ACCUMULATOR ARRANGEMENT

An accumulator arrangement for a hybrid or electric vehicle includes a plurality of battery cells which are stacked in a stacking direction to form at least one battery block. The at least one battery block is arranged in a housing of the accumulator arrangement. A cooling device includes a cooling plate arranged on one side on the battery block and extending parallel to the stacking direction. On the at least one cooling plate at least one cover plate with at least one cooling channel through which a coolant can flow is secured, facing away from the at least one battery block. The cooling plate forms an outer contour of the fluid-tight housing. The at least one cooling channel of the cover plate is open towards the at least one cooling plate and is closed by the at least one cooling plate.
