Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

At present, in a charging system composed of electronic equipment and a charger, along with the increase of charging time and the increase of charging power, the temperature of the charger and the charging interface of the electronic equipment rises, and the temperature rises to cause potential safety hazards to the charging interface, for example, plastic at the charging interface is easily heated and melted, or the port of the charging interface is burned, and the like. In addition, the temperature does not rise at the utmost speed when the charging interface is subjected to liquid inlet or short circuit, and whether the charging interface is subjected to liquid inlet or short circuit or not is judged in a temperature mode, so that the problem of untimely operation is also solved.

Especially in a fast charge system, fast charging is a method of accelerating the amount of electricity by increasing the charging power. At present, the mainstream fast charging mode includes a mode of increasing charging voltage, i.e., a high-voltage low-current mode such as a fast Charge (QC) protocol charging scheme, and another mode of increasing charging current, i.e., a low-voltage high-current mode such as a flash Charge (VOOC) protocol charging scheme. Whether the voltage or the current is increased, the charging power is increased, and then the temperature of the charging interface is rapidly increased, so that the safety of the charging interface is affected.

In order to improve the problem of poor safety of the charging interface, in the prior art, a Temperature sensor, such as a Negative Temperature Coefficient (NTC) thermistor, is usually disposed at a port of the charging interface, and when a Temperature value of the port is greater than a preset Temperature value, the charging current of the charger is reduced.

However, the temperature sensor has a certain distance from the port of the charging interface, and the accuracy and the sensitivity of the detection of the temperature sensor are low, so that the problem of over-temperature of the charging interface cannot be solved timely and effectively. In order to solve the above problem, in the embodiment of the present invention, a difference range between an output electrical parameter value of the charger and an input electrical parameter value in a battery of the electronic device is used to determine whether the output power of the charger needs to be reduced in time, so as to avoid the over-temperature problem of the charging interface.

As shown in fig. 1, fig. 1 shows a schematic structural diagram of a charging system. The charging system comprises a charger 110 and an electronic device 120, wherein the charger 110 is connected with the electronic device 120 through four buses: supply bus VBUS, data buses D + and D-, and ground GND. The charger 110 includes a first Micro Controller Unit (MCU) 112 for controlling the functions of the charger and a sampling circuit 111, such as a power sampling circuit, for obtaining the output electrical parameter values of the charger 110. The electronic device 120 includes a second MCU122 for controlling functions of the electronic device 120, a battery 124 for supplying power to the electronic device 120, an electricity meter 123, and a charging Integrated Circuit (IC) 121 for managing a charging process.

Based on the above charging system, embodiments of the present invention provide a charging method, which is applied to the electronic device 120 and the charger 110, respectively, and the charging method applied to the electronic device 120 and the charger 110 is described below. The electronic device 120 includes, but is not limited to, a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted terminal, a wearable device, a pedometer, and the like.

First, an embodiment of a charging method applied to an electronic device is described, and referring to fig. 2, fig. 2 is a schematic flowchart illustrating a charging method applied to an electronic device according to an embodiment of the present invention. The method comprises the following steps:

s201, under the condition that the charger is connected with the electronic equipment in a charging mode, the electronic equipment obtains a first output electrical parameter value of the charger.

After the charger is connected with the power supply and the charger is connected with the electronic equipment through the data line, the charger is connected with the electronic equipment in a charging mode, and the charger can charge the electronic equipment at the moment.

S202, the electronic equipment obtains a first target parameter value and a first input electrical parameter value of the battery of the electronic equipment.

The first target parameter value here refers to a predetermined threshold for defining a maximum difference between the output electrical parameter value of the charger and the input electrical parameter value of the battery of the electronic device.

S203, reducing the first output electrical parameter value of the charger under the condition that the difference value between the first output electrical parameter value and the first input electrical parameter value is larger than or equal to the first target parameter value.

The difference between the two is reflected by the loss of electric energy during the charging process, and the loss is usually converted into heat energy, i.e. the difference causes the temperature rise of the charging circuit and the charger.

