Description

Background Art

[0002] Electronic devices (such as smart phones, tablets and other smart devices) are becoming more and more popular among consumers, but these electronic devices consume a lot of power and need to be charged frequently. It usually takes several hours to charge these devices using low-power ordinary charging solutions. In order to meet this challenge, the industry has successively proposed a variety of high-power fast charging solutions based on ordinary charging, including fast charging solutions based on high voltage and fast charging solutions based on high current.

[0003] However, whether it is a fast charging solution based on high voltage or high current, the temperature of the electronic device will inevitably rise rapidly due to the high power of the electric energy provided during charging, especially when running high-power applications in the electronic device at the same time, the temperature rise of the electronic device is particularly significant, which is not conducive to improving the charging efficiency and also leads to poor user experience. In addition, the temperature of the electronic device during charging may exceed the relevant standards (such as national standards, enterprise standards, etc.).

[0004] How to provide an intelligent charging control method for electronic devices based on the application scenarios of the electronic devices during the charging process has become an urgent problem to be solved.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0026] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and their repeated description will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0027] 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 accompanying drawings and embodiments.

[0028] Figure 1 The flowchart of a charging control method in the embodiment of the present disclosure is exemplarily shown. The method provided in the embodiment of the present disclosure can be applied to any device to be charged.

[0029] The device to be charged may be, for example, a terminal or electronic device, including but not limited to a device configured to receive / send communication signals via a wired line 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, for example, a cellular network, 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. A communication terminal configured to communicate via a wireless interface may be referred to as a "wireless communication terminal", "wireless terminal" and / or "mobile terminal". Examples of terminals include, but are not limited to, satellite or cellular telephones; personal communication system (PCS) terminals that can combine cellular radio telephones with data processing, fax and data communication capabilities; personal digital assistants (PDAs) that can include radio telephones, pagers, Internet / intranet access, web browsers, notepads, calendars and / or global positioning system (GPS) receivers; and conventional laptop and / or handheld receivers or other electronic devices including radio telephone transceivers. In addition, the terminal may also include, but is not limited to, rechargeable electronic devices with charging functions such as e-book readers, smart wearable devices, mobile power supplies (such as power banks, travel chargers), electronic cigarettes, wireless mice, wireless keyboards, wireless headphones, Bluetooth speakers, etc.

[0030] refer to Figure 1 , the charging control method 10 comprises:

[0031] In step S102, the type of application currently running in the device to be charged is detected, and the application level corresponding to the application of this type is determined.

[0032] If other applications are running while the device is charging, the temperature of the device will be affected. However, different types of applications will cause different degrees of temperature rise. For example, the temperature rise of applications such as calls and videos is lower than that of large-scale online game applications.

[0033] The various types of applications that may be run in the device to be charged can be divided into different levels according to their power consumption (or the degree to which the temperature of the device to be charged rises). Each level of application corresponds to a different charging current. As mentioned above, for example, applications such as large-scale online games can be classified into one level, such as the first level; and applications such as call and video can be classified into one level, such as the second level. Among them, 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 the charging current value corresponding to the second-level application. The above-mentioned classification of the levels of different types of applications is only an example, not a limitation of the present disclosure. In actual application, the preset application level can be configured according to actual needs. Controlling the temperature rise according to the application level can enable the device to be charged to adaptively control the temperature of the electronic device when running different applications while charging, so as to avoid the problem of heating of the device to be charged due to the temperature rise, and the danger caused by overheating of the device to be charged.

[0034] Without loss of generality, taking the Android operating system as an example, when charging starts or during charging, the upper layer of the Android operating system (such as the application layer or the application framework layer) can detect the type of application currently running in the device to be charged, and search for the application level corresponding to the type of application in the pre-stored correspondence between the application type and the application level.

[0035] In addition, the user may switch between different application types during the charging process, and the above detection of the application type may be performed periodically.

[0036] In step S104 , based on the application level, a first charging current corresponding to the application level is determined.

[0037] As described above, different charging currents may be preset for different application levels. For example, the charging current corresponding to the first level application is set to 4A, and the charging current corresponding to the second level application is set to 5A. It should be noted that these charging current values ​​are only examples and do not limit the present disclosure.

[0038] For example, the charging current values ​​corresponding to the application levels may be pre-stored, and after determining the application level to which the currently running application belongs, the corresponding first charging current may be queried.

[0039] In step S106, the temperature information of the device to be charged is obtained, and a second charging current corresponding to the temperature information is determined.

