Description

A charging method, mobile terminal and charger

technical field

The invention relates to the field of electronic technology, in particular to a charging method, a mobile terminal and a charger.

Background technique

With the development of fast charging technology for smart terminals, the market's demand for fast charging functions is increasing. Fast charging can be fully charged in a shorter time, bringing consumers a better experience. Common fast charging technologies for smart mobile terminals such as mobile phones include:

The first type is low-voltage high-current fast charging technology, which uses a low-voltage high-current method based on 5V, and uses a custom protocol for communication and interaction between the mobile terminal and the adapter. After the communication is successfully matched, the fast charging of the mobile phone is started. By pouring the large current output by the charger directly into the battery, not only can a faster charging speed be obtained, but also because only the battery is the main heat source on the mobile phone side during charging, the whole machine has no obvious temperature rise, and the overall experience is relatively good.

However, since this solution requires the USB interface of the mobile terminal to support a current greater than 2A, and the overcurrent capability of the Micro USB interface recommended by the national standard is only 2A, a specially customized USB interface is required to use this solution. In addition, since the mobile phone terminal and the adapter terminal adopt a self-defined communication method, a relatively closed fast charging system is formed. When using a non-standard charger, the mobile phone terminal can only perform conventional charging according to the specification of 5V/2A. Carrying the original charger at any time can realize fast charging, and the versatility is relatively limited.

That is to say, due to the completely different implementation principles and methods of fast charging technology, there are various chargers that support fast charging and mobile phones that support different fast charging modes. Users only use standard chargers during use. Fast charging can only be achieved when connected to mobile phones, which affects the rapid popularization of fast charging technology to a certain extent.

The second type is high-voltage charging technology. On the basis of the existing USB interface, the total power of the input end of the mobile terminal is increased by increasing the output voltage of the adapter. On the mobile terminal side, a switch IC that supports step-down is used to convert the high-voltage and small current at the input end. It is the low voltage and high current required by the battery terminal.

This technology is the mainstream fast charging technology in the current market. Since it is a technology improved on the existing charging hardware system technology, it can be directly compatible with the existing conventional chargers and charging lines, and the versatility and compatibility are better. Okay, so it has the support of the majority of terminal manufacturers. In addition, the communication protocol of the existing high-voltage charging technology is relatively unified, all based on or derived from the QC2.0 communication protocol led by Qualcomm, so that high-voltage chargers from different manufacturers can be used interchangeably. , the entire fast charging system is more versatile. However, since the power conversion IC needs to be placed on the mobile phone, when the charging current is large, the temperature rise of the whole device is relatively high, and the charging experience is relatively poor.

The above examples illustrate the two mainstream fast charging technology solutions currently on the market, each with its own advantages and disadvantages. The first one has better charging speed and experience, but the system is relatively closed and the compatibility is relatively poor. The second type is more versatile, but limited by the temperature rise of the system during charging, the charging current cannot be too high, and the experience of fast charging is relatively poor.

To sum up, among the existing fast charging technologies for mobile terminals such as mobile phones, there is no one that can better meet the needs of users for fast charging, bring users a good charging experience, and better expand compatibility, which is conducive to rapid market promotion. charge technology.

detailed description

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

The present invention aims at the problem that the fast charging scheme in the existing technology cannot better meet the needs of users for fast charging and has versatility, and provides a variety of solutions, specifically as follows:

Embodiment one

As shown in Figure 1, the charging method provided by Embodiment 1 of the present invention includes:

Step 11: When it is detected that the charger connected to the mobile terminal is a preset charger, switch to the first charging circuit of the mobile terminal to charge the battery of the mobile terminal.

Wherein, the preset charger may be an original charger, and the first charging circuit may be a direct charging circuit. The mobile terminal and the charger can be connected through a double-sided pluggable TypeC interface.

Specifically, before step 11, the method further includes: after turning on the second charging circuit to start charging the battery of the mobile terminal, detecting whether the charger connected to the mobile terminal is a preset charger.

Step 12: Otherwise, charge the battery of the mobile terminal through the second charging circuit of the mobile terminal.

