[0055] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0056] The charging control method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. When the electronic device 102 is electrically connected to the external power adapter 104, the first charging parameter sent by the power adapter 104 is obtained; the first charging parameter is the charging parameter actually output by the power adapter 104; if the first charging parameter does not meet the preset charging condition, the third charging parameter is determined based on the first charging parameter and the preset second charging parameter; wherein the second charging parameter is the charging parameter of the target for charging the electronic device 102 through the power adapter 104; the third charging parameter is sent to the power adapter 104 to instruct the power adapter 104 to adjust the charging parameter output by the power adapter based on the third charging parameter.

[0057] The electronic device 102 may be a terminal or a server; the terminal may be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, IoT devices, and portable wearable devices; IoT devices may be smart speakers, smart TVs, smart air conditioners, smart vehicle-mounted devices, smart cars, etc. Portable wearable devices may be smart watches, smart bracelets, head-mounted devices, etc. The server may be implemented as an independent server or a server cluster consisting of multiple servers.

[0058] The power adapter 104 is a power supply conversion device for small portable electronic devices and electronic appliances, and is generally composed of components such as a housing, a transformer, an inductor, a capacitor, a control IC, and a PCB board. The power adapter can be a fixed power adapter or a mobile power adapter. A fixed power adapter can be a power supply and a charging cable fixed to the wall, and a mobile power adapter can be a mobile power bank, etc.

[0059] The electronic device and the power adapter are electrically connected, either through a physical charging cable or a wireless charging connection.

[0060] In one embodiment, Figure 2As shown, a charging control method is provided, which is applied to Figure 1 The electronic device in the example is used to illustrate, and the following steps are included:

[0061] Step S202: when the electronic device is electrically connected to the power adapter, obtain a first charging parameter sent by the power adapter; the first charging parameter is a charging parameter actually output by the power adapter.

[0062] Optionally, the first charging parameter includes a first voltage parameter or a first current parameter. The first voltage parameter is a voltage parameter actually output by the power adapter, and the first current parameter is a current parameter actually output by the power adapter. Optionally, the first charging parameter is obtained by the power adapter sampling the charging circuit, and is sent to the electronic device through the connection between the adapter and the electronic device, so that the electronic device can obtain the first charging parameter.

[0063] Optionally, when the electronic device and the power adapter are electrically connected, the electronic device and the power adapter communicate using the Universal Fast Charging Specification (UFCS) so that the electronic device obtains the current first charging parameter of the power adapter. The Universal Fast Charging Specification (UFCS) is also the terminal fusion fast charging technology.

[0064] Optionally, when the electronic device and the power adapter are electrically connected, if the electronic device identifies the dedicated charging port (DCP) of the power adapter, a pulse string is sent to the power adapter; if the electronic device detects a response signal from the power adapter to the pulse string, a ping control command is sent to the power adapter; if the electronic device detects a response signal from the power adapter to the ping control command, the electronic device and the power adapter use a fused fast charging protocol to obtain the first charging parameter sent by the power adapter.

[0065] Among them, the electronic device sends a pulse string to the power adapter, that is, the electronic device and the power adapter shake hands; if the power adapter responds to the pulse string, it means that the power adapter is a UFCS adapter, and the power adapter supports the fusion fast charging protocol.

[0066] The ping control command is used to determine the baud rate of communication between the electronic device and the power adapter. It is understandable that the dedicated charging port of the power adapter is of Type-C type; the communication physical hardware that integrates the fast charging protocol uses D+D- to achieve transmission and reception, so the electronic device and the power adapter need to negotiate the baud rate of communication. Exemplary baud rates are 115200, 57600, 38400, and two pins for data.

[0067] Optionally, when the electronic device sends a Ping control command to the power adapter multiple times (at least 5 times) at a preset baud rate but does not receive a response signal from the power adapter, the electronic device switches the baud rate of the preset gear to a baud rate of another gear and resends the Ping control command to the power adapter at the baud rate of another gear until a response signal from the power adapter is received.

[0068] The response signal of the power adapter to the pulse train, or the response signal of the power adapter to the ping control command, may be an ACK feedback signal or an NCK feedback signal, etc., but is not limited thereto.

[0069] Optionally, the electronic device sends a pulse string to the power adapter so that the power adapter responds to the pulse string and switches to UFCS mode; the electronic device detects the response signal of the power adapter to the pulse string, and sends a ping control command to the power adapter, so that the power adapter responds to the ping control command in UFCS mode; when the electronic device detects the response signal of the power adapter to the ping control command, it determines that the electronic device and the power adapter use a fused fast charging protocol, and obtains the first charging parameter currently sent by the power adapter.

[0070] It is understandable that the electronic device first sends a pulse string and then sends a ping control command, so that the power adapter can switch to the UFCS mode based on the pulse string and respond to the ping control command in the UFCS mode.

[0071] Optionally, the dedicated charging port of the power adapter is of Type-C type; the electronic device recognizes the dedicated charging port of the power adapter, in which D+D- are connected together, and the electronic device sends a string of pulses to the power adapter through D- and then pulls down the level of D-; if the power adapter is a UFCS adapter, it responds to the pulse string, that is, it pulls up the level of D+; if the power adapter is not a UFCS adapter, it does not respond, that is, it does not pull up the level of D+; if the electronic device detects a response signal that the level of D+ is pulled up, it sends a ping control command to the power adapter.

[0072] Optionally, if the electronic device does not detect the power adapter's response to the pulse train, or the electronic device does not detect the power adapter's response to the ping control command, the electronic device and the power adapter are charged using other charging protocols besides the fused fast charging protocol.

[0073] Optionally, the electronic device obtains the current first charging parameter of the power adapter, including: the electronic device sends a charging parameter request command (protocol interaction code) to the power adapter to instruct the power adapter to obtain the current first charging parameter according to the charging parameter request command, and send the first charging parameter to the electronic device; the electronic device obtains the first charging parameter sent by the power adapter.

[0074] Optionally, the electronic device sends a charging parameter request command to the power adapter to instruct the power adapter to return a confirmation control command to the electronic device, and obtains the current first charging parameter according to the charging parameter request command, and sends the first charging parameter to the electronic device; the electronic device responds to the confirmation control command, starts a timer, and receives the first charging parameter sent by the power adapter within a preset timing duration of the timer.

[0075] If the first charging parameter sent by the power adapter is not received within the preset timing duration of the timer or the reception of the first charging parameter fails, the process returns to the step of sending the charging parameter request command to the power adapter again until the electronic device sends the charging parameter request command more than the preset number of times and fails to receive the first charging parameter sent by the power adapter, stops sending the charging parameter request command, and switches to other charging protocols for charging.

