Abstract
(DE)
Ein Batteriesystem mit einer Mehrzahl von Batteriemodulen, die jeweils eine oder mehrere Batteriezellen umfassen, einem Gleichspannungszwischenkreis mit einem ersten Pol und einem zweiten Pol, und einem zwischen den Gleichspannungszwischenkreis und einen Anschluss für ein Energieversorgernetz geschalteten Umrichter, welcher ausgebildet ist, eine Wechselspannung des Energieversorgernetzes in eine Gleichspannung umzurichten und an den Gleichspannungszwischenkreis auszugeben, sowie eine Gleichspannung des Gleichspannungszwischenkreises in eine Wechselspannung umzurichten und an das Energieversorgernetz auszugeben. Die Batteriemodule verfügen über jeweils einen DC/DC-Umsetzer und sind über den jeweils einen DC/DC-Umsetzer mit dem Gleichspannungszwischenkreis verbunden.
(EN)
The invention relates to a battery system, comprising a plurality of battery modules, each having one or more battery cells, a direct voltage intermediate circuit having a first pole and a second pole, and a converter connected between the direct voltage intermediate circuit and a connection for an energy supplier network, said converter being designed to convert an alternating voltage of the energy supplier network into a direct voltage and to output it to the direct voltage intermediate circuit, and to convert a direct voltage of the direct voltage intermediate circuit into an alternating voltage and to output it to the energy supplier network. Each battery module has a DC/DC converter and the modules are connected to the direct voltage intermediate circuit by means of the respective DC/DC converter.
(FR)
L'invention concerne un système de batterie comprenant une pluralité de modules de batterie pourvus chacun d'un ou de plusieurs éléments de batterie, un circuit intermédiaire à tension continue pourvu d'un premier pôle et d'un second pôle, ainsi qu'un convertisseur monté entre le circuit intermédiaire à tension continue et un raccord pour un réseau d'alimentation en énergie. Le convertisseur est conçu pour convertir une tension alternative du réseau d'alimentation en énergie en une tension continue et pour fournir cette tension continue au circuit intermédiaire à tension continue, et pour convertir une tension continue du circuit intermédiaire à tension continue en une tension alternative et pour fournir cette tension alternative au réseau d'alimentation en énergie. Les modules de batterie disposent chacun d'un convertisseur continu-continu, par l'intermédiaire duquel ils sont reliés au circuit intermédiaire à tension continue.
