Step S2031, when the terminal operating status for receiving the mobile terminal return are holding state, the electricity
When pond electricity reaches the first preset temperature more than maximum temperature value in default electricity, and the temperature value of the sampling acquisition, reduce
The charging current of the adapter output.
Such as, by taking mobile phone as an example, the default electricity is the 40% of battery capacity, and first preset temperature is 50 DEG C.
When receive mobile phone return terminal operating status be holding state, and the battery electric quantity more than battery capacity 40% when,
User's normally using within a period of time is can ensure that, such as can ensure that the use time of 4 hours of user.But adaptation
The temperature value of each pyrotoxin can be variant in device, and some heating source temperatures are high, and some heating source temperatures are low, but once certain
The temperature value of pyrotoxin is too high, when reaching a certain threshold value, may influence whether the performance of adapter.Therefore, when the sampling is obtained
When maximum temperature value reaches the first preset temperature in the temperature value for obtaining, can be according to preset temperature range and preset charged electric current

The charging current of the adapter currently output is held, to ensure normally using for mobile phone.But, when temperature is too high, easily burn out
Adapter, then when maximum temperature value reaches the second preset temperature in the temperature value that the sampling is obtained, can be according to default temperature
Degree scope reduces the charging current of the adapter output, such as filling original 4.5A with the corresponding relation of preset charged electric current
Electric current is adjusted to 1A and is exported, and to reduce the heating of multiple pyrotoxins in adapter, makes the multiple pyrotoxins in adapter
Slowly lower the temperature after a period of time, make adapter be damaged to prevent temperature too high.
Step S2033, when the terminal operating status for receiving the mobile terminal return are holding state, the electricity
When pond electricity reaches the second preset temperature less than maximum temperature value in default electricity, and the temperature value of the sampling acquisition, reduce
The charging current of the adapter output.
For example, such as, by taking mobile phone as an example, the default electricity is the 40% of battery capacity, and first preset temperature is
50 DEG C, second preset temperature is 60 DEG C.When the terminal operating status for receiving mobile phone return are holding state, and the electricity
When pond electricity is less than the 40% of battery capacity, and maximum temperature value reaches the second preset temperature in the temperature value of the sampling acquisition
When, the charging current of adapter is not adjusted, it is to maintain the charging current of the adapter currently output, such as described defeated
The charging current for going out is 4.5A, to ensure at short notice as much as possible to charging mobile phone battery, to meet user to being filled
The mobile phone of electricity is filled with as far as possible the demand of more electricity in the short time.But when maximum temperature in the temperature value that the sampling is obtained
When value reaches the second preset temperature, described adaptation can be reduced with the corresponding relation of preset charged electric current according to preset temperature range
The charging current of device output, such as be adjusted to the charging current of original 4.5A 1A and exported, multiple in adapter to reduce
The heating of pyrotoxin, makes the multiple pyrotoxins in adapter slowly lower the temperature after a period of time, to prevent adapter temperature mistake
Hardware performance that is high and affecting adapter.
Step S204, determines the adapter and exception occurs by detecting current charging current and current charging voltage
Reason, and by it is described occur abnormal the reason for send to mobile terminal.
It is understood that by it is described occur abnormal the reason for send to mobile terminal, make user know adapter in time
The reason for occurring abnormal, as user the reference frame of the scheme of remedying is taken.
It is zero when the current charging current is detected in some embodiments, and the current charging voltage is specified
During voltage, determine that short circuit occurs in the adapter.
In some embodiments, it is not zero when the current charging current is detected, and the current charging voltage is volume
When determining voltage, determine that the charging current of the adapter is unstable.
Step S205, disconnects the path of the adapter and alternating current.
Can it is also to be understood that, when adapter internal heat generation source temperature change state for be rapidly heated state when, judge described
There is exception in adapter, the path for disconnecting the adapter and alternating current is now needed, to prevent external alternating current excessive
And burn out adapter.
