Temperature-control device for a battery system
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.
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.
2. A temperature control device for battery cells according to claim 1 , wherein each opening has a sealing element that encloses the cylindrical battery cells.
3. A temperature control device for battery cells according to claim 1 , wherein the cuboid-shaped hollow body is integrally made from plastic.
4. A temperature control device for battery cells according to claim 1 , wherein the openings (are arranged in a densest circular packing form.
5. A temperature control device for battery cells according to claim 1 , wherein the individual battery cells are spaced apart from each other.
6. 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.
7. A temperature control device for battery cells claim 1 , wherein the fluid is conductive.
8. A temperature control device for battery cells according to claim 1 , wherein the cuboid-shaped hollow body is integrally made from POM.
9. A battery pack with temperature-control devices connected in series according to claim 1 , wherein the separately temperature-controlled fluid is guided in circulation via temperature-control devices, at least one pumping device, and a heating and/or cooling device.
