1. A battery module, comprising:
a row of battery cells arranged parallel to each other and aligned along a longitudinal axis, the battery cells being arranged at a distance from each other so that adjacent battery cells define a gap allowing a temperature control fluid for the battery cells to pass therethrough; and
a holding device including a main body, a plurality of spacers and retaining means, wherein:
each spacer includes a mounting foot and a separator plate integrally formed with the mounting foot, the separator plate being arranged in the gap between two adjacent battery cells and configured to separate a first pass of the temperature control fluid and a second pass of the temperature control fluid,
the mounting feet are slidably mounted parallel to the longitudinal axis on the main body in at least one row, thus defining a sliding connection therebetween,
the retaining means comprises a first axial stop arranged at a first axial end of the row of battery cells and a second axial stop arranged at the second axial end of the row of battery cells, and
the retaining means comprises axial clamping means which axially compress the second axial stop against the battery cell located at the second axial end of the row of battery cells, the second axial stop thus compressing the row of battery cells and the separator plates arranged therebetween against the first axial stop, the mounting feet comprising an axial clearance therebetween so that the row of battery cells and the separator plates arranged therebetween are kept fixedly clamped.
