In some embodiments, the circuit board may be fixed within the rear case 11. Specifically, the circuit board may be screwed to the rear case 11 by screws, or may be snap-fitted to the rear case 11 by means of a snap. It should be noted that the way of fixing the circuit board to the rear shell 11 specifically is not limited to this, and other ways, such as a way of fixing by a snap and a screw together, are also possible. In which a battery is mounted in the rear case 11, and the battery 11 is electrically connected to a circuit board to supply power to the electronic device 10. The rear case 11 may serve as a battery cover of the battery. The rear case 11 covers the battery to protect the battery, reducing damage to the battery due to collision, dropping, etc. of the electronic apparatus 10.

The electronic device 10 may include input-output circuitry, which may be disposed on a circuit board. The input-output circuitry may be used to enable the electronic device 10 to enable input and output of data, i.e., to allow the electronic device 10 to receive data from external devices and also to allow the electronic device 10 to output data from the electronic device 10 to external devices. The input-output circuit may further include a sensor.

A user may enter commands through the input-output circuitry to control operation of the electronic device 10, and may use output data of the input-output circuitry to enable receipt of status information and other outputs from the electronic device 10.

The electronic device 10 also includes a charging circuit. The charging circuit may charge a cell of the electronic device 10. The charging circuit may be used to further regulate the charging voltage and/or charging current input from the adapter to meet the charging requirements of the battery.

The electronic device 10 is configured with a charging interface, which may be, for example, a USB 2.0 interface, a Micro USB interface, or a USB TYPE-C interface. In some embodiments, the charging interface may also be a lightning interface, or any other type of parallel or serial interface capable of being used for charging. The charging interface is connected with the adapter through a data line, the adapter acquires electric energy from mains supply, and the electric energy is transmitted to the charging circuit through the data line and the charging interface after voltage conversion, so that the electric energy can be charged into the battery cell to be charged through the charging circuit.

The battery in the disclosure comprises a shell, and a battery core, a battery protection plate and the like which are wrapped in the shell. The battery protection board is an integrated circuit board which plays a role in protecting the battery core. The battery protection board is generally provided with a sampling circuit and a protection circuit. The battery may include a single cell or multiple cells. When the battery comprises a plurality of battery cells, the plurality of battery cells can be connected in series. Therefore, the charging voltage which can be borne by the battery is the sum of the charging voltages which can be borne by the plurality of battery cores, the charging speed can be increased, and the charging heat emission is reduced.

For example, taking the electronic device 10 as a mobile phone as an example, when the battery of the electronic device 10 includes a single cell, the voltage of the internal single cell is generally between 3.0V and 4.35V. And when the battery of the electronic device 10 includes two cells connected in series, the total voltage of the two cells connected in series is 6.0V to 8.7V. Therefore, compared with a single battery cell, when multiple battery cells are connected in series, the output voltage of the charging circuit can be improved. Compared with a single battery cell, the charging speed is equivalent, and the charging current required by multiple battery cells is about 1/N of the charging current required by a single battery cell (N is the number of the battery cells connected in series in the electronic device 10). In other words, on the premise of ensuring the same charging speed (the same charging current), the scheme of multiple cell segments can reduce the magnitude of the charging current, thereby reducing the heat productivity of the electronic device 10 during the charging process. On the other hand, compared with the single-cell scheme, the charging voltage can be increased by adopting the multi-cell series scheme under the condition that the charging current is kept the same, so that the charging speed is increased.

The present disclosure provides a charging control method that can improve the safety of an electronic device 10 in a working state while being charged. Fig. 2 shows a flowchart of an embodiment of the charging control method of the present disclosure. In this embodiment, the charge control method includes:

step S20, acquiring a work scene of the electronic device 10 and a position condition of the electronic device 10 relative to the target object;

the operating scenario can affect the heating or heat dissipation of the electronic device 10. The working scene of the electronic device 10 can be roughly divided into a working content scene and a working environment scene. The work content scenario may include an Application (APP) running on the electronic device 10, which may be an APP running in the foreground of the electronic device 10 only, or may include both APPs running in the background and foreground. The applications retrieved to be running on the electronic device 10 may be telephony-type applications, video-type applications, game-type applications, and the like. These applications may generate more heat during operation.

