[0001] The embodiments of the present application relate to the field of smart terminal technology, and specifically to a charging control method, an electronic device, and a computer-readable storage medium. Background Art

[0002] As the demand for fast charging increases, there are many types of chargers that support fast charging on the market, but different types of chargers may support different fast charging protocols. Electronic devices can usually support multiple fast charging protocols. Based on the differences in various fast charging protocols, electronic devices need to perform various fast charging protocol detections in different time periods during the protocol detection process. However, electronic devices poll various fast charging protocols in turn, and each fast charging protocol detection requires a certain amount of detection time, which makes the entire protocol detection process quite time-consuming, thus affecting the user experience. Summary of the invention

[0003] The embodiments of the present application provide a charging control method, an electronic device, and a computer-readable storage medium, which aim to solve the problem that the detection process of multiple fast charging protocols is time-consuming.

[0004] The first aspect of the embodiment of the present application provides a charging control method, which is applied to an electronic device, and the electronic device supports multiple fast charging protocols, including a private protocol and a UFCS protocol. The charging control method includes: based on the electronic device being connected to the charger, and the charging interface type of the charger being a dedicated charging interface, performing connectivity detection and setting a connectivity detection flag. Among them, the connectivity detection is used to test whether the charger supports the private protocol, the private protocol includes a super charging protocol and a fast charging protocol, the charging mode specified by the super charging protocol is a super fast charging mode, and the charging mode specified by the fast charging protocol is a discrete voltage regulation mode. The connectivity detection flag includes a detection success flag or a detection failure flag. Based on the connectivity detection flag being a detection success flag, a super charging protocol detection is performed. The super charging protocol detection is used to determine whether the charger supports the super charging protocol. Based on the connectivity detection flag being a detection success flag, and the super charging protocol detection fails, a fast charging protocol detection is performed. The fast charging protocol detection is used to determine whether the charger supports the fast charging protocol. Based on the completion of the fast charging protocol detection, a UFCS protocol detection is performed. The UFCS protocol detection is used to determine whether the charger supports the UFCS protocol, and the charging mode specified by the UFCS protocol is the super fast charging mode. Based on successful UFCS protocol detection, the charging mode of the electronic device is set to super fast charging mode.

[0005] In this embodiment, various fast charging protocol detections are performed in the order of priority of private protocols. Since the super charging protocol and the fast charging protocol can share the connectivity detection results, the connectivity detection results can be obtained by querying the connectivity detection identifier during the fast charging protocol detection, without the need to perform the connectivity detection again, thereby reducing the number of connectivity detections, thereby reducing the protocol detection time, and thus improving the charging efficiency and user experience. In addition, since the charging method specified by the fast charging protocol is different from the charging method specified by the super charging protocol / UFCS protocol, and the maximum charging power supported by the fast charging protocol is less than the maximum charging power supported by the UFCS protocol, after the fast charging protocol detection, regardless of whether the fast charging protocol detection succeeds or fails, the UFCS protocol detection must be performed, which is conducive to ensuring that the electronic device is charged at the maximum charging power adapted to the charger.

[0006] In one embodiment, the charging control method further includes: based on the fast charging protocol detection being successful and the UFCS protocol detection being failed, setting the charging mode of the electronic device to a discrete voltage regulation mode.

[0007] In another embodiment, the charging control method further includes: based on the failure of the fast charging protocol detection and the failure of the UFCS protocol detection, setting the charging mode of the electronic device to the normal charging mode.

[0008] In another embodiment, the charging control method further includes: based on successful detection of the super charging protocol, setting the charging mode of the electronic device to a super fast charging mode.

[0009] In another embodiment, the charging control method further includes: setting a super fast charge effective value based on a successful super charging protocol detection or a successful UFCS protocol detection. The super fast charge effective value is used to indicate whether the charger supports the super fast charge mode. Based on the super fast charge effective value being a non-null value, setting the charging mode of the electronic device to the super fast charge mode.

[0010] In another embodiment, the charging control method further includes: setting a fast charging protocol support flag based on the fast charging protocol detection success, wherein the fast charging protocol support flag is used to indicate that the charger supports the discrete voltage regulation mode.