That is, when it is detected that the charger connected to the mobile terminal is not a preset charger, the second charging circuit of the mobile terminal continues to be used to charge the battery of the mobile terminal.

Correspondingly, the second charging circuit may be a step-down charging circuit.

Wherein, the charging power of the first charging circuit is greater than the charging power of the second charging circuit.

Specifically, the step of detecting whether the charger connected to the mobile terminal is a preset charger includes: sending an identity authentication instruction to the charger; receiving identity type information fed back by the charger according to the identity authentication instruction; Judging whether the charger is a preset charger according to the identity type information.

That is, two-way communication can be performed between the mobile terminal and the charger, thereby controlling a circuit for charging the battery of the mobile terminal.

Wherein, when it is detected that the charger connected to the mobile terminal is a preset charger, the step of switching to the first charging circuit of the mobile terminal to charge the battery of the mobile terminal includes: detecting that the charger connected to the mobile terminal is When the charger is preset, send a corresponding power request to the charger, turn on the first charging circuit, disconnect the second charging circuit, and charge the battery of the mobile terminal through the first charging circuit .

That is, after determining which circuit to use for charging, the mobile terminal requests corresponding power from the charger.

In order to be more intelligent, the solution provided by the embodiment of the present invention further includes: when using the first charging circuit of the mobile terminal to charge the battery of the mobile terminal, if the preset system parameter value of the mobile terminal exceeds the preset threshold, then switch off Returning to the second charging circuit to charge the battery of the mobile terminal.

That is, if there is an abnormality during the charging process using the direct charging circuit (for example, the battery voltage value, the channel current value, the port temperature rise value, etc. exceed the normal threshold, or it can be within the normal range), then switch back to the step-down charging circuit.

The charging method provided by Embodiment 1 of the present invention (the mobile phone terminal, which can be connected to the charger terminal through a charging cable) will be further described below.

At present, most of the fast charging solutions on the mobile phone use high-voltage fast charging. By increasing the output voltage of the charger from the conventional 5V to 9V or 12V, a large power is obtained to charge the mobile phone. On the mobile phone, it is necessary to use a charging IC to The voltage of the charger is lowered to the battery voltage. In this way, a charging IC is required on the mobile terminal side, and this IC is the main heat source IC on the motherboard side, which will cause serious heating of the mobile phone during charging. Another fast charging solution is the low-voltage direct charging method. The charger directly outputs the adjusted voltage and current to charge the battery. This method has a better charging experience, but the charger needs to use a specific charger, which has poor compatibility.

As shown in Figure 2, the solution provided by the embodiment of the present invention is compatible with the low-voltage direct charging (direct charging circuit-switch S2 path) and high-voltage fast charging (step-down charging circuit-switch S1+charging circuit path) solutions at the same time. , when the user uses the original charger, the low-voltage direct charging scheme will be adopted by default. This method charges quickly and the temperature rise is small. When the user goes out without the original charger, he can use the most common high-voltage charger on the market for the mobile phone. Also realize the fast charging function.

Embodiment two

As shown in Figure 3, the charging method provided by Embodiment 2 of the present invention includes:

Step 31: Receive the power request sent by the mobile terminal connected to the charger.

Specifically: receiving the identity authentication instruction sent by the mobile terminal; feeding back the identity type information of the charger to the mobile terminal according to the identity authentication instruction; receiving the power request sent by the mobile terminal according to the identity type information .

Step 32: Delivering a corresponding charging voltage and charging current to the mobile terminal according to the power request.

That is, two-way communication can be performed between the charger and the mobile terminal, and then the corresponding charging circuit is controlled to charge the battery of the mobile terminal.

The charging method provided by Embodiment 2 of the present invention (the charger terminal, which can be connected to the mobile phone terminal through a charging cable) will be further described below.

The current charger only has the power conversion circuit and the most basic control circuit inside. The control circuit can only passively receive the signal from the mobile phone and adjust the most basic output voltage on the hardware. Terminal information and charger output control and adjustment. Such as common 5V chargers in the market, high-voltage fast charge chargers (9V 2A and other specifications), and low-voltage high-current chargers (such as 5V 4A chargers).

