Abstract
A dynamic output power management unit for a heating circuit of an electronic smoking device includes a heating element connected to a power source via a first switching element. The unit has at least one voltage detection device to detect voltage values at various points of the heating circuit. A controller is configured to derive a resistance of the heating element, and estimate a discharge time or a power consumption value of the power source such that an energy converted in a period of time is substantially identical to a predetermined energy conversion value for a same period of time.
