Abstract

The invention relates to an electrical energy storage device comprising: a plurality of flat storage cells for storing and discharging electrical energy, having opposing, flat current conductors, a plurality of spacer elements for maintaining a predetermined distance between the storage cells, and a clamping means for clamping the cells into a stack, wherein cells are clamped by the clamping means at the current conductors thereof between spacer elements by means of a force fit, wherein at least some of the spacer elements are designed as heat sinks. The heat sinks have fins extending sideways out from the stack. The heat sinks are alternatively thermally connected to the current conductors by means of a soft, heat conductive material. In a further alternative, two heat sinks are disposed between adjacent current conductors.; In a final alternative, the spacer elements comprise relief holes for weight reduction. The alternatives can be combined.

Description

technical field [0001] The invention relates to an electrical energy storage device with planar cells and a cooling body. Background technique [0002] Electrical energy storage cells are known in the form of planar and rectangularly structured storage elements. Such electrical energy storage units, for example so-called pouch units (Pouch-Zellen) or coffee bag units (Coffeebag-Zellen), as storage units (batteries, accumulators, capacitors, . The electrochemically active part of the device is surrounded by a film-like packaging through which the electrical terminals (electrodes), so-called (power supply) leads, in sheet form are guided. It is also known to form an electrical energy storage device from a plurality of such electrical energy storage units, which are combined into blocks by means of clamping devices. The electrical series or parallel connection of the units can be achieved by means of conductive contact elements which create an electrical connection between th...
