Battery unit, flavor inhaler, method of controlling battery unit, and program
Provided is a battery unit including: a power supply; a detector configured to detect an output voltage of the power supply; a connecting configured to be connectable with a load for atomizing an aerosol source or heating a flavor source; and a controller capable of executing a power supply mode in which electric power is supplied to the load from the power supply. The controller executes a specific control different from the supply of electric power to the load based on am amount of change in the output voltage per a predetermined time period in the power supply mode.
1. A battery unit, comprising:
a power supply;
a detector configured to detect an output voltage of the power supply;
a connection configured to be connectable with a load for atomizing an aerosol source or heating a flavor source; and
a controller capable of executing a power supply mode in which electric power is supplied to the load from the power supply, wherein
the controller executes a specific control different from the supply of electric power to the load based on an amount of change in the output voltage per a predetermined time period in the power supply mode,
the specific control is authentication of the load,
if the amount of change in the output voltage per a predetermined time period is not included in a predetermined range, the authentication of the load is cancelled, and
if the authentication of the load is cancelled, the controller determines whether the authentication of the load is performed based on the amount of change in the output voltage per a predetermined time period when a resume operation is detected.
2. The battery unit according to claim 1 , wherein
if the amount of change in the output voltage per a predetermined time period is included in a predetermined range, the authentication of the load is continued.
3. A flavor inhaler, comprising: the battery unit according to claim 1 ; and the load.
4. A battery unit, comprising:
a power supply;
a detector configured to detect an output voltage of the power supply;
a connection configured to be connectable with a load for atomizing an aerosol source or heating a flavor source; and
a controller capable of executing a power supply mode in which electric power is supplied to the load from the power supply, wherein
the controller executes a specific control different from the supply of electric power to the load based on an amount of change in the output voltage per a predetermined time period in the power supply mode,
the connection is capable of connecting with a charger for charging the power supply and the load,
the controller is capable of executing the power supply mode and a charge mode in which the charger charges the power supply,
the specific control is a control for determining an abnormality in the charge mode, and
if a decreasing amount of the output voltage per a predetermined time period in the charge mode is equal to or smaller than a first threshold which is set based on the decreasing amount of the output voltage per the predetermined time period in the power supply mode, the controller determines the abnormality in the charge mode.
5. The battery unit according to claim 4 , wherein
the first threshold is set to be equal to or smaller than the amount of change in the output voltage per the predetermined time period in the power supply mode.
6. The battery unit according to claim 4 , comprising:
a switch that is capable of electrically connecting or disconnecting the power supply to or from the load or the charger that is connected to the connection,
wherein the controller turns on the switch if a first condition is satisfied in the power supply mode, and the controller turns on the switch if a second condition different from the first condition is satisfied in the charge mode.
7. The battery unit according to claim 6 , comprising a detector configured to detect an operation for using the load,
wherein the first condition is a condition based on detection of the operation.
8. The battery unit according to claim 6 , wherein
the second condition is a condition based on connection of the charger to the connection.
9. A method of controlling a battery unit including a controller that is capable of executing a power supply mode in which electric power is supplied to a load from a power supply through a connection configured to be connectable with the load for atomizing an aerosol source or heating a flavor source, the method comprising the steps of:
detecting an output voltage of the power supply;
executing authentication of the load based on an amount of change in the output voltage per a predetermined time period in the power supply mode;
cancelling authentication of the load if the amount of change in the output voltage per a predetermined time period is not included in a predetermined range; and
determining, if the authentication of the load is cancelled, whether the authentication of the load is performed based on the amount of change in the output voltage per a predetermined time period when a resume operation is detected.
10. A non-transitory computer-readable storage medium storing a program causing a battery unit to execute the method according to claim 9 .
