Steady state resistance estimation for overheating protection of a non-nicotine e-vaping device

A method of operating a non-nicotine electronic vaping device (EVD), the method comprising:

• monitoring, using control circuitry of the non-nicotine EVD, a resistance value of a heating element included in the non-nicotine EVD over a first time period after a first application of negative pressure to the non-nicotine EVD, the heating element heating non-nicotine pre-vapor formulation drawn from a reservoir of the non-nicotine EVD, the non-nicotine pre-vapor formulation being devoid of nicotine and including at least one non-nicotine compound;
• determining, using the control circuitry, an estimated steady state resistance value of the heating element based on the monitored resistance value using a trained neural network;
• and
• controlling, using the control circuitry, power to the heating element based on the estimated steady state resistance value.

A non-nicotine electronic vaping device (EVD) comprising:

• a reservoir containing a non-nicotine pre-vapor formulation, the non-nicotine pre-vapor formulation being devoid of nicotine and including at least one non-nicotine compound;
• a heating element configured heat non-nicotine pre-vapor formulation drawn from the reservoir;
• heater resistance monitoring circuitry configured to,
• determine a peak resistance value of the heating element during a first time period after a first application of negative pressure to the non-nicotine EVD, and
• determine at least one additional resistance value of the heating element during the first time period;
• a trained neural network configured to,
• estimate a steady state resistance value of the heating element during the first time period based on the determined peak resistance value and the determined at least one additional resistance value;
• and
• control circuitry configured to disable power to the heating element based on the estimated steady state resistance value.
