To maintain the following description of the embodiments of the present invention clear and concise, a detailed description of known functions and known components of the invention have been omitted.
A first embodiment of the present invention provides a power supply management method, a flow of which is shown in fig. 1, including steps S101 to S103:
s101, acquiring the current system power of the terminal.
S102, detecting whether the current system power is larger than the preset system power.
And S103, under the condition that the input power is larger than the preset system power, adjusting the input power of the terminal from the default power to the peak power so as to improve the input current value.
The method can be applied to a terminal which is provided with an adapter and a battery at the same time, the structure of the terminal is schematically shown in FIG. 2, and the adapter supplies power to a system mainboard; the CPU is connected with a shutdown protector and an EC (embedded controller) respectively, the shutdown protector outputs a throttle signal to the CPU, and the EC controls the throttle signal to adjust the working frequency of the CPU; the EC is also connected to an adapter and a charging chip (Charge IC), and sets input power (also input current) to the charging chip and transmits an adjustment signal to the adapter.
The predetermined system power is generally less than or equal to the rated power of the adapter, for example, the rated power of the adapter is 125W, and the predetermined system power can be set to 120W. If the current system power is greater than 120W, it is likely that the adapter is plugged in to supply power, but the battery is also in a discharge state, so in order to reduce the discharge of the battery, the amount of power that can be input by the adapter, that is, the input power, and thus the input current, needs to be adjusted.
According to the embodiment of the invention, when the current system power of the terminal is greater than the preset system power, the input power is adjusted from the default power to the peak power, and then the input current value is adjusted, so that the adapter can provide more electric energy, the battery discharge is reduced or prevented, and the user experience is better.
If the current system power is always high, the adapter needs to input with the peak power all the time to meet the requirement of the adapter for more power supply, however, the mode of inputting with the peak power all the time is an injury to the adapter.
Based on the above considerations, after the input power of the terminal is adjusted from the default power to the peak power, on the basis of fig. 1, the flowchart may also be shown in fig. 3, and further includes the following steps:
and S104, detecting whether the current system power is larger than the peak power. If so, S105 is performed, otherwise, S107 is performed.
And S105, detecting whether the time greater than the peak power exceeds a first preset time or not under the condition of being greater than the peak power, wherein the first preset time is less than or equal to the sustainable time of the peak power. If so, S106 is executed, otherwise, S107 is executed.
And S106, under the condition that the first preset time is exceeded, adjusting the input power from the peak power to the average power, and setting the average power for a second preset time.
Through the scheme, the adapter can supply power by using a proper input current, and the condition that the battery supplies power to the terminal can be reduced or prevented to the greatest extent when the input current is used for supplying power. In a specific implementation, if the sustainable time is 0.5S, the first predetermined time may be set to 0.4S, and the first predetermined time being less than or equal to the sustainable time can ensure that the adapter is not always in the peak power for input, which is a protection measure for the adapter.
S107, the input power is maintained at the peak power.
If the time that the current system power is greater than the peak power does not exceed the first predetermined time, it indicates that the current system power is not so large that the current system power needs to be maintained at the peak power, therefore, even if the input power is set to the peak power, the adapter does not always perform power supply according to the peak power, but performs power supply according to the current system power, and the peak power is only a set threshold value, so that the input power can be maintained at the peak power.
In the implementation, in order to protect the adapter, the input voltage of the adapter can be acquired periodically or aperiodically; detecting whether the input voltage is lower than a predetermined voltage threshold; and in the case of being lower than the preset voltage threshold, reducing the working frequency of the terminal from the default frequency to the preset frequency, and setting the preset frequency for a third preset time, otherwise, maintaining the working frequency of the terminal at the default frequency.
When the terminal is always in high-power operation, the adapter always needs to be fully loaded to supply power to the terminal, and if the time is long, the adapter easily breaks down and directly shows that the voltage can be obviously reduced.
Regardless of how the input power is adjusted as described above, after the adjustment, a power adjustment signal is transmitted to the adapter so that the adapter changes the current value of the input terminal in accordance with the power adjustment signal.
