Classification: CPC B  H  Y | IPC B  H

Claim 12:
13. A device for operating at least one electrical component of a vehicle using a battery, at least two battery cells of the battery being electrically connected and thus added to the at least one component via at least one switching unit, the device configured to:
precharge a DC link of the vehicle, by:
a) adding a first cell of the battery cells; and
b) incrementally adding at least a second of the battery cells, after a previous adding has taken place in each case;
wherein the incremental adding according to b) takes place as a function of an electric current detection in a current path of the switching unit used for the previous adding, wherein the electric current detection includes detecting current in the current path of the switching unit using electronics integrated in the battery;
wherein the at least one switching unit is integrated into the battery, and the at least one switching unit is controlled to perform the incremental adding by the electronics integrated into the battery;
wherein the incremental adding of b) takes place in each case only after a specific time duration has been reached, the specific time duration being ascertained using a timer of the battery.
