Battery module and high-voltage accumulator

The invention relates to a battery module (1) for a high-voltage accumulator (34), in particular of an electrically drivable motor vehicle, having at least one electric storage cell (2), at least two plate-shaped frame components (3) which are arranged on the end faces and between which the electric storage cell (2) is arranged, at least one plate-shaped heat sink (4) with at least one cooling channel system (13) which is connected to the electric storage cells (2) in a thermally conductive manner, at least one fluid inlet (5) which is communicatively connected to the cooling channel system (13) via at least one first fluid connection (15), and at least one fluid outlet (14) which is communicatively connected to the cooling channel system (13) via at least one second fluid connection (16). The fluid inlet (5) and the fluid outlet (14) are arranged adjacently to a respective plate-shaped frame component (3) remotely from the heat sink, and at least one of the fluid connections (15, 16) has at least one first c