[0076] The preset number of times and the preset timing duration can be set as needed. For example, the preset number of times is 3 times, and the preset timing duration is 300 milliseconds. The electronic device fails to receive the first charging parameter, that is, the electronic device waits for a timeout. The charging parameter request command can be a get source info command packet, and the confirmation control command can be an ack control command.

[0077] Other charging protocols may include SVOOC (SUPERVOOC) fast charging protocol, QC (Quick Charge) fast charging protocol, or PPS (Programmable Power Supply, a fast charging technical specification) fast charging protocol.

[0078] It can be understood that if the electronic device sends a charging parameter request command more than a preset number of times and does not receive the first charging parameter sent by the power adapter, it indicates that there is a communication problem in the communication link between the electronic device and the power adapter, and it is necessary to switch the fused fast charging protocol to other charging protocols for charging.

[0079] Step S204: if the first charging parameter does not meet the preset charging condition, determine a third charging parameter based on the first charging parameter and the preset second charging parameter; wherein the second charging parameter is a charging parameter of the target for charging the electronic device through the power adapter.

[0080] The preset charging condition is a preset condition for determining whether the first charging parameter of the power adapter needs to be adjusted. The preset charging condition may include a preset voltage condition or a preset current condition.

[0081] Optionally, the preset charging condition may include one of the following: a first voltage parameter is greater than or equal to a second voltage parameter of a preset power adapter output to a battery in an electronic device, a first current parameter is less than a second current parameter of a preset power adapter output to a battery in an electronic device, or the first current parameter matches the battery voltage of the electronic device, but is not limited thereto.

[0082] Furthermore, the preset voltage condition may include a first voltage parameter greater than or equal to a second voltage parameter of a preset power adapter output to a battery in an electronic device, and the absolute value of the difference between the first voltage parameter and the second voltage parameter is less than or equal to a first preset threshold value; the preset current condition may include a first current parameter less than a second current parameter of a preset power adapter output to a battery in an electronic device, and the absolute value of the difference is less than or equal to a second preset threshold value.

[0083] Optionally, the preset second charging parameter matches the battery parameter of the electronic device. Optionally, the second charging parameter may include a second voltage parameter or a second current parameter. The second voltage parameter is a voltage parameter of the target of charging the electronic device through the power adapter, and the second current parameter is a current parameter of the target of charging the electronic device through the power adapter.

[0084] It is understandable that the power adapter charges the battery in the electronic device, and the charging parameters of the target of the power adapter charging the electronic device need to meet certain conditions, such as the voltage output by the power adapter to the battery in the electronic device is greater than the battery voltage to avoid current backflow to the power adapter, such as the current output by the power adapter to the battery in the electronic device needs to match the battery voltage or battery power to avoid damage to the battery, so the electronic device presets the second charging parameter output by the power adapter to the battery in the electronic device to match the battery parameter of the electronic device. Among them, the battery parameter of the electronic device may include the battery voltage, battery power or battery capacity of the electronic device, etc., but is not limited to this.

[0085] The third charging parameter is a charging parameter that the electronic device requests the power adapter to output. The third charging parameter may include a third voltage parameter or a third current parameter.

[0086] It is understandable that there is a certain loss when the power output of the power adapter is transmitted to the battery in the electronic device. Therefore, based on the first charging parameter and the preset second charging parameter, the third charging parameter is determined to instruct the power adapter to make adjustments based on the third charging parameter.

[0087] Optionally, the electronic device detects whether a first charging parameter meets a preset charging condition; if the first charging parameter does not meet the preset charging condition, the electronic device obtains a preset second charging parameter, and determines a third charging parameter based on the first charging parameter and the second charging parameter; if the first charging parameter meets the preset charging condition, it detects whether the second charging parameter changes, and if so, returns to execute the step of obtaining the first charging parameter sent by the power adapter.

[0088] Optionally, the electronic device detects whether the first charging parameter meets the preset charging condition, including: the electronic device detects whether the first charging parameter meets the preset charging condition based on the first charging parameter and the second charging parameter. Further, the electronic device determines the magnitude relationship and the absolute value of the difference between the first charging parameter and the second charging parameter; based on the magnitude relationship and the absolute value of the difference, determines whether the first charging parameter meets the preset charging condition.

[0089] Optionally, the electronic device determines a difference between the first charging parameter and the second charging parameter, and determines a third charging parameter corresponding to the difference from a correspondence between a preset difference and a third charging parameter.

[0090] Step S206: Send the third charging parameter to the power adapter to instruct the power adapter to adjust the charging parameter output by the power adapter based on the third charging parameter.

[0091] Optionally, the electronic device sends a third charging parameter to the power adapter, and after a preset time period, re-executes the step of obtaining the first charging parameter sent by the power adapter, and the third charging parameter is used to instruct the power adapter to adjust the charging parameter output by the power adapter based on the third charging parameter within the preset time period.

[0092] The preset duration can be set as required. For example, the preset duration is 20 milliseconds.

[0093] It is understandable that the power adapter may not be able to directly adjust the first charging parameter to the third charging parameter within the preset time. Therefore, the power adapter adjusts the first charging parameter based on the third charging parameter within the preset time. It may directly adjust the first charging parameter to the third charging parameter, or it may adjust the first charging parameter to an intermediate charging parameter; the intermediate charging parameter is less than the third charging parameter and greater than the first charging parameter.

[0094] It should be noted that even if the power adapter adjusts the first charging parameter to the third charging parameter within the preset time, the new current first charging parameter may not necessarily meet the preset charging conditions. It is necessary to re-acquire the first charging parameter sent by the power adapter and determine whether the new first charging parameter meets the preset charging conditions.

[0095] Exemplarily, the first voltage parameter = 10V (volts), the second voltage parameter of the preset power adapter output to the battery in the electronic device = 4V, and the preset voltage condition is that the first voltage parameter is greater than the second voltage parameter, and the difference between the first voltage parameter and the second voltage parameter is less than 300mv (millivolts); then, the first voltage parameter is 6V greater than the second voltage parameter, and does not meet the preset charging condition, and the step value corresponding to 6V is determined to be 5V, then the first charging parameter minus the step value is obtained to obtain a third voltage parameter of 5V, then even if the power adapter adjusts the first voltage parameter from 10V to 5V within the preset time, the new first voltage parameter 5V is still 1V greater than the second voltage parameter, and does not meet the preset voltage condition, so it is necessary to re-acquire the first voltage parameter sent by the power adapter and determine whether the new first voltage parameter meets the preset voltage condition.

