[0049] The technical solution of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0050] like Figure 1 As shown, this embodiment provides a charging method, including:

[0051] Step 101: If the charging device is currently in the first charging mode, send a trigger signal to the charging device so that the charging device performs a circuit reset based on the trigger signal;

[0052] Step 102: Based on the execution of the circuit reset, the charging device switches from the first charging mode to the second charging mode, wherein the charging power in the second charging mode is greater than that in the first charging mode;

[0053] Step 103: Receive electrical energy provided by the charging device in the second charging mode.

[0054] In this application, the charging method can be applied to various electronic devices that support fast charging protocols, such as mobile phones, tablets, headphones, personal media players, etc. When the electronic device is connected to a charging device that supports the same fast charging protocol for charging, the electronic device can determine whether the current charging mode of the charging device is fast charging mode by monitoring the voltage signal changes on the D+ and D- signal lines. If it is determined that the current charging mode of the charging device is not fast charging mode, the charging state of the current charging device is determined to be abnormal, triggering the charging device to execute a restart process.

[0055] In an implementation, if the electronic device supports a Quick Charge (QC) 3.0+ charging protocol provided by Qualcomm, when the electronic device is connected with a charging device also supporting the QC 3.0+ charging protocol, the electronic device can send a first voltage timing signal to the charging device, and receive a first voltage parameter returned by the charging device based on the first voltage timing signal, if the first voltage parameter is outside a first preset voltage parameter range, it is determined that the charging device is currently in a first charging mode (such as a charging mode of the QC 3.0 charging protocol), at this time, the electronic device can send a trigger signal to the charging device, so that the charging device performs a circuit reset based on the trigger signal, and based on the charging device performing the circuit reset, if the first voltage parameter is within the first preset voltage parameter range, it is determined that the charging device is currently in a second charging mode (a charging mode of the QC 3.0+ charging protocol). Thus, the purpose of switching the charging device from the first charging mode to the second charging mode is achieved.

[0056] Here, the first voltage timing signal can refer to a voltage timing signal when the electronic device identifies whether the charging device is a QC 3.0+ charging protocol. For example, if the output voltage of the charging device is 5V under the QC 3.0 charging protocol, if the first voltage parameter represents that the current output voltage of the electronic device is 6V, it is determined that the charging device is currently in the QC 3.0+ mode, and if the current output voltage of the electronic device is less than or equal to 5V, it is determined that the electronic device is currently in a charging mode other than QC 3.0+ (such as QC 3.0 mode, QC 2.0 mode or BC1.2 mode).

[0057] In this application, the charging power in the second charging mode is greater than that in the first charging mode. For example, the first charging mode is the QC 3.0 protocol mode, and the second charging mode is the QC 3.0+ protocol mode. Wherein, QC3.0 QC3.0 provides flexible selection of different voltages in the voltage range of 3.6V to 20V with an increment of 200mV. The QC 3.0+ protocol is upgraded based on QC 3.0, so there is no need to improve the cost of the device.

[0058] Here, the output power of the QC 3.0 charging protocol can be 15W, 18W and 20W, and the output power of the QC 3.0+ charging protocol is usually greater than or equal to 30W.

[0059] In addition, since the QC3.0+ charging protocol is forward compatible with all QC charging protocols, for example, the QC3.0+ charging protocol is forward compatible with the QC3.0 charging protocol, the QC2.0 charging protocol, and the BC1.2 charging protocol. In order for the charging device to be compatible with all electronic devices supporting these charging protocols, the charging device can sequentially detect whether the voltage parameters corresponding to these charging protocols meet the conditions during the circuit reset process. If the conditions are met, the detection of the next charging protocol is performed. If the conditions are not met, the current charging protocol is used to provide power to the electronic device.

[0060] Based on this, the electronic device can also send a second voltage timing signal (such as a QC3.0 charging protocol signal) to the charging device before sending the first voltage timing signal to the charging device, to detect whether the current charging device supports the QC3.0 charging protocol. If the second voltage parameter returned by the charging device based on the second voltage timing signal is received, it is determined whether the second voltage parameter is within a second preset voltage parameter range. If the determination result indicates that the second voltage parameter is within the second preset voltage parameter range, it means that the charging device supports the QC3.0 charging protocol, and then the first voltage timing signal (such as a QC3.0+ charging protocol signal) is sent to the charging device.