In addition, the fast charging technologies on the market are not compatible with other charging handshake protocols, which makes it very inconvenient for users to use. However, the solution provided by the embodiment of the present invention integrates high-voltage fast charging and low-voltage direct charging into one charger. As shown in Figure 2, charger compatibility is improved.

The charging method provided by the embodiment of the present invention will be further described below in conjunction with both the mobile terminal and the charger.

In order to overcome the deficiencies of the prior art, the embodiment of the present invention provides a charging method, which can be realized by the following fast charging system:

As shown in Figure 2, the system is based on a TypeC interface that supports 5A overcurrent capability, including an adapter (charger) that supports continuously adjustable output voltage from 3.5V to 9V and supports two charging paths (path 1-switch S1+charging circuit path; path 2-path of switch S2) mobile terminal.

The adapter side supports continuously adjustable voltage from 3.5V to 9V. In this voltage range, the voltage can be adjusted in smaller steps such as 20mv gears. The output current can be supported up to 5A based on the Type C interface, and the output current can be Adjust in smaller steps such as 50mA;

When the user is using the original charger, the mobile phone can communicate with the charger through the Type C interface, using a custom protocol based on USB PD (USB interface specification). After the matching is successful, the mobile phone will switch the charging channel to channel 2 , the adapter outputs corresponding low-voltage high-current information according to the voltage and current information requested by the mobile phone, and directly charges the battery through path 2 to realize low-voltage high-current charging.

When the user uses a non-original charger, if it is a charger that supports high-voltage fast charging, the mobile phone can actively request a high-voltage signal, and switch the charging path on the mobile terminal side to path 1. There is a support on this path For high-voltage and high-current charging charging ICs, the high-voltage communication protocol can use protocol specifications based on USB PD or QC2.0 (Quick Charge Technology 2.0 released by Qualcomm).

When the user uses a common charger, it can be compatible with conventional charging at the 5V voltage level.

When the user uses the adapter to charge other mobile phones, the adapter can output the corresponding voltage according to the request of the mobile phone. Since the adapter also supports high-voltage output, it can be better integrated into the fast charging system.

Through the above improvements, not only the advantages of low-voltage and high-current charging can be brought into play, but also the versatility of high-voltage charging can be inherited, so that the system’s fast charging solution not only has better performance, but also greatly expands its versatility.

Further, on the charger side:

The charger side integrates a power conversion circuit, a protocol and a control circuit, which can convert the mains power into a commonly used DC voltage.

The output voltage specification of the charger is: 3.5V--9V continuous voltage can be adjusted, the adjustment step between 3.5V and 5V can be relatively accurate and small, reaching about 10mv, and the voltage adjustment step between 5V and 9V is about 100mv.

Output current: It can support up to 5A in the range of 3.5V to 5V, and the maximum output current in the range of 5V to 9V can support up to 3A, and the output current can be adjusted in relatively small steps such as 50mv.

Charging Cable:

The charging cable and interface can use a TypeC interface that supports 5A overcurrent capability, and this interface will become more popular and universal in the future.

Mobile terminal:

The design of the mobile phone needs to support two charging paths, as shown in Figure 2, the path where the switch S2 is located and the path of the switch S1. There is a charging IC on the S1 path. The charging IC supports 5V and 9V high-voltage and high-current charging; the path S2 High current can be directly fed into the battery.

The main implementation of this system depends on the charger and the mobile phone terminal. When the user uses the original charger, the default method is to charge the battery directly with low voltage and high current. way to charge.

In addition, since the mobile phone is compatible with both low-voltage direct charging and high-voltage fast charging, the entire charging system needs to define a set of protocols, which are used to realize the data communication between the mobile phone and the charger, and control and adjust through the mobile phone The output voltage and current of the charger.