The application running on the electronic device 10 is typically triggered by a user, but may also be triggered by the system of the electronic device 10, for example, when the system needs to be upgraded, an upgrade application or program is started to upgrade the system. The electronic device 10 itself can detect the type and number of applications currently running.

The operating environment scenario may refer to a temperature condition of an operating environment of the electronic device 10. For example, when the electronic device 10 is operated in a relatively low temperature environment, thereby enabling faster heat dissipation, and when the electronic device 10 is operated in a relatively high temperature environment, the heat dissipation is slower.

In this embodiment, the target object may refer to a user and any other objects that may be used by the electronic device 10. The position of the electronic device 10 relative to the target object may be understood as a position state of the user when using the electronic device 10, for example, the user holds the electronic device 10 to wear the electronic device 10, the electronic device 10 is very close to the user but not in contact with the user (at a distance that the user can touch at will, the heat emitted by the electronic device 10 may have a certain effect on the user), the electronic device 10 is far away from the user (the heat emitted by the electronic device 10 hardly affects the user), and so on. It can be understood that, the influence degree of the heat generated by the electronic device 10 on the user is different according to the position of the electronic device 10 relative to the target object, and therefore, the adjustment amplitude is also different when the charging current is subsequently adjusted. Further, the above-mentioned position situation can be detected by a position sensor, an infrared sensor, or the like provided on the electronic apparatus 10.

During the whole charging process, the working scene of the electronic device 10 and the position condition of the electronic device 10 relative to the target object may change at any time, so that the working scene of the electronic device 10 and the position condition of the electronic device 10 relative to the target object may be obtained at regular intervals.

Step S21, acquiring a heat generation degree of the electronic device 10;

the degree of heat generation of the electronic device 10 may be embodied in various ways, such as the temperature inside the electronic device 10 (including the temperature of the internal motherboard or the temperature of the battery), the temperature rise of the electronic device 10 (including the temperature of the internal motherboard or the temperature of the battery), and the amount of radiation of the electronic device 10 radiated to the outside.

Here, the following two specific examples are proposed. The first embodiment is to determine the degree of heat generation from the temperature of the electronic apparatus 10; specifically, the method comprises the following steps:

the charging current regulation condition comprises a temperature threshold value which is greater than or equal to a preset temperature threshold value;

acquiring the degree of heat generation of the electronic apparatus 10 includes:

acquiring the current temperature of the electronic equipment 10;

when the heating degree of the electronic device 10 satisfies the charging current adjustment condition, adjusting the charging current of the electronic device 10 according to the working scene of the electronic device 10 and the position condition of the electronic device 10 relative to the target object includes:

when the current temperature of the electronic device 10 is greater than or equal to the preset temperature threshold, the charging current of the electronic device 10 is adjusted according to the working scene of the electronic device 10 and the position condition of the electronic device 10 relative to the target object.

In the second embodiment, the degree of heat generation is determined based on the rate of temperature rise of the electronic apparatus 10; specifically, the method comprises the following steps:

the charging current regulation condition comprises a temperature rise rate greater than or equal to a preset temperature rise rate;

acquiring the current temperature rise rate of the electronic equipment 10;

when the current temperature rise rate of the electronic device 10 is greater than or equal to the preset temperature rise rate, the charging current of the electronic device 10 is adjusted according to the working scene of the electronic device 10 and the position condition of the electronic device 10 relative to the target object.

In the present embodiment, the temperature increase rate is a temperature increase value of the electronic apparatus 10 per unit time.

In another embodiment, the degree of heat generation of the electronic device 10 may also be determined directly from whether the temperature rise is greater than or equal to a preset temperature.

