Referring to shown in Fig. 3, one embodiment of charge protection method includes: in the embodiment of the present invention
101, when terminal detects charged state exception, terminal sends the first protection instruction to charging protector, described
First protection instruction is used to indicate the charging protector starting charge protector.
When terminal is charged by power supply adaptor or other charging equipments, terminal real-time detection charged state,
The charged state includes the voltage and current state of charging and the use state and operating status of terminal inner.When terminal is examined
When measuring charged state exception, then the first protection instruction is sent to charging protector at once.
In one possible implementation, the battery of terminal is abnormal or whole when charged state may include charging extremely
The operating status at end is abnormal, for example, cell voltage is higher than third predetermined threshold value;Alternatively, battery current is higher than the 4th preset threshold;
Alternatively, terminal temperature is higher than the 5th preset threshold.
In general, charging includes fast charge mode and trickle charge mode, the charging voltage and charging current of fast charge mode are all larger than
Trickle charge mode, the charging voltage of fast charge are generally 4.2V or so, and charging current is 2A or so.Due to the office of terminal hardware technology
Limit, the current unbearable biggish voltage and current of the battery of terminal.If the cell voltage of terminal is excessively high or battery current
It is excessively high, then the battery of terminal can be damaged.Therefore, the voltage of battery and electric current are no more than certain when charging can be set
Threshold value, for example, voltage, no more than 4.5V, electric current is no more than 2.5A, if being more than, then it represents that charged state is abnormal.It needs
Bright, which can set according to the ability to bear of the battery of terminal, if the ability to bear of the battery of terminal compared with
High the preset threshold can be then arranged higher.In addition, it is abnormal that charging can also be considered as when the temperature of terminal is higher.Eventually
End can also the temperature of real-time detection to the battery temperature of terminal and the processor of terminal can when the temperature of battery is higher
Can cause the danger of explosion may then damage the hardware of terminal when the temperature of processor of terminal is higher.Therefore to end
The battery temperature and temperature of processor at end are respectively provided with a threshold value, such as when battery temperature is more than 60 °, then it represents that charged state
It is abnormal, when the temperature of processor of terminal is more than 70 °, then it represents that charged state is abnormal.
Optionally, terminal can also further detect whether the operating status of terminal, such as terminal are in highly energy-consuming trip
Whether play state or terminal are on call, since highly energy-consuming game and call are the processing that can result in terminal
The excessively high reason of device temperature therefore, can also as long as terminal detects terminal processes highly energy-consuming game state or talking state
To be considered as charged state exception.
In alternatively possible implementation, the charging abnormality can also be abnormal for charger charging.
Because terminal is typically equipped with the charger of oneself, such as fast charge adapter, fast charge adapter be also use or " D+,
D- " data-interface checks the fast charge request of terminal, negotiates to charge with terminal.And the charging protector in the embodiment of the present invention is being set
It is " transparent " to the communication of fast charge adapter and terminal on meter.If quick charge adapter has monitoring terminal signaling in turn
The charge protection taken can also use charging protector as the redundancy scheme or enhancing mechanism of charging safety.Therefore, in this hair
In bright embodiment, whether the work that terminal can also monitor fast charge adapter is abnormal, if abnormal, can enable redundancy scheme,
Protection instruction is sent to charging protector, to carry out stand-by protection.
102, charging protector receives the first protection instruction that terminal is sent.
Communication unit is provided in charging protector, so that " D+, D- " data-interface and terminal are established by such as above-mentioned
Communication connection, and the instruction that receiving terminal is sent.The first protection instruction can be an open signal, for example be WA_ON letter
Number.
103, charging protector is according to the first protection instruction starting charge protector.
After charging protector receives the first protection instruction of terminal transmission, then start charging protection mechanism, in this hair
It is that charge protection is carried out by charge protector set in charging protector in bright embodiment.Specifically, the charging
Protection circuit can connect on the interface of charging cable, control charger to the electricity of terminal by increasing the elements such as resistance and capacitor
Pressure and electric current output.
104, charging protector controls charging voltage less than the first preset threshold and/or control by the charge protector
Charging current processed is less than the second preset threshold.
