1. A battery box having a plurality of orientation independent electrochemical cells, of the type in which said cells are arranged into at least one cell group, with flow channels formed between adjacent cells within said cell groups, through which a fluid can flow, a distributor channel being arranged in a first region of said box and coupled in fluid communication with said fluid flow channels at an inlet end thereof, and a collector channel being arranged in a second region of said box opposite said first region and coupled in fluid communication at an outlet end thereof, wherein:

  • in an installed orientation of said battery box, said cells are arranged in a horizontal orientation having the smallest dimension thereof in a vertical direction;

    cells within a cell group are stacked one above the other;

    each cell group has associated therewith inlet and outlet flow channels which extend transversely with respect to said battery box;

    the transverse inlet flow channel is connected in fluid communication with the distributor channel and to the flow channels of a cell group associated therewith; and

    the transverse outlet flow channel being connected in fluid communication with the collecting channels and the flow channels of an associated cell group.