[0096] In the above-mentioned charging control method, when the electronic device and the power adapter are electrically connected, and when the electronic device and the external power adapter are electrically connected, the electronic device obtains the first charging parameter sent by the power adapter, and the first charging parameter is the charging parameter actually output by the power adapter, thereby avoiding data deviation caused by taking the charging parameter recorded by the software as the actual charging parameter; if the first charging parameter does not meet the preset charging condition, a third charging parameter is determined based on the first charging parameter and the preset second charging parameter, and the second charging parameter is the charging parameter of the target for charging the electronic device through the power adapter, and a more accurate third charging parameter can be determined, so that the third charging parameter is sent to the power adapter, and the power adapter adjusts the charging parameter output by the power adapter based on the more accurate third charging parameter, thereby avoiding current backflow caused by the charging adjustment of the power adapter and damaging the components of the power adapter, thereby improving the safety of charging control.

[0097] Furthermore, regardless of the accuracy of the power adapter, the electronic device can obtain the first charging parameter by interacting with the power adapter, thereby ensuring that the charging speed will not be reduced due to the accuracy error of the power adapter, thereby improving the charging speed. At the same time, the process of the power adapter charging the electronic device can avoid the problem of non-rated charging power and slow charging speed caused by the first charging parameter not adjusting the required charging parameter, thereby ensuring a faster charging speed.

[0098] In one embodiment, determining a third charging parameter based on a first charging parameter and a preset second charging parameter includes: determining a step value corresponding to the first charging parameter based on the first charging parameter and the preset second charging parameter; determining the third charging parameter based on the step value corresponding to the first charging parameter and the first charging parameter.

[0099] The step value corresponding to the first charging parameter is a value that changes based on the first charging parameter.

[0100] Optionally, the electronic device determines the difference between the first charging parameter and the preset second charging parameter, and uses the difference as the step value of the first charging parameter. Optionally, the electronic device determines the difference between the first charging parameter and the preset second charging parameter, and determines the step value corresponding to the difference from the corresponding relationship between the preset difference and the step value.

[0101] Optionally, if the first charging parameter is greater than the preset second charging parameter, the first charging parameter is subtracted from the step value to obtain a third charging parameter; if the first charging parameter is less than or equal to the preset second charging parameter, the first charging parameter is added to the step value to obtain the third charging parameter.

[0102] In this embodiment, the electronic device determines the step value corresponding to the first charging parameter based on the first charging parameter and the preset second charging parameter. Then, based on the step value corresponding to the first charging parameter and the first charging parameter, the third charging parameter can be determined more accurately.

[0103] In one embodiment, based on the first charging parameter and the preset second charging parameter, determining the step value corresponding to the first charging parameter includes: determining the absolute value of the difference between the first charging parameter and the preset second charging parameter; based on the size of the absolute value of the difference, determining the step value corresponding to the first charging parameter; there is a positive correlation between the step value and the absolute value of the difference.

[0104] The electronic device pre-sets the step value corresponding to the absolute value of the difference, and there is a positive correlation between the step value and the absolute value of the difference. It can be understood that the larger the absolute value of the difference, the larger the step value; the smaller the absolute value of the difference, the smaller the step value.

[0105] The electronic device divides at least two numerical ranges of the absolute value of the difference, and the step value is positively correlated with any numerical value in the numerical range where the absolute value of the difference is located. It can be understood that there is no intersection between the numerical ranges, and the larger the numerical value in the numerical range where the absolute value of the difference is located, the larger the step value, and the smaller the numerical value in the numerical range where the absolute value of the difference is located, the smaller the step value.

[0106] Taking the first charging parameter as the first voltage parameter and the second charging parameter as the second voltage parameter as an example, the step values ​​step corresponding to each numerical range of the difference absolute value Vdiff are as follows: Vdiff>5v, step=5000mv; 2<=Vdiff<5v, step=2000mv; 1<=Vdiff<2v, step=1000mv; 500mv<=Vdiff<1v, step=500mv; 200<=Vdiff<500mv, step=200mv; Vdiff<200mv, step=100mv.

[0107] If the absolute value of the difference between the first voltage parameter and the preset second voltage parameter is greater than 5V, the step value of the first charging parameter is 5000mv; if the absolute value of the difference between the first voltage parameter and the preset second voltage parameter is greater than or equal to 2V and less than 5V, the step value of the first charging parameter is 2000mv; and so on.

[0108] In this embodiment, the electronic device determines the absolute value of the difference between the first charging parameter and the preset second charging parameter, and the absolute value of the difference is positively correlated with the step value. Therefore, based on the size of the absolute value of the difference, the step value corresponding to the first charging parameter can be determined more accurately.

[0109] In one embodiment, Figure 3 As shown, another charging control method is provided, which is applied to an electronic device, and the charging control method includes the following steps:

[0110] Step S302: When the electronic device is electrically connected to an external power adapter, a first voltage parameter sent by the power adapter is obtained; the first voltage parameter is a voltage parameter actually output by the power adapter.

[0111] Step S304: if the first voltage parameter does not satisfy the preset voltage condition, determine the absolute value of the difference between the first voltage parameter and a preset second voltage parameter.

[0112] Step S306, determining a step value corresponding to the first voltage parameter based on the absolute value of the difference; there is a positive correlation between the step value and the absolute value of the difference.

[0113] Step S308, if the first voltage parameter is less than the second voltage parameter, then add the step value corresponding to the first voltage parameter to the first voltage parameter to obtain the third voltage parameter; if the first voltage parameter is greater than or equal to the second voltage parameter, and the absolute value of the difference is greater than the first preset threshold, then subtract the step value of the first voltage parameter from the first voltage parameter to obtain the third voltage parameter.

[0114] It is understandable that before the electronic device turns on the charge pump (CP) to directly charge the Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET, abbreviated as MOS), that is, before the power adapter charges the battery in the electronic device, the voltage output from the power adapter to the battery needs to be greater than the battery voltage of the electronic device itself, so as to avoid the problem that the battery voltage of the electronic device itself is greater than the voltage output from the power adapter to the battery, causing the current to flow back into the power adapter and damage the components of the power adapter, thereby improving the safety of charging control. Among them, the metal oxide semiconductor field effect transistor is equivalent to the role of a switch. If the metal oxide semiconductor field effect transistor is turned on, the power adapter will directly charge the battery of the electronic device.

