Fig. 1 is the functional block diagram of the electric supply installation shown in one embodiment of the invention.Fig. 1 is refer to, electric supply installation 10 has
There are external power input EXIN and power output end PWOUT, wherein external power input EXIN to can be used to connect by supplying
The external power source EXP that the outside of electric installation 10 is provided, such as by the transformer (AC of the AC powers such as connection source power supply
Adapter the dc source for) being provided.And power output end PWOUT is then used to be connected with an outside dress of supply power supply requirement
Put, for example the electronic apparatus such as smart mobile phone, notebook computer, panel computer.
Wherein, electric supply installation 10 includes charhing unit 110, battery 120, compress cell 130 and processing unit 140.Fill
Electric unit 110 couples external power input EXIN and power output end PWOUT.Battery 120 couples charhing unit 110 and power supply
Output end PWOUT.Compress cell 130 is coupled between battery 120 and power output end PWOUT.The coupling of processing unit 140 is charged
Unit 110, battery 120 and compress cell 130.
Wherein, when the detection external power input of charhing unit 110 EXIN receives external power source EXP, charhing unit 110
Directly output external power source EXP is to power output end PWOUT, and battery 120 is charged using external power source EXP.And work as and fill
Electric unit 110 does not receive external power source EXP from external power input EXIN, and power output end PWOUT is externally connected
During device (for example, electronic apparatus as described above), the output of battery 120 internal electric source INP to power output end PWOUT.
When the magnitude of voltage of the internal electric source INP of the detection output of battery 120 of processing unit 140 is less than reference voltage level, processing unit 140
Enable compress cell 130 is being pressurized internal electric source INP to load voltage value.
And in an embodiment of the present invention, when battery 120 exports internal electric source INP, processing unit 140 also detects internal
The current value of power supply INP.If when the current value of internal electric source INP is more than a current threshold, the enable of processing unit 140 supercharging is single
Unit 130 is being pressurized internal electric source INP to load voltage value.