[0061] In this application, the electronic device can also send a third voltage timing signal (such as a QC2.0 charging protocol signal) to the charging device before sending the second voltage timing signal to the charging device, to detect whether the charging device supports the QC2.0 charging protocol, and receive the third voltage parameter returned by the charging device based on the third voltage timing signal. Then it is determined whether the third voltage parameter is within a third preset voltage parameter range. If the determination result indicates that the third voltage parameter is within the third preset voltage parameter range, it means that the charging device supports the QC2.0 charging protocol, and then the second voltage timing signal is sent to the charging device.

[0062] Here, the QC2.0 charging protocol usually supports three fixed voltages of 5V, 9V, and 12V. After determining that the mobile phone side and the charger side both support the QC2.0 charging protocol, the input voltage is directly jumped from 5V to 9V or 12V and continuously increased to the total power, resulting in very high power consumption of the mobile phone. QC3.0 supports a fluctuating voltage of 3.6V to 12V, allowing the input voltage to start from 3.6V, with a step of 0.2V, and adjusting in real time based on factors such as battery temperature, conversion efficiency, and power. Within the allowed input voltage range (9V or 12V), it is gradually increased or decreased. Thus, the power consumption of the mobile phone is reduced.

[0063] In the present application, the electronic device can further send a fourth voltage timing signal (such as a battery charging (BC, Battery Charging) 1.2 signal) to the charging device before sending the third voltage timing signal to the charging device, so as to detect whether the charging device supports the BC1.2 charging protocol; if the electronic device receives a fourth voltage parameter returned by the charging device based on the fourth voltage timing signal, it is judged whether the fourth voltage parameter is within a fourth preset voltage parameter range; if the judgment result represents that the fourth voltage parameter is within the fourth preset voltage parameter range, it is determined that the charging device supports the BC1.2 charging protocol; then the electronic device sends the third voltage timing signal to the charging device again.

[0064] Here, the BC1.2 charging protocol is used to standardize the requirements of battery charging, and the output power is usually 7.5W. The BC1.2 charging protocol mainly includes the following USB port types: standard downlink port (SDP, Standard Downlink Port), dedicated charging port (DCP, Dedicated Charging Port) and downlink charging port (CDP, Downlink Charging Port). Among them, SDP only supports data protocol and does not support charging protocol (such as ordinary USB data transmission interface); DCP only supports charging protocol and does not support data protocol (such as wall charger and car charger), and CDP supports both data protocol and charging protocol (such as computer interface). QC2.0, QC3.0 and QC3.0+ will continue to be detected only when the charging device is a DCP type charging port.

[0065] In the present application, if the second voltage parameter is outside the second preset voltage parameter range, the electronic device determines that the charging device is currently in a third charging mode (such as QC2.0 mode), and receives the power provided by the charging device in the third charging mode. If the second voltage parameter is within the second preset voltage parameter range, but if the third voltage parameter is outside the third preset voltage parameter range, the electronic device determines that the charging device is currently in a fourth charging mode (such as DCP mode); and receives the power provided by the charging device in the fourth charging mode. If the third voltage parameter is within the third preset voltage parameter range, but if the fourth voltage parameter is outside the fourth preset voltage parameter range, the electronic device determines that the charging device is currently in a fifth charging mode (such as CDP mode or SDP mode), and receives the power provided by the charging device in the fifth charging mode.

[0066] Next, the identification process of each charging mode is introduced:

[0067] Figure 2The identification process of the BC1.2 charging protocol is shown in FIG. 1. Figure 2

[0068] First, the mobile phone applies a 0.6V voltage to the D+ signal line. If the mobile phone detects a 0V voltage on the D- signal line, it is determined that the D- signal line and the D+ signal line are not connected, so the voltage on the D+ signal line cannot be transmitted to the D- signal line. In this case, it is determined that the USB 2.0 interface currently connected to the mobile phone is an SDP type port, for example, a USB interface that can only transmit data. If the mobile phone detects a 0.6V voltage on the D- signal line, it is determined that the mobile phone is connected to a CDP (a high-power charging + communication port, for example, a computer) or a DCP (a dedicated charging port, for example, a wall charger), because the D+ signal line and the D- signal line are connected. The mobile phone continues to apply a 0.6V voltage to the D- signal line. If the mobile phone detects a 0.6V voltage on the D+ signal line, it is determined that the USB interface currently connected to the mobile phone is a DCP type port, that is, the USB interface connected to the mobile phone is a dedicated charger. Then, the D+ signal line is pulled up to 3V or 0.6V. If the mobile phone detects a 0V voltage on the D+ signal line, it is determined that the USB interface currently connected to the mobile phone is a CDP type port with a large current and charging capability, for example, a computer. Then, the voltage on the D- and D+ signal lines of the mobile phone is released.

