The size of S12, C.T T and the first critical temperature Tn, judges whether temperature T is greater than the first critical temperature Tn.As T>Tn, perform step S13; As T≤Tn, perform step S15.
Wherein, the first critical temperature Tn is default temperature value.
S13, judge whether terminal is in using state.When terminal is in using state, perform step S14; When terminal is in non-working condition, perform step S15.
Wherein, whether terminal is in the concrete determination methods of using state, will be described in detail later.
S14, maximum temperature Ts is set equals the first critical temperature Tn.
Wherein, the Limit temperature value that battery reaches is allowed when maximum temperature Ts is charging.When battery temperature T is greater than the first critical temperature Tn and terminal is in using state, then Ts=Tn is set.
S15, maximum temperature Ts is set equals the second critical temperature Tm.
Wherein, the second critical temperature Tm is another default temperature value, and Tm>Tn.When battery temperature T is less than or equal to the first critical temperature Tn, or when battery temperature T is greater than the first critical temperature Tn and terminal is in non-working condition, then Ts=Tm is set.
The size of S16, C.T T and maximum temperature Ts, judges whether T is greater than Ts.As T>Ts, perform step S17; When T is not more than Ts, perform step S18.
S17, reduction charging current.
In this step S17, when battery temperature T is greater than maximum temperature Ts, illustrate that current battery temperature is too high, exceeded Limit temperature value during battery charging, therefore reduced charging current, prevent terminal overheated.
S18, judge whether T is less than Ts-K.As T<Ts-K, perform step S19, otherwise process ends.
Wherein, K is default constant, K >=0, and concrete size can set according to actual needs.
S19, increase charging current.

Im, calculate average output current Iv=(I1+I2+ again ... + Im)/M, using the power consumption electric current I c of Iv as terminal.
In certain embodiments, also can the power consumption electric current of direct-detection terminal, now need to set up one and comprise the testing circuit that the hardware such as resistance, checkout gear forms, carry out by testing circuit the power consumption electric current that direct-detection obtains terminal.
In addition, also can be obtained the power consumption electric current of terminal by other detection mode of the prior art, not repeat them here.
S132, compare the size of power consumption electric current I c and critical current Is, judge whether power consumption electric current I c is greater than critical current Is.As Ic>Is, perform step S133; As Ic≤Is, perform step S134.
S133, judgement terminal are in using state.
