Description of drawings
Fig. 1 is the charging circuit structure chart of the portable terminal of prior art;
The flow chart of the portable terminal charge protection method that Fig. 2 provides for the embodiment of the invention;
The structure chart of the portable terminal charge protection device that Fig. 3 provides for the embodiment of the invention.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the present invention, and be not used in restriction the present invention.
Fig. 2 shows the flow process of the portable terminal charge protection method that the embodiment of the invention provides.
In step S201, a charge threshold and storage are set;
In specific implementation process, described charge threshold is arranged one fixedly ID number, described charge threshold is communicated with described ID number storage.
In step S202, when detecting charger and charge for described portable terminal, the charging interval is carried out timing;
Wherein, portable terminal starts a software timer, and this timer is set a timing variable and is initialized as 0, and every mistake kind timing in second variable just adds 1 second, and so, this software timer just can be noted down the time of thrusting after charger inserts.
In step S203, judge whether the charging interval reach the charge threshold of setting, if carry out step S204; Otherwise proceed this determining step.
In step S204, then cut off being connected of described charger and portable terminal, stop charging;
This step specifically comprises: at first allow software withdraw from the charged state machine, to guarantee that portable terminal can not enter " again towards electric process " again, control the CHG_CTL pin (seeing also Fig. 1) of triode PNP in the charging circuit afterwards by the interface of software, to disconnect the triode PNP that connects charger, namely disconnect the supply path of charger, so just stopped charging and power supply, can't enter " recharging process " again.
Wherein, if described charge threshold is zero, expression does not need the charge protection function, just can not start the charge protection timer yet, and by the program of charging normal described portable terminal being charged gets final product.
The embodiment of the invention is by arranging charge threshold; on the basis of original charging circuit; mode by software has realized the regularly function of charge protection; can be by mobile phone setting time of long charge threshold; for example 12 hours; 24 hours or 36 hours; after the charging interval reaches the longest charge threshold; software can be controlled being connected of charger automatic disconnection and mobile phone, stops to cell-phone charging and power supply, then; As time goes on; mobile phone voltage can reduce, even but the voltage of mobile phone is lower than the voltage threshold that recharges, can not continue charging to mobile phone yet.Thereby reached the effect of protection mobile phone and battery.
