Title
(DE) ENERGIESPEICHERANORDNUNG
(EN) ENERGY STORAGE ARRANGEMENT
(FR) ENSEMBLE D'ACCUMULATION D'ÉNERGIE
Abstract
(DE)
Die Erfindung bezieht sich unter anderem auf eine Energiespeicheranordnung (10), die zumindest eine Reihenschaltung (200) mit mindestens zwei in Reihe geschalteten Teilmodulen (220) und einer Induktivität umfasst, wobei zumindest eines der Teilmodule (220) einer oder mehrerer der Reihenschaltungen (200) ein Eingangsmodul (221) und ein zumindest einen elektrischen Energiespeicher aufweisendes Speichermodul (223) umfasst. Erfindungsgemäß ist vorgesehen, dass elektrisch zwischen dem Eingangsmodul (221) und dem Speichermodul (223) ein Umpolmodul (222) geschaltet ist, das in einem Normalbetriebsmodus und einem Polaritätsumpolbetriebsmodus betrieben werden kann, wobei das Umpolmodul (222) im Normalbetriebsmodus die Ausgangsspannung des Eingangsmoduls (221) mit - verglichen mit der Ausgangsspannung des Speichermoduls (223) - derselben Polarität an das Speichermodul anlegt und wobei das Umpolmodul (222) im Polaritätsumpolbetriebsmodus die Ausgangsspannung des Eingangsmoduls (221) mit - verglichen mit der Ausgangsspannung des Speichermoduls (223) - der inversen Polarität an das Speichermodul anlegt.
(EN)
The invention relates, inter alia, to an energy storage arrangement (10) that comprises at least one series circuit (200) having at least two submodules (220) connected in series and one inductor, at least one of the submodules (220) of one or more of the series circuits (200) comprising an input module (221) and a storage module (223) that has at least one electrical energy store. According to the invention, a pole-changer module (222) is electrically connected between the input module (221) and the storage module (223), and can be operated in a normal operating mode and in a polarity changer operating mode. When in the normal operating mode, said pole-changer module (222) applies, to said storage module, the output voltage of the input module (221) at the same polarity as the output voltage of the storage module (223) and, when in the polarity changer operating mode, the pole-changer module (222) applies, to said storage module, the output voltage of the input module (221) at the inverse polarity to that of the output voltage of the storage module (223).

L'invention concerne entre autre un ensemble d'accumulation d'énergie (10) qui comprend au moins un montage série (200) d'au moins deux modules partiels (220) connectés en série et d'une inductance, au moins l'un des modules partiels (220) de l'un ou de plusieurs montages série (200) comprenant un module d'entrée (221) et un module d'accumulation (223) présentant au moins un accumulateur d'énergie électrique. Selon l'invention, un module d'inversion de polarité (222) est connecté électriquement entre le module d'entrée (221) et le module d'accumulation (223), lequel module d'inversion de polarité pouvant fonctionner dans un mode de fonctionnement normal ou dans un mode de fonctionnement inversion de polarité. Le module d'inversion de polarité (222), lorsqu'il se trouve en mode de fonctionnement normal, applique au module d'accumulation la tension de sortie du module d'entrée (221) avec la même polarité que celle de la tension de sortie du module d'accumulation (223), et le module d'inversion de polarité (222), lorsqu'il se trouve en mode de fonctionnement inversion de polarité, applique au module d'accumulation la tension de sortie du module d'entrée (221) avec une polarité inversée par rapport à celle de la tension de sortie du module d'accumulation (223).