When terminal is charged, any charging exception no matter occurs, by control charging voltage and can generally fill
The output of electric current, so that the charging for solving terminal is abnormal.Such as terminal cell voltage is excessively high or the battery current of terminal
Excessive, then voltage when can be charged by charge protection current control charger is less than certain threshold value, and/or, control charging
Electric current be less than certain threshold value.To achieve the purpose that reduce the voltage of end cell and the battery current of terminal.For another example, eventually
The temperature at end is excessively high, if charger still uses higher charging voltage and charging current, may cause the constant temperature of terminal
It is maintained at a higher state, accordingly it is also possible in such a way that control charging voltage becomes smaller and becomes smaller with charging current, thus
Achieve the purpose that reduce terminal temperature.
Optionally, after charging protector opens charge protector, warning lamp or alarming sound is can be sent out, be used for
User is reminded to handle charge protection state at present.
In the present invention, charging protector first receives the first protection instruction of terminal transmission, and the first protection instruction is institute
It states terminal and detects the instruction issued when charged state exception, instruct starting charge protector further according to the protection, then
It is default less than second less than the first preset threshold and/or control charging current that charging voltage is controlled by the charge protector
Threshold value.In this way, charging protector and terminal establish communication connection, charged state when charging is detected by terminal, if discovery is different
Often, then protection instruction is sent to charging protector, so that charging protector passes through protection circuit control charging voltage and charging electricity
Stream carries out charge protection to terminal to realize.
Referring to shown in Fig. 4, another embodiment of charge protection method includes: in the embodiment of the present invention

205, when terminal detects that duration of charged state exception is more than preset duration, terminal is to the charger
Device transmission the second protection instruction is protected, the second protection instruction is used to indicate the charging protector disconnection charger and fills for terminal
The route of electricity.
In Fig. 3 embodiment, when terminal detects charged state exception, charging protector is simply by charge protector
Charging voltage and/or charging current are reduced, in practical applications, the charging that still possibly can not solve terminal is abnormal, such as
Terminal runs highly energy-consuming game and causes the temperature of terminal excessively high in charging, passes through charging protector in time for charging voltage
It is reduced with charging current, can not still alleviate the temperature of terminal, and if so continuing longer time, it still can be to terminal
Hardware damages, therefore terminal can be charged the duration of abnormality with real-time detection, for example work as Abnormal lasting
When more than 30 minutes, terminal then sends the second protection instruction to charging protector, and it is eventually that instruction charging protector, which disconnects charger,
The route for holding charging, stops as terminal charge.
206, charging protector receives the second protection instruction that the terminal is sent.
207, charging protector disconnects the route that charger is the terminal charge by the charge protector.
Specifically, the modes such as circuit switch can be set in charge protector turns off the charger line for terminal charge
Road, so that achieving the purpose that stop is terminal charge.
208, when terminal detects that charged state restores normal, terminal sends protection revocation to the charging protector and refers to
It enables, the protection cancel an order is used to indicate the charging protector and closes the charge protector.
Optionally, it when the charged state of terminal restores normal, then no longer needs to continue to use charging protector and charge
Protection, terminal can then send protection cancel an order to charging protector, restore normal charging condition.For example, when charging, user
After no longer passing through terminal operating highly energy-consuming game, then the temperature of terminal will lower naturally, so that the charging of terminal
State restores normal.
209, charging protector receives the protection cancel an order that the terminal is sent.
210, charging protector closes the charge protector according to the protection cancel an order, so that charger is institute
It states terminal charge and restores normal.
After charging protector receives the protection cancel an order of terminal transmission, then charge protector is closed, to make
Charging protector is obtained for being " transparent " between charger and terminal, then charger can then be restored to original charging ginseng
Several pairs of terminals charge.
In the embodiment of the present invention, when terminal detects that the duration of charged state exception is more than preset duration, terminal
The second protection instruction is sent to the charging protector, indicates that the charging protector disconnects the line that charger is terminal charge
Road.In this way, further carried out charge protection to terminal, reduce damage caused by terminal persistently charges after exception.In addition,
When terminal detects that charged state restores normal, terminal is sent to the charging protector protects cancel an order, described in instruction
Charging protector closes the charge protector.In this way, terminal can then be restored to the charging of normal parameter, to improve use
Family experience.
Referring to Figure 5, one embodiment of charging protector includes: in the embodiment of the present invention