In step S22, when the heat generation level of the electronic device 10 satisfies the charging current adjustment condition, the charging current of the electronic device 10 is adjusted according to the operation scene of the electronic device 10 and the position of the electronic device 10 relative to the target object.

In this embodiment, the charging current of the electronic device 10 is determined by combining the working scenario of the electronic device 10 and the position of the electronic device 10 relative to the target object after the heat generation degree of the electronic device 10 reaches a certain condition. Specifically, referring to fig. 3, fig. 3 is a flowchart illustrating an embodiment of adjusting the charging current of the electronic device 10 in step S22 in fig. 2. Referring to fig. 3, specifically, the adjusting the charging current of the electronic device 10 includes:

step S221, acquiring a charging mode of the electronic device 10;

the charging current of the electronic device 10 is adjusted according to the charging mode and the temperature difference between the current temperature of the electronic device 10 and the preset temperature threshold.

The charging mode of the electronic device 10 is a normal charging mode, i.e. the adapter outputs electric energy with a fixed charging parameter, for example, 5V, 2A. And the electronic device 10 adjusts the current charged in the battery through its own charge control chip. In addition, the charging mode of the electronic device 10 includes a PD charging mode, a QC charging mode, a VOOC charging mode, a segment constant current charging mode, and the like. The following two embodiments are proposed in the present disclosure according to different types of charging modes.

In one embodiment, the charging mode comprises a first charging mode;

adjusting the charging current according to the charging mode and the temperature difference between the current temperature of the electronic device 10 and the preset temperature threshold includes:

step S222a, when the charging mode is the first charging mode, determining a first charging current adjustment value corresponding to a temperature difference between a current temperature of the electronic device 10 and a preset temperature threshold according to a corresponding relationship between a preset temperature difference and a charging current adjustment value;

in step S223a, the electronic device 10 is charged by the difference between the current charging current and the first charging current adjustment value.

The first charging mode may be a normal charging mode. In the normal charging mode, the electronic device 10 can flexibly adjust the specific value of the charging current.

There may be various corresponding relationships between the preset temperature difference and the charging current adjustment value. For example, the temperature difference is linearly related to the adjustment value of the charging current. I.e. a temperature difference of 1 deg.c, the corresponding charging current adjustment value is-500 mA, i.e. the current temperature of the electronic device 10 is 26 deg.c, the preset temperature threshold is 25 deg.c, the temperature difference is 1 deg.c, the charging current is adjusted down by 500mA, the current temperature of the electronic device 10 is 27 deg.c, the temperature difference is 2 deg.c, and the charging current is adjusted down by 1000 mA. The larger the temperature difference, the larger the total adjustment of the charging current. However, it should be noted that the charging current is always higher than the preset minimum charging current threshold value to ensure that the charging can be performed normally.

In another example, the preset temperature difference and the charging current adjustment value may have a non-linear correspondence relationship. For example, the charging current is adjusted to 500mA at a temperature difference of 1 deg.C, and 1200mA at a temperature difference of 2 deg.C. Therefore, when the temperature of the electronic device 10 is high, the charging current is adjusted downward by a large margin, so as to reduce the heat generated by the electronic device 10.

In another embodiment, corresponding to some charging modes, the charging parameters are divided into a plurality of fixed gears, for example, when the PD is charged, the charging parameters are 5V/3A, 5V/2A, 5V/1A, etc. Therefore, when the charging current needs to be reduced, only a certain fixed charging parameter gear can be adjusted downwards.

Specifically, the charging mode includes a second charging mode; the second charging mode has a plurality of charging parameter gears;

in step S222b, when the charging mode is the second charging mode, a first charging parameter gear corresponding to the temperature difference between the current temperature of the electronic device 10 and the preset temperature threshold is determined according to the corresponding relationship between the preset temperature difference and the charging parameter gear.

In step S223b, the electronic device 10 is charged by adjusting the current charging parameter unit to the first charging parameter unit.