Optionally, the low-voltage direct charging protocol is implemented using a defined set of closed protocol systems to ensure charging safety, and the high-voltage communication protocol is implemented using the most mainstream Qualcomm QC2.0 protocol in the market to achieve the purpose of expanding compatibility.

Specifically, as shown in Figure 4, the system includes: charger, charging cable, charging interface, anti-reverse insertion MOS (insulated gate field effect transistor), OVP IC (overvoltage protection circuit), PMI (control charging circuit) 1, Switch 1, Switch 2, Battery, Fuel Gauge IC, AP1 (CPU on mobile phone), PMI 2, USB Switch, MCU (Charger Microprocessor) and AP2 (Computer);

Among them, the path where the anti-reverse insertion MOS, OVP IC, PMI 1 and switch 1 are located is equivalent to the above-mentioned path 1; the path where the switch 2 is located is equivalent to the above-mentioned path 2.

The path where the USB switch and MCU are located is a signal charging path; the path where the USB switch and AP2 are located is a signal path. These two pathways are consistent with existing ones and will not be described in detail here.

The corresponding usage process is as follows:

The default output capacity of the charger is 5V/2A, D+/D- short circuit (DCP, dedicated charging port mode), the default direct charging path switch (switch 2 in the picture) on the mobile phone is off, and the USB switch connects D+/D- by default to the PMI 2 side.

After the charger is connected to the mobile phone, normal 5V charging is turned on by default, and PMI 2 performs BC1.2 detection based on D+/D- and the charger to judge the status of the charger.

When the PMI 2 on the system side detects that it is a DCP, switch the USB switch to the MCU side, and output a predefined command signal code0 on D+/D- through the MCU control. After the D+/D- side of the charger detects the code0 command , the MCU1 at the charger end disconnects the D+/D- connection of the TA (travel charger) end, so that D+ and D- are independently opened on the entire charging path.

On the D+/D- channel, the MCU at the mobile phone end and the MCU1 at the charger end use a predefined communication protocol for handshake judgment, and detect the initial state of the system (port temperature rise, channel impedance, ambient temperature, battery status, etc.). After the test is passed, the fuel gauge reports the battery voltage information, and the AP (CPU on the mobile phone) notifies the MCU of the information. The MCU requests the charger to adjust the output voltage and current according to the current state of the battery. The mobile phone detects the voltage on the board. When the output target value is reached, the MCU controls the direct charge path to be turned on to charge the battery quickly.

During the fast charging process, real-time polling monitors the status of battery voltage, channel current, and port temperature rise. When an abnormal state occurs, the channel is switched to the normal 5V charging channel in time, and the TA output is adjusted back to the default value. When the charging reaches the constant voltage conversion point, use the step (step) method to gradually reduce the charging current gear, and when the current reaches about 2A, switch the charging path to the normal path (above path 1), and turn off the direct charging path (Path 2 above), the judgment of the final charging cut-off is realized by the PMI1 part.

If the low-voltage fast charge handshake between the mobile phone end and the charger end fails, control PMI 1 to perform QC handshake communication with the charger, and start regular QC charging.

Among them, the low-voltage direct charging protocol is realized through the D+/D- channel of the USB port; however, the mobile phone end and the charger end use a similar I2C (two-wire serial bus protocol) for data transmission through the D+/D- channel. The terminal detects the battery voltage and status information, and then communicates to control the output of the charger.

It can be seen from the above that the solution provided by the embodiment of the present invention uses the fast charging system so that the user can obtain a better charging experience through the low-voltage and high-current mode when using the original charger, and when using a non-original charger, the mobile phone terminal It can still support high-voltage and high-current charging, and can also achieve fast charging. If the user is using a conventional 5V charger, proceed with conventional charging.

That is, the charger provided by the embodiment of the present invention can support low-voltage and high-current output when matching the original mobile phone, and can also output high voltage to the mobile terminal for fast charging based on Qualcomm's high-voltage fast charging protocol when matching the mobile phone that supports high-voltage charging; It can not only significantly improve the charging speed and experience of users when charging, but also expand the fast charging system, which greatly improves the market compatibility and is more conducive to the development of fast charging technology.
