Description

Technical Field

The present disclosure relates to the field of electronic devices, and in particular, to a charging control method, apparatus, device, and readable storage medium.

Background

Electronic devices (e.g., smart devices such as smart phones and tablet computers) are becoming more popular with consumers, but these electronic devices consume a large amount of power and require frequent charging. To meet the challenge of charging these devices to be charged by using a low-power ordinary charging scheme, several high-power fast charging schemes are proposed in the industry on the basis of ordinary charging, including a high-voltage-based fast charging scheme and a high-current-based fast charging scheme.

However, no matter the rapid charging scheme based on the large voltage or the rapid charging scheme based on the large current, because the power of the electric energy provided during charging is large, the temperature of the electronic device inevitably rises rapidly, and particularly, when the electronic device runs an application with large power consumption at the same time, the temperature of the electronic device rises remarkably, which is not beneficial to the improvement of the charging efficiency, and also leads to poor user experience. In addition, the temperature of the electronic device during charging may exceed relevant standards (e.g., national standard, enterprise standard, etc.).

How to provide an intelligent charging control method for electronic equipment based on the application scene of the electronic equipment in the charging process becomes a problem to be solved urgently.

Hereinafter, each step of the charging method provided by the exemplary embodiment of the present disclosure will be described in more detail with reference to the drawings and examples.

Fig. 1 exemplarily shows a flowchart of a charging control method in an embodiment of the present disclosure. The method provided by the embodiment of the disclosure can be applied to any equipment to be charged.

The device to be charged may be, for example, a terminal or an electronic device including, but not limited to, a device configured to receive/transmit communication signals via a wireline connection, such as via a Public Switched Telephone Network (PSTN), a Digital Subscriber Line (DSL), a digital cable, a direct cable connection, and/or another data connection/network and/or via a Wireless Local Area Network (WLAN), a digital television network such as a digital video broadcasting-handheld (DVB-H) network, a satellite network, an amplitude modulation-frequency modulation (AM-FM) broadcast transmitter, and/or a wireless interface of another terminal, for example. Communication terminals arranged to communicate over a wireless interface may be referred to as "wireless communication terminals", "wireless terminals", and/or "mobile terminals". Examples of terminals include, but are not limited to, satellite or cellular telephones; personal Communication System (PCS) terminals that may combine a cellular radiotelephone with data processing, facsimile and data communication capabilities; personal Digital Assistants (PDAs) that may include radiotelephones, pagers, internet/intranet access, Web browsers, notepads, calendars, and/or Global Positioning System (GPS) receivers; and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver. In addition, the terminal may further include, but is not limited to, a rechargeable electronic device having a charging function, such as an electronic book reader, a smart wearable device, a mobile power source (e.g., a charger, a travel charger), an electronic cigarette, a wireless mouse, a wireless keyboard, a wireless headset, a bluetooth speaker, and the like.

Referring to fig. 1, a charge control method 10 includes:

in step S102, a type of an application currently running in the device to be charged is detected, and an application level corresponding to the type of the application is determined.

When the device to be charged is charged, if other applications are running, the temperature of the device to be charged is affected. But the extent of the temperature rise caused varies for different types of applications. Such as telephony, video, etc., types of applications, the temperature rise is low compared to large, networked game-type applications.

Various types of applications that may be running in the device to be charged may be classified into different classes depending on their power consumption (or the extent to which they induce a temperature rise in the device to be charged). Each class of application corresponds to a different charging current. As mentioned above, for example, a large networked game class or the like type of application may be categorized into one level, such as a first level; applications of the call class, video class, etc. type are assigned to one level, such as the second level. The power consumption of the first-level application is higher than that of the second-level application, and the charging current corresponding to the first-level application is lower than that of the second-level application. The above-mentioned division of the levels for different types of applications is only an example, not limiting the present disclosure, and in actual applications, the preset application levels may be configured according to actual requirements. The temperature rise is controlled according to the application level, so that the temperature of the electronic equipment can be controlled in a self-adaptive manner when the equipment to be charged runs different applications while charging, and the problem of equipment heating of the equipment to be charged caused by the temperature rise and the danger caused by overheating of the equipment to be charged are avoided.

Without loss of generality, taking an operating system running in the device to be charged as an android operating system as an example, at the beginning of charging or during charging, the type of an application currently running in the device to be charged may be detected by an upper layer (such as an application layer or an application framework layer) of the android operating system. And searching the application grade corresponding to the application of the type in the corresponding relation between the application type and the application grade stored in advance.

In addition, the user may switch different application types during the charging process, and the detection of the application types may be performed periodically.

In step S104, based on the application level, a first charging current corresponding to the application level is determined.