Under the condition that the difference value is smaller than the first target parameter value, the electric energy loss in the previous charging process is less, namely the influence on the temperature rise of the charging circuit is less, and the temperature of the charging interface cannot be too high, so that the processing is not needed; otherwise, the output electrical parameter value of the charger needs to be reduced, so that the electric energy loss in the charging process is reduced.

The above S201 and S202 are not limited in sequence, and may also be executed in parallel, which is not limited in the present invention.

Specific implementations of the above steps will be described in detail below.

In the embodiment of the invention, the first output electrical parameter value of the charger is differentiated from the first input electrical parameter value of the battery of the electronic equipment, the obtained difference value reflects the electric energy lost in the electric energy transmission process, and the temperature rise of the charging interface is caused by the part of the lost electric energy, so that the larger the part of the electric energy is, the larger the temperature rise amplitude of the charging interface is, and under the condition that the obtained difference value exceeds the threshold of the target parameter value, the embodiment of the invention can timely adjust the electrical parameter value output by the charger, thereby timely reducing the temperature rise amplitude of the charging interface, avoiding the situation that the temperature of the charging interface is too high as much as possible, and ensuring the safety of the charging interface. In addition, under the condition of liquid inlet or short circuit of the charging interface, the two conditions can also cause larger electric energy loss, so that the method can adjust the output electrical parameter value of the charger in time under the condition, thereby reducing the influence of the liquid inlet or the short circuit on the charging system. In addition, the safe and efficient charging process is ensured by optimizing the communication instruction and the judgment condition of power adjustment, and the production cost of the charger and the electronic equipment is not additionally increased.

In order to ensure normal communication between the charger and the electronic device, after the charger establishes a charging connection with the electronic device, the charger needs to perform handshaking communication with the electronic device before the charger communicates with the electronic device. Handshake communication is an operation performed by two devices before communication is performed to confirm whether communication is possible between the two devices. In an application scenario in the embodiment of the present invention, since the chargers have multiple models, there may be a case where the models of the electronic device and the connected chargers do not match, and therefore, the authentication needs to be performed through handshake communication. Therefore, only if the handshake communication is successful, the charger can perform normal communication with the electronic device, that is, subsequent data transmission, such as transmission of the first output electrical parameter value, can be performed.

In other embodiments of the present invention, the first output electrical parameter value of the charger and the first input electrical parameter value of the battery of the electronic device are the same type of electrical parameter value, where the type of electrical parameter value may be any one of a current value, a voltage value and a power value.

The type of the electrical parameter value is mainly determined by the output condition of the charger, for example, in some cases, the output voltage of the charger is fixed and the output current is adjustable, and the electrical parameter value here may be a current value, because the current value can reflect the output power of the charger; similarly, under the condition that the output voltage of the charger is adjustable and the output current is fixed, the voltage value can reflect the output power of the charger; in addition, under the condition that the voltage and the current of the charger are both adjustable, the electrical parameter value can be a power value. Whichever type of electrical parameter value is used above, the purpose is to be able to reflect the output power of the charger and the input power of the battery of the electronic device.

The following describes specific implementations of the steps in the above embodiments.

First, a specific implementation of S201 is described.

In some embodiments of the present invention, the charger may obtain its own output electrical parameter value by sampling through its own internal electrical parameter sampling circuit, such as a current sampling circuit, a voltage sampling circuit, a power sampling circuit, and the like. The power sampling circuit may be an Analog-to-Digital Converter (ADC).

That is, S201 may be: the electronic equipment obtains a first output electrical parameter value sampled by the charger from the charger.

Further, in some embodiments, the first output electrical parameter value sampled within the charger may be stored within an MCU or other component of the charger capable of storing data. The electronic device may then actively read or otherwise transmit the previously saved first output electrical parameter value to the electronic device by the charger. By the method, the historical output electrical parameter values of the charger can be conveniently traced.

