Patent number: 10680294Abstract: 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 (SOHn) that are equal to SOH0-n×p %, where n is an integer comprised between 0 and 20/p.Type: GrantFiled: April 12, 2018Date of Patent: June 9, 2020Assignee: Airbus SASInventors: Benoit Ferran, Emmanuel Joubert, Clément Dinel

Publication number: 20180346139Abstract: 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.Type: ApplicationFiled: May 21, 2018Publication date: December 6, 2018Inventors: Benoit FERRAN, Emmanuel JOUBERT, Nicolas Fouquet, Jonathan LANDOLT