The second charging mode may be a PD charging mode, a QC charging mode, or a VOOC charging mode. For example, the current charging parameter is 5V/3A, and when the charging current needs to be adjusted downwards, the first charging parameter gear can be 5V/2A or 5V/1A.

When the corresponding relationship between the preset temperature difference and the charging parameter gear is set, it is first determined which charging parameter gears are supported by the electronic device 10 and the adapter, and when the temperature difference is larger, the charging parameter gear with smaller charging power can be selected. In a specific embodiment, the charging parameter may be adjusted one step down for every 2 ℃ increase in temperature difference.

A portion of the drive control logic of the present disclosure is described below. The working scene of the electronic device 10 and the heating degree of the mobile phone can be obtained through the upper application program logic. And a node is set in the memory through software, the node can be 32bit data, and an agreement is achieved with an upper application program. Setting bits 0-12 as VOOC mode; bit 12-bit 16 other quick charging modes; bits 17-32 are used in the normal charging mode. Wherein each byte (bit) can be set to represent a gear.

After acquiring the working scene of the electronic device 10 and the heating degree of the mobile phone, the upper layer application program logic converts the working scene into a corresponding digital signal. After receiving the data given by the upper layer, the node can judge the current charging mode, and set the corresponding charging current according to the charging mode, so as to achieve the purposes of reducing the charging current and reducing the temperature of the charging equipment.

In order to ensure the safety of using the electronic device 10 by the user during charging and ensure the charging speed, in the following embodiment, in the case where the degree of heat generation of the electronic device 10 satisfies the charging current adjustment condition, the magnitude of the charging current adjustment is described separately for different situations according to the operating scenario of the electronic device 10 and the position of the electronic device 10 relative to the target object. The position of the electronic device 10 relative to the target object is described by taking the example of whether the electronic device 10 is held by a hand or not. Referring to fig. 4, fig. 4 is a flowchart illustrating an embodiment of step S22 in fig. 2.

Referring to fig. 3, in an embodiment, a manner of adjusting the charging current of the electronic device 10 includes a first adjustment mode;

according to the working scene of the electronic device 10 and the handheld condition of the electronic device 10, adjusting the charging current of the electronic device 10 includes:

step S224, comparing the working scene of the electronic device 10 with a preset working scene;

in step S225a, when the working scenario of the electronic device 10 matches the preset working scenario and the electronic device 10 is not held by hand, the charging current of the electronic device 10 is adjusted in the first adjustment mode.

There are many setting principles regarding the preset working scenario, and in one embodiment, the preset working scenario is set according to the number of users of the application program of the electronic device 10. For example, when the usage awareness of an application reaches 1 hundred million, the application is set as a preset work scene.

In another embodiment, the preset operating scenario is set according to the operating power of the application of the electronic device 10. The greater the operating power, the greater the heat generated during operation. Therefore, the video application program, the resource downloading application program and the call application program with larger running power can be preset as preset working scenes.

Of course, the preset working scene can be set by the manufacturer and the user. For example, when a user uses a certain application program, the user perceives that the heating amount is large, so that the application program can be set as a preset working scene in a setting window of the mobile phone, and thus, in the charging process, when the application program is operated, the charging current can be adjusted to control the heating amount of the electronic device 10.

In the present embodiment, corresponding to the classification of the working scenario of the electronic device 10 mentioned in the above embodiments, the preset working scenario also has a corresponding classification. When the work scene of the electronic device 10 is the work content scene, the preset work scene is also the preset work content scene correspondingly.

In an example, the preset work content scene may be a preset application classification. Such as a telephony-like application, a video-like application, a game-like application, etc. And if the currently running application program is the 'Tencent video' APP, matching with the video application program occurs.

In one example, the preset work content scene may be a specific preset application program. For example, the specific application programs such as "Tengchi video", "Wangzheng glory", "WeChat" and the like. And if the currently running application program is 'royal glory' APP, matching with the preset 'royal glory' APP.

