Abstract
A shutdown method applicable to a terminal having a rechargeable battery, the method includes: determining a first impedance and a second impedance of the rechargeable battery, wherein the first impedance is an impedance determined based on a current temperature of the rechargeable battery, and the second impedance is an impedance determined based on a current number of charge times of the rechargeable battery; determining a target impedance as a larger impedance value from the first impedance and the second impedance; determining a shutdown voltage of the terminal based on a preset open circuit voltage of the rechargeable battery, the target impedance and a current operating current of a charging circuit; and controlling the terminal to shut down, when an operating voltage of the rechargeable battery is decreased to the shutdown voltage.
