Abstract: A temperature control device for individual battery cells (2) assembled to form a module (1), having a base body (3) which, for the purpose of circumferentially enclosing the battery cells (2), comprises two opposing sealing elements (4, 5) having passage openings (6) located opposite one another in pairs with respect to a respective joining axis, and which base body (3) forms a flow channel extending transversely to the joining axes for a temperature control fluid is described.

Abstract: The invention relates to a temperature-control device (1) for a battery system, at least comprising a cuboid-shaped hollow body (2) with at least one connection device (3) for supplying and at least one connection device (4) for discharging a separately temperature-controlled fluid, a plurality of regularly arranged and identically formed openings (7) extending from a first body surface (5) to a second body surface (6), wherein a cylindrical battery cell (8) is accommodated by each opening (7), so that a fluid-tight liquid space is formed, which is characterized in that the hollow body (2), excluding the cell head (11) and the cell bottom (12), extends over a height h of >20 to <100% of the total height H of the battery system.
