1. A power supply unit which is installed in an inhaler device, comprising:
a battery;
a controller for controlling a charging operation of the battery and a discharging operation of the battery, the discharging operation being performed when atomizing or vaporizing an inhaled component source; and
a temperature measurer for measuring temperature of the controller,
wherein the controller is configured to:
control the temperature measurer to measure the temperature of the controller, in accordance with a first cycle during the charging operation and in accordance with a second cycle during the discharging operation, the second cycle having a length different from that of the first cycle,
in response to a result of the measurement, judge a temperature state of the power supply unit, and
in response to the temperature state being judged to correspond to a temperature abnormality, control the battery to stop the charging operation or the discharging operation, and
wherein controller is further configured to:
control the temperature measurer to measure temperature of the controller in a case that a puff action performed by a user is detected after the discharging operation is stopped or in a case that a connection of the power supply unit to an external electric power source is detected after stopping of the charging operation; and
in response to the measured temperature being in a predetermined normal temperature range, control the battery to restart the discharging operation or the charging operation.