In order to control the charger to perform power reduction operation in time, related data needs to be frequently transmitted between the charger and the electronic device, and the related data can be sent to a target end, namely a charger end or an electronic device end, through an independent instruction. However, in order to reduce the number of instructions sent, the present invention further provides the following embodiments:

that is, when the charger and the electronic device handshake communication are successful, the process of S201 specifically includes: and acquiring a first output electrical parameter value carried in the latest reply information of the charger. That is, the charger replies each piece of information of the electronic device, and except the handshake information, the charger needs to carry the first output electrical parameter value of the charger. By the method, the quantity of information sent to the electronic equipment by the charger can be reduced, and the occupation of resources is reduced.

In addition, since the output electrical parameter value of the charger may become a set value, for example, 5V2A, in case of a handshake communication failure between the charger and the electronic device, in some embodiments, in case of the handshake communication, S201 may also be: in the case of a failure in handshake communication between the charger and the electronic device, the electronic device acquires an output set value of the charger. At this time, the electronic device can directly read the output set value of the charger stored in advance.

The above is a specific implementation of S201, and a specific implementation of S202 is described below.

In other embodiments of the present invention, the electronic device may sample the first input electrical parameter value of the battery through a charging IC or a fuel gauge provided therein.

That is, S202 may be: the electronic device may directly sample and obtain the first input electrical parameter value in the above manner.

Furthermore, in some embodiments, the MCU or other component capable of storing data of the electronic device may further obtain the first input electrical parameter value sampled by the charging IC or the fuel gauge through I2C (Inter-Integrated Circuit) communication, and then the electronic device may directly obtain the saved first input electrical parameter value. The method can facilitate the follow-up tracing of the historical input electrical parameter values of the electronic equipment.

Since the original temperature values of the charging circuit are different in different charging states of the electronic device, for example, when the charging time has reached 1h and the charging time has reached 5min, the temperature of the charging circuit when the charging time is 1h should be higher than the temperature of the charging circuit when the charging time is 5 min. And based on the temperature value of different charging lines, the same temperature rise then can produce different effects, for example under the very high condition of charging line temperature, then the temperature rise that can tolerate can be lower, that is to say that first target parameter value should set up less, and the temperature of charging line is lower under the condition, then the temperature rise that permits can be higher, therefore the great that first target parameter value can set up.

Based on the above situation, in other embodiments of the present invention, the process of the electronic device obtaining the target parameter value threshold in S202 may include:

the electronic equipment acquires the charging state of the electronic equipment; the charging state comprises characteristic parameters of the environment where the electronic equipment is located and the electric quantity of the electronic equipment; the characteristic parameter may include a temperature value, etc.

The electronic equipment takes a threshold value corresponding to the charging state on a pre-acquired electrical parameter loss curve as a first target parameter value; the electrical parameter loss curve is a corresponding curve of the charging state and the threshold value.

In this embodiment, corresponding threshold values are set for different charging states of the electronic device, so that the first target parameter value can be selected according to the temperature rise allowed by the different charging states, the time for reducing power of the charger is controlled more accurately, and the safety of the charging interface is improved.

Before the electronic equipment is on the market, the electrical parameter loss curve is drawn according to a test result of the charger on the real-time charging power loss of the electronic equipment, wherein the charging power loss is a difference value between an output electrical parameter value of the charger and an input electrical parameter value of a corresponding battery, a real-time test scene is shown in table 1, and table 1 is a test scene table of the charging power loss.

TABLE 1 test scenario table for charging power loss

Based on the above embodiments, in some embodiments, the electrical parameter loss curve is typically stored within the electronic device. In this case, the electronic device may determine the first target parameter value directly according to the self-charging state and the self-stored electrical parameter loss curve.

In addition, in other embodiments, the electrical parameter loss curve may also be stored in the charger, and in this case, when the charging method is applied to the electronic device, the charger may send the electrical parameter loss curve to the electronic device, and the electronic device determines the target parameter value threshold.

