Description

[Technical Field]

The application of hardware such as high-power chargers, high-performance processors (Central Processing Units, or CPUs), and high-refresh-rate liquid crystal displays (LCDs) is becoming increasingly common in terminals. While these technologies improve user experience, they also bring significant power supply and heat generation issues to terminals. For example, when a device's battery is very low, users have no choice but to plug in a charger to maintain the remaining power if they need to continue using the device at high intensity. Charging while still using a high-power device not only affects the normal power supply of the terminal system, but also causes rapid heating due to the combined effects of temperature rise caused by charging and high load, resulting in issues such as CPU frequency limitations and system lag, significantly impairing the user experience.

DETAILED DESCRIPTION OF THE INVENTION

[0013] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application will be described in more detail below with reference to the drawings and examples. It should be understood that the examples described herein are only used to interpret the present application, and are not used to limit the present application.

[0014] In the description of the embodiments of the present application, the terms "first," "second," etc. are merely intended to distinguish technical features and should not be understood as indicating or implying relative importance, implicitly indicating the number of listed technical features, or implicitly indicating the context of listed technical features. "At least one" means one or more, and "plurality" means two or more. "And / or" describes a relationship between related objects and indicates that a three-way relationship can exist. For example, A and / or B can represent the cases where A exists alone, A and B exist simultaneously, or B exists alone. A and B may be singular or plural. The symbol " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" and similar expressions refer to any combination of these items, including any combination of singular or plural. For example, at least one of a, b, and c represents a, b, and c, a and b, a and c, b and c, or a, b, and c, where a, b, and c may be singular or plural.

[0015] Furthermore, the technical features according to the embodiments of the present application described below may be combined with each other as long as they do not cause mutual contradictions.

[0016] The charging control method according to the embodiment of the present application is based on a programmable power supply (PPS) protocol. To meet the charging requirements of various terminals in various application scenarios, the charger output power needs to be adjusted, thereby achieving functions such as battery protection and terminal temperature control. In practical applications, with the continuous improvement of charger performance, the power consumption of individual terminal components is increasing, and the requirements for charging control are becoming more stringent depending on the terminal's performance and charging efficiency. Therefore, using a scientific and rational charging control method can more effectively maximize the terminal's performance in a charging state, especially when the terminal is operating under high loads. This not only ensures the terminal's performance, but also effectively improves the terminal's charging efficiency. For example, a typical charging control scenario is when the terminal's battery level is very low, and if the terminal needs to continue using at high intensity, the only option is to connect the charger to maintain the remaining level. In such a scenario where charging is performed while the power consumption is high, the temperature rise due to charging and the temperature rise due to high loads often combine to cause the terminal to rapidly heat up.

[0017] To ensure safe device charging, the conventional charging control method calculates the charging current required by the battery based on factors such as battery temperature and remaining charge, and then sets the charger's output current according to the battery's charging requirements. The problem with this control method is that when the system load is heavy, the heat generated by the processor and charging combine to cause a rapid rise in the overall system temperature. When the temperature rises, various protection operations are usually triggered, such as reducing the CPU clock frequency, reducing the LCD brightness, and reducing the charging current, to achieve the goal of cooling. However, these protection operations significantly limit the device's performance and degrade the user experience.

[0018] To ensure the performance of mobile phones while they are charging, some mobile phone manufacturers provide a separate charging control mode to solve the problem of overheating during charging when the battery is low or under heavy load. When this mode is enabled, the charger does not charge the battery at all after connecting the charger, but instead provides power for system consumption. This method reliably achieves battery temperature control while ensuring the performance of the mobile phone. However, the problem with this method is that under heavy loads, the battery cannot be charged all the time, so the charger cannot increase the battery's remaining capacity, causing the battery to remain in a low state and causing damage. Furthermore, users cannot be separated from the charger when using their devices, which causes a lot of inconvenience to users.

[0019] In view of the above circumstances, the embodiments of the present application provide a charging control method, device, electronic device, and computer-readable storage medium, which determine the charging power requirement of a battery according to the temperature controlled charging current value of the battery, determine charging parameters according to the system power consumption value and the charging power requirement, and determine the charging output power of a charger according to the charging parameters, so that the charger charges the terminal according to the charging output power, thereby effectively alleviating the contradiction between system power supply and battery charging under high-load operating conditions, maintaining stable power supply and temperature control to the terminal, and ensuring charging stability of the terminal on the premise of ensuring user experience.

