A method for optimizing the architecture of the power supply of a load, includes the following steps: determination of a mission profile () sizing according to the power required by the load over time; definition of the sources of energy storage for hybridization; association of a characteristic behavior model with each source of energy storage; determination of the couples of sources of energy storage that can generate the mission profile with a minimum mass; and determination, from the potential couples of sources of energy storage, of the couple with the weakest mass.

Method for optimising the architecture of the power supply of a load

A device () for the electric power supply of a load (), includes at least two energy storage elements (), elements for determining the power needs of the load (), elements () for monitoring each energy storage element (), which are able to provide information about a maximum instantaneous power of each energy storage element (), a calculation body () for determining a maximum secured power according to the electromotive force (Ebat(t)) and the resistance (Rbat(t)) of the Th&#xe9;venin model, a maximum specified current and a maximum specified voltage, and elements (Cbat(t), Csc(t)) for controlling each energy storage element (), the elements being adjusted over time according to the power needs of the load () and the maximum secured power of each energy storage element ().
