Abstract
Provided is an aerosol generating device having a function of estimating battery life, the aerosol generating device including a heater configured to generate an aerosol by heating an aerosol generating substance; a battery configured to supply power to the heater; a counter configured to count the number of usage times the aerosol generating device is used by a user, and a controller configured to control power supplied to the heater, wherein the controller estimates a remaining life of the battery based on at least two from among an initial output voltage of the battery, an output voltage of the battery dropped as the aerosol generating device is used for a counted number of usage times, and the counted number of usage times.
Claims20
An aerosol generating device comprising:
- a heater configured to generate aerosol by heating an aerosol generating substance;
- a battery configured to supply power to the heater;
- and
- a controller configured to estimate a remaining life of the battery based on at least two from among a first output voltage of the battery measured at a first time point, a second output voltage of the battery measured at a second time point that is later than the first time point, and a number of usage times of the aerosol generating device between the first time point and the second time point.
A method of estimating battery life of an aerosol generating device, the method comprising:
- measuring an initial output voltage of a battery;
- determining a number of available usage times of the aerosol generating device based on the initial output voltage of the battery;
- counting a number of usage times of the aerosol generating device;
- and
- estimating the remaining life of the battery based on an estimated current consumption of the aerosol generating device according to the number of usage times and an estimated initial current capacity of the aerosol generating device according to the number of available usage times.
A method of estimating battery life of an aerosol generating device, the method comprising:
- measuring a first output voltage of a battery at a first time point;
- counting a number of usage times of the aerosol generating device;
- measuring a second output voltage of the battery at a second time point after the number of usage times;
- and
- estimating the remaining life of the battery based on the first output voltage and the second output voltage.
