Temperature control plate and battery cell arrangement

A battery cell arrangement comprising:

• a rechargeable electric battery comprising at least two battery cells arranged at a distance from one another along a stacking direction, and
• at least one temperature-control plate arranged in a sandwich-like manner, between the two battery cells, so that heat can be transferred between a temperature-control agent guided through the temperature-control plate and the battery cells,
• wherein the at least one temperature-control plate comprises:
• a plate-shaped base body that extends along a direction of extension and has a rectangular geometry in a cross-section perpendicular to the direction of extension with two opposing first sides each having a first dimension and two opposing second sides each having a second dimension, the first dimension greater than the second dimension,
• wherein the base body includes at least one first opening associated with a first temperature-control channel and at least one second opening associated with a second temperature-control channel, allowing the temperature-control agent flow through both channels, and the first temperature-control channel and the second temperature-control channel extend along the direction of extension and the first temperature-control channel and the second temperature-control channel open into mutually opposite end faces of the base body with respect to the direction of extension,
• wherein the at least one first opening is arranged between a first of the two first sides and the at least one second opening, the at least one second opening is arranged between a second of the two first sides and the at least one first opening, and
• wherein the base body further includes at least one third opening acting as a thermal insulation structure, which also extends along the direction of extension between the two end faces and is arranged between the at least one first opening and the at least one second opening.
