Abstract

An electric aircraft emergency power supply module, which is connectable to an electric charger, comprises: at least one electric power cell for storing and supplying electric energy; at least one voltage sensor for measuring the electric voltage (U) of the at least one electric power cell; and a controller for controlling a charging of the at least one electric power cell. Controlling the charging of the at least one electric power cell includes receiving a voltage indication signal (U(t)), indicative of the electric voltage (U) of the at least one electric power cell over time (t), from the at least one voltage sensor; determining the second derivative (U″(t)) of the voltage indication signal (U(t)) with respect to time (t); and on the basis of a positive-to-negative zero crossing of the second derivative (U″(t)) of the voltage indication signal (U(t)), simulating the behavior of a temperature sensitive element.