[0040] The temperature information of the device to be charged may be, for example, the detected temperature of the battery, or the detected temperature of the shell of the device to be charged (such as the temperature of the back shell, or the highest temperature of different preset parts of the back shell), etc., but the present disclosure is not limited thereto. In addition, the temperature information includes the initial temperature and the current temperature detected in real time during the charging process.

[0041] As mentioned above, the magnitude of the charging current will directly affect the temperature of the device to be charged. Based on the current temperature of the device to be charged, the magnitude of the charging current corresponding to the temperature is determined, which can effectively control the temperature rise of the device to be charged.

[0042] 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.

[0043] A target charging current value of the device to be charged is determined by simultaneously considering a first charging current corresponding to a currently running application and a second charging current corresponding to a current temperature of the device to be charged.

[0044] For example, the minimum value between the first charging current and the second charging current may be selected as the target charging current value.

[0045] In step S110, the charging current of the battery in the device to be charged is adjusted to a target charging current value.

[0046] The charging control method provided by the embodiment of the present disclosure, during the charging process, refers to the target charging current value determined by a first charging current corresponding to the currently running application and a second charging current corresponding to the current temperature of the device to be charged, while taking into account the application scenario, temperature rise and charging speed. It can effectively control the temperature rise while ensuring the charging speed, thereby improving the charging efficiency and enhancing the user experience.

[0047] Figure 2 The flowchart of another charging control method in the embodiment of the present disclosure is exemplarily shown. Figure 1 The difference of the charging control method 10 shown is that Figure 2 The method shown 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, Figure 2The method shown is Figure 1 A further extension of step S106.

[0048] refer to Figure 2 , step S106 includes:

[0049] In step S1062 , the initial temperature of the battery and the current temperature of the battery are respectively acquired.

[0050] The current temperature of the battery may be detected, for example, by a periodically started thread, thereby adjusting the charging current based on the real-time measured battery temperature.

[0051] In step S1064 , the initial temperature of the battery is compared with a preset temperature threshold.

[0052] Taking the temperature of a battery as an example, the temperature information may firstly be compared with a preset temperature threshold.

[0053] In step S1066, a second charging current corresponding to the current temperature of the battery is determined according to the comparison result.

[0054] First, the initial battery temperature is compared with a preset temperature threshold, and different second charging currents are determined according to the comparison result, that is, when the initial battery temperature is higher than the temperature threshold, a second charging current is determined; and when the initial battery temperature is lower than the temperature threshold, another different second charging current is determined. Such a setting can better achieve a balance between re-reading speed and temperature rise.

[0055] In some embodiments, step S1066 may further include:

[0056] S1: When the initial battery temperature is lower than the temperature threshold, the second charging current is determined based on a preset first temperature-current correspondence relationship.

[0057] The first temperature correspondence relationship may be pre-stored in the device to be charged, and is used to record the relationship between the battery temperature and the second charging current when the initial battery temperature is lower than the temperature threshold.

[0058] For example, the temperature threshold may be 32.5 degrees. When the battery temperature rises to 43 degrees, the charging current is reduced to 5A; when the battery temperature rises to 43.5 degrees, the charging current is reduced to 4A; when the battery temperature rises to 44 degrees, the charging current is reduced to 3A; when the battery temperature drops back to 42.5 degrees, the charging current is increased to 4A; when the battery temperature drops back to 42 degrees, the charging current is increased to 5A.

[0059] In some embodiments, the first temperature correspondence may also be implemented as a state machine. Figure 3AThe state machine corresponding to the first temperature correspondence in the embodiment of the present disclosure is exemplarily shown. Figure 3A As shown, when the initial battery temperature 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.

[0060] S2: When the initial battery temperature is higher than the temperature threshold, the second charging current value is determined based on a preset second temperature-current correspondence relationship.

[0061] The second temperature correspondence relationship may be pre-stored in the device to be charged, and is used to record the relationship between the battery temperature and the second charging current when the initial battery temperature is higher than the temperature threshold.

[0062] For example, when the battery temperature rises to 38 degrees, the charging current is reduced to 6A; when the battery temperature rises to 39.5 degrees, the charging current is reduced to 5A; when the battery temperature rises to 41.5 degrees, the charging current is reduced to 4A; when the battery temperature rises to 42 degrees, the charging current is reduced to 3A; when the battery temperature drops back to 40.5 degrees, the charging current returns to 4A; when the battery temperature drops back to 38.5 degrees, the charging current returns to 5A.

[0063] In some embodiments, the second temperature correspondence may also be implemented as a state machine. Figure 3B The state machine corresponding to the second temperature correspondence in the embodiment of the present disclosure is exemplarily shown. Figure 3B As shown, when the initial battery temperature 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.

