## 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.

## Claims

### Claim 1

A temperature control device for a battery system, said temperature-control device comprising:
a cuboid-shaped hollow body having a liquid space therein with at least one connection device configured to supply a separately temperature-controlled fluid to the liquid space and at least one connection device configured to discharge the separately temperature-controlled fluid,
the body having therein a plurality of regularly arranged and identically formed openings extending from a first body surface to a second body surface,
wherein each opening accommodates therein a respective cylindrical battery cell in a fluid-tight connection so that the fluid space in the hollow body is fluid-tight, and
wherein the hollow body, excluding the cell head and the cell bottom, extends over a height h of >20 to <100% of the total height H of the battery system.

### Claim 2 (depends on 1)

A temperature control device for battery cells according to claim 1, wherein each opening has a sealing element that encloses the cylindrical battery cells.

### Claim 3 (depends on 1)

A temperature control device for battery cells according to claim 1, wherein the cuboid-shaped hollow body is integrally made from plastic.

### Claim 4 (depends on 1)

A temperature control device for battery cells according to claim 1, wherein the openings (are arranged in a densest circular packing form.

### Claim 5 (depends on 1)

A temperature control device for battery cells according to claim 1, wherein the individual battery cells are spaced apart from each other.

### Claim 6 (depends on 1)

A temperature control device for battery cells according to claim 1, wherein the separately temperature-controlled fluid is pumped in circulation via a heating and/or cooling device.

### Claim 7 (depends on 1)

A temperature control device for battery cells claim 1, wherein the fluid is conductive.

### Claim 8 (depends on 1)

A temperature control device for battery cells according to claim 1, wherein the cuboid-shaped hollow body is integrally made from POM.

### Claim 9 (depends on 1)
