Description

Technical Field

[0001] The present application relates to the technical field of mobile device battery management, and in particular to a backup battery charging control method, device, computer equipment and storage medium. Background Art

[0002] Modern mobile devices, such as smartphones, are usually equipped with a main battery and a backup battery. The main battery is responsible for the main power supply of the device, while the backup battery provides temporary power when the main battery is removed or exhausted to maintain the basic operation of the system and prevent data loss caused by sudden shutdown. However, the existing technology has some defects and shortcomings in the process of charging the main battery to the backup battery.

[0003] Existing charging schemes usually use a simple constant voltage and current charging method. For example, when the backup battery voltage is lower than 3.8V, it is charged through a constant power supply of 5V and 50mA (i.e., 0.25W power) until the battery is fully charged and the charging is triggered to be cut off. The pain point of charging at rated voltage and current (i.e., at constant charging power) is that the charging time is too long, resulting in a low voltage of the backup battery and an inability to provide stable power support at critical moments; due to low charging efficiency, long-term charging may cause abnormal conditions such as bulging of the backup battery, posing a safety hazard; during the charging process, the motherboard temperature is not effectively monitored, which may cause overheating and reduce the service life of the backup battery. Therefore, how to control the charging power according to the real-time status of the backup battery and thereby improve the reliability of the backup battery has become a technical problem that needs to be solved urgently.

[0024] The embodiments of the present application provide a backup battery charging control method, device, computer equipment and storage medium. The backup battery charging control method can be applied to a mobile terminal, and through the CPU usage and memory usage calculation components, the load type of the mobile terminal is intelligently identified, and a temperature detection component is introduced to monitor the temperature of the backup battery to achieve comprehensive intelligent adjustment of the charging power, thereby improving the reliability of the backup battery. The mobile terminal can be a smart phone, a portable computer or other mobile device that has a backup battery requirement.

[0025] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0026] See also Figure 1 , Figure 1 This is a schematic flow chart of a backup battery charging control method provided by an embodiment of the present application. The backup battery charging control method can be applied to a server, and is used to intelligently identify the load type of a mobile terminal through a CPU usage and memory usage calculation component, introduce a temperature detection component, monitor the temperature of the backup battery to achieve comprehensive intelligent adjustment of the charging power, and improve the reliability of the backup battery.

[0027] like Figure 1 As shown, the backup battery charging control method specifically includes steps S10 to S30.

[0028] Step S10: determining the CPU usage and memory usage of the mobile terminal by using the CPU usage calculation component and the memory usage calculation component respectively, and determining the load type of the mobile terminal according to the CPU usage and the memory usage;

[0029] Specifically, through the CPU usage calculation component, the total usage (tota l) and current usage (used) of the mobile terminal CPU are obtained, and the formula for calculating the CPU usage is as follows: CPU usage = used / tota l×100%; through the memory usage calculation component, the total capacity (tota l) and current used capacity (used) of the mobile terminal memory are obtained, and the formula for calculating the memory usage is as follows: memory usage = used / tota l×100%.

[0030] The load type of the current mobile terminal is determined based on the actual values ​​of the memory usage rate and the CPU usage rate. The load type classification rule is the load size. For example, the load can be divided into a high load type, a medium load type, and a low load type based on the memory usage rate and the CPU usage rate. More specifically, the load type can be determined based on the load threshold set by the user and compared with the current usage rate of the current mobile terminal.

[0031] For example, when both the CPU usage and the memory usage are low (for example, the CPU usage is ≤30%, the memory usage is ≤30%), it is determined to be a low load type;

[0032] When the CPU usage or memory usage is at a medium level (for example, CPU usage > 30% and ≤ 60%, memory usage > 30% and ≤ 60%), it is determined to be a medium load type;

[0033] When both the CPU usage and the memory usage are high (for example, CPU usage>60%, memory usage>60%), it is determined to be a high load type, wherein the specific values ​​are only examples and are not limiting.

[0034] Step S20, detecting the current battery voltage of the backup battery, and determining the current battery temperature of the backup battery through the temperature detection component;

[0035] Specifically, a voltage detection component is used to monitor the current voltage value of the backup battery in real time, and a temperature detection component (such as an NTC circuit) is used to obtain the current temperature value of the backup battery in real time.

[0036] Step S30: determining a target charging power of the charging management component according to the current battery voltage, the load type and the current battery temperature, wherein the charging power is the charging power of the main battery to the backup battery.

[0037] Specifically, when the load is low and the backup battery temperature is within a suitable range (e.g., 5°C-50°C), a higher charging power (e.g., 7V, 50mA) is selected according to the battery voltage for fast charging;

[0038] When the load is medium or the battery temperature is high (for example, 51°C-60°C), the charging power is appropriately reduced (such as 5V, 20mA) to balance charging efficiency and device safety.

[0039] When the load is high, or the battery temperature is too high (over 60°C) or too low (below 5°C), charging is stopped or a very low charging power (such as 5V, 20mA) is selected to protect the backup battery and the mobile terminal.

[0040] Specifically, the main battery in the mobile phone device is used to charge the backup battery more efficiently, safely and stably, ensuring that the backup battery can be fully charged for a long time as much as possible. In addition, the charging power is adjusted according to the load of the main battery to prevent the user from obviously feeling an abnormally rapid drop in power.

