Can, there is provided common charge function, it is pressure limiting constant current to control charging modes, and its function includes：
First, heat limits protection
When charging temperature is too high, charging chip U2 automatically adjusts charging current, and the temperature of charging chip U2 typically has one
Individual maximum, such as 150 DEG C, when charging current is in the range of the maximum charging current for arranging, can be with charging chip U2 temperature certainly
Dynamic to adjust, such as more than 100 DEG C, electric current reduces, into the state of constant-voltage charge.
Its charging modes is generally divided into trickle, constant current, three kinds of constant pressure, when the voltage of battery U4 is less than setting value Vmin(such as
Trickle is carried out when 3V), the voltage of battery U4 rises to VminWhen (such as 3V), switch to constant current IconstCharge, reach agreement voltage
VconstSwitch to constant-voltage charge when (such as 4.2V), holding voltage is Vconst(such as 4.2V), when charging current is less than judgment threshold (
As be Iconst10% or so, it is adjustable), indicator lamp output low level, indicate battery U4 charging completes.
2nd, overvoltage protection
When battery U4 builtin voltages are excessive, can automatically generate shut-off voltage mode it is without damage to ensure charger, such as
Fruit VDCINLess than UVAT, then charger also remains in charging abnormal patterns, carries out voltage lockout, internal circuitry senses entry ISET
Pin current potential, if non-essential resistance vacantly causes VISETMore than VMSD, will be into shutdown mode.
Load device U1 can directly set up or disconnect the connection between charger 210 and battery U4 so that charging current from
Charger 210 directly reaches battery U4, and needs not move through charging chip U2, there is provided low-pressure direct fills function.
So-called low-pressure direct fills, and refers to and directly battery is charged using voltage difference, will the transmission of electricity pressure of charger be adjusted to
Slightly above the voltage of battery, the electric current obtained divided by impedance using voltage difference, carry out the direct charging to battery.
Additionally, load device U1 can also provide the functions such as impedance regulation.

Deng the embodiment of the present invention is not any limitation as to this.
In implementing, there is a register in the chip of the power supply of mobile terminal, when inserting or extract charging
During device, the change of a level signal can be produced, and then produce an interruption, in the interruption, can by reading the register
To judge being that insertion or extracts charger at charger.
In one embodiment of the invention, after step 101, can also judge that with mobile terminal whether charger is
It is supporting.If so, then by charger by the load device connection battery, to fill to battery according to default charging current
Electricity.If it is not, then execution step 102.
In implementing, the interface of mobile terminal configures a pin, and the USB ID pins of such as TpyeC are mobile whole
When terminating into standard configuration charger, the pin is pulled low, and when mobile terminal accesses non-standard charger, the pin is hanging.
When mobile terminal inserts charger, can pass through the state of the reading pin carries out judging that whether the charger is
The charger of standard configuration.
If the charger is the charger of standard configuration, low-pressure direct can be carried out according to the current versus cell of regulation and filled.
If the charger is the charger of non-standard configuration, battery can commonly be charged.
Step 102, by the charger by the charging chip to the battery, with default first initial current value
It is charged.
In implementing, charger and battery can be connected by charging chip, battery is commonly charged.
For the charger of non-standard configuration, one can be write than relatively low electric current in the register of certain in charging chip
Value, charging chip can adjust the impedance of itself, charging current is adjusted to the current value, commonly be charged.
In one embodiment of the invention, after step 102, fill to carry out low-pressure direct, can be examined as follows
Survey：
1st, support detection is directly filled
In here detection, can detect whether the charger that mobile terminal is accessed is supported directly to fill.
If support is directly filled, it is determined that charger is supported to be charged battery by loading device.
If not supporting directly to fill, continue common charging.
In implementing, can detect whether the charger is supported directly to fill charge protocol, then can determine the charger
Whether support directly to fill.
If the charger is supported directly to fill charge protocol, the charger is supported directly to fill, conversely, the charger is not supported directly
Charge protocol is filled, then can determine that the charger is not supported directly to fill.
It should be noted that directly fill charge protocol for different, such as QuickCharge, VOOC, Pump Express,
TI MaxCharge etc., with the different detection methods for directly filling charge protocol, for example, for QuickCharge, Ke Yixiang
Charger sends the voltage for specifying waveform, if the charger feeds back the voltage of another specified waveform, the charger is supported
QuickCharge, otherwise, the charger does not support that QuickCharge, the embodiment of the present invention are not any limitation as to this.
2nd, condition detection is directly filled
In here detection, current charging environment can be detected, it is determined that currently meet default directly filling condition.
Wherein, condition is directly filled including following one or more：
Charger adjustable output voltage, charging are in constant-current phase, battery temperature within the scope of default temperature.
For whether charger can adjust output voltage, can detect whether the charger supports adjustable output voltage
Directly fill charge protocol, if the charger support adjustable output voltage directly fill charge protocol, such as QuickCharge, then
The charger adjustable output voltage, conversely, the unadjustable output voltage of the charger.
Constant-current phase is in for charging, can be by detecting that the voltage of battery is judged, typically in 3.5V to 4.2V
Between, can be considered as in constant-current phase.
If battery temperature is within the scope of default temperature, represent that voltage temperature is normal, performance is relatively stable, conversely, table
Show that voltage temperature is higher, performance is more unstable.
Certainly, the above-mentioned directly condition of filling is intended only as example, when the embodiment of the present invention is implemented, can be set according to actual conditions
Put other and directly fill condition, the embodiment of the present invention is not any limitation as to this.In addition, except it is above-mentioned directly fill condition in addition to, art technology
Personnel can also directly fill condition using other according to actual needs, and the embodiment of the present invention is not also any limitation as to this.
Step 103, first object current value is increased in the charging chip by first initial current value, so that
The mobile terminal and/or the charger reach specified charging performance.

In embodiments of the present invention, a preliminary charging current (i.e. first initial electricity can be set in charging chip
Flow valuve, such as 1A), then at interval of the regular hour, control charging chip improves charging current, meanwhile, detection charger is current
Output voltage.
Because the power output of charger is fixed, therefore, when charging current increases, output voltage can gradually drop
It is low.
When the rated output ability of charger is reached, output voltage has one and more significantly declines.
Now, continue to increase charging current, when output voltage is less than fixed threshold value, it is believed that reached
The maximum output ability of the charger, records current charging current Ib.
In another embodiment of the present invention, step 103 can also include following sub-step：
Sub-step S15, on the basis of the first object current value the second current differential is deducted, used as the first new mesh