[0020] Referring to Figure 1, Figure 1 shows the process of the charging control method according to the embodiment of the present application. As shown in Figure 1, the charging control method according to the embodiment of the present application includes the following steps:

[0021] S1000: The system power consumption value of the terminal is acquired.

[0022] The power consumption value of each major component of a terminal can be directly obtained through conventional terminal detection software, and the power consumption values ​​of the major power-consuming components of the terminal can be periodically collected and collected as statistics and then combined to obtain the system power consumption value of the terminal. Because obtaining the power consumption value of each component of a terminal through detection software is a conventional technology, a detailed description thereof will be omitted here.

[0023] For example, the major components of a mobile device include the display screen, CPU, sensors, camera, and speaker. Among these, the display screen generates heat and is bright during operation. Most current mobile device display screens have a resolution of 1080P or higher, consuming a large amount of power during extended use. Furthermore, all mobile device operations are controlled by the CPU, and the CPU's performance directly determines the mobile device's system performance. The CPU performs several basic functions, such as data communication, resource sharing, distributed processing, and system reliability. Therefore, the display screen and CPU are the mobile device components that consume the most power during normal use. Of course, in some specific scenarios, the power consumption of other components may also account for a large portion of the mobile device's system power consumption. For example, if you use the camera for a long time to take pictures and the speaker for a long time to play music, the camera and speaker are the major power-consuming components. The sum of their power consumption values ​​can be calculated to obtain the device's system power consumption value.

[0024] In practical applications, in order to facilitate real-time calculation of the system power consumption value of the terminal, the system power consumption value of the terminal may be the input power of the charger minus the actual charging power of the battery, and the calculation formula is as follows:

[0025]

number

[0026] S2000: Determine that the terminal is being charged via a charger and is in a high-load operating state, determine the charging power requirement of the battery according to the temperature-controlled charging current value of the battery, and determine charging parameters according to the system power consumption value and the charging power requirement, where the temperature-controlled charging current value is the maximum current value of the battery that can be charged without generating heat.

[0027] 2 and 3, both of which show a schematic diagram of the implementation process of the above step S2000. As shown in FIGS. 2 and 3, step S2000 includes at least the following steps:

[0028] S2100: It is determined that the terminal is being charged via a charger.

[0029] The terminal determines whether the terminal is connected to a power source through a charger by detecting the input voltage value and input current value of the charging interface. For example, the terminal can determine whether the battery is being charged through a charger by collecting the battery status through the charging chip, for example, by determining whether the battery has a charging voltage or charging current and whether the remaining battery power is increasing, to determine that the terminal is connected to a power source through a charger, that the charger is powering the terminal components, and that the charger is charging the battery through the charging chip.

[0030] S2200: It is determined that the terminal is in a high-load operating state, and the charging power requirement of the battery is determined according to the temperature-controlled charging current value of the battery.

[0031] Referring to Figure 4, Figure 4 shows a schematic diagram of the implementation process of the above step S2200. As shown in Figure 4, step S2200 includes at least the following steps:

[0032] S2210: It is determined that the terminal is in a high-load operating state.

[0033] A high-load operating state refers to a state in which a device is consuming high power due to a high resource utilization rate of key components. For example, when a mobile device runs multiple application programs or programs that occupy a large amount of CPU and memory resources, such as large-scale games, cameras, or image processing software, the mobile device will consume a lot of power and generate a lot of heat. To prevent damage to core components due to excessive temperatures when a device is operating under high load, protection mechanisms such as turning on heat-dissipating components, limiting CPU output performance, reducing display screen brightness, or forcibly shutting down the device will generally be implemented to keep the device temperature within a safe range.

[0034] Referring to Figure 5, Figure 5 shows a schematic diagram of the implementation process of the above step S2210. As shown in Figure 5, step S2210 includes at least the following steps:

[0035] S2211: The system power consumption value is compared with the power threshold.

[0036] The power threshold is a predetermined value, and its magnitude reflects whether the terminal is currently in a high-load operating state. Therefore, the terminal's power threshold needs to be adjusted and matched according to the hardware configuration, software configuration, and operating environment so as to accurately represent the terminal's operating state. For example, if the power threshold of a mobile terminal is 8W and the terminal is being charged via a charger, if the current system power consumption value is greater than 8W, the mobile terminal is determined to be in a high-load operating state.

