The invention relates to an arrangement (41) for measuring a cell in a rechargeable battery pack (43), wherein the rechargeable battery pack (43) comprises a series connection (13) composed of a plurality of cells (14, 14a, 14b), wherein two adjacent cells (14, 14a, 14b) are electrically interconnected by means of a connecting branch (20), and wherein the arrangement (41) has a measuring device (27) and comprises a switching device (19), which is equipped to selectively connect exactly one connecting branch (20) to a measuring input (22) of the measuring device (27). In order to provide an arrangement for measuring a single cell, in which the debalancing of the charge state of the individual cells (14, 14a, 14b) is at least substantially prevented due to the measurements by means of the measuring device, the arrangement (41) comprises at least one load (37) arranged between two connecting branches (20), the load (37) can selectively be brought into an activated operating state or into a deactivated operating state by means of a control signal (s) such that an electric charge can be withdrawn from at least one cell (14, 14a, 14b) during the activated operating state by means of the load (37). |