[0011] In another embodiment, the charging control method further includes: based on the super fast charge effective value being a null value and the fast charge protocol support flag being non-null, setting the charging mode of the electronic device to a discrete voltage regulation mode.

[0012] In another embodiment, the charging control method further includes: based on the super fast charging effective value being a null value and the fast charging protocol support flag being null, setting the charging mode of the electronic device to a normal charging mode.

[0013] In another embodiment, the charging control method further includes: based on the connectivity detection flag being a detection failure flag, performing UFCS protocol detection.

[0014] In another embodiment, the multiple fast charging protocols also include the PPS protocol, and the charging control method further includes: based on the electronic device being connected to the charger and determining that the charging interface type of the charger is a dedicated charging interface, performing PPS protocol detection. The PPS protocol detection is used to determine whether the charger supports the PPS protocol.

[0015] In another embodiment, the charging control method further includes: setting a super fast charging effective value based on successful PPS protocol detection.

[0016] In another embodiment, the charging control method further includes: based on the failure of the PPS protocol detection and the completion of the fast charging protocol detection, performing the UFCS protocol detection.

[0024] It should be noted that the method disclosed in the embodiments of the present application or the method shown in the flowchart includes one or more steps for implementing the method. Without departing from the scope of the claims, the execution order of multiple steps can be interchangeable with each other, and some of the steps can also be deleted.

[0025] The electronic devices involved in the embodiments of the present application may include, but are not limited to, smart phones, tablet computers, personal computers (PCs), e-book readers, workstations, servers, personal digital assistants (PDAs), portable multimedia players (PMPs), mobile medical devices, cameras, and wearable devices such as smart watches, smart bracelets, and smart glasses.

[0026] With the increasing demand for fast charging, there are many types of chargers that support fast charging on the market, but different types of chargers may support different fast charging protocols. Electronic devices can usually support multiple fast charging protocols, such as the Universal Fast Charging Specification (UFCS) protocol, the Programmable Power Supply (PPS) protocol, and private protocols. Private protocols are fast charging protocols defined by each electronic device manufacturer, such as the Fast Charge Protocol (FCP), the Super Charge Protocol (SCP), etc. After the electronic device is connected to the charger, it will perform multiple fast charging protocol detections to determine the fast charging protocol supported by the charger, and then select the charging mode that is compatible with the charger.

[0027] Based on the differences between various fast charging protocols, electronic devices need to perform various fast charging protocol detections in different time periods during the protocol detection process. For example, when electronic devices detect UFCS protocols and private protocols, they use the data positive (Data Positive, DP) signal line and data negative (Data Negative, DN) signal line of the Universal Serial Bus (USB) data line to communicate with the charger. However, private protocol detection requires disconnecting the DP and DN signal lines, and UFCS protocol detection requires short-circuiting the DP and DN signal lines. Therefore, the UFCS protocol and private protocol cannot be detected in parallel. And because different fast charging protocols support different fast charging powers, for example, the maximum charging power supported by the UFCS protocol is usually 33W, the maximum charging power supported by FCP is usually 18W, and the maximum charging power supported by SCP can be higher than 100W. Therefore, various fast charging protocol detections are usually detected in order from large to small according to the maximum charging power supported by the fast charging protocol.

[0028] For example, see Figure 1 In step S101, based on the electronic device being connected to the charger and the DP and DN signal lines being in a short-circuited state, the electronic device performs a Battery Charging specification revision 1.2 (BC1.2) test. The BC1.2 test is used to determine the type of charging interface of the charger. The charging interface type may include, but is not limited to, a dedicated charging port (DCP), a standard downstream port (SDP), and a USB interface. When the charger detects that an electronic device is connected, it short-circuits the DP and DN signal lines.

[0029] In step S102, based on the charging interface type of the charger being DCP, the electronic device performs a High Voltage Dedicated Charging Port (HVDCP) detection, which is used to control the charger to switch the DP and DN signal lines from a short-circuited state to a disconnected state.

