1. An underbody arrangement of an electrically operable motor vehicle having a high-voltage storage device with a plurality of storage cells, comprising:
a floor panel of the electrically operable motor vehicle that is configured for an overlapping arrangement, at least in some regions, with the high-voltage storage device, upwardly in a direction of a vehicle height, wherein
the floor panel has at least one opening that is arranged in a depression of the floor panel which is a lowest point of the floor panel in the direction of the vehicle height, which opening is provided for drainage of a medium away from the depression of the floor panel via the at least one opening in the depression of the floor panel and is arranged in the direction of the vehicle height so as to overlap the high-voltage storage device, but is arranged without overlap with the battery cells of the high-voltage storage device between a vehicle doorsill laterally adjacent to the floor panel and a battery cell nearest to the vehicle doorsill in a vehicle transverse direction,
the high-voltage storage device has a storage cover, wherein the storage cover has a first region that overlaps at least a storage cell of the plurality of storage cells in the direction of the vehicle height and a second region that does not overlap the plurality of storage cells in the direction of the vehicle height, wherein the second region is flattened in terms of its height in the direction of the vehicle height, and wherein the first region has a greater height in the direction of the vehicle height than the flattened second region,
the at least one opening in the depression of the floor panel which is the lowest point of the floor panel in the direction of the vehicle height is disposed below the first region of the storage cover of the high-voltage storage device in the direction of the vehicle height.