As described above, different charging currents may be preset for different application levels. As described above, the charging current corresponding to the application belonging to the first class is set to 4A, and the charging current corresponding to the application belonging to the second class is set to 5A, and it should be noted that these charging current values are merely examples and do not limit the present disclosure.

For example, the charging current value corresponding to each application level may be stored in advance, and after the application level to which the currently running application belongs is determined, the corresponding first charging current may be queried.

In step S106, temperature information of the device to be charged is acquired, and a second charging current corresponding to the temperature information is determined.

The temperature information of the device to be charged may be, for example, a detected temperature of the battery, or a detected temperature of a housing of the device to be charged (e.g., a temperature of the back housing, or a maximum temperature of different preset portions of the back housing), and the like, and the disclosure is not limited thereto. In addition, the temperature information includes an initial temperature and also includes a current temperature detected in real time during the charging process.

As described above, the temperature of the device to be charged is directly affected by the magnitude of the charging current, and the magnitude of the charging current corresponding to the temperature is determined based on the current temperature of the device to be charged, so that the temperature rise of the device to be charged can be effectively controlled.

In step S108, a target charging current value of the device to be charged is determined based on the first charging current and the second charging current.

And simultaneously considering a first charging current corresponding to the application based on the current operation and a second charging current corresponding to the temperature of the current equipment to be charged, and determining the target charging current value of the equipment to be charged.

For example, the minimum value of the first charging current and the second charging current may be selected as the target charging current value.

In step S110, the charging current of the battery in the device to be charged is adjusted to a target charging current value.

According to the charging control method provided by the embodiment of the disclosure, in the charging process, when the target charging current value is determined, the target charging current value determined by referring to the first charging current corresponding to the currently running application and the second charging current corresponding to the temperature of the current device to be charged is also determined, and meanwhile, the application scene, the temperature rise condition and the charging speed are considered, so that the temperature rise can be effectively controlled while the charging speed is ensured, the charging efficiency is improved, and the user experience is improved.

Fig. 2 exemplarily shows a flowchart of another charging control method in the embodiment of the present disclosure. The difference from the charging control method 10 shown in fig. 1 is that the method shown in fig. 2 further provides an embodiment of how to obtain the temperature information of the device to be charged and determine the second charging current corresponding to the temperature information, that is, the method shown in fig. 2 is a further extension of step S106 in fig. 1.

Referring to fig. 2, step S106 includes:

in step S1062, the initial temperature of the battery and the current temperature of the battery are acquired, respectively.

The detection of the current temperature of the battery can be performed, for example, by a cycle-initiated thread, so that the charging current is adjusted on the basis of the battery temperature measured in real time.

In step S1064, the initial temperature of the battery is compared with a preset temperature threshold.

The temperature information is, for example, the temperature of the battery, and the initial temperature of the battery may be compared with a preset temperature threshold.

In step S1066, a second charging current corresponding to the present temperature of the battery is determined according to the comparison result.

Firstly, comparing the initial temperature of the battery with a preset temperature threshold, and determining different second charging currents according to the comparison result, namely determining a second charging current when the initial temperature of the battery is higher than the temperature threshold; and when the initial temperature of the battery is lower than the temperature threshold, another different second charging current is determined. Such an arrangement may better achieve a balance between re-reading speed and temperature rise.

In some embodiments, step S1066 may further include:

s1: and when the initial temperature of the battery is lower than the temperature threshold, determining the second charging current based on a preset first temperature current corresponding relation.

The first temperature correspondence may be stored in the device to be charged in advance, and is used to record a relationship between the temperature of the battery and the second charging current when the initial temperature of the battery is lower than the temperature threshold.

For example, the temperature threshold may be, for example, 32.5 degrees. When the temperature of the battery rises to 43 degrees, the charging current is reduced to 5A; when the temperature of the battery rises to 43.5 degrees, the charging current is reduced to 4A; when the temperature of the battery rises to 44 degrees, the charging current is reduced to 3A; when the temperature of the battery drops back to 42.5 degrees, the charging current rises back to 4A; when the temperature of the battery drops back to 42 degrees, the charging circuit rises back to 5A.

In some embodiments, the first temperature correspondence may also be implemented as a state machine. Fig. 3A exemplarily shows a state machine corresponding to the first temperature correspondence in the embodiment of the present disclosure. As shown in fig. 3A, when the initial temperature of the battery is less than the battery threshold, the second charging current corresponding to the initial state st1_ int is 6.5A, the second charging current corresponding to the first high temperature state st1_1 is 5A, the second charging current corresponding to the second high temperature state st1_2 is 4A, and the second charging current corresponding to the third high temperature state st1_3 is 3A.