[0115] The working principle of the charge pump is to use the charging and discharging of capacitors to achieve voltage conversion. For example, the battery voltage of an electronic device is less than 4.5V, and the first voltage parameter of the power adapter (output voltage vbus) is 8V. Therefore, the voltage needs to be reduced to charge the battery, so a charge pump is needed to reduce the voltage.

[0116] Optionally, the second voltage parameter is greater than a battery voltage parameter of the electronic device, the battery in the electronic device includes at least two battery cells connected in series, and the battery voltage parameter is obtained by adding voltage parameters of each battery cell.

[0117] Optionally, the second voltage parameter is greater than the battery voltage parameter by a specified voltage value. The specified voltage value can be set as needed. In one embodiment, the specified voltage value is 200mv. In other embodiments, the specified voltage value can also be other values, such as 190mv, 201mv, etc., but is not limited thereto.

[0118] Exemplarily, the battery in the electronic device includes two cells connected in series, and the voltage parameter of each cell is 2V, then the battery voltage parameter is 4V, and the second voltage parameter is 200mv greater than the battery voltage parameter, that is, the second voltage parameter is 4.02V.

[0119] It is understandable that if the specified voltage value is too small, such as 100mv, when the path impedance between the power adapter output and the battery of the electronic device is large, it may cause the voltage output from the power adapter to the battery to be less than the battery voltage, resulting in the problem of current backflow to the power adapter. If the specified voltage value is too large, such as 300mv, it may cause the CC loop (current stabilization loop) in the power adapter to be unstable and trigger the OCP (overcurrent protection point), and also damage the components of the power adapter and the battery of the electronic device. Therefore, the second voltage parameter is 200mv greater than the battery voltage parameter of the electronic device, which can avoid damage to the components of the power adapter and the battery of the electronic device, thereby improving safety.

[0120] Optionally, if the first voltage parameter is less than the second voltage parameter, the voltage output by the power adapter to the electronic device may be less than the battery voltage, and the first voltage parameter is too small, so the first voltage parameter is added to the step value corresponding to the first voltage parameter to obtain the third voltage parameter; if the first voltage parameter is greater than or equal to the second voltage parameter, and the absolute value of the difference is greater than the first preset threshold, indicating that the first voltage parameter is too large, the step value corresponding to the first voltage parameter is subtracted from the first voltage parameter to obtain the third voltage parameter.

[0121] The first preset threshold value can be set as required. For example, the first preset threshold value is 300 mv (millivolts), or can be 310 mv, 290 mv, etc.

[0122] Step S310: Send the third voltage parameter to the power adapter to instruct the power adapter to adjust the voltage parameter output by the power adapter based on the third voltage parameter.

[0123] Optionally, the electronic device sends a request communication packet consisting of a third voltage parameter and a third current parameter to the power adapter to instruct the power adapter to adjust the voltage parameter output by the power adapter based on the third voltage parameter, and to adjust the current parameter output by the power adapter based on the third current parameter.

[0124] The third voltage parameter and the third current parameter are used as a pair of data to form a request communication packet, wherein the third current parameter is a lower limit value within the current parameter range.

[0125] In this embodiment, if the first voltage parameter is less than the second voltage parameter, the first voltage parameter is added to the step value corresponding to the first voltage parameter to obtain the third voltage parameter; if the first voltage parameter is greater than or equal to the second voltage parameter and the absolute value of the difference is greater than the first preset threshold, the first voltage parameter is subtracted from the step value corresponding to the first voltage parameter to obtain the third voltage parameter, and the second voltage parameter is greater than the battery voltage parameter of the electronic device, so that the third voltage parameter can be determined more accurately.

[0126] In one embodiment, Figure 4 As shown, another charging control method is provided, which is applied to an electronic device, and the charging control method includes the following steps:

[0127] Step S402: When the electronic device is electrically connected to an external power adapter, a first current parameter sent by the power adapter is obtained.

[0128] Step S404: if the first current parameter does not satisfy the preset current condition, determine the absolute value of the difference between the first current parameter and a preset second current parameter.

[0129] Step S406, determining a step value corresponding to the first current parameter based on the absolute value of the difference; the step value and the absolute value of the difference are positively correlated.

[0130] Step S408, if the first current parameter is greater than or equal to the second current parameter, subtract the step value corresponding to the first current parameter from the first current parameter to obtain the third current parameter; if the first current parameter is less than the second current parameter and the absolute value of the difference is greater than the second preset threshold, add the step value corresponding to the first current parameter to the first charging parameter to obtain the third current parameter.

[0131] It is understandable that during the charging process of the electronic device, as the power increases, the battery voltage parameters will also change, and the battery voltage parameters and the current output by the power adapter to the electronic device battery have a matching relationship, that is, the battery voltage parameters and the first current parameters of the power adapter have a matching relationship. If the first current parameter of the power adapter does not match the battery voltage parameter, that is, the actual current of the power adapter is too large or too small, the battery or the components of the power adapter will be damaged.

[0132] Optionally, if the first current parameter is greater than or equal to the second current parameter, indicating that the output current of the power adapter is too large and will damage the battery of the electronic device, the electronic device will subtract the step value corresponding to the first current parameter from the first current parameter to obtain a third current parameter; if the first current parameter is less than the second current parameter and the absolute value of the difference is greater than the second preset threshold, indicating that the output current of the power adapter is too small and the charging speed is too slow, the first charging parameter will be added to the step value corresponding to the first current parameter to obtain the third current parameter.

[0133] The second preset threshold value can be set as required. For example, the second preset threshold value can be 10 mA (milliamperes).

[0134] Step S410: Send the third current parameter to the power adapter to instruct the power adapter to adjust the current parameter output by the power adapter based on the third current parameter.

[0135] Optionally, before sending the third current parameter to the power adapter, it also includes: determining a voltage parameter corresponding to the third current parameter that meets the preset current pressure difference requirement; sending the voltage parameter that meets the preset current pressure difference requirement to the power adapter to instruct the power adapter to adjust the current first voltage parameter to a voltage parameter that meets the preset current pressure difference requirement.