[0069] Figure 3 The identification process of the QC2.0 charging protocol is shown in FIG. 2. Figure 3

[0070] Here, since the QC2.0 charging protocol is based on the BC1.2 charging protocol and is compatible with the BC1.2 charging protocol, the mobile phone pulls up the D+ signal line to 3V or 6V when it is determined that the USB interface currently connected is a DCP type port. Then, the DCP port is controlled to disconnect the D- signal line and the D+ signal line after 1.25S. Then, it is determined whether the voltage on the D- signal line decreases. If it is detected that the voltage on the D- signal line decreases, it is determined that the USB interface currently connected is a QC type charger.

[0071] In this application, since the QC3.0 charging protocol is compatible with the QC2.0 charging protocol, the mobile phone controls the D+ signal line and the D- signal line to allow the charging head of the QC charger to first increase and then decrease the voltage to the default output voltage (for example, 5V) at a step of 200mv based on the QC2.0 charging protocol. In this process, if the charging head can complete the increase and decrease of the voltage at a step of 200mv, it is determined that the current charger is a QC3.0 type, otherwise it is a QC2.0 type.

[0072] ​​For example, it can be: first boost 3.2V, last 0.1 seconds, and then reduce 3.2v, if the default voltage 5v can be output at this time, it is QC3.0 type charger.

[0073] In this application, since QC3.0+ charging protocol is based on the improvement of QC3.0 charging protocol, on the basis of QC3.0 charging protocol process, if the charger is QC3.0+ type, the charger will output higher voltage to the mobile phone end, otherwise it is not QC3.0+ type charger, but QC3.0 type charger.

[0074] For example, on the basis of QC3.0 charging protocol process, the mobile phone end continues to detect the output voltage of the charger, and if it is detected that the charger outputs 6V voltage (such as QC3.0 charging protocol output default voltage 5v), it is QC3.0+ type charger.

[0075] In this application, the electronic device can also mark the current charging mode of the charging device under the condition that the charging device is currently in the first charging mode, and after the charging device executes circuit reset, if the mark meets the parameter condition, the electronic device receives the power provided by the charging device in the first charging mode.

[0076] Here, the mark meets the parameter condition, at least including one of the following methods:

[0077] If the number of times of marking the first mode of the charging device is greater than or equal to the number of times threshold, it is determined that the mark meets the condition;

[0078] If the marking time of the charging device for the first mode is greater than or equal to the time threshold, it is determined that the mark meets the condition.

[0079] For example, after the charging device executes circuit reset, the electronic device obtains the marking number of times of the charging device "2", and compares the marking number of times with the number of times threshold "2", according to the comparison result, it is determined that the marking number of times "2" is equal to the number of times threshold "2", it is determined that the mark meets the condition, and the power provided by the charging device in the first charging mode is received.

[0080] For another example, after the charging device executes circuit reset, the electronic device obtains the marking time of the charging device "30 seconds", and compares the marking time with the time threshold "20 seconds", according to the comparison result, it is determined that the marking time "30 seconds" is greater than the time threshold "20 seconds", it is determined that the mark meets the condition, and the power provided by the charging device in the first charging mode is received.

[0081] In the present application, if the electronic device determines that the charging device is currently in the second charging mode (such as the QC3.0+ charging mode), the marking of the current charging mode of the charging device can also be cleared.

[0082] The charging method provided in the present application can automatically determine whether the charging device is in the fast charging mode through the output voltage of the current charging device. When it is determined that the charging device is in the non-fast charging mode, it indicates that the charging of the charging device is abnormal, and the charging device can be reset to switch to the fast charging mode to continue charging the target terminal in the case of charging device charging abnormality.

[0083] Figure 4 The flowchart of the charging method in the present application Figure Two As shown in Figure 4 comprises:

[0084] Step 401, detecting the charging device executing the BC1.2 charging protocol;

[0085] Here, the electronic device detects the BC1.2 after detecting that the charger plug is inserted into the electronic device.

