Abstract
Die Erfindung betrifft einen Zellblock (1) für einen elektrischen Energiespeicher mit einer Mehrzahl nebeneinander angeordneter und elektrisch verschalteter Einzelzellen (2), wobei zwischen zwei Einzelzellen (2) jeweils eine gewellte plattenförmige Temperiervorrichtung (3) angeordnet ist. Erfindungsgemäß umfasst die jeweilige Temperiervorrichtung (3) eine Kanalstruktur, durch die ein Temperiermedium strömt, und die Temperiervorrichtung (3) weist aufgrund ihrer gewellten plattenförmigen Ausbildung eine Federfunktion in Richtung einer Längsachse (x) des Zellblockes (1) auf.The invention relates to a cell block (1) for an electrical energy store with a plurality of adjacent and electrically interconnected individual cells (2), a corrugated plate-shaped temperature control device (3) being arranged between two individual cells (2). According to the invention, the respective temperature control device (3) comprises a channel structure through which a temperature control medium flows, and the temperature control device (3) has a spring function in the direction of a longitudinal axis (x) of the cell block (1) due to its corrugated plate-shaped design.

Ein Zellblock für einen elektrischen Energiespeicher umfasst eine Mehrzahl nebeneinander angeordneter und elektrisch verschalteter Einzelzellen, wobei zwischen zwei Einzelzellen jeweils eine gewellte plattenförmige Temperiervorrichtung angeordnet ist. Erfindungsgemäß umfasst die jeweilige Temperiervorrichtung eine Kanalstruktur, durch die ein Temperiermedium strömt, und die Temperiervorrichtung weist aufgrund ihrer gewellten plattenförmigen Ausbildung eine Federfunktion in Richtung einer Längsachse eines aus einer Anzahl von Einzelzellen gebildeten Zellblockes auf.A cell block for an electrical energy storage device comprises a plurality of individual cells arranged next to one another and electrically interconnected, with a corrugated plate-shaped temperature control device being arranged between two individual cells. According to the invention, the respective temperature control device comprises a channel structure through which a temperature control medium flows, and due to its corrugated plate-shaped design, the temperature control device has a spring function in the direction of a longitudinal axis of a cell block formed from a number of individual cells.
Eine derart ausgebildete Temperiervorrichtung weist also sowohl eine Temperierfunktion als auch eine Federfunktion, d. h. Verspannfunktion, für den Zellblock auf, um Änderungen der Abmessungen in Richtung der Längsachse
Mittels der Temperiervorrichtung, d. h. mittels der Temperiervorrichtungen, ist eine Temperierung, insbesondere Kühlung, und eine mechanische Stabilität des Zellblockes verbessert, so dass eine Lebensdauer des Zellblockes und somit des elektrischen Energiespeichers erhöht werden kann bzw. können.By means of the temperature control device, d. H. By means of the temperature control devices, temperature control, in particular cooling, and mechanical stability of the cell block are improved, so that a service life of the cell block and thus of the electrical energy store can or can be increased.
