Abstract: A method for operating at least one electrical component of a vehicle with the aid of a battery. At least two battery cells of the battery are electrically connected and thus added to the at least one component via at least one particular switching unit. The following steps for precharging a DC link of the vehicle is carried out: a) adding a first of the battery cells, b) incrementally adding at least a second of the battery cells, after a previous adding has taken place in each case.

Abstract: A battery and a battery system including such a battery. The battery includes: a first and a second battery cell arrangement, each including at least one battery cell, a first switch, and a second switch, and an evaluation unit.
