Cooling device for a vehicle drive battery and vehicle drive battery assembly having a cooling device.

The invention relates to a cooling device (20) for a vehicle drive battery having a plurality of cylindrical battery cells (12) which are arranged one next to the other and have a lateral surface, an upper end wall and a lower end wall, wherein the vehicle drive battery has a flat side (18). The cooling device (20) comprises at least one cooling base (22) which bears in a planar fashion against the flat side (18) of the battery and has at least one coolant line (32), at least one heat-conducting contact plate (24) for making contact with the flat side (18), and at least one fastening device (36) for attaching the cooling base (22) to the flat side of the vehicle drive battery. The contact plate (24) has, along an axis running parallel to the flat side (18) of the battery, a profile with a constant cross section, preferably an extrusion profile.
