Title
(DE) ELEKTRISCHER ENERGIESPEICHER FÜR EIN ELEKTROFAHRZEUG
(EN) ELECTRICAL ENERGY STORE FOR AN ELECTRIC VEHICLE
(FR) ACCUMULATEUR D'ÉNERGIE ÉLECTRIQUE POUR UN VÉHICULE ÉLECTRIQUE
Abstract
(DE) Die Erfindung betrifft einen elektrischen Energiespeicher (1) für ein Elektrofahrzeug, welcher eine Vielzahl an elektrisch miteinander verbundenen, insbesondere flachen und im Wesentlichen plattenförmigen Batteriezellen aufweist, welche in zumindest einem Stapel nebeneinander in einem gemeinsamen Gehäuse (8) angeordnet sind. Um die Lebensdauer des elektrischen Energiespeichers zu erhöhen und den Montageaufwand zu verringern, wird vorgeschlagen, dass der Innenraum des Gehäuses (8) mittels einer Saugpumpe (9) absaugbar, vorzugsweise evakuierbar ist.
(EN) The invention relates to an electrical energy store (1) for an electric vehicle, comprising a plurality of in particular flat and substantially plate-shaped battery cells that are electrically connected to one another and arranged next to one another in at least one stack in a common housing (8). In order to increase the service life of the electrical energy store and reduce the assembly complexity, according to the invention the interior of the housing (8) can be extracted, preferably evacuated, by means of a suction pump (9).
(FR) L'invention concerne un accumulateur d'énergie électrique (1) pour un véhicule électrique, lequel comporte une multitude d'éléments de batterie reliés électriquement entre eux, en particulier plats et sensiblement en forme de plaques, lesquels sont disposés dans au moins une pile les uns à côté des autres dans un boîtier (8) commun. L'invention vise à accroître la longévité de l'accumulateur d'énergie électrique et à réduire les dépenses de montage. A cet effet, l'intérieur du boîtier (8) est aspirable, en particulier évacuable à l'aide d'une pompe aspirante (9).
