Title: Battery replacing system and method thereof

Description:
BACKGROUND 
     1. Technical Field 
     The present disclosure relates to a battery replacing system and a method thereof. 
     2. Description of Related Art 
     Many electronic devices, such as cellular phones, laptop computers, and tablet computers, in addition to original batteries to provide power to the electronic devices, are also supplied with backup batteries. Although a backup battery is useful to replace the original battery when the original battery is not sufficiently charged, the electronic device needs to be shut off to switch between the original and the backup batteries, which can be very inconvenient. 
     Therefore, there is room for improvement within the art. 
    
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
       Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views. 
         FIG. 1  is a block diagram of a battery replacing system according to an embodiment. 
         FIG. 2  is a flow chart of a battery replacing method according to an embodiment. 
     
    
    
     DETAILED DESCRIPTION 
     The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.” 
       FIG. 1  shows a battery replacing system according to an embodiment. The battery replacing system is used to change out a battery of an electronic device. The electronic device includes a battery  10 . 
     The battery replacing system includes a power supply control circuit  20 , a switch circuit  30 , a power storage unit  40 , a charging circuit  50 , a battery replacing control module  60 , and a power saving control module  70 . The battery replacing control module  60  and the power saving control module  70  are installed in an operating system  15  of the electronic device. The battery replacing control module  60  and the power saving control module  70  are connected to the power supply control circuit  20 . The power supply control circuit  20  is connected to the switch circuit  30 . The battery  10  and the power storage unit  40  can provide power to the operating system  15  of the electronic device via the switch circuit  30 . The battery  10  is connected to the power storage unit  40  via the charging unit  50 . The battery  10  can charge the power storage unit  40  according to the charging unit  50 . The power supply control circuit  20  is connected to the battery  10  when the battery  10  is mounted to the electronic device, and can detect when the battery  10  is mounted to the electronic device. 
     The power storage unit  40  is configured to supply power to the operating system  15  during times no battery  10  is not mounted to the electronic device. In one embodiment, the power storage unit  40  is a super capacitor. 
       FIG. 2  shows an embodiment of a flow chart of a battery replacing method, which includes following steps: 
     In step S 201 , after an old battery  10  is used for a long time and needs to be replaced, the battery replacing control module  60  is triggered to send a battery replace signal to the power supply control circuit  20 . 
     In step S 202 , the power supply control circuit  20  sends a first switch control signal to the switch circuit  30 , the switch circuit  30  switches to the power storage unit  40 , the power storage unit  40  instead of the old battery  10  provides power to the operating system  15 , the power supply control circuit  20  triggers the power saving control module, and the operating system  15  switches from a normal mode to a power-save mode, in which peripheral devices of the electronic device are shut off and a screen of the electronic device turns dark. 
     In step S 203 , after the power supply control circuit  20  detects that the old battery  10  is detached from the electronic device and a new battery  10  is mounted on the electronic device, the power supply control circuit  20  sends a second switch control signal to the switch circuit  30 . The switch circuit  30  switches to the new battery  10 , and the new battery  10  instead of the power storage unit  40  provides power to the operating system  15 . 
     In step S 204 , the power saving control module  70  is turned off, the operating system  15  returns back to the normal mode, and the new battery  10  charges the power storage unit  40  according to the charging circuit  50  until the power storage unit  40  is full. 
     It is to be understood, however, that even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and functions of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