S2: and when the initial temperature of the battery is higher than the temperature threshold value, determining the second charging current value based on a preset second temperature current corresponding relation.

The second temperature correspondence may be pre-stored in the device to be charged, and is used to record the relationship between the temperature of the battery and the second charging current when the initial temperature of the battery is higher than the temperature threshold.

For example, when the temperature of the battery rises to 38 degrees, the charging current decreases to 6A; when the temperature of the battery rises to 39.5 degrees, the charging current is reduced to 5A; when the temperature of the battery rises to 41.5 degrees, the charging current is reduced to 4A; when the temperature of the battery rises to 42 degrees, the charging current is reduced to 3A; when the temperature of the battery is reduced to 40.5 ℃, the charging current is increased back to 4A; when the temperature of the battery drops back to 38.5 degrees, the charging circuit rises back to 5A.

In some embodiments, the second temperature correspondence may also be implemented as a state machine. Fig. 3B exemplarily shows a state machine corresponding to the second temperature correspondence in the embodiment of the present disclosure. As shown in fig. 3B, when the initial temperature of the battery is greater than the battery threshold, the second charging current corresponding to the initial state st2_ int is 7.5A, the second charging current corresponding to the first high temperature state st2_1 is 6A, the second charging current corresponding to the second high temperature state st2_2 is 5A, the second charging current corresponding to the third high temperature state st2_3 is 4A, and the second charging current corresponding to the fourth high temperature state st2_4 is 3A.

It should be noted that, when the initial temperature of the battery is equal to the temperature threshold, the first temperature corresponding relationship may be executed, or the second temperature corresponding relationship may also be executed, and in practical applications, whether to execute the first temperature corresponding relationship or the second temperature corresponding relationship may be set according to actual requirements.

In addition, the above-described values of the respective parameters are merely illustrative and do not limit the present disclosure.

The charging control method provided by the embodiment of the disclosure further designs a mechanism for dynamically adjusting the charging current of the battery based on the temperature, and when the temperature of the battery rises, the charging current value is correspondingly reduced; the reduction of the charging current will reduce the temperature of the battery, and when the temperature of the battery falls back, the charging current value is increased accordingly. In addition, the mechanism also adds a measure for preventing jitter, for example, as mentioned above, when designing the temperature, the jitter prevention temperature of 1.5 degrees is set.

In addition, tests have found that charging a device to be charged based on this method, although it is somewhat reduced in terms of the time of use to fully charge the battery, is reduced by only a few minutes compared to the charging time without the above-described intelligent control (about 30 minutes). Therefore, the method simultaneously considers the charging speed and the temperature rise condition of the equipment to be charged.

Fig. 4 exemplarily shows a flowchart of still another charge control method in the embodiment of the present disclosure. Unlike the charging control method 10 shown in fig. 1, in order to avoid the problem that the charging current value determined this time is higher than the charging current value determined last time when the battery voltage is large, the charging control method 20 shown in fig. 4 further includes, before step S110:

in step S202, the voltage of the battery is detected.

The present voltage of the battery can be detected, for example, by a detection module in the device to be charged.

In step S204, when the voltage of the battery is higher than the preset voltage threshold, a charging current value determined and adjusted last time is obtained, and a minimum value between the charging current value determined and adjusted last time and the determined target charging current value is selected as the target charging current value of this time.

By the method, the finally determined charging current value to be adjusted is set to be the smaller value of the charging current value determined and adjusted at the previous time and the charging current value determined at this time to be adjusted, so that the problem that the charging current value determined at this time is higher than the charging current value determined at the previous time under the condition of more battery voltage can be avoided.

Fig. 5 exemplarily shows a flowchart of still another charge control method in the embodiment of the present disclosure. Unlike the charging control methods described above, the charging control method shown in fig. 5 further provides an example of how to adjust the charging current of the battery in the device to be charged to the target charging current value, that is, the method shown in fig. 5 is a further extension of step S110 in fig. 1.

Those skilled in the art will appreciate that all or part of the steps for implementing the above embodiments are implemented as computer programs executed by a CPU or Application Processor (AP) of the device to be charged. When the computer program is executed by the CPU or the AP, the above-described functions defined by the above-described methods provided by the present disclosure are performed. Alternatively, all or part of the steps of the above embodiments may also be implemented as executable code executed by a Micro Controller Unit (MCU) in the device to be charged. When executed, performs the functions defined by the method.

When the device to be charged includes both the AP and the control module implemented as the MCU, step S110 may include:

in step S1102, the target charging current value is sent to the control module in the device to be charged, so that the charging current of the battery in the device to be charged is adjusted to the target charging current value by the control module.