The above is a specific implementation of S202, and a specific implementation of S203 is described below.

In the process of controlling to decrease the output electrical parameter value of the charger, the following embodiment may be specifically adopted, and in this embodiment, the process of decreasing the first output electrical parameter value in S203 may be implemented in the following manner:

the electronic device reduces the first output electrical parameter value to a preset output value.

And in the process that the charger charges the electronic equipment according to the preset output value, the electronic equipment acquires a second output electrical parameter value of the charger, a second target parameter value threshold of the electronic equipment and a second input electrical parameter value of a battery of the electronic equipment.

And the electronic equipment controls the charger to stop charging when the difference value between the second output electrical parameter value and the second input electrical parameter value is greater than or equal to the second target parameter value threshold.

In this embodiment, the first output electrical parameter value of the charger is first reduced, and in this case, it can be ensured that the difference value in the subsequent charging process does not reach the first target parameter value any more, and at the same time, it can be ensured that the charging process is not suspended, thereby ensuring the efficiency and safety of the user charging process.

Based on the above embodiment, after controlling the charger to stop charging, the user may inquire about the reason for the power failure through the electronic device, solve the problem, and restart charging after the problem is solved. Namely, in a further embodiment, after the controlling the charger to stop charging, the method may further include: when the electronic device stops charging, the charger is controlled to resume charging if the electronic device receives an input instruction for recharging. By the mode, normal charging after potential safety hazards of the charger are solved can be guaranteed.

In the process of controlling to decrease the output electrical parameter value of the charger, another embodiment may also be adopted, and in this embodiment, the process of decreasing the first output electrical parameter value in S203 may also be:

the electronic equipment controls the charger to stop charging.

And after the time for stopping charging reaches a second preset disconnection time period, the electronic equipment acquires a third output electrical parameter value of the charger, a third target parameter value threshold of the electronic equipment and a third input electrical parameter value of a battery of the electronic equipment.

And the electronic equipment controls the charger to stop charging again under the condition that the difference value between the third output electrical parameter value and the third input electrical parameter value is greater than or equal to the third target parameter value threshold.

Based on the above embodiment, after the charger is controlled to stop charging for a period of time, the temperature of the charging line generally drops, and in this case, the safety of the charging line can be ensured by starting the high-power charging again. The mode can ensure that the charger can be quickly charged through high power all the time, thereby improving the charging efficiency. However, after the charging is stopped for a period of time, if the potential safety hazard still exists, the charger needs to be controlled again to stop charging, so as to ensure the safety of the charger.

When the charger stops charging for the second time, the charger cannot be automatically restarted, and the charger can be controlled to resume charging after receiving the input recharging command. Here, the instruction of recharging is an instruction input after the user inquires about the reason of the power failure and solves the problem through the electronic device. By the mode, normal charging after potential safety hazards of the charger are solved can be guaranteed.

In addition, in some other embodiments, the above-mentioned re-controlling the charger to stop charging may be to lock the power output of the charger, and such locking operation may disable charging even if a re-charging instruction is received, and only after the charger is unplugged from the power supply and then plugged into the power supply again, the charger may be unlocked to perform charging. This way the safety of the charging circuit can be further improved.

It should be noted that the second output electrical parameter value and the third output electrical parameter value are both the same as the first output electrical parameter value in terms of parameter type, and may be obtained in the same obtaining manner. The second input electrical parameter value and the third input electrical parameter value are the same as the first input electrical parameter value in parameter type, and can be acquired by the same acquisition mode. The second target parameter value threshold and the third target parameter value threshold can be obtained in the same obtaining mode as the first target parameter value. For avoiding repetition, the process of obtaining the second output electrical parameter value and the third output electrical parameter value, the second input electrical parameter value and the third input electrical parameter value, and the second target parameter value threshold and the third target parameter value threshold is not described herein again.

