Claim 8:
9. A power supply control method of an aerosol inhaler, the aerosol inhaler including a power supply that is able to discharge power to a load for generating an aerosol from an aerosol generation source, the power supply control method comprising:
a control step of controlling at least one of charging and discharging of the power supply such that the power supply does not become one or both of a fully charged state and a discharging termination state,
wherein a remainder which is obtained by subtracting an amount of power stored in the power supply to cause the discharging to be prohibited from an amount of power stored in the power supply in a state where the charging is completed is defined as a discharging permission power amount,
wherein, in a state where the charging of the power supply is completed, when detecting a deteriorated battery in accordance with a first numerical index, indicating a deteriorated state of the power supply and based on a calculation using an internal resistance value of the power supply, being equal to or larger than a first threshold indicating a threshold deteriorated state of the power supply or a second numerical index, indicating a healthy state of the power supply and based on a calculation using a full charge capacity of the power supply, being smaller than a second threshold indicating a threshold healthy state of the power supply, the power supply control method further comprises a control step of controlling at least one of the charging and the discharging of the power supply such that the discharging permission power amount becomes equal to or larger than an amount of power required to be supplied to the load in order to empty the aerosol generation source which is unused,
wherein the calculation using the internal resistance value is dividing an internal resistance value of the power supply in a current state by an internal resistance value of the power supply in a brand new state, and
wherein the calculation using the full charge capacity is dividing a full charge capacity of the power supply in the current state by a full charge capacity of the power supply in the brand new state.
