A charging system for an aerosol-generating device includes a processor and a memory in communication with the processor and configured to store instructions is provided. The instructions define at least one of a disable mode, an intra-session mode, or an inter-session mode. The processor is configured to execute the instructions to cause the charging system to detect when the device is connected to a charging device; activate a power source charger in response to the connection to the charging device; identify a selected mode; enable or disable a heater of the capsule dependent upon the selected mode; if the heater is enabled, display a first display indicating the connection of the charging device; if the heater is enabled, detect if a session of the aerosol-generating device is ongoing; and if the session is ongoing, enable or suspend charging in response to the identification of the selected mode.

A method of controlling a hot wire anemometer (HWA) of a nicotine e-vaping device includes controlling, by a first PID controller, a level of power applied by the nicotine e-vaping device to the HWA based on a temperature of a heated element of the HWA and a temperature setpoint; generating a puff detection signal indicating whether or not a puff is currently occurring with respect to the nicotine e-vaping device; and while the puff detection signal indicates that a puff is not currently occurring with respect to the nicotine e-vaping device, detecting, by a second PID controller, a change in an ambient temperature of the HWA, and controlling, by the second PID controller, the temperature setpoint such that the temperature setpoint changes in response to the detected change in the ambient temperature of the HWA.
