An inhalation component generating device, comprising:
- a power supply;
- a load that evaporates or atomizes an inhalation component source by power from the power supply;
- a control circuit that performs control based on an output of a temperature sensor and a sensor which outputs a generation request of an inhalation component;
- and
- a current sensor that outputs a charging/discharge current value of the power supply or a voltage sensor that outputs an output voltage value of the power supply,
- wherein the control circuit performs:
- a process (a) of calculating power supply temperature based on the output of the temperature sensor;
- a process (b1) of determining whether the power supply temperature is in a first temperature range, and performing deterioration diagnosis on the power supply only in a case where the power supply temperature is in the range;
- a process (b2) of performing the process (b1) in response to detection of the generation request;
- and
- a process (c1) of determining whether the power supply temperature is in a second temperature range in which discharge of the power supply is allowed, or whether the power supply temperature is in a third temperature range in which charging of the power supply is allowed, prior to the process (b1),
- wherein the control circuit is configured to perform the deterioration diagnosis based on an output value of the current sensor or the voltage sensor at any one of a timing in a course of discharge of the power supply, a timing immediately before discharge, a timing immediately after discharge, a timing in a course of charging, a timing immediately before charging, and a timing immediately after charging.
