In the case that the load at end matches, by prejudging whether demand voltage meets condition, it is defeated charger can be prevented
The case where voltage and current out is excessively high, and charger is avoided to overload is capable of providing the safety that mobile terminal charges.
Referring to Fig. 2, a kind of step flow chart of charging method of the embodiment of the present invention is shown, can specifically include as follows
Step:
Step 201, cell voltage and demand current are obtained.
Wherein, which is the voltage at the battery both ends of mobile terminal, which is negative with mobile terminal
The electric current to match is carried, for the battery charging for mobile terminal, and is the load supplying of mobile terminal.
During the charging process, mobile terminal may open different application programs in different time, cause mobile terminal
Required electric current changes, so that different electric currents be needed to charge.Therefore, for the safety of mobile terminal charging
Property, the electricity at mobile terminal battery both ends of the available current desired demand current wanted and mobile terminal during the charging process
Cell voltage, to determine demand voltage according to the cell voltage and demand current in the next steps.
Optionally, mobile terminal can acquire cell voltage by analog-digital converter ADC, and according to the negative of mobile terminal
It carries, determines demand current.
Specifically, during the charging process, when the number for the application program opened when mobile terminal changes, then mobile whole
The load at end changes, and mobile terminal can determine current desired electric current according to load.Moreover, in order to not influence charging
The safety of journey then can may also occur for the size of current that battery charges when the load of mobile terminal changes
Variation, therefore also needs to obtain the cell voltage at the battery both ends of mobile terminal, and so as in the next steps, mobile terminal can be with
It is calculated according to cell voltage and demand current.
Step 202, demand voltage is determined according to cell voltage and demand current.
Mobile terminal can be calculated according to pre-set formula, be obtained after obtaining cell voltage and demand current
To demand voltage, so that in the next steps, mobile terminal can control the voltage of charger output according to the demand voltage.
Specifically, since equivalent replace can be carried out to the circuit structure of mobile terminal, half pressure charging circuit and charger
It changes, obtains equivalent circuit, then it can be according to the equivalent circuit and the cell voltage and demand current of acquisition, according to equivalent with this
The corresponding demand voltage calculation formula of circuit is calculated, and the demand voltage that charger needs to export is calculated.
Wherein, which can be with are as follows:
Vbus=Iin*R+2Vbat+Iin*Req
Wherein, VbusFor demand voltage, IinFor demand current, R is equivalent impedance, VbatFor cell voltage, ReqIt is filled for half pressure
Electric circuit equivalent impedance, R and ReqIt can precalculate to obtain.
For example, referring to Fig. 3, Fig. 3 is equivalent circuit diagram corresponding with half pressure charging circuit, includes in the equivalent circuit diagram
The impedance R of charging cable first portcona, charging cable second port impedance Rcond, charging line impedence Rcable, protection circuit impedance
Rproc, the half equivalent impedance R for pressing charging circuiteq, battery adapter impedance RconbWith internal battery impedance Rbat.According to above-mentioned etc.
Circuit diagram is imitated, then can determine that demand voltage calculation formula can be with are as follows:
Vbus_adjust=Iin_adjust*(Rcona+Rcable+Rcond+Rproc)+2Vbat
+(Rconb+Rbat)*Iin_adjust+Req*Iin_adjust

Step 203, judge whether demand voltage meets regularization condition.
Mobile terminal is calculated after demand voltage, occurs situations such as charger overload in order to prevent, mobile terminal is also
It needs to judge demand voltage, to determine whether demand voltage meets regularization condition.When demand voltage meets regularization condition
When, then mobile terminal can control charger and is adjusted according to voltage of the demand voltage to output.
Moreover, charger when voltage is adjusted according to demand, need to carry out the voltage currently exported up-regulation or
It lowers.Therefore, mobile terminal can judge whether demand voltage meets voltage up-regulation condition and voltage lowers condition respectively.
It that is to say, regularization condition may include that voltage lowers condition and voltage up-regulation condition, and mobile terminal can first judge
Whether demand voltage, which meets voltage, is lowered condition, when demand voltage, which is discontented with afc voltage, lowers condition, then judges whether to meet electricity
Press up-regulation condition.Certainly, mobile terminal can also first judge whether demand voltage meets voltage up-regulation condition, again when being unsatisfactory for
Judge whether demand voltage meets voltage and lower condition, it is not limited in the embodiment of the present invention.
Therefore, step 203 may include step 203a and step 203b:
Step 203a obtains the half pressure input voltage and half pressure input current of half pressure charging circuit, according to half pressure input electricity
Size relation between size relation between stream and demand current, and half pressure input voltage and cell voltage, determines demand
Whether voltage, which meets voltage, is lowered condition.
Wherein, should partly pressure charging circuit pass through for connecting charger and mobile terminal, the voltage and current of charger output
Half pressure charging circuit is input to mobile terminal.