[0064] It should be noted that when the initial battery temperature is equal to the temperature threshold, the first temperature correspondence may be executed, or the second temperature correspondence may be executed. In practical applications, whether to execute the first temperature correspondence or the second temperature correspondence may be set according to actual needs.

[0065] In addition, the above parameter values ​​are only for illustration and are not intended to limit the present disclosure.

[0066] The charging control method provided in the embodiment of the present disclosure further designs a mechanism for dynamically adjusting the battery charging current based on temperature. When the battery temperature rises, the charging current value is reduced accordingly; and the reduction of the charging current will cause the battery temperature to drop. When the battery temperature drops back, the charging current value is increased accordingly. In addition, anti-shake measures are added to the mechanism. For example, as mentioned above, an anti-shake temperature of 1.5 degrees is set when designing the temperature.

[0067] In addition, through testing, it was found that the time required to fully charge the battery of the device to be charged based on this method was reduced, but it was only reduced by a few minutes compared to the charging time without the above intelligent control (about 30 minutes). Therefore, this method takes into account both the charging speed and the temperature rise of the device to be charged.

[0068] Figure 4 The flowchart of another charging control method in the embodiment of the present disclosure is exemplarily shown. Figure 1 The difference of the charging control method 10 shown is that 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 high, Figure 4 The charging control method 20 shown in the figure further includes, before step S110:

[0069] In step S202, the voltage of the battery is detected.

[0070] For example, the current voltage of the battery can be detected by a detection module in the device to be charged.

[0071] In step S204, when the battery voltage is higher than the preset voltage threshold, the previously determined and adjusted charging current value is obtained, and the minimum value between the previously determined and adjusted charging current value and the determined target charging current value is selected as the current target charging current value.

[0072] By using this method, the charging current value to be adjusted is finally set to the smaller value between the charging current value determined last time and the charging current value to be adjusted determined this time. This can avoid the above-mentioned problem that when the battery voltage is high, the charging current value determined this time is higher than the charging current determined last time.

[0073] Figure 5 The flowchart of another charging control method in the embodiment of the present disclosure is exemplarily shown. Different from the above charging control methods, Figure 5 The charging control method shown further provides an embodiment of how to adjust the charging current of the battery in the device to be charged to the target charging current value, that is, Figure 5 The method shown is Figure 1 A further extension of step S110.

[0074] Those skilled in the art may understand that all or part of the steps for implementing the above embodiments are implemented as a computer program executed by the CPU or application processor (AP) of the device to be charged. When the computer program is executed by the CPU or AP, the above functions defined by the above method provided by the present disclosure are executed. Alternatively, all or part of the steps of the above embodiments may also be implemented as an executable code executed by a microcontroller unit (MCU) in the device to be charged. When the executable code is executed, the above functions defined by the above method are executed.

[0075] When the device to be charged includes both an AP and a control module implemented as an MCU, step S110 may include:

[0076] In step S1102, the target charging current value is sent to a 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 through the control module.

[0077] The control module may be implemented as the above-mentioned MCU, for example, to control the charging process of the device to be charged.

[0078] After receiving the charging current value, the control module can notify the power supply device to adjust the output current to the above charging current value.

[0079] The control module can communicate with the power supply device through the charging interface of the device to be charged. If the charging interface is a USB interface, the control module and the power supply device can communicate based on the data lines (such as D+ and / or D- lines) in the USB interface. For another example, if the charging interface is a USB interface that supports the PD communication protocol (such as a USB TYPE-C interface), the control module and the power supply device can communicate based on the PD communication protocol.

[0080] By communicating with the power supply device, the power supply device is notified to adjust the charging current to the above-mentioned charging current value that matches the type and application level of the power supply device.

[0081] Alternatively, the control module may be used to control the voltage conversion module in the device to be charged to adjust the charging current of the battery to the charging current value.

[0082] A voltage conversion module can be set in the device to be charged. Under the control of the control module, the voltage conversion module can convert the voltage and / or current output by the power supply device to adjust the charging current of the battery to the above-mentioned charging current value that matches the type and application level of the power supply device.

[0083] In some embodiments, the target charging current value can be sent to the control module in the device to be charged through a predefined field; wherein the field contains a predefined number of bits, and different values ​​are used to represent different target charging current values. Taking a 4-bit field as an example, 0x6 can represent a target charging current value of 6A, 0x5 can represent a target charging current value of 5A, 0x4 can represent a target charging current value of 4A, 0x3 can represent a target charging current value of 3A, etc. Through this predefined field, a variety of charging current values ​​to be adjusted can be indicated to the control module.

[0084] Figure 6 A flow chart of another charging control method in an embodiment of the present disclosure is exemplarily shown.

