Power supply unit for aerosol inhaler and control method and program of power supply unit for aerosol inhaler
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.
1. A power supply unit for an aerosol inhaler, the power supply unit comprising:
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 for the power supply;
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, wherein
the charging controller sets a duty ratio to a value that is 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 is obtained by dividing a time during which the charging controller performs the first control by a unit time.
2. The power supply unit according to claim 1 , wherein
the charging controller sets the duty ratio such that the temperature of the power supply does not reach a predetermined threshold during a time that the duty ratio is greater than 0 and smaller than 100.
3. The power supply unit according to claim 2 , wherein
the duty ratio is a fixed value or a variable.
