- the operation of detecting the auxiliary battery installation state of the auxiliary battery installation position can be realized by the controller 1.
- the level signal of the ID pin of the auxiliary battery mounting bit will change. Specifically, when the auxiliary battery is inserted into an auxiliary battery mounting position, the level signal of the ID pin of the auxiliary battery mounting bit will be high to low; on the contrary, when the auxiliary battery is pulled out from a certain auxiliary battery mounting position The level signal of the ID pin of the auxiliary battery mounting bit will be low to high.

- the first switch 5 in each circuit unit is typically in a closed state.
- the controller 1 selects the first battery with the largest voltage value and uses the first battery as the current power supply battery.
- the first battery has two alternative power supply schemes: one power supply scheme is that the second switch 6 is disconnected, and the current flows sequentially through the battery mounting position 3 and the diode 4 where the first battery is located.
- the first switch 5 to supply power to the terminal, at this time there will be a voltage drop of about 0.3V on the diode 4, which can be simply understood as: the voltage of the circuit unit has been lost without actually starting the power supply;

- the value is the largest, so the circuit unit in which the auxiliary battery is located will suppress the other two circuit units, so that the other two circuit units cannot supply power to the terminal.
- the voltage of the auxiliary battery may be reduced from 3.8V to 3.05V.
- the circuit unit where the main battery is located may The terminal provides a voltage of 3.2V, and the circuit unit where the other auxiliary battery is located can provide a voltage of 3.1V to the terminal.

- the value of the voltage difference threshold is not limited to 0.3 V, and may be determined according to actual conditions, which is not limited in this embodiment.
- the second battery when the difference between the voltage of the second battery and the voltage of the first battery is greater than the voltage difference threshold, for example, when the difference between the two is greater than 0.3V, it indicates that the first battery has been consumed in the power supply process. More power, at this time, using the first battery to supply power is not the optimal power supply scheme, so the second battery can be used to supply power to the terminal.
