Computer), mobile phone, MP3 player, MP4 players etc..
101st, current battery charge is obtained.
When terminal is connected by charging wire with power supply, the prompt window that terminal explicit reservation charges, when terminal judges go out
During user's selection reservation charging, terminal obtains battery dump energy from battery management system, so as to obtain current battery charge.
When reservation charging is cancelled in user's selection, terminal is charged according to normal charge mode.
102nd, according to the current battery charge, it is determined that the duration that charges accordingly.
Wherein, corresponding charging duration refers to the need for end cell is started to charge up to full charge amount by current electric quantity charging
Charging interval.
103rd, the charging complete moment set according to corresponding charging duration and user, it is determined that when charging starts
Carve.
Terminal calculates the moment corresponding with the difference of charging duration at charging complete moment that user is set, and the moment is fills
Establish the moment of beginning by cable.
Wherein, the charging complete moment that user is set is that user is set according to the demand of itself, it is desirable at this moment eventually
End-cell is charged to up to full charge amount.For example, after user selects reservation charging pattern, terminal allocating time function is obtained and used
The alarm time that family has been set, and current time is shown to user by the alarm time after phase inductive charging duration, so that
The charging complete moment that user is set；Or, by the user input charging complete moment.
Wherein, start time is charged for the charging complete moment of user preset is corresponding with the difference of corresponding charging duration
Moment.
It should be noted that it is contemplated that in charging process may due to the fluctuation of charging current, charging voltage etc.,
Or the influence charging rate such as other losses due to battery, cause end cell to fail to reach in user's setting time and completely fill
Electricity.To avoid problems, it is ensured that end cell reaches full charge amount at the charging complete moment that user is set, it is determined that filling
During electric start time, it is considered to certain reserved charging duration, that is, start time of charging is calculated for T=T0-t1-t0.Wherein, T is to fill
Electric start time；T0It is the preset charged deadline；t1It is the duration that charges accordingly；t0It is reserved charging duration.
104th, after start time is charged in arrival, charging is proceeded by.
Terminal real-time monitoring current time, and the current time that will be monitored with charge start time compare, it is determined whether
Reach start time of charging.
Supplementary notes, terminal is in standby or operation, it is necessary to consume battery electric quantity.Therefore, when it is determined that charging
When start time is more than the current time that terminal monitoring is arrived, then returns to step 101 and obtain current battery charge, then according to weight
The new current battery charge for getting, recalculates charging start time, it is determined that charging the moment for starting.
In embodiments of the present invention, when terminal is connected with power supply, by obtaining current battery charge, according to battery electric quantity
Corresponding charging duration is calculated, and the charging finishing time set with user according to the corresponding total charging duration of calculating, it is determined that
Charge start time, after start time is charged in arrival, just charged, so as to the whole mistake for ensureing to be connected with power supply in terminal
Cheng Zhong, only carries out once complete charging to terminal.Therefore, the embodiment of the present invention is avoided because terminal connects for a long time with power supply
When connecing, in the problem that relatively short time interior power can repeatedly be charged to the terminal of connection, improve battery and use the longevity
Life.
Further, to realize aforesaid operations, for step 102 according to current battery charge, it is determined that when charging accordingly
Realization long, the embodiment of the invention provides a kind of implementation method, as shown in Fig. 2 specifically including：
