Abstract: A method and an architecture for implementing the method for the management of a hybrid thermal/electrical propulsion aircraft in the course of its various flight phases. The hybrid propulsion receives at each instant i a total power command Ptot,com,i distributed between thermal Pth,com,i and electrical Pe,com,i power commands. The method includes steps of calculating a maximum admissible thermal power command Pth,com,max,i for compliance with acoustic objectives on the ground, selecting the thermal power command Pth,com,i in a bounded range of values, determining the electrical power command Pe,com,i. The thermal Pth,com,i and electrical Pe,com,i power commands supplied by the hybrid propulsion are thus adjusted in the course of the different flight phases depending on a height hi of the aircraft in order to make it possible to comply with acoustic requirements on the ground.

Abstract: The vehicle receives batteries comprising cells arranged into at least one pack configured to be held in a vehicle structure, the pack being alternatively chosen from among at least one pack(P) and at least one pack(E) which are mechanically interchangeable and electrically substitutable. The pack(P) cells exhibit a maximum power density substantially higher than the pack(E) cells exhibit, and comprise cells exhibiting an energy density per unit mass substantially less than the pack(E) cells exhibit. The maximum electrical power of the pack(P) corresponds to the maximum electrical power needed to accomplish a first vehicle mission and the energy storage capacity of the pack(P) is at least sufficient to accomplish the first mission. The electrical energy storage capacity of the pack(E) corresponds to the electrical energy storage capacity needed to accomplish a second vehicle mission and the maximum electrical power is at least sufficient to accomplish the second mission.

Abstract: A charging system for electrical accumulator vehicle batteries, comprising a charging station principally designed to generate a charging current for the batteries, a system for thermally conditioning the batteries, by the circulation of a heat transfer fluid. A vehicle-mounted segment comprises a component for measuring the battery temperatures, a system for measuring the state of charge of the batteries, and a heat transfer fluid distribution circuit. A non-vehicle-mounted segment comprises a ground module of the thermal conditioning system for generating a flux of a heat transfer fluid, a control-command module designed to determine, during charging, as a function of the states of charge of the batteries and the battery temperatures, the flow rates and temperatures of the heat transfer fluid and a charging current required to achieve a target final state, characterized by a target temperature and a target charge at the end of a given charging time.

Abstract: A method for managing a battery according to a state of health of the battery, comprising, prior to using the battery, predetermining a maximum depth of discharge profile according to the state of health of the battery, the profile being dependent on a technology of the battery, on a nominal energy level to be made available each time the battery is discharged, the nominal energy level being substantially constant over a service life of the battery. While using the battery, a maximum depth of discharge of the battery is adjusted at regular intervals, each time the state of health of the battery decreases by a percentage corresponding to an update interval p % that is equal to p/100, that is, for all state of health values (SOHO that are equal to SOHo-n×p %, where n is an integer comprised between 0 and 20/p.