The control module may be implemented as the MCU described above, for example, to control the charging process of the device to be charged.

After receiving the charging current value, the control module may notify the power supply device to adjust the output current to the charging current value.

The control module can communicate with the power supply device through a charging interface of the equipment to be charged. If the charging interface is a USB interface, the control module and the power supply device may communicate based on a data line (e.g., a D + line and/or a D-line) in the USB interface. If the charging interface is a USB interface (e.g., a USB TYPE-C interface) supporting a PD communication protocol, the control module and the power supply device may communicate based on the PD communication protocol.

By communicating with the power supply device, the power supply device is informed to adjust the charging current to the charging current value matched with the type and application level of the power supply device.

Or, the control module may also control the voltage conversion module in the device to be charged to adjust the charging current of the battery to the charging current value.

The device to be charged can be provided with a voltage conversion module, and the voltage conversion module can convert the voltage and/or current output by the power supply device under the control of the control module so as to adjust the charging current of the battery to the charging current value matched with the type and application level of the power supply device.

In some embodiments, the target charging current value may be sent to a control module in the device to be charged, such as by a predefined field; wherein the field contains a predefined number of bits, with different assignments for representing different target charge current values. Taking a 4-bit field as an example, 0x6 may indicate that the target charging current value is 6A, 0x5 may indicate that the target charging current value is 5A, 0x4 may indicate that the target charging current value is 4A, 0x3 may indicate that the target charging current value is 3A, and so on. Through the predefined field, various values of the charging current to be adjusted can be indicated for the control module.

Referring to fig. 6, the charge control method 30 includes:

in step S302, the type of the power supply apparatus connected to the device to be charged is acquired.

For example, the type of the power supply apparatus may be acquired by communicating with the power supply apparatus.

In step S304, it is determined whether the type of the power supply device supports jointly adjusting the current based on the application level and the temperature.

If the type of the power supply device does not support the joint adjustment of the current based on the application level and the temperature, step S316 is entered.

If the type of the power supply device supports jointly adjusting the current based on the application level and the temperature, the process proceeds to step S306.

In some embodiments, the determination of step S304 is only performed after confirming that the type of the power supply device supports fast charging, i.e. the above-mentioned mechanism for jointly adjusting the charging current based on the application level and the temperature is only performed in the fast charging mode.

The following describes a "normal charge mode" and a "fast charge mode" in the charging system.

The normal charging mode refers to a power supply device (such as an adapter) outputting a relatively small current value (typically less than 2.5A) or charging a battery in a device to be charged with relatively small power (typically less than 15W). It usually takes several hours to fully charge a larger capacity battery (e.g., 3000 ma-hour capacity battery) in the normal charging mode.

The fast charging mode means that the power supply device can output a relatively large current (typically greater than 2.5A, such as 4.5A, 5A or even higher) or charge a battery in the charging device with a relatively large power (typically greater than or equal to 15W).

Compared with the ordinary charging mode, the charging speed of the power supply device in the fast charging mode is faster, and the charging time required for completely charging the battery with the same capacity can be obviously shortened.

The power supply device can be a common adapter, for example, a power adapter with maximum output power of 10W (5V/2A) and which charges the device to be charged by adopting the common charging mode; alternatively, the power supply device may be a fast charging adapter, for example, a high-power adapter with a maximum output power of 50W (10V/5A), and the above fast charging mode is adopted to charge the device to be charged; still alternatively, the power supply device may also be another fast charging adapter, for example, a 20W (5V/4A) high-power adapter, and the above fast charging mode is adopted to charge the device to be charged.

In step S306, the type of the application currently running in the device to be charged is detected, and the application level corresponding to the application of the type is determined.

In step S308, based on the application level, a first charging current corresponding to the application level is determined.

In step S310, temperature information of the device to be charged is acquired, and a second charging current corresponding to the temperature information is determined.

In step S312, a target charging current value of the device to be charged is determined based on the first charging current and the second charging current.

In step S314, the charging current of the battery in the device to be charged is adjusted to the target charging current value.

In step S316, the charging current of the battery in the device to be charged is adjusted to the preconfigured charging current value.

The preconfigured charging current value may be, for example, a charging current value that matches the type of power supply device.

Furthermore, it should be noted that the above-mentioned figures are only schematic illustrations of the processes involved in the methods according to exemplary embodiments of the present disclosure, and are not intended to be limiting. It will be readily understood that the processes shown in the above figures are not intended to indicate or limit the chronological order of the processes. In addition, it is also readily understood that these processes may be performed synchronously or asynchronously, e.g., in multiple modules.
