1. A shutdown method, applicable to a terminal, wherein the terminal is provided with a rechargeable battery, and the method comprises:
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.