In addition, the invention also provides the following embodiments:

the embodiment of the invention provides a scheme capable of updating and optimizing the loss curve of the electrical parameter. That is, in still other embodiments of the present invention, after S203, the method may further include:

the electronic equipment feeds the difference back to the data server; so that the data server analyzes the received difference and optimizes the loss curve of the electrical parameters according to the analysis result. Wherein the data server may be a big data server.

In this embodiment, in the actual use process of the electronic device, the charger may obtain the charging loss value in each stage, such as the constant current stage and the constant voltage stage, when the charger charges the electronic device, and the electronic device may feed the data back to the big data end after obtaining the value, and further optimize the loss curve of the electrical parameter through statistical analysis of the big data. The method can continuously improve the loss curve of the electrical parameters, and further improve the accuracy of charger control.

An embodiment of a charging method applied to a charger is described below, and referring to fig. 3, fig. 3 is a schematic flow chart illustrating a charging method applied to a charger according to an embodiment of the present invention. The method comprises the following steps:

s301, under the condition that the charger is connected with the electronic device in a charging mode, the charger obtains a first output electrical parameter value of the charger.

S302, the charger obtains a first target parameter value and a first input electrical parameter value of a battery of the electronic device.

S303, the charger adjusts the first output electrical parameter value of the charger when the difference value between the first output electrical parameter value and the first input electrical parameter value is larger than or equal to the first target parameter value.

The above S301 and S302 are not limited in sequence, and may also be executed in parallel, which is not limited in the present invention.

In the embodiment of the invention, the first output electrical parameter value of the charger is differentiated from the first input electrical parameter value of the battery of the electronic equipment, the obtained difference value reflects the electric energy lost in the electric energy transmission process, and the temperature rise of the charging interface is caused by the part of the lost electric energy, so that the larger the part of the electric energy is, the larger the temperature rise amplitude of the charging interface is, and under the condition that the obtained difference value exceeds the threshold of the target parameter value, the embodiment of the invention can timely adjust the electrical parameter value output by the charger, thereby timely reducing the temperature rise amplitude of the charging interface, avoiding the situation that the temperature of the charging interface is too high as much as possible, and ensuring the safety of the charging interface. In addition, under the condition of liquid inlet or short circuit of the charging interface, the two conditions can also cause larger electric energy loss, so that the method can adjust the output electrical parameter value of the charger in time under the condition, thereby reducing the influence of the liquid inlet or the short circuit on the charging system. In addition, the present embodiment ensures a safe and efficient charging process by optimizing the communication command and the determination condition of power adjustment, without increasing the production cost of the charger and the electronic device.

The sampling manner of the charger can be referred to in the embodiment of the charging method applied to the electronic device, and is not described herein again. S301 may be: the charger samples and obtains a first output electrical parameter value of the charger through the circuit.

For a sampling manner of the electronic device, reference may be made to an embodiment of a charging method applied to the electronic device, and details are not described herein. The above S302 may be that the electronic device may send the sampled first input electrical parameter value to the charger.

Furthermore, in some embodiments, the MCU or other component capable of storing data of the electronic device may also obtain the first input electrical parameter value sampled by the charging IC or the fuel gauge through I2C (Inter-Integrated Circuit) communication, and then the charger may read or send the first input electrical parameter value saved before to the charger by the electronic device. The method can facilitate the follow-up tracing of the historical input electrical parameter values of the electronic equipment.

For the aforementioned purpose of reducing the number of transmitted instructions, in other embodiments of the present invention, in case that the charger and the electronic device handshake communication is successful, the process of S302 may be: and acquiring a first target parameter value and a first input electrical parameter value carried in a command which is newly sent by the electronic equipment. That is, each instruction sent by the electronic device to the charger needs to carry the first target parameter value and the first input electrical parameter value of the battery except the handshake instruction. By the mode, the number of the instructions sent to the charger by the electronic equipment can be reduced, and the occupation of resources is reduced.