[0085] refer to Figure 6 , the charging control method 30 includes:

[0086] In step S302, the type of the power supply device connected to the device to be charged is obtained.

[0087] For example, the type of the power supply device may be acquired by communicating with the power supply device.

[0088] In step S304 , it is determined whether the type of the power supply device supports joint adjustment of current based on application level and temperature.

[0089] If the type of the power supply device does not support the combined adjustment of current based on the application level and temperature, the process proceeds to step S316 .

[0090] 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 .

[0091] In some embodiments, the determination in step S304 is performed only after confirming that the type of the power supply device supports fast charging, that is, the mechanism of jointly adjusting the charging current based on the application level and the temperature is only performed in the fast charging mode.

[0092] The following is an explanation of the "normal charging mode" and "fast charging mode" in the charging system.

[0093] Normal charging mode means that the power supply device (such as an adapter) outputs a relatively small current value (usually less than 2.5A) or charges the battery in the charging device with a relatively small power (usually less than 15W). In normal charging mode, it usually takes several hours to fully charge a large capacity battery (such as a 3000 mAh battery).

[0094] The fast charging mode means that the power supply device can output a relatively large current (usually greater than 2.5A, such as 4.5A, 5A or even higher) or charge the battery in the charging device with a relatively large power (usually greater than or equal to 15W).

[0095] Compared with the normal charging mode, the charging speed of the power supply device in the fast charging mode is faster, and the charging time required to fully charge a battery of the same capacity can be significantly shortened.

[0096] The power supply device can be a common type adapter, for example, a power supply adapter with a maximum output power of 10W (5V / 2A) and a common charging mode used to charge the device to be charged; or, the power supply device can be a fast charging adapter, for example, a high-power adapter with a maximum output power of 50W (10V / 5A) and a fast charging mode used to charge the device to be charged; or, the power supply device can also be another fast charging adapter, for example, a high-power adapter with a maximum output power of 20W (5V / 4A) and a fast charging mode used to charge the device to be charged.

[0097] In step S306, the type of application currently running in the device to be charged is detected, and the application level corresponding to the application of this type is determined.

[0098] In step S308 , based on the application level, a first charging current corresponding to the application level is determined.

[0099] In step S310, temperature information of the device to be charged is obtained, and a second charging current corresponding to the temperature information is determined.

[0100] 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.

[0101] In step S314, the charging current of the battery in the device to be charged is adjusted to a target charging current value.

[0102] In step S316, the charging current of the battery in the device to be charged is adjusted to a preconfigured charging current value.

[0103] The preconfigured charging current value may be, for example, a charging current value that matches the type of the power supply device.

[0104] In addition, it should be noted that the above figures are only schematic illustrations of the processes included in the method according to the exemplary embodiment of the present disclosure, and are not intended to be limiting. It is easy to understand that the processes shown in the above figures do not indicate or limit the time sequence of these processes. In addition, it is also easy to understand that these processes can be performed synchronously or asynchronously, for example, in multiple modules.

The voltage comparison module is used to obtain the charging current value determined and adjusted last time when the voltage is higher than a preset voltage threshold, and select the minimum value between the charging current value determined and adjusted last time and the determined target charging current value as the target charging current value this time.

[0119] In some embodiments, the charging current adjustment module 410 is used to send the target charging current value 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 through the control module.

[0120] In some embodiments, the charging current adjustment module 410 is used to send the target charging current value to the control module in the device to be charged through a predefined field; wherein the field contains a predefined number of bits, and different values ​​of the field are used to represent different target charging current values.

[0121] In some embodiments, the charging control device 40 further includes: a type acquisition device for acquiring the type of the power supply device connected to the device to be charged. The charging current adjustment module 410 is also used to adjust the charging current of the battery in the device to be charged to a preconfigured charging current value when the type of the power supply device does not support the joint adjustment of the current based on the application level and the temperature.

[0122] The charging control device provided in the embodiment of the present disclosure, during the charging process, refers to the target charging current value determined by a first charging current corresponding to the currently running application and a second charging current corresponding to the current temperature of the device to be charged, while taking into account the application scenario, temperature rise and charging speed. It can effectively control the temperature rise while ensuring the charging speed, thereby improving the charging efficiency and enhancing the user experience.

[0123] Furthermore, the charging control device provided in the embodiment of the present disclosure also designs a mechanism for dynamically adjusting the charging current of the battery based on temperature. When the temperature of the battery rises, the charging current value is reduced accordingly; and the reduction in charging current will cause the temperature of the battery to drop. When the temperature of the battery drops back, the charging current value is increased accordingly.
