Abstract:
Various example embodiments relate to a nicotine electronic vaping device, system, method, and/or non-transitory computer readable medium for protecting a nicotine electronic vaping device from overheating based on a steady state resistance prediction. The nicotine electronic vaping device may include a reservoir containing a nicotine pre-vapor formulation, a heating element configured to heat nicotine pre-vapor formulation drawn from the reservoir, and control circuitry configured to monitor a resistance value of the heating element over a first time period after a first application of negative pressure to the nicotine electronic vaping device, determine an estimated steady state resistance value of the heating element based on the monitored resistance value using a trained neural network, and control power to the heating element based on the estimated steady state resistance value.
