In one embodiment of invention, the current processing unit is chosen as NPN triode.When current processing unit receives processor
During the control instruction that module 120 is sent, NPN triode moment will be amplified to the electric current that rated current is 1.5A with charging current and be
Battery of mobile terminal charges.
Specifically, the processor module 120 includes a memory cell, it is used to opening or stopping amplification for prestoring
The control instruction of pre-charge current.The memory cell includes the internal storage unit that storage receives request instruction again, with inside
The order register unit of the corresponding control instruction of the corresponding storage request instruction of memory cell.I.e. processor module 120 is received
After the high level pulse signal that time detecting module 140 is sent, the NPN triode inside processor module 120 is opened, output
Control signal 1 arrives current processing unit, controls the NPN triode of the inside modules to pre-charge current processing, current processing list
Member sends low level signal to processor module 120, and processor module 120 retrieves current processing list from its internal storage unit
The low level signal that member is sent asks the request instruction of processing event, extracts the request instruction and keeps in processor module 120
Built-in command deposit unit, calls the request instruction signal, outputs a control signal to current processing unit, then to precharge electricity
Flow enhanced processing.
Further, the mobile terminal pre-charge system, the also temperature including being connected with the processor module 120
Detection module 130, for to amplify the resistance protection unit detected in real time when pre-charge current charges as battery in battery
Temperature.It is mobile during quick charge is completed after current processing unit amplifies pre-charge current for battery of mobile terminal
The lithium battery of terminal by larger current after being charged, and the temperature of the resistance protection unit of lithium battery interior can be raised, so
Need to monitor the temperature of the resistance protection unit while for lithium cell charging.The present invention is used with temperature detecting module 130
Temperature to resistance protection unit is detected in real time, when the temperature of resistance protection unit is then stopped using higher than a controlled range
Electric current after amplification is lithium cell charging.
I.e. during NPN triode amplification pre-charge current, the temperature of the detection resistance protection location of temperature detecting module 130
Degree exceedes after controllable scope, and temperature detecting unit sends low level request signal to current processing unit, and request controls this to put
Big preliminary filling electric current.Current processing unit sends low level signal to processor module 120, it is desirable to treatment temperature detection module
The event of 130 requests, that is, ask current processing unit control NPN triode amplification preliminary filling electric current.Processor module 120 is out of it
Portion's memory cell retrieves the instruction of the low level signal request processing event of current processing unit transmission, extracts the instruction and keeps in
To the built-in command deposit unit of processor module 120, the command signal is called, current processing unit is output a control signal to,
The current amplification unit for stopping the NPN triode inside the processor module 120 is put to the electric current of mobile terminal lithium battery