[0136] It should be noted that before the electronic device adjusts the current parameter of the power adapter to the third current parameter, the actual output voltage of the power adapter needs to meet the current pressure difference requirement. Then, the electronic device determines the voltage parameter that meets the preset current pressure difference requirement corresponding to the third current parameter from the correspondence between the current parameter and the voltage parameter, and sends the voltage parameter that meets the preset current pressure difference requirement to the power adapter to instruct the power adapter to adjust the current first voltage parameter to the voltage parameter that meets the preset current pressure difference requirement. Then, after the power adapter adjusts the first voltage parameter to the voltage parameter that meets the preset current pressure difference requirement, it can receive the third current parameter, thereby accurately adjusting the current and avoiding the problem that the current cannot be adjusted due to the pressure difference not meeting the requirement.

[0137] Optionally, the electronic device sends a third current parameter to the power adapter in response to a voltage adjustment completion signal sent by the power adapter to instruct the power adapter to adjust the current parameter output by the power adapter based on the third charging parameter; the voltage adjustment completion signal is sent after the power adapter adjusts the first voltage parameter to a voltage parameter that meets the preset current voltage difference requirement.

[0138] It can be understood that the electronic device determines the third voltage parameter based on the first voltage parameter and the second voltage parameter to indicate the process (voltage regulation process) of adjusting the power adapter based on the third voltage parameter. Usually, the difference between the first voltage parameter and the third voltage parameter increases, and multiple adjustments are required, and the adjustment precision is relatively large; and before the electronic device adjusts the first current parameter of the power adapter (current regulation process), it is necessary to adjust the first voltage parameter to a voltage parameter that meets the current pressure difference requirements. The first voltage parameter has undergone the voltage regulation process, and the difference between it and the voltage parameter that meets the current pressure difference requirements is small. Usually, it can be adjusted directly at one time, and the adjustment precision is relatively small, that is, the adjustment precision of the first voltage parameter in the voltage regulation process is greater than the adjustment precision of the first voltage parameter in the current regulation process.

[0139] In this embodiment, if the first current parameter is greater than or equal to the second current parameter, the step value corresponding to the first current parameter is subtracted from the first current parameter to obtain a third current parameter, which can avoid damaging the battery of the electronic device and improve safety; if the first current parameter is less than the second current parameter and the absolute value of the difference is greater than the second preset threshold, the first charging parameter is added to the step value corresponding to the first current parameter to obtain the third current parameter, which can increase the charging speed.

[0140] In one embodiment, after obtaining the first charging parameter sent by the power adapter, the electronic device determines whether the first charging parameter presets the charging condition based on the first charging parameter and the preset second charging parameter, including: determining the size relationship and the absolute value of the difference between the first charging parameter and the preset second charging parameter; based on the size relationship and the absolute value of the difference, determining whether the first charging parameter meets the preset charging condition.

[0141] Among them, the preset charging condition can be set as needed, such as the absolute value of the difference between the first charging parameter and the second charging parameter is less than the preset value, the first charging parameter is greater than the second charging parameter, or the first charging parameter is less than the second charging parameter, etc., but is not limited thereto.

[0142] Optionally, the first charging parameter includes a first voltage parameter, the second charging parameter includes a second voltage parameter, and the preset charging condition includes a preset voltage condition; based on the size relationship and the absolute value of the difference, determining whether the first charging parameter meets the preset charging condition, including: if the first voltage parameter is greater than or equal to the second voltage parameter, and the absolute value of the difference is greater than a first preset threshold, or the first voltage parameter is less than the second voltage parameter, then the first voltage parameter does not meet the preset voltage condition; if the first voltage parameter is greater than or equal to the second voltage parameter, and the absolute value of the difference is less than or equal to the first preset threshold, then determining that the first voltage parameter meets the preset voltage condition.

[0143] Optionally, if the first voltage parameter is greater than or equal to the second voltage parameter, and the absolute value of the difference is greater than a first preset threshold value, it indicates that the first voltage parameter is too large and the first voltage parameter does not meet the preset voltage condition; if the first voltage parameter is less than the second voltage parameter, it indicates that the power adapter voltage is insufficient and it is easy to cause current to flow back into the power adapter, and the first voltage parameter does not meet the preset voltage condition; if the first voltage parameter is greater than or equal to the second voltage parameter, and the absolute value of the difference is less than or equal to the first preset threshold value, it not only avoids the first voltage parameter being too large, but also avoids current backflow into the power adapter, and the first voltage parameter meets the preset voltage condition.

[0144] Optionally, the first charging parameter includes a first current parameter, the second charging parameter includes a second current parameter, and the preset charging condition includes a preset current condition; based on the size relationship and the absolute value of the difference, determining whether the first charging parameter meets the preset charging condition, including: if the first current parameter is less than the second current parameter, and the absolute value of the difference is greater than a second preset threshold, or the first current parameter is greater than or equal to the second current parameter, then the first current parameter does not meet the preset current condition; if the first current parameter is less than the second current parameter, and the absolute value of the difference is less than or equal to the second preset threshold, then determining that the first current parameter meets the preset current condition.

[0145] Optionally, if the first current parameter is less than the second current parameter and the absolute value of the difference is greater than a second preset threshold, it means that the first current parameter is too small, resulting in a slow charging speed, and the first current parameter does not meet the preset current condition; if the first current parameter is greater than or equal to the second current parameter, the excessive current will damage the battery of the electronic device, and the first current parameter does not meet the preset current condition; if the first current parameter is less than the second current parameter and the absolute value of the difference is less than or equal to the second preset threshold, it not only avoids the first current parameter being too large to damage the battery, but also avoids the charging speed being too slow, and the first current parameter meets the preset current condition.

[0146] In this embodiment, the electronic device can more accurately determine whether the first charging parameter meets the preset charging condition based on the magnitude relationship and the absolute value of the difference between the first charging parameter and the preset second charging parameter. Further, the electronic device can more accurately determine whether the first voltage parameter and the first current parameter meet the condition based on the specific magnitude relationship and the absolute value of the difference between the first charging parameter and the preset second charging parameter.

[0147] In one embodiment, Figure 5 As shown, another charging control method is also provided, which is applied to an electronic device, and the charging control method includes the following steps:

[0148] Step S502: When the electronic device is electrically connected to an external power adapter, a first voltage parameter sent by the power adapter is obtained.

[0149] Step S504: if the first voltage parameter does not meet the preset voltage condition, a third voltage parameter is determined based on the first voltage parameter and a preset second voltage parameter; the second voltage parameter is greater than the battery voltage parameter of the electronic device.

[0150] Step S506: Send the third voltage parameter to the power adapter to instruct the power adapter to adjust the voltage parameter output by the power adapter based on the third voltage parameter.

