Abstract: An aerosol generating device is provided, including a vaporiser configured to vaporise an aerosol-forming substrate; a battery connected to the vaporiser a control circuit configured to control a supply of power from the battery to the vaporiser; a memory storing a usage record of the device; and a replacement indicator configured to provide a signal to a user. The control circuit is configured to compare a measured voltage across the battery to a threshold voltage, and to generate an error signal to update the usage record if the measured voltage is less than the threshold voltage during an operation cycle. The control circuit is also configured to access the usage record and to activate the replacement indicator depending on the status of the usage record.

Abstract: There is provided a method of controlling an electrical heating element, including maintaining a temperature of the heating element at a target temperature by supplying pulses of electrical current to the heating element; monitoring a duty cycle of the pulses of electrical current; and determining if the duty cycle differs from an expected duty cycle or range of duty cycles, and if so, reducing the target temperature, or stopping the supply of current to the heating element or limiting the duty cycle of the pulses of electrical current supplied to the heating element. As the temperature is maintained at a known target temperature, any variation in the duty cycle or range of duty cycles expected to maintain the target temperature is indicative of abnormal conditions.
