Abstract:
1. A method for shutdown of an electrical apparatus supplied by a plurality of electric power sources, each source being equipped with a management module, the method comprising: (a) identification of each source supplying the electrical apparatus, (b) reading data from the management module of each source, (c) determination of a global autonomy of the plurality of power sources with respect to said apparatus, wherein determination of the global autonomy comprises determination of a shutdown time of each source with respect to shutdown of a previously shut down source, the global autonomy of the plurality of sources being equal to the sum of said times, determination of the shutdown time of each source being performed by simulation of several shutdown steps, each shutdown step corresponding to shutdown of a source in chronological order of the shutdowns, the global autonomy of the plurality of sources being obtained by incrementing the shutdown time determined at each shutdown step, and (d) shutdown of the apparatus when at least one shutdown criterion of the apparatus has been achieved, said shutdown criterion depending on a shutdown time of said apparatus.
