Embodiment
For making object of the present invention, technical scheme and advantage clearer, clear and definite, referring to accompanying drawing, developing simultaneously, the present invention is described in more detail for embodiment.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Refer to Fig. 1, Fig. 1 is the flow chart of the preferred embodiment of a kind of mobile terminal precharge of the present invention method of flow control.Mobile terminal precharge method of flow control shown in Fig. 1, comprises the following steps:
When step S100, the charging of mobile terminal connecting charger, whether mobile terminal detects in real time charger and disconnects; When mobile terminal detects charger, disconnect, obtain the instant preliminary filling current signal before charger disconnects;
In the embodiment of the present invention, while being mainly used in mobile terminal connecting charger employing large current charge, whether mobile terminal detects in real time charger and disconnects; When mobile terminal detects charger, do not disconnect, control and continue charging.First detect preliminary filling electric current, if this mobile terminal allows large precharge current charge, when not there is mobile phone disengaging charging device, continue charging.
If there is mobile phone, depart from charging device, need precharge stream to process, when mobile terminal detects charger, disconnect, obtain the instant preliminary filling current signal before charger disconnects.
Step S200, when mobile terminal connecting charger when charging again, judge whether the described instant preliminary filling current signal value before charger disconnects surpasses a predetermined value, when being converts described instant preliminary filling current signal to voltage signal, and the voltage signal after conversion is carried out to voltage stabilizing processing and step-down processing.
In the embodiment of the present invention, be that quick charger adopts large pre-charge, described instant preliminary filling current signal value before its charger disconnects is to be preliminary filling large current charge (be the charging current of quick charger, can in 1～5h, make storage battery reach or approach a kind of charging method of complete charged state).
In the present invention, described predetermined value be 900mA to 1.2A, mobile phone large current charge is generally that scope is: 900mA is to 1.2A.
Judge instant preliminary filling current signal value whether at above-mentioned 900mA within the scope of 1.2A, when being converts described instant preliminary filling current signal to voltage signal, and the voltage signal after conversion is carried out to voltage stabilizing processing and step-down is processed.For example, when processing preliminary filling electric current, with electric current voltage transformation module, convert described instant preliminary filling current signal (large preliminary filling electric current) to voltage signal; This voltage signal is carried out to voltage stabilizing processing; Due to the voltage signal after voltage stabilizing processing or the voltage signal of changing in large precharge current charge situation, need that this voltage signal is done to step-down and process.For example by reduction voltage circuit, process, voltage signal step-down is arrived to 3.5V at 3.3V.
Step S300, convert the voltage signal after voltage stabilizing processing and step-down are processed to new current signal, with the new current signal of this conversion, to mobile terminal, carry out precharge.