[0151] Step S508, executing again the step of obtaining the first voltage parameter sent by the power adapter, until the first voltage parameter meets the preset voltage condition, and adjusting the current parameter output by the power adapter.

[0152] It can be understood that when the electronic device determines that the current first voltage parameter of the power adapter does not meet the preset voltage condition, the third voltage parameter is sent to the power adapter to instruct the power adapter to adjust the first voltage parameter; after the power adapter adjusts the first voltage parameter, it is necessary to obtain the current first voltage parameter of the power adapter again to confirm whether it meets the preset voltage condition, until the current first voltage parameter meets the preset voltage condition, indicating that the voltage adjustment of the power adapter is completed, the electronic device adjusts the current first current parameter of the power adapter.

[0153] Optionally, when the electronic device determines that the first voltage parameter meets the preset voltage condition, it obtains a third current parameter and sends the third current parameter to the power adapter to instruct the power adapter to adjust the current parameter of the power adapter based on the third current parameter.

[0154] Optionally, after the electronic device obtains the first voltage parameter sent by the power adapter, if the first voltage parameter meets the preset voltage condition, the electronic device turns on the charge pump (CP) so that the power adapter charges the battery of the electronic device; during the charging process, the first current parameter sent by the power adapter is adjusted.

[0155] Optionally, after the power adapter completes voltage regulation, use a UFCS adapter with poor accuracy to electrically connect to a UFCS-supported mobile phone, and use an oscilloscope to capture the D+D- waveform (differential input line), vbus waveform, ibus waveform of the power adapter, and the battery voltage waveform corresponding to i2c.

[0156] In this embodiment, if the electronic device determines that the first voltage parameter sent by the power adapter does not meet the preset voltage condition, it will send the third voltage parameter to the power adapter to instruct the power adapter to adjust the current first voltage parameter; and the electronic device needs to continue to determine whether the adjusted current first voltage parameter meets the preset voltage condition, so it needs to execute the step of obtaining the current first voltage parameter of the power adapter again, until the first voltage parameter meets the preset voltage condition, and then adjust the current parameter output by the power adapter, thereby improving the accuracy of the charging parameter adjustment.

[0157] In one embodiment, adjusting the current parameter output by a power adapter includes: obtaining a first current parameter sent by the power adapter; the first current parameter is the current parameter actually output by the power adapter; if the first current parameter does not meet a preset current condition, determining a third current parameter based on the first current parameter and a preset second current parameter; the second current parameter is a current parameter of a target for charging an electronic device through the power adapter; and sending the third current parameter to the power adapter to instruct the power adapter to adjust the current parameter output by the power adapter based on the third current parameter.

[0158] The second current parameter is a target current parameter for charging a battery in the electronic device through a power adapter.

[0159] Optionally, the electronic device obtains the battery voltage and determines a second current parameter that matches the battery voltage according to the curve relationship between the battery voltage and the second current parameter, thereby avoiding the problem of inaccurate third current parameter determined due to the second current parameter being too large or too small. The third current parameter can be determined more accurately, thereby more accurately adjusting the first current parameter of the power adapter.

[0160] Optionally, before the electronic device sends the third current parameter to the power adapter, it also includes: determining a voltage parameter corresponding to the third current parameter that meets the preset current pressure difference requirement; sending the voltage parameter that meets the preset current pressure difference requirement to the power adapter to instruct the power adapter to adjust the current first voltage parameter to a voltage parameter that meets the preset current pressure difference requirement.

[0161] In this embodiment, after the electronic device completes adjusting the first voltage parameter of the power adapter, it obtains the first current parameter sent by the power adapter, which can accurately characterize the current parameter actually output by the power adapter, avoiding data deviation caused by using the current parameter recorded by the software as the first current parameter; if the first current parameter does not meet the preset current condition, the electronic device can more accurately determine the third current parameter for the power adapter based on the first current parameter and the preset second current parameter; the electronic device sends the third current parameter to the power adapter to instruct the power adapter to adjust the current parameter output by the power adapter based on the third current parameter, which can avoid current backflow and damage to the components of the power adapter after the power adapter adjusts the current parameter, thereby improving the safety of charging control.

[0162] In one embodiment, after sending the third current parameter to the power adapter, it also includes: returning to execute the step of obtaining the first current parameter sent by the power adapter, until the first current parameter meets the preset current condition, detecting whether the second current parameter or the second voltage parameter changes; if the second voltage parameter changes, executing the step of obtaining the first voltage parameter sent by the power adapter again; if the second current parameter changes, executing the step of obtaining the first current parameter sent by the power adapter again.

[0163] It is understandable that the battery parameters of the electronic device may change at different charging stages, so the second voltage parameter or the second current parameter output by the power adapter to the battery of the electronic device may also change.

[0164] Optionally, after the electronic device completes adjusting the first voltage parameter and the first current parameter of the power adapter, it detects in real time whether the second current parameter or the second voltage parameter changes.

[0165] Optionally, if the second voltage parameter changes, the current first voltage parameter of the power adapter may not meet the preset voltage condition, then the step of obtaining the first voltage parameter sent by the power adapter is performed again to re-determine whether the current first voltage parameter of the power adapter meets the preset voltage condition, and adjust the voltage parameter output by the power adapter if the preset voltage condition is not met.

[0166] Similarly, if the second current parameter changes, the current first current parameter of the power adapter may not meet the preset current condition, then the step of obtaining the first current parameter sent by the power adapter is performed again to re-determine whether the current first current parameter of the power adapter meets the preset current condition, and adjust the current parameter output by the power adapter if the preset current condition is not met.

[0167] In this embodiment, after the electronic device completes adjusting the first voltage parameter and the first current parameter of the power adapter, it detects whether the second current parameter or the second voltage parameter has changed, and if the second current parameter or the second voltage parameter has changed, it readjusts the first voltage parameter and the first current parameter of the power adapter. Even in different charging stages, the first voltage parameter and the first current parameter of the power adapter can be accurately adjusted to enable more accurate and safer charging.

[0168] In one embodiment, the above method also includes: when the electronic device controls the power adapter to adjust the first voltage parameter, sending the current lower limit value for the power adapter to the power adapter to instruct the power adapter to adjust the current first current parameter to the lower limit value.

[0169] Optionally, when the electronic device controls the power adapter to adjust the first voltage parameter, the electronic device obtains a lower limit value within the current parameter range for the power adapter and sends the lower limit value to the power adapter. The lower limit value within the current parameter range of the power adapter is the minimum output current of the power adapter within the output current parameter range.