[0030] In step S103, based on the DP and DN signal lines being in a disconnected state, the electronic device performs SCP detection. SCP detection is used to determine whether the charger supports SCP. If the SCP detection succeeds, it is determined that the charger supports SCP. If the SCP detection fails, it is determined that the charger does not support SCP.

[0031] In step S104, based on the failure of the SCP detection and the DP and DN signal lines being in a short-circuited state, the electronic device performs a UFCS protocol detection. The UFCS protocol detection is used to determine whether the charger supports the UFCS protocol. If the UFCS protocol detection is successful, it is determined that the charger supports the UFCS protocol. If the UFCS protocol detection fails, it is determined that the charger does not support the UFCS protocol. When the SCP detection fails, the electronic device can feedback the SCP detection failure information to the charger. Based on the SCP detection failure information, the charger short-circuits the DP and DN signal lines.

[0032] In step S105 , based on the failure of the UFCS protocol detection, the electronic device performs HVDCP detection.

[0033] In step S106, based on the DP and DN signal lines being in a disconnected state, the electronic device performs FCP detection. FCP detection is used to determine whether the charger supports FCP. If the FCP detection succeeds, it is determined that the charger supports FCP. If the FCP detection fails, it is determined that the charger does not support FCP.

[0034] In step S107, after performing the BC1.2 detection, the electronic device performs a PPS protocol detection based on the charging interface type of the charger being DCP. The PPS protocol detection is used to determine whether the charger supports the PPS protocol. If the PPS protocol detection is successful, it is determined that the charger supports the PPS protocol. If the PPS protocol detection fails, it is determined that the charger does not support the PPS protocol. Since the PPS protocol detection uses the Configuration Channel (CC) line of the USB data line, it does not conflict with the UFCS protocol / SCP / FCP detection in timing, so the PPS protocol can be detected in parallel with the UFCS protocol / SCP / FCP.

[0035] In step S108, based on the success of the FCP detection and the failure of the PPS protocol detection, the electronic device sets the charging mode to the discrete voltage regulation mode.

[0036] In the above embodiment, when the electronic device executes the above-mentioned various fast charging protocol detections, it can switch to the protocol signal and interface voltage corresponding to the current fast charging protocol through the internal processor, and record the response of the charger to the protocol signal and interface voltage, and determine whether the current fast charging protocol is detected successfully or failed based on the recorded response.

[0037] For each fast charging protocol detection, a retry threshold can be set. When a fast charging protocol detection fails, the electronic device re-executes the fast charging protocol detection until the number of re-executions reaches the retry threshold, and then the electronic device determines that the charger does not support the fast charging protocol. For example, the retry threshold for each fast charging protocol detection is set to 4. When testing a charger that supports FCP, the electronic device performs Figure 1 The multiple fast charging protocol detection strategies shown, the entire protocol detection process takes about 8s.

[0038] It is understandable that the electronic device polls various fast charging protocols in sequence, and each fast charging protocol detection requires a certain detection time, resulting in the entire protocol detection process being quite time-consuming, thus affecting the user experience.

[0039] Based on this, the embodiments of the present application provide a charging control method, an electronic device, and a computer-readable storage medium, which aim to solve the problem that the detection process of multiple fast charging protocols is time-consuming.

[0040] Figure 2 This is a flow chart of a charging control method provided by an embodiment of the present application.

[0041] In this embodiment, the charging control method is applied to an electronic device, and the electronic device supports multiple fast charging protocols, including a private protocol, a UFCS protocol, and a PPS protocol, and the private protocol includes SCP and FCP. The electronic device can be connected to a charger via a charging cable, and the charging cable includes a DP, DN signal line, and a CC line.

[0042] See also Figure 2 , the charging control method comprises the following steps:

[0043] S201, based on the electronic device being connected to the charger and the DP and DN signal lines being in a short-circuited state, a BC1.2 detection is performed.

[0044] Among them, BC1.2 detection is used to determine the charging interface type of the charger.

[0045] S202: Based on the charging interface type of the charger being DCP, perform HVDCP detection.

[0046] Among them, HVDCP detection is used to control the charger to switch the DP and DN signal lines from a short-circuited state to a disconnected state.

