Fig. 1 is a kind of method flow diagram for controlling mobile power source charge and discharge provided in an embodiment of the present invention.As shown in Figure 1,
Control mobile power source charge and discharge method include:
Whether step S110, detection mobile power source connect external power supply and mobile terminal simultaneously.
Step S120 controls mobile power source list when detecting that mobile power source only connects external power supply or mobile terminal
One carries out charge or discharge.
Step S130 passes through USB enumeration state when detecting mobile power source while connecting external power supply and mobile terminal
Further judge that external power supply is power supply adaptor or indirect power supply unit.
In this step, because being different from power supply adaptor, indirectly in mobile power source when connecting indirect power supply unit
The electric current that power supply unit provides usually requires to meet interface standard, and the size of current provided is limited.Judge the type of external power supply,
The electric current that can detect that external power supply provides has been whether size limitation.
Step S140, if judgement is power supply adaptor, control mobile power source carries out charge and discharge simultaneously.

Service life, for guarantee mobile power source battery capacity, rotation carry out charge and discharge when, be to the battery of mobile power source
Electricity carries out real-time monitoring, and sets low, high power threshold, once the battery capacity of mobile power source is lower than default low battery threshold value
When, mobile power source pause electric discharge need to be controlled, carries out charging until battery capacity, which is not less than, presets high power threshold, then controls
Mobile power source pause charging, discharges.Because the battery capacity to mobile power source is real-time detection, the low battery threshold of setting
Value is the standard for controlling mobile power source and whether carrying out preferential discharge, and discharging function is switched to charging function by control mobile power source
The standard of energy；The high power threshold of setting is the standard for controlling mobile power source and charge function being switched to discharging function；It sets simultaneously

In this process, because be the battery capacity of mobile power source is monitored in real time, once there is battery capacity
The case where lower than default low battery threshold value, will control mobile power source pause electric discharge, carry out charge function, guarantee mobile power source
Battery capacity is not less than charging to mobile terminal in the case where presetting high power threshold.So control mobile power source electric discharge
The case where being lower than default low battery threshold value if there is the battery capacity of mobile power source in the process is that rotation carries out charge and discharge in fact
Function, it until after the battery capacity of mobile terminal is full of, then controls mobile power source and is carried out continuously charging, until mobile power source
Electricity be full of, terminate entire program.
In one embodiment of the invention, it includes: to sentence that the control mobile power source in step S140, which carries out charge and discharge simultaneously,
Whether the battery capacity of disconnected mobile terminal is full of, and is that then, control mobile power source terminates to discharge；And while judging mobile power source
Battery capacity whether be full of, be then, control mobile power source terminate to charge.
Because be all control mobile power source while carrying out charging/discharging function, the control mobile power source in step S150 is same
Shi Jinhang charge and discharge also include: to judge whether the battery capacity of mobile terminal is full of, and are that then, control mobile power source terminates to discharge；
And judge whether the battery capacity of mobile power source is full of, it is that then, control mobile power source terminates to charge.