This example takes full advantage of the PK Power of the adapter to reduce the frequency of Turbo discharge of the battery without increasing the size of the adapter, thereby optimizing the problem of battery Power degradation with the adapter inserted. The values of PK power and Continue power are given by the adapter manufacturer or are dynamically stored in the adapter registers according to the actual application of the adapter. For example, PK power is defined as 0.5S in the adapter, and EC detects PSYS (system power) 10ms each time, and the adapter setting at 135W is to adjust the battery stop and discharge point back when the system power consumption is greater than 120W, which is somewhat buffered with 125W (135W adapter normal battery stop). Since the hardware limit of the EC is only one detection in 10ms, the PK power below 10ms is still discharged when the discharge point is exceeded.
The actual values of the peak power and the average power can be 0.93 times of the peak power and the average power, and therefore the terminal protection function is achieved.
The core of the embodiment of the invention is to dynamically adjust the charging stop point and the discharging stop point of the battery by using the PK power and the Continue power (average power) of the adapter, thereby optimizing the problem of battery power reduction caused by PK value in the game process of the battery. For example, an adapter which originally needs to use 150W can only use 135W by the method, or the battery capacity can be reduced by 20% when 135W is continuously played for 2 hours, and the battery current can be reduced by only 5% after the scheme is optimized. The CPU entering the power-saving mode is a protection action for the adapter, and the system is prevented from being overloaded and stopping working.
A second embodiment of the present invention provides a power supply management apparatus, a structural schematic of which is shown in fig. 4, including:
an obtaining module 10, configured to obtain a current system power of a terminal; a detecting module 20, coupled to the obtaining module 10, for detecting whether the current system power is greater than a predetermined system power; and an adjusting module 30, coupled to the detecting module 20, for adjusting the input power of the terminal from the default power to the peak power to increase the input current value if the input power is greater than the predetermined system power.
If the current system power is always high, the adapter needs to input with the peak power all the time to meet the requirement of the adapter for more power supply, however, the mode of inputting with the peak power all the time is an injury to the adapter.
Based on the above considerations, the detection module is further configured to detect whether the current system power is greater than the peak power; if the time is larger than the peak power, detecting whether the time larger than the peak power exceeds a first preset time, wherein the first preset time is smaller than or equal to the sustainable time of the peak power; the adjusting module is further configured to adjust the input power from the peak power to the average power and set the average power for a second predetermined time if the first predetermined time is exceeded.
Through the scheme, the adapter can supply power by using a proper input current, and the condition that the battery supplies power to the terminal can be reduced or prevented to the greatest extent when the input current is used for supplying power. In a specific implementation, if the sustainable time is 0.5S, the first predetermined time may be set to 0.4S, and the first predetermined time being less than or equal to the sustainable time can ensure that the adapter is not always in the peak power for inputting, which is a protection measure for the adapter.
If the time that the current system power is larger than the peak power does not exceed the first predetermined time, it indicates that the current system power is not so large that the current system power needs to be maintained at the peak power, therefore, even if the input power is set to the peak power, the adapter does not always supply power according to the peak power, but supplies power according to the current system power, and the peak power is only a set threshold value, so the input power can be maintained at the peak power.
If the time that the current system power is larger than the peak power does not exceed the first predetermined time, it indicates that the current system power is not so large that the current system power needs to be maintained at the peak power, therefore, even if the input power is set to the peak power, the adapter does not always supply power according to the peak power, but supplies power according to the current system power, and the peak power is only a set threshold value. Therefore, the adjusting module is further configured to maintain the input power at the peak power if the first predetermined time is not exceeded.
In the implementation process, the acquisition module is used for protecting the adapter and also used for acquiring the input voltage of the adapter; the detection module is also used for detecting whether the input voltage is lower than a preset voltage threshold value; and the adjusting module is used for reducing the working frequency of the terminal from the default frequency to the preset frequency and setting the preset frequency for a third preset time under the condition of being lower than the preset voltage threshold.
The above apparatus may further include: and the transmitting module is used for transmitting the power adjusting signal to the adapter so that the adapter changes the current value of the input terminal according to the power adjusting signal.
The core of the embodiment of the invention is to dynamically adjust the charging stop point and the discharging stop point of the battery by using the PK power and the Continue power (average power) of the adapter, thereby optimizing the problem of battery power reduction caused by PK value in the game process of the battery. For example, an adapter which originally needs to use 150W can only use 135W by the method, or the battery capacity can be reduced by 20% when 135W is continuously played for 2 hours, and the battery current can be reduced by only 5% after the scheme is optimized. The CPU entering the power-saving mode is a protection action for the adapter, and the system is prevented from being overloaded and stopping working.