[0047] S203, based on the DP and DN signal lines being in a disconnected state, performing a connectivity detection and setting a connectivity detection flag.

[0048] In this embodiment, the connectivity test is used to test whether the charger supports the private protocol. The connectivity test flag is used to indicate the connectivity test result, and the connectivity test result includes a successful test or a failed test. Accordingly, the connectivity test flag includes a successful test flag or a failed test flag. If the connectivity test is successful, it is determined that the charger may support SCP or FCP, and the connectivity test flag is set to a successful test flag. If the connectivity test fails, it is determined that the charger does not support SCP and FCP, and the connectivity test flag is set to a failed test flag.

[0049] Exemplarily, connectivity detection includes an internet packet detector (Packet internet groper, Ping) detection. The Ping detection process may include: the electronic device generates a Ping data packet of a preset baud rate through an internal processor, and transmits the Ping data packet to the charger through the DN signal line. After receiving the Ping data packet, the charger generates an Acknowledgement (ACK) data packet and transmits the ACK data packet to the electronic device through the DP signal line. If the electronic device receives the ACK data packet, it confirms that the Ping detection is successful and sets the Ping detection flag to the detection success flag, such as ping_success_flag=true. If the electronic device does not receive the ACK data packet, it confirms that the Ping detection fails and sets the Ping detection flag to the detection failure flag, such as ping_success_flag=false.

[0050] S204: Determine whether the connectivity detection is successful.

[0051] If the connectivity check succeeds, steps S205 to S206 are executed; if the connectivity check fails, step S212 is executed.

[0052] S205: Based on the connectivity detection flag being a detection success flag, perform SCP detection.

[0053] Among them, SCP detection is used to determine whether the charger supports SCP.

[0054] S206: Determine whether the SCP detection is successful.

[0055] If the SCP detection succeeds, step S207 is executed; if the SCP detection fails, step S208 is executed.

[0056] S207, based on successful SCP detection, setting the super fast charge effective value.

[0057] In this embodiment, the super fast charge effective value is used to indicate whether the charger supports the super fast charge mode. If the SCP detection is successful, it is determined that the charger supports SCP, and the super fast charge effective value is set to a preset value. Among them, the preset value can be set as needed. For example, the preset value can be set to valid num++, that is, the original value plus 1. If the SCP detection fails, it is determined that the charger does not support SCP, and the super fast charge effective value is 0 or null.

[0058] After executing step S207, step S217 may be executed.

[0059] S208: Based on the connectivity detection flag being a detection success flag and the SCP detection failing, perform FCP detection.

[0060] Among them, FCP detection is used to determine whether the charger supports FCP.

[0061] In this embodiment, since both SCP and FCP detections need to disconnect the DP and DN signal lines, SCP and FCP detections can share the results of HVDCP detection and connectivity detection, thereby reducing the number of times HVDCP detection and connectivity detection are performed, thereby reducing the protocol detection time.

[0062] S209, determining whether the FCP detection is successful.

[0063] If the FCP detection succeeds, step S210 is executed; if the FCP detection fails, step S212 is executed.

[0064] S210: Based on the successful FCP detection, an FCP support flag is set.

[0065] In this embodiment, the FCP support flag is used to indicate that the charger supports the discrete voltage regulation mode. If the FCP detection is successful, it is determined that the charger supports FCP, and the FCP support flag is set to non-empty, for example, the FCP support flag is set to support_fcp_flag = true. If the FCP detection fails, it is determined that the charger does not support FCP, and the FCP support flag is empty.

[0066] S211: Based on the charging interface type of the charger being DCP, perform PPS protocol detection.

[0067] In this embodiment, after executing step S201, step S211 may be executed.

[0068] Among them, the PPS protocol detection is used to determine whether the charger supports the PPS protocol.

[0069] S212, determining whether the PPS protocol detection is successful.

[0070] If the PPS protocol detection is successful, execute step S213; if the PPS protocol detection fails, execute step S214.

[0071] S213, based on successful detection of the PPS protocol, set the super fast charge effective value.

