Shown, the step S10 includes：
S110, whether detection mobile terminal has charger access at regular intervals.
S120, after having detected charger access, obtain the D+ ends and D- ends of the charger interface of mobile terminal access
Identification signal, and judge whether the charger is standard charger according to the identification signal.In other words, charger connects
The D+ ends of mouth and the identification signal at D- ends match with the default identification signal of mobile terminal, then charger is standard charger, no
It is then non-standard charger.In the present embodiment, the interface of the charger is USB interface, and USB interface includes Vbus terminals (electricity
Source voltage terminal), D+ terminals (data positive signal terminal), D- ends (data minus signal terminal) and GND terminal.
S20, supply voltage detecting step：
S210, detect charger be non-standard charger after, the charging current of mobile terminal is arranged to first and filled
Electric current.
S220, detect charger be standard charger after, the charging current is arranged to the second charging current.The
One charging current and the second charging current can be pre-set, and the first charging current is used to charge for non-standard charger, its electricity
Flow valuve is less than the second charging current for standard charger charging；Mobile terminal is charged using non-standard charger with reducing
Caused by damage risk.
Whether S230, the supply voltage (Vbus voltages) of detection charger output are more than predeterminated voltage.The predeterminated voltage
It can as needed be configured, such as may be configured as 4.9V.The effect of detection supply voltage size is：If greater than default electricity
Pressure then illustrates that the fan-out capability of charger is more than present charging current, and charger output potentiality are not brought into play, you can
Can be because charger type detection mistake causes the charging current of mobile terminal setting too small, if supply voltage is less than default
Voltage, illustrate that the charger fan-out capability is limited, it is impossible to support again high charging current, need not now detect charger class again
Type, without raising charging current.
S30, circulation step：
If the supply voltage of S310, charger output is more than predeterminated voltage, the charger detecting step S120 is judged
Whether the number of execution exceedes preset times N；If it is not, then enter step S320；If then terminating flow (does not return to charger inspection
Survey step S120).The preset times N can be configured according to the actual requirements, for example, 5 times, it is 10 inferior；Number is more, to filling
The detection of appliance type is more accurate.
S320, delay preset time, return to the charger detecting step S120.The preset time can be according to reality
Demand is configured, such as can be chosen in 1s between 1min.
It can be seen that in the present embodiment, if Vbus voltages are more than predeterminated voltage, charger is detected again after a period of time that is delayed
Type, if testing result is still nonstandard charger, then detects charger type again after a period of time that is delayed, so circulate past
It is multiple, terminate when charger type is detected as standard charger, or terminate after detection charger type n times.The present embodiment
The detection that is delayed again after the fan-out capability for first judging charger is taken, repeated multiple times detection is reduced to wait D+D- linear contact lays stable
The probability of charger detection error, improves the accuracy of charger detection, and then improve charge efficiency.

Fruit is exported to charging current setup module 20 and supply voltage detection module 30.The standard charger is to be adapted to mobile terminal
Charger, it is then non-standard charger not to be adapted to mobile terminal.Specifically, the charger detection module 10 is every certain
Whether time detecting mobile terminal has charger access；When there is charger access, the charger for obtaining mobile terminal access connects
The D+ ends of mouth and the identification signal at D- ends, and judge whether the charger is standard charger according to the identification signal.
In other words, the D+ ends of charger interface and the identification signal at D- ends match with the default identification signal of mobile terminal, then charge
Device is standard charger, is otherwise non-standard charger.In the present embodiment, the interface of the charger is USB interface, and USB connects
Mouth includes Vbus terminals (power supply voltage terminal), D+ terminals (data positive signal terminal), D- ends (data minus signal terminal) and GND
Terminal.
Charging current setup module 20, for detecting that the charger is non-standard charging in charger detection module 10
After device, charging current is arranged to the first charging current；Detect that charger is standard charger in charger detection module 10
Afterwards, charging current is arranged to the second charging current.First charging current and the second charging current can be pre-set, the first charging
Electric current is used to charge for non-standard charger, and its current value is less than the second charging current for standard charger charging；With
Reduce damage risk caused by being charged using non-standard charger to mobile terminal.
Supply voltage detection module 30, for detecting that the charger is non-standard charging in charger detection module 10
After device, whether the supply voltage of detection charger output is more than predeterminated voltage, and testing result is exported to processing module 40.Institute
Stating predeterminated voltage can be configured as needed, such as may be configured as 4.9V.
Processing module 40, the supply voltage for detecting charger output in supply voltage detection module 30 are more than default
After voltage, startup charger detection module 10 detects whether the charger is standard charger after preset time, so as to enter
Enter next charger detection circulation.
Further, the processing module 40 can built-in counter, for detecting charger to charger detection module 10
Whether it is that the number of standard charger is counted.The processing module 40 is specifically used for：Examined in supply voltage detection module 30
The supply voltage of charger output is measured more than the number for after predeterminated voltage, judging the charger detection module detection charger
Whether exceed preset times, if it is not, then start after preset time charger detection module 10 detect the charger whether be
Standard charger, detect and circulate hence into next charger.
It can be seen that in the present embodiment, if Vbus voltages are more than predeterminated voltage, charger is detected again after a period of time that is delayed
Type, if testing result is still nonstandard charger, then detects charger type again after a period of time that is delayed, so circulate past
It is multiple, terminate when charger type is detected as standard charger, or terminate after detection charger type n times.The present embodiment
The detection that is delayed again after the fan-out capability for first judging charger is taken, repeated multiple times detection is reduced to wait D+D- linear contact lays stable
The probability of charger detection error, improves the accuracy of charger detection, and then improve charge efficiency.
