Abstract
An aerosol generation device includes a heater configured to generate an aerosol by heating an aerosol generating substrate; and a controller configured to control power to be supplied to the heater by a battery using a control signal, wherein the controller is further configured to identify state information of the battery at a heating start time point when the heater starts to be heated and calculate a duty ratio of the control signal based on the identified state information.
Claims19
An aerosol generation device comprising:
- a heater configured to generate an aerosol by heating an aerosol generating substrate;
- and
- a controller configured to control power to be supplied to the heater by a battery using a control signal,
- wherein the controller is further configured to:
- identify state information of the battery at a heating start time point when the heater starts to be heated, and
- calculate a duty ratio of the control signal based on the identified state information such that time taken for the heater to reach a predetermined temperature is constant regardless of a nonzero voltage value of the battery at the heating start time.