[0072] In this embodiment, if the PPS protocol detection is successful, it is determined that the charger supports the PPS protocol, and the super fast charge effective value is set to a preset value. If the PPS protocol detection fails, it is determined that the charger does not support the PPS protocol, and the super fast charge effective value is 0 or null.

[0073] After executing step S213, step S217 may be executed.

[0074] S214: Based on the failure of the PPS protocol detection and the short-circuited state of the DP and DN signal lines, the UFCS protocol detection is performed.

[0075] In this embodiment, since UFCS protocol detection requires short-circuiting the DP and DN signal lines, the electronic device can feedback PPS protocol detection failure information to the charger when the PPS protocol detection fails. The charger short-circuits the DP and DN signal lines based on the PPS protocol detection failure information.

[0076] Among them, the UFCS protocol detection is used to determine whether the charger supports the UFCS protocol. Since the DP and DN signal lines are switched from the disconnected state to the shorted state, the UFCS protocol detection includes the UFCS connectivity detection. The process of the UFCS connectivity detection is roughly the same as the process of the connectivity detection in the above step S203, and will not be repeated here.

[0077] S215, determining whether the UFCS protocol detection is successful.

[0078] If the UFCS protocol detection succeeds, step S216 is executed; if the UFCS protocol detection fails, step S220 is executed.

[0079] S216: The UFCS protocol detection is successful and the super fast charge effective value is set.

[0080] In this embodiment, if the UFCS protocol detection is successful, it is determined that the charger supports the UFCS protocol, and the super fast charge effective value is set to a preset value. If the UFCS protocol detection fails, it is determined that the charger does not support the UFCS protocol, and the super fast charge effective value is 0 or null.

[0081] After executing step S216, step S217 may be executed.

[0082] S217, determine whether the super fast charge effective value is a non-null value.

[0083] If the super fast charge effective value is a non-null value, execute step S218; if the super fast charge effective value is a null value, execute step S219.

[0084] S218, setting the charging mode to super fast charging mode.

[0085] In this embodiment, when the electronic device determines that the charger supports any one of the fast charging protocols of SCP, PPS or UFCS, the super fast charge effective value is a non-null value, and the charging mode can be set to the super fast charge mode. In the super fast charge mode, the electronic device can use the super fast charge state machine to perform continuous voltage regulation control for charging.

[0086] S219, determining whether the FCP support flag is empty.

[0087] If the FCP support flag is empty, execute step S220; if the FCP support flag is not empty, execute step S221.

[0088] S220, setting the charging mode to the normal charging mode.

[0089] In this embodiment, when the electronic device determines that the charger does not support SCP, FCP, PPS and UFCS protocols, the super fast charging effective value is null and the FCP support flag is null, and the charging mode can be set to normal charging mode, such as 5V DC charging.

[0090] S221, setting the charging mode to discrete voltage regulation mode.

[0091] In this embodiment, when the electronic device determines that the charger does not support SCP, PPS and UFCS protocols, but supports FCP, the super fast charging effective value is a null value, and the FCP support flag is non-null, and the charging mode can be set to a discrete voltage regulation mode, such as 9V / 5V discrete voltage regulation control.

[0092] It can be understood that various fast charging protocol detections are in the order of priority of private protocols. The detection order of SCP, PPS protocol and UFCS protocol is the order from large to small of the maximum charging power supported by the fast charging protocol. Since the charging method specified by FCP is different from the charging method specified by SCP / UFCS protocol, and the maximum charging power supported by FCP is less than the maximum charging power supported by UFCS protocol, after FCP detection, regardless of whether the electronic device determines that the charger supports FCP, UFCS protocol detection must be performed, which is conducive to ensuring that the electronic device is charged at the maximum charging power adapted by the charger.

[0093] In other embodiments, SCP and FCP may be replaced with other private protocols with similar charging methods, such as VOOC protocol, SuperVOOC protocol, FlashCharge protocol, Warp protocol, and Dash protocol.

