- the carrier element forms in particular a plane (X, Y plane) in which the battery cells can be arranged or will be arranged, with their longitudinal axes being perpendicular to the plane of the carrier element.
- the battery cells can in particular be arranged or arranged in the carrier element in such a way that the carrier element is arranged at a distance from both end faces of the battery cells, in particular at the same distance from the respective end face, which enables the battery cells to be held centrally with respect to their longitudinal axis. Because the end faces of the battery cells are not covered by the carrier element, or the carrier element is arranged in a central region along the longitudinal axis of the battery cells, additional functional components, such as heat exchange devices, can be arranged in the free end regions of the battery cells.
- the battery cells can be fixed or positioned using a carrier element without having to be arranged on a base or before the battery cells are glued or cast.
- the heat exchange element can be arranged on a free lateral surface or cell jacket of the battery cells, in particular a heat exchange element can be arranged on the battery cells on both sides of the carrier element, whereby utilization of an available lateral surface for heat transfer between the heat exchange element and battery cells can be improved.

It can be provided that the heat exchange element or elements is arranged on one side of a cell row formed by the battery cells, which is intended for the arrangement of a further carrier element.
- carrier elements are first equipped with battery cells, and a heat exchange element is arranged on one side of the rows of cells, and these are each assembled or bonded to a carrier element equipped with battery cells and heat exchange element.
- the invention is based in particular on the idea of prepositioning battery cells for the production of a high-voltage storage module in order to achieve a defined spacing.
- the carrier element is designed as a holder for the battery cells, which on the one hand specifies a fixation of the battery cells next to each other in cell rows in the whose connecting elements are determined.
- bonding of the battery cells to a trough or other support element can be improved, in particular accelerated, since a, in particular complete, hardening of a first row of battery cells is not necessary since they are held in position by means of the carrier element.
- a second row of cells can be arranged essentially immediately following each other, without any spatial displacement or distortion of the battery cells relative to one another being expected.
- the production of a high-voltage storage module can be accelerated, in particular while improving dimensional tolerance compliance, which can make cost savings and increases in quantity possible.
- the carrier element can be connected to the further carrier element in such a way that at least one heat exchange element can be arranged between two carrier elements, in particular between two rows of cells formed by the carrier elements.

- the battery cells of adjacent rows can be arranged closer to one another on their jacket sides, so that a wavy and/or slightly meandering longitudinal shape results for the gap because corresponding cells of the adjacent cell rows would overlap one another if they were not arranged offset from one another.
- the heat exchange element to be arranged or arranged can have a meandering shape in its longitudinal extent in order to be able to be arranged between two rows of cells arranged in this way.
- the carrier element can be set up to accommodate battery cells and/or to be connected to a further carrier element in such a way that the cell rows are arranged parallel to one another, with battery cells of adjacent cell rows each lying on an axis in order to be able to meet application-related requirements, for example.

Due to the spatial positioning or securing provided by the carrier element, accidental or process-related slipping or displacement of the battery cells relative to one another can be avoided. In this way, for example, a summation of several tolerance-related deviations in an arrangement of several cell rows can be avoided or reduced in order to avoid a reduction in positionable battery cell rows in a predetermined installation space.
- the positioning elements each have a cylindrical recess, the centers of which lie on an axis, the recess being designed to accommodate a battery cell.
- the recess is in particular designed to hold or fix the battery cell on the circumference, whereby a distance between the battery cells on an X-axis is specified.
