Aerosol-generating device and operation method thereof

Abstract

An aerosol-generating device and an operation method thereof are disclosed. The aerosol-generating device of the disclosure includes a heater configured to heat an aerosol-generating substance, a battery configured to supply power to the heater, a temperature sensor disposed adjacent to the battery, and a controller. When charging of the battery is stopped, the controller monitors a value detected by the temperature sensor. When a result of monitoring the value detected by the temperature sensor satisfies a predetermined condition related to the battery, the controller determines the value detected by the temperature sensor to be a temperature of the battery. When the result of monitoring the value detected by the temperature sensor does not satisfy the predetermined condition, the controller determines a result of compensation of the value detected by the temperature sensor to be the temperature of the battery.
