In order to keep the following explanation of the embodiment of the present invention to understand and simplicity, present invention omits known functions and known portion
The detailed description of part.
First embodiment of the invention provides a kind of power supply management method, and the process of this method is as shown in Figure 1, include step
S101 to S103:
S101 obtains the current system power of terminal.
S102, detects whether current system power is greater than reservation system power.
The input power of terminal is adjusted to peak value by default power in the case where being greater than reservation system power by S103
Power, to promote input current value.
This method can be applied in the terminal at the same time with adapter and battery, the structural representation of the terminal such as Fig. 2 institute
Show, adapter is system board power supply；CPU is separately connected with turn-off protector and EC (embedded controller), turn-off protector
Throttle signal (throttle signal) is exported to CPU, EC controls the throttle signal with the work frequency for adjusting CPU
Rate；EC is also connect with adapter and charging chip (Charge IC), to charging chip setting input power (and input electricity
Stream), adjustment signal is sent to adapter.
Above-mentioned reservation system power is typically less than or equal to adapter rated power, for example, the rated power of adapter is
125W, then reservation system power can be set to 120W.If current system power is greater than 120W, illustrate to be likely occurred slotting
Adapter power supply but battery also in the state of electric discharge, therefore, in order to reduce the electric discharge of battery, needing to adjust adapter can
The electricity of input, i.e. adjustment input power, and then adjust input current.
The embodiment of the present invention is when the current system power of terminal is greater than reservation system power, i.e., by input power by default
Power adjustment is peak power, and then adjusts input current value, and Lai Shixian adapter is capable of providing more electric energy, reduce or
Prevent battery discharge, better user experience.
If current system power is higher always, adapter needs to be inputted with peak power always, ability
Enough meet adapter to power the needs of more, is one for adapter however, being constantly in the mode that peak power is inputted
Kind injury.
Based on above-mentioned thinking, the embodiment of the present invention by the input power of terminal by default power be adjusted to peak power it
Afterwards, on the basis of Fig. 1, above-mentioned flow chart can be as shown in figure 3, further include following steps:
S104, detects whether current system power is greater than peak power.If it is, executing S105, otherwise, execute
S107。
S105, in the case where being greater than peak power, whether detection is greater than the time of peak power more than the first pre- timing
Between, wherein the first predetermined time was less than or equal to the sustainable time of peak power.If it is, S106 is executed, otherwise,
Execute S107.
Input power is adjusted to mean power by peak power more than the first predetermined time by S106, and
Setting mean power continued for the second predetermined time.
Through the above scheme, adapter can be made with a more appropriate input current power supply, with input electricity
When stream power supply, can reduce or prevent to the greatest extent battery is the case where terminal is powered.When specific implementation, the sustainable time
If it is 0.5S, the first predetermined time can be set to 0.4S, and the first predetermined time was less than or equal to the sustainable time can
Guarantee that adapter will not be constantly in peak power and be inputted, is a kind of safeguard measure to adapter.
Input power is maintained peak power by S107.
If explanation is worked as in the case that the time that current system power is greater than peak power was less than for the first predetermined time
Preceding system power is not sufficiently large to need to maintain peak value power supply always, therefore, even if input power is set as peak power,
Adapter will not be powered according to peak power always, but be powered according to current system power, peak value
Power is only the threshold value of a setting, it is possible to which input power is maintained peak power.
When realization, in order to protect adapter, can also periodically or non-periodically acquisition adapter input voltage；It detects defeated
Enter whether voltage is lower than predetermined voltage threshold；In the case where being lower than predetermined voltage threshold, by the working frequency of terminal by default
Frequency is reduced to preset frequency, and preset frequency is arranged and continues the third predetermined time, and otherwise, the working frequency of terminal is maintained
Default frequencies.
When terminal is constantly in higher-wattage work, for adapter there is a continuing need for being at full capacity that terminal is powered, the time is more long
If, adapter is easy to break down, and being embodied directly in voltage can be substantially reduced, therefore, test adaptor in above scheme
Input voltage with the presence or absence of variation, if when input voltage is when being lower than predetermined voltage threshold, illustrate adapter may
There is the case where can't bear load, needs to reduce the working frequency of terminal CPU at this time, and then reduce the system power of terminal, then fit
Meeting for orchestration can be eased, and prevent damage adapter.
No matter it is above-mentioned how to adjust input power, after the adjustment, all power adjustment signal is sent to adapter, so that suitable
Orchestration changes the current value of input terminal according to power adjustment signal.
This fact Example makes full use of the PK Power (Peak of adapter the size of not increased adapter the case where
Power, peak power) frequency that battery Turbo discharges is reduced, so that battery capacity declines in the case that adapter is inserted in optimization
The problem of.Adapter manufacturer provides the value of PK power and Continue power or the practical situations according to adapter
There are in adapter register for dynamic.For example, defining PK power in adapter is 0.5S, and EC is to PSYS (system power)
The detecting time be 10ms it is each, while the setting of the adapter in 135W be when system power dissipation be greater than 120W when after battery is turned up
Stop punching point and point of discharge, there are also certain bufferings for this and 125W (135W adapter normal battery stops rushing a little).It is hard due to EC
Part limitation can only accomplish that 10ms detecting is primary, put so PK power below to 10ms still will do it when being more than point of discharge
Electricity.
The actual value of above-mentioned peak power and mean power all can be 0.93 times peak power and mean power, into
And realize the defencive function to terminal.
The core of the embodiment of the present invention be using PK power and the Continue power (mean power) of adapter come
