Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The quick charging method of the mobile device provided by the embodiment of the invention is executed by the electronic device, and correspondingly, the quick charging device of the mobile device is operated in the electronic device.
Fast charging places certain demands on both the mobile device and the electronic device, both in software and in hardware.
At the software level, the mobile device and the electronic device (which may be, for example, devices that charge the mobile device, such as a charger and a mobile power supply) need to support the same charging protocol. The electronic device performs handshake communication with the mobile device according to the charging protocol, thereby identifying whether the mobile device supports the same charging protocol. And when the charging protocols supported by the mobile equipment are the same, carrying out charging power negotiation between the electronic equipment and the mobile equipment so as to realize quick charging of the mobile equipment. Among other common charging protocols include: power Delivery management (PD) protocol, quick Charge (QC) protocol, super Charge protocol (Super Charge Protocol, SCP), quick Charge protocol (Fast Charge Protocol, FCP), VOOC protocol, adaptive Quick Charge (Adaptive Fast Charging, AFC) protocol, and the like.
In terms of hardware requirements, in addition to the mobile device and the electronic device being required to carry a charging chip capable of supporting a charging protocol and the battery supporting high-power charging, a cable connecting the mobile device and the electronic device is required to meet the charging power transmission requirement of the charging protocol. The USB Type-C interface (hereinafter referred to as USB-C interface) is also a charging connection interface adopted by most of the mobile devices on the market. The USB3.1 standard requires that the production of a USB-C interface and a USB-C To USB-C data line (hereinafter referred To as a C-C data line) be unified, and the USB-C interface and the C-C data line produced under the USB3.1 standard can meet the charging power transmission requirements of all charging protocols on the cable and the interface. Therefore, the method and the electronic device are designed based on the USB-C interface. And the USB-C interface has good compatibility to the charging protocol, and the electronic equipment can be provided with only one USB-C interface for charging output and handshake communication.
The quick charging method of the mobile device provided in the embodiment of the present application is described below from the perspective of an electronic device, which may be a charger or a mobile power supply, and is not specifically limited.
Referring to fig. 1, a flowchart of a fast charging method for a mobile device according to an embodiment of the present application is shown. The quick charging method of the mobile device provided by the embodiment of the application comprises the following steps.
S10: and carrying out first handshake communication with the mobile equipment according to a first charging protocol to judge whether the mobile equipment supports the first charging protocol.
The first charging protocol is a universal charging protocol with the widest application range, and is currently a PD protocol with the widest application range.
The electronic equipment performs first handshake communication with the mobile equipment by using a charging protocol with the widest application range, and can identify that the mobile equipment can support quick charging when the mobile equipment is accessed as far as possible so as to perform quick charging on the mobile equipment, so that the risk of mismatching of the mobile equipment and the electronic equipment due to the charging protocol is reduced.
In an alternative embodiment, the communicating with the mobile device according to the first charging protocol to determine whether the mobile device supports the first charging protocol includes:
Sending a first handshake request to the mobile device according to the first charging protocol to acquire a first response signal fed back by the mobile device;
comparing the first response signal with a response signal standard in the first charging protocol to judge whether the mobile equipment supports the first charging protocol or not;
determining that the mobile device supports the first charging protocol when the first response signal meets a response signal criterion in the first charging protocol;
when the first response signal does not meet response signal criteria in the first charging protocol, it is determined that the mobile device does not support the first charging protocol.
The first handshake request is a data packet including parameters related to a first charging protocol. The first response signal is a data packet comprising the device identification and the supported protocol details.
The process of verifying whether the mobile device supports the first charging protocol is as follows:
when the mobile device receives a first handshake request sent by the electronic device through the USB-C interface, the mobile device checks relevant parameters in the first handshake request to determine the type of the charging protocol. After determining that the charging protocol is the first charging protocol, the mobile device performs a self-test to verify whether hardware and software required by the first charging protocol are available. If the software and hardware of the mobile device support the first charging protocol, the mobile device generates first response information and sends the first response information to the electronic device to inform the electronic device of which charging protocols, supported power levels, voltages, currents and the like can be used by the electronic device.
And after the electronic equipment receives the first response information, verifying the support protocol details in the first response information according to the first charging protocol. When the power supply level, voltage and current of the first charging protocol can meet the power level, voltage and current supported by the mobile equipment in the first response information, determining that the mobile equipment supports the first charging protocol; and when the power supply level, voltage and current of the first charging protocol cannot meet the power level, voltage and current supported by the mobile equipment in the first response information, determining that the mobile equipment does not support the first charging protocol.
In an alternative embodiment, to respond to the charging requirement of the mobile device in time, before performing the first handshake communication, the electronic device further performs operations comprising:
detecting the voltage of a charging interface to judge whether the mobile equipment is connected to the charging interface or not;
and when the voltage of the charging interface changes, determining that the mobile equipment is connected to the charging interface.