[0041] This embodiment discloses a backup battery charging control method, device, computer equipment and storage medium, the backup battery charging control method includes determining the CPU usage and memory usage of the mobile terminal through the CPU usage calculation component and the memory usage calculation component respectively, and determining the load type of the mobile terminal according to the CPU usage and the memory usage; detecting the current battery voltage of the backup battery, and determining the current battery temperature of the backup battery through the temperature detection component; determining the target charging power of the charging management component according to the current battery voltage, the load type and the current battery temperature, wherein the charging power is the charging power of the main battery to the backup battery. In the above manner, the present application intelligently identifies the load type of the mobile terminal through the CPU usage and memory usage calculation components, introduces the temperature detection component, monitors the temperature of the backup battery to achieve comprehensive intelligent adjustment of the charging power, and improves the reliability of the backup battery.

[0042] based on Figure 1 In the embodiment shown, in this embodiment, step S30 includes:

[0043] When the current battery voltage is greater than a preset battery voltage threshold, determining the target charging power to be 0;

[0044] When the current battery voltage is less than or equal to the preset battery voltage threshold, the target charging power of the charging management component is determined according to the load type and the current battery temperature.

[0045] Specifically, a voltage detection component is used to monitor the current voltage value of the backup battery in real time. According to the characteristics of the backup battery, a preset battery voltage threshold (for example, 4.2V) is set as a standard for judging whether the battery is close to a fully charged state. The detected current battery voltage is compared with the preset battery voltage threshold.

[0046] If the current battery voltage is greater than the preset battery voltage threshold, indicating that the backup battery is close to or has reached a fully charged state, the target charging power is determined to be 0, that is, charging is stopped. In this case, the target charging power of the charging management component is set to 0, and charging of the backup battery is stopped to prevent overcharging;

[0047] If the current battery voltage is less than or equal to the preset battery voltage threshold, it means that the backup battery is not fully charged and needs to be charged further.

[0048] When the load is low and the backup battery temperature is within a suitable range (e.g., 5°C-50°C), select a higher charging power (e.g., 7V, 50mA) for fast charging;

[0049] When the load is medium or the battery temperature is high (for example, 51°C-60°C), appropriately reduce the charging power (such as 5V, 30mA or 20mA) to balance charging efficiency and device safety;

[0050] When the load is high, or the battery temperature is too high (over 60°C) or too low (below 5°C), charging is stopped or a very low charging power (such as 5V, 20mA) is selected to protect the battery and the device.

[0051] Based on the above embodiment, in this embodiment, step S10 includes:

[0052] Determine a load type in which both the CPU usage rate and the memory usage rate are less than a preset first usage rate as a first load type;

[0053] Determine a load type in which the CPU usage rate or the memory usage rate is greater than the preset first usage rate and less than or equal to the preset second usage rate as a second load type;

[0054] The load type in which both the CPU usage rate and the memory usage rate are greater than the preset second usage rate is determined as a third load type.

[0055] Specifically, according to the performance and usage scenario of the mobile terminal, a preset first usage rate threshold (for example, 30%) is set as a standard for judging the low load state. Similarly, a preset second usage rate threshold (for example, 60%) is set as a dividing line for judging the medium load and high load states.

[0056] The calculated CPU usage and memory usage are compared with the preset first and second usage thresholds respectively.

[0057] If the CPU usage and the memory usage are both less than a preset first usage threshold (for example, both less than 30%), the current load type is determined as the first load type, indicating that the device is in a low load state;

[0058] If the CPU usage or the memory usage is greater than a preset first usage threshold and less than or equal to a preset second usage threshold (for example, greater than 30% and less than or equal to 60%), the current load type is determined as the second load type, indicating that the device is in a medium load state;

[0059] If both the CPU usage and the memory usage are greater than a preset second usage threshold (for example, both are greater than 60%), the current load type is determined as a third load type, indicating that the device is in a high load state.

[0060] Based on the above embodiment, in this embodiment, when the current battery voltage is less than or equal to the preset battery voltage threshold, determining the target charging power of the charging management component according to the load type and the current battery temperature includes:

[0061] Determining battery temperature gear information of the current battery temperature according to a preset battery temperature grouping rule and the current battery temperature;

[0062] The target charging power is determined according to the battery temperature gear information and the load type.

[0063] Based on the above embodiment, in this embodiment, determining the target charging power according to the battery temperature gear information and the load type includes:

[0064] When the battery temperature gear information is the first temperature gear information and the load type is the first load type, determining that the target charging power is a first gear charging power;

[0065] When the battery temperature gear information is the first temperature gear information and the load type is the second load type or the third load type, determining that the target charging power is the second gear charging power;

[0066] When the battery temperature gear information is the second temperature gear information and the load type is the first load type or the second load type, determining that the target charging power is the second gear charging power;

[0067] When the battery temperature level information is the second temperature level information and the load type is the third load type, the target charging power is determined to be the third level charging power.

[0068] In one embodiment, specifically, because the charging efficiency and safety of the battery may be affected in a low or high temperature environment, a lower charging power (such as 5V, 20mA) is selected or charging is stopped to prevent battery damage.

[0069] In the case of a first load type (i.e., low load), a higher charging power is determined for fast charging;

[0070] In the case of the second load type (i.e., medium load), a medium charging power is determined to balance the charging efficiency and the device load;

[0071] In the case of the third load type (ie, high load), a lower charging power is determined or charging is stopped to avoid excessive burden on the device.

[0072] Further, when the current battery voltage is less than or equal to the preset battery voltage threshold, determining the target charging power of the charging management component according to the load type and the current battery temperature includes:

[0073] When the CPU usage rate is greater than a preset usage rate threshold, the target charging power is determined to be 0.

[0074] Further, when the current battery voltage is less than or equal to the preset battery voltage threshold, determining the target charging power of the charging management component according to the load type and the current battery temperature includes:

[0075] When the current battery temperature exceeds a preset battery temperature threshold, the target charging power is determined to be 0.