[0037] S2216: It is determined that the terminal is in a high-load operating state.

[0038] If the system power consumption value is greater than the power threshold, the value obtained by subtracting the actual charging power of the battery from the input power of the charger is greater than the power threshold, the main components of the terminal are in a high power consumption state, the proportion of the system power consumption value that accounts for the input power of the charger is increasing, and it is determined that the terminal is in a high-load operating state.

[0039] In another embodiment, step S2210 includes at least the following steps:

[0040] S2212: The processor occupation rate of the terminal is acquired.

[0041] Processor occupancy refers to the processor resources occupied by programs executed by a terminal, and indicates the status of the terminal's program execution at a particular time. A higher processor occupancy indicates that the terminal is currently running more programs, and vice versa. Therefore, the magnitude of processor occupancy can directly reflect the operating status of the terminal. Conventional terminal detection software can regularly and accurately obtain processor occupancy, and can also timely determine the current operating status of the terminal.

[0042] S2213: The processor occupancy rate of the terminal is compared with the occupancy rate threshold.

[0043] The occupancy threshold is also a predetermined value, and its magnitude reflects whether the terminal is currently in a high-load operating state. Therefore, the terminal occupancy threshold needs to be adjusted and matched according to the hardware configuration, software configuration, and operating environment so as to accurately represent the terminal's operating state. For example, if the occupancy threshold of a mobile terminal is 30%, and the terminal is being charged via a charger, if the current terminal processor occupancy is greater than 30%, the mobile terminal is determined to be in a high-load operating state.

[0044] S2216: It is determined that the terminal is in a high-load operating state.

[0045] When the processor occupancy rate of the terminal is greater than the occupancy rate threshold, the processor is in a high-power consumption operating state. For example, all operations of a mobile terminal are controlled by the processor, and the processor's performance indicators directly determine the system performance indicators of the mobile terminal. Therefore, when the processor occupancy rate of the terminal is greater than 30%, it indicates that the processor and other core components are in a high-power consumption state, and the terminal is determined to be in a high-load operating state.

[0046] In another embodiment, step S2210 includes at least the following steps:

[0047] S2214: The continuous display time of the display screen of the terminal is acquired.

[0048] The continuous display time of a terminal's display screen is the time during which the display screen running on the terminal is continuously in operation, and indicates that the terminal is in operation during this period. In particular, with the popularity of LCD screens with high refresh rates, the proportion of power consumption by the display screen of a mobile terminal is becoming increasingly higher. The longer the continuous display time of the terminal's display screen, the more power the terminal consumes during this period. Therefore, the length of the continuous display time of the display screen can directly reflect the operating state of the terminal. Conventional terminal detection software can obtain the continuous display time of the display screen in real time, and further determine the current operating status of the terminal in a timely manner.

[0049] S2215: The continuous display time of the display screen of the terminal is compared with the time threshold.

[0050] The time threshold is also a predetermined value, and its magnitude reflects whether the terminal is currently in a high-load operating state. Therefore, the time threshold of the terminal needs to be adjusted and matched according to the display screen resolution and operating environment so as to accurately represent the terminal's operating state. For example, if the time threshold of a mobile terminal is 30 minutes and the terminal is being charged via a charger, if the continuous display time of the terminal's display screen is longer than 30 minutes, the mobile terminal is determined to be in a high-load operating state.

[0051] S2216: It is determined that the terminal is in a high-load operating state.

[0052] If the continuous display time of the display screen of the terminal is longer than the time threshold, the display screen of the terminal is in a long-term operating state. For example, the power consumption of the display screen of a mobile terminal accounts for a significant proportion of the terminal's system power consumption value, so the continuous operating time of the display screen directly determines the power consumption value of the mobile terminal. Therefore, if the continuous display time of the display screen is longer than 30 minutes, it indicates that both the display screen and the mobile terminal are in a high power consumption state, and further, it is determined that the terminal is in a high-load operating state.