It should be appreciated that there are two configuration channels for the USB-C interface to communicate and detect the connection status of the device. The voltage on the configuration channel line is changed regularly before the device is inserted. Typically, the voltage on the configuration channel line varies in a flip, e.g., from 5V to 0V and then from 0V to 5V; when the device is plugged in, the device will change the voltage state of the configuration channel line, where the voltage is pulled up or down to a default value. When the voltage is pulled up or pulled down to a preset default value, it is indicated that the USB-C interface has a device inserted. And determining the role of the device in the charging process through different voltage changes in the configuration channel line in the device. In general, a device in which a voltage in a channel line is pulled up to a high level is a charger, and a device in which a voltage in a channel line is pulled down to a low level is a mobile device. The default value is determined by the maximum power supply current of the charger, for example, when the maximum power supply current of the charger is 3A, the USB-C interface voltage of the charger is pulled up to 1.65V after the mobile device is connected.
The electronic equipment monitors the voltage state change of the configuration channel line, and when the electronic equipment detects voltage overturn, the electronic equipment determines that the mobile equipment is accessed through the USB-C interface and triggers the electronic equipment to start to communicate with the mobile equipment.
In another alternative embodiment, the electronic device may also detect that the mobile device has access to the USB-C interface by current detection or capacitive signal detection.
S11: and when the mobile equipment supports the first charging protocol, acquiring first charging power according to the content of the first handshake communication, and carrying out quick charging on the mobile equipment based on the first charging power.
It should be understood that the charging power includes a charging voltage and a charging current. Since the harness of the C-C data line can withstand a current of 5A at maximum, the charging current cannot exceed 5A.
When the mobile equipment supports the first charging protocol, the electronic equipment selects a current-voltage data set closest to the voltage and the current supported by the mobile equipment in the first charging protocol according to the power class, the voltage, the current and the first charging power supported by the mobile equipment in the first response information, and takes the current-voltage data set as the first charging power, so that the mobile equipment is charged according to the first charging power.
Illustratively, the first charging protocol is a PD protocol, wherein the PD protocol comprises: a total of four sets of current-voltage data sets of 5V/3A, 9V/2A, 15V/3A and 20V/5A. After the charger determines that the mobile phone supports the PD protocol, the charger selects 9V/2A power as the mobile phone to charge according to the information of supporting voltage of 12V and current of 5A in response information fed back by the mobile phone.
It should be understood that the mobile device needs to be quickly charged according to the first charging power in time after the first charging power is acquired. The mobile device is prevented from detecting the current and voltage information of the quick charge when the mobile device is overtime and displaying the quick charge identification, so that a user is misled to not perform the quick charge for the mobile device.
S12: and carrying out a plurality of second handshake communications with the mobile device according to a plurality of second charging protocols to judge whether a second target charging protocol compatible with the mobile device exists in the plurality of second charging protocols.
The second charging protocol is a charging protocol supported by the electronic device except the first charging protocol, and the second target charging protocol is a charging protocol supported by both the electronic device and the mobile device except the first charging protocol.
To obtain optimal charging power, the time consuming charging of the mobile device is reduced. And the electronic equipment sends one or more second handshake requests to the mobile equipment according to one or more second charging protocols while taking the first charging power as the mobile equipment for quick charging, so that a second target quick charging protocol compatible with the mobile equipment is obtained according to response information of the mobile equipment.
In an alternative embodiment, the performing a plurality of second handshaking communications with the mobile device according to a plurality of second charging protocols to determine whether there is a second target charging protocol compatible with the mobile device in the plurality of second charging protocols includes:
determining a communication sequence corresponding to each of the plurality of second charging protocols;
sequentially sending a second handshake request to the mobile equipment according to the communication sequence to acquire a second response signal fed back by the mobile equipment;
comparing the second response signal with a corresponding response signal standard in the second charging protocol;
determining that the plurality of second charging protocols exist in the second target charging protocol when the second response signals meet response signal standards in the corresponding second charging protocols;
the plurality of second charging protocols are absent from the second target charging protocol when the second response signal does not meet a response signal criterion in the second charging protocol.
The communication sequence is a sequence in which the preset mobile device and the electronic device carry out second charging protocol handshake communication. The communication sequence should be set comprehensively according to the application range of the charging protocol and the applicable device types, for example, the first of the preset communication sequences is the QC protocol provided by the high-pass, which is suitable for the mobile device carrying the high-pass chip; the second is SCP protocol provided by Hua, the third is FCP protocol provided by Hua, and the fourth is AFC protocol provided by Sanxingzhu, which is only applicable to Sanxingzhu brand mobile equipment; fifth is the VOOC protocol offered by OPPO corporation.