[0094] It can be understood that for the above-mentioned various fast charging protocol detections, a retry threshold can be set. For example, the retry threshold for each fast charging protocol detection is set to 4. When testing a charger that supports FCP, the electronic device executes the charging control method of this embodiment, and the entire protocol detection process takes about 3 seconds. Since SCP and FCP detection can share the results of HVDCP detection and connectivity detection, the number of times HVDCP detection and connectivity detection are performed can be reduced. Therefore, compared to Figure 1 The multiple fast charging protocol detection strategies shown, executing the charging control method of this embodiment can significantly reduce the protocol detection time, thereby improving the charging efficiency.

[0095] Figure 3 This is a flow chart of a charging control method provided in another embodiment of the present application.

[0096] Compared to Figure 2 In the charging control method shown, in this embodiment, the multiple fast charging protocols include a private protocol and a UFCS protocol. The private protocol includes a super charging protocol and a fast charging protocol. The charging mode specified by the super charging protocol is a super fast charging mode, and the charging mode specified by the fast charging protocol is a discrete voltage regulation mode. The maximum charging power specified by the super charging protocol / UFCS protocol is greater than the maximum charging power specified by the fast charging protocol.

[0097] See also Figure 3 , the charging control method comprises the following steps:

[0098] S301, based on the electronic device being connected to the charger and the charging interface type of the charger being DCP, performing connectivity detection and setting a connectivity detection flag.

[0099] The connectivity test is used to test whether the charger supports the private protocol. The connectivity test flag includes a successful test flag or a failed test flag.

[0100] S302: Determine whether the connectivity detection is successful.

[0101] If the connectivity check succeeds, step S303 is executed; if the connectivity check fails, step S306 is executed.

[0102] S303, executing super charging protocol detection.

[0103] Among them, the super charging protocol detection is used to determine whether the charger supports the super charging protocol.

[0104] S304, determining whether the super charging protocol detection is successful.

[0105] If the super charging protocol detection is successful, execute step S309; ​​if the super charging protocol detection fails, execute step S305.

[0106] S305: Based on the connectivity detection flag being a detection success flag, perform a fast charging protocol detection.

[0107] Among them, the fast charging protocol detection is used to determine whether the charger supports the fast charging protocol.

[0108] S306, executing UFCS protocol detection.

[0109] Among them, UFCS protocol detection is used to determine whether the charger supports the UFCS protocol. The charging mode specified by the UFCS protocol is the super fast charging mode.

[0110] In this embodiment, since the private protocol detection needs to disconnect the DP and DN signal lines, the UFCS protocol detection needs to short-circuit the DP and DN signal lines. Therefore, the UFCS protocol detection cannot share the connectivity detection result of the private protocol. The UFCS protocol detection includes the UFCS connectivity detection.

[0111] S307, determining whether the UFCS protocol detection is successful.

[0112] If the UFCS protocol detection succeeds, execute step S309; ​​if the UFCS protocol detection fails, execute step S308.

[0113] S308, determining whether the fast charging protocol detection is successful.

[0114] If the fast charging protocol detection is successful, step S310 is executed; if the fast charging protocol detection fails, step S311 is executed.

[0115] S309, setting the charging mode of the electronic device to the super fast charging mode.

[0116] S310, setting the charging mode of the electronic device to a discrete voltage regulation mode.

[0117] S311, setting the charging mode of the electronic device to a normal charging mode.

[0118] In this embodiment, various fast charging protocol detections are performed in the order of priority of private protocols. Since the super charging protocol and the fast charging protocol can share the connectivity detection results, the connectivity detection results can be obtained by querying the connectivity detection identifier during the fast charging protocol detection, without the need to perform the connectivity detection again, thereby reducing the number of connectivity detections, thereby reducing the protocol detection time, and thus improving the charging efficiency and user experience. In addition, since the charging method specified by the fast charging protocol is different from the charging method specified by the super charging protocol / UFCS protocol, and the maximum charging power supported by the fast charging protocol is less than the maximum charging power supported by the UFCS protocol, after the fast charging protocol detection, regardless of whether the fast charging protocol detection succeeds or fails, the UFCS protocol detection must be performed, which is conducive to ensuring that the electronic device is charged at the maximum charging power adapted to the charger.