[0053] In practical applications, in order to improve the timeliness and accuracy of determining whether the terminal is in a high-load operating state, one or more different conditions in steps S2211, S2213, and S2215 may be combined for the determination. That is, if at least one of the following is met: the system power consumption value is greater than a power threshold; the processor occupancy rate of the terminal is greater than an occupancy rate threshold; and the continuous display time of the display screen of the terminal is longer than a time threshold, it can be determined that the terminal is in a high-load operating state.

[0054] In step S2210, in addition to the system power consumption value, the terminal processor occupancy rate, and the continuous display time of the terminal display screen as the basis for determining whether the terminal is in a high-load operating state, other operating parameters of the terminal may also be used as the basis for determination. For example, operating parameters such as the terminal random access memory occupancy rate and the current temperature of the terminal CPU may also be used as the reference indicators for determining whether the terminal is in a high-load operating state, and the determination process is the same as that of step S2210 above, and a detailed description thereof will be omitted here.

[0055] S2220: The maximum current value is obtained.

[0056] Referring to Figure 6, Figure 6 shows a schematic diagram of the implementation process of the above step S2220. As shown in Figure 6, step S2220 includes at least the following steps:

[0057] S2221: In a constant temperature environment, charge the battery with different rated charging currents, and ensure that the temperature increase value of the battery within a predetermined time is less than the temperature threshold value.

[0058] Because the battery performance is relatively stable, when a certain charging current is input, the battery temperature rise value can be controlled within a certain range. Furthermore, on the premise of ensuring battery charging efficiency, the battery temperature rise can be effectively suppressed, preventing the battery temperature from rising too quickly during charging and affecting other components of the terminal.

[0059]

number

[0060] S2222: The maximum value from the different rated charging currents is selected as the maximum current value at which the battery can be charged without generating heat.

[0061]

number

[0062] S2230: The charging request power is determined according to the temperature control charging current value and the input voltage value of the battery.

[0063]

number

[0064]

number

[0065] S2300: Determine that the terminal is in a low-load operating state, and obtain a charging request power according to the battery's technical parameters and current remaining capacity.

[0066] The low-load operating state refers to a state in which the terminal is in a low-power consumption state due to a low resource occupancy rate of a major component. The process of determining whether the terminal is in a low-load operating state may refer to step S2210 above. If the terminal does not meet the conditions for the high-load operating state, the terminal can be determined to be in a low-load operating state. For example, if the system power consumption value is less than a power threshold, the terminal's processor occupancy rate is greater than an occupancy rate threshold, and the continuous display time of the terminal's display screen is shorter than a time threshold, the terminal can be determined to be in a low-load operating state.

[0067]

number

[0068]

number

[0069]

number

[0070] S2400: Charging parameters are determined according to the system power consumption value and the charging request power.

[0071] Referring to Figure 7, Figure 7 shows a schematic diagram of the implementation process of the above step S2400. As shown in Figure 7, step S2400 includes at least the following steps:

[0072]

number

[0073]

number

[0074] By adding the system power consumption value and the charging request power to obtain the total output power, it is possible to ensure that the charger supplies the power required for the terminal system and output stable charging power to the battery, which not only avoids performance limitations of the terminal due to insufficient power supply or excessively rapid heat generation, but also ensures battery charging efficiency.

[0075] S2420: The output voltage of the charger is determined according to the input voltage value of the battery.

[0076]

number

[0077]

number

[0078] S2430: Determine the output current of the charger according to the total output power and the output voltage of the charger.

[0079]

number

[0080] S2440: Determine charging parameters according to the output voltage and output current of the charger.

[0081] After obtaining the charger's output voltage and output current, the charger can be controlled to output the corresponding voltage and current values, so that the charger's output power meets the terminal's charging requirements and ensures battery temperature control and terminal performance. In practical applications, it is necessary to further compare the total output power with the charger's maximum output power to ensure that the charger charges the battery within a safe range and avoid safety risks caused by charger overload operation. When it is ensured that the charger's output voltage and output current are both within the charger's performance parameters, the charger's charging parameters are determined.

[0082] S3000: Determine the charging output power of the charger according to the charging parameters, so that the charger charges the terminal according to the charging output power.

[0083] After determining the charging parameters, the terminal sends a charging request to the charger, and the charger charges the terminal according to the charger's output voltage and charger's output current, and further ensures that the charger supplies power to the terminal peripheral devices and charges the battery according to the charging output power.

[0084]
