The schematic flow sheet of a kind of method regulating charging current that Fig. 1 provides for the embodiment of the present invention one.The method bag
Include step S101～S104.
S101, if be charged terminal, obtains the first constant-voltage charge electric current and the second constant-voltage charge electric current of terminal.
Concrete, in embodiments of the present invention, it is charged terminal referring to use charging device terminal to be charged, accurately
Saying, connecting charging device by charging data line and be charged with terminal, described terminal includes but not limited to mobile phone, flat board electricity
Brain；When terminal is charged by charging device, charging process can be divided into four-stage, including trickle charge, constant-current charge,
Constant-voltage charge and charging termination, wherein, constant-voltage charge refers to when terminal battery voltage rises to a certain setting voltage value,
Constant-current charging phase terminates, and starts constant voltage charging phase, and now the output voltage of charging device keeps constant, described first constant voltage
The charging current that charging current, the second constant-voltage charge electric current are in constant voltage charging phase, more precisely, user can obtain
Arbitrary two charging currents when constant voltage charging phase are as described first constant-voltage charge electric current, the second constant-voltage charge electric current.
S102, obtains the terminal the first input voltage when the first constant-voltage charge electric current and when the second constant-voltage charge electric current
The second input voltage.Concrete, in embodiments of the present invention, owing to described terminal is entered by charging device by charging data line
During row charging, differ with the voltage acted on described terminal, therefore, accordingly from the voltage of charging device output
Ground, when obtaining the first constant-voltage charge electric current, obtains the voltage acting in described terminal as described first input electricity simultaneously
Pressure, when obtaining the second constant-voltage charge electric current, obtains the voltage acting in described terminal as described second input electricity simultaneously
Pressure.
S103, according to the first constant-voltage charge electric current, the first input voltage and the second constant-voltage charge electric current, the second input voltage
The charging resistance value of computing terminal.Concrete, in embodiments of the present invention, owing to using charging device by charging data line pair
When described terminal is charged, all there is different size of impedance, and different filling in charging data line or described terminal itself
The conveyance capacity of electricity data wire is different, and the impedance that correspondence shows is the most different, and generally little the crossing of charge data line impedence is flowed
Ability is big, and the conveyance capacity that impedance is big is little, it is therefore desirable to computing terminal charging resistance value during being charged, and for
The maximum charging current of different charging resistance value regulation terminals.
S104, according to the maximum charging current of charging resistance value regulation terminal.
As seen from the above, when the embodiment of the present invention is by being charged terminal, obtain the first constant-voltage charge electric current and
Two constant-voltage charge electric currents and obtain the first input voltage, second defeated according to the first constant-voltage charge electric current, the second constant-voltage charge electric current
Enter voltage, and calculate according to the second constant-voltage charge electric current, the first constant-voltage charge electric current and the first input voltage, the second input voltage
Obtain the charging resistance value of described terminal, finally according to charging resistance value, the maximum charging current of described terminal be adjusted,
It is possible to prevent owing to the charging current of terminal is excessive, and when the charging impedance of charging data line or terminal itself is too high, charging
The accident that data wire or terminal are burnt because of excessive heating.
Further, in embodiments of the present invention, as in figure 2 it is shown, step S103, according to the first constant-voltage charge electric current,
One input voltage and the second constant-voltage charge electric current, the charging resistance value of the second input voltage computing terminal, specifically include step
S1031～S1033.
S1031, the difference calculating the first input voltage and the second input voltage obtains the first difference.Concrete, at this
In bright embodiment, we can arrange the first input voltage is V1, and the second input voltage is V2, then the first input voltage V1 with
The difference of the second input voltage V2 is V1-V2, and the most described first difference is V1-V2.
S1032, the difference calculating the second constant-voltage charge electric current and the first constant-voltage charge electric current obtains the second difference.Specifically
Hands, in embodiments of the present invention, we can arrange the first constant-voltage charge electric current is I1, and the second constant-voltage charge electric current is I2, that

I1。
S1033, the quotient calculating the first difference and the second difference obtains the resistance value that charges.Concrete, implement in the present invention
In example, we can arrange charging resistance value is R, then the first difference is V1-V2, the second difference is I2-I1, fixed according to ohm
Rule, described charging resistance value R=(V1-V2)/(I2-I1), say, that described first difference V1-V2 and described second difference
Quotient (V1-V2)/(I2-I1) of I2-I1 is described charging resistance value R.
As seen from the above, step S1031～S1033 in the embodiment of the present invention one, utilize the first difference and the second difference also
It is calculated charging resistance value according to Ohm's law, facilitates user to regulate the maximum charge electricity of described terminal according to charging resistance value
Stream.
Further, in embodiments of the present invention, as it is shown on figure 3, step S104, according to charging resistance value regulation terminal
Maximum charging current, specifically includes step S1041～S1042.
S1041, if charging resistance value is less than preset charged resistance value, regulates the maximum charging current of terminal to the first electricity
Flow valuve.Concrete, in this step, owing to the conveyance capacity of different charging data lines is different, be charged terminal
During, the charging resistance value showed also can be different, accordingly, it would be desirable to set described terminal according to different charging resistance values
Put different maximum charging currents, in embodiments of the present invention, it would be desirable in advance in terminal profile one charging resistance value, example
As this preset charged resistance value is set as 0.3 Ω, when the charging resistance value calculated is 0.1 Ω, corresponding regulation terminal
Maximum charging current is 5A, and when the charging resistance value calculated is 0.2 Ω, the maximum charging current of corresponding regulation terminal is
4A。
S1042, if charging resistance value is more than preset charged resistance value, regulates the maximum charging current of terminal to the second electricity
Flow valuve, described second current value is less than the first current value.Concrete, in this step, such as, set this preset charged resistance value
Being 0.3 Ω, when the charging resistance value calculated is 0.4 Ω, the maximum charging current of corresponding regulation terminal is 2A, works as calculating
When charging resistance value out is 0.5 Ω, the maximum charging current of corresponding regulation terminal is 1A, it should be noted that generally feelings
Under condition, the charging resistance value of charging data line is the least, and conveyance capacity is the biggest, and charging resistance value is the biggest, and conveyance capacity is the least.
As seen from the above, by regulating the pairs of maximum charging current values of described terminal according to calculated charging resistance value,
Be possible to prevent charging data line because of the maximum charging current of described terminal excessive time, because of charging data line excessive heating and burn and
Charging device and described terminal is caused to be damaged.

S204, according to the maximum charging current of charging resistance value regulation terminal.
S205, contrasts with threshold value set in advance according to charging resistance value.Concrete, in embodiments of the present invention,
If we use charging device and terminal itself to support bigger charging current, but owing to have selected conveyance capacity relatively
Little and bigger on charging process impact charging data line, such as, threshold value set in advance is 0.6 Ω, at charging resistance value
In the case of 0.6 Ω, when using this charging data line that described terminal is charged, because charging resistance value is excessive, thus
Add the charging interval of terminal, and bring bad experience to user simultaneously, further cause charging process to become not have
