Inhalation component generation device, method of controlling inhalation component generation device, and program

An inhalation component generation device, comprising:

• a load configured to vaporize or atomize an inhalation component source with electric power from a power supply;
• a user interface;
• and
• a circuitry configured to
• acquire a value indicating a remaining amount of the power supply and acquire an operation request signal to the load to generate a command for operating the load;
• cause the user interface to perform first notification in a case that the value indicating the remaining amount of the power supply is less than a first threshold and equal to or more than a second threshold smaller than the first threshold;
• cause the user interface to perform second notification in a case that the value indicating the remaining amount of the power supply is less than the second threshold, wherein
• the first threshold is changeable based on an algorithm, wherein the algorithm is performed i) in response to the voltage of the power supply being equal to or lower than a discharge termination voltage of the power supply or ii) in response to the state of charge of the power supply becoming equal to or less than the state of charge or remaining amount corresponding to the discharge termination voltage, and
• the circuitry is configured to perform a smoothing process by which a primary first threshold derived by the algorithm approaches at least one of a plurality of the first thresholds that are previously changed and set the first threshold based on a value derived by the smoothing process.
