Title
(DE) BATTERIEMODUL

(FR) MODULE DE BATTERIE
Abstract
(DE)
Es wird ein Batteriemodul mit einem Grundkörper (1) zur Aufnahme einzelner, be-züglich einer Fügeachse (2) parallel angeordneter Batteriezellen (4), der einen quer zur Fügeachse (2) verlaufenden Strömungskanal (6) für ein die Zellenmäntel der Batteriezellen (4) direkt anströmendes Temperierfluid bildet, beschrieben.Um nicht nur die Gefahr thermischer Beschädigung einzelner Batteriezellen (4) bei Spitzenbelastungen zu verringern, sondern auch die Ausbreitung einer Kettenre-aktion im Fehlerfall eines thermal runaway zu vermeiden, wird vorgeschlagen, dass dem Strömungskanal (6) in Richtung der Fügeachse (2) je Batteriezelle (4) jeweils eine die Batteriezelle (4) umfangseitig mit Spiel unter Ausbildung eines Luftspaltes (10) umschließende Berstschutzhülse (7, 8) vor- und nachgelagert ist, wobei sich der Strömungskanal (6) über eine Höhe von 28 – 60% der Batteriezelle (4) und jede Berstschutzhülse (7, 8) für sich über eine Höhe von 20 – 36% der Batteriezelle (4) erstrecken.
(EN)
A battery module is described with a main part (1) for receiving individual battery cells (4) arranged in parallel with respect to a joining axis (2), which main part forms a flow channel (6), extending transversely to the joining axis (2), for a temperature-control fluid flowing directly against the cell shells of the battery cells (4). In order not only to reduce the risk of thermal damage to individual battery cells (4) during peak loads, but also to prevent the spread of a chain reaction in the event of a thermal runaway failure, according to the invention, for each battery cell (4), a burst protection sleeve (7, 8) which surrounds the battery cell (4) circumferentially with a clearance, forming an air gap (10), is mounted upstream and downstream of the flow channel (6) in the direction of the joining axis (2), the flow channel (6) extending over a height of 28 - 60% of the battery cell (4) and each burst protection sleeve (7, 8) extending over a height of 20 - 36% of the battery cell (4).
(FR)
L'invention concerne un module de batterie comprenant un corps de base (1) destiné à recevoir des cellules de batterie (4) individuelles, disposées en parallèle par rapport à un axe d'assemblage (2), qui forme un canal d'écoulement (6) s'étendant transversalement à l'axe d'assemblage (2) pour un liquide d'équilibrage thermique s'écoulant directement sur les enveloppes des cellules de batterie (4). L'invention vise non seulement à réduire le risque de dommage thermique des cellules de batterie (4) individuelles lors des pics de charge, mais aussi à prévenir la propagation d'une réaction en chaîne en cas de défaillance due à un emballement thermique, et se caractérise à cet effet en ce que, pour chaque cellule de batterie (4), une gaine de protection contre l'éclatement (7, 8), qui entoure respectivement une cellule de batterie (4) du côté de sa périphérie avec un certain jeu en formant un intervalle d'air (10), est disposée en amont et en aval du canal d'écoulement (6) dans la direction de l'axe d'assemblage (2), le canal d'écoulement (6) s'étendant sur une hauteur de 28 à 60 % de la cellule de batterie (4) et chaque gaine de protection contre l'éclatement (7, 8) s'étendant sur une hauteur de 20 à 36 % de la cellule de batterie (4).