Specifically, mobile terminal can first obtain the half pressure input voltage and half pressure input current of half pressure charging circuit, and
According to the demand current and cell voltage obtained in step 201, whether half pressure input current of judgement is greater than demand current, and judges
Whether half pressure input voltage is greater than cell voltage, so that it is determined that whether demand voltage, which meets voltage, is lowered condition.
For example, mobile terminal may determine that half pressure input current whether be greater than demand current and adjust variable and value, and
Whether half pressure input voltage of judgement is greater than two times of cell voltage.When half pressure input current and half pressure input voltage are all satisfied correspondence
Condition when, then illustrate demand voltage meet voltage lower condition.Wherein, which can be used for adjusting charger output
Voltage or electric current.
Step 203b obtains the raw output voltage of charger output, according between half pressure input current and demand current
Size relation and raw output voltage and demand voltage between size relation, determine whether demand voltage meets voltage
Up-regulation condition.
This step 203b determines whether demand voltage meets the process of voltage up-regulation condition, determines demand electricity with step 203a
The process whether pressure meets voltage downward condition is similar, and details are not described herein.
But the Rule of judgment of this step 203b is different from the Rule of judgment of step 203a.For example, mobile terminal needs are sentenced
Whether disconnected half pressure input current is less than demand current and adjusts between variable and value, it is also necessary to whether judge raw output voltage
Less than demand voltage.
Step 204, when demand voltage meets regularization condition, the voltage that voltage exports charger according to demand is adjusted
It is whole.
When mobile terminal determines that demand voltage meets regularization condition, then adjustment instruction can be sent to charger, so that
Charger can be adjusted the voltage currently exported according to the adjustment instruction, so that the voltage of charger output is through more than half pressures
After charging circuit, voltage needed for the load of half voltage and mobile terminal for pressing charging circuit to export matches.
Further, corresponding with step 203a and step 203b citing, the available voltage adjustment of mobile terminal becomes
Amount, control charger adjust variable according to the voltage of acquisition and are adjusted to the voltage of output, prevent voltage change too fast, to shifting
Dynamic terminal causes to damage.It that is to say, mobile terminal can control charger and raise the voltage currently exported or be adjusted downward to certain
A parameter value.
Optionally, the available voltage of mobile terminal adjusts variable, adjusts the electricity that variable exports charger according to voltage
Pressure is adjusted, and voltage adjustment variable is used to indicate the variable quantity of adjustment demand voltage.
It should be noted that mobile terminal is it needs to be determined that whether demand voltage meets voltage downward item in step 203
Part, therefore in this step 204, when demand voltage, which meets voltage, lowers condition, mobile terminal can voltage pair according to demand
The voltage of charger output is lowered.In step 203b, mobile terminal is it needs to be determined that whether demand voltage meets on voltage
Tune condition, therefore in this step 204, when demand voltage meets voltage up-regulation condition, mobile terminal can be electric according to demand
The voltage exported to charger is pressed to raise.
Step 205, by preset duration, the voltage of charger output is adjusted again.
During the charging process for mobile terminal, charger output voltage and current can obtain always with it is current desired
The voltage and current wanted matches, and mobile terminal, which can recycle, obtains cell voltage and demand current, so as to again according to acquisition
Cell voltage and demand current are adjusted.
Optionally, by preset duration, the available cell voltage adjusted of mobile terminal and demand adjusted electricity
Stream, and according to cell voltage adjusted and demand current adjusted, the voltage of charger output is adjusted again.
Wherein, which can be spent according to the parameters in acquisition for mobile terminal step 201 to step 203
Time be determined, it is not limited in the embodiment of the present invention.
It should be noted that mobile terminal can constantly obtain the battery electricity of current desired demand current and battery both ends
Pressure, so can to charger export charging voltage be adjusted in time, enable charger output voltage in time with
Voltage needed for the load of mobile terminal matches.
In conclusion charging method provided in an embodiment of the present invention, the voltage for pressing charging circuit output half and movement are eventually
In the case that the load at end matches, by prejudging whether demand voltage meets condition, it is defeated charger can be prevented
The case where voltage and current out is excessively high, and charger is avoided to overload is capable of providing the safety that mobile terminal charges.
Further, condition or voltage downward item are raised by determining whether the demand voltage of mobile terminal meets voltage
Part, when demand voltage meets corresponding regularization condition, the voltage that mobile terminal can export charger is adjusted, and is avoided
In the case where demand voltage does not meet regularization condition, the voltage of charger output is adjusted, charger is caused to overload
The problems such as generation, improve mobile terminal charging safety.
Further, variable is adjusted by obtaining voltage, and the voltage that variable exports charger is adjusted according to the voltage
It is adjusted, great variety occurs in a short time for the voltage that can be exported to avoid charger, prevents from causing to damage to mobile terminal
Wound, improves the reliability of mobile terminal charging process.
Further, by obtaining cell voltage and demand current again, and according to the cell voltage of acquisition and demand electricity
