Concrete accompanying drawing explanation
By reading the detailed description done non-limiting example with reference to the following drawings, the present invention and feature, profile and advantage will become more apparent.Mark identical in whole accompanying drawing indicates identical part.Proportionally can not draw accompanying drawing, focus on purport of the present invention is shown.
Fig. 1 is the structural representation of charging system in the embodiment of the present invention.
Embodiment
Core concept of the present invention is: adopt the power management chip with supercharging module with for the different power consumption scene of mobile terminal device, carry out the adjustment of dynamical output electric current.
Below in conjunction with accompanying drawing and specific embodiment, the present invention is further illustrated, but not as limiting to the invention.
For in traditional charging system, the huge power consumption applied because of game, video etc. causes the electric current flowing into battery very little, the charge efficiency of battery is affected, the defect such as charge rate, deterioration of efficiency, the invention provides a kind of charging system, and be described in detail as mobile terminal device using mobile phone.
Concrete, this charging system mainly includes detecting module, Optimization analyses module and power management chip.
Power management chip is located in charging module, and its model is PM8941, and wherein, this power management chip has output and control end, and this output is electrically connected with mobile phone, for charging to mobile phone.
The detecting unit that several are little is included in detecting module, such as mobile phone ON/OFF detecting unit, screen intensity detecting unit, call detecting unit, media detecting unit, network detecting unit and/or current sense unit, the detecting module that above-mentioned detecting unit is formed is connected with mobile terminal device-mobile phone, to obtain the service data of mobile phone, as shown in Figure 1.
Because detecting module comprises several little detecting units, the service data therefore detected mainly includes: the charging current information of mobile phone power-on or off-mode information, screen intensity class information, call status information, media status information, network state information and mobile terminal device.Concrete, mobile phone open and close detecting unit is for detecting start or the off-mode of mobile phone, the brightness degree of screen intensity detecting unit detecting mobile phone screen, whether call detecting unit detecting user mobile phone is in talking state, whether media detecting unit is in video state for detecting user mobile phone, whether network detecting unit is in upper net state for detecting user mobile phone, and current sense unit is for detecting the size of the charging current of battery of mobile phone.Detecting module to detect each power consumption scene above-mentioned and charging current, and obtains the service data of different power consumption scene by each little detecting unit above-mentioned.
Optimization analyses module is connected with the control end of power management chip, detecting module respectively, accept the service data obtained from detecting module, and carry out the size of the output output current controlling power management chip according to the service data of this different power consumption scene.
Concrete, power management chip also includes a supercharging module (increasing the output voltage of power management chip) and register; After Optimization analyses module receives above-mentioned service data, whether start this supercharging module according to Operational Data Analysis, if start this supercharging module, the output continuing to analyze power management chip needs the size of the output current increased.Power management chip also includes register in addition, after startup supercharging module, the signal of the size of the output current that the output needs that register receives power management chip increase, then adjusts the output current of the output of power management chip, and then completes the adjustment to mobile phone charging.
Carry out being described this charging system with a scene below: optional but in nonrestrictive embodiment, suppose that mobile phone is in open state and is in running status one, and do one with the screen intensity grade in detecting module and network state and illustrate.The screen of mobile phone is adjusted to high-high brightness, many 250mA are wanted during the power consumption average specific mobile phone normal Standby of now mobile phone, if the now WIFI function of surfing the Net of starting hand-set, the power consumption of mobile phone will continue to increase 100mA, therefore these two kinds of power consumption scene can cause mobile phone than many power consumptions 350mA during normal Standby, therefore when charging to mobile phone, if the supercharging module not in power-on managing chip is to increase the output current of power management chip, the charging current of battery of mobile phone will decline 350mA, and then causes the charge efficiency of battery of mobile phone to reduce.But now this optimization module can judge the size (as needed to increase output current 200mA, 250mA or 300mA of power management chip) of the output current that the needs after needing the supercharging module of power-on managing chip and power-on managing chip increase according to the service data of two above-mentioned scenes, then finally complete electric current by charging module and adjust and then the charge efficiency of mobile phone is improved greatly.
If certainly mobile phone is in shutdown or holding state, mobile phone can charge normal, and after optimizing module analysis, can the supercharging module of powered-down managing chip to reduce the output current of power management chip, and then protection battery, the useful life of prolongation battery.
In sum, the invention discloses a kind of charging system, mainly comprise power management chip, detecting module and the Optimization analyses module with supercharging module, detecting module is for detecting service data when mobile terminal device charges, and control according to service data the size of current that power management chip exports after Optimization analyses module receives, and then complete the charging of mobile terminal device is adjusted; This technical scheme can carry out the output current realizing dynamic adjustments power management chip for the service data that mobile terminal device is different; and then while not affecting mobile terminal device work; ensure charge efficiency; in addition when mobile terminal device is when power consumption is lower; the function of increasing pressure of powered-down managing chip, has the effect of protection battery, extending battery life.