It should be appreciated that each process of the electronic device verifying whether the mobile device supports the second charging protocol is identical to the process of the electronic device verifying whether the mobile device supports the first charging protocol, except that the charging protocols used are different. For brevity of description, the process of verifying whether the mobile device supports the first charging protocol with reference to the electronic device will not be described in detail herein.
And verifying whether the mobile equipment supports a second charging protocol or not so as to acquire a second target charging protocol compatible with the mobile equipment, and further acquiring the optimal charging protocol of the mobile equipment through charging power comparison supported by the charging protocol. To avoid the mobile device fast charge limitation caused by a preset single charge protocol.
S13: and when the second target charging protocols exist in the plurality of second charging protocols, acquiring second charging power according to the content of second target handshake communication corresponding to the second target charging protocols.
When the mobile equipment has compatible second target charging protocols, the electronic equipment selects a current-voltage data set closest to the voltage and the current supported by the mobile equipment in the second target charging protocols according to the power class, the voltage and the current supported by the mobile equipment in each second response message and the corresponding second target charging protocols, and takes the current-voltage data set as second charging power, so that a plurality of second charging powers are obtained.
S14: and when the second charging power is larger than the first charging power, replacing the second charging power with the first charging power so as to perform quick charging on the mobile equipment.
And obtaining the maximum charging power through the comparison between the plurality of second charging powers and the first charging power. When the maximum charging power is the first charging power, continuing to perform quick charging by taking the first charging power as the mobile equipment; and when the maximum charging power is not the first charging power, replacing the maximum second charging power obtained by comparison with the first charging power, and carrying out quick charging on the mobile equipment.
Illustratively, hua is a handset compatible PD protocol and SCP protocol. After the charger is connected with the mobile phone, the PD protocol is executed, and the mobile phone is charged quickly by 9V/2A. And when the second charging protocol compatibility verification is carried out on the mobile phone, and the mobile phone is determined to support the SCP protocol, and the charging power of the mobile phone under the SCP protocol is 10V/2.25A, the charger increases 9V/2A to 10V/2.25A to carry out higher-power quick charging on the mobile phone.
By acquiring the maximum charging power, the electronic device can dynamically adjust the charging power of the mobile device, and the charging efficiency can be improved because the adjusted charging power is larger than the charging power before adjustment. And when the charging power is adjusted, the charging protocol between the charger and the mobile equipment is used for adjusting, and the power change can be safely processed while the charging power is provided, so that the safety of the charging process is ensured.
In an alternative embodiment, after the replacing the second charging power with the first charging power to fast charge the mobile device, the electronic device further performs operations including:
acquiring the battery electric quantity of the mobile equipment in real time, and comparing the battery electric quantity with a preset standard electric quantity;
and when the battery electric quantity reaches the standard electric quantity, adjusting the second charging power to be preset overshoot-preventing charging power.
Fast charging, while bringing about an improvement in charging efficiency, tends to cause the battery of the mobile device to be overcharged. The overcharge easily causes a battery capacity loss, performance degradation, and a safety risk of battery explosion, so the electronic device monitors the battery power of the mobile device in real time and compares the battery power with a preset standard power, and when the battery power reaches the standard power, the charging power is reduced to a preset overshoot-preventing charging power, so as to prevent the battery of the mobile device from being overcharged with high power.
For example, 5V/1A of anti-overshoot charging power and 95% of standard electric quantity are preset in the charger. When the mobile phone being charged is charged quickly at 9V/2A and the electric quantity just reaches 95%, the charger detects that the electric quantity of the mobile phone reaches the standard electric quantity and regulates the charging power from 9V/2A to 5V/1A.
Through mobile device's electric quantity monitoring, can avoid preventing mobile device's battery by high-power overcharge to avoid battery damage risk and extension battery life. And meanwhile, the standard electric quantity and the overcharge charging power are reasonably set, so that the charging speed still meets the charging requirement of a user while the service life of the battery is prolonged.
In an alternative embodiment, the electronic device further performs operations comprising:
when the mobile equipment does not support the first charging protocol, performing a plurality of third handshake communications with the mobile equipment according to the plurality of second charging protocols to judge whether a third target charging protocol supported by the mobile equipment exists in the plurality of second charging protocols;
when the third target charging protocols do not exist in the plurality of second charging protocols, charging the mobile equipment based on preset common charging power;
when the plurality of second charging protocols exist in the third target charging protocol, third charging power is obtained according to the content of third target handshake communication corresponding to the third target charging protocol;
and carrying out quick charging on the mobile equipment based on the third charging power.
Wherein the third target charging protocol is a charging protocol supported by both the electronic device and the mobile device in addition to the first charging protocol.
In order to avoid that the mobile device cannot realize quick charging due to the fact that a preset first charging protocol is different from a charging protocol supported by the mobile device.