[0170] Optionally, when the electronic device controls the power adapter to adjust the first voltage parameter, and the power adapter does not charge the electronic device with a large current, the power adapter outputs a lower current limit value, which can save charging resources of the power adapter.

[0171] In one embodiment, before obtaining the first charging parameter sent by the power adapter, it also includes: obtaining at least one charging mode supported by the power adapter; determining a target charging mode from at least one charging mode; the target charging mode includes a charging parameter range corresponding to the target charging mode supported and output by the power adapter; sending a third charging parameter to the power adapter includes: determining whether the third charging parameter is within the charging parameter range, and if so, sending the third charging parameter to the power adapter.

[0172] Optionally, when the electronic device and an external power adapter are electrically connected, if it is determined that the electronic device and the power adapter are charged using the fused fast charging protocol, the electronic device sends a charging mode request command (get outputcapability) to the power adapter to instruct the power adapter to send at least one supported charging mode to the electronic device.

[0173] Wherein, at least one charging mode includes a charging parameter range, and the charging parameter range may include a voltage parameter range and / or a current parameter range, and the charging parameter output by the power adapter is within the charging parameter range. Exemplarily, the voltage parameter output by the power adapter is within the voltage parameter range, and the current parameter output by the power adapter is within the current parameter range.

[0174] The power adapter may support at least one charging mode, such as 1 charging mode, 2 charging modes or 15 charging modes, and the upper limit value of the charging parameter range of each charging mode gradually increases.

[0175] Optionally, the electronic device is not limited to the method of determining the target charging mode from at least one charging mode. It can be randomly selecting a charging mode from at least one charging mode as the target charging mode, or the charging mode with the largest upper limit value of the charging parameter range can be used as the target charging mode, without limitation thereto.

[0176] Optionally, the electronic device matches the third charging parameter with the charging parameter range of the target charging mode. If the third charging parameter is within the charging parameter range of the target charging mode, the third charging parameter is sent to the power adapter; if the third charging parameter is not within the charging parameter range, the target charging mode is changed, wherein the third charging parameter matches the charging parameter range of the target charging mode after switching.

[0177] Optionally, after the electronic device changes the target charging mode, it sends an instruction corresponding to the new target charging mode to the power adapter to instruct the power adapter to switch to the new target charging mode and support the third charging parameter under the new target charging mode.

[0178] Exemplarily, the third voltage parameter ask_volt of the electronic device is less than or equal to the upper limit value max_volt of the voltage parameter range, and greater than or equal to the lower limit value min_volt of the voltage parameter range: min_volt<=ask_volt<=max_volt; the third current parameter ask_curr of the electronic device is less than or equal to the upper limit value max_curr of the current parameter range, and greater than or equal to the lower limit value min_curr of the current parameter range: min_curr<=ask_curr<=max_curr.

[0179] In this embodiment, after the electronic device determines the target charging mode supported by the power adapter, if the third charging parameter is within the charging parameter range supported by the target charging mode, the power adapter can be accurately instructed to make adjustments based on the third charging parameter within the charging parameter range supported; if the third charging parameter is not within the charging parameter range supported by the target charging mode, the target mode is changed so that the third charging parameter is within the charging parameter range supported by the new target charging mode, thereby avoiding the power adapter being unable to support the third charging parameter and being unable to make adjustments, and the charging parameters can be adjusted more accurately.

[0180] In one embodiment, Figure 6 As shown, a charging control method is provided, which is applied to Figure 1 The following steps are used as an example to illustrate the power adapter in the figure:

[0181] Step S602, when the external electronic device and the power adapter are electrically connected, obtain a first charging parameter, and send the first charging parameter to the electronic device, so that when the first charging parameter does not meet the preset charging condition, the electronic device determines a third charging parameter based on the first charging parameter and the preset second charging parameter; wherein the first charging parameter is the charging parameter actually output by the power adapter, and the second charging parameter is the target charging parameter for charging the electronic device through the power adapter.

[0182] Optionally, when an external electronic device and a power adapter are electrically connected, the power adapter responds to a pulse string sent by the electronic device, sends a response signal of the pulse string to the electronic device, and switches to UFCS mode; the electronic device is configured to send a ping control command to the power adapter after receiving the response signal of the pulse string; the power adapter responds to the ping control command sent to the electronic device, and sends a response signal of the ping control command to the electronic device in UFCS mode; the electronic device is configured to determine that the electronic device and the power adapter are charging using the fused fast charging protocol after receiving the response signal of the pulse string.

[0183] Optionally, the electronic device sends a charging parameter request command to the power adapter when integrating the fast charging protocol; the power adapter sends a confirmation control command to the electronic device in response to the charging parameter request command sent by the electronic device, obtains the current first charging parameter, and sends the first charging parameter to the electronic device; the electronic device is used to start the timer after receiving the confirmation control command, and receive the first charging parameter sent by the power adapter within the preset timing duration of the timer.

[0184] Optionally, the power adapter includes a charging circuit; the power adapter samples charging parameters of the charging circuit, and determines the current first charging parameter of the power adapter based on each sampled data, wherein the sampled data may be an output voltage or an output current.

[0185] Optionally, the power adapter samples the output voltage of the charging circuit, averages the sampled data of each output voltage, and obtains the current first voltage parameter of the power adapter; the power adapter samples the output current of the charging circuit, averages the sampled data of each output current, and obtains the current first current parameter of the power adapter. In other optional embodiments, the weighted average method, screening method, and random selection method can also be used to process each sampled data to obtain the first charging parameter, which is not limited here.

[0186] Step S604: receiving a third charging parameter sent by the electronic device, and adjusting the output charging parameter based on the third charging parameter.

[0187] Optionally, the power adapter adjusts the output charging parameter based on the third charging parameter within a preset time period; when the preset time period is reached, the charging parameter request command sent by the electronic device is received again, and the adjusted current first charging parameter is sent to the electronic device.

[0188] In the above charging control method, when the external electronic device and the power adapter are electrically connected, the power adapter obtains the first charging parameter and sends the first charging parameter to the electronic device, so that when the first charging parameter does not meet the preset charging condition, the electronic device determines the third charging parameter based on the first charging parameter and the preset second charging parameter; wherein the first charging parameter is the charging parameter actually output by the power adapter, which can avoid the data deviation caused by taking the charging parameter recorded by the software as the actual charging parameter, and the second charging parameter is the charging parameter of the target of charging the electronic device through the power adapter, which can determine a more accurate third charging parameter; then, the power adapter receives the third charging parameter sent by the electronic device, and can adjust the output charging parameter based on the more accurate third charging parameter, avoiding the power adapter to adjust the charging and causing the current to flow back and damage the device of the power adapter, thereby improving the safety of charging control. In one embodiment, the first charging parameter includes the first current parameter, the second charging parameter includes the second current parameter, and the third charging parameter includes the third current parameter; before receiving the third charging parameter sent by the electronic device, it also includes: receiving the voltage parameter corresponding to the third current parameter sent by the electronic device and meeting the preset current pressure difference requirement; adjusting the current first voltage parameter to the voltage parameter meeting the preset current pressure difference requirement.

