[0031] Such as figure 1 Shown is a schematic structural diagram of a dual battery switching system provided by a preferred embodiment of the present invention. in figure 1 , The dual battery switching system includes: a mobile terminal 10 and an external battery 20 detachably installed in the mobile terminal 10. The mobile terminal 10 includes a built-in battery 11 for powering the mobile terminal 10. The elastic contacts of the external battery 20 are electrically connected with the corresponding metal contacts of the mobile terminal 10 to provide power for the mobile terminal 10. According to actual use needs, the mobile terminal 10 selects the built-in battery 11 or the external battery 20 for power supply by switching batteries.
[0032] In practical applications, when the mobile terminal 10 detects that it is electrically connected to the external battery 20, there are the following three application modes:
[0033] Mode 1:
[0034] The mobile terminal 10 switches to the powe...

[0052] Based on the dual battery switching system and circuit in the first embodiment, the second embodiment of the present invention proposes a dual battery switching method, which is applied to MCU250. Such as Figure 7 As shown, it is a schematic flow chart of the dual battery switching method in this embodiment. in Figure 7 , The method includes:
[0053] Step 710, determine whether the external battery is inserted into the mobile terminal; if yes, go to step 720, if not, then the process ends;
[0054] Step 720, it is judged whether to select the internal battery power supply or the external battery power supply; when the internal battery power supply is selected, go to step 730, and when the external battery power supply is selected, go to step 750;
[0055] Step 730: Connect the internal battery power supply circuit of the built-in battery;
[0056] Step 740, determine whether the power of the built-in battery is lower than the first preset value; if yes, go to step 750, if n...

[0067] Such as Figure 8 As shown, the third embodiment of the present invention provides a schematic diagram of a hardware architecture of a mobile terminal. in Figure 8 , The terminal includes: a memory 810, a processor 820, and a dual battery switching program 830 stored on the memory 810 and running on the processor 820. In this embodiment, the dual battery switching program 830 includes a series of computer program instructions stored on the memory 810. When the computer program instructions are executed by the processor 820, the dual battery switching program 830 of the embodiments of the present invention can be implemented. Switch operation. In some embodiments, the dual battery switching program 830 may be divided into one or more modules based on specific operations implemented by various parts of the computer program instructions. Such as Picture 9 As shown, the dual battery switching program 830 includes: a judgment module 910, a charging module 920, and a disco...
