SYSTEM FOR MANAGING ENERGY FOR AN AIRCRAFT WITH A HYBRID POWER SOURCE COMPRISING AT LEAST ONE RECHARGEABLE ELECTRICITY SOURCE AND ONE ELECTRICITY GENERATING SOURCE

A power management system for an aircraft with a hybrid power source comprises a rechargeable electricity source and an electricity generating source, a detector determining status data of the elements of the aircraft power consumption electrical circuit, and power data relating to the instantaneous electrical power demanded by the aircraft and/or the charging status of the rechargeable electricity sources, an automaton receiving the power data from the detector and determining a control status for the power sources, an adapter determining a backup electrical configuration when the status data indicate a failure, a controller determining an electrical control for the rechargeable electrical source and the electrical generating source based on the instantaneous electrical power demanded, and a switch emitting commands to the switches of the aircraft power consumption electrical circuit to implement a nominal electrical configuration, or, a backup electrical configuration for the adapter in case of receipt thereof.