For example, in some embodiments, since the electronic device sends a first instruction for adjusting the output power of the charger to the charger according to the level of the electric quantity of the electronic device during the charging process of the charger, the electronic device may obtain a first target parameter value of the electronic device and a first input electrical parameter value of the battery, and send the obtained first target parameter value and the first input electrical parameter value to the charger together when sending the first instruction to the charger. For example, the electronic device requests the charger output 20V2.25A, the first input electrical parameter value of the current battery is 5V1.2A, the first target parameter value is 20W, and the first command sent is 20V +2.25A +6W + 20W. Of course, due to the difference between the types of the chargers, the electronic device may only need to adjust the current value or the voltage value when requesting the output of the charger, for example, the electronic device requests the output of the charger to be 2.25A, and then the first command is sent to be 2.25A +6W + 20W.

In other embodiments, in order to detect whether the charger has an abnormal fault such as an overvoltage, an over-temperature, or a micro short circuit, the electronic device sends a second instruction for detecting the state of the charger to the charger, and the second instruction also carries the acquired first target parameter value and the first input electrical parameter value. For example, the current first input electrical parameter value of the battery is 5V4A, and the second command is sent to be +30W of the parameter value required for detecting the charger, where the parameter value required for detecting the charger may be power, for example, the theoretical output of the charger should be 9V1A or 8V2A, and the parameter value required for detecting the charger is 9W or 16W.

The present invention does not limit the content originally contained in each command sent by the electronic device to the charger and the expression of the first input electrical parameter value carried by the command, for example, in the case that the first input electrical parameter value is input power, it may be represented by a form of power, such as 6W, or by a form of current voltage, such as 5 V1.2A.

In other embodiments of the present invention, the process of acquiring the first target parameter value by the charger in S302 may include:

the charger acquires a charging state of the electronic device.

The charger takes a threshold value corresponding to the charging state on a pre-acquired electrical parameter loss curve as a first target parameter value; the electrical parameter loss curve is a corresponding curve of the charging state and the threshold value.

In some embodiments, the electrical parameter loss curve is typically stored within the electronic device. In this case, the electronic device may determine the first target parameter value in advance according to the charging state of the electronic device and the electrical parameter loss curve stored in the electronic device, and then send the first target parameter value to the charger, or the electronic device may send the electrical parameter loss curve and the charging state of the electronic device to the charger, and the charger determines the first target parameter value.

In addition, in other embodiments, the loss curve of the electrical parameter may also be stored in the charger, and the electronic device may send its charging status to the charger, and the charger determines the first target parameter value. The specific manner in which the present invention is employed is not limited.

That is, in the case that the loss curve of the electrical parameter is saved in the charger, in order to reduce the number of sent instructions, in another embodiment of the present invention, S302 may further be: and acquiring the charging state of the electronic equipment and the first input electrical parameter value carried in the latest transmitted instruction of the electronic equipment. That is, each instruction sent by the electronic device to the charger carries the charging state of the electronic device and the first input electrical parameter value of the battery, except the handshake instruction. Since in the foregoing embodiment, there is a corresponding relationship between the charging state of the electronic device and the threshold, the charger can determine the first target parameter value according to the charging state of the electronic device and the electrical parameter loss curve obtained in advance by the charger.

Since the charger and the electronic device cannot exchange information through a private protocol, that is, cannot communicate with each other, in the case that the charger and the electronic device fail to communicate with each other, the first output electrical parameter value of the charger may be in the state of 5V2A, in this case, in order to enable the charger to obtain the first input electrical parameter value of the battery of the electronic device, the following scheme may be adopted:

in still other embodiments of the present invention, the process of acquiring a first input electrical parameter value of a battery of an electronic device in S302 may include:

in the event of a failure of the charger to handshake communication with the electronic device, the charger obtains a level value on a data bus of the electronic device.

And the charger determines the first input electrical parameter value corresponding to the level value according to the preset corresponding relation between the level value and the first input electrical parameter value.