When the working scene of the electronic device 10 is the working environment scene, the preset working scene is also the preset working environment scene correspondingly.

In an example, the preset work content scene is an ambient temperature, which may be a threshold value, for example, greater than 35 ℃, and when the ambient temperature at which the electronic device 10 works is obtained to be 36 ℃, the work scene of the electronic device 10 matches the preset work scene.

In the embodiment, when the working scene of the electronic device 10 matches the preset working scene, it is described that the operation of the electronic device 10 will continuously generate more heat, and therefore, the charging current needs to be reduced to reduce the heat generated by charging. However, since the electronic device 10 is not held by hand, even if the temperature of the electronic device 10 is high, the user is not affected, and therefore, the charging current does not need to be greatly reduced to ensure the charging speed.

For example, the user watches the video played by the "flight news video" APP on the mobile phone through the mobile phone support, and because the user does not hold the mobile phone, the mobile phone generates heat and has little influence on the user, and when the heating degree of the electronic device 10 meets the charging current regulation condition, on the premise of ensuring charging safety, the charging current can be reduced less.

In another embodiment, in step S225b, when the working scenario of the electronic device 10 does not match the preset working scenario and the electronic device 10 is held in hand, the charging current of the electronic device 10 is adjusted in the second adjustment mode.

In the embodiment, when the working scene of the electronic device 10 is not matched with the preset working scene, it indicates that the working of the electronic device 10 does not generate much heat, so that the charging current does not need to be greatly reduced. However, since the electronic device 10 is held by hand, the temperature of the electronic device 10 needs to be controlled not to be too high, and therefore, the charging current needs to be reduced appropriately to ensure the use safety and the use experience of the user.

For example, the user holds the mobile phone, uses "mei bao" APP, because the user holds the mobile phone, but because "mei bao" APP operating power is not big, consequently can not produce more heat, when the degree of generating heat of electronic device 10 satisfies charging current regulation condition, under the prerequisite of guaranteeing charging safety, reduction charging current that can be less.

in step S225c, when the working scenario of the electronic device 10 matches the preset working scenario and the electronic device 10 is held by hand, the charging current of the electronic device 10 is adjusted in the third adjustment mode.

In this embodiment, when the working scene of the electronic device 10 matches the preset working scene, it is described that the operation of the electronic device 10 will continuously generate more heat, and therefore, the charging current needs to be reduced to reduce the heat generated by charging. Moreover, since the electronic device 10 is held by hand, the temperature of the electronic device 10 needs to be controlled not to be too high, and therefore, the charging current needs to be reduced more, so as to ensure the use safety and the use experience of the user.

For example, when a user watches a video played by "flight news video" APP on a mobile phone through a handheld mobile phone, since the user holds the mobile phone, the heat generation of the mobile phone has an influence on the user, and the operating power of the "flight news video" APP is higher, so that when the heat generation degree of the electronic device 10 meets the charging current adjustment condition, the charging current needs to be reduced to a greater degree.

Therefore, in the present embodiment, a charging current down-regulation amount corresponding to the third adjustment mode is greater than a charging current down-regulation amount corresponding to the first adjustment mode, and a charging current down-regulation amount corresponding to the third adjustment mode is greater than a charging current down-regulation amount corresponding to the second adjustment mode, corresponding to a temperature difference between the current temperature of the electronic device 10 and the preset temperature threshold.

When the current temperature of the electronic device 10 is 26 ℃ and the temperature threshold is 25 ℃, the temperature difference is 1 ℃. The charging current down-regulation amount corresponding to the first regulation mode is 500mA, the charging current down-regulation amount corresponding to the second regulation mode is also 500mA, and the charging current down-regulation amount corresponding to the third regulation mode is 800 mA.

It should be noted that the first regulation mode, the second regulation mode, and the third regulation mode may be two embodiments of regulating the charging current in the above embodiments.
