A method and apparatus for ascertaining the maximum power obtainable from a traction storage-battery system that includes a plurality of storage-battery elements connected in series. The method provides for: determining at least one power indicator for each storage-battery element, and ascertaining a quantity of the smallest power indicators of all determined power indicators of all storage-battery elements. The quantity includes the smallest power indicator or a subgroup thereof of all power indicators of the storage-battery elements. A power-output limit for the quantity is provided, starting from the power indicators of the quantity. The maximum power obtainable from the traction storage-battery system is extrapolated based on the power-output limit and linked by the extrapolation and because of the series connection, to a power output of the at least one storage-battery element for which the quantity of the smallest power indicators was ascertained.
