Title
(DE) VERARBEITUNG VON ZUSTANDSDATEN EINER BATTERIE ZUR ALTERUNGSSCHÄTZUNG
(EN) PROCESSING OF CONDITION DATA OF A BATTERY TO ESTIMATE AGEING
(FR) TRAITEMENT DE DONNÉES D'ÉTAT D'UNE BATTERIE POUR ESTIMER LE VIEILLISSEMENT
Abstract
(DE) Ein Verfahren zum Verarbeiten von Zustandsdaten (201, 210) einer Batterie (91-96) umfasst das Anwenden eines Autoencoder künstlichen neuronalen Netzwerks (310) auf initiale Zustandsdaten (201, 210). Daraus werden rekonstruierte (209) erhalten. Das Verfahren umfasst das Durchführen einer Alterungsschätzung basierend auf den rekonstruierten Zustandsdaten (209), um einen Zustandsindikator (99) zu erhalten, der indikativ für einen Alterungszustand der Batterie (91-96) ist.
(EN) The invention relates to a method for processing condition data (201, 210) of a battery (91-96) comprising the use of an auto-encoder of an artificial neural network (310) on initial condition data (201, 210). Reconstructed data (209) is obtained therefrom. The method comprises running an ageing estimate on the basis of the reconstructed condition data (209) to obtain a condition indicator (99) which is indicative of an ageing condition of the battery (91-96).
(FR) L'invention concerne un procédé de traitement de données d'état (201, 210) d'une batterie (91-96) consistant notamment à appliquer un réseau de neurones artificiels (310), sous la forme d’un encodeur, à des données d'état (201, 210) initiales. Des données d'état reconstruites (209) sont alors obtenues. Le procédé consiste ensuite à réaliser une estimation du vieillissement sur la base des données d'état reconstruites (209) pour obtenir un indicateur d'état (99) révélant un état de vieillissement de la batterie (91-96).
