1. A method of producing a battery carrier, the method comprising:
joining a tray plate to a cooling plate having at least one preshaped cooling duct;
forming the tray plate jointly with the cooling plate to produce a battery tray, wherein
during the forming of the tray plate and the cooling plate, the tray plate is deep-drawn jointly with the cooling plate to produce the battery tray, and a cooling duct section of the cooling duct is bent around an edge of the battery tray to form a bend of the cooling plate, and
the cooling plate has a material store which is formed into the bend of the cooling duct during the forming; and
finishing the battery carrier, wherein
the cooling duct is provided with connection elements, and
during the finishing, the cooling duct in the cooling plate is finally shaped, wherein an internal pressure is applied to the cooling duct for final shaping of the cooling duct,
during bending of the cooling duct around the edge of the battery tray, a cross section of the cooling duct is reduced,
for the final shaping of the cooling duct, the internal pressure is applied, in a hydraulic or pneumatic manner, to the cooling duct to restore the cross section that is reduced during the bending,
in the joining, the tray plate and the cooling plate are joined to one another to obtain a two-layer body, and
in the forming,
the two-layer body formed from the tray plate and the cooling plate is arranged in a deep-drawing tool, and the tray plate is then deep-drawn jointly with the cooling plate, and
during deep-drawing of the tray plate and the cooling plate, the cooling duct section of the cooling duct is bent around the edge of the battery tray.
