Based on above-mentioned mobile terminal hardware configuration and communication system, one embodiment of charging method of the present invention is proposed.Such as
Shown in Fig. 3, it the described method comprises the following steps：
S11, the temperature T for obtaining battery.
The size of S12, comparison temperature T and the first critical-temperature Tn, judge whether temperature T is more than the first critical-temperature Tn.
Work as T>When Tn, step S13 is executed；As T≤Tn, step S15 is executed.
Wherein, the first critical-temperature Tn is preset temperature value.
S13, judge whether terminal is in use state.When terminal is in use state, step S14 is executed；Work as terminal
When in non-working condition, step S15 is executed.
Wherein, whether terminal is in the specific judgment method of use state, will be described in detail later.
S14, setting maximum temperature Ts are equal to the first critical-temperature Tn.
Wherein, the Limit temperature value for allowing battery to reach when maximum temperature Ts is charging.When battery temperature T faces more than first
Boundary temperature Tn and when terminal is in use state, then be arranged Ts=Tn.
S15, setting maximum temperature Ts are equal to the second critical-temperature Tm.
Wherein, the second critical-temperature Tm is preset another temperature value, and Tm>Tn.When battery temperature T is less than or equal to the
One critical-temperature Tn, or when battery temperature T is more than the first critical-temperature Tn and terminal is in non-working condition, then Ts is set
=Tm.
The size of S16, comparison temperature T and maximum temperature Ts, judge whether T is more than Ts.Work as T>When Ts, step S17 is executed；
When T is not more than Ts, step S18 is executed.
S17, reduce charging current.
In this step S17, when battery temperature T is more than maximum temperature Ts, illustrate that current battery temperature is excessively high, has been more than electricity
Limit temperature value when pond is charged, therefore reduce charging current, prevent terminal from overheating.
S18, judge whether T is less than Ts-K.Work as T<When Ts-K, step S19 is executed, flow is otherwise terminated.
Wherein, K is preset constant, and K >=0, specific size can set according to actual needs.
S19, increase charging current.
In this step S19, when battery temperature T is less than maximum temperature Ts certain values (K), then increase charging current, to carry
High charge speed.
The sequencing of step S16 and step S18 can also exchange, i.e., first judge whether T is less than Ts-K, when T is not less than
When Ts-K, then judge whether T is more than Ts.
In the present embodiment, after step S17, after step S19 or after terminating flow, interval preset time returns again to
Step S11.That is, in the present embodiment, one-shot battery temperature T is detected every preset time, a charging current is adjusted, so recycles
Back and forth.In step S17 and step S19, charging current is decreased or increased with predetermined amplitude every time.
As shown in figure 4, judging whether terminal is in use state in step S13, can specifically be realized by following steps：
S131, the power consumption electric current Ic for obtaining terminal.
It is alternatively possible to suspend, charging is primary, the output current of battery is obtained during suspending charging, because working as charger
Pause charging after, then terminal is powered by battery, thus at this time battery output current that is, terminal power consumption electricity
Stream, therefore using the output current of the battery of acquisition as the power consumption electric current Ic of terminal.
Preferably, charging can be suspended at least twice, the output current of battery is obtained during each pause charging, is obtained altogether
At least two output currents are taken, calculate average output current accordingly, using the average output current of battery as the power consumption of terminal
Electric current Ic.
For example, it (such as 5 seconds) pause can charge once, suspend M times altogether, every time pause about 2 seconds at regular intervals,
And the output current of battery is obtained during each pause charging：I1, I2 ... Im, then calculate average output current Iv=(I1+I2
+ ...+Im)/M, using Iv as the power consumption electric current Ic of terminal.
In certain embodiments, can also direct detection terminal power consumption electric current, it includes resistance, inspection to need to add one at this time
The detection circuit that the hardware such as device are constituted is surveyed, the power consumption electric current for obtaining terminal is directly detected by detection circuit.
In addition it is also possible to obtain the power consumption electric current of terminal by other detection modes in the prior art, herein no longer
It repeats.
S132, the size for comparing power consumption electric current Ic and critical current Is, judge whether power consumption electric current Ic is more than critical current
Is.Work as Ic>When Is, step S133 is executed；As Ic≤Is, step S134 is executed.
S133, judgement terminal are in use state.
Critical current Is is preset current value, when the current power consumption electric current Ic of terminal is more than critical current Is, is then sentenced
Determine terminal and be currently at use state, is i.e. mobile terminal is being currently used in user.
S134, judgement terminal are in non-working condition.
When the current power consumption electric current Ic of terminal is less than or equal to critical current Is, then judge that terminal is currently at non-use
State, i.e. user are currently without using mobile terminal.
Judge that terminal, can also be in the following manner currently whether other than the use state except through power consumption electric current