[0189] It is understandable that before the power adapter adjusts the first current parameter, it is necessary to adjust the first voltage parameter to a voltage parameter that meets the preset current voltage difference requirement, so as to accurately adjust the current and avoid the problem of being unable to adjust the current due to the voltage difference not meeting the requirement.

[0190] In one embodiment, the first charging parameter includes a first voltage parameter, the second charging parameter includes a second voltage parameter, the second voltage parameter is greater than the battery voltage parameter of the electronic device, and the third charging parameter includes a third voltage parameter; the above method also includes: when the power adapter adjusts the first voltage parameter, obtaining the current lower limit value for the power adapter sent by the electronic device, and adjusting the current first current parameter to the lower limit value.

[0191] It is understandable that when the power adapter adjusts the first voltage parameter, if the power adapter does not charge the electronic device with a large current, the current first current parameter is adjusted to the lower limit value, that is, the minimum current value of the current parameter range, which can save the charging resources of the power adapter. If the current is too large during the voltage adjustment period, and the voltage difference between the power adapter and the battery of the electronic device is not enough, the battery current may be backflowed into the power adapter, damaging the components of the power adapter.

[0192] Exemplarily, the lower limit value within the current parameter range is 1A (ampere).

[0193] In one embodiment, before sending the first charging parameter to the electronic device, it also includes: sending at least one charging mode supported by the power adapter to the electronic device to instruct the electronic device to determine a target charging mode from at least one charging mode; the target charging mode includes a charging parameter range corresponding to the target charging mode supported by the power adapter, and when the third charging parameter is within the charging parameter range, performing the step of receiving the third charging parameter sent by the electronic device.

[0194] It can be understood that if the third charging parameter is within the charging parameter range of the target charging mode, the power adapter receives the third charging parameter sent by the electronic device; if the third charging parameter is not within the charging parameter range, and the third charging parameter is within the charging parameter range of the new target charging mode, the power adapter responds to the instruction corresponding to the new target charging mode sent by the electronic device, switches to the new target charging mode, and receives the third charging parameter sent by the electronic device in the new target charging mode, and adjusts the charging parameter based on the third charging parameter within the charging parameter range of the new target charging mode.

[0195] In this embodiment, the power adapter sends at least one charging mode supported by the power adapter to the electronic device to instruct the electronic device to determine a target charging mode from at least one charging mode, so that adjustment can be made based on a third charging parameter within the charging parameter range supported by the target charging mode, thereby avoiding the problem that the third charging parameter cannot be adjusted because it is not within the charging parameter range of the target charging mode, thereby improving the accuracy of charging control.

[0196] In one embodiment, Figure 7 As shown, the electronic device is inserted into the power adapter, and the electronic device and the power adapter are electrically connected; the electronic device determines whether the power adapter has a UFCS handshake response and a ping response. If the power adapter does not have a UFCS handshake response or a ping response, the electronic device and the power adapter are charged using a non-UFCS fast charging protocol; if the power adapter has a UFCS handshake response and a ping response, the electronic device sends a charging mode request command to the power adapter, obtains at least one charging mode supported by the power adapter, and enters the voltage regulation logic.

[0197] In the voltage regulation logic, the electronic device obtains the second voltage parameter and the second current parameter, sends a charging parameter request command to the power adapter, and detects whether the power adapter replies to the confirmation control command; if it is detected that the power adapter does not reply to the confirmation control command, it is determined whether the number of retransmissions exceeds the preset number; if the number of retransmissions does not exceed the preset number, the charging parameter request command is resent to the power adapter; if the number of retransmissions exceeds the preset number, the processing is stopped; if it is detected that the power adapter replies to the confirmation control command, it is determined whether a data packet is received within the preset time length; if the data packet is not received within the preset time length, it is determined whether the number of retransmissions exceeds the preset number; if the number of retransmissions does not exceed the preset number, the charging parameter request command is resent to the power adapter; if the number of retransmissions exceeds the preset number, the processing is stopped; if the data packet is received within the preset time length, the data packet is parsed to obtain the first voltage parameter and the first current parameter. Among them, the first voltage parameter and the first current parameter are a pair of data, and the first current parameter is the lower limit value, 1 ampere.

[0198] The electronic device obtains the absolute value of the difference between the first voltage parameter and the second voltage parameter, and determines the step value corresponding to the absolute value of the difference; determines whether the first voltage parameter is less than the second voltage parameter, and if so, the first voltage parameter plus the step value is obtained to obtain the third voltage parameter, and the third voltage parameter and the third current parameter are assembled into a request communication packet, and sent to the power adapter to instruct the power adapter to adjust the output voltage parameter based on the third voltage parameter, and re-enter the voltage regulation logic; if the first voltage parameter is greater than or equal to the second voltage parameter, it is determined whether the first voltage parameter is greater than the second voltage parameter by more than 300 millivolts, and if so, the first voltage parameter is subtracted from the step value to obtain the third voltage parameter, and the third voltage parameter and the third current parameter are assembled into a request communication packet, and sent to the power adapter to instruct the power adapter to adjust the output voltage parameter of the power adapter based on the third voltage parameter, and re-enter the voltage regulation logic; if the first voltage parameter is greater than or equal to the second voltage parameter, and the first voltage parameter is within 300 millivolts greater than the second voltage parameter, the voltage regulation is completed, and the current regulation logic is entered. In the current regulation logic, the initial value of the first current parameter is the lower limit value within the current parameter range, such as 1 ampere.

[0199] After the power adapter completes current regulation, the electronic device checks whether the second voltage parameter and the second current parameter have changed; if the second voltage parameter has changed, it enters node 1, that is, enters the voltage regulation logic; if the second voltage parameter has not changed, it determines whether the second current parameter has changed, and if the second current parameter has changed, it re-enters the current regulation logic; if the second current parameter has not changed, it continues to check whether the second voltage parameter and the second current parameter have changed.