In this embodiment, the MCU of the electronic device controls the output level at the D +/D-of the data bus interface thereof according to the preset corresponding relationship between the level value and the first input electrical parameter value, so as to inform the charger of the first input electrical parameter value in a single direction. At this time, since the electronic device and the charger cannot communicate with each other, and the level value usually cannot represent the charging state of the electronic device, in this case, the charger may adopt the first target parameter value set in advance.

The above is a specific implementation manner of S302, a specific implementation manner of S303 in this embodiment is similar to that of S203, and for avoiding repetition, details are not described here again.

In addition, the invention also provides the following embodiments:

in the embodiment of the charging method applied to the charger, after S303, the charger may also feed back the difference to the data server; so that the data server analyzes the received difference and optimizes the loss curve of the electrical parameters according to the analysis result.

In this embodiment, in the actual use process of the electronic device, the charger may obtain the charging loss value in each stage when the charger charges the electronic device, for example, the charging loss value in the constant current stage and the constant voltage stage, and transmit the value back to the electronic device in real time, and the electronic device may feed back the data to the big data end, and further optimize the electrical parameter loss curve through statistical analysis of the big data. The method can continuously improve the loss curve of the electrical parameters, and further improve the accuracy of charger control.

Since the operation of controlling the charger to power down after the difference is greater than or equal to the first target parameter value belongs to a remedial operation taken to avoid a charger failure, rather than a normal charge power control operation, the electronic device generally needs to acquire the reason for the operation. Therefore, in other embodiments of the present invention, in a case where the charging method is applied to a charger, after S303, the method may further include:

An adjusting module 403, configured to adjust the first output electrical parameter value of the charger if the difference between the first output electrical parameter value and the first input electrical parameter value is greater than or equal to the first target parameter value.

In the embodiment of the invention, the first output electrical parameter value of the charger is differentiated from the first input electrical parameter value of the battery of the electronic equipment, the obtained difference value reflects the electric energy lost in the electric energy transmission process, and the temperature rise of the charging interface is caused by the part of the lost electric energy, so that the larger the part of the electric energy is, the larger the temperature rise amplitude of the charging interface is, and under the condition that the obtained difference value exceeds the threshold of the target parameter value, the embodiment of the invention can timely adjust the electrical parameter value output by the charger, thereby timely reducing the temperature rise amplitude of the charging interface, avoiding the situation that the temperature of the charging interface is too high as much as possible, and ensuring the safety of the charging interface. In addition, under the condition of liquid inlet or short circuit of the charging interface, the two conditions can also cause larger electric energy loss, so that the device can also adjust the output electrical parameter value of the charger in time under the condition, thereby reducing the influence of the liquid inlet or the short circuit on the charging system.

The electronic device includes, but is not limited to, a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted terminal, a wearable device, a pedometer, and the like.

In addition, in order to ensure normal communication between the charger and the electronic device, after the charger establishes a charging connection with the electronic device, the charger needs to perform handshake communication with the electronic device before the charger communicates with the electronic device.

In an application scenario in the embodiment of the present invention, since the chargers have multiple models, there may be a case where the models of the electronic device and the connected chargers do not match, and therefore, the authentication needs to be performed through handshake communication. Therefore, only if the handshake communication is successful, the charger can perform normal communication with the electronic device, that is, subsequent data transmission, such as transmission of the first output electrical parameter value, can be performed.

In still other implementation manners of this embodiment, in the charger, the output electrical parameter value of the charger itself may be obtained by sampling through an electrical parameter sampling circuit arranged in the charger itself, such as a current sampling circuit, a voltage sampling circuit, a power sampling circuit, and the like.

By the method, the quantity of information sent to the electronic equipment by the charger can be reduced, and the occupation of resources is reduced.

Furthermore, since the first output electrical parameter value of the charger may become a set value, for example, 5V2A, in case of a handshake communication failure between the charger and the electronic device, in some embodiments, the first obtaining module 401 may further be configured to: and acquiring an output set value of the charger under the condition that the communication between the charger and the electronic equipment is failed.
