A battery unit for a favor inhaler includes a chargeable and dischargeable power supply, a connection part capable of electrically connecting to an external charger, and a controller configured to perform control regarding at least the power supply, wherein when an accumulated value of a connection time period to the charger exceeds a first predetermined time period, the controller determines that the power supply has been degraded.

Disclosed is a power supply device for an aerosol generation device. The aerosol generation device includes an atomizer and the power supply device. An airflow passage is formed inside the atomizer. The power supply device includes a power supply main body and a sensor. A sensing passage, a filtering chamber and a communication hole are provided inside the power supply main body, the sensing passage and the filtering chamber are separated, and the communication hole is in communication with the sensing passage and the filtering chamber; the sensor is arranged in the sensing passage; a connecting end used for being connected to the atomizer is provided at one end of the power supply main body, and a through hole is provided in the connecting end. The power supply device can intercept solids and/or liquids entering the sensing passage from the communication hole and influencing the detection of the sensor.

An apparatus and a method for an aerosol generating device is described, the apparatus including a control module and a charging controller. The charging controller is configured to control charging of a battery at a first charging rate in a first charging mode and to control charging of the battery at a second charging rate, lower than the first charging rate, in a second charging mode. The control module is configured to determine whether the aerosol generating device is in use. The charging controller, when operating in the second charging mode, is configured to change the charging mode to the first charging mode in the event that the control module determines that the aerosol generating device is in use.
