capacitor can be determined according to the load current and the rectified voltage.

[0079] For example, when it is determined that the load current is less than or equal to the third current and the rectified voltage is less than or equal to the first preset voltage threshold, a 10nF COM capacitor and a 33nF COM capacitor can be selected in parallel to form a 43nF COM capacitor as the target communication capacitor, and when it is determined that the load current is greater than the third current and the rectified voltage is less than or equal to the first preset voltage threshold, a 33nF COM capacitor can be selected as the target communication capacitor. The third current can be, for example, 1.5A, and the first voltage threshold can be, for example, 9V.

[0080] In another possible implementation of the present disclosure, the charging parameters may further include actual charging power. Thus, in the process of executing step S101, the target communication capacitor may be determined according to the load current, the rectified voltage and the actual charging power.

[0081] The preset power threshold corresponding to the actual charging power may include a first power threshold, a second power threshold, a third power threshold and a fourth power threshold, wherein the first power threshold is less than the second power threshold, the second power threshold is less than the third power threshold, and the third power threshold is less than the fourth power threshold. For example, the first power threshold may be 5W, the second power threshold may be 9W, the third power threshold may be 16W, and the fourth power threshold may be 50W. The preset voltage threshold corresponding to the rectified voltage may include a first voltage threshold and a second voltage threshold, and the first voltage threshold is less than the second voltage threshold. For example, the first voltage threshold may be 9V, and the second voltage threshold may be 15V.

[0082] Thus, for example, when it is determined that the rectified voltage Vrect is greater than 15V, the load current is between 2.2A-3.5A, and the actual charging power is less than or equal to 16W, a 10nF COM capacitor can be used as the target communication capacitor; when it is determined that the rectified voltage Vrect is greater than 15V, the load current is greater than 3.5A, and the actual charging power is greater than 16W and less than or equal to 50W, a 33nF COM capacitor can be used as the target communication capacitor. This is only an example and the present disclosure is not limited to this.

[0083] In another possible implementation of the present disclosure, the charging parameters may also include the actual charging power and the rectified voltage during the wireless charging process. Thus, during the execution of step S101, the target communication capacitor may be determined based on the actual charging power and the rectified voltage.

[0084] For example, when it is determined that the rectified voltage is within the preset voltage range and the actual charging power is within the preset power range, a 10nF COM capacitor can be used as the target communication capacitor. For example, the preset voltage range can be 9V-15V, and the preset power range can be 5W-9W.

[0085] By adopting the above method, according to the charging parameters corresponding to the wireless charging receiving end, the target communication capacitor corresponding to the charging parameters is determined; wherein different charging parameters correspond to communication capacitors with different capacitances; the target communication capacitor is used to communicate with the wireless charging transmitting end. Since the charging parameters represent the size of the current charging load, the target communication capacitor corresponding to the charging parameters determined based on the charging parameters is also adapted to the current charging load, so that different communication capacitors can be selected for different load conditions to reduce communication noise and improve the user's charging experience.
