Abstract
A power supply unit includes: a power supply configured to discharge power to a load for generating an aerosol from an aerosol generation source; a charger configured to convert inputted power into charging power; a temperature measuring unit configured to measure a temperature of the power supply; and a charging controller configured to perform a first control for stopping the charger from supplying the charging power to the power supply and a second control for causing the charger to supply the charging power to the power supply, the charging controller setting a duty ratio to a value greater than 0 and smaller than 100 in a case where the temperature of the power supply is within a predetermined range, and the duty ratio being obtained by dividing a time during which the charging controller performs the first control by a unit time.