[0086] Step 402, determining whether the current charging device is a DCP type charging port; if it is a DCP type charging port, executing step 403; if it is not a DCP type charging port, executing step 409;

[0087] Here, if it is detected that the current charger is of the DCP type, QC2.0 type detection is continued.

[0088] Step 403, determining whether the current charging device is working in the QC2.0 mode; if it is working in the QC2.0 mode, executing step 404; if it is not working in the QC2.0 mode, executing step 409;

[0089] Here, if it is detected that the current charger is of the QC2.0 type, QC3.0 type detection is continued;

[0090] Step 404, determining whether the current charging device is working in the QC3.0 mode; if it is working in the QC3.0 mode, executing step 405; if it is not working in the QC3.0 mode, executing step 409;

[0091] Here, if the current charger is of the QC3.0 type, QC3.0+ type detection is performed;

[0092] Step 405, detecting the charging device executing the QC3.0+ charging protocol;

[0093] Step 406, judging whether the current charging device is working in the QC3.0+ mode; if yes, executing step 407; if not, executing step 410;

[0094] Here, if it is detected that the current charger is of the QC3.0+ type, the QC3.0+ fast charging mode is entered, and the charging flag is cleared; if it is detected that the current charger is not of the QC3.0+ type, the circuit of the charger is reset.

[0095] Step 407, clearing the charging flag;

[0096] Step 408, entering the QC3.0+ fast charging mode to provide power to the electronic device in the QC3.0+ fast charging mode.

[0097] Step 409, entering the ordinary charging mode to provide power to the electronic device in the ordinary charging mode.

[0098] Here, the ordinary charging mode represents a non-fast charging mode. For example, the ordinary charging mode can be a QC2.0 mode, a DCP type BC1.2 mode, a CDP type BC1.2 mode, or an SDP type BC1.2 mode. The current ordinary charging mode is determined according to the currently detected charging protocol type. If the current detection of the charging device is the QC2.0 charging protocol, and the detection result indicates that the current charging device does not support the QC2.0 charging protocol, the power is output in the upper level charging mode of the QC2.0 charging protocol, for example, the upper level charging mode of the QC2.0 charging protocol is the detection of the DCP type, and the power is output in the DCP type. If the current detection of the charging device is the DCP type, and the detection result indicates that the current charging device does not support the DCP type, the power is output in the CDP type or the SDP type.

[0099] Here, in the non-fast charging mode, the charging process of a mobile phone, for example, is as follows: the 220V mains voltage is first reduced to 5V through the charging head, the internal circuit of the mobile phone reduces the 5V voltage to 4.2V, and then the power is delivered to the battery. In the entire voltage reduction process, heat energy is generated. In the fast charging mode, the power management chip is placed in the mobile phone, the power management chip manages and monitors the entire charging process of the lithium battery, including a complex processing algorithm, the lithium battery charging includes several stages, the pre-charging stage, the constant current charging stage, the constant voltage charging stage, and the trickle charging stage. The charging management chip sends instructions to the charger according to the electrical characteristics of each stage of the lithium battery charging process, to inform the charger to change the charging voltage and current, and the charger receives the demand from the charging management system to adjust the output parameters of the charger in real time, to realize fast charging in cooperation with the charging management system.

[0100] Step 410, determine whether there is a charging mark at present; if there is a charging mark, execute step 411, if there is no charging mark, execute step 412;

[0101] Step 411, enter QC3.0 charging mode to provide power to the electronic device in QC3.0 charging mode.

[0102] Step 412, set the charging mark, and execute step 401.

[0103] Here, the reporting of the charger type change information is shielded during the execution of the circuit reset of the charging device, until the process of executing the circuit reset is completed, and the charging mark is cleared.

[0104] The electronic device of the present application triggers the charging device to forcibly execute circuit reset when the charging device is in non-QC3.0+ fast charging mode, and detects the BC1.2, QC2.0, QC3.0, and QC3.0+ processes. If the detection result is QC3.0+ charging, the charging device enters QC3.0+ charging mode at this time. In this way, when a charging head supporting the QC3.0+ charging protocol charges an electronic device supporting the QC3.0+ charging protocol, the charging device can forcibly execute circuit reset when it is working in non-QC3.0+ charging mode, so as to restore the charging device from an abnormal working state to a normal working state.
